DESCRIPTION JPH1146399
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
speaker used in various audio equipment.
[0002]
2. Description of the Related Art A conventional speaker will be described with reference to FIG.
FIG. 3 is a half sectional view showing the structure of a conventional speaker, in which a lower
plate 1 having a center pole portion 8, a ring-shaped magnet 2 and a ring-shaped upper plate 3
are laminated and bonded by an adhesive. A magnetic circuit having a gap 9 is formed, and the
frame 4 is adhesively bonded to the upper surface of the magnetic circuit.
[0003]
The diaphragm 5 has its outer periphery fixed to the periphery of the frame 4 with an adhesive
and has its inner periphery adhesively bonded to the voice coil 7 supported by the damper 6. The
voice coil 7 is inserted into the magnetic gap 9 without eccentricity by the damper 6.

Further, the sub cone 10 is attached to the upper surface of the central portion of the diaphragm
5 for the purpose of preventing the entry of foreign matter from the outside into the magnetic
gap 9. Further, a lead wire 11 is connected to the end of the voice coil 7, and the other end of the
lead wire 11 is connected to a terminal 12 coupled to the frame 4.
[0005]
When a current is generated in the voice coil 7 by supplying a signal current to the terminal 12
from the outside, the voice coil 7 operates in the vertical direction by the driving force according
to Fleming's left hand law by the magnetic flux generated in the magnetic gap 9 Then, the
diaphragm 5 coupled to the voice coil 7 is driven to radiate the gas compression wave into the
space, thereby performing electrical / mechanical / acoustic energy conversion and producing
sound.
[0006]
SUMMARY OF THE INVENTION In the above-described speaker, a drying time is required to use
an adhesive when assembling the magnetic circuit, the diaphragm 5 and the like, and the
organization of the assembly process is also complicated. It was
Also, when there is a problem with the completed speaker, it takes time to disassemble and repair
it.
[0007]
An object of the present invention is to solve the above-mentioned problems, to reduce the use of
the adhesive during the manufacturing process and to provide a speaker that is easy to
disassemble and repair.
[0008]
[Means for Solving the Problems] In order to solve the above problems, the speaker according to
the present invention comprises a resin molding frame divided longitudinally into at least two, a
voice coil and an inner periphery coupled to the voice coil. A voice coil / diaphragm integrated
component formed by the diaphragm, a magnetic circuit mounting portion mounted with a
magnetic circuit having a magnetic gap into which the voice coil is fitted, and the frame at least
on the respective frames. A first insertion guide into which the outer periphery of the diaphragm

is fitted and a second insertion guide into which at least a part of the magnetic circuit mounting
portion is fitted under the respective frames are provided with the diaphragm and the magnetic
circuit. It is not necessary to apply an adhesive between the frames, and it is possible to separate
the frames so that the speaker can be easily disassembled and repaired.
[0009]
The invention according to claim 1 of the present invention is a resin molded frame divided into
at least two longitudinally, a voice coil and a diaphragm in which the inner periphery is coupled
to the voice coil. And a magnetic circuit mounting portion mounted with a magnetic circuit
having a magnetic gap into which the voice coil is fitted, and the frame at least on the respective
frames of the frame. A first insertion guide in which the outer periphery is fitted and a second
insertion guide in which at least a part of the magnetic circuit mounting portion is fitted under
the respective frames are provided, and between the diaphragm and the magnetic circuit and the
frame It is not necessary to apply the adhesive of the above, and it is possible to make the frame
detachable so that the speaker can be easily disassembled and repaired.
[0010]
Hereinafter, an embodiment of a speaker according to the present invention will be described
with reference to FIGS. 1 to 2B.
[0011]
FIG. 1 is a side sectional view of a loudspeaker according to an embodiment of the loudspeaker of
the present invention, FIG. 2 (a) is an exploded view, and FIG. 2 (b) is a perspective view thereof.
According to the figure, 16 is a magnetic circuit mounting portion on which the center pole
portion 13, the ring-shaped magnet 14 and the ring-shaped upper plate 15 are stacked and
mounted, and 17a and 17b are divided frames divided in the vertical direction. In the direction,
the first insertion guides 18a and 18b, the third insertion guides 19a and 19b, and the second
insertion guides 20a and 20b are provided in the divided frames 17a and 17b, respectively.
Reference numeral 21 denotes a voice coil-diaphragm-damper integrated product in which the
diaphragm 21a, the voice coil 21b and the damper 21c are integrated in advance.

Next, the assembly of the speaker will be described. The periphery of the diaphragm 21a of the
voice coil / diaphragm / damper integrated component 21 is made the first insertion guide 18a
and the periphery of the damper 21c is made third based on the divided frame 17a. The insertion
guide 19a is fitted, a part of the periphery of the magnetic circuit mounting portion 16 is
inserted into the second insertion guide 20a, and then the first insertion guide 18b, the third
insertion guide 19b, and the second insertion of the divided frame 17b. The diaphragm 21a
corresponding to the guide 20b, the damper 21c, and a part of the peripheral edge of the
magnetic circuit mounting portion 16 are inserted and the divided frames 17a and 17b are
integrated by known means (such as adhesion and welding) to constitute a speaker. .
[0013]
In addition, since the magnetic circuit, the voice coil, the diaphragm and the damper integrated
product 21 can be easily taken out by separating the divided frames 17a and 17b, the defective
portion can be corrected extremely easily, and the respective parts are conventionally connected.
The amount of adhesive used can be reduced.
[0014]
Further, in the above embodiment, the magnetic circuit portion fits the peripheral edge of the
magnetic circuit mounting portion 16 on which it is mounted into only the second insertion
guides 20a and 20b, but as is also deduced from FIG. The entire part may be guided by the
divided frames 17a and 17b.
[0015]
As described above, according to the present invention, the diaphragm and the magnetic circuit
mounting portion are inserted into the first and second insertion guides provided on the resin
molding frame which is vertically divided into at least two parts, and the speaker is provided. To
eliminate the need for applying an adhesive between the diaphragm or the magnetic circuit and
the frame, thereby reducing the amount of adhesive used in the process and providing a speaker
that can be easily disassembled and repaired because the frame can be separated. It is.
