Abstract

The electroacoustic transducer according to the invention has at least one diaphragm and at least one counterelectrode. In that case the diaphragm and/or the counterelectrode each have at least two electrically mutually insulated segments. In that arrangement the segments are so adapted that different electric signals are supplied or that different electric signals are delivered in response to exposure to sound of the sound transducer.
