As quick because the world of audio is growing, all of our headphones nonetheless use bodily amplifiers to generate sound which is then pushed in opposition to a diaphragm and into our ears. This method traces its beginnings to over 100 years in the past however at present xMEMS Labs is providing another with their Cypress ultrasonic solid-state speaker for TWS earbuds. These audio system ditch the bodily amplifiers and as a substitute depend on ultrasonic sound pulses that are usually imperceptible to human listening to.
The important thing growth made by xMEMS is the corporate’s ultrasonic amplitude modulation transduction. The speaker can generate ultrasonic sound pulses that are then pushed to a demodulator to rework the sound pulses into audible sound for the consumer. Ultrasonic pulses provide an actual acoustic copy of their supply sign which ought to translate to superior audio replica throughout all sound frequencies. Cypress ultrasound audio system are claimed to supply higher high quality and extra detailed sound in comparison with coil audio system whereas nonetheless supporting hi-res and spatial audio.
Every Cypress MEMS speaker suits in a tiny 6.3 x 6.5 x 1.65mm bundle and must also provide louder and deeper bass than standard audio system. The corporate claims its new ultrasound speaker can produce 140dB low-frequency sound strain stage (SPL) and go as little as 20Hz. One other benefit is the broader ANC bandwidth permitting earbuds with Cypress MEMS audio system to drown out extra undesirable larger frequency noises round you. The brand new audio system are additionally touted to supply decrease latency because of their fixed electrical-to-acoustic conversion time.
The Cypress ultrasonic audio system from xMEMS will likely be demonstrated at CES 2024 whereas mass manufacturing is predicted to begin in late 2024. The corporate didn’t share any pricing particulars simply but however it did reveal it has reached a producing partnership with TSMC which can make them cost-competitive with mass-market audio system for wi-fi headphones and earbuds.
