Abstract
A capacitor transducer, for instance a condenser microphone, is so designed that the stationary electrode can be mounted relatively quickly and in a relatively simple manner in the microphone housing. The transducer is provided with an inner cylindrical supporting wall spaced from the inner surface of the transducer housing. One end of the supporting wall is fixedly connected to the transducer housing through a transverse wall while the other end is remote from the transverse wall and constitutes a seat for the insulating body. The supporting wall in the insulating body are so dimensioned that the body can be mounted into its seat either by a pressing action or by insertion and subsequent retention by means of frictional forces or by means of an adhesive.
