Ultra-Compact 3.5 mm Planar Magnetic MEMS Speakers Bring Hi-Fi Performance to Next-Generation TWS Earphones
SUNNYVALE, CA, UNITED STATES, January 13, 2026 /EINPresswire.com/ — Otowahr, a technology leader in MEMS (Micro-Electro-Mechanical Systems) speaker innovation, today announced the Otowahr Lark™ micro speaker family, a new generation of planar-magnetic MEMS speakers designed for high-quality True Wireless Stereo (TWS) and wired earphones.
Powered by Otowahr’s proprietary TrueSound© planar-magnetic MEMS technology, the Lark family delivers exceptional clarity, fast transient response, and Hi-Fi sound quality in an ultra-compact 3.5 mm diameter form factor—addressing long-standing performance and integration challenges in in-ear audio design.
Two Models for Distinct Listening Experiences
The Otowahr Lark family includes two models tailored to different listening preferences and product requirements:
Otowahr Lark™
Designed for balanced, full-range performance, Otowahr Lark is ideal for both wired and wireless earphones. Its low-profile, compact design enables deeper in-ear placement, improving comfort, stability, and acoustic accuracy—especially for all-day wear and active use.
Otowahr Lark™ Alto
Optimized for extended high-frequency performance, Otowahr Lark Alto targets wired earphones and audiophile-grade listening, particularly for classical and acoustic music. When paired with a simple bass driver—without requiring a crossover circuit—it delivers a coherent full-range sound signature suitable for a wide range of listener preferences and product designs.
Breakthrough Planar Magnetic MEMS Architecture
Otowahr’s electro-magnetic MEMS micro speaker represents a fundamental departure from conventional dynamic drivers. Key innovations include:
• A carefully selected planar membrane material combined with a unique magnet-coil arrangement to improve acoustic efficiency while reducing overall size
• An elastic planar diaphragm structure that preserves low-frequency performance despite its miniature form factor
• A monolithic semiconductor-based design that enhances dimensional precision, driver matching, manufacturability, and production scalability
Designed for Efficient System Integration
Otowahr Lark micro speakers are engineered to simplify earphone design and accelerate time-to-market:
• Flat impedance across the full frequency range, enabling easier impedance matching and lower power consumption
• Dipole acoustic architecture, producing symmetrical sound radiation on both sides of the diaphragm
• SMT-friendly construction, reducing manual assembly compared with traditional dynamic drivers
• Ultra-small footprint, providing maximum flexibility for industrial designers to tailor products for different audiences and use cases
Product Highlights
Otowahr Lark™
• Planar-magnetic MEMS micro speaker
• Compact, low-profile design for in-ear earphones
