Abstract

PURPOSE:To output only a sound output by effectively eliminating noise component of wind from a low speed to a high speed by providing a sensor for wind velocity detection near a diaphragm and by outputting a mixture of a signal from the sensor and that from a microphone. CONSTITUTION:Sensor 2 for wind velocity detection is arranged right in front of the vibration part of microphone 1 and a signal from microphone 1 and that from sensor 2 are mixed by mixing circuit 3. This mixing circuit 3 is provided with preamplifier 4 amplifying the signal from microphone 1 and preamplifier 6 amplifying the signal from sensor 2 and output signals of both those amplifiers 4 and 6 are mixed by differential amplifier 5, so that a sound signal can be outputted. Then when a noise due to wind pressure is inputted to microphone 1 simultaneously with the sound signal, sensor 2 detects a vibration component in the air and the noise component due to the vibration component is canceled by differential amplifier 5, so that only the sound signal can appear at its output.
