Piezoceramic Speakers & Amplifiers - SPS series


Sonitron Polymer/metal Speakers (SPS)  produce high sound quality with low distortion and guarantee perfect reproduction of music and speech.


They have a very flat design and are delivered with an open front. They can be used in difficult environmental conditions and applications because of resistance of the front to water, humidity, vibrations and dust.


Piezoceramic speakers feature a low weight and low energy consumption relative to their sound output levels. They do not generate an electromagnetic field, making it easier for designers to ensure that their products meet EMC requirements and regulations.

The described models are released for applications such as mobile phone, PDA, flat LCD computer screens and computer monitors, consumer products, car audio, instrumentation, portable devices, public address systems, paging systems, etc.
