[Industrial applications]

 The present invention relates to a headband of a headphone, and more particularly to a headphone with a height adjusting mechanism capable of automatically adjusting a relative position between a headphone driver cabinet and a head.

[0002]

[Prior art]

 For headphones, a cabinet with a headphone driver inside is swingably supported at both ends of the headband, and ear pads provided on the outer periphery of the cabinet are applied to the outer circumference of the ears to sandwich both ears by the elastic force of the headband. I was wearing it in this way. When wearing the cabinet, the headphones driver should be installed so that the headphone driver is located approximately in the center of the ear, and the characteristics of the headphone driver should be used for listening. However, the positions of the left and right cabinets had to be adjusted for each person separately.

Therefore, conventionally, there has been used a headphone provided with an adjustment headband inside the headband so as to adjust the height of the cabinet of the headphone independently left and right. In this type of headphones, the position of the adjustment headband can be adjusted by engaging the notch formed in the headband with the engaging portion made of the elastic piece provided at the end of the adjustment headband. Was configured as follows.

[Problems to be solved by the device]

 However, in such an adjusting mechanism, the number of parts is large, adjustment is troublesome, and since it is regulated by the position of the notch, it may be slightly deviated from the optimum position, so that it can be completely adjusted. I didn't go. In other words, the conventional adjustment mechanism has a problem in usability because it is difficult to reduce the cost due to the number of parts, the adjustment is troublesome, and the adjustment cannot be performed completely in some cases.

The present invention has been made in view of the actual situation of the prior art as described above, and an object thereof is to provide a headphone with a height adjusting mechanism, which has a reduced number of parts, is low in cost, and is excellent in usability. To do.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is provided with a cabinet in which a headphone driver is built in at both ends of a headband, and adjusts the relative position of the cabinet and the head inside the headband on the headband side. In a headphone with a height adjusting mechanism having a movable headband, the movable headband is slidably suspended on spring means provided on the headband and lower ends of spring feet extending inside the headband of the spring means. And a plate-shaped abutting member that is configured to come into contact with the head in a state in which the relative distance to the head is automatically adjusted by the opening angle of the spring foot. It is characterized by

[0007]

[Action]

 In the above-mentioned structure, spring means is provided at the portion corresponding to the crown, and the contact member is slidably suspended on the foot of this spring step so that the contact member is first contacted when the headphones are worn. When the member abuts on the head, more specifically on the crown, and when the cabinet is lowered to the position of the ear, the legs of the spring means are opened, and the abutting member and the headband relatively come close to each other. The positions of the two are always defined by the distance from the head of the headband, that is, the height, with the spring interposed. As a result, when the cabinet is located at the center of the ear, the abutting member reliably defines the positions of the two and holds the position by the elastic force of the rod. Therefore, there is no need for an adjusting mechanism, and the height can be automatically adjusted in a stepless manner.

【Example】

 Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

First, the headphone according to the first embodiment will be explained. As shown in the perspective view of the wearing state of FIG. 1 and the front view of FIG. A cabinet 3 attached to the section, a headband 4 having swingable cabinets 3 at both ends, and a movable headband attached to the inside of the headband 4 so as to be suspended by spring means 5. It is mainly composed of 6 and 6.

The cabinet 3 itself is a known one having a headphone driver (not shown) built therein, and the headband 4 is also a known one having a spring plate. The movable headband 6 is supported by the spring means 5 above the center of the headband 4. That is, the spring means 5 has a torsion coil spring 7 attached to the upper center of the headband 4, and a coil house 8 that houses the coil portion of the torsion coil spring 7. The movable headband 6 is suspended from a leg 9 of the torsion coil spring 7 extending inside the headband 4. The coil house 8 is designed so as to be positioned and not to impair the appearance.

As can be seen from FIG. 3, the movable headband 6 has a double structure of an upper contact member 11 and a lower contact member 12. As shown in the perspective view of the main part of FIG. A sliding groove 13 is cut in the contact member 11 of the lower contact member 11 and the bent end portion 9a of the foot 9 is locked in the groove 13 so that the lower contact member 12 and the upper contact member 11 are engaged with each other. It is mounted slidably and non-separably with respect to 11. The foot 9 is loosely inserted into a groove 14 formed in the head band 4 and movably extends inside the head band 4. Further, a head pad (not shown) is provided on the surface of the lower contact member 12 so as to softly contact the head.

The headphone 1 configured as described above is attached to the head 15 by covering the ears as shown in FIG. 1 while opening the headband 4 while holding the cabinet 3 from the initial state where the headphone 1 is not mounted as shown in FIG. Mounting. In this process, the contact member 9 first contacts the crown 16 in the initial state, and as the cabinet 3 is lowered, as shown in the front view showing the usage state in which the main part of FIG. When the movable headband 6 and the headband 4 come close to each other while the coil portion of the spring 7 opens and finally the cabinet 3 is located at the optimum position of the ear, the positions of the two are defined, and in other words, the position thereof. The height of the headband 4 with respect to the crown 16 is maintained. This means that the adjustment is automatically performed without adjusting the height of the headband 4. In addition, this adjustment is also performed steplessly by using a spring, so that it can be easily and snugly fitted to anyone or any shape of head.

Further, unlike the conventional example, it is not necessary to provide a left and right adjusting mechanism for the number of parts, and only the torsion coil spring 7, the movable headband 6, and the coil house 8 are sufficient, so that the cost can be reduced.

FIG. 5 is a main part front view showing a second embodiment which is a modification of the first embodiment. In the second embodiment, the installation direction of the torsion coil spring 21 is set at a direction deviated from the first embodiment by 90 degrees, and the torsion coil spring 21 is arranged inside the headband 4. The other structure is the same as that of the above embodiment. Even with this structure, the same effect can be obtained.

In the above-described first and second embodiments, the movable headband 6 is supported by the torsion coil springs 7 and 21, but a leaf spring formed in a substantially U shape may also be supported. . That is, the apex portion of the substantially U-shaped leaf spring may be attached to the lower surface of the central portion of the headband 4, and the tips of both legs of the leaf spring may be bent at approximately 90 ° as in the first embodiment shown in FIG. . In this case, if the width of the groove 13 is made slightly larger than the width of the leaf spring, and the width of the tip portions of both feet positioned in the groove 13 is made larger than the width of the groove 13, the tip portions of both feet are longer than the length of the leaf spring. All you have to do is bend in the direction.

[Effect of device]

 As is apparent from the above description, in the headphone with the height adjusting mechanism of the present invention, the movable headband is provided on the spring means provided on the headband and the lower end of the spring foot extending inside the headband of the spring means. It consists of a plate-shaped abutting member that is slidably suspended, and this abutting member contacts the head in a state where the relative distance to the head is automatically adjusted by the opening angle of the spring feet. Since it is configured to do so, it is possible to automatically adjust the height steplessly, which can improve usability. In addition, since it is not necessary to provide the parts to be used on the left and right sides, and especially adjusting members such as a lock mechanism are not necessary, the number of parts can be minimized, and the cost can be kept low.
