DESCRIPTION JPH0550894
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
electroacoustic transducer diaphragm used for an electroacoustic transducer.
[0002]
2. Description of the Related Art A conventional diaphragm will be described based on FIGS. 3 to
5. FIG. FIG. 3 is a plan view of a diaphragm in the prior art. In the figure, reference numeral 1
denotes a diaphragm which is provided with holes 2 for passing voice coil lead wires.
[0003]
FIG. 4 is a cross-sectional view of a diaphragm and a voice coil bobbin for explaining drawing of a
voice coil lead wire. The diaphragm 1 is the same as that shown in FIG. A voice coil bobbin 6 is
attached to the back of the diaphragm 1. The voice coil 7 is wound around the voice coil bobbin
6. The voice coil lead 7 a from the voice coil 7 is drawn to the front side of the diaphragm 1
through the hole 2.

FIG. 5 is a perspective view of a diaphragm. First, the voice coil lead wire 7a from the voice coil 7
is drawn through the hole 2 provided in the diaphragm 1 to the front side of the diaphragm 1
(see FIG. 4). The voice coil lead wire 7 a drawn to the front side of the diaphragm 1 is formed.
The formed voice coil lead wire 7 a is connected and fixed to the lug 8. Finally, the hole 2 is
closed with an adhesive or the like. If necessary, the voice coil lead wire 7a is also fixed by an
adhesive or the like so as not to move.
[0005]
However, in the conventional diaphragm for electroacoustic transducer, the voice coil lead wire
forming is carried from the hole provided in the diaphragm to the lug through the voice coil lead
wire. Has the following problem. In this case, it is difficult to insert the voice coil lead wire into
the hole of the diaphragm, or the voice coil lead wire may be twisted to form a wire, which may
lead to disconnection of the lead wire in a power test or the like. .
[0006]
The present invention has been made in view of the foregoing points, and the voice coil lead wire
can be easily routed, and the voice coil lead wire can be prevented from being twisted into a
dango shape. It is an object of the present invention to provide a diaphragm for an
electroacoustic transducer having a structure for
[0007]
SUMMARY OF THE INVENTION In order to solve the above problems, a diaphragm for an
electroacoustic transducer according to the present invention is a vibration for an electroacoustic
transducer used for an electroacoustic transducer such as a microphone, a speaker, and an
earphone. The plate is characterized in that a slit is provided from the hole provided in the
diaphragm to the outer periphery or the inner periphery of the diaphragm.
[0008]
Another electroacoustic transducer diaphragm according to the present invention is an
electroacoustic transducer diaphragm used for an electroacoustic transducer such as a
microphone, a speaker, and an earphone, wherein a lead wire provided on the diaphragm is used.
It is characterized in that a slit is provided from the hole for passing through to the outer
periphery or the inner periphery of the diaphragm.

[Operation] The slit is provided from the hole provided in the diaphragm to the outer periphery
or the inner periphery of the diaphragm, and the voice coil lead wire from the voice coil is
provided in the diaphragm via the slit provided in the diaphragm Bring it to the hole.
Therefore, there is no work of piercing, the voice coil lead wire can be easily routed, and there is
a risk that the voice coil lead wire may be twisted.
[0010]
Embodiments of the present invention will be described below with reference to the drawings.
First, a first embodiment will be described based on FIG.
In the figure, 1 is a diaphragm and 2 is a hole. A slit 3 is provided between the hole 2 and the
outer periphery of the diaphragm 1. The slit 3 is provided to facilitate the routing of the voice
coil lead wire. That is, as a work procedure, the voice coil bobbin can be placed in the magnetic
circuit gap via a jig, and the diaphragm 1 can not be fixed to the voice coil bobbin. Therefore, as
shown in FIG. 4, a voice coil bobbin is attached to the back of the diaphragm 1 in advance. This is
because the diaphragm 1 is not provided with a space at the center, and therefore the jig can not
be pulled upward.
[0011]
In the processing of the voice coil lead wire, the voice coil lead wire from the voice coil mounted
on the back of the diaphragm 1 is brought into the hole 2 through the slit 3. At this time, the
notch 4 may be provided on the outer periphery of the diaphragm 1 by guiding the slit 3.
Normally, the holes 2 and the slits 3 are filled with an adhesive or the like after the wire drawing
of the voice coil lead wire is completed. In some cases, this slit 3 is not filled with an adhesive or
the like, and the internal pressure of the unit is released to help prevent deformation and protect
the diaphragm. Therefore, it is also effective to reduce the number of work steps.

Next, a second embodiment will be described based on FIG. In the figure, 11 is a diaphragm, 2 is
a hole, and 5 is a hole provided at the center. A slit 13 is provided between the inner periphery of
the hole 2 and the diaphragm 1. The slits 13 are provided to facilitate the routing of the voice
coil lead wires. That is, as a work procedure, a voice coil bobbin is placed in a magnetic circuit
gap via a jig, and a voice coil lead wire from this voice coil bobbin is brought close to the center
and stood up. The diaphragm 11 and the voice coil are fixed via the voice coil lead wire.
[0013]
The processing of the voice coil lead wire is brought from the hole 5 at the center of the
diaphragm 1 to the hole 2 through the slit 13. At this time, the notch 4 may be provided on the
inner periphery of the diaphragm 11 by guiding the slit 13. Although the dome-shaped
diaphragm is described in the drawings, the present invention can be applied to a cone-shaped or
other diaphragm.
[0014]
As described above, the diaphragm for the electroacoustic transducer according to the present
invention is provided with slits from the holes provided in the diaphragm to the outer periphery
or the inner periphery of the diaphragm, so that the voice coil The voice coil lead wire can be
brought to a hole provided in the diaphragm through a slit provided in the diaphragm. Therefore,
there is no work of piercing, the voice coil lead wire can be easily routed, there is no risk of
twisting the voice coil lead wire, and the work man-hours can be reduced and the quality can be
improved.
