A headband according to an embodiment of the present invention and a headphone including the headband will be described with a headband 51 according to an example and a headphone 52 including the headband.
The headband 51 maintains a stable form unless an external force is applied in each of a first state that is a straight shape in the longitudinal direction and a second state that is curved in an arc shape in the longitudinal direction, State transition is made between both states by applying external force.

FIG. 1 is a perspective view for explaining the overall form of the headphones 52 when the headband 51 is in the first state. Since the headphones 52 cannot be used substantially in this mode, they are hereinafter referred to as non-use modes for convenience.
First, the configuration of the headphones 52 will be described with reference to FIG. 1 showing a non-use state of the headphones 52 and FIG. 2 which is an assembly diagram.

  The headphone 52 includes an elongated headband 51 and main body portions 11 and 12 attached near both ends of the headband 51. The main body portions 11 and 12 are detachable from the headband 51.

The headband 51 includes a plate 1 that is a thin metal thin plate, and a resin cover 2 that covers the plate 1 so as not to be exposed.
The plate 1 has a cross-sectional shape that is a cross-section at the S3-S3 position in FIG. 1 and is curved in the width direction as shown in FIG. Maintain the first state by itself. A side view of the plate 1 in the first state is shown in FIG.

  Further, when an external force such as bending against the bending is applied to the plate 1 in the first state, the cross-sectional shape becomes flat as shown in FIG. 3B, and a predetermined surface in the longitudinal direction. It changes to the 2nd state curved so that 1a may become an outside, and maintains the state itself. Here, the average radius of curvature in the second state is R2v.

  By maintaining the plate 1 in the first state and the second state, the headband 51 is similarly in a non-use state in which the headband 51 is not curved in the longitudinal direction and extends straight, and in a use state in which the headband 51 is curved in the longitudinal direction. Are selectively maintained.

  In the vicinity of both ends of the headband 51, through holes 1b and 1c penetrating through the plate 1 are formed.

As shown in FIG. 2, the main body portions 11 and 12 include housings 11 a and 12 a that house a speaker unit (not shown) therein, and support shaft portions that function as support side members of the ball pivot with a male screw formed at the tip. 11b, 12b.
The housing 11a is supported so as to be swingable (see an arrow) by ball pivot engagement with the support shaft portion 11b. Similarly, the housing 12a is swingably supported by the support shaft portion 12b.

  As shown in FIG. 2, the main body portions 11 and 12 are configured such that the support shaft portions 11 b and 12 b are passed through the through holes 1 b and 1 c from the surface 1 d side opposite to the surface 1 a of the plate 1, respectively. It is attached to the headband 51 by being fastened with screws 14a and 14b.

Cables 13a and 13b having one end connected to each speaker unit are drawn out from the main body portions 11 and 12.
The cables 13a and 13b are combined into one, and a plug 13c for connecting to a music playback device or the like is provided on the other end side to constitute the connection cable 13.
Thereby, the main body parts 11 and 12 output sound toward the lower side (arrow) in FIG. 1 by the audio signal supplied from the music playback device via the connection cable 13.

  When using the headphones 52 described in detail above, as shown in FIG. 5, the headphone 52 is placed on the user's head H in the first state (non-use state) indicated by the alternate long and short dash line, and is attached to both ends of the headband 51. By applying a force that causes the plate 1 to be bent downward with a hand or the like, the bending in the width direction of the plate 1 is released, and the headband 51 changes its state toward the second state.

Here, the average curvature radius R2v of the headband 51 in the second state is set to be smaller than the average curvature radius Rhv in the use state at the head H.
Therefore, in the wearing state of the headphones 52 shown by the solid line in FIG. 2, the headband 51 does not completely reach the second state, and the left and right ears are elastically biased by the main body portions 11 and 12.
Therefore, the headphone 52 does not easily come off from the worn head H, and by appropriately setting the average radius of curvature R2v of the plate 1, the user can use the headphone 52 in an appropriate manner. A good wearing feeling due to the pressure contact feeling can be obtained.

  As described above, the headband 51 and the headphone 52 provided with the headband 51 are in a straight state as a whole when the plate 1 is in the first state. . In addition, since the structure is simple and the number of parts is small, the cost can be reduced. Further, since the structure is simple without having a hinge for folding a conventional headband, it has high durability and is not easily broken.

  The headband 51 may not completely cover the plate 1 with the covering portion 2, or may be a part of the plate 1 exposed. Moreover, the coating | coated part 2 is not provided but you may be comprised only with the plate 1. FIG.

  The embodiment described in detail above is not limited to the above-described configuration, and may be modified in a range not departing from the gist of the present invention.

  Although the headband 51 has been described as having the entire plate 1 covered with the covering portion 2, as a modification, the intermediate portion covering portion 2 excluding the end portions to which the main body portions 11 and 12 are attached is attached to the plate 1. The headband 51A may be replaced with a plurality of passed restriction blocks 21 (hereinafter simply referred to as blocks 21).

FIG. 6 is a partial cross-sectional side view illustrating the headphone 52A in a first state in which the headband 51A extends straight in the longitudinal direction.
In the headband 51A, both end portions to which the main body portions 11 and 12 are attached are covered portions 22 and 23 in which the plate 1 is covered with resin, like the headband 51 of the embodiment.
A plurality of blocks 21 are passed through the range ARa between the covering portions 22 and 23 at both ends of the plate 1 and are generally arranged without a gap therebetween.

  FIG. 7 is a perspective view for explaining the block 21 in a state where the plate 1 is passed. As shown in FIGS. 6 and 7, the block 21 is formed in a flat rectangular tube that is thin in the thickness direction of the plate 1, and the plate 1 is passed through the through hole 21a. The lower surface 21a1 of the through hole 21a is an arcuate curved surface with a central portion protruding in the longitudinal direction.

The end surfaces 21b and 21c of the block 21 are inclined surfaces inclined at a predetermined angle θa so as to taper toward the inner side when the headphones 52A are used.
That is, in a use state in which the headphone 52A is worn on the head, the block 21 has a trapezoidal shape in which the head side is narrowed in a longitudinal sectional shape along the longitudinal direction of the headband 51A.
As shown in FIG. 6, the predetermined angle θa is defined by an angle with an orthogonal plane La that is orthogonal to the plane 1 a when the plate 1 is in the first state and extends in the width direction.

In the above-described headphone 52A, a state in which the headband 51A is curved toward the second state is shown in FIG.
Since the block 21 has a trapezoidal shape in which the end surfaces 21b and 21c on both sides are inclined surfaces and the head side is squeezed in use, when the average radius of curvature of the range ARa becomes small to some extent, The one end face 21b and the other end face 21c come into contact with each other, and the progress of bending is regulated so that the average radius of curvature in the range ARa does not become less than a predetermined value.
In other words, the predetermined angle θa is set to a value corresponding to the desired curvature radius of curvature with respect to the headband 51A, and the block 21 having the angle θa is inserted into the plate 1 to be disposed in the first band of the headband 51A. It is possible to arbitrarily set the average curvature radius R22v that is regulated when being bent toward the two states.

  In the headphone 52A, the average radius of curvature R2v in the form in which the headband 51A is curved in the longitudinal direction can be arbitrarily set according to the shape (angle θa) of the block 21 without replacing the plate 1. Therefore, it is possible to easily obtain a feeling of fitting that fits the shape of the head H of the user.

The covering portions 22 and 23 may be inserted / removed from the end portion of the plate 1, and the block 21 may be replaced by being inserted / removed from the end portion of the plate 1.
Thereby, it is possible to easily achieve the optimum shape of each user on the head H, and it is possible to perform optimum adjustment by the user himself, which is preferable.

Although the main body parts 11 and 12 demonstrated the example made detachable with respect to the headband 51 (51A), you may be fixed with respect to the headband 51 (51A) so that attachment or detachment is impossible.
If the main body parts 11 and 12 are detachable, the main body parts 11 and 12 can be detached and stored in a bag or the like, and this is preferable.
