Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a speaker used in various types of audio equipment.The structure of a conventional example and its problems Generally, a speaker is structured as shown in FIG.

That is, a frame 6 is connected to a magnetic circuit 5 constructed by laminating a ring-shaped magnet 3 and a ring-shaped upper plate 4 on a play 1-2 having a center ball 1, and a gasket is attached to the periphery of this frame 6. A cone-shaped diaphragm 80 is connected to the diaphragm 7 by adhesive on its entire periphery, a voice coil 9 is connected to the center of the diaphragm 8, and the middle part of the heis coil 9 is held by a damper 10, and the voice coil 9 is connected to the magnetic field. A copper foil thread wire is fitted into the magnetic gap 11 of the circuit 5 without being eccentric, and the lead wire of the coil of this voice coil 9 is drawn upward along the entire coil bobbin 12, and one end is connected to the terminal 13 provided on the frame 6. The lead-out IJ wire 14 was connected to the coil lead-out island at the top of the coil bobbin 12, and a dust cap 15 was attached to the top of the middle heat section of the diaphragm 8.

In such a general speaker, one person's power +=
In the case of X, it was necessary to add strength to several of the lead wires 14.

As shown in FIG. 2, in a conventional speaker with blood J input specifications, a plurality of holes 16 are provided in the upper part of the coil bobbin 12 of the voice coil 9, and a lead wire 14 is inserted into the six holes 16.
This lead wire 14 is sewn onto the coil bobbin 12 through the other end, and the lead wire 1 of the coil is attached to the other end.
The connection is made by wrapping 7 pieces and applying 18-i, and this connection is fixed with melamine resin or com-based adhesive 19. Outside blood, j input side -: Even if there was, it was extremely dangerous, and when used by one person, everyone would get 1 j or 2 due to the coil hobbin's 4 tatsuyama ha and deflection. Outer lead wire 14 and coil leader wire) 17
Most of the wires were broken inside the melamine It (J resin or com-based adhesive 19) in the concubine part due to solder 18 with the melamine ↑ Y goods and rubber thread J. - Agent 19 and 171I: The function of reinforcing the connection part did not exert any force, but it could be said that it was applied to prevent the connection part from moving when photographing the diaphragm 8, etc. OBJECTS OF THE INVENTION The present invention is intended to eliminate the following drawbacks of the conventional art, and to prevent disconnection at the connection between the lead wire and the lead wire of the coil. SUMMARY OF THE INVENTION In order to achieve all of the above two objects, the present invention has a structure in which a diaphragm is fully connected to the periphery of a frame connected to a magnetic circuit, and the diaphragm is A voice coil is coupled to the center part, and the voice coil is fitted into the magnetic gap of the two magnetic circuits without eccentricity, and a plurality of through holes are provided in the upper part of the voice coil, and the voice coil is connected to the terminal provided in the frame. Insert the lead wire from the voice coil into the through hole and connect it to the lead wire from the voice coil, mold this connection with two-component reaction type instant curing fat [6↑] and connect it to the coil bobbin /ζ
It was designed to strengthen the joints.

・J (Explanation of Embodiment An embodiment of the present invention will be explained below using FIG. 3. The overall structure of the speaker is the same as that explained in the conventional example using FIG. 1. nij′.

Only the features of the present invention will be explained, but J1
V is basically the same as the conventional example shown in FIG. A plurality of through holes 16 are provided in the upper part of the one fill bobbin 12 of the first fill 9, and the through holes 16 are connected to the terminal 13. Ti
The other end of the lead wire 14 to be connected is inserted:
Insert the drawer lead WJ 14 into the coil hobbin 12.
A lead wire 17 is wound from the two coils of the voice coil 9, and electrically connected by applying 21'll'318 to this winding. The configuration in terms of dimensions is no different from the conventional example, however, the present invention is designed to provide a Apply a high viscosity type cyanoacrylate-1 adhesive so as to cover part of the -1 part of the leader line 17 located, and further dilute it with amine compound (%) Freon sweat; liquid, methyl ethyl ketone, a+ton, etc. Warm hardening accelerator'fJ::
So-called two-component J that instantly hardens after forming into 2-3 drops.
The connection part and 0/lead wire 17 are molded with a thermosetting instant-curing resin 20 and fixed with a coil bobbin 121 to form a 414 composition.In addition, the above-mentioned high viscosity type N-anoacryl 1-based adhesive is used. The viscosity of the agent was 6,000 to 10,000 C-pS; it was necessary to take workability into consideration.

It's a hole, except for the molded part made of two-component reaction type instant curing resin 2o, which is the drawer of the lead wire 14.
You can further bond them using melamine resin or 1mm adhesive as in the past, or you don't have to use adhesive to fix them.
('F 7 s nl〃I, all why)
Using the noise and D/N filters, the speaker was simply installed with a conventional melamine resin size rubber adhesive, and the speaker of the present invention was fixed with [a molding made of two-part two-component reaction type instant curing resin]. After making each speaker and examining them, the results were as follows: The conventional speaker was 150W (RMS), but the wire broke near the ``mi'' part between the lead wire and the lead wire after a few hours. Although the voice coil 9 of the speaker of the present invention was carbonized and burnt out between 3ooW (RMS) of approximately 2411.1i, l?1l-ji
Since the speaker of the present invention is configured as described above, there was no occurrence of wire breakage of close to 115%. It is possible to significantly reduce the force resistance, and it is also possible to use a two-component reaction type instantaneously (by applying the resin to the mold, it can be done uniformly in every corner of the mold). It has all the advantages of being highly versatile, short in working time, and can improve productivity, making it of great industrial value.
