Abstract
A wedge-shaped receptacle for mounting a noise cancelling microphone transducer (105) and a ringer alert transducer (107) within a housing (101) is disclosed. The receptacle (111) is molded from a flexible material providing efficient assembly of the transducers within two apertures in the receptacle (129 and 133). Gaskets (137 and 145), molded as part of the receptacle, provide an acoustic and weatherproof seal between the receptacle (111) and the housing (101) for each transducer. The two apertures (129 and 133), providing acoustic interface for the ringer alert transducer (107) and the microphone transducer (105), share the same opening (113) in the front face of the housing (101). The aperture (133) for the noise cancelling microphone (105) is also open to a second opening (115) in the bottom face of the housing (101) to cancel background noise. The receptacle includes channels (201 and 202) which allow back pressure release for the ringer alert transducer (107 ). The receptacle (111) also dresses the microphone wires (141) through another aperture (131) to prevent damage during the assembly of the receptacle (111) into the housing (101).
