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.
Claims7
A dual-mode true wireless device having a normal mode and a directional-speaker mode comprising:
- a modulator;
- and
- a microelectromechanical system (MEMS) speaker coupled to the modulator, wherein the MEMS speaker has an audio frequency band and an ultrasonic frequency band,
- wherein the modulator does not generate ultrasonic waves in the normal mode, and the modulator generates ultrasonic waves in the directional-speaker mode.
