Speaker assembly method
3. Detailed description of the invention In the present invention, the speaker frame is coated in
advance with an adhesive such as a heat melting resin or a heat adhesive resin, and the speaker
frame such as cone paper or damper is coated on the coated speaker frame. The present
invention relates to a method of assembling a loudspeaker in which the attachment is assembled
by ultrasonic heating or high frequency heating and the like, and the purpose is to attach the
cone paper, the damper, etc. to the speaker frame. Each time the adhesive is applied without
being applied to the adhesive part, the adhesive can be adhered as it is, and the adhesive coating
of the adhesive part uniformly adheres to the speaker. The aim is to eliminate the occurrence, to
further increase the efficiency of this kind of assembly of the speaker, and to omit the production
equipment etc. Ru. In the conventional speaker assembly process, for example, when the speaker
housing and cone paper are assembled by adhesion, as shown in FIG. 1, a rubber adhesive
(hereinafter referred to as a bond) 2 is applied to the housing 1. It is done by placing and holding
corn paper 6 on top of it. However, when the amount of application of the above-mentioned bond
2 is small, the bond 2 is partially dried by the adhesive assembly of the corn paper 6 and the
adhesion failure between the corn paper 3 and the housing 1-from the speaker In addition, if the
amount of Bond 2 applied is too large, as shown in Fig. 2, no, EndPage: 1 (size out, after
completion of the speaker, cone paper, 6 and this hardened outflow bond 2 clash, which is what
causes the generation of the / / ビ 作 作 硬化 硬化 硬化 硬化 硬化 硬化 硬化 硬化 硬化 硬化 硬化
硬化 硬化 ま で ま で ま で ま で ま で ま で ま でIt takes at least 2 hours, and it takes 24 hours
or more to be stable as a speaker, which requires a large amount of adhesive drying equipment.
Furthermore, this bond contains 70 organic solvents, which do not deteriorate the working
environment due to the evaporation of the organic solvent, and thus requires a forced ventilation
system. The same is applied to the assembly with the damper 4 shown in FIG. 3 · 1 and there is
the same drawback as the above case. The present invention eliminates all the above-mentioned
conventional drawbacks and achieves the object mentioned at the beginning, and the example
shown in the drawings described below by the embodiment shown in FIG. 5 and FIG. in the case
where a cone paper 3) Ujingu adhere to 1 assembled on 2, / & Ujifugu to the first surface, whole
or locally the adhesive coating 5 such as heat-adhesive resin is a pre-heat-adhesive resin
dimension When the corn paper 6 is to be adhered to the paper sheet 1, the corn paper 3 is
placed on the adhesive film 5 of the paper sheet 1 as it is, and from there, it is shown in FIG. As
shown, by bringing the ultrasonic heating electrode 6 into close contact and applying ultrasonic
waves, the adhesive coating 5 is melted and the both are adhered.
In another method, the temperature of the housing 1 is raised by high frequency heating, and
when the adhesive coating 5 is melted, the corn paper 5 may be placed on the paper and pressed.
The peripheral portion of the cone 60 of the speaker assembled according to the method of the
present invention is uniformly bonded as shown in FIG. 4 and can completely prevent the
occurrence of the speaker's burring at this portion. In addition, ultrasonic welding and highfrequency welding can be performed in a few seconds, eliminating the need for conventional
large-scale adhesive drying equipment, thus eliminating the production equipment and
shortening the working time, and assembly efficiency Increase Furthermore, since the speaker
according to the present invention is coated with the adhesive film on the housing surface as
described above, there is an advantage that the film has an anti-corrosion effect except for the
bonding portion. The method according to the present invention can be performed by the same
method in bonding and assembling the damper 4 and the housing 1 to achieve the same purpose.
As described above, according to the present invention, the entire surface of the speaker frame or
the heat-melt adhesive or the heat-adhesive is coated locally, and another speaker component is
brought into contact with the coated portion. By adhering the above-mentioned speaker parts to
the entire speaker frame by ultrasonic wave [1 heat or high frequency heating, etc., the
conventional defects are eliminated, and the intended object of the present invention is achieved.
