DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker used for various sounders.

[0002]

2. Description of the Related Art In recent years, it has become indispensable for the industry to conserve resources and prevent industrial waste from being generated due to global environmental problems and the like.

A conventional speaker will be described below with reference to the drawings. FIG. 4 is a half sectional view showing a conventional speaker of this type.

In FIG. 4, a frame 2 and a terminal 3 are connected to a magnetic circuit 1, and a voice coil 5 having a gold wire 8 and a damper 6 produced in a separate process as shown in FIG. Is inserted into the magnetic gap 4, the damper 6 is fixed to the frame 2, then the diaphragm 7 is fixed to the voice coil 5 and the frame 2, and the connection between the terminal 3 and the gold wire 8 is made to have the slack size of the gold wire 8 and the forming shape. Were adjusted, and the extra thread was cut off from the gold wire 8. Finally, the dust cap 9 was fixed to the upper surface of the central portion of the diaphragm 7.

[0005]

However, in the above-mentioned conventional construction, when the gold wire 8 is joined to the terminal 3, the required slack corresponding to the amplitude of the diaphragm 7 is added to the gold wire 8 to form the wire. Therefore, it is necessary to provide some dimensional allowance. After the joining, the extra dimension was cut and discarded by providing an extra line cutting step for the gold thread 8.

Therefore, in the conventional configuration, an extra line cutting step for the gold wire 8 must be provided, and the extra line of the cut gold wire 8 must be treated as industrial waste.
There was a major problem in increasing production costs and saving resources.

The present invention solves such a conventional problem,
The purpose of the present invention is to reduce the cost of parts and work processes and eliminate the generation of industrial waste.

[0008]

In order to solve the above-mentioned problems, a speaker according to the present invention has a terminal joined to a gold wire of a voice coil in advance, and when the terminal is swaged to a frame, the length of the gold wire is determined. The terminal mounting hole of the frame is formed into an elongated hole so that the shape can be formed, and a frame is used in which the crimping position of the terminal can be arbitrarily adjusted.

[0009]

With the above construction, the gold coil wire of the voice coil is joined to the terminal without cutting off the extra line in advance, and the length and the shape of the gold thread wire are formed on the frame provided with the long hole, and the swaging position is determined. Since it is possible to fix and fix the gold wire, it is not necessary to provide an extra wire cutting step, and no industrial waste of the extra gold wire is generated.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a half sectional view showing a structure of a speaker according to the present invention, FIG. 2 is a half sectional view showing an assembly of a voice coil, a terminal and a damper to which a gold wire is joined, and FIG.
2 is a half bottom view of the speaker according to the present invention shown in FIG.

In FIG. 1, a magnetic circuit 11 has a frame 1
2, and the gold wire 18 of the voice coil 15 and the terminal 13 are joined without cutting off the gold wire 18 in a separate step as shown in FIG.
And the assembly of the terminal 13 and the damper 16 are prepared. Then, the voice coil 15 is fitted into a magnetic gap 14 formed in the magnetic circuit 11 and the outer peripheral portion of the damper 16 is fixed to the frame 12. Next, the mounting position of the terminal 13 is determined while adjusting the length and shape of the gold wire 18 in the elongated hole-shaped terminal mounting hole 20 provided in the frame 12 in consideration of the amplitude of the diaphragm 17. And fixed by caulking. A diaphragm 17 is fixed to the outer periphery of the frame 12, and a dust cap 19 is fixed to the center of the diaphragm 17 to form a speaker. FIG. 3 is a half bottom view for making the elongated terminal mounting hole 20 provided in the frame 12 of the speaker according to the present invention described with reference to FIG. 1 easier to understand.

With the above-described configuration, the terminal 13 can be inserted into the terminal mounting hole 20 of the claim 12 such that the length and the shape of the gold wire 18 become the optimum values without cutting off the extra length of the gold wire 18. The mounting position can be adjusted and fixed.

Therefore, the step of cutting off the gold wire can be eliminated, and no industrial waste of the gold wire cut off is generated.

[0014]

As described above, the speaker according to the present invention has the following features.
A long hole-shaped terminal mounting hole that allows the mounting position to be adjusted arbitrarily is provided on the frame, and the gold wire and terminal of the voice coil are fixed without cutting off the gold wire, and the length and shape of the gold wire are fixed. Since the structure is such that it can be fixed to the terminal mounting hole of the frame while adjusting it to the optimum value, the wire thread cutting process can be eliminated, and no industrial waste of the wire cutting wire is generated.

As described above, the present invention can simultaneously reduce the production cost during speaker production and prevent the deterioration of the global environment by taking measures against the generation of industrial waste, and its industrial value is extremely large. .
