How MEMS Speaker Tech Is Changing Earphones

AI-generated, human-reviewed.

The latest development in earphone speaker technology is MEMS (Micro-electro-mechanical-systems) transducers. On Home Theater Geeks, Scott Wilkinson learns from Moti Margalit of SonicEdge why MEMS speakers enable earphones to be smaller, more comfortable, and offer improved sound—overcoming limitations of traditional designs.

Why MEMS Speaker Technology Matters

Traditional speakers, even in tiny earphones, haven't changed much for over a century. As Moti Margalit explains, squeezing great sound into smaller spaces is physically difficult with the old technology, especially for the low (bass) and high (treble) frequencies.

MEMS speaker technology uses micro-scale silicon membranes and ultrasonic modulation, which allows much smaller drivers to deliver impressive, full-range sound. This is excellent news for anyone who finds standard earbuds uncomfortable, lacks audio clarity, or wants a better listening experience on the go.

How SonicEdge’s MEMS Speakers Work

The new design from SonicEdge uses ultrasound generation—meaning these tiny speakers create vibrations above what humans can hear (400,000 Hz). These ultrasonic waves are then "modulated" back into audible sound by a clever mechanical system inside the chip.

MEMS microphones have been standard in phones for years, but turning MEMS into high-quality speakers was always a technical challenge. SonicEdge’s breakthrough is in their “ultrasonic pump” design: instead of directly pushing air like a large speaker cone, their chip moves air efficiently at high speeds, transforming those movements into clear audio.

What Makes MEMS Earphone Speakers Different?

Smaller size: MEMS speakers are much smaller than classic drivers. This allows for thinner, lighter, and better-fitting earphones that don’t sacrifice audio range.

Improved comfort: Because they’re so small, earphones can be shaped more naturally for the ear canal—solving a common complaint that current earbuds are simply too bulky.

Full-range sound: SonicEdge’s MEMS speaker can reproduce both the deep lows and sparkling highs typically missing from earphones, thanks to their wider frequency response.

No vibration issues: Traditional speakers can create unwanted vibrations; MEMS chips minimize these, resulting in clearer music and easier assembly for manufacturers.

Consistent manufacturing: Produced in silicon fabs (the same as computer chips), MEMS speakers have extremely consistent quality and scale easily.

Safe ultrasonic operation: Some listeners worry about ultrasound exposure, but SonicEdge works far above problematic ranges (400 kHz vs. the 20-100 kHz sometimes flagged in safety research). Plus, standard earphone meshes block any ultrasound that escapes—without impacting sound quality.

Who Should Care?

• Music lovers seeking high-resolution audio in a compact form
• Hearing aid users or anyone needing tiny, high-performance speakers
• Anyone frustrated with uncomfortable earbuds

When Will MEMS Earphones Be Available?

According to Moti Margalit, the first MEMS-equipped earphones should hit the market in late 2027. SonicEdge is scaling up through partnerships with big semiconductor manufacturers and “earphone brains” chip designers to integrate MEMS into complete products.

For now, if you're shopping, note that the technology is indeed coming and is worth watching if you’re planning an audio upgrade.

What You Need to ReMEMSber

MEMS speaker technology represents a significant leap in earphone design:

• Expect future earphones to fit better, sound fuller, and deliver enhancements like improved noise cancellation and less leakage between speaker and microphones (useful for clarity and ANC performance).
• Concerns over ultrasound exposure are largely unfounded with these designs, thanks to their operating ranges and standard acoustic meshes.
• The consistent, scalable nature of MEMS production means you can expect more reliable performance between individual earphones and fewer manufacturing defects.

If you’ve been waiting for an earphone revolution, whether for comfort, fidelity, or new features, MEMS speakers are the technology to watch. Scott Wilkinson’s deep dive with SonicEdge’s CEO offers a glimpse into why your next set of earbuds may finally tick every box.
