Abstract
The present invention relates to a molded housing having an integral acoustic chamber and a plurality of post members which engage the printed circuit board contained therein to preclude rattling. As sound waves are generated within the acoustic chamber the sound waves travel along a directed path thereby enhancing the audible level of the sound waves allowed to escape the housing.
