MEMS speakers

Adap MEMS speaker with tweezers and audio glasses

Adap MEMS speaker

Adap, from the Ganymede series, is designed for innovative wearables such as audio glasses and AR/VR glasses, as well as smart speakers with Hi-Res audio. Thanks to its best-in-class ratio between acoustic performance and form factor, Adap offers maximum flexibility for unique design approaches.

Achelous MEMS speaker with earbuds megaclite

Achelous MEMS speaker

USound’s silicon MEMS microspeakers, with their compact size of 4.7 × 6.7 × 1.6 mm, are ideal for in-ear headphone designs, and wearables such as audio glasses. MEMS speakers offer maximum flexibility for outstanding design approaches. Additionally, thanks to their wide bandwidth, it enables high-res audio applications.

Conamara MEMS speaker with tweezers and wireless earbuds

Conamara MEMS speaker

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).

Wearables

Danube UAM-P2050

The Danube UAM-P2050 audio module provides the best-in-class ratio between great audio performance and the ideal mechanical characteristics to design high-end audio glasses and AR/VR glasses.

Fauna audio eyewear produces vivid sound - powered by USound MEMS technology.

Danube UAM-P2050 use case: Fauna audio glasses

Fauna audio glasses are powered by USound’s MEMS audio module Danube – in a lightweight, elegant design. With our two-way audio system integrated into each temple, Fauna produces vivid sound for music, audiobooks, and phone calls.

Speakers array

Dione Maxi UY-R3020

The Dione sound stripe consists of 20 Adap MEMS speakers. Due to its flexible structure and protective construction, it is ideal for applications where audio is added on top of an existing design.

MEMS speaker array kit

Proteus 1.0 UY-E2010

Proteus is a design for a powerful speaker array based on our Ganymede MEMS microspeakers — with 40 or 80 speakers inside.

Earphones and 3D audio solutions

Megaclite 4.0 UH-R2040

Megaclite is a pair of wired USB-C earphones based on our MEMS speaker Achelous, delivering a distinctive sound quality that differentiates from balanced armature and electrodynamic earphone designs. Bass response is clean and strong – all with an innovative, comfortable earbud design.

Taygete UY-R1040

This novel 3D headphone design enables authentic 3D sound thanks to the bridge of 16 MEMS micro speakers and an electrodynamic woofer in each cup. It also includes a unique algorithm that allows real-time 3D sound.

Evaluation kits

USound's Amalthea and Carme, an amplifier with speaker box for evalution purposes

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.

MEMS speakers evaluation board helike

Helike UA-E3010

Helike UA-E3010 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.
