Polymer-metal piezoceramic speakers have numerous applications

4 April 2007 Analogue, Mixed Signal, LSI

Based on its expertise in vibration characteristics of piezoceramic material and micro-acoustics, Sonitron successfully developed the SPS-series of piezoceramic speakers for industrial, multimedia and automotive applications.

The SPS series (Sonitron polymer-metal speakers) is based on a new principle of piezoceramics and a composite polymer-metal membrane. This composite membrane reduces unwanted resonance peaks to provide a more even frequency response than can be achieved with conventional designs. Its high sound quality and low distortion ensure that the reproduction of music and speech is of a very high quality.

Piezoceramic speakers offer a faster response than conventional magnet speakers because of their lower mass (no voice coil). Magnet speakers are also less efficient because of losses in the coil. Piezoceramic speakers have a low weight and low energy consumption relative to their sound output levels. Further, they do not produce an electromagnetic field, making it easier for designers to ensure their products meet EMC requirements.

Sonitron's SPS speakers have a very flat design and are delivered with an open front. They can be used in difficult environments because of the resistance of the facing area to water, humidity, vibration and dust. Typical applications are for mobile phones, PDAs, LCD monitors, car audio, instrumentation PA systems etc.
