A new range of piezoceramic speakers features a flat construction that allows them to be used in applications where in the past space was a problem

The SPS series is based on a sandwich construction of a specially shaped piezo disk and a composite polymer membrane. The complex polymer membrane reduces resonance peaks and converts energy into a damped frequency response curve with low distortion. High sound quality and low distortion guarantee good reproduction of both music and speech.

Applications for the product include door entry systems, onboard public address systems in trains and buses, vending machines and nurse call systems.
