Hi-Res bandwidth can be achieved with a single MEMS speaker.
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.
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.
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 persona audio environment.
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).
Evaluation and development boards
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 Amplifiers. It is compatible with Raspberry Pi, Arduino and the ST nucleo board.
To speed up the process of bringing your concept of a MEMS speakers-based audio system to reality, we designed two development platforms: Amalthea UA-R3010 and Helike UA-E3010. This article will walk you through the essentials of rapid prototyping with MEMS speakers and provide an overview of the expansion kits available. If your goal is to…
Most consumer electronics nowadays use traditional electrodynamic speakers. They consist of a magnet, a voice coil, a diaphragm and a support structure/enclosure. This working principle limits the minimum height that can be achieved with such a loudspeaker. The diaphragm’s suspension solely controls the mechanical behaviour, as electrodynamic microspeakers typically lack the centering spider of larger…
One of the significant advantages of MEMS speakers is the possibility to be easily integrated into a wide variety of products. Due to the very small form factor, MEMS speakers can be used in technologies requiring more minimal designs, such as TWS, audio glasses and ultrasound applications. This article will go through some essential aspects…
In this article, I want to focus on one particular feature that we haven’t discussed: our extreme bandwidth technology (XBW). We use our XBW (extreme bandwidth) technology to increase the range of sounds that the loudspeaker can reproduce. Our Ganymede MEMS speakers can play higher frequencies than conventional loudspeakers and produces higher SPL at ultra-high…
