Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a headset or headphone band device.

(Prior art) Conventionally, a sub-band is provided at a predetermined angle with respect to a main band that supports a speaker, a microphone, etc. at its end, and when in use, for example, the main band is placed on the middle head of the human body, and the sub-band is There are various band devices that can be fitted to the back of the head in a stable manner.

However, in these band devices, the angle between the main band and the sub-band is fixed, or even if the sub-band can rotate with respect to the main band, it is limited to a narrow angle. When applied to a single-ear audio device such as a headset that supports speakers, microphones, etc., if the wearer moves rapidly, shakes his or her head from side to side, or looks down, the weight of the left and right sides may change. Mainly due to this imbalance, the ability to maintain the stability of the worn state during use cannot be said to be sufficient. In particular, with a headset in which both a speaker and a microphone are attached to the main band, if the headset is not properly worn, the microphone may move away from the mouth, causing a problem in which sufficient sound collection cannot be achieved.

(Purpose of the invention) The present invention was made in view of this point, and its purpose is to prevent sudden movements of the wearer's head, especially when applied to one-ear audio equipment. It is an object of the present invention to provide a headset or headphone band device that can maintain stability of its condition.

(Structure of the device) To achieve this purpose, the device has the following structure.

In other words, a main band is provided with a semicircular shape that supports an acoustic unit such as a speaker or microphone at one end, and is bent in a semicircle so as to sandwich the head, and sub-bands with a similar shape are placed at both ends of the main band. The main band is mounted so as to be rotatable at a nearby portion and to adjust the length of an intermediate portion thereof, and the main band is mounted inside the sub-band attachment portion near the end of the main band on the side where the acoustic unit is not attached. 1. A headset or headphone band device, characterized in that a mini-band extending in a direction crossing the main band is slidably attached along the longitudinal direction of the main band.

With this configuration, the sub-band can adjust the length of its intermediate part and rotate with respect to the main band, and the mini-band can move freely, so each band can be attached to the head regardless of its shape or size. Therefore, it will not shift or come off even if the wearer, especially the head, moves suddenly.

(Example) The present invention will be described below with reference to the illustrated embodiments. First, in FIG. 1, 1 is a one-ear headset to which the band device of the present invention is applied, and 2 is its main band. The main band 2 is made of elastic steel, and its middle part has a semicircular shape that surrounds the head. 3 is a support member, and one end of the main band 2 is slidably inserted into the support member 3. A speaker unit 4 is supported by the support member 3, and by moving the support member 3 along the main band 2, the position of the speaker unit 4 relative to the ear can be adjusted. The support member 3 has a rotation support member 3A (see FIG. 2) that rotates around a point on a line passing through the widthwise center of the main band 2, and a hollow convex portion 3B is formed in the rotation support member 3A. ing. A boom 5 is inserted into this hollow convex portion 3B. The boom 5 is rotatable around its axis and slidable in the longitudinal direction with respect to the inner wall of the hollow convex portion 3B, supports a microphone unit 6 at one end thereof, and supports a cord 7 of the microphone unit 6. is passed through it and led out from the other end.

8 is a subband, and this subband 8 is
It is made of the same material as the main band 2 and has substantially the same shape. Reference numerals 9, 10, and 11 designate tubular support members, and the support member 9 is supported by the support member 3 at its intermediate portion on its outer side, and is rotatable relative to the support member 3. The support member 10 is inserted into and fixed to the end of the main band 2 on the side opposite to the side where the support member 3 is located, and the support member 11 has an intermediate portion supported on the outer side of the support member 10. hand,
It is rotatable relative to this support member 10. The sub-band 8 has both ends slidably inserted into the support member 9 and the support member 11, respectively, so that it is rotatable with respect to the main band 2 and the intermediate portion between the support members 9 and 11 is inserted. The length can be adjusted.

Further, a tubular support member 12 is inserted into the main band 2 near the end on the side where the speaker unit 4 is not attached so as to be slidable in the longitudinal direction of the main band 2, and a support member 12 is inserted into the main band 2 so as to be slidable in the longitudinal direction thereof. A support member 13, also tubular, is supported at its intermediate portion. The support member 13 is movable relative to the main band 2, has a slightly curved shape, and has a mini-band 14 slidably inserted thereinto extending in a direction crossing the main band 8. be. This allows the mini band 14 to slide along the longitudinal direction of the main band 2, i.e.
When the headset 1 is worn on the head, it is supported so as to be slidable in the directions of advancing and retracting toward the head (in the directions of arrows A and B in the figure) and in the directions of arrows C and D in the figure. Tubular retaining members 15 and 16 are fitted into both ends of the mini band 14, respectively.

Furthermore, a tubular positioning member 17 is slidably inserted through the main band 2 . And the above-mentioned support members 9, 10,
11, 12, 13, the retaining members 15, 16, and the positioning member 17 are all made of friction members, such as synthetic resin materials.

According to this embodiment configured in this way, when using the device, the main band 2 is first placed on, for example, the middle of the head (the top of the head), and the speaker unit 4 is moved along the main band 2 to fit the ear. let At this time, if the position is determined by the positioning member 17, it becomes easier to readjust the position of the speaker unit 4. On the other hand, the rotation support member 3A is rotated and the boom 5 is moved or rotated in its longitudinal direction to adjust the position of the microphone unit 6 to the mouth. That is, regardless of whether the speaker unit 4 is held in the left or right ear, the boom 5 is provided in a position that is symmetrical to the speaker unit 4, so that the same usage condition can be obtained.

Further, the length of the intermediate portion of the sub-band 8 is adjusted to match the shape and size of the head, and the sub-band 8 is rotated toward the back of the head. Even if it becomes loose during use, the fit can be easily readjusted.

Furthermore, connect the mini band 14 to the speaker unit 4.
Adjust it to any position on the side of the head opposite to where it is. After that, the mini band 14 follows the shape of the head and comes into close contact with the head due to the elastic pressing force of the main band 2 and the sub band 8. As a result, the side of the head on the side where the speaker unit 4 is not located is also held down by the mini band 14.

That is, since each band 2, 8, 14 can be adapted to each part of the head, it can be securely attached to the head, and even if the wearer's head moves suddenly, the speaker unit 4 and microphone unit 6 It is possible to prevent the relative positional relationship between the ear and the mouth from being disrupted as much as possible. Further, since there are friction members in various places on each band 2, 8, 14, the contact friction with the head by the friction members makes the head attachment more reliable.

Since the boom 5, sub-band 8, and mini-band 14 that support the microphone unit 6 can be collapsed relative to the main band 2,
Since it can be compacted when not in use, it has the advantage of not taking up much space.

(Effects of the invention) As is clear from what has been described above, according to the present invention, the stability of the wearing state can be maintained even when the wearer's head moves rapidly, and as a result, the speaker , it is possible to prevent the relative positional relationship of the microphone, etc., with respect to the ear and mouth from collapsing.
