Description

headphone

[0001] The present invention relates to headphones.

[0002] 2. Description of the Related Art Conventionally, when headphones are used for a long period of time, a configuration is known in which a head support member is provided to allow the headphones to be worn comfortably (see, for example, Patent Document 1).

[0003] Special Publication No. 2023-524991

[0004] The head support member is a member that comes into contact with the user's head, and may need to be replaced due to deterioration over time, etc. In conventional configurations, there has been a problem in that the head support member cannot be easily replaced.

[0005] The present invention has been made in view of the above points, and has an object to provide headphones with a simple configuration and in which the head support member can be easily replaced.

[0006] One form of headphones of the present invention comprises a pair of speaker units, a headband supporting the pair of speaker units, and a head support member arranged inside the headband, wherein the headband has a plurality of through holes formed at predetermined intervals along the extension direction of the headband, and the head support member has an extension formed at an end of the head support member and passed through the through holes, the extension being removably fixed to the head support member while passed through the through holes.

[0007] A magnet may be provided on a part of the extension, and the extension may be fixed to a part of the head support member by the magnet.

[0008] The extension may be formed in a bag shape, the magnet may be provided inside the bag-shaped extension, and another magnet or magnetic member to which the magnet is attracted may be provided on the part of the head support member.

[0009] The through-hole may be a slit formed in a direction perpendicular to the extension direction of the headband.

[0010] The headband may be attached to the headband such that the extension is inserted from the inside to the outside of the headband into a first through hole among the plurality of through holes, and the extension pulled out from the first through hole is inserted from the outside to the inside of the headband into a second through hole.

[0011] The plurality of through holes may include a plurality of first through holes arranged at a first interval and a plurality of second through holes arranged at a second interval wider than the first interval, and the plurality of first through holes may be formed on the end side of the headband, and the plurality of second through holes may be formed in a central portion of the headband.

[0012] The present invention has the effect of providing headphones that have a simple configuration and allow the head support member to be easily replaced.

[0014] Fig. 1 is a schematic diagram showing headphones according to an embodiment of the present invention. Fig. 2 is a perspective view showing headphones according to an embodiment of the present invention. Fig. 3 is a perspective view of a headband. In Figs. 2 and 3, speaker units (ear cups) are omitted from the illustration.

[0015] As shown in FIG. 1, the headphones S100 include a left speaker unit 10L, a right speaker unit 10R, a headband 20, and a head support member 30.

[0016] The left speaker unit 10L and the right speaker unit 10R are a pair of speaker units formed symmetrically. The left speaker unit 10L and the right speaker unit 10R each have an acoustic element (not shown) that emits sound. The left speaker unit 10L and the right speaker unit 10R cover the left and right ears of the user, respectively, when the headphones S100 are worn on the user's head.

[0017] The headband 20 is a member that supports the left speaker unit 10L and the right speaker unit 10R. As shown in Fig. 1, the headband 20 has, for example, an arc shape when the headphones S100 are viewed from the front. The headband 20 is, for example, an elastically deformable metal plate-like member.

[0018] As shown in Figures 2 and 3, the headband 20 has a plurality of through holes 20h formed therein. In Figures 2 and 3, only some of the plurality of through holes 20h are labeled with reference numerals. The plurality of through holes 20h are formed at predetermined intervals along the extension direction of the headband 20. In this example, the through holes 20h are slits formed in a direction perpendicular to the extension direction of the headband 20. Note that Figure 2 only describes the structure near one end of the headband 20, and the other side has a symmetrical structure, so description thereof will be omitted.

[0019] In this embodiment, the plurality of through holes 20h include first through holes 20h formed in region C1 (see FIG. 3 ) and second through holes 20h formed in region C2. The through holes 20h in region C1 are arranged at a predetermined interval (first interval), and the through holes 20h in region C2 are arranged at a second interval that is wider than the first interval. In this manner, the through holes 20h are formed at relatively narrow intervals in region C1 on the end side of the headband 20, and the through holes 20h are formed at relatively wide intervals in region C2 at the center of the headband 20. This configuration reduces the number of through holes 20h formed in the center of the headband 20, which has the advantage of ensuring sufficient strength in the center.

[0020] (Head pad member) The head support member 30 is a member that comes into contact with the user's head when the headphones S100 are worn on the user's head. The head support member 30 is provided on the headband 20 and is located on the inside of the headband 20. The inside of the headband 20 refers to the side that is closer to the head than the headband 20 when the headphones S100 are worn on the user's head. The head support member 30 is detachable from the headband 20 and can be replaced.

[0021] Fig. 4 shows the head support member 30 in a linearly extended state. Fig. 5 is a cross-sectional view showing the structure of the end of the head support member. As shown in Fig. 4, the head support member 30 has a head support main body 31 and an extension portion 35.

[0022] 5, the head support main body 31 has a configuration in which a long, sheet-like cushion material 33 is disposed inside a pad cover 34. The cushion material 33 may be made of any material, but in this embodiment, urethane foam is used as an example. From the viewpoint of the wearability of the headphones S100, the cushion material 33 is provided in the configuration of this embodiment, but it is not essential for the present invention that the head support main body 31 have elasticity.

[0023] The extension 35 is a strip-shaped portion formed at the end of the head support member 30. Specifically, the extension 35 is provided so as to extend from the end of the head support main body 31. The extension 35 may be composed of a single member or multiple members, but in this embodiment, as shown in Fig. 5, it is composed of a first member 36 and a second member 37. Note that in Fig. 6, the first member 36 and the second member 37 are not distinguished from each other, and the extension 35 is depicted as if it were a single member.

[0024] 5, the first member 36 and the second member 37 are fixed to each other in an overlapping state. The first member 36 and the second member 37 are fixed to each other by, for example, sewing.

[0025] In this example, the second member 37 is formed to be longer than the first member 36. A tip portion 37a of the second member 37 is folded back, so that the end of the extension portion 35 is formed in a bag shape.

[0026] The extension 35 is a portion that is passed through the through-hole 20h of the headband 20, as will be described later. The width dimension w (FIG. 4) of the extension 35 is shorter than the length of the through-hole 20h. The thickness dimension d (FIG. 5) of the tip of the extension 35 is shorter than the width of the through-hole 20h. In the configuration of this embodiment, specifically, the dimension d is longer than the thickness of the portion where the first member 36 and the second member 37 overlap.

[0027] The shape of the through hole 20h may be a quadrangle such as a square or a rectangle. In this case, the width dimension w of the extension portion 35 may be shorter than the length in the width direction of the quadrangle (the same as the extension direction of the slit-shaped through hole 20h). Alternatively, the width dimension w of the extension portion 35 may be longer than the length in the width direction of the quadrangle but shorter than the length of the diagonal.

[0028] As shown in Figures 4 and 5, a first magnet 41 is provided in the extension 35. The first magnet 41 is provided inside the bag-shaped portion of the extension 35. The first magnet 41 is a permanent magnet and has a flat shape. Specifically, the first magnet 41 has a first surface 41a and a second surface 41b. The outline shape of the first magnet 41 may be any shape, such as a circle, a rectangle, or a polygon, but in this embodiment, it is a circle as an example.

[0029] A second magnet 42 is provided near the end of the head support main body 31. Like the first magnet 41, the second magnet 42 is, for example, a flat permanent magnet. The contour shape of the second magnet 42 is also arbitrary, but in this embodiment, for example, it is circular. Specifically, the second magnet 42 has a first surface 42a and a second surface 42b.

[0030] The head support member 30 of this embodiment is configured so that the first surface 41a of the first magnet 41 is attracted to the first surface 42a of the second magnet 42, and the second surface 41b of the first magnet 41 is attracted to the second surface 42b of the second magnet 42. With this configuration, it is possible to either bend the extension 35 in the direction of arrow A and attract the first magnet 41 to the second magnet 42, or bend the extension 35 in the direction of arrow B and attract the first magnet 41 to the second magnet 42.

[0031] Although the second magnet 42 is exemplified in this embodiment, a magnetic member (e.g., iron) to which the first magnet 41 can be attracted may be provided instead of the second magnet 42. Furthermore, means other than a magnet may be used to fasten the extension 35. For example, the extension 35 may be fastened to a part of the head support member 30 by a button, a hook-and-loop fastener, a hook, or the like.

[0032] (Example of wearing the head support member 30) Figure 6 is a cross-sectional view illustrating the state in which the head support member is attached to the headband. For the purpose of explanation, a predetermined through-hole of the headband 20 is shown as a first through-hole 20h-1 in Figure 6. The second through-hole 20h-2 is the second hole from the first through-hole 20h-1, with a third through-hole 20h-3 in between.

[0033] The extension 35 is inserted into the first through-hole 20h-1 from the inside to the outside of the headband 20, and the extension 35 drawn out from the first through-hole 20h-1 is inserted into the second through-hole 20h-2 from the outside to the inside of the headband 20. The extension 35 is then folded back in the direction of arrow A, and the first magnet 41 is fixed to the second magnet 42 in an orientation such that the first surface 41a of the first magnet 41 and the first surface 42a of the second magnet 42 face each other.

[0034] 6 shows only the extension 35 at one end of the head support member 30, the extension 35 at the opposite end is also attached to the headband 20 in the same manner. This fixes the head support member 30 to the headband 20 as shown in FIG.

[0035] 6, the extension 35 is passed through the second through hole 20h-2 instead of the intermediate third through hole 20h-3, but the extension 35 may be passed through the third through hole 20h-3. Also, for example, the extension 35 may first be passed through the second through hole 20h-2 from the inside to the outside (in the direction of arrow B), and then the extension 35 may be passed through the first through hole 20h-1 from the outside to the inside, and the first magnet 41 may be fixed to the second magnet 42 in a state where the extension 35 is bent in the direction of arrow B in FIG.

[0036] Figure 6 illustrates an example in which the extension portion 35 is passed through two through holes 20h, but depending on the shapes of the extension portion 35 and the head support member 30, the extension portion 35 may be passed through only one through hole 20h, and a portion of the extension portion 35 may be fixed to a portion of the head support member 30.

[0037] (Effects of the headphones S100) As described above, in the headphones S100 of this embodiment, the head support member 30 is attached to the headband 20 with the extension 35 of the headband 20 passing through the through-hole 20h. With this configuration, the head support member 30 is not fixed to the headband 20 with screws, and therefore the head support member 30 can be easily replaced with a simple configuration.

[0038] Furthermore, by selecting the through hole 20h through which the extension 35 passes from among the multiple through holes 20h formed in the headband 20 so as to fit the shape and size of the user's head, the fit is improved. A structure in which a component having a through hole corresponding to the through hole 20h is fixed to the headband (which does not have the through hole 20h) and the extension 35 is connected to the through hole of that component is also conceivable, but this structure is disadvantageous in terms of weight reduction. In this regard, according to the present embodiment, the headband 20 has the through hole 20h formed therein, which makes the headband 20 itself lighter, thereby leading to a reduction in the weight of the headphones S100.

[0039] Many support members for general headphones are shaped to contact the user's head at a point. With such a configuration, if the headphones are worn for a long time, uneven pressure can cause pain in the head. In contrast, with the headband 20 of this embodiment, the head support member 30 contacts the head so as to conform to the shape of the head, thereby dispersing pressure on the head, making it suitable for long-term use.

[0040] Furthermore, by replacing the headband with one that is made of a different material, has a different shape, or has different elasticity, the wearing comfort of the headphones S100 can be adjusted to suit the user's preferences. As an example, it is assumed that the headphones S100 will be used while playing sports. In such a case, replacing the headband with a sports headband, for example, can make the headphones S100 more comfortable to use.

[0041] In this embodiment, the extension 35 is fixed to a part of the head support member 30 by a magnet, so that it can be easily attached and detached.

[0042] In particular, because the first magnet 41 is provided inside the bag-shaped extension 35, the portion containing the first magnet 41 can be easily inserted through the through-hole 20h. Figure 7 is a schematic diagram showing an example of a stacked head support member. It is assumed that the fabricated head support member 30 will be housed together during the manufacturing process. For example, by providing a second magnet 42 magnetized in the thickness direction and with different polarities on the first and second surfaces 42a and 42b, even when multiple head support members 30 are stacked as shown in Figure 7, the second magnets 42 do not repel each other, allowing the extension 35 to be neatly organized. This configuration is preferable from the standpoint of ease of handling and transportation of the components. While Figure 7 illustrates the second magnet 42 as an example, the same applies to the first magnet 41.

[0043] In this embodiment, the through-hole 20h is a slit formed in a direction perpendicular to the extension direction of the headband 20. A band-shaped extension 35 is passed through the slit having this shape, and the head support member 30 is fixed to the headband 20 with the extension 35 folded back as shown in FIG. 6. When the headphones S100 are worn, a tensile force is applied to the extension 35 along the extension direction of the head support member 30. Because the slit of the through-hole 20h extends in a direction perpendicular to the direction of this tensile force, the extension 35 is well held within the through-hole 20h without shifting in the length direction of the slit.

[0044] In this embodiment, the head support member 30 is fixed to the headband 20 with the extension 35 passing through the first through-hole 20h-1 and the second through-hole 20h-2. With this configuration, the extension 35 is less likely to come off than in a configuration in which the extension 35 passes through only one through-hole 20h. As a result, for example, the head support member 30 can be fixed even with the first magnet 41 having a relatively low magnetic force, which is advantageous in reducing the weight of the headphones S100.

[0045] Fig. 8 shows a modified example of a head support member. The head support member 30A in Fig. 8 has a hook-and-loop fastener instead of a magnet. Specifically, a first hook-and-loop fastener member 35a is provided on the extension portion 35, and a second hook-and-loop fastener member 31a is provided on the head support main body 31.

[0046] The head support member 30A configured in this manner is attached to the headband 20, for example, by passing the extension portion 35 through the through hole 20h in a manner similar to that shown in Figure 6 and fixing the first hook-and-loop fastener member 35a to the second hook-and-loop fastener member 31a.

[0047] In this example, hook-and-loop fastener members are provided on one side of the head support main body 31 (the side that appears in FIG. 8) and one side of the extension 35 (the side that appears in FIG. 8), but a first hook-and-loop fastener member and a second hook-and-loop fastener member may also be provided on the opposite side (the side that does not appear in FIG. 8). These first hook-and-loop fastener members and second hook-and-loop fastener members may be provided at positions corresponding to the first hook-and-loop fastener member 35a and the second hook-and-loop fastener member 31a, respectively (positions where the members overlap each other in the projection view).

[0048] The present invention has been described above using embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by functionally or physically distributing or integrating in any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiments resulting from the combination also have the effects of the original embodiments.
