Conamara series MEMS speakers

Conamara MEMS speaker series was developed with miniaturized audio devices such as true wireless earphones (TWS) and over-the-counter (OTC) hearing aids in mind. Conamara series includes full-range speakers and tweeters, following the market demand for high-performing, compact single-driver and two-way systems. The speakers deliver exceptional performance over the audible range, fulfilling Hi-Res requirements and pushing the boundaries for wideband ultrasonic applications.

COMPACT FORM FACTOR

Conamara MEMS speakers have an ultra-slim round form factor, maximizing integration flexibility and space efficiency for unlimited design possibilities.

REFLOW SOLDERING COMPATIBILITY

The micro speakers are reflow soldering compatible, enabling an SMT automatic pick-and-place assembly process. This increases overall quality and time efficiency while reducing production costs.

Hi-Res audio

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

IPX8 certified

Conamara MEMS speakers fulfill IPX8 requirements, reaching full waterproof capabilities. This reduces the complexity of manufacturing water-resistant products, while opening new application possibilities.

Ultrasonic performance

USound’s Conamara speakers offer a flat response throughout the ultrasound frequency range up to 80 kHz for wideband ultrasonic applications, opening new avenues in signal modulation for consumer electronics and industrial devices.

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 the design of miniature OTC hearing aids with biosensors, longer battery life, 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.
