Abstract
A microphone enclosure for reducing the intensity of sound waves that reach a microphone is presented. The enclosure may be a solid mass with a cavity, designed so that most of the microphone is surrounded by the solid mass when the microphone is inserted into the cavity. The solid mass is dense enough to reduce much of the sound waves that are first mechanically and then acoustically coupled with the microphone. The microphone may be inserted into the cavity so that a sound receiving section is exposed at the entrance of the cavity. Also, the microphone may not be inserted to the end of the cavity so that there is a space between the end of the cavity and the microphone. A hole may be located on the cavity sidewall so that sound can reach the microphone through this space. The sound receiving sections of the microphone are aligned with openings in the communications device.
