Ganymede series MEMS speakers

The MEMS speakers from the Ganymede series are ideal for creating MRI-compatible headphones, true wireless (TWS) earphones, as well as wearables such as audio and AR/VR glasses.

Thin form factor

With a thin form factor of 1.6 mm, MEMS speakers from the Ganymede series offer unmatched audio quality and enable the production of lightweight and ergonomic devices.

Hi-Res audio

Ganymede MEMS speakers provide natural and precise audio output up to 40 kHz. The speakers create a crisp and vivid soundscape, enabling customers to design the most immersive audio devices.

No magnets

Ganymede is the only speaker series on the market with no ferromagnetic materials. They are the ideal solution for MRI-compatible headphones and EMI-sensitive applications.

Reliability and repeatability

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

Design MRI-safe headphones

USound’s Ganymede series is perfect for designing MRI-safe headphones.

Our MEMS speaker UT-P2016, which contains no ferromagnetic materials, can be uniquely used in environments with high magnetic field strength, such as MRI scanners.

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.
