ABSTRACT:
An assembly housing for accepting an electroacoustical transducer having a rear face with terminal pins proceeding therefrom, contact surfaces thereon, and at least one sound admission opening, is formed by an acceptor plate which is disposed adjacent the rear face of the electroacoustical transducer, and a covering cap which is fitted over the radial edge of the acceptor plate. The acceptor plate has respective openings therein proceeding completely through the acceptor plate which respectively receive the terminal pins, and has blind holes therein which respectively receive springs in registration with the electrical contact surfaces of the electroacoustical transducer. The acceptor plate has a radially-proceeding sound admission channel therein, with one end in registration with the sound admission opening in the rear face of the transducer, and an opposite end in registration with a sound admission opening in the covering cap.
