Abstract
The utility model discloses a tapered cone without a central hole, which comprises bending rings and a diaphragm. The central part of the diaphragm protrudes upwards so as to form a connecting chamber on the diaphragm center lower surface. The utility model also discloses a loudspeaker using the tapered cone. The diaphragm center is provided with no through hole. A similarly blind hole structure is then formed. After the diaphragm is connected with a voice coil, the projection on the diaphragm center, namely the bump can right protect the voice coil. Dust is completely prevented from entering a magnetic gap. The use and installation of a dust shield can be no longer required. The element cost and the assembly cost are lowered. Meanwhile, bonding parts are reduced. Product qualities are enhanced. Meanwhile, the loudspeaker without the dust shield adopts an integral cone structure. The loudspeaker makes use of the cone transmission and meanwhile does not damage the integrity of the diaphragm. Product instability caused by excessive connection parts is prevented. Product quality stability is thus effectively increased.
