Wireless audio technology has made significant progress, but it still falls short of the quality offered by wired audio. However, advancements in the field are bringing us closer to bridging that gap. One such innovation is ultrasound technology.

Audio technology company xMEMS has introduced their latest solid-state speaker, Cypress, which utilizes ultrasound to push the boundaries of audio reproduction. Unlike the previous Cowell model, the Cypress speaker incorporates ultrasonic amplitude modulation transduction. Even in its prototype stage, the Cypress speaker demonstrated superior audio quality compared to other popular earbuds.

The main advantage of the Cypress speaker is its use of ultrasonic waves to achieve more accurate audio reproduction. Ultrasound expands the range of sound reproduction beyond what is possible with traditional speakers. xMEMS boasts that these speakers offer an “exact acoustic copy” of the original sound.

In addition to high-quality audio reproduction, the Cypress speaker also promises impressive active noise cancellation capabilities. It can produce sound pressure levels exceeding 140dB, surpassing mainstream products currently available. This results in significantly enhanced ANC performance, capable of canceling out loud noises such as construction work or a crying baby.

Despite its advanced features, the Cypress speaker comes in a compact 6.3 x 6.5 x 1.65mm package. This allows manufacturers to create lighter and more feature-packed earbuds or incorporate the speaker into existing form factors. However, it remains uncertain how manufacturers will utilize this technology. xMEMS anticipates that mass production of the Cypress speaker will begin in late 2024.

With the introduction of ultrasound technology, wireless audio is poised to reach new heights in terms of audio quality and noise cancellation. xMEMS is at the forefront of this innovation, revolutionizing the future of audio technology.
