Abstract
An electronic device includes an internal microphone that is located remotely from a microphone aperture formed in the enclosure of the electronic device. An acoustic chamber is formed within the electronic device to couple the microphone to the microphone aperture. The acoustic chamber is designed with a particular length to volume ratio that amplifies a particular range of frequencies such that the microphone maintains equal sensitivity to a desired frequency band.
