  • Patent number: 9179234
    Abstract: There is provided a process for assembly of a capacitor microphone. The capacitor microphone has a frame and a counterpart electrode. The counterpart electrode is positioned in the frame and held. Adhesive is applied so that the counterpart electrode is glued directly to the frame.
    Type: Grant

  • Patent number: 8019101
    Abstract: The present invention is directed to a condenser microphone with a microphone housing cap with a sound inlet opening, a microphone housing with a cross-sectional opening facing the microphone housing cap, and a diaphragm resting along the cross-sectional opening on the front side of the microphone housing surrounding the cross-sectional opening, and a counter-electrode which faces this diaphragm and which is arranged at a short distance from the diaphragm. The invention is further directed to a corresponding method for producing a condenser microphone of this kind. The invention provides an improved condenser microphone and an improved method for producing such a condenser microphone so that the disadvantages of the prior art are overcome while reducing manufacturing-related resources and, therefore, costs at the same time in that the diaphragm of the condenser microphone is glued to the microphone housing in an angle area between the underside of the diaphragm and the outer side of the microphone housing.

  • Patent number: 7881484
    Abstract: The present invention concerns a capacitor microphone comprising a microphone housing having a sound inlet opening, a diaphragm and a counterpart electrode which is associated with the diaphragm and which is arranged at a small spacing relative to the diaphragm. In order to be able to construct such a capacitor microphone with the smallest possible dimensions with at the same time a high signal-noise ratio and without worsening the electro-acoustic parameters, it is proposed in accordance with the invention that the microphone housing has two housing portions of which the second housing portion is of a larger diameter than the first housing portion and the second housing portion is arranged in the form of a cap or sleeve over the first housing portion and the edge of the diaphragm is folded over the edge of the first housing portion and fixed to the outside of the first housing portion.
