Conamara 6mm Tweeter with earbuds

Conamara series MEMS speakers

Conamara series MEMS speakers were specifically developed for miniaturized audio devices such as true wireless earphones (TWS) and hearing aids. Conamara MEMS speakers are available as full-range speakers and as a tweeter, following market demand for high-performing two-way systems. Conamara delivers exceptional audio fulfilling Hi-Res audio requirements. Thanks to USound’s patented MEMS technology, MEMS speakers from the Conamara series are the thinnest speaker available on the market.

For advanced TWS

The Conamara MEMS speakers’ tweeters deliver outstanding audio performance in the high-frequency range and have a thin form factor freeing volume for other components and offering higher design flexibility.

Integration Flexibility

The ultra-thin Conamara MEMS speakers, combined with SMT reflow soldering capabilities, enable an automatic pick and place assembly process reducing production costs.

High-res bandwidth

Exceeding market demand, the Conamara speakers deliver above-class audio performance fulfilling Hi-Res audio requirements with a bandwidth up to 40 kHz.

IPX8 certified

Conamara MEMS speakers can be safely submerged up to 3 meters for about 30 minutes reaching water-resistant capabilities (IPX8), therefore reducing the complexity of manufacturing waterproof consumer electronics and opening new application possibilities.

Spatial audio

Due to USound’s MEMS speakers extended bandwidth, small form factor, and accuracy, spatial audio can be easily implemented in true wireless stereo earbuds.

The thinnest high-performing microspeaker on the market

Save space with the thinnest microspeaker. USound MEMS speakers from the Conamara series outperform ED and BA speakers with higher SPL at a smaller volume, weight, and thickness. Unlike voice coil speakers, Conamara is IPX8 water-resistant, making waterproof products easier to manufacture. Additionally, these MEMS microspeakers are SMT reflow compatible, enabling fully automatic assembly of audio products to achieve the highest quality and performance.

Best-in-class ratio between acoustic performance and thickness

USound’s cutting-edge MEMS speakers’ technology fulfills Hi-Res bandwidth requirements by reaching up to 40 kHz. This technical innovation makes Conamara MEMS speakers the ideal loudspeakers for high-performing consumer electronics products, where superb audio accuracy and Hi-Res audio are desired.

Engineered for innovative 2-way True Wireless Earbuds

USound’s Conamara MEMS speakers are the thinnest microspeaker on the market. It enables miniaturization and modularization, saving space for other sensors and components, enhancing any TWS design with add-on features, and allowing maximum flexibility for bolder industrial design.

Hearing aids USound

Design smart hearing aids

Smart hearing aids are the most popular treatment for hearing loss due to the myriad of functionalities it offers the end user. The ultra-thin form factor of the Conamara series speaker enables designing miniature OTC hearing aids with biosensors, longer battery life, and top ergonomics and discretion. Thanks to their extended high-frequency bandwidth, the Conamara MEMS speakers provide the desired natural and clear sound in hearing aids.
