Electroacoustic signal transmitter

摘要

A ringing second apparatus is illustrated and described for telephone installations, having an apparatus housing (10), an apparatus insert (13) accommodated therein and a sound transducer element (12) which is accommodated by a transducer housing (11) which is connected to the apparatus housing (10) by means of sprung arms (19), such that it is acoustically decoupled. In order in this case to make it possible for the apparatus to be able to accommodate additional components, such as a telecommunications line unit (TLU) for example, without having to use a housing which is larger than that for the prior art, it is provided according to the invention that the transducer element (12) is accommodated in the interior of the apparatus housing (10) close to an apparatus wall (27, 27a) that the transducer housing (11) is constructed essentially as a flat retaining frame (17) for the transducer element (12), that the apparatus wall (27) has a recess (29) which at least partially accommodates the transducer housing (11) and the apparatus insert (13) is held via stops (26) at a distance from the apparatus wall (27a) such that a free oscillation space is formed there for the transducer element (12). <IMAGE>
