Abstract

PURPOSE:To make it possible to generate satisfactory acoustic output characteristics by preventing the unnecessary vibrations such as divided vibrations in a dome type diaphragm with the use of a brake. CONSTITUTION:A brake 11 made of an elastic materialf is attached to the upper side 3A of the pole 3 of a magnetic circuit such that is abuts against both the inner wall of a coil bobbine 7 wound with a voice coil 6 and arranged in the magnetic gap G of a magnetic pasage and the inner wall 5A in the vicinity of the fixing portion a to the coil bobbine 7 of a dome-shaped diaphragm 5. The brake 11 is made of a material such as rubber, foamed rubber or sponge so that the inner wall 7A of the coil bobbine 7 and the inner wall 5A of the diaphragm 5 are elastically supported. The diaphragm 5 has its vibrations braked such that the unnecessary vibrations such as noded vibations, diametrical deformation and eccentricity are eliminated.
