USound GmbH’s Ganymede Achelous and Adap MEMS speakers with their compact size of 4.7 mm x 6.7 mm x 1.6 mm are ideal for in-ear headphone designs and wearables such as true-wireless headsets. The perfect addition to traditional speakers, they can be easily retrofitted into standard enclosures to improve treble or implement 3D audio systems.
Achelous is a MEMS speaker designed for occluded-ear headphones. It can also be used as a micro-tweeter for wearables and array applications. This speaker provides higher excursion and more damping ideal for in-ear designs. In free-field, the resonance is lower than Adap, which allows a lower crossover frequency.
Adap is a MEMS-based micro-speaker for occluded-ear headphones and can also be used as micro-tweeter for wearables and array applications. It is optimized as a tweeter with high SPL above resonance. The Adap has a higher resonance frequency.
