Ganymede series MEMS speakers

The MEMS speakers from the Ganymede series are ideal for designing modern earphones and headphone designs as well as wearables such as audio glasses and AR/VR glasses.

Thin form factor

With a thin form factor of 1.6 mm, MEMS speakers from the Ganymede series produce above-class audio quality and enable lightweight, ergonomic hearables and wearables.

Hi-Res audio

USound MEMS speakers provide natural and precise audio output, making them the best choice for earphones, headphones, augmented reality glasses, audio glasses, and virtual reality glasses.

No magnets

USound MEMS speakers are the only loudspeaker on the market with no ferromagnetic materials. Achelous UT-P2016 is the ideal microspeaker for manufacturing MRI-compatible headphones and earbuds.

Reliability and repeatability

USound MEMS speakers enable a fully automated manufacturing process, and the part-to-part variation is the lowest in the audio industry. USound MEMS speakers comply with international reliability standards to ensure robustness and stable performance over the product lifetime.

Design premium quality earphones

Due to its unmatched sound quality and thin form factor, USound’s MEMS speakers are the ideal loudspeakers to take hearables to the next level. Full bandwidth can be achieved with a single MEMS speaker, reaching precise natural sound and resulting in an outstanding listening experience.

Design lightweight and modern wearables

USound’s MEMS speakers are perfect to miniaturize devices with high component density, such as AR/VR glasses and audio glasses.

Due to the thin form factor of the MEMS loudspeaker, an ergonomic and slim audio temple can be designed without compromising sound quality. With USound MEMS speakers, glasses can also be enhanced with natural and appealing sound and protected from audio leakage by using USound’s patented dipole solution.
