Startup uses MEMS ultrasound to improve audio speaker

SonicEdge Ltd. (Binyamina, Israel), founded in November 2018, is developing an ultrasound-based MEMS audio speaker.

This is claimed to provide enhanced audio in small form factors at both low and high frequencies and extended operation to 20KHz and beyond. Applications for the ultrasound system is therefore the ‘usual suspects’ of hearables – ear buds, augmented and virtual reality headsets and glasses, headphones and heading aids.

Other claimed advantages of SonicEdge speakers include smaller size, no vibrations, reduced size of back cavity. The company is aiming initially at the True Wireless System (TWS) headphone/earbud market, where the SonicEdge speakers cold enable smaller and better sounding earphones.
