I just stumbled on this thread that started nearly 6 years ago.
The current state of this development is that Audio Pixels have announced:
- they have a speaker chip and driver asic that is nearly production ready
- they have signed 50 non-disclosure agreements with leading industry players
- there will be private demonstrations to industry in the next few months
- just this week it has entered into an agreement with TowerJazz to mass produce the speaker chip
- there has been no public demonstration yet
The share price (in AUD) has gone up from $0.20 to $33.00
