DETAILED DESCRIPTION OF THE INVENTION In the present invention, the above-mentioned
housing which holds 1 l II of the above-mentioned housing and its pressing piece itself are used
without using a layering agent, such as a speaker cone or f-tbar which is fixed to a speaker It is
intended to secure the speaker by fixing it by R-welding, and this aims to obtain a stable speaker
with stable sound quality as well as stable sound quality, as well as stable operation. Speakers of
the species, for example Subic Kako-gs-i3β '. As shown in FIG. 1, a rubber adhesive (hereinafter
referred to as a bore k) 3 is applied to a housing 1 of a speaker, and is covered, and the
peripheral edge of Subika Kako y3 is placed on top of that and pressed down. As shown in FIG. 8,
a mat y and a cone ring number are coated with poYVm 'on the periphery of the upper IH
speaker cone 3 and a cone ring number is placed thereon. It was done by holding down.
However, in the case of such a method, if the amount of application of the bond 3 is small, the
adhesion is partially incomplete and adhesion is generated at that portion, and conversely, if the
amount of application of the bone V is too large, the second Bond as shown in the figure. The
moth is pushed out, and after the speaker is completed, the speaker cone 8 and the dried bon VB,
2 'collide with each other, which causes the generation of the same as the above. Furthermore,
when using this method, it takes a drying time of Bond "3, 3", and it takes at least S hours before
it can produce sound as a speaker and 34 hours or more before it becomes stable as a speaker.
As 8 o's and so on which require extensive adhesive drying facilities, 8 lbs contain an organic
solvent near Te O, so this organic solvent does not force the aim of making the aim area foolish.
A paranoid device is a must. Also, at the time of writing, the pong r penetrates into the
corrugation Yoshi 11 (edge) of the speaker cone 8 and there is a defect that causes the sickness
to suffer from the life of the palus in the sound quality. Although the above description relates to
the assembly of the speaker cone, there is substantially the same drawback as to the assembly of
the damper 6 and the housing l, which has been lowered. The present invention eliminates these
drawbacks, and in the following, the embodiment shown in FIGS. 183 and 4 will be described
with reference to FIG. 8 which is a side sectional view of the speaker half showing the speaker
cone 8fm standing up. In this case, the housing 1 and the cone ring 4, that is, the pressing piece
itself is formed of a heat-melting resin itself or made of another material!
周 Use the heat-meltable resin pre-coated on INI. 0 Place the four edges of the speaker cone 8 on
this housing l and place a 5-3 / ring number on it, Bonding is carried out by heating and melting
only the surfaces of the contact portions of the housing l, the speaker co v8 and the cone ring 4
described above. As shown in the fourth factor, the side portion of the speaker assembled in this
manner is integrated with the speaker housing 11 speaker cone 魯 g and yyvy 、, thereby
allowing the speaker to be squeezed from this portion The conventional large-scale adhesive
drying equipment is not necessary, and no adhesive containing a solvent is used. So, there is no
concern for production * s + m foolishness, and the m control ventilation system is also
dissatisfied, so no adhesive bleeds into 0 minutes of the cone paper of the speaker cone as in the
prior art. A speaker with stable sound quality can be obtained. Note that, in the example of the
figure, the case of the speaker 2 of 7 sheets in 5 groups was described, but the assembly of the
damper 6 and the housing, etc. It is of course also possible to the aircraft. As described in detail
above, the uninvention, as described in detail above, holds the a-contact speaker cone or damper
by the housing 2 and the pressing ring (cone ring) which are formed of the heat-melting resin
itself or coated with the heat-melting resin beforehand. Since the heat melting resins of the
speaker nose 1 and the pressing piece of the sandwiching portion are attached to each other by
heating bath lk, they are assembled without using any adhesive as in the prior art. By this, it is
possible to eliminate the defects caused by the above-mentioned conventional method, and to
prevent the occurrence of the distortion of the speaker, and to provide a stable f quality and a
speaker with excellent operability.
