THD 81 SONIC EDGE A PURE DIGITAL MEMS SPEAKER

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market.

In episode 81, Sonic Emotion's CTO and CEO join to explain their MEMs speaker technology. Conventional speakers require a balance between mechanical, acoustical, and electrical resonances. As a speaker shrinks in size, keeping the resonance balanced is a complex challenge and the quality of sound is compromised.

We have developed a unique technology that, instead of attempting to solve the problem, actually turns it on its head. Our unique technology generates ultrasound from multiple speakers, each as wide as a strand of hair, and then transforms the ultrasound to sound using a patented acoustic-mechanical frequency transformer.

The ultrasound speakers and frequency transformers are realized as solid-state MEMS devices. The MEMS device is manufactured using semiconductor technologies leveraging the semiconductor ecosystem for scalability and price trajectory. The outcome is clear: maximum sound quality in minimal size.
