ABSTRACT:
The electroacoustic transducer comprises an oscillating element (6, 7) holding a coil (8), the oscillating element (6, 7) being connected to a magnet frame (11-17) by an elastomer ring (10'). The magnet frame (11-17) has two magnets (14, 15) and constitutes an inertial mass. The oscillating element (6, 7) is intended to be attached rigidly by its base plate (6) to a panel (1) so that the sound waves are transmitted to the latter (1) which thus plays the role of a speaker diaphragm. Adjusting screws (27) make it possible to modify the characteristics of the elastomer (10') as a function of the mounting condition and the desired sound diffusion effect.
