MEMS Loudspeakers
With their compact size, our MEMS loudspeakers are ideal for sophisticated earphone and headphone designs and modern wearables such as true-wireless headsets. Producing a crisp and vivid soundscape, they offer a yet unmatched accuracy of sound. Due to their small form factor, USound MEMS speakers will be important for spatial audio applications such as smart-home loudspeakers with variable directivity, or cue preserving 3D headphones.
Features
High-res bandwidth
Hi-Res bandwidth can be achieved with a single MEMS speaker.
Seamless integration
Easy integration into modern audio systems and MEMS microphones. It is also capable of operating as a piezo microphone.
Enables innovative IDs
MEMS speakers enable modern lightweight and ergonomic designs for wired earphones and TWS.
Unmatched sound quality
MEMS speakers produce clear and vibrant sound immersing the listener into their audio environment.
Ganymede series
ADAP
MEMS speakers for wearables and high-res audio
Adap MEMS speakers are ideal for free-field audio solutions such as wearables. Thanks to its small size and low weight, Adap offers maximum flexibility for outstanding designs approaches. Providing a wide bandwidth, it enables high-res audio applications. Adap produces tangible, clear and rich sound, immersing the listener into their personal audio environment.
Achelous
MEMS speakers for hearables
Achelous MEMS speakers are ideal for in-ear audio solutions such as wired earphones or true wireless systems (TWS). Thanks to its small size and low weight, Achelous, offers maximum flexibility for outstanding design approaches. Achelous produces vivid, clear and rich sound, immersing the listener into their personal audio environment.
Conamara
The round MEMS speaker is USound’s second generation MEMS loudspeaker. Conamara is IPx8 waterproof with a highly competitive SPL and THD, making it the ideal choice for in-ear audio solutions such as wired earphones or true wireless systems (TWS).
Evaluation and development boards
Amalthea UA-R3010
Amalthea is a linear amplifier for piezoelectric speakers. Its frequency range goes up to 80kHz, and it can drive up to 40 Ganymede at once. Amalthea can be used with Carme, a speaker box designed to hold a USound’s Ganymede speakers. It is used to conveniently test the speaker’s performance.
Helike UA-E3010
Helike is our common application platform for evaluating rapid prototyping and designing audio solutions using USound devices. The board includes Digital Signal Processor, DAC, and Amplifiers. It is compatible with Raspberry Pi, Arduino and the ST nucleo board.

Acoustic privacy in audio glasses: how to make sure another person doesn’t overhear the user’s phone calls
The aim of this article is to discuss the topic of acoustic privacy in audio applications, specifically in audio glasses. With earphones, this obviously becomes trivial: intra-aural earphones seal the loudspeaker into the ear canal by means of the silicon tip, which naturally offers high isolation. Intra-concha earphones do not have a sealed front volume,…

How to measure USound MEMS loudspeakers
USound currently offers two MEMS loudspeakers that are part of the Ganymede series: Adap UT-P2019 and Achelous UT-P2018. Adap is optimized towards maximum acceleration, making it ideal for free-field applications, whereas Achelous is optimized towards maximum excursion, making it especially suitable for occluded-ear applications. Therefore, USound MEMS loudspeakers can be evaluated in both acoustic domains:…
