    摘要: An acoustic damper for covering a housing inlet of a transducer is disclosed. The damper includes a mesh panel and a non-mesh periphery. The non-mesh periphery of the damper is adhesively attached to the housing of the transducer wherein the mesh panel covers the inlet. The non-mesh periphery of the damper inhibits the adhesive from wicking into the mesh panel. The damper is adaptable for attachment of a film. The film is capable of cooperating with a backplate to form a motor assembly of the transducer.

    摘要: An electret condenser microphone includes a housing (101), a diaphragm (108a) disposed within the housing (101), first and second sound inlet ports and an acoustic resistive material (118) disposed within the housing and in the acoustic path between the second inlet port and the diaphragm (108a). The acoustic resistive may further electrically couple a backplate (112) coupled to the diaphragm (108a) to an amplifier disposed within the housing (101).

    摘要: A receiver assembly for a hearing aid device, the assembly comprising a case having an inner cavity, one or more mounts disposed within the inner cavity of the case, and a receiver disposed within the inner cavity of the case and connected to the mounts such that the receiver is suspended within the inner cavity of the case. The mounts dampen any vibration transmission from the receiver to the case and from the case to the receiver. Most significantly, acoustical noise from the receiver and any resulting distortion, feedback, and/or interference within the other components of the hearing aid device are substantially eliminated.

    摘要: A method and apparatus for substantially reducing and virtually eliminating direct current flow through the input transistor(s) of an input buffer circuit for an electret microphone is disclosed. An input transistor is provided and operably connected to an input and an output of the input buffer circuit. The input transistor has a first operating state wherein current flow occurs in a first direction and a second operating state wherein the a current flow occurs in a second direction ― opposite that of the first direction. The input transistor is biased to alternately control operation between the first operating state and the second operating state. The alternating, opposing flows of current of the respective operating states cooperate to substantially reduce and virtually eliminate the flow of direct current through the input transistor(s) of the buffer circuit. A reduction in excess noise associated with the input transistor results from the substantially decreased direct current flow through the input transistor(s) of the buffer circuit.

    摘要: An impedance matching, reducing, or buffering circuit for permitting smooth signal flow from a first transmission medium to a second transmission medium. The circuit provides a first node adapted for coupling to the first transmission medium and for receiving a signal from the first transmission medium. The circuit further provides a buried channel transistor, that is coupled to the first node and that is biased by additional circuit devices, for transforming the impedance imposed on the signal. The use of the buried mode transistor reduces noise on the surface of the transistor while at the same time keeps other performance standards high. The circuit additionally provides a second node that is coupled to the buried channel transistor and that is adapted for coupling to the second transmission medium for conveying the signal to the second transmission medium.
