The 'Otowahr TrueSound©️ MEMS' speaker is a newly introduced component for wireless earbuds. Featuring an electromagnetic planar magnetic driver scaled down to an exceptionally small 3.5-millimeter diameter, the core innovation of this technology is the adaptation of planar magnetic transducer principles — typically associated with large, high-fidelity headphones — into a micro-electro-mechanical system (MEMS) format suitable for miniature wearable audio devices.
The design of the Otowahr TrueSound©️ MEMS speaker utilizes a flat diaphragm within a uniform magnetic field, which the company claims results in more linear movement and lower distortion compared to the traditional moving coil drivers commonly found in earbuds. The company is able to achieve a refined acoustic performance without a significant increase in power consumption, thereby aiming to preserve battery life in the final product.
