On March 3rd 2015, the company publicly released preliminary measurement results, specifically Frequency Response specifications. These results not only substantiated the technology’s advantages over comparable analog speaker technologies, but exceeded the company’s own performance objectives. The results demonstrated sound pressure levels (SPL) within the low frequency spectrum that were previously believed to be unattainable within a micro form factor; measuring 80dB (decibels) at 250Hz (at 10cm) for a standalone chip that is half the size of a standard micro-speaker. But this is just half the story. The industry has for decades been relying on frequency response specifications to describe the quality of a speaker. However a speaker’s fidelity is not solely dependent on the width or range of frequencies it can produce, but also on additional essential attributes. To accurately reproduce recorded content and sound truly “lifelike” a speaker must also: a. Have a “flat” frequency response (i.e. have small loudness variations between different frequencies within the audible range). This objective of reproducing all musically relevant tones, at the same volume is more commonly known “flat”. In speakers flat is good, as the “flatter” the response the closer the speaker is to accurately reproducing the original sound. Conventional micro speakers have distinct double-humped shape with significant variation (typically 10-15dB) between the peaks and valleys. Even high-end, audiophile speakers have loudness variations of 1-3dB within their range. When examining the preliminary performance results recently released by the company, one notices a perfectly linear frequency response “curve” – that is sloped at 6dB per octave. As has been previously announced the 6dB per octave slope, which is a native phenomenon to the digital sound reconstruction technique, is correctable (in real-time) via our software algorithms and would result in flatness variations smaller than 1dB. In essence what this means is that our speakers do not impose the physical constraints inherent in conventional speakers, rather our chips allow the music to be heard as it was recorded. Have low harmonic distortion. Distortion is considered by experts to be perhaps the most significant problem affecting perceived sound quality. Typical analog speakers generate certain “amounts” of harmonic distortion. Harmonic distortion means the speaker is producing frequencies that are not present in the original recording (but instead are multiplications of the recorded frequencies). Typically, the distortion becomes larger at lower frequencies and can reach values of 15-20% in micro-speakers. For a reference, the human distortion detection threshold is considered at 0.25%. The company’s digital speakers have a maximum distortion level of 0.1%. c. Have fast response to transient events. This lesser known yet critical parameter determines how quickly or slowly a speaker can faithfully reproduce sudden waveforms (“transients”). A transient is a short duration, high level sonic energy peak, such as a hand-clap or snare drum hit. To accurately reproduce most any sound in the percussion family the speaker must have excellent transient response. The transient response performance of a conventional speaker heavily depends on its construction (very light and stiff membranes) this in addition to having very low impedance and high damping amplifiers. AudioPixels’ speaker construction and digital nature can react to changes in input signal within 3 microseconds thus offering unprecedented and near perfect transient response. (For reference, the response of human hearing is of the order of 50 microseconds). As outlined, the performance specifications released not only demonstrate the previously unimaginable advantage of a 2-octave (frequency) gain when compared to similar class micro-speakers, but additionally validated the accuracy of “lifelike” tone reproduction

The guy who is mentioned in the release who reviewed the IP, Michael Klasco is the guy behind Beats/Moster headphones etc. I'm no sound engineer, but this guy is. The reason I posetd was just to get some feedback from some serious audio guys as to what they think. This is Klasco: Fans of the signature boom in Beats Electronics headphones can thank Mike Klasco, an audio-equipment consultant who was responsible for the speaker and related electronic innards of the original device. But if Apple spends $3.2 billion to acquire Beats as expected, Klasco won't be among those who reap the benefits.In 2005, he was hired by Stephen Lamar, a former hedge-fund manager who had created SLS Audio. Lamar was working with Beats owners Jimmy Iovine and Dr. Dre to create a new kind of headphone. Klasco went to work on a model that could handle the power needed for high-tech amplifier chips, which were just hitting the market.BayStar Capital, Lamar’s hedge fund, invested $12 million in SLS to create a line of audio equipment, but Lamar eventually pulled the plug on the project when he was unable to raise capital, Lamar wrote in an e-mail. The headphones seemed destined to die for good at that point, so Lamar gave Klasco permission to shop his electronic design around. He called executives at another company he was working with on other projects: Monster Cable Products, a maker of pricey audio cables.A year later, Klasco, Lamar and Robert Brunner, a former Apple designer who had done the industrial design for the headphones, met with Monster near its headquarters in Brisbane, California. When Monster finally agreed to manufacture and distribute the headphones for Beats, Klasco didn't push for a royalty or slice of ownership that might have meant millions should the Apple deal go through. Instead, he accepted a cash payment from SLS that was $10,000 less than the price he had initially quoted Lamar."All I got for our work was $30,000 and a free lunch," said Klasco. "It was a good lunch, at least: Japanese." Of course, Klasco couldn't have envisioned that Beats would help jump-start a global frenzy around premium headphones. An estimated $8.2 billion was spent on headphones worldwide last year, and Beats by Dre accounted for about a quarter of revenue, according to research firm Futuresource Consulting. Klasco's engineering shop Menlo Scientific, located in Richmond, California, has for the past 31 years helped companies build audio-related products. The firm's fingerprints can be found on the headset packaged with Microsoft's Xbox 360, a Cisco Systems desk phone situated in cubicles around the world and a monitor from Taiwan-based Acer. Klasco also worked on the AudioVision Display, an early-1990s product by Beats's prospective future owner, Apple. Sarah Joyce, a spokeswoman for Beats, declined to comment. Monster CEO Noel Lee confirmed that his company hired Klasco and Brunner work on the Beats Studio headphones.

Am I missing something here? This looks ground breaking. There is more than a billion phones sold annually, and more than 3 billion embedded devices/speakers sold in this sector alone. Given this required no amp also, sht this could be massive.

This looks too good to be true? Has anyone seriously looked at this? Sound Quality: When compared to speakers of similar surface area the sound produced is far better in every measurable parameter, including louder sound, wider frequency coverage, low distortion levels, improved transient response. This means for example, that speech will be clearer and music content richer in future iPhone devices. Simplification The chip ‘simplifies’ device audio. Semiconductor fabrication techniques are used to produce an entire loudspeaker chip (as apposed to the semi-automated subassembly process of combining magnets, cones, springs, coils etc). The chip is compatible with fully automated circuit board assembly, dramatically reducing the complexity, cost and defect rate of integrating speakers into devices. With the chip being digital, it requires no digital-to-analog conversion or amplification. It also requires no enclosure or chamber that helps reduce the size and cost of the loudspeaker and substantially simplifies the design process. The benefit of being able to just increase the number of chips to cover virtually any sound application (from the smallest of mobile devices to home theatre applications and beyond), introduces a substantive paradigm shift in the speaker market. Currently speakers are mostly design specific, thus requiring manufacturers to design, fabricate and inventory per application and per customer, whereas the ‘same chip for every application’ approach, will eliminate such costs. Energy efficiency The chip is far more energy efficient than existing speakers, which will provided major advantages for battery operated devices (iPhones), ‘green’ striving devices (such as televisions) and power stressed applications (such as the automotive sector). Ultimately the primary value proposition to industry and consumers alike is that the micro-loudspeaker chip will empower manufacturers to produce far more engaging and qualitative sound experiences, from smaller, thinner, lighter and simpler devices.

Sydney, Australia, March 3, 2015 Audio Pixels Holdings Limited, the world-leader in MEMS based digital speaker technologies, was pleased to announce today preliminary results obtained from its extensive third phase measurement program. These results not only substantiated the technology’s advantages over comparable analog speaker technologies, but exceeded the company’s own performance objectives. The results demonstrated sound pressure levels (SPL) within the low frequency spectrum that were previously believed by experts to be unattainable within a micro form factor; measuring 80dB (decibels) at 250Hz1 for a standalone chip. The performance advantage delivers a 2-octave gain when compared to micro speakers of similar size; comparable to music produced by a piano missing 24 of its keys, the two-octave achievement restores the body and depth of those missing keys. Additionally and unlike traditional micro speaker technologies, Audio Pixels chips can be cascaded in order to achieve virtually any desired performance levels. By increasing the number of chips used it becomes possible to cover virtually any application, from the smallest of mobile devices to home theater applications and beyond. The chips do not require any type of acoustic resonator or back chamber; in fact the measurements were attained using wafer level chips. These measurements validate just some of the advantages of Audio Pixels’ high performance digital speaker chips, such as low power consumption, solder reflow compliant packaging, and innovative digital drive algorithms. Following his recent “standing room only” lecture on digital speakers at the ALMA (Association of Loudspeaker Manufacturing and Acoustic) International Symposium, the company invited Michael Klasco President of Menlo Scientific, one of the worlds foremost experts in loudspeakers having his footprint on many dozens of brand name speaker and acoustic products, to review and validate the company’s technologies, methodologies and results. Mike summarized his visit as follows: This week I had the unique opportunity to visit a MEMs semiconductor lab where the Audio Pixels’ team spends their time. Having the privilege to stick my nose everywhere into this ambitious initiative, I can say that this is one committed, passionate, and competent group of individuals. This is the same sort of inspired approach and focused purpose that eventually led MEMS microphone efforts to move from an industry joke to total domination of the consumer electronics industry. The Audio Pixels sound generation technique called Digital Sound Reconstruction, differs significantly from conventional speakers in that it appears able to deliver not only higher sound levels from smaller size speaker devices, but also more extended low frequencies (down to 250 Hz for a single chip) which is crucial for wideband voice sound reproduction, an upcoming standard for phones. This is exciting and game changing stuff. My understanding is the chip will be around 10mm/12mm/2mm, fully packaged?

Technology First major innovation in audio speakers in nearly 80 years! Audio Pixels is an exciting enterprise that has developed a revolutionary technological platform for reproducing sound, thus enabling the production of an entirely new generation of speakers that will exceed the performance specifications and design demands of the world's top consumer electronics manufacturers. Our patented technologies (principle patents in national phase in 13 countries), employ entirely new techniques to generate sound waves using low cost micro-electromechanical structures (MEMS). This innovation enables the production of speaker products that deliver performance that is many orders of magnitude better than conventional speaker technologies, all in an affordable package that is roughly only one millimeter thick! Audio Pixels is the first and only known company that has successfully implemented the promise of Digital Sound Reconstruction (DSR) in a commercially feasible manner enabling a market evolution in a similar fashion to what has occurred in the transition from large, heavy, bulky analog CRT monitors, to the digital flat panel displays of today. Effective business model Audio Pixels will produce and sell a single type of chip that can be used either as a standalone speaker or cascaded in any multiples of up to 64 units of the same chip. The number of chips used in any given application is determined by the manufacturer’s desired audio specifications, based on their target end-application and target market. For example a single chip would more than suffice for a mobile phone, while a manufacturer may choose to use between 2-6 chips for a television application. This modular paradigm is entirely unique to the audio industry, which today expends significant resources designing and specifying new drivers, acoustic chambers and drive electronics for each new device. Audio Pixels innovative approach not only facilitates maximum flexibility to its customers, it further enables the Company to calibrate on the design and production on a singular product model, maximizing economies of scale, while limiting overhead associated with multiple versions of products. Pent up demand for innovation in audio speakers Driving the rationale for change and investment in audio speakers is the ever-increasing demand for smaller, thinner, clearer sounding, more power-efficient speakers. The key challenge is that for the most part conventional speaker technologies remain deeply rooted in the original voice coil inventions of Alexander Graham Bell. The inherent limitations of such speakers prohibit the delivery of quality sound in smaller packages. Audio Pixels innovation changes this paradigm. Direct and indirect market research overwhelmingly suggest that both manufacturers and consumers alike are starving for real innovation in audio speakers. The main reasons behind the demand are: - Form Factor: “Thin-is-in”; consumer preference is clearly toward esthetically pleasing devices that are thinner, smaller, lighter, and esthetically pleasing. While the industry at large has been able to shrink form factors of all other electronic devices, the last remaining barrier continues to be speakers which remain large, bulky, heavy, and extremely restrictive. Audio Pixels speakers’ shatter the barriers of sound, by providing a speaker chip that is a fraction of the size, thickness and weight of conventional speakers. - Complexity: the digital revolution has been forced to take a detour when it comes to audio speakers. Device designer’s are forced to bridge between the digital world of content and electronics, and the analog world of the speaker. Device design is severely restricted when it comes to the nebulous world of sound reproduction through speakers; a domain dominated by “sound gurus” and “golden ears” that iteratively fine tune dozens of parameters using their auditory senses rather than measured scientific methodologies. This translates into a highly restrictive design process that is long and expensive as it is complex. Audio Pixels introduces to the speaker world the de-facto standard digital component paradigm, whereby device designers address their speaker needs based on predicable component specifications. - Power Consumption: power consumption requirements are increasingly stringent in particular for embedded systems and automotive applications. The world’s ever increasing reliance on battery operated devices combined with growing environmental concerns are driving consumer and industries toward greener more power efficient devices. Conventional analog speaker drivers are perhaps the most inefficient transducer around, converting on average only 1% of their electrical energy into acoustic energy. Audio Pixels speakers are over 10 times more power efficient without compromising quality, or increasing complexity or cost; thereby delivering tangible solutions to serious problems, while presenting new opportunities. - Quality: There is an unquestionable market need for speakers that are not only far more compliant with current design trends, but that are also capable of producing high quality sound. Over the years, consumers of standalone speakers have habitually proven a willingness to pay a premium for higher fidelity sound, the same buying pattern should hold true for the endless stream of devices in which sound plays a vital role. Existing speaker technologies face manufacturers with an impossible challenge, as every attempt to shrink existing speaker technologies as to enable slim, sleek designs comes at the direct expense of the quality sound output. Audio Pixels speakers’ offers performance that is incomparable when compared to existing speaker technologies of similar size, thus for the first time, permitting manufacturers and consumers alike to benefit from choice form factors without comprising the sound quality.? What is an Audio Pixels speaker? An Audio Pixels speaker is a MEMS chip roughly 1mm thick. The chip replaces conventional speaker driver(s), enclosure or acoustic chamber, as well as the electronic circuitry associated with converting the digital signal feed to analog (via a D2A + Power Amplifier). The Audio Pixels speaker chip is not only radically smaller; it consumes a fraction of the power, to produce far better acoustic performance (clear sounding, less distorted, more accurate sound reproduction). The qualitative differences are reflected in better performance in a substantially smaller package: • Wider frequency range • Lower frequencies • Immeasurable distortion • Louder sound volume • Less power consumption Audio Pixels speakers also offer unprecedented flexibility. In sharp contrast to conventional speaker technologies where the types and number of drivers, as well as the enclosure and its electronics all must be customized and endlessly fine-tuned to a specific application; Audio Pixels offers a single chip design that is modular and perfectly predicable and linear. Given that the total number of “pixels” is the only factor determining quality, frequency and sound volume, manufacturers and device designers need only to determine the target acoustic performance and select the appropriate number of speaker chips, which are serialized using a single controller. The homogeneous construction of the chips simplifies and reduces the cost of customer design, integration, assembly and product inventory. It also permits the Company to optimize its pixels, the array, the fabrication and test processes. TECHNOLOGY Backgrounder The loudspeaker is the most variable element in an audio system responsible for most audible differences. First patented by Alexander Graham Bell as part of his telephone in 1876, the speaker, over the years has gone through a series of improvements most notably by Ernst Siemens in 1878; to the modern version of the moving coil principle invented by Chester W. Rice and Edward W. Kellog in 1924. Since, improvements in the audible performance of speakers have mostly resided in cabinet designs, acoustic suspension, materials, higher temperature adhesives, permanent magnets, precision manufacturing and so on; yet the very same fundamental principles invented some eighty years ago are still in use today! In order to understand the breakthrough of Audio Pixels technology it is important to pinpoint various mechanical and acoustic principles as they pertain to conventional, alternative, and the Audio Pixels speaker technology. A loudspeaker or speaker, is essentially an electromechanical transducer which servers to convert an electrical signal into sound (pressure waves) by moving variable volumes of air (displacement) at variable speeds. Beyond the fact that conventional speaker design did not account for today’s hi-fidelity digital sound, the fundamental limitations of conventional speaker technology is that they attempt to balance a variety of contradictory requirements needed for producing sound from an electrical signal. "Impedance matching", a term which refers to the ability of one system to efficiently convert energy from one form (electrical) to another (acoustical) is perhaps the’ most critical factor preventing conventional speaker technologies from achieving superior sound, especially when applied to smaller speakers and/or with reduced available power. Principally conventional speakers need to move a single membrane. The membrane should be very compliant, reproducing the input signal accurately. Depending on the input signal appropriate membrane movement needs to be both large and small and both fast and slow. To effectively do so, a speaker membrane should be both large and small, and both light and heavy. These opposite requirements are inherent in the design of conventional speakers. Finding the right tradeoffs is as much an art as it is a science. Further the associated speaker construction, circuitry and acoustic chamber / enclosure must also be able to support and administer such opposing requirements. In conventional speakers, the impedances of the membrane and the air are very different. The impedance mismatch of conventional speaker designs manifests itself (among others) in energy loss, limited volume and limited frequency ranges. Conventional speaker technologies force manufacturers into a complex series of compromises, none of which work in favor of today’s consumer electronics, as conventional speaker technologies do not scale down well at all, into smaller, lighter, less power consuming speakers without experiencing significant reduction performance and capabilities. At the heart of Audio Pixels technology is an innovative high impedance structure based on a high-efficiency driving mechanism which is capable of producing remarkably high air pressure despite its diminutive size. Audio Pixels revolutionary structure can produce on average roughly 10 times the pressure of a conventional speaker of the same surface area, amplitude and frequency. The acoustic principles in applying our structures to produce sound is known as “Digital Sound Reconstruction” (DSR) which principally generates the desired sound waves by using arrays of pressure generating drivers. The principles theories of DSR while envisioned decades ago had yet to be realized as a viable speaker solution. It is the clever combination of advanced fluid manipulation techniques, miniaturization technologies and the breakthrough driving mechanism of Audio Pixels that has enabled the many advantages of DSR to be realized in commercially viable manner. The end result is a speaker that literally blows away competing technologies. Design Highlights: a. Excellent impedance matching. Maximizes energy conversion (from electrical to acoustic). The theoretical efficiency limit of Audio Pixel speaker is 60%; which is roughly 60 times better than conventional speakers. The improved impedance matching also serves to significantly increase the SPL (Sound Pressure Level), or loudness, achievable from an Audio Pixels speaker when compared to conventional speakers of similar dimensions. b. True digital reproduction of sound using a large array of identical micro-speakers. Unlike conventional speakers in which the membrane is required to compliantly travel varying distances and speeds all the micro-speakers are required to perform the exact same simple function, i.e. work or don’t work at any given time. When working, they travel at the same speed over the same displacement. c. DSR offers performances that are orders of magnitude better than conventional speakers of similar sizes. The frequency range can be much broader and the frequency response perfectly flat. The distortion level is a fraction of that of conventional speakers, in most cases, well below the human detection threshold. d. Low Power Requirement – the driving mechanism uses a tiny fraction of the power required by conventional speakers resembling the power requirements of headphones. e. Design flexibility – not only are the speaker “drivers” very thin, they require no cabinet or enclosure and therefore can be mounted on most any surface (including SMD configurations), providing device designers with unprecedented flexibility. Principle of Operation The sound pressure generated by an Audio Pixels speaker is proportional to the number of operating micro-speakers (“Audio Pixels”) and the throughput of each one. Varying the number of pulses over time produces different frequencies. Unlike analog speakers, individual micro-speakers operate in a non-linear region to maximize dynamic range while still being able to produce low frequency sounds. The net linearity of the array comes from linearity of the acoustic wave equation and uniformity between individual speakers. The overall non-linear components in the generated sound wave have a direct relation to the number of micro-speakers in the device. Additional Advantages over Conventional Speakers Damping: Conventional speakers oscillate long after the input signal is stopped. The heavy membrane transfers only a fraction of its energy into the air and it continues to oscillate for a considerable time before the oscillations decays. Conventional speaker systems utilize artificial damping to overcome this problem. The most common damping mechanism leverages the amplifier to absorb large opposite currents induced in the voice coil of the speaker due to its movement. The excess currents require sophisticated amplifier designs. In contrast, an Audio Pixels speaker "stops on a dime". The signal is initiated and terminated within one clock cycle. Vibrations: Due to the high impedance matching of Audio Pixels speakers, a much smaller movement is required to generate the same loudness. According to Newton's law, each action generates an opposite reaction. In a speaker, movement of the membrane generates opposite movement of the frame. The smaller movement of an Audio Pixels speaker generates significantly lower vibration levels. Vibrations are often problematic in sensitive electronics. In displays for example, excess vibrations produced by speakers can cause deformation of the image and potentially damage the display elements. Vibrations are also problematic in full duplex communication devices (such as mobile phones or blue-tooth headsets), where the microphone can pick up the speaker vibrations generating echo and feedback noise. The reduced vibrations of an Audio Pixels speaker allow much more moderate levels of echo reduction and suppression. Directivity Control: Audio Pixels invented (and patented) a scheme of controlling the acoustic directivity pattern of its speakers. The scheme is similar in nature to other phase-array devices, most well known are radars and RF antennas. The same speaker can be used as an omni-directional sound source (much like conventional speakers), or a unidirectional source (a narrow beam of sound is projected in one directions, and almost no sound is projected in any other direction), or a multi-directional source projecting several sound beams (each may carry different audio), in several different directions. The applications leveraging control of sound directionality are limitless

Audio Pixels Holdings Limited (AKP:ASX; OTC:ADPXY) is pleased to announce that it has signed a Joint Development Agreement with Sony Corporation of Japan for the development of its patented low cost micro-electro mechanical (“MEMS”) digital speakers. Sony Corporation is one of the world’s foremost consumer electronic and semiconductor conglomerates. As previously announced the joint development partner, Sony Corporation is funding the majority of the rather substantial costs associated with transitioning the technology into a mass-manufacturable product. Sony delivered the first batch of phase-one development chips for testing to Audio Pixels in Israel on 17 June 2011. The Joint Development Agreement with Sony anticipates that once the Development Phase and testing has been completed that the parties will enter into a formal Commercial License Agreement. Audio Pixels and Sony are well down the track of the agreed development plan to achieve mass-production capabilities, after which Sony intends to transition to becoming a mass-manufacturing partner primarily focused on supplying product for the myriad of diverse consumer products that Sony already produces and sells globally and a supplier of speaker products for use throughout the myriad of diverse consumer electronics products produced and sold worldwide.

5/7/11, RELEASE TO THE ASX Sony has signed a joint development agreement with Australian audio technology company Audio Pixels Holdings. The deal will see Sony funding the lion's share of costs associated with turning Audio Pixels' technology patents into a mass-manufacturable product. ASX listed Audio Pixels chairman Fred Bart said the he anticipated that once the development phase and testing has been completed, "the parties will enter into a formal commercial licence agreement". Audio Pixels Holdings owns 100 per cent of Audio Pixels Limited, an unlisted Israeli corporation which developed the technological platform for reproducing sound which enables the production of a new generation of speakers that can be used in products for mobile phones, televisions or stereo systems.
