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 ...

Most of those speakers use diaphragms to make sound that are made from plastic or some sort of fiber material. Panasonic has announced a new loudspeaker that has a diaphragm made in part from ...

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 ...

In the xMEMS design, the paper/plastic diaphragm found in a conventional speaker is replaced by a much stiffer silicon membrane while the coil and magnet is swapped for thin-film piezo actuators.

You’ve never seen speakers like these. Instead of a traditional speaker diaphragm, plasma arc speakers use a modified carbon arc lamp to produce sound. The best part? You can build them yourself ...

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.

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 ...
