DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relatively large headphone, and more particularly, to a headphone which is light and comfortable to wear and has a good wearing feeling with less disturbing hair.

[0002]

2. Description of the Related Art Headphones include a pair of headphone units having a built-in transducer (electro-acoustic conversion means) for converting an electric signal into an acoustic signal, and a pair of headphone units provided at both ends of the headphone unit. And a headband made of an elastic body curved to cover the top of the head for applying the lateral pressure.

In such a configuration, a headband capable of applying a strong lateral pressure is used to reliably support the headphone unit at the position of the ear with the headband. Feeling too strong and wearing headphones for a long time can be painful.

In order to eliminate this feeling of pressure, a head mechanism or a hanger thereof is provided with a click mechanism for adjusting a substantial length, and after the headphones are put on the head, the head mechanism is moved by the click mechanism. Some have adjusted the length to just fit the size of the user's head.

[0005] In the case of introducing this mechanism, the headphone unit can certainly be supported by a weak lateral pressure, and even if it is used for a long time, it does not cause much pain. It was necessary to readjust it, and it was troublesome to use.

Further, the mechanism itself is complicated and the cost is high. Furthermore, even if there is a part that fits best between clicks during the adjustment, the position cannot be selected, so that further pursuit of comfort may cause dissatisfaction.

Therefore, in order to eliminate the need for such adjustment,
Some have introduced a head support. The head support is intended to position the headphone unit and the ear relative to each other inside the headband and to provide the headband with a function of only applying a side pressure. .

As one type, a free adjust type is known in which a rubber belt is inserted into a headband and both ends of a leather belt provided inside the headband are elastically supported by the rubber belt. I have.

[0009]

According to the above-mentioned type, when wearing headphones, the leather belt is pushed by the top of the head, whereby tension is applied to the rubber belt, and the tension is converted into the side pressure of the headband. The headphone unit is positioned and supported by an appropriate force.

[0010] However, it is necessary to push up the leather belt by the top of the belt, and this causes the hair to be disturbed. In addition, since a rubber belt is used, there is a problem in durability.

Further, the leather belt comes into contact exclusively with the top of the head and the temporal side is opened, so that a just-fit feeling cannot be obtained. In addition, since the top of the head is pressed by the leather belt, it is undeniable that a feeling of oppression remains even with a weak force.

As described above, even in the case of using the head support of this kind, there still remain problems in mounting properties, usability, and durability.

[0013] The present invention has been made in view of the circumstances of the prior art, and its object is to provide wearability, usability, and the like.
An object of the present invention is to provide headphones that are excellent in durability and that do not cause hair disorder.

[0014]

According to the present invention, there is provided a pair of headphone units having electro-acoustic conversion means for converting an electric signal into an acoustic signal and supported at a position facing an ear. And a headband connected between the headphone units to apply lateral pressure to the headphone unit, and a head support inside the headband and directly in contact with the head to support the headphone unit. in the headphone, the head support member is formed of a plate material having elasticity, pairs headband in a position facing the temporal and parietal region side as a free end perilla

Further, the above object has an electro-acoustic conversion means for converting an electric signal into an acoustic signal, and a pair of headphone units supported at a position facing the ear, and connected between the headphone units, In a headphone comprising a headband for applying lateral pressure to the headband and a head support inside the headband and directly in contact with the head and supporting the headphone unit, the head support is made of an elastic plate material. It is also achieved by being formed and attached to the casing of the headphone unit so that the top side is a free end.

On the other hand, another feature of the present invention is that it has electro-acoustic conversion means for converting an electric signal into an acoustic signal, and has a pair of headphone units supported at a position facing the ear, and connected between these headphone units. In a headphone comprising a headband for applying lateral pressure to each of the headphone units and a head support for directly abutting on the head and supporting the headphone unit, the head support is formed from an elastic plate material. The headband unit is attached to the casing of the headphone unit such that the top side is a free end, and the headband is positioned and connected along the head side except for the top part.

[0018]

As described above, the head support is attached to the headband.
On the other hand , according to the configuration that can be displaced and cantilevered, when the headphones are put on the head, the head support abuts from the temporal region along the top of the head and according to the shape of the head It is elastically deformed and just fits with light force.

At this time, since the portion facing the top of the head is vacant, the disturbance of the hair is suppressed to a minimum and the feeling of oppression is reduced. In addition, since the head support is made of an elastic plate, durability does not matter.

Further, according to the structure in which the head support is attached to the casing of the headphone unit, the headphone unit and the head support wrap the portion from around the auricle to the temporal region. Thus, the side pressure of the headband can be further reduced, and a softer wearing feeling can be obtained.

Further, by connecting and connecting the headband along the side of the head excluding the top of the head, the headband can be shortened in its substantial length to contribute to a reduction in the overall weight. It is also effective in preventing falling off, and it is also possible to make the surroundings of the face from the front side of the human body at the time of wearing clear.

[0022]

[Example] First, with reference to FIGS. 1 to 3 will be described first embodiment of the present invention. That is, the headphones according to the embodiment include a pair of headphone units 1 and 2.
1 and a hanger member 2 between the headphone units 1 and 1
a, a headband 2 which is swingably connected via 2a
And a pair of head supports 3, 3 cantilevered inside the headband 2.

In this case, the headphone unit 1 may be a known one, and a headphone driver (not shown) including a transducer for converting an electric signal into a voice is housed in a casing 4 thereof. The ear pad 5 is provided on the peripheral portion facing the.

The headband 2 is made of a substantially U-shaped plate-like elastic material, and swingably engages via a hanger member 2a so that the headphone unit 1 can be pressed against the ear and held. Thus, the lateral pressure can be reliably applied regardless of the contact angle of the headphone unit 1 with the ear.

The head support 3 is made of an elastic synthetic resin plate such as polypropylene. In this embodiment, the head support 3 is wider than the headband 2 and has a stronger curvature .

[0026] Moreover, the head support 3 is the head of the user.
In order to be able to adjust according to the shape, the fixed end 8 side
Can be rotated with respect to the headband 2 via the rotation support 11
Noh is attached.

Referring to FIG. 3 showing a cross section taken along the line AA of FIG . 1, the rotation support portion 11 is provided on the inner side surface of the end portion of the bed band 2 on the opposite end side of the head band 2. A pair of support pieces 12, 12 formed so as to be parallel to each other, and a pair of flange pieces 13, formed so as to enter between the support pieces 12, 12 on the fixed end 8 side of the head support 3. 13 and a rotating shaft 14 for connecting the support piece 12 and the flange piece 13 so as to be relatively rotatable.

In this case, the support piece 12 and the flange piece 1
3 have moderate elasticity, and the flange pieces 1
The members 3 and 13 are fitted so that a predetermined frictional force is generated in the support pieces 12 and 12. Although not shown, a male screw is cut at one end of the rotary shaft 14, and a knob 15 as a nut is screwed to the male screw.

[0029] Thus, by loosening the knob 15, you can adjust the angle of the head support member 3 freely, by tightening the knob 15 supporting piece 12 of the flange members 13
, The head support 3 can be held at that angle.

[0030] Another example of the rotation supporting portion 11 of the head support member 3 is shown in FIGS. 4-6. In this example, a pair of support pieces 1 is attached to the end of the headband 2 as described above.
2 and 12 are provided, and a pair of flange pieces 13 and 13 are formed on the fixed end 8 side of the head support 3.

The support piece 12 and the flange piece 13 are relatively rotatably connected to each other by a rotary shaft 16. In this case, a coil spring 17 is attached to the rotary shaft 16.

[0032] One end of the coil spring 17 is the winding end 17
a acts on the headband 2 side and the other end 17b acts on the head support 3 side, so that the head support 3 rotates such that its free end 7 side rotates toward the head of the user. Be energized.

[0033] Thus, the head support 3, according to this
Is displaced according to the user's head shape, and a just-fit feeling is obtained. In this case, as shown in FIG. 6, the corner 12a of the support piece 12 serves as a stopper for the fixed end 8 of the head support 3, thereby restricting the initial position of the head support 3. .

FIG . 7 shows still another example of the adjusting means of the head support 3. According to this, the slide member 20 is provided between the fixed end 8 of the head support 3 and the end of the headband 2, and the head support 3 is slid toward the user's temporal region, thereby enabling use. It is possible to arbitrarily set an appropriate lateral pressure for the user.

In this example, the slide member 20 includes a concave portion 21 formed on the end side of the headband 2 and a concave portion 2
A boss 22 provided on the fixed end 8 side of the head support 3 so as to be slidably fitted to the head support 1, a male screw 23 inserted into the recess 21 from outside the headband 2, The position of the head support 3 can be arbitrarily adjusted by operating the knob 23 a of the male screw 23, comprising a female screw hole 24 formed in the boss 22 so as to screw with the screw 23.

Further , in any of the above cases, the head support 3 is provided so as to oppose the position from the temporal region to the top of the head band 2 and opposes near the lower part of the temporal region at the lower end. Is attached to the headband 2 at a position where the headband 2 is fixed, and this position is supported as a fixed end 8 in a cantilever manner.
It can be freely elastically deformed.

When the headphone thus constructed is put on the head, the head support 3 abuts on the portion from the temporal to the top of the head, and the headphone unit 1 is in a state of just fitting to the shape of the head. , And an appropriate weak lateral pressure is applied from the headband 2 to securely hold the headphones.

At this time, since the portion of the head support 3 facing the top of the head is vacant, the feeling of oppression is weakened. You can concentrate on

In addition, disturbance of the hair can be minimized.
Further, since the head support 3 is formed of an elastic synthetic resin material (which may be a metal material), there is almost no problem in durability as in a rubber band or the like.

It should be noted that the headband 2 can be made lighter by integrally molding it with a synthetic resin material such as polypropylene having the same elasticity, and it is not necessary to introduce a complicated mechanism such as a click mechanism. A headphone with a small number of parts, light weight, easy mounting, and low cost can be provided.

In each of the above embodiments, the head support 3 is attached to the headband 2. However, as shown in FIGS. 8 and 9, the head support 3 is attached to the casing 4 of the headphone unit 1. You may make it attach.

In this example, the head support 3 is integrated with the casing 4 on the cover 4b side.
A pad 3 a attached to the surface of the head support 3 facing the head is connected to the ear pad 5.

[0043] According to this, the headphone unit 1 together are Ategawa around the auricle through the ear pad 5, head support 3 that is continuously provided on the casing 4
It is supported by a large area extending from the temporal region to the crown via the, so that the mounting surface can be widened. Therefore, the side pressure of the headband 2 can be further reduced, and the feeling of wearing is further improved.

The head support 3 may be integrally attached to the casing body 4a. The pad 3a may be provided separately from the ear pad 5.

[0045] FIGS. 10 to 12, in addition to it is possible to contribute to a reduction in the weight of the total weight by shortening the substantial length of the headband 2 is also effective dropout prevention during mounting, and further, at the time of mounting 1 shows an embodiment of a headphone capable of refreshing around the face from the front side of a human body.

[0046] In other words, the headphones according to the embodiment,
A pair of headphone units 1 and 1, a headband 2 that is swingably connected between the headphone units 1 and 1 via hanger members 2a and 2a, and a plate material having elasticity, the top side of which is free.

The headband 2 is made of a plate-like elastic material which is bent in an arc shape, as is apparent from the plan shape shown in FIG. 12 , and holds the headphone unit 1 against the ear. The headphone unit 1 is swingably engaged via the hanger member 2a so that the side pressure can be reliably applied regardless of the contact angle of the headphone unit 1 with the ear. In addition, the headband 2 with respect to the casing 4
The specific positional relationship can be freely determined as long as it is located along the head side except for the top of the head, for example, when the headphone is worn, for example, when it is attached to the back of the head. Further, if necessary, it can be attached so as to be located below the chin.

Although not shown, the headband 2 in this case is not limited to a plate shape, but may be made of a rod-shaped elastic material. It may have a structure directly connected without interposing the hanger member 2a.

The head support 3 is made of an elastic synthetic resin plate such as polypropylene. In this embodiment, the head support 3 is wider than the headband 2 and has a stronger curvature, and a pad 3a is attached to the side facing the head. I have. Each of the head supports 3 has one end fixed to the casing 4 and the other end forming a free end 7 near the top of the head, so that the head support 3 can be freely elastically deformed.

For this reason, according to the headphones shown in FIGS. 10 to 13 , since the headband 2 connects the headphone units 1 and 1 so as to go around the back of the head, the headband 2 goes around the top of the head. The substantial length can be shortened as compared with the case, and it can contribute to the reduction of the total weight.

In addition, at the time of mounting, the head support 3 and the head band 2 can be supported from two directions by arranging them at different positions with respect to the head.
Even if there is a violent movement, it can be effectively prevented from falling off. In addition, when the wearing state is viewed from the front side of the human body, the headband 2 is hidden behind the back of the head, so that a clear impression can be given without being noticed.

[0053]
