Abstract
The invention relates to a multilayer composite vibrating diaphragm loudspeaker. The multilayer composite vibrating diaphragm loudspeaker comprises a frame, a magnetic loop, a voice coil and a vibrating diaphragm, wherein the magnetic loop is arranged on the frame, the voice coil is arranged in a magnetic gap of the magnetic loop, and the vibrating diaphragm is fixed to the frame and the voice coil and provided with a round outer edge. The multilayer composite vibrating diaphragm loudspeaker is characterized in that a tone tuning layer formed by combining a plurality of tone tuning units is arranged on the surface of the vibrating diaphragm, the tone tuning units are of a bar shape or a dot shape and are in zero-clearance fit with the vibrating diaphragm, and the tone tuning units are evenly distributed on the surface of the vibrating diaphragm in a spaced mode and are wholly rotationally symmetrical about the center of the vibrating diaphragm; the area of the tone tuning layer accounts for 0.1 to 0.7 of the total area of the surface of the vibrating diaphragm, and the mass ratio of the tone tuning layer to a vibrating diaphragm body of which the area is the same as that of the tone tuning layer ranges from 0.1 to 10. The multilayer composite vibrating diaphragm loudspeaker has the advantages that the mass distribution of the vibrating diaphragm is changed by arranging the tone tuning layer on the vibrating diaphragm, the voice characteristic of the loudspeaker is then controlled, the low-frequency response, the high-frequency response and the transient state are more balanced, and therefore the good voice effect is achieved.
