  • Noise cancelling microphone
    Patent number: 5329593
    Abstract: A noise cancelling microphone for use in noisy environments is disclosed wherein noise entering the front portion of the microphone housing to impinge upon the microphone cartridge diaphragm is also permitted to enter proximate the rear portion of the microphone housing through strategically located inlet openings. This allows noise to impinge upon the back surface of the microphone cartridge diaphragm to effect a cancellation of diaphragm vibrations. These strategically located inlet openings at the top and the bottom of the rear of the microphone housing are situated so as to be directionally orientated towards the greatest source of the noise, namely orthagonal to the directional line of the front inlet openings and out of the path of the incoming air.
