Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to headphones capable of freely changing the direction in which a headband is worn, and is suitable for open-air headphones and vertical headphones.

[0002]

2. Description of the Related Art Conventionally, when listening to music or other audio signals with a reproducing device such as a tape recorder or a receiving device such as a radio, headphones are generally used. The headphone of the hanging type that hangs the headband on the upper side of the head, the headphone of the hanging type that hangs the headband on the lower side of the head, the headphone of the hanging type that hangs the headband on the back side of the head, etc., respectively Exists.

[0003] In addition to the arrangement of a driver unit for headphones that generates sound, in addition to an open-air type headphone in which the driver unit is arranged with the driver's ear facing the side of the ear hole, the driver unit is provided for the purpose of improving the usability. In recent years, a so-called vertical type headphone in which a part or the whole of a driver unit is arranged in a human ear hole and arranged so as to output sound toward a front side of a head has been used in recent years.

[0004]

However, from the viewpoint of convenience of use by the user, it is desired to use the headphone for the overhang type, the front type, and the rear type, but the direction in which the headband is worn is changed. As you do
Since the direction in which the cord extending from the driver unit protrudes changes, there has been no headphone that can be used for these types.

[0005] Further, in a vertical type headphone, not only the direction of the cord is changed but also the direction of the driver unit is changed and the direction of sound output is changed in accordance with the change of the direction in which the headband is applied. The hanging direction could not be changed substantially.

The present invention has been made in order to solve the above-mentioned drawbacks, and has as its object to provide a headphone that can freely change the direction in which a headband is applied.

[0007]

According to a first aspect of the present invention, there is provided a headphone in which a housing accommodates a driver unit for generating sound, and a pair of rotatable indirect portions is formed by a band-shaped headband and a housing. The headband supports the housing via these members, which are located therebetween and are respectively disposed with the intermediate member interposed therebetween.

[0008] Therefore, since the pair of indirect portions, each of which is rotatable, is located between the headband and the housing, even if the direction in which the headband is hung on the human head is changed, it is adjusted accordingly. By rotating the housing with respect to the headband by the pair of joints, the orientation of the driver unit with respect to the human head can be kept constant at all times. As a result, it is possible to obtain a headphone in which the direction in which the cord protrudes from the housing can always be constant, and the direction in which the headband is worn can be freely changed without changing the direction of sound output even in the case of vertical headphones.

Further, even when the lengths of the headbands do not match, by rotating the pair of indirect portions, the lengths of the headbands are adjusted, so that the adjustment of the length of the headband becomes unnecessary. In particular, along with changing the direction in which the headband is hung on the human head, it is necessary to adjust the length of the headband, but since a pair of indirect portions are arranged with the intermediate member interposed therebetween, Even when the direction in which the headband is hung is changed, it is not necessary to adjust the length of the headband by rotating the pair of indirect portions while changing the tilt direction of the intermediate member.

The headphone according to the second aspect has the same configuration as the first aspect, but further operates as follows. In the present invention, one of the pair of joints has a configuration in which the housing is rotatable around the housing.

Therefore, the housing rotates with respect to the headband and the intermediate member only by rotating only the indirect portion enabling the housing to rotate around the housing of the pair of indirect portions. Similarly to the above, the direction of the driver unit with respect to the human head can be kept constant at all times.

The headphone according to the third aspect has the same configuration as that of the first aspect, but further operates as follows. The present invention has a configuration in which the intermediate member is disposed outside the headband.

Therefore, since the intermediate member is arranged outside the headband, the headband follows the human temporal region, and the headband can be put on the ear like a vine of glasses. By putting the headband on the ear, the headband can be stably fixed to the head.

[0014]

FIG. 1 shows an embodiment of the present invention.
To FIG. 9 and the embodiment of the present invention will be described based on these drawings.

As shown in FIGS. 1 to 3, the headband 12 of the headphone 10 according to the present embodiment is formed in an arc-shaped and band-like shape over which a human head H is wound. An adjusting mechanism 14 for adjusting the length is provided.

At both ends of the headband 12, there are arranged a pair of intermediate members 16 as a pair of intermediate members which can adjust the tilt while rotating in the figure. A first indirect portion 18 which is a hinge for rotatably connecting the upper end of the connecting arm 16 to the headband 12 is formed on the upper end of the pair of connecting arms 16.

Further, at the lower ends of the pair of connecting arms 16, second joints 20 for rotatably supporting a housing 22 made of synthetic resin are formed, respectively.
A pair of connecting arms 16 are connected between the pair of housings 22 and the headband 12, respectively.

That is, to the pair of second joints 20, the distal ends of a not-shown rotation shaft connected to the pair of housings 22 are rotatably mounted, respectively. In addition, a pair of housings 22 are supported by a pair of second joints 20, respectively.

The housing 22 has a driver unit 24 composed of a coil, a diaphragm and the like (not shown).
Is built in and stored. A cord 26 connected to a device such as a tape recorder or a radio (not shown) is attached to the outside of the housing 22. For this reason, the diaphragm of the driver unit 24 vibrates to generate sound based on an electric signal transmitted from a device such as a tape recorder or a radio via the cord 26.

On the other hand, the driver unit 24 built in the housing 22 is arranged as shown in FIGS. The direction in which the driver unit 24 generates sound is the direction of the arrow P shown in FIGS. 1 and 5, and is relative to the axis L shown in FIG. They are almost orthogonal. That is, in FIG. 4, the direction is perpendicular to the paper surface. Generally, headphones 10 of the present embodiment are vertical headphones.

Next, the headphones 10 according to the present embodiment will be described.
The operation of will be described. Driver unit 2 that produces sound
4 is accommodated in a housing 22, and a pair of indirect portions 18 and 20, which are rotatable, respectively, are
Arm 1 which is located between the
6 are interposed. Therefore, the headband 12 is connected to the pair of housings 22 via these members.
Respectively.

Further, the second joint portion 20 of the joint portions 18 and 20 supports the housing 22 so as to be rotatable around an axis L which is the housing 22 itself.

Therefore, the pair of indirect portions 18 and 20 which are respectively rotatable include the headband 12 and the housing 22.
Therefore, even if the direction in which the headband 12 is hung on the human head H is changed, the housing 22 is rotated with respect to the headband 12 by the pair of indirect portions 18 and 20. By doing so, the direction of the driver unit 24 with respect to the human head H can be kept constant at all times.

As a result, the direction in which the cord 26 protrudes from the housing 22 can always be kept downward and constant, and the direction in which the headband 12 is worn can be freely changed without changing the direction of sound output.
Is obtained.

Further, a headband 1 for the human head H
With the change of the hanging direction of 2, the headband 1
The length of the connecting arm 16 needs to be adjusted. However, since the pair of indirect parts 18 and 20 are arranged with the connecting arm 16 interposed therebetween, even when the direction in which the headband 12 is hung is changed, By rotating the pair of joints 18 and 20 while changing the
Adjustment of the length of 2 becomes unnecessary.

In this embodiment, a pair of indirect parts 1
8 and 20, the second joint 20 enables the housing 22 to rotate around the housing 22.
The housing 22 can be rotated with respect to the headband 12 and the connecting arm 16 by simply rotating only 0, so that the direction of the driver unit 24 with respect to the human head H can be always constant. That is, the driver unit 24 can always be arranged toward the front side of the human head H by simply rotating only the second indirect portion 20.

More specifically, as shown in FIGS. 6 and 9A, the headband 12 can be put on the upper side of the human head H, and the driver unit 24 generates a sound at this time. The sound direction P, which is the direction, can be on the front side of the head H. Also, by rotating the housing 22 about the axis L, the state in which the headband 12 is hung on the front side of the head H as shown in FIGS.
As shown in (C), the sound direction P can be set to the front side of the head H even when the headband 12 is hung on the rear side of the head H.

At this time, as shown in FIG. 8, there is a difference between the distance A from the ear canal to the top of the head and the distance B to the back of the head.
The difference AB can be absorbed by positioning the joint portion 18 in front of the ear canal. Thereby, there is no need to operate the adjustment mechanism 14, and the operability is improved.

Further, as another embodiment, a structure in which a pair of connecting arms 16 are arranged outside the headband 12 as shown in FIG. By arranging the connecting arm 16 outside the headband 12 in this manner, the headband 12 follows the human head H, and as shown in FIG. The band 12 can be put on the ear E, and the headband 12 can be fixed to the head H more stably by putting the headband 12 on the ear E.

In the above-described embodiment, the direction in which the driver unit 24 generates sound is substantially perpendicular to the axis L around which the housing 22 rotates, but the direction in which the driver unit 24 generates sound. May be simply a direction intersecting the axis L around which the housing 22 rotates.

Further, in the above-described embodiment, the description has been made using the vertical type headphones. However, the present invention may be applied to headphones of a type in which the driver unit is arranged toward the back of the ear hole.
