Method of custom designing directional responses for a microphone of a portable computer

A portable computer having a microphone for receiving acoustic signals and generating a directional response associated with a desired polar pattern, comprising:

• a processor for activating said microphone and processing electrical signals corresponding to acoustic signals received by said microphone;
• a container, comprising:
• a bottom shell housing said processor;
• and
• a top shell having a front-surface and a rear surface, connected to said bottom shell;
• a microphone located between said front and rear top shell surfaces, said microphone comprising:
• a microphone element for receiving acoustic signals;
• and
• a boot for mounting and isolating said microphone element, said boot configured to achieve a desired microphone directional response associated with a particular polar pattern to compensate for noise sources internal to the portable computer,
• wherein the position of said microphone element defines a front distance and a rear distance, the front distance being the distance between said microphone element and said front shell surface, and the rear distance being the distance between said microphone element and said rear shell surface, and
• wherein said front distance and said rear distance are varied to achieve a desired microphone directional response associated with a particular polar pattern.

• wherein said boot is configured to adjust a particular polar pattern to achieve a form-fitted directional microphone response,
• wherein the position of said microphone element defines a front distance and a rear distance, the front distance being the distance between said microphone element and said front shell surface, the rear distance being the distance between said microphone element and said rear shell surface, and
• wherein said adjustment is achieved by varying the front distance and said rear distance to set the null regions of said particular polar pattern.
