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 kinds of audio equipment.

[0002]

2. Description of the Related Art With the recent miniaturization of audio equipment,
The space for mounting the speaker is becoming narrower, and it is necessary to make the speaker thinner. Also, with the spread of high-quality sources, it has become essential to use high-quality speakers.

[0003] Such a conventional speaker is shown in FIG.
This will be described below. FIG. 3 is a half sectional view showing the structure of a conventional speaker, in which a magnet 2 is connected to an upper portion of a yoke 1, a plate 3 is connected to an upper portion of the magnet 2, and a magnetic gap 8 is formed between the yoke 1 and the plate 3. The magnetic circuit 4 is formed between them. A frame 5 is connected to the upper part of the magnetic circuit 4, an outer peripheral portion of the diaphragm 6 is connected to a peripheral portion of the frame 5, and a voice coil 7 is connected to a center of the diaphragm 6. The voice coil 7 is fitted into the magnetic gap 8, and the inner peripheral portion of the damper 9 is connected to the middle portion of the voice coil 7 and the outer peripheral portion is connected to the frame 5. And a tinsel wire 12 soldered to a terminal 11 provided on the outside of the wire.

[0004]

However, in the above-mentioned conventional configuration, if the outer diameter of the damper 9 is increased in order to lower the minimum resonance frequency of the speaker, the length of the tinsel wire 12 becomes longer, and as a result, the tinsel wire becomes large. 12 tends to resonate, and the tinsel wire 12 hits the damper 9, the diaphragm 6, etc., and has a problem that abnormal noise is generated.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a high-quality speaker having a wide reproduction band.

[0006]

According to the present invention, there is provided a loudspeaker comprising: a magnetic circuit having a magnetic gap; a frame coupled to an upper surface of the magnetic circuit; and a voice coil which fits in the magnetic gap. And a damper having an inner peripheral portion connected to an intermediate portion of the voice coil and an outer peripheral portion connected to the frame, and a hole provided in a part thereof. And a tinsel wire drawn out of the voice coil and soldered to a terminal provided below the damper through a hole provided in the damper, and the outer diameter of the damper Regardless of the dimensions, the length of the tinsel wire can be shortened, the tinsel wire resonates, and the outer diameter of the damper is increased without hitting the damper or diaphragm, It is possible to lower the minimum resonance frequency of the speaker, the regeneration zone is wide, is capable of providing high quality speaker.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION
A magnetic circuit having a magnetic gap, a frame coupled to an upper surface of the magnetic circuit, a diaphragm coupled to a voice coil that fits into the magnetic gap, and a peripheral edge coupled to an outer periphery of the frame; Pass the lower part of the damper by connecting the inner peripheral part to the middle part of the voice coil and connecting the outer peripheral part to the frame and providing a hole in part and the hole drawn out from the voice coil and provided in the damper. It consists of a tinsel wire soldered to the terminal provided.By passing the tinsel wire through the hole of the damper, the length of the tinsel wire can be shortened, the tinsel wire resonates and the damper and vibration Since it does not hit the plate, it is possible to increase the outer diameter of the damper, lower the minimum resonance frequency of the speaker, and widen the reproduction band.
A high-quality speaker can be provided.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the description, the same parts as in the related art will be described with the same reference numerals.

FIG. 1 is a half sectional view of a speaker according to an embodiment of the present invention, and FIG. 2 is a top view of a damper as a main part.

As shown in FIG. 1, the speaker has a frame 5 connected to an upper portion of a magnetic circuit 4 in which a magnetic gap 8 is formed by connecting a yoke 1, a magnet 2, and a plate 3, and a diaphragm is provided on the periphery of the frame 5. 6, a voice coil 7 that fits into the magnetic gap 8 is connected to the center of the diaphragm 6, and an inner peripheral portion of the damper 9 is connected to an intermediate portion of the voice coil 7. The part is connected to the frame 5 and is composed of a tinsel wire 12 which is pulled out from the voice coil 7, passes through a hole 10 provided in the damper 9, and is soldered to a terminal 11 provided below the damper 9.

As described above, the hole 10 is provided in the damper 9 and the voice coil 7 and the terminal 1 are passed through the hole 10.
Since the tinsel wire 12 is provided between the two, the tinsel wire can be shortened, the tinsel wire 12 resonates, and the damper 9,
It is possible to increase the outer diameter of the damper 9 and reduce the lowest resonance frequency of the speaker without hitting the diaphragm 6 or the like, and to provide a high-quality speaker with a wide reproduction band.

In the above-described embodiment, the holes 10 provided in the damper 9 for passing the tinsel wire 12 are formed in two places and have a circular configuration. However, the present invention is not limited to this. The same effect as that of the present embodiment can be obtained even with an arbitrary number and shape, and it is needless to say that the present invention falls within the scope of the present invention.

[0013]

As described above, since the speaker according to the present invention is constructed, the tinsel wire resonates and the outer diameter of the damper can be increased and the minimum resonance frequency of the speaker can be lowered without hitting the damper or the diaphragm. This makes it possible to provide a high-quality speaker having a wide reproduction band.
