Abstract

PURPOSE:To collect the clear sounds free from the noise without impairing the original characteristics, by providing the vibration detector within the case and then adding the detection signals so as to show the opposite phase to the noise signal sent from the unit. CONSTITUTION:Microphone assembly A consisting of magnet 4, yoke 5, diaphragm 7 with voice coil 6 and others is provided at front part 2 of microphone unit 2. And cancel coil 8 is turned round the basement part of assembly A to give offset to the disturbance vibration, and magnet 9 is fixed on the inner surface of case 1 and in opposition to coil 8 to form the vibration detector. Furthermore, coils 6 and 8 are connected so as to secure the opposite phase to each other against the disturbance vibration. As a result, only the external vibration causing noise component can be eliminated through offset without impairing the acoustic characteristics of the microphone.
