MINIATURE STYLISH NOISE AND WIND CANCELING MICROPHONE HOUSING, PROVIDING ENCHANCED SPEECH RECOGNITION PERFORMANCE FOR WIRLESS HEADSETS
A miniature microphone enclosure is provided for use with a wireless headset. The microphone enclosure provides superior noise and wind cancellation without any circuitry. Two sound ports and wind suppression material help minimize any noise attributable to wind or air. Moreover the microphone enclosure has a directivity such that the microphone does not have to be placed directly in front of a user's mouth.
1 . A microphone capsule comprising:
a first sound hole positioned at one end of the capsule facing a first direction;
a second sound hole facing a second direction different than the first direction;
a microphone aligned in a direction parallel to the direction the first sound hole faces; and
wind cavity buffer zones located in front and back of the microphone;
2 . The microphone capsule of claim 1 , wherein the wind cavity buffer zones contain foam to reduce wind turbulence near the microphone.
3 . The microphone capsule of claim 1 , wherein the angle between the first direction and the second direction determine the microphone sensitivity.
4 . The microphone of claim 1 , wherein the angle between the first direction and second direction is between 45° and 180°.
5 . The microphone of claim of claim 4 , wherein the angle between the first direction and second direction is about 90°.
6 . The microphone capsule of claim 1 , wherein the second sound hole is pear shaped.
7 . The microphone capsule of claim 1 , wherein the second hole is filled or covered with wind suppression material.
8 . The microphone capsule of claim 1 , wherein the outer housing is made of plastic.
9 . The microphone capsule of claim 1 , wherein the capsule has a cylindrical-like shape.
