SPS-SERIES
INTRODUCTION
Based on the in-house expertise in vibration characteristics of piezoceramic material and microacoustics,
Sonitron successfully developed the SPS-series piezoceramic speakers for industrial,
multimedia and automotive applications. The SPS-series is based on a completely new principle of
piezoceramics and a composite polymer/metal membrane. The composite polymer/metal
membrane reduces unwanted resonance peaks to provide a more even frequency response than
can be achieved with conventional designs. High sound quality and low distortion guarantee
perfect reproduction of music and speech.
Piezoceramic speakers offer a faster response than conventional magnet speakers because of their
lower mass (no voice coil). Magnet speakers are less efficient than piezo speakers because of the
losses via the voice coil. Piezoceramic speakers also 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.
Sonitron’s SPS speakers 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.
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.
