A thin film piezo layer becomes the actuator, which bends when voltage is applied, and silicon –95% stiffer than paper or plastic – serves as the speaker diaphragm. As the piezo material bends, it ...

The resultant magnetic field interacts with the magnetic field of a strategically-located permanent magnet, and the diaphragm vibrates, thereby moving air and creating sound. This new paper-thin ...

Speakers used to be largish electromechanical ... so he 3D-printed a ring to support the PCB like a diaphragm over a small neodymium magnet. The sound quality was decent, but the volume was ...

The resulting technology, a speaker diaphragm, is designed for enhanced clarity, efficiency, precision and highest sound performance in order to make high audio quality accessible to the mass market.

Most speakers have round dome tweeters and cone midrange and/or woofer drivers, but the MMGi's thin-film, approximately 11 by 40 inch "quasi-ribbon" diaphragm produces bass, midrange and treble ...

A planar speaker, according to the post, uses wires and magnets to manipulate a flat film that acts as the transducer. The speaker housing is 3D printed and looks great but is otherwise unremarkable.

durable magnesium-coated speaker diaphragm. The result is full range of motion, low distortion and minimal vibration. The 225 PMD Series is composed of the NS-225F 2-Way Bass Reflex Tower Speaker ...

Last year, California's xMEMS Labs took aim at legacy coil-based speaker technology and decided ... xMEMS technology we saw last year, where thin-film piezo actuators excite a silicon membrane ...
