  • Hearing aid
    Patent number: 4440982
    Abstract: A hearing aid includes a duct (10) for transmitting the sound from the receiver (2) to the exterior of the housing (1) of the hearing aid. The duct is formed in a component (9) which is constituted by a body of an elastic damping material and which also serves as the sole suspension means for the receiver (2). The suspension means supports the receiver mainly on that side of the receiver where the sound outlet (12) of the receiver is located. This minimizes the mechanical-acoustic coupling between the receiver and the microphone (3) of the hearing aid.
