Zusammenfassung:The present invention relates to an apparatus which includes a speaker and a microphone, such as a telephone, intercom, two-way radio and the like, and more particularly, to an apparatus which includes a speaker and a microphone which provides acoustical and mechanical isolation between the speaker and a microphone to provide improved audio performance as well as allow for streamlined manufacturing of the apparatus and thus reduced costs. An apparatus for a microphone and speaker is provided which provides a sealed chamber behind the speaker to prevent sound waves behind the speaker from cancelling sound waves in front of the speaker. In addition, the apparatus is configured to mechanically isolate the speaker from the apparatus housing in order to improve performance of the system. A pliant material such as a damping material with a relatively linear compression characteristic, such as a thermal plastic elastomer, may be used to isolate the speaker from the apparatus housing as well as providing a relatively air tight chamber behind the speaker.
