ABSTRACT:
A loudspeaker primarily for the high frequency audio region includes a driving device coupled to a diaphragm of convex outer configuration and extending over more than 180.degree. spherical angle. The driving device changes the distance between the two coupling areas of the diaphragm under the action of an electrical signal applied thereto. Elastic deformations appear on the diaphragm which give rise to an emission of soundwaves.
