USound’s silicon MEMS microspeakers with their compact size of 4.7 × 6.7 × 1.6 mm are ideal for in-ear headphone designs, wearables such as audio glasses. MEMS speakers offers maximum flexibility for outstanding designs approaches. Additionally, thanks to their wide bandwidth, it enables high-res audio applications.
The round MEMS speaker is USound’s next-generation micro 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).
Danube: audio module for audio glasses
The Danube 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.
Danube 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.
Dione: sound stripe
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.
Proteus 1.0 kit
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 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 ear bud design.
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 which allows real-time 3D sound.
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 is our common application platform for evaluating rapid prototyping and designing audio solutions using USound devices. The board includes Digital Signal Processor, DAC, and Amplfiers. It is compatible with Raspberry Pi, Arduino and the ST nucleo board.
Smart audio amplifier
Leda UC-P2120 is a power-efficient smart audio amplifier designed specifically for MEMS speaker-based audio systems. Compared to out-of-the-shelf amplifiers, it reduces the number of external components needed, thus providing more space for other functionalities, and optimises the overall power consumption. Leda has a digital I2S interface and configurable filter functions. Leda and our MEMS speakers are the perfect basis for a tiny yet high-performance audio module.
