DESCRIPTION JP2003078983
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
headphone having a shape that is mounted by hanging an arm extended from a headphone main
body on the top of the pinna.
[0002]
2. Description of the Related Art Conventionally, as a headphone, for example, one having a
shape shown in FIG. 18 has been put to practical use. FIG. 18 is a side view of the headphone, in
which the arm 2 extends upward from the left housing 1 and is connected to the opposite right
housing not shown. Inside the housing 1, a driver unit driven by an audio signal supplied via a
cable 4 is incorporated, and an ear pad 4 is attached to the outside of the housing 1.
[0003]
In the case where the headphone of the shape shown in FIG. 18 is constructed, the headphone is
constructed with a simple structure having a relatively small number of parts by integrally
molding the housing 1 and the mounting portion of the arm 2 with resin. Can.
[0004]
However, when the housing 1 and the mounting portion of the arm 2 are integrally formed of
resin, when mounting the housing 1 with resin, the mounting portion of the arm 2 and the
10-05-2019
1
housing 1 The housing 1 needs to be cut away at the overlapping portion, and when the ear pad
3 formed of a relatively soft sponge-like resin or the like is attached, a recess 3a corresponding
to the cutout portion of the housing 1 is generated Resulting in.
[0005]
The reason why this dent occurs is that, when the housing 1 and the mounting portion of the arm
2 are integrally molded of a synthetic resin, the shape in the vicinity of the integrally molded
housing 1 is, for example, as shown in FIG. It will be shown.
19A shows the back surface, FIG. 19B shows the side surface, and FIG. 19C shows the front
surface. A driver unit (not shown) is disposed on the back surface shown in A of FIG. 19 and the
ear pad 3 is attached. In the assembled state, the surface shown in FIG. 19C is exposed to the
outside.
[0006]
Here, as shown in A and C of FIG. 19, a flange 1a for attaching the ear pad 3 is formed in a
substantially annular shape on the housing 1, and the ear pad 3 is put on the flange 1a. Thus, the
ear pad 3 is attached.
However, in order to form the housing 1 and the mounting portion of the arm 2 integrally, the
flange 1 a can not be provided at a position overlapping the mounting portion of the arm 2.
[0007]
That is, in this example, as shown in B of FIG. 19, the molding die is divided into the core side and
the cavity side on the basis of the parting line P, and resin molding is carried out. In order to
form the portion, the flange 1a can not be formed in a portion overlapping with the position (a
range in which a so-called undercut occurs). Accordingly, the position where the arm 2 overlaps
the arm 2 is a state in which there is no member for supporting the ear pad 3, and a recess 3a as
shown in FIG. 18 is generated.
10-05-2019

[0008]
As the molding die, the simplest upper and lower pushing-off structure is adopted here, and a
flange can be formed in the undercut portion by using a more complicated die such as a slide die.
Although not impossible, molding using such a complex mold has the problem of increasing the
manufacturing cost, and the price of headphones is high.
[0009]
Depending on the shape of the ear pad 3, the recess 3a can be made inconspicuous, but even in
that case, if the corresponding portion of the ear pad 3 is pushed, it will be easily recessed
because there is no flange.
In addition, when the listener wears, the absence of the flange at the corresponding portion
causes the ear pad 3 to be partially recessed, which may cause discomfort in the contact with the
pinna. In addition, the occurrence of such a recess 3 a makes it easy for the ear pad 3 to be
detached from the housing 1. Furthermore, when the ear pad 3 is deteriorated due to a change
with time, there is a problem that the ear pad 3 is easily torn from that portion.
[0010]
As another problem, in the housing of this type of headphone, it is necessary to pass a cable for
externally supplying an audio signal or the like to the driver unit housed inside. Here, when the
cable attached to the headphone is pulled by any force from the outside, the force is directly
applied to the connection portion between the driver unit and the cable so that the cable is not
detached from the driver unit. In the middle, it was necessary to provide a mechanism to stop the
cable.
[0011]
That is, for example, it is assumed that a circular housing 8 shown in FIG. 20 is prepared, and a
driver unit for outputting an audio signal is accommodated in the inside 8a of the housing 8. At
this time, a through hole 8 b is provided on the side surface of the housing 8 formed of resin, and
the cord 9 is allowed to pass through the through hole 8 b. One end of the cord 9 through the
10-05-2019
3
through hole 8b is soldered and connected to the driver unit inside the housing 8, and in this
example, even if the cord 9 is pulled from the outside, the cord 9 and the driver In order to
prevent the soldered portion from being cut off, a portion 9a where the cord 9 is once connected
is formed on the inner side of the housing 8, and even if the cord 9 is pulled from the outside, it
is connected The point 9a is caught in the through hole 8b so that no force is applied to the
soldering point or the like.
[0012]
With this configuration, the cord can be prevented from being broken. However, when
assembling the headphone, it is necessary to pass the cord 9 through the through hole 8b of the
housing 8, and the portion 9a connected to the cord itself There is a problem that the work of
forming the is necessary and the assembling is very time-consuming.
[0013]
An object of the present invention is to solve the problems in constructing such headphones.
[0014]
SUMMARY OF THE INVENTION According to the present invention, a driver unit driven by an
audio signal and a driver unit are housed inside, and a first flange portion for mounting an ear
pad outside is provided on the outer periphery. And a second flange connected to the first flange
portion on the housing side when connected to the housing as an arm in a headphone provided
with the housing and an arm connected to the housing and hooked to the upper rear of the pinna
A part is provided.
[0015]
According to the present invention, by providing the flange portion connected to the flange
portion on the housing side on the arm side connected to the housing, the so-called undercut in
resin molding of the housing can be obtained. By arranging the flange portion, the flange portion
for mounting the ear pad is formed substantially annularly, and the ear pad can be held well.

flanges and the like can not be seen from the outside at all. Therefore, even if the housing 110
and the arm 130 are made of different materials, they are noticeable There is no such thing.
Also, even if the material constituting the housing 110 and the arm 130 is a material that is
difficult to print or paint, only the cap 120, which is a component that stands out from the
outside, can be made of a material that can be easily printed or painted. The cap may be printed
or painted to enhance the productability, and the design as a headphone can be improved with a
simple configuration.

According to the present invention, by providing the flange portion connected to the flange
portion on the housing side on the arm side connected to the housing, the flange portion for
mounting the ear pad is formed substantially annularly. It will be done.
That is, even if it is difficult to form a flange portion on the housing side at a position overlapping
the arm connection portion in order to provide the arm connection portion in the housing, the
flange portion on the arm side is positioned at that position. As a result, the ear pad can be held
well in a substantially annular shape. Therefore, there is no discomfort at the time of wearing due
to the partial absence of the flange portion, and damage such as tearing of the ear pad can be
10-05-2019

effectively prevented.
[0060]
In this case, the housing has an eaves projecting from the housing of the driver unit on the outer
side, and when the housing and the arm are connected, the second flange is located substantially
inward of the eaves. Since the connection portion between the housing and the arm is located at
a position hidden by the eaves, the connection between the housing and the arm is not
noticeable.
[0061]
Also, when the housing and the arm are connected by providing a convex portion or a concave
portion, which is fitted when connected, at the end of the first flange and the end of the second
flange. Each flange part is fitted in a convex part or a recessed part, and becomes an integral
shape, and becomes a suitable shape as a flange part for ear pad mounting | wearing.
[0062]
Also, by providing a hole or groove into which the end of the arm is inserted on the inner surface
of the housing to which the driver unit is attached, it is easy and reliable to attach the arm to the
housing using the hole or groove Can do it.
[0063]
Further, when the housing is provided with a hole or a groove into which the end of the arm is
inserted, the end of the arm inserted into the hole or the groove is connected to the inner surface
of the housing. By providing the convex portion or concave portion to be fitted at the same time,
the connection state between the housing and the arm can be well maintained by the fitting of
the convex portion or concave portion.
[0064]
Further, by providing a projection or a groove for fixing the driver unit on the inner surface of
the housing to which the driver unit is attached, the driver unit can be easily fixed to the housing.
[0065]
Further, when the projection or groove for fixing the driver unit is provided on the housing side
as described above, the projection or groove for fixing the driver unit is also provided on the
10-05-2019
17
second flange side of the arm. Since the driver unit is held even on the arm side integrated with
the housing, the driver unit can be held better.
[0066]
In addition, the first flange portion of the housing is provided with a cut portion for passing a
cord whose one end is connected to the driver unit, so that the cord for supplying an audio signal
etc. to the driver unit can be easily passed. Will be able to
