Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a headset. Background Technology

[0002] Headphones are audio devices worn on the head, covering or fitting the ears, for personal listening to music, making calls, or professional audio monitoring. Traditional headphones primarily employ either a one-piece or semi-modular design. A one-piece design uses a non-removable battery and employs adhesives or other methods to secure internal components, the earcups, and the headband. A semi-modular design allows for the replacement of some components, such as ear pads, but the core components remain fixed and non-removable, such as the battery, earcups, and headband. Semi-modular designs involve complex assembly processes, often relying on adhesives for fixation, leading to inconvenient maintenance and difficulties in repair.

[0003] In view of the above, a headset is proposed that is easy to disassemble and repair, and allows for the replacement and removal of the battery. Utility Model Content

[0004] The purpose of this invention is to overcome at least one deficiency in the prior art and provide an easily detachable headset while allowing for the replacement and removal of the battery.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A type of over-ear headphone includes: a headband and two earcups. Two open-type retaining rings are respectively provided at both ends of the headband. One or both earcups include a housing, a cover, and a battery cover. The housing has a receiving cavity and a battery cavity. A speaker unit is disposed in the receiving cavity, and a removable battery is installed in the battery cavity.

[0027] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0028] Please see Figures 1-7As shown, a type of over-ear headphone includes: a headband 100 and two earcups 200. Two open-type retaining rings 110 are respectively provided at both ends of the headband 100; the two open-type retaining rings 110 are detachably connected to the two earcups 200; one or both earcups 200 include a housing 210, a cover 220, and a battery cover 230. The housing 210 has a receiving cavity and a battery cavity. A speaker unit 240 is disposed in the receiving cavity, and a removable battery 250 is installed in the battery cavity; the cover 220 is detachably connected to the housing 210 by a screw connection, and the cover 220 is used to close the receiving cavity; the battery cover 230 is detachably snapped onto the housing 210, and the battery cover 230 is used to close the battery cavity.

[0029] It should be noted that two open-type retaining rings 110 are provided at both ends of the headband 100, and the open-type retaining rings 110 form a detachable connection with the earcups 200, so as to facilitate the disassembly, assembly and maintenance of the headband 100. At the same time, the earcups 200 are disassembled into structures such as the housing 210, the cover 220 and the battery cover 230, and the cover 220 and the battery cover 230 are detachably connected to the housing 210, so as to facilitate the opening of the cavity containing the speaker unit 240 and the battery cavity containing the battery, thereby facilitating the assembly and disassembly of the corresponding components, as well as the maintenance of specific components and the removal and replacement of the battery. Thus, by using a modular design, the headphones are broken down into multiple modules, allowing not only the earcups 200 and headband to be detached, but also the earcup shell 210 to be detached. This also enables independent battery removal and replacement, improving the usability of the headphones. In this embodiment, the removable battery 250 is a removable lithium-ion battery, which not only allows for charging but also for battery replacement, enhancing the user experience and reducing battery anxiety. When the battery ages, only the battery module needs to be replaced, preventing the entire device from becoming unusable due to battery deterioration and extending the headphones' lifespan. (See reference...) Figure 1 , Figure 2 and Figure 3 As shown, the earcup 200 also includes an ear pad 260. An elastic limiting part 261 is provided around the mounting side of the ear pad 260. Specifically, one end of the elastic limiting part 261 is connected to the edge of the ear pad 260, and the other end of the elastic limiting part 261 extends towards the center of the ear pad 260. Correspondingly, the shell 210 and the cover 220 are not completely fitted after assembly, that is, there is an installation gap A between the shell 210 and the cover 220. When installing the ear pad 260, the elastic limiting part 261 is opened and squeezed from the installation gap A into the receiving cavity, so that the ear pad 260 wraps around the cover 220, thereby forming the installation of the ear pad 260, and also facilitating the removal and replacement of the ear pad 260. The elastic limiting part 261 can be an elastic band.

[0030] It should also be noted that the inclusion of a housing 210, a cover 220, and a battery cover 230 in one or both earcups 200 refers to two possible configurations. The first configuration involves only one earcup 200 including the housing 210, cover 220, and battery cover 230, while the other earcup 200 only includes the housing 210 and cover 220. In other words, only one earcup 200 contains a removable battery 250, and the two earcups 200 can be connected via a corresponding electrical connection structure. The second configuration involves both earcups 200 including the housing 210, cover 220, and battery cover 230, meaning both earcups 200 contain a removable battery 250. Preferably, both earcups 200 include the housing 210, cover 220, and battery cover 230.

[0031] It should also be noted that the following can be consulted: Figure 5 and Figure 6 As shown, the cover 220 and the housing 210 are connected by screws. Specifically, the housing 210 has a connecting post 211 with a threaded hole, and the cover 220 has a mounting post 221 with a mounting hole. When the cover 220 and the housing 210 are assembled, the mounting hole on the mounting post 221 is aligned with the threaded hole on the connecting post 211. In this way, screws and other screws can pass through the threaded hole and the mounting hole respectively to form a connection, thereby connecting the cover 220 and the housing 210.

[0032] Furthermore, to facilitate installation and ensure the accuracy and efficiency of the installation position of the cover 220, please refer to... Figure 5 As shown, a positioning post 212 is provided on the housing 210, and a positioning hole 222 is opened on the cover 220. The positioning hole 222 is notched. When the positioning post 212 is inserted into the positioning hole 222, the positioning hole 222 is expanded and the positioning post 212 is pressed. Then the screw-on parts can be assembled, thereby improving the accuracy of the assembly position.

[0033] Specifically, the open-type retaining ring 110 has a limiting protrusion 111 on the side facing the earcup 200, and a retaining hole 213 is provided on the housing 210. When the open-type retaining ring 110 is connected to the earcup 200, the limiting protrusion 111 passes through the retaining hole 213. In this way, the earcup 200 and the headband can be fixed in place, avoiding the risk of the headband falling off. Furthermore, the open-type retaining ring 110 has a semi-circular ring structure, that is, the open-type retaining ring 110 partially encircles the housing 210, and there are two limiting protrusions 111, which are respectively provided at both ends of the open-type retaining ring 110. There are two retaining holes 213, and the limiting protrusions 111 pass through the retaining holes 213 respectively. The semi-circular ring structure can provide a uniform clamping force, and together with the two limiting protrusions 111, it can provide a stable and reliable mechanical connection, ensuring the stability between the earcup 200 and the headband. The open-type retaining ring 110 is made of plastic and has a certain degree of elasticity. It can apply a pulling force to both ends of the open-type retaining ring 110, so that the limiting protrusions 111 at both ends move away from the earcups 200, thereby separating the limiting protrusions 111 from the retaining holes 213 and thus disassembling the headband.

[0034] Furthermore, to further ensure the secure installation of the headband 100, please refer to [link / reference needed]. Figure 4 , Figure 5 and Figure 7 As shown, a limiting groove 111a is also provided on the limiting protrusion 111, and a limiting plate 223 is provided on the side of the cover 220 facing the limiting protrusion 111. When the cover 220 is connected to the housing 210, the limiting plate 223 is located in the limiting groove 111a. In this way, by providing the limiting plate 223 on the cover 220, a locking mechanism is provided for the installation of the headphone headband 100, further ensuring the locking and fixing of the headphone headband 100 and preventing the risk of the headphone headband 100 and the earcups 200 accidentally falling off during use. That is, during assembly, the headphone headband 100 and the housing 210 are assembled first, and then the cover 220 is installed, so that the limiting plate 223 on the cover 220 can be engaged with the limiting groove 111a on the limiting protrusion 111 in the headphone headband 100, thereby achieving limiting locking and ensuring the stability of the connection. In this embodiment, the limiting plate 223 is provided with reinforcing ribs, which can further improve the structural strength of the limiting plate 223, thereby further improving the stability of the connection and reducing the risk of detachment.

[0035] Please see Figure 5 and Figure 6 As shown, in one embodiment, a limiting groove is provided inside the battery cavity, and a clearance groove 214 is provided on one side of the limiting groove, and the battery is installed in the limiting groove. In this way, the battery installation position can be ensured accurately, and the purpose of providing the clearance groove 214 is to facilitate the user to remove the battery from the limiting groove.

[0036] Please see Figure 5 and Figure 7 As shown, in one embodiment, a locking member 240 is installed on the housing 210, and a limiting hook 231 is provided on the side of the battery cover 230 facing the locking member 240. The locking member 240 and the limiting hook 231 are connected to form a detachable connection between the battery cover 230 and the housing 210. This allows for quick locking and releasing of the battery cover 230, providing a reliable fixing effect. Specifically, the locking member 240 includes a return spring 241 and a locking block 242. One end of the return spring 241 is connected to the housing 210, and the other end is connected to the locking block 242. The limiting hook 231 on the battery cover 230 is connected to the locking block 242 to form a detachable connection between the battery cover 230 and the housing 210. It should be noted that the locking block 242 is provided with a latching part 242a. When the battery cover 230 is connected to the housing 210, the latching part 242a on the locking block 242 and the limiting hook 231 on the battery cover 230 abut against each other along the direction of deformation of the return spring 241. When it is necessary to remove the battery cover 230, the locking block 242 can be pushed, and the return spring 241 can be extended at the same time, so that the locking block 242 moves until the latching part 242a on the locking block 242 and the limiting hook 231 on the battery cover 230 disengage from each other. In this way, the connection between the battery cover 230 and the housing 210 can be released, thereby realizing the removal of the battery cover 230. The pushing part 242b of the locking block 242 extends to the outside of the housing 210, so that the user can move the locking block 242 by pushing the pushing part 242b of the locking block 242.

[0037] Furthermore, the locking member 240 also includes a limiting block 243, which has a limiting cavity. The limiting block 243 is installed inside the housing 210, and the locking block 242 is located inside the limiting cavity. A support seat 210a is formed on the housing 210, and a clearance hole is provided on the support seat 210a. A clearance hole is also provided on the housing 210 to connect to the outside, allowing the pushing part 242b on the locking block 242 to extend to the outside through the clearance hole. The limiting block 243 has an L-shape, with one end connected to the side wall of the housing 210 and the other end abutting against the support seat 210a. The limiting block 243 and the support seat 210a form a double-opening limiting cavity, and the locking block 242 is located in the limiting cavity and moves along the two openings of the limiting cavity.

[0038] Please see Figure 1 , Figure 3 and Figure 4As shown, in one embodiment, the headphone headband 100 includes a connecting beam 120 and an elastic adjustment beam 130. Two open-type retaining rings 110 are respectively disposed at both ends of the connecting beam 120, and both ends of the elastic adjustment beam 130 are respectively connected to both ends of the connecting beam 120. The connecting beam 120 provides connection support for the two earcups 200; while the elastic adjustment beam 130 provides adaptive adjustment, allowing the headphones to adapt to different user head sizes. For example, the elastic adjustment beam 130 includes a connecting portion and elastic portions connected to both ends of the connecting portion. The elastic portions at both ends are respectively connected to both ends of the connecting beam 120. When pressure is applied to the elastic adjustment beam 130, the elastic portions are stretched to match different head sizes; for example, the elastic portions are elastic bands.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
