  • Our tech is simply not there to put proper speakers and microphones AND a well sized battery in something so small.

    Especially speakers. Volume is determined by the amount of air the diaphragm can move - and there’s an exponential relationship between the size of the diaphragm and the volume of air it moves. Large diaphragm: even small movements (low amplification) can be loud because of how much air you move. Small diaphragm: even at high amplification, the volume will be low.

    Smartphone speakers work this around by having an actually large speaker with appropriate sized cavity tucked away. Like, look at an iPhone teardown and see just how big the speakers are for the mediocre volume they can output. A combadge is what, 1/5 the size of the largest iPhone, in volume? And you still need to put electronics AND a battery in there.

    It could work as a microphone, but not as a speaker.
