Loudspeaker manufacturing method
3. Detailed Description of the Invention The present invention is a method of melting the abovementioned nose gear holding the support cones and dampers themselves without using a speaker
cone, a damper or the like fixed to the housing of the speaker and an adhesive, The purpose is to
fix by welding, and thereby to prevent the occurrence of the generation of the bellow of the
speaker, to obtain a stable sound quality, and a speaker with good workability. As a method of
assembling a conventional speaker of this type, for example, a speaker cone, as shown in FIG. 1, a
rubber adhesive (hereinafter referred to as a bond) 2 is applied to the housing 1 of the speaker,
The cone ring 4 is coated with a bond 2 'on the periphery of the above-mentioned speaker cone
as shown in FIG. It was done by putting and holding the cone ring 4 on top. However, in the case
of such a method, if the amount of application of the bond 2 is small, the adhesion is partially
incomplete, causing a part of the bond to occur, and conversely, if the amount of application of
the bond is too large, FIG. As shown in FIG. 2B, the bond 2 'is pushed out, and after the speaker is
completed, the speaker cone 3 and the dried bond 292' collide with each other to cause the same
as the occurrence of the burr. Furthermore, when using this method, it takes at least 2 hours for
the bond 291 to dry, and 24 hours or more for the speaker to stabilize as EndPage: 1 for at least
2 hours to produce sound as a speaker. Therefore, a large amount of adhesive drying equipment
is required. Furthermore, since this pound contains about 70% organic solvent, a forced
ventilation system is needed to prevent the organic solvent from deteriorating the working

environment. In addition, there is a defect that the bond spreads to the corrugation i5 (edge) of
the speaker cone 3 at the time of assembly, which causes the occurrence of poor variation in
sound quality. Although the above description relates to the assembly of the speaker cone, the
assembly of the damper 6 and the housing 1 shown in FIG. 1 has substantially the same
drawbacks. The present invention eliminates these drawbacks. In the following, the embodiment
of FIG. 5 and FIG. 4 will be described. -Fig. 6 shows the assembly process of the speaker cone of
the speaker, wherein the housing 1 and the cone ring 4 or the pressing piece are themselves
formed of a heat fusible resin or made of other materials. The surface of the product is precoated with a heat-meltable resin.
The peripheral edge of the speaker cone 3 is placed on the housing 1 and the cone ring 4 is
placed thereon, and ultrasonic vibration is applied to these from the ultrasonic electrode 7 and
the housing 1, the speaker cone 3 and the cone described above As shown in FIG. 4, the
peripheral portion of the speaker assembled as described above is formed as a housing for the
speaker, by performing heat bonding to melt only the front surface of each contact portion of the
ring 4. 1. The speaker cone 6 and the cone ring 4 are integrated, so that this part does not cause
the speaker to be billed 9 and the ultrasonic assembly can be performed within a few seconds
There is no need to use conventional adhesive-agent drying equipment, and no adhesive
containing organic solvent is used, so there is no concern about the deterioration of the working
environment, and no forced ventilation system is available. To become. Furthermore, since the
adhesive does not infiltrate into a portion of the cone paper of the speaker cone as in the prior
art, a stable speaker with a stable sound quality can be obtained. -In the embodiment shown in
the figure, although the description has been made of the case where the speaker cone sheet is
erected, it goes without saying that the method of the present invention can be similarly applied
to the assembly of the damper 6 and the housing and the like. In the present invention, as
described in detail above, the speaker cone or the damper is held by the pressure-melting resin i
body + the housing coated with the formation or heat-melting resin and the pressing piece
(coating), and the holding portion The heat-melting resin of the speaker housing and the pressing
piece is heat-melted and fused together, so that it can be assembled without using any adhesive
as in the prior art, thereby the above-mentioned conventional- The defects caused by the law can
be eliminated, and the present invention's method prevents the generation of insults and insults,
stable sound quality and good business performance. Z2g4 force of the production side, there is
an advantage that can provide law.
