Abstract:
A receptacle assembly adapted to be fitted onto an acoustic transducer within a housing for acoustically sealing and guiding sound from the transducer, comprising:a receptacle device, formed of flexible material, having a first surface adapted to mate with a first side wall of the transducer, a second surface substantially parallel to said first surface and adapted to mate with a second side wall of the transducer, a third surface adapted to mate with a third side wall of the transducer, a fourth surface adapted to mate with a third side wall of the transducer, said third and fourth surfaces being substantially parallel to each other and perpendicular to said first surface and said second surface, a fifth surface substantially perpendicular to said first, second, third and fourth surfaces and adapted to mate with a top surface of the transducer, said surfaces forming a depression on said device that is adapted for mating with and sealing the acoustic transducer, such that said fifth surface presses the top surface of the transducer and said first, second, third and fourth surfaces mate with side walls of the transducer, wherein each of said surfaces has an area smaller than an area of the respective mating surface on the transducer; and said receptacle device having an acoustic waveguide on said surfaces forming a resonant cavity, the resonant cavity abutting an opening of the acoustic transducer on one end and an audio port opening of the housing on the other end, such that the acoustic waveguide diverts sound from the acoustic transducer.
