Abstract
Abstract A system for establishing a generally elongated and preferably also generally flat pattern of response for a microphone. A microphone pickup module according to the invention has a body with an elongated, preferably also generally flat, channel extending therethrough between generally oppositely facing open ends. A miniature pressure type microphone is mounted in the body with its sound-sensitive surface in communication with the channel intermediate the ends of the channel. The system provides improved response characteristics for the harmonica, accordion and drum.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A microphone pickup module having a generally elongated pattern of response, which comprises: a body having an elongated channel extending therethrough between generally oppositely facing open ends; and a microphone mounted in said body and having a sound-sensitive surface area in communication with said channel intermediate said ends of said channel; said elongated channel being generally flat, whereby said elongated pattern of response is also generally flat; said sound-sensitive surface area being substantially centered along the length of said channel; and said channel being substantially straight.
Claim 2
Dependent Claim
86 words
A microphone pickup module having a generally elongated pattern of response, which comprises: a body having an elongated channel extending therethrough between generally oppositely facing open ends; and a microphone mounted in said body and having a sound-sensitive surface area in communication with said channel intermediate said ends of said channel; said elongated channel being generally flat, whereby said elongated pattern of response is also generally flat; said sound-sensitive surface area being substantially centered along the length of said channel; and said channel being substantially straight.
Claim 3
Dependent Claim
20 words
A microphone pickup module as defined in claim 1, wherein said channel has a substantially uniform cross-section along its length.
Claim 4
Dependent Claim
36 words
A microphone pickup module as defined in claim 1, wherein said microphone is a miniature pressure-type microphone, and said sound-sensitive surface area is arranged substantially as a continuation of a generally flat surface in said channel.
Claim 5
Dependent Claim
96 words
A microphone pickup module having a generally elongated pattern of response, which comprises: a body having an elongated channel extending therethrough between generally oppositely facing open ends; and a microphone mounted in said body and having a sound-sensitive surface area in communication with said channel intermediate said ends of said channel; said elongated channel being generally flat, whereby said elongated pattern of response is also generally flat; said channel having a cross-section that is generally rectangular and substantially uniform along its length; and the width of said generally rectangular cross-section being substantially five times the depth.
Claim 6
Dependent Claim
96 words
A microphone pickup module having a generally elongated pattern of response, which comprises: a body having an elongated channel extending therethrough between generally oppositely facing open ends; and a microphone mounted in said body and having a sound-sensitive surface area in communication with said channel intermediate said ends of said channel; said elongated channel being generally flat, whereby said elongated pattern of response is also generally flat; said channel having a cross-section that is generally rectangular and substantially uniform along its length; and the width of said generally rectangular cross-section being substantially five times the depth.
Claim 7
Dependent Claim
94 words
A microphone pickup module having a generally elongated pattern of response, which comprises: a body having an elongated channel extending therethrough between generally oppositely facing open ends; and a microphone mounted in said body and having a sound-sensitive surface area in communication with said channel intermediate said ends of said channel; said elongated channel being generally flat, whereby said elongated pattern of response is also generally flat; said channel having a cross-section that is generally rectangular and substantially uniform along its length; and the length of said channel being substantially ten times the width.
Claim 8
Dependent Claim
94 words
A microphone pickup module having a generally elongated pattern of response, which comprises: a body having an elongated channel extending therethrough between generally oppositely facing open ends; and a microphone mounted in said body and having a sound-sensitive surface area in communication with said channel intermediate said ends of said channel; said elongated channel being generally flat, whereby said elongated pattern of response is also generally flat; said channel having a cross-section that is generally rectangular and substantially uniform along its length; and the length of said channel being substantially ten times the width.
Claim 9
Dependent Claim
109 words
