SonicEdge is a breakthrough in speaker design. Instead of using heavy, vibrating parts to create sound, it uses ultrasonic waves to move air more efficiently. The result: high-quality sound from a speaker that’s a fraction of the size of today’s options. Traditional speakers rely on mechanical membrane vibration at audio frequencies, creating inherent trade–offs between size, performance, and acoustic efficiency that constrain miniaturization efforts. SonicEdge addresses these limitations by creating an ultrasonic air pump working at hundreds of KHz effectively replacing slow mechanical pumping with efficient ultrasonic air movement.
The core innovation enables speakers that are ten times smaller than conventional alternatives while maintaining superior sound quality. Unlike traditional transducers that require complex spring-mass modeling with frequency-dependent responses, SonicEdge operates as a constant volume velocity source, eliminating sensitivity to external acoustic loads and mechanical vibration issues. The system requires only sub-micron membrane displacements, making it ideally suited for MEMS implementation using electrostatic actuation.
