A capacitive transducer, in particular a condenser microphone, with a ring-shaped member and a diaphragm secured to the ring-shaped member. A disc-shaped member is secured in the opening of the ring-shaped member and in parallel relationship to the diaphragm. The disc-shaped member has an electrically conductive portion spaced from the ring-shaped member and facing the diaphragm in a predetermined distance therefrom, whereby the diaphragm and the electrically conductive portion on the disc-shaped member form an electrical capacitor. The second side of the disc-shaped member and the contact member are directly accessible. Also, the ring-shaped member has, outside the outer periphery of the diaphragm, a free surface extending transversally to the axis of the ring-shaped member for mounting in a microphone housing with the diaphragm flush with the front end of the microphone or slightly recessed relative to the front end.
