The second prototype had a cousin. It was much smaller, and used only 1 transducer. Although I did not end up developing it further, it is still worthy of sharing. I was thinking small, and using AAA batteries instead of a rechargeable alternative, I saw this living on someones nightstand or desk. A bit of a novelty, as the sound quality suffered with its size. There were however, some intriguing ideas at play. An integrated phone holder that doubled as a cord wrap. Maybe I will revisit this someday.
