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
Conamara is an IPx8-waterproof MEMS speaker with a highly competitive SPL and THD. It’s the ideal choice for in-ear audio solutions for 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.

World Hearing Day 2022: To hear for life, listen with care
More than 1 billion young people (12-35 years old) are at risk for hearing loss due to recreational exposure to loud sounds. To raise awareness for the implications of hearing loss due to unsafe contact with high volumes and continued exposure, the World Health Organization (WHO) has established the World Hearing Day on March 3rd.…

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,…

Whitepaper: Active Linearization Algorithm for USound MEMS Speakers
Low distortion at high SPL are the main requests every acoustical engineer has on every audio product; this is especially true for miniature speakers where size is limited. USound MEMS speakers are not immune to this area of conflict. This whitepaper describes the Active Linearization Algorithm (ALA), a signal processing method of improving USound MEMS…
