Description

Technical Field

[0001] This application relates to the technical field of electronic products, and particularly to a headband structure and headphones.

Background Art

[0002] Headphones are currently commonly used earphones, usually including a headband structure and ear cups. After wearing, the two ear cups sandwich the user's ears and play audio for the user to listen to. This type of earphone has advantages such as being able to reduce damage to hearing and having good acoustic effects, so it is widely favored by people.

[0003] For headphones, the clamping force of the headband structure is an important design parameter of such headphones. For example, if the clamping force is too large and cannot be adjusted to an appropriate size, when the user wears it for a long time, local fatigue may occur at the wearing part of the human body, and there is a possibility of causing local discomfort and pain to the user's head. As a result, the comfort during wearing of the earphone is reduced.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Based on this, in view of the problem that the clamping force of the headband structure is too large when wearing conventional headphones, resulting in a reduction in the comfort during wearing of the headphones, this application provides a headband structure and headphones including the headband structure that can adjust the clamping force of the headband structure to improve the comfort during wearing of the headphones.

The upper housing assembly and the lower housing assembly are each arc-shaped in their length directions. The headband structure is provided, wherein the upper housing assembly includes an upper housing, the upper housing is connected to the side of the lower housing assembly facing away from its own arc center, and both ends of the upper housing facing away from the lower housing assembly have a first arc-shaped structure, the first arc-shaped structure is convex in the width direction of the upper housing assembly, and the top of the upper housing facing away from the lower housing assembly has a planar structure, the planar structure extends flat in the width direction of the upper housing assembly.

[0006] In one embodiment, a mounting space is formed between the upper housing and the lower housing assembly, a support strip with higher toughness than the upper housing is provided within the mounting space, and the opposing ends of the support strip are connected to the opposing ends of the lower housing assembly, respectively.

[0007] In one embodiment, the upper housing assembly further includes an upper protective cover and an upper elastic strip, wherein the upper protective cover covers the side of the upper housing facing away from the lower housing assembly, and the upper elastic strip is provided between the upper protective cover and the upper housing, with one end of the upper elastic strip attached to the upper protective cover and the other end attached to the upper housing.

[0008] In one embodiment, the upper elastic strip includes a first elastic strip and a second elastic strip that are in close contact with each other, wherein the hardness of the first elastic strip is less than that of the second elastic strip, and the side of the first elastic strip that is backward from the upper housing is attached to the upper protective cover, and the side of the second elastic strip that is backward from the first elastic strip is attached to the upper housing.

[0009] In one embodiment, the length of the first elastic strip is greater than the length of the second elastic strip, and both ends of the first elastic strip facing the upper housing are attached to the corresponding first arc-shaped structure, the side of the second elastic strip facing the upper housing is in close contact with the planar structure, and the side of the second elastic strip facing away from the upper housing and the first arc-shaped structure are flush with each other.

[0010] In one embodiment, both ends of the upper housing facing the lower housing assembly have a second arc-shaped structure, and the second arc-shaped structure is a recessed arc relative to the lower housing assembly in the width direction of the upper housing assembly, thereby forming a sliding space for accommodating a sliding member in the second arc-shaped structure and the lower housing assembly.

[0011] In one embodiment, the lower housing assembly includes a lower housing, a lower protective cover, and a lower elastic strip, wherein the lower housing is connected to the upper housing, the lower protective cover encloses the side of the lower housing facing away from the upper housing, and the lower elastic strip is provided between the lower protective cover and the lower housing, with one side of the lower elastic strip attached to the lower housing and the other side attached to the lower protective cover.

[0012] In one embodiment, the lower elastic strip includes a third elastic strip and a fourth elastic strip that are in close contact with each other, wherein the length of the third elastic strip is shorter than the length of the fourth elastic strip, and the hardness of the third elastic strip is greater than the hardness of the fourth elastic strip. The side of the third elastic strip facing away from the fourth elastic strip is attached to the lower housing, and the side of the fourth elastic strip facing away from the third elastic strip is attached to the lower protective cover. The surface of the lower housing attached to the lower protective cover and the side of the fourth elastic strip facing away from the third elastic strip are flush with each other.

[0013] In one embodiment, mounting holes are formed at both opposing ends of the lower housing, and guide sleeves are fitted into each of the mounting holes. The guide sleeves allow a sliding member to pass through, so that a part of the sliding member is exposed to the outside of the headband structure.

[0014] According to another aspect of the present application, headphones are provided, comprising a headband structure as described in any of the above aspects, wherein sliding members movable relative to the headband structure are provided at both ends of the headband structure, and each sliding member is provided with an earmuff. [Effects of the Invention]

[0015] The above headband structure is formed by partially removing the top of the upper housing assembly on the side facing the lower housing assembly, thereby forming a first arc-shaped structure at both ends of the upper housing on that side, and a planar structure at the top of that side. The first arc-shaped structure is a convex arc in the width direction of the upper housing assembly, and the planar structure extends flat in the width direction of the upper housing assembly. As a result, the upper housing, in which the planar structure is formed after the top is partially removed, can reduce the clamping force of the headband structure due to the reduction in material compared to a structure in which the top of the upper housing is not partially removed. Therefore, a support strip with higher toughness can be attached to the lower housing to support the upper housing, providing more clamping force through the support strip. The high toughness of the support strip allows the clamping force to be adjusted over a wide range, and as a result, the user can adjust the clamping force to an appropriate size when wearing the headphones. Furthermore, it can improve comfort during wear by avoiding localized discomfort or pain on the head caused by excessive clamping force of the headband structure. [Brief explanation of the drawing]

[0023] One embodiment of the present invention provides a headband structure and headphones including the headband structure, the headband structure clamps onto the user's head so that the user can wear the headphones and listen to audio.

[0024] The configuration of the headphones and headband structure in this application will be described below. This embodiment is merely illustrative and does not limit the technical scope of this application. In other embodiments, the headband structure of this application is not limited to use with headphones, but can be applied to any product that needs to be worn on the head, and is not particularly limited here.

[0025] As shown in Figures 1 to 3, Figure 1 shows a front view of a part of the structure of headphones according to one embodiment of the present invention, and Figure 2 shows a schematic perspective view of a part of the structure of headphones. The headphones according to the embodiment of the present invention include a headband structure 10, and sliding members 40 are provided at both ends of the headband structure 10, and earmuffs (not shown) are provided on each sliding member 40, and the headband structure 10 is an arc-shaped elongated structure that is worn on the user's head, and after the user puts on the headband structure 10, the two earmuffs clamp the user's head, thereby allowing the user to listen to audio, and the sliding members 40 are movable relative to the headband structure 10, and by adjusting the overall length of the headphones, the headphones can be adapted to users with different head shapes.

[0026] As shown in Figures 3 and 4, Figure 3 is a plan view of the headband structure 10, and Figure 4 is a cross-sectional view of the headband structure 10 in the direction AA in Figure 3. In the embodiment shown in Figure 4, the headband structure 10 includes an upper housing assembly 100 and a lower housing assembly 200, both of which are arc-shaped structures in their respective longitudinal directions (direction X in Figure 1). The lower housing assembly 200 is in contact with the user's head, and the upper housing assembly 100 and the lower housing assembly 200 are connected to each other to assemble into a complete headband structure 10.

[0027] Specifically, in one embodiment, as shown in Figures 4 and 5, the upper housing assembly 100 includes an upper housing 110, an upper protective cover 120, and an upper elastic strip 130, wherein the upper housing 110 is connected to the side of the lower housing assembly 200 that is backward from its own arc center, the upper protective cover 120 covers the side of the upper housing 110 that is backward from the lower housing assembly 200 and extends to both ends of the upper housing 110 and conforms to the overall arc shape of the upper housing 110, and the upper elastic strip 130 is provided between the upper protective cover 120 and the upper housing 110, with one side of the upper elastic strip 130 attached to the upper protective cover 120 and the other side attached to the upper housing 110, so that the upper protective cover 120 also wraps around the upper elastic strip 130.

[0028] In a preferred embodiment, the upper housing 110 is made of plastic, and since the plastic material has a certain hardness, elasticity, and toughness, the upper housing 110 can form the main frame of the upper housing assembly 100 and provide a certain clamping force, thereby allowing the headband structure 10 to grip the user's head, and the clamping force of the upper housing 110 can be adjusted by curving the upper housing 110 to different arcs, allowing the user to have a more comfortable feeling when wearing the headphones. The upper protective cover 120 is made of leather to protect the upper housing 110 and serves to improve the decorative aesthetics, and the upper elastic strip 130 also has great elasticity and is made of sponge to support the upper protective cover 120, thereby allowing the upper protective cover 120 to better wrap around and cover the upper housing 110.

[0029] Furthermore, the material of the upper housing 110 is not limited to plastic, but may be a tough metal material such as stainless steel or aluminum; the material of the upper protective cover 120 is not limited to leather, but may be soft artificial leather or plastic; and the material of the upper elastic strip 130 is not limited to sponge, but may be any material with high elasticity; there are no particular limitations here.

[0030] Furthermore, considering that prolonged wear of headphones can cause excessive clamping force, potentially leading to localized discomfort or pain on the user's head, to appropriately adjust the clamping force of the headphones, the clamping force of the upper housing 110 is weakened. In an improved embodiment, as shown in Figure 6, a portion of the top of the upper housing 110 facing the lower housing assembly 200 is shaved off, reducing the material of the upper housing and thereby weakening the clamping force of the upper housing 110.

[0031] Specifically, after a portion of the top of the upper housing 110 facing away from the lower housing assembly 200 is removed, both ends of the upper housing 110 facing away from the lower housing assembly 200 have a first arc-shaped structure 111, and the top of the upper housing 110 facing away from the lower housing assembly 200 has a planar structure 112. As shown in Figures 6 and 7, the first arc-shaped structure 111 has a convex arc shape in the width direction of the upper housing 110 (the Y direction shown in the figures), and the planar structure 112 extends flatly in the width direction of the upper housing 110. In this way, after measurement with an instrument, the clamping force of the upper housing 110 is reliably smaller than that of the conventional structure, and as a result, comfort during wear can be improved.

[0032] After a portion of the top of the upper housing 110 facing away from the lower housing assembly 200 was trimmed, adaptive improvements were made to the structure of the upper elastic strip 130 in order to maintain the overall aesthetics of the upper housing assembly 100 and to meet the user's requirements for the appearance of the headphone product. Specifically, as shown in Figures 4, 5, 8, and 9, the upper elastic strip 130 includes a first elastic strip 131 and a second elastic strip 132 that are in close contact with each other, with the side of the first elastic strip 131 facing away from the upper housing 110 being attached to the upper protective cover 120, and the second elastic strip 13 The side of the second elastic strip 132 facing away from the first elastic strip 131 is attached to the upper housing 110, more specifically, the length of the first elastic strip 131 is greater than the length of the second elastic strip 132, so that both ends of the side of the first elastic strip 131 facing away from the upper housing 110 are attached to a corresponding first arc-shaped structure 111, the side of the second elastic strip 132 facing away from the upper housing 110 is in close contact with the planar structure 112, and the side of the second elastic strip 132 facing away from the upper housing 110 and the first arc-shaped structure 111 are flush with each other in the arc direction of the first arc-shaped structure 111.

[0033] In some embodiments, the length of the second elastic strip 132 is equal to the length of the planar structure 112, thereby ensuring that after the second elastic strip is brought into close contact with the planar structure, the first arc-shaped structure 111 is formed as a smoothly transitioning arc-shaped structure, and also facilitating close contact with the first elastic strip 131.

[0034] In this way, after a portion of the top of the side of the upper housing 110 facing away from the lower housing assembly 200 is shaved off, the elastic strip is divided into two parts, the first elastic strip 131 and the second elastic strip 132. This allows for saving radial dimensions of the upper housing assembly 100. Furthermore, after the second elastic strip 132 is attached to the planar structure 112, the radii of the second elastic strip 132 and the radii of the first arc-shaped structure 111 transition smoothly. As a result, the side of the upper housing assembly 100 facing away from the lower housing assembly 200 has a large radii, ensuring that the product conforms to the product appearance standards required by the user.

[0035] Preferably, the hardness of the first elastic strip 131 is lower than that of the second elastic strip 132, so that the first elastic strip 131 is softer and more easily wrapped around the upper protective cover 120, while the second elastic strip 132 is harder than the first elastic strip 131 and more easily maintains the overall appearance of the upper housing assembly 100.

[0036] Of course, in other embodiments, the lengths of the second elastic strip 132 and the first elastic strip 131 may be matched, with the middle portion of the second elastic strip 132 facing the lower housing assembly 200 in close contact with the planar structure 112, and both ends of the second elastic strip 132 facing the lower housing assembly 200 in close contact with a corresponding first arcuate structure 111, thereby achieving a similar effect.

[0037] Furthermore, the elasticity of plastic materials is subject to high demands regarding material properties and the environment. After prolonged use, the elasticity of the plastic material deteriorates significantly, causing a large decrease in the overall clamping force of the headband structure 10. Additionally, due to the low toughness of the plastic material, it becomes difficult to significantly adjust the clamping force after it has decreased considerably. As a result, the headphones tend to come loose when the user is wearing them.

[0038] Stainless steel offers greater toughness than plastic, and allows for adjustment of clamping force within a wide range. When the clamping force weakens, the toughness of the stainless steel can be used to increase it. However, because stainless steel is difficult to process, it results in very high manufacturing costs for headband structures 10, which have high requirements for their external shape.

[0039] Therefore, in order to resolve the contradiction between manufacturing cost and the adjustment range of clamping force, the headband structure 10 further includes a support strip 300 which has higher toughness than the upper housing 110, as shown in Figures 4, 5, and 8, based on the above embodiment, and the support strip 300 is in the shape of a simple arc. At the position where the support strip 300 is positioned, a mounting space 11 is formed between the upper housing 110 and the lower housing assembly 200, and the support strip 300 is provided within the mounting space 11, with the opposing ends of the support strip 300 connected to the opposing ends of the lower housing assembly 200, respectively. On the one hand, the support strip 300 can support the upper housing 110, and on the other hand, the magnitude of the clamping force can be adjusted by curving the support strip 300 and the upper housing 110 to different arcs.

[0040] At the same time, a portion of the top of the upper housing 110 facing away from the lower housing assembly 200 is machined away, allowing more clamping force to be provided by the support strip 300. Since the toughness of the support strip 300 is higher than that of the upper housing 110, the clamping force can be adjusted over a wide range, mainly due to the high toughness of the support strip 300. As a result, the clamping force of the headband structure 10 can be adjusted over a wide range to ensure a stable clamping force while guaranteeing the appearance required by the user, and manufacturing costs can be kept down.

[0041] In a preferred embodiment, the material of the support strip 300 is stainless steel, and the material of the upper housing 110 is plastic. Of course, the support strip 300 and the upper housing 110 may be made of any material having elasticity and toughness, provided that the toughness of the support strip 300 is higher than that of the upper housing 110.

[0042] As shown in Figures 10 and 11, in a more preferred embodiment, both ends of the upper housing 110 facing the lower housing assembly 200 have a second arc-shaped structure 113, the second arc-shaped structure 113 being a recessed arc relative to the lower housing assembly 200 in the width direction of the upper housing assembly 100, thereby forming a sliding space 101 for accommodating a sliding member 40 in the second arc-shaped structure 113 and the lower housing assembly 200, the sliding member 40 being slidable within the sliding space 101, thereby adjusting the length of the sliding member 40 exposed to the outside of the headband structure 10, and further adjusting the overall length of the headphone product, thereby accommodating various head shapes and meeting the usage needs of more users.

[0043] In the upper housing assembly 100, the upper protective cover 120 and the upper elastic strip 130 can be selectively positioned one or the other, or both can be positioned simultaneously, as needed. However, it is clear that positioning both simultaneously achieves the aforementioned set of technical effects and is clearly the optimal embodiment.

[0044] Regarding the structure of the lower housing assembly 200, the structure of the lower housing assembly 200 is similar to the structure of the upper housing assembly 100, and as shown in Figures 4, 5 and 8, in one embodiment the lower housing assembly 200 includes a lower housing 210, a lower protective cover 220, and a lower elastic strip 230, the lower housing 210 is connected to the upper housing 110 of the upper housing assembly 100, for example in the figure, the lower housing 210 and the upper housing 110 are engaged with each other via an engagement structure with a buckle and an engagement groove, the lower protective cover 220 wraps the side of the lower housing 210 that faces away from the upper housing 110, the lower elastic strip 230 is provided between the lower protective cover 220 and the lower housing 210, and one side of the lower elastic strip 230 is attached to the lower housing 210 and the other side is attached to the lower protective cover 220.

[0045] Regarding the function and material of the lower housing 210, lower elastic strip 230, and lower protective cover 220, the functions of the lower housing 210 and upper housing 110, the lower elastic strip 230 and upper elastic strip 130, and the lower protective cover 220 and upper protective cover 120 are similar. Specifically, the lower housing 210 may be made of plastic to form the main frame of the lower housing assembly 200 and can also provide a certain clamping force; the material of the upper protective cover 120 may be leather to protect the lower housing 210 and serve to improve its decorative appearance; the material of the lower elastic strip 230 may be sponge to support the lower protective cover 220, thereby allowing the lower protective cover 220 to better wrap around and cover the lower housing 210; and since the lower housing assembly 200 comes into contact with the user's head, the lower elastic strip 230 provides a cushioning effect, making the contact between the lower housing assembly 200 and the head softer and improving the user's comfort when wearing the earphones.

[0046] Similarly, the lower elastic strip 230 may be similar to the upper elastic strip 130 and have a structure made of two layers of sponge laminated together. Specifically, as shown in Figures 4, 5, and 8, the lower elastic strip 230 includes a third elastic strip 231 and a fourth elastic strip 232 that are in close contact with each other, the length of the third elastic strip 231 being shorter than the length of the fourth elastic strip 232, the side of the third elastic strip 231 facing away from the fourth elastic strip 232 being attached to the lower housing 210, and the side of the fourth elastic strip 232 facing away from the third elastic strip 231 being attached to the lower protective cover 220. The surface of the lower housing 210 that is attached to the lower protective cover 220 and the side of the fourth elastic strip 232 facing away from the third elastic strip 231 are flush with each other in the arc direction of the lower housing 210, and preferably the hardness of the third elastic strip 231 is greater than the hardness of the fourth elastic strip 232.

[0047] Thus, the two-layer structure of the lower elastic strip 230 has similar technical effects to the two-layer structure of the upper elastic strip 130, namely, it saves radial dimensions of the lower housing assembly 200, makes it easier to enclose with the lower protective cover 220, and creates a structure in which the arc of the lower housing 210 and the arc of the fourth elastic strip 232 transition smoothly, making it easier to maintain the overall appearance of the lower housing assembly 200 and meeting the user's appearance requirements for the product.

[0048] Furthermore, as shown in Figures 12 and 13, as a further improvement to the lower housing assembly 200, mounting holes 211 are formed at both opposing ends of the lower housing 210, and guide sleeves 240 are fitted into each mounting hole 211, and the sliding member 40 is inserted through the guide sleeve 240 so that a part of the sliding member 40 is exposed to the outside of the headband structure 10.

[0049] Thus, compared to the conventional structure in which a guide ring with a large shape and dimensions is directly connected to the housing end of the headband structure 10, in the above embodiment, mounting holes 211 are formed at both ends of the lower housing and the sliding member 40 is connected to the earmuff. When adjusting the overall length of the earphone, only the length of the sliding member 40 exposed from the mounting holes 211 needs to be adjusted, thus simplifying the earphone production process and reducing the production cost of the earphone. Furthermore, since the sliding member 40 is located inside the headband structure 10 and only the sliding member 40 is exposed to the outside of the headband structure when using the earphone, the appearance of the earphone is simpler and more aesthetically pleasing.

[0050] The technical features of the embodiments described above can be combined in any way, and for the sake of brevity, not all possible combinations of the technical features in the embodiments described above have been described. However, as long as these combinations of technical features are inconsistent, they should be considered to fall within the scope described herein.

[0051] The embodiments described above illustrate only a few embodiments of the present application, and while these descriptions are specific and detailed, they should not be interpreted as limiting the scope of the utility model claims of the present application. Furthermore, a person skilled in the art may make various modifications and improvements as long as they do not deviate from the spirit of the present application, and both such modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the attached utility model claims. [Explanation of symbols]
