Sonitron Polymer/metal Speakers (SPS) produce high sound quality with low distortion and guarantee the 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.
