Abstract
PURPOSE:To ensure an effective hearing aid through actuation of the counter device within the control unit after reception of the low-frequency pulse from the divider to deliver the necessary signals for the sound volume adjustment and others and then converting the voice once into the electric wave signal to be received through the hearing receiver device. CONSTITUTION:The voice is carried to the high-frequency signal sent from oscillator 55 using the crystal via mixer 56 and then transmitted in the form of the electric wave through amplifier 57 and transmitter device 58. The electric wave is received at receiver device 66 and then converted into the aural signal to drive amplifier 68, earphone 69 or converter 56 for artificial middle ear viat the control unit. With reception of the low-frequency pulse from divider 59, the counter device within control unit 67 is actuated by the pulse number to deliver the necessary signals. Thus, the sound volume control is given or microphone 65 is connected to amplifier 68, and at the same time the receiving device is cut off from the amplifier. In this way, the voice is converted once into the electric wave signal and then received at the hearing-aid receiver device to carry out an effective hearing aid.
