The micro speaker for wireless earbuds delivers clear sound without an amplifier, uses less power, lowers cost, and fits ...

The new micro-speaker, which is smaller and more accurate ... Lassen does not require a separate piezo amplifier chip—it takes up less space than other solid-state audio solutions.

Called xMEMS Lassen, this new micro-speaker delivers up to 115dB SPL in the 6kHz to 20kHz ... The previous xMEMS Cowell and Muir MEMS speaker solutions for 2-way earbuds required a separate piezo ...

This puts solid-state MEMS speaker technology on par with other micro tweeter solutions, including balanced armature and planar magnetic drivers. Amplifier-free design: Lassen eliminates the need for ...

This simple STM setup utilises a piezoelectric actuator constructed by deliberately cutting a piezo speaker into four quadrants ... The reason for the high-speed micro is the need to control ...
