[0006] However, the original cloth will shrink after desizing, resulting in the size of the desizing original cloth being smaller than the size of the original cloth containing the pulp, so that the total area of the speaker vibrating piece that can be produced by the desizing original cloth is smaller than originally expected, and it can Fewer horn diaphragms were manufactured than originally expected
[0007] In this regard, some people in the industry tried to use pulp-containing raw cloth to manufacture horn vibrating pieces, but found that compared with the horn vibrating pieces produced by desizing raw cloth, the raw pulp-containing cloth after impregnation, drying, and molding After steps such as cutting and cutting, the manufactured speaker vibrating piece is more likely to be deformed

The invention discloses a production method for loudspeaker vibration diaphragm through application of sized raw cloth. The method comprises the following steps of sizing a cloth raw material to obtain sized raw cloth; impregnating the sized raw cloth into resin solution; drying the sized raw cloth; forming loudspeaker vibration diaphragm preset shapes on the sized raw cloth; cutting the loudspeaker vibration diaphragm preset shapes from the sized raw cloth, thereby obtaining the loudspeaker vibration diaphragm which is liable to deform; and wetting the loudspeaker vibration diaphragm which isliable to deform and then carrying out dewatering, thereby obtaining the modified loudspeaker vibration diaphragm. According to the method, the number of the loudspeaker vibration diaphragm producedthrough application of the sized raw cloth is kept at the expected number and the loudspeaker vibration diaphragm is not liable to deform.
Description
technical field [0001] The invention relates to a manufacturing method of a horn vibrating piece, in particular to a manufacturing method of a horn vibrating piece using pulp-containing raw cloth. Background technique [0002] Please refer to figure 1 Generally, a typical dynamic speaker 1 includes a power system, a drum paper 2 and a suspension system. The power system further includes: magnet 6 , pole piece, upper iron, gap and voice coil 5 . The drum paper 2 is a diaphragm used to move air, generally a cone or hemispherical sound cone. The suspension system is composed of spring wave 3 and suspension edge 4, which are used to pull the directional movement of the diaphragm. Its working principle is that when the current flows through the voice coil 5, an electromagnetic field is generated, and this electromagnetic field is at right angles to the magnetic field of the permanent magnet 6 on the speaker, which makes the movable coil be stressed by the gap (the gap between ...
