Abstract
Custom designed polar patterns for a microphone of a portable computer are achieved. A custom designed polar pattern permits a microphone in a portable computer to suppress sources of spatially-dependent noise internal and external to a portable computer system. A custom designed polar pattern is generated by specially configuring the boot of a microphone by varying the hole sizes of the boot and/or varying location of the microphone element in the boot. In addition, the shape of a particular polar pattern may be adjusted by inserting acoustic absorption material into the boot, forming enclosed walls into the boot, or rotating the top shell of the portable computer which contains the microphone relative to the bottom shell of the portable computer. Thus, a directional response of a microphone may be form-fitted to a particular portable computer configuration.
