"The world's smallest acoustic amplifier"

[TobyJ]

I thought this sounded interesting, and I wondered whether it has any relevance to the audiophile amplification world.

Caveat: what I know about engineering would fit on the back of no envelopes, so forgive me if this is either old news, or totally irrelevant.

Much too small and probably much too cheap so probably not for the common audiophiles/audiophooles.
But here in ASR where people are interested in real science and engineering it sounds very interesting, so thanks for sharing.

Coming soon to an MQA white paper...
