Description

[Technical field]

[0001] The present invention relates to a headphone cover that is used between the ear pads of closed type headphones and the ears. [Background technology]

[0002] Conventionally, headphone covers that cover the ear pads of headphones are known. Headphone covers are usually made of thin fabric to allow sound to pass through easily, so there is a problem that the fabric deteriorates due to friction caused by daily use, and the fabric around the opening is particularly prone to tearing. To solve this problem, Patent Document 1 discloses a headphone cover that prevents tearing of the opening periphery by forming the opening periphery from flat rubber that is resistant to friction.

[0003] Patent Document 2 discloses a technology in which a headphone cover has an opening at a sound-passing location on one side of an ear pad, and is provided with a fabric that can be folded back at least 90 degrees from the one side toward the other side, and a core that goes around the periphery of the opening, and the compressive yield stress of the core in the stretching direction is 0.0587 MPa or more.

[0012] <First embodiment>

[0013] FIG. 1 is an explanatory diagram showing a headphone cover 1 according to a first embodiment of the present invention.

[0014] FIG. 1(a) is an explanatory diagram of a headphone cover 1 from above (direction A in FIG. 1(b)). FIG. 1(b) is an explanatory diagram of the headphone cover 1 as seen from the side. FIG. 1(c) is an explanatory diagram of the headphone cover 1 from above (direction C in FIG. 1(b)). As shown in FIG. 1(a), the headphone cover 1 has a circular shape when viewed from above. A through hole 2 is formed in the center. As shown in FIG. 1(b), the headphone cover 1 has an inner end 41 and an outer end 31 (see also FIG. 2). The elastic portion 61 is fixed (joined, fastened, glued, connected, sewn) to the inner end portion 41. In this embodiment, it is applied or glued. Further, the stretchable portion 51 is fixed (joined, fixed, bonded, connected, sewn) to the outer end portion 31. At least the major portion between the inner end portion 41 and the outer end portion 31 is made of the stretchable fabric portion 11. The fabric portion 11 is made of a material that feels good against the skin. Furthermore, fabric portion 11 needs to be made of a highly elastic material that can encase ear pad 101 as described in FIG. 3 and adhere to the ear pad to some degree. Further, the fabric portion 11 has tuck stitches S as shown in FIG. 1 (also see FIG. 4). This tuck stitch S forms an S-shaped portion (constriction) (see Figure 2 and the explanation of the S-shaped portion in Figure 2). This S-shaped portion (constriction) makes it possible to form the entire side so that it has a continuous smooth finish. This tuck stitching S improves (enhances) the fit. This tuck stitching also contributes to maintaining sound quality. In more detail, this S-shape (constriction) eliminates excess wrinkles in the cover fabric, improving adhesion to the pad and reducing deterioration in sound quality. In other words, if wrinkles form between the pad and the fabric, a space will be created that will create an acoustic circuit, changing the sound quality. To eliminate this effect, a smooth, continuous S-shaped portion (constriction) like this is necessary to create a smooth, three-dimensional shape that improves the adhesion between the cover and the pad. In FIG. 1, the number of tuck stitches S is four, and they are formed at 90° intervals as viewed from FIG. 1(a), but this is not limited to this. For example, it is possible to have two lines every 180°, three lines every 120°, five lines, or six lines. Furthermore, the angles between the tuck stitches S do not necessarily have to be the same intervals. For example, even if there are four tuck stitches S, the intervals can be 180°, 60°, 60°, and 60°.

[0015] FIG. 2 is a detailed explanatory diagram of the structure of the headphone cover 1. As shown in FIG. FIG. 2 is an explanatory diagram of an enlarged cross section of FIG.

[0016] As shown in FIG. 2, between the inner end portion 41 and the outer end portion 31, the fabric portion 11 is formed as described above. As shown in FIG. 11, this fabric portion 11 is fixed (fixed, joined, connected, sewn) to the inner end material 21 formed on the inner end portion 41 at a joining surface 33. In this embodiment, it is sewn together. The inner end material 21 may be formed from the same material as the fabric portion 11. In this case, the inner end material 21 constitutes a part of the fabric portion 11. As shown in FIG. 2, the inner end material 21 has a circular disk shape with a through hole 2 formed therein and concentric with the disk. Next, the fabric portion 11 has a third fabric portion 11c having a shape close to a cylinder extending from the through hole portion 2 of the inner end material 21, a first fabric portion 11a having a shape close to a cylinder with a hole that is about 1.5 to 2 times the size of the through hole portion 2, and a second fabric portion 11b whose cross section connecting the third fabric portion 11c and the first fabric portion 11a forms an S-shape as shown in Figure 2. Further, an elastic portion 61 is formed in a doughnut shape (having a crescent-shaped cross section) all around the inside (outer end 31 side) in the axial direction of the inner end material 21 (corresponding to the inner end 41). The "constricted" portion of this S-shape can be woven and knitted from yarn to form the fabric portion 11. In this case, the tuck stitch S may not be necessary. On the other hand, at the position of the outer end portion 31 (the first fabric portion 11a of the fabric portion 11), an elastic portion 51 is formed on the outer periphery side of the cylindrical shape. The stretchable portion 51 is made of a material such as rubber. The stretchable portion 51 can be sewn to the first fabric portion 11 a of the fabric portion 11 . Since the stretchable portion 51 is required to have higher stretchability than the elastic portion 61 (see FIG. 3), it is usually made of a different material from the elastic portion, but it is also possible to make them of the same material.

[0017] Since the fabric portion 11 and the inner end material 21 are formed by sewing (joining, bonding) and the inner end material 21 is simply in the shape of a disk, manufacturing is simplified. This makes it possible to manufacture the device at a lower cost than before, even in manufacturing plants with low technical capabilities. Moreover, the fact that the elastic portion 61 only needs to be adhered to the inner end material 21 also makes manufacturing easier. It is also possible to create an elastic portion 61 and then glue it to the inner end material 21, but it goes without saying that it is easier to manufacture by applying the material that makes up the elastic portion 61 to the inner end material 21, like printing.

[0018] Moreover, the elastic body portion 61 may have a certain degree of flexibility, and may be elastically deformed to be inserted into the recess 102 in the headphones and then return to a shape close to its original shape to enter an engaged state.

[0019] FIG. 3 is an explanatory diagram showing how the headphone cover 1 is attached to the headphones 105.

[0020] Headphones 105 generally include ear pads 101 and an ear pad membrane 103 disposed between a speaker 104 placed deep inside the ear pads 101 . Generally, there is a gap 102 between the ear pad 101 and the ear pad film 103 as shown in FIG. The inner end material 21 (the inner end 41, the elastic portion 61) is elastically deformed and inserted into this gap 102 (FIG. 3(a)). As a result, the headphone cover 1 is engaged (latched). In this state, the outer end portion 31 (fabric portion 11) is stretched and wrapped around the outer periphery of the ear pad 101. As a result, by placing the headphone cover 1 in the state shown in FIG. 3(b), the headphone cover 1 is fixed to the ear pads 101 (headphones 105).

[0021] FIG. 4 is an explanatory diagram of the headphone cover 1 attached to the headphones 105.

[0022] As shown in FIG. 4, the headphone cover 1 is fixed to the headphone 105 in a relatively intimate contact manner, although a certain amount of slack is permitted.

[0023] FIG. 5 is an explanatory diagram of a modified example.

[0024] More specifically, FIG. 5 is an explanatory diagram of a modified example of the inner end material 21. In FIG. The inner end material 21 may be elliptical as shown in FIG. 5, as well as circular. Furthermore, the thickness of the elastic portion 61 fixed to the inner end material 21 may also vary widely. In one embodiment, shown in FIG. 5(a), the width may be quite large. Conversely, as shown in FIG. 5(b), the thickness may be extremely thin.

[0025] FIG. 6 is an explanatory diagram of another modified example.

[0026] The inner end material 21 may be in a rectangular shape as shown in FIG. 6(a) as well as a circle or an ellipse. Furthermore, other shapes such as pentagons, hexagons, polygons with more sides, ovals, etc. may be used. Furthermore, as shown in FIG. 6(b), it is sufficient that the elastic portion 61 is simply fixed to the inner end material 21, and it may be fixed at any position. It is not necessary that the shape be similar to that of the inner end material 21 or the shape of the through hole portion 2 .

[0027] FIG. 7 is an explanatory diagram of still another modified example (elastic body portion 61).

[0028] As shown in FIG. 7(a), the shape (cross section) of the elastic body portion 61 may be any shape. It may be a circle, an oval, a square, etc. Also, as shown in FIG. 7(b), the position at which the elastic portion 61 is fixed may be on the opposite side of the inner end material 21 from the fabric portion 11, or it may be at either the inner end or the outer end.

[0029] <Advanced embodiment> Furthermore, a method of applying anti-slip silicone printing to the surface of fabric portion 11 that comes into contact with ear pad 101 may be used. This prevents misalignment of the ear pads 101, improving the user experience.

[0030] <Configuration and Effects of the Embodiment> The headphone cover 1 covers the ear pad 101 of the headphones 105, and has an inner end 41 that can engage with the ear pad at an internal position of the ear pad 101 and has a through hole 2 in the center, an outer end 31 that can be fixed to the ear pad at an external position of the ear pad 101, and a cloth part 11 between the inner end 41 and the outer end 31, and an elastic part 61 is joined to the inner end 41, so that the inner end 41 elastically deforms and engages with the ear pad. With this configuration, it is possible to provide a headphone cover 1 that is easy to manufacture.

[0031] The inner end portion 41 has a disk-shaped inner end portion material 21 having a through hole portion 2 in the center, and the elastic portion 61 is joined to the inner end portion material 21. With this configuration, it is possible to provide a headphone cover 1 that is easier to manufacture.

[0032] The end of the inner end material 21 on the through hole 2 side is joined to the fabric part 11. With this configuration, it is possible to provide a headphone cover 1 that is easier to manufacture.

[0033] The joining in the present invention includes all methods of joining and fixing (including temporary ones) by adhesion, coating, sewing, crimping, and the like. The structure, materials, connections of the various members, chemical substances, and the like of the present invention can be modified in various ways without departing from the spirit and scope of the present invention. The material can also be freely selected. For example, it is possible to combine two or more components into one, or conversely, it is possible to configure one component from two or more separate components and connect them together. Furthermore, the above embodiment is merely one of the best modes currently available. [Explanation of symbols]
