(57) 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
respective 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 diaphragm.
