Abstract
A true wireless device is provided. The true wireless device includes a modulator for generating ultrasonic waves and a MEMS speaker coupled to the modulator. The MEMS speaker provides greater bandwidth than traditional speakers such as electrodynamic speakers and piezoelectric thin-film speakers. In particular, the MEMS speaker has an audio frequency band and an ultrasonic frequency band.
