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.
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.
