ABSTRACT:
A compact electro-acoustic transducer assembly is provided having a housing formed with an acoustic output socket extending longitudinally of the housing and at least one electro-acoustic transducer mounted on the housing in registration with the acoustic output socket. The housing is provided with an aperture for transmission of sound waves from the acoustic output of the transducer to the socket. Conductive leads are deposited on the surface of the housing for providing electrical connection between the transducer and a circuit board supporting the housing. The electrical input terminals to the transducer are surface mounted thereon for engagement against the conductive leads deposited on the housing. The transducer may be formed with a thin plate-like permanent magnet formed of a rare earth cobalt material and supported in a flux-retaining member.
