Description

Technical Field

[0001] The utility model relates to a head-mounted earphone, and particularly to a headband structure of the head-mounted earphone. Background Art

[0002] With the rapid development of science and technology, various electronic products have developed more rapidly. Among them, earphones can be used as a medium for sound transmission between electronic devices and human ears to transmit sound information to human ears.

[0003] In the case of a head-mounted earphone, the headband, as the main support structure, needs to take into account both structural strength and comfort. Therefore, it is mostly made of a metal bracket with foam or soft pads. However, for the metal bracket, although it meets the required structural strength, due to its clamping structure, it has a high hardness and no elasticity. Therefore, the mating component combined with it can only adopt a chute (or a similar sliding structure) design. At the same time, the clamping structure made of metal also has problems such as difficult assembly or excessive rigidity, and thus the external dimensions of the headband cannot be further reduced. Summary of the Utility Model

[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art, and provides a headband structure of a head-mounted earphone, which provides assembly convenience and has a thin and light overall appearance.

[0005] The headband structure of the head-mounted earphone of the present invention includes a first headband, a second headband and a plurality of hooks. The hooks are arranged on one of the first headband and the second headband, and the other of the first headband and the second headband has a plurality of buckle holes. The first headband and the second headband are assembled together by the hooks being correspondingly inserted into and buckled in the buckle holes.

[0006] In one embodiment of the present invention, the above-mentioned hooks are made of plastic material. Among the first headband and the second headband, the one provided with hooks is made of metal material, and the one provided with buckle holes is made of plastic material.

[0007] In one embodiment of the present invention, the above-mentioned headband structure further includes at least one base, which is arranged on one of the first headband and the second headband. The base has at least one extension part, and the hook is erected on the extension part.

[0008] In one embodiment of the present invention, the above-mentioned hook is formed on the extension part by insert injection molding.

[0009] In one embodiment of the present invention, the above-mentioned base is made of metal material and is welded to one of the first headband and the second headband.

[0010] In one embodiment of the present invention, the above-mentioned base is in an I shape and has four said extension parts.

[0011] In one embodiment of the present invention, the above-mentioned base includes a main body that is in surface contact with the first headband or the second headband, and ribs that are bent and extended from the main body and stand on the first headband or the second headband. The hooks are engaged and wrapped around the ribs, and the main body has the extension portion.

[0012] In one embodiment of the present invention, the above-mentioned hook and the first headband or the second headband are of an integral structure.

[0013] In one embodiment of the present invention, the above-mentioned hook is formed on the surface of the first headband or the surface of the second headband by insert injection molding.

[0014] In one embodiment of the present invention, the above-mentioned hooks are combined in pairs and stand on the first headband or the second headband. Among them, the hooks are arranged along the opposite inner edges of the first headband or the second headband. The hook parts of the hooks located on different inner edges face away from each other, and the insertion direction is the same as the direction in which each hook protrudes from the first headband or the second headband.

[0015] Based on the above, the headband structure of the headset is provided with a plurality of hooks on one of the first headband and the second headband, and a plurality of independent buckle holes are formed on the other of the first headband and the second headband. Therefore, the first headband and the second headband can be assembled together by correspondingly inserting and buckling the hooks into the buckle holes. In other words, because the hooks and the buckle holes are in a corresponding state, it is obvious that the first headband and the second headband are combined in a butt-joint rather than a sliding connection manner. This simplifies the assembly process of the headband structure.

[0016] Generally speaking, since the headband structure needs to conform to the user's head and has a generally arc-shaped or elliptical arc-shaped outer contour, for the assembly process, it is actually not conducive to assembling the first headband (or the second headband) by sliding along one end of the second headband (or the first headband) to the other end. On the contrary, due to the above-mentioned configuration of the hooks and the buckle holes in this case, the first headband and the second headband are in a butt-joint and fitting mode, which provides quite a lot of convenience. At the same time, because the sliding assembly mode is avoided, the hooks and the buckle holes can also omit the structures required for sliding in the prior art with respect to the first and second headbands, and effectively narrow the first headband and the second headband, so as to provide a thinner and lighter headband structure.

[0030] Embodiment

[0031] Figure 1 is a schematic diagram of a headset according to an embodiment of the present new creation. Please refer to Figure 1 , in this embodiment, the headset 100 includes a headband structure 110 and two earcups 120, 130 provided at opposite ends of the headband. At the same time, a speaker unit (not shown) is further provided inside each of the earcups 120, 130. Here, the earcup 120, the speaker unit therein, and the related connection lines or electronic components are already features known in existing headsets, so they will not be described in detail here.

[0032] Figures 2 to 4 is Figure 1 an exploded view of different parts of the headset. Please refer to Figures 2 to 4 In this embodiment, the headband structure 110 further includes a first headband 111, a second headband 112, a buffer member 115, and a plurality of hooks 113. The hooks 113 are provided on one of the first headband 111 and the second headband 112, and the other of the first headband 111 and the second headband 112 has a plurality of buckle holes independent of each other. In this embodiment, taking the hooks 113 being provided on the first headband 111 and the second headband 112 having a plurality of buckle holes 112a as an example, vice versa and will not be described in detail here. In this way, by correspondingly inserting and fastening the hooks 113 into the buckle holes 112a, the first headband 111 and the second headband 112 can be assembled together. Then, the buffer member 115 (such as foam or soft pad) is combined with the second headband 112 to complete the production of the headband structure 110.

[0033] In this embodiment, the hooks 113 are arranged along the opposite inner edges 111b of the first headband 111 and stand on the inner surface S1, where the hook portions of the hooks 113 located on different inner edges 111b face away from each other, and the direction in which the hooks 113 correspond to the insertion of the buckle holes 112a is the same as the direction in which each hook 113 protrudes from the inner surface S1. Here, the hooks 113 are made of plastic, and among the first headband 111 and the second headband 112, the one provided with the hooks 113 is made of metal (here it is the first headband 111), and the one provided with the buckle holes 112a is made of plastic (here it is the second headband 112). Accordingly, for the first headband 111, in addition to maintaining the rigid structure of the metal material, it can further have considerable flexibility and elasticity due to the plastic material of the hooks 113, and thus can be smoothly inserted and buckled into the buckle holes 112a made of the same plastic material.

[0034] On the other hand, as Figure 3A , Figure 3B and Figure 3C shown, where Figure 3B and Figure 3C are Figure 3A magnified schematic views of the partial areas A1 and A2. The first headband 111 also has a plurality of screws 111a located at opposite ends, and the second headband 112 also has a plurality of screw holes 112b located at opposite ends, so that when the first headband 111 and the second headband 112 are fitted and docked, the screws 111a can be inserted and locked into the screw holes 112b to achieve the required positioning and screwing fixation effect and clamp the harpoon 121 extending from the earcup 120 in the middle.

[0035] Figure 5A is an exploded view of the hook. Figure 5B is a partial cross-sectional view of the hook. Please also refer to Figure 4 , Figure 5A and Figure 5B , in the headband structure 110 of this embodiment, in order to enable the hooks 113 to be smoothly combined with the first headband 111, the hooks 113 are combined in pairs and stand on the inner surface S1 of the first headband 111, and the headband structure 110 also includes a plurality of bases 114, which are also provided on the inner surface S1 of the first headband 111, and two pairs of hooks 113 are placed on the bases 114. Here, the base 114 has at least one extension portion 114a, and the hook 113 stands on the extension portion 114a.

[0036] In detail, the base 114 includes a main body composed of a connecting portion 114b and an extending portion 114a. Here, an I-shaped main body is taken as an example, which has four extending portions 114a, wherein the main body (connecting portion 114b and extending portion 114a) is substantially in contact with the inner surface S1 of the first headband 111. Furthermore, the base 114 is made of metal, so after the main body (connecting portion 114b and extending portion 114a) is formed by stamping, a plurality of ribs 114c can be further bent and extended from the main body and stand on the inner surface S1. Here, the ribs 114c extend from the extending portions 114a of the main body respectively. The hook 113 is molded and combined by embedded injection molding and is covered on the rib 114c. In addition, as Figure 5A and Figure 5B As shown, the rib 113b is used to increase the bonding between the hook 113 and the base 114 during the embedded injection process, and also ensures that the hook 113 has sufficient structural strength to withstand the buckling process between the buckle hole 112a. In addition, the two adjacent hooks 113 located on the same inner edge 111b are actually formed together with two hook portions 113a and a connecting portion 113b connected between the two hook portions 113a, which also increases the bonding strength and stability between the base 114 and the hook 113.

[0037] like Figure 4 and Figure 5A As shown, during the manufacturing process, the hooks 113 are first combined with the base 114 in pairs by insert injection molding. Since the base 114 is made of metal, the combination is subsequently completed by welding the base 114 to the inner surface S1 of the first headband 111 along the inner edge 111b.

[0038] Figure 6 This is a schematic diagram of some components of a headset according to another embodiment of the present invention. Figure 6 , which is different from the previous embodiment, in the headband structure of this embodiment, the hook 213 and the first headband 211 are an integrated structure. Here, the hook 213 is placed on the inner surface S2 of the first headband 211 in pairs through an embedded injection process, and is also arranged on the two opposite inner edges 211b of the first headband 211 to correspond one-to-one with the buttonholes of the second headband (as shown in the previous embodiment, which is omitted here). In this embodiment, the hook 213 is composed of two pairs of hook portions 213a and a connecting portion 213b connecting them, wherein the connecting portion 213b also has a portion extending toward the inner side of the first headband 211 in terms of structure (the extension direction is as shown in FIG. 1 ). Figure 6 ), which is opposite to the extension direction of the hook portion 213a (as shown by the dashed arrow on the left side of the figure). Figure 6as shown by the right dashed arrow in the figure), so as to increase the contact area between the hook 213 and the inner surface S2, thereby increasing the bonding strength of the structure. In addition, the same structures as those in the foregoing embodiments are denoted by the same reference numerals and will not be described in detail again.

[0039] In summary, in the above embodiments of the present invention, the headband structure of the head-mounted earphone is provided with a plurality of hooks on one of the first headband and the second headband, and a plurality of independent buckle holes are formed on the other of the first headband and the second headband. Therefore, the first headband and the second headband can be assembled together by correspondingly inserting and fastening the hooks into the buckle holes. In other words, precisely because the hooks and the buckle holes are in a corresponding state, it is obvious that the first headband and the second headband are combined in a butt-joint rather than a sliding manner. This simplifies the assembly process of the headband structure.

[0040] In one embodiment, the hook includes a base made of a metal part, which facilitates the plastic hook to be formed on the base by insert injection molding, and then the base and the hook thereon are welded to the inner surface of the first headband. In another embodiment, the plastic hook is directly formed on the inner surface of the first headband by insert injection molding.

[0041] Generally speaking, since the headband structure needs to conform to the user's head and is generally in an arc or elliptical arc contour, for the assembly process, it is actually not conducive to assembling the first headband (or the second headband) by sliding from one end of the second headband (or the first headband) to the other end. On the contrary, due to the above configuration of the hooks and the buckle holes in this case, regardless of which embodiment is shown, the first headband and the second headband are in a butt-joint and fitting mode, which provides quite a lot of convenience. At the same time, because the sliding assembly mode is avoided, the hooks and the buckle holes can also omit the structures required for sliding in the prior art with respect to the first and second headbands, effectively narrowing the first headband and the second headband, thereby providing a thinner and lighter headband structure.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention. Those skilled in the art can also make other changes within the spirit of the present invention for use in the design of the present invention, as long as they do not deviate from the technical effects of the present invention. These changes made according to the spirit of the present invention should all be included within the scope of protection required by the present invention.
