Description
Technical Field
The present invention relates to a method for manufacturing a vibrating reed of a loudspeaker, and more particularly, to a method for manufacturing a vibrating reed of a loudspeaker using a cloth containing a paste.
Background
Referring to fig. 1, a typical moving coil speaker 1 includes a power system, a drum paper 2 and a suspension system. The power system further comprises: magnet 6, pole piece, upper iron, gap and voice coil 5. The drum paper 2 is a diaphragm for moving air, and is generally a cone or a hemispherical cone. The suspension system is composed of structures such as an elastic wave 3 and a suspension edge 4 and is used for dragging the vibrating diaphragm to move directionally. The working principle is that when current flows through the voice coil 5, an electromagnetic field is generated, which is directed at right angles to the magnetic field of the permanent magnet 6 on the horn, which forces the moving coil to move in the gap (the gap between the voice coil 5 and the magnet 6). The mechanical force generated by this movement causes the drum paper 2 attached to the voice coil 5 to generate vertical, up-and-down movement (vibration), so that the air is vibrated to emit audio to the human ear, thereby achieving the purpose of sound restoration for human listening and realizing the conversion of electric energy into sound energy.
The non-metal parts included in the speaker 1 are made of raw cloth, and the main reason is that the raw cloth after special treatment has proper elasticity and strength to provide the required function of the speaker, such as the drum paper 2 and the elastic wave 3, and the non-metal parts are collectively called as the speaker vibrating plate. The existing loudspeaker vibrating piece manufacturing method is to use desized original cloth and form a finished loudspeaker vibrating piece product through the steps of resin impregnation, drying, forming, cutting and the like.
Further, in order to reduce friction generated during weaving, prevent breakage of warp yarns, improve the efficiency of the raw fabric, the quality of the raw fabric, and the like, it is necessary to perform a warp sizing and warping process in advance when the raw fabric is woven by using the warp yarns and the weft yarns, thereby increasing the conformability and smoothness of the warp yarns. Therefore, the prepared original cloth contains the pulp and is called pulp-containing original cloth.
However, if the raw cloth contains pulp, the permeability of the raw cloth with a refining agent at the time of refining, a bleaching agent at the time of bleaching, a dye at the time of dyeing, and the like, and further the completeness of the raw cloth refining are affected, and the uniformity of whiteness of the bleached fabric and the permeability of the dye to the raw cloth at the time of bleaching, and further the dyeing effect of the raw cloth are affected, so the raw cloth containing pulp is generally subjected to a desizing treatment to remove the pulp from the raw cloth containing pulp to obtain a desized raw cloth, and the desized raw cloth is subjected to processing treatments such as refining, bleaching, dyeing, and the like.
However, the desized cloth has a smaller size than the size of the cloth containing the desized cloth, so that the total area of the desized cloth for manufacturing the loudspeaker vibrating pieces is smaller than the area expected before, and the number of the loudspeaker vibrating pieces can be smaller than the number expected before.
In contrast, the inventors tried to manufacture the horn vibration piece using the paste-containing raw cloth, but found that the manufactured horn vibration piece is more easily deformed after the steps of impregnation, drying, molding, cutting, and the like, compared with the horn vibration piece manufactured by desizing the raw cloth.

In the second sizing method, the cloth material is a raw cloth 13 interwoven by a plurality of warp yarns 11 and a plurality of weft yarns 12, and the raw cloth 13 is soaked in the size 14 to obtain a size-containing raw cloth 20, as shown in fig. 2 (B). Wherein the slurry 14 is starch, dextrin of starch conversion products, soluble starch, sodium alginate, bovine gelatin, carboxymethylcellulose, sodium cellulose zincate, polyvinyl alcohol, polyacrylic acid, or a combination thereof.

Cutting: the predetermined shape of the horn vibration plate is cut out from the slurry containing cloth 20 to obtain an easily deformable horn vibration plate 60. More specifically, the slurry containing cloth 20 is moved to a cutting device 70, and the horn vibration piece predetermined shape is cut from the slurry containing cloth 20 by the cutting device 70 to obtain the horn vibration piece 60 which is easily deformed.
Modification: the horn vibrating reed 60 which is easy to deform is wetted and then dehydrated to obtain a modified horn vibrating reed 61. Thus, the modified horn diaphragm 61 is improved in deformation resistance and less likely to deform, and is therefore suitable for use in a horn.
