Abstract
A microphone boot system for reducing acoustic echo effect has a first compression structure; a first member of a microphone boot pressing against the first compression structure; second member of the microphone boot pressing against the first member of the microphone boot at an interface; a microphone interposed within a cavity formed by the first member of the microphone boot and the second member of the microphone boot; and a second compression structure juxtaposed against the second member of the microphone boot, such that the first compression structure and the second compression structure acting in concert form an acoustic seal at the interface. A method of reducing acoustic echo effect involves forming a first member of a microphone boot; forming a second member of a microphone boot; interposing a microphone between the first member of the microphone boot and the second member of the microphone boot; and applying a compressive force to the first member of the microphone boot and the second member of the microphone boot so as to form an acoustic seal between the first member of the microphone boot and the second member of the microphone boot at an interface thereinbetween.
