ABSTRACT OF THE DISCLOSURE Multiple loudspeaker with piezoelectric "tweeter" supported in such a way as to allow complete exploitation of the main loudspeaker diaphragm the surfaces of which reflects the ra- diation emitted from the rear by the ceramic disk and by the piezoelectric tweeter diaphragm. This invention concerns a multiple loudspeaker with a piezo electric tweeter held up by a means of support which allows the rear wave emitted by the ceramic disk and re- spective conical diaphragm to be fully exploited, using the main loudspeaker cone as a reflecting surface without overloading the moving coil of the latter. The invention is basically characterized by the fact that the piezoelectric tweeter is placed in front of the main loudspeaker cone without the traditional protection and support basket but using a different means of support which does not intercept or disturb the rear radiation from the piezoelectric "tweeter", or prevent the forward reflection of the radiation by the main loudspeaker dia- phragm.
