MEMS Speakers for True Wireless Stereo (TWS) Earphones

Due to their small factor and precise sound, USound MEMS speakers can be used in a number of applications, including true wireless stereo (TWS) devices. As the name suggests, “true wireless stereo” is the technology used for developing wireless audio devices, such as Bluetooth® earphones. TWS devices can be connected to a device without the use of cables, improving the overall user experience.

TWS earphones have been dominating the market since the launch of the Apple AirPods in 2016. With various wireless earbuds entering the market, manufacturers of TWS audio devices need to differentiate themselves from their competitors. Users desire wireless earphones that are sleek in design, but also competitive in audio clarity and precision. By pairing excellent audio perfomance with miniaturized, USound speakers are the ideal solution to meet customer demands.

MEMS Speaker Applications

Thanks to their compact form, integration flexibility, robustness, and sound precision, USound’s microspeakers can benefit the design and production of:

True Wireless Systems (TWS) earphones

Augmented Reality & Virtual Reality Glasses and Headsets

Audio glasses


Magnetic Resonance Imaging (MRI) Headphones and Medical Devices

Over-the-counter (OTC) hearing aids

TWS Components

There are several TWS components that are necessary to produce wireless earphones. Microspeakers are one of the main TWS components in high demand. MEMS speakers, in particular, are the ideal solution, as they enable manufacturers to improve the ergonomics, sound quality, and noise-canceling function of their wireless earphones, among other benefits.
