In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] The present disclosure provides an earphone device, the earphone device comprising: a front module, when the user wears the earphone device, the front module faces the ear of the user, wherein the front module comprises a driver assembly; a rear module, when the user wears the earphone device, the rear module faces away from the ear of the user, wherein the rear module is detachably connected to the front module, and wherein the rear module comprises a main circuit board; and a battery module, the battery module is detachably arranged in the earphone device. The battery module comprises a hard circuit board, by means of which the electrical connection between the battery module and the front module and the electrical connection between the battery module and the rear module can be realized respectively.

[0042] In the prior art, the battery used in the headphone device is either not replaceable, or can only be replaced by professionals using professional tools, or the battery is connected to the driver and main circuit board in different modules through complex conductive lines, which is easy to make mistakes and lose parts when replacing the battery. Compared with the prior art, the battery module according to the present disclosure realizes an overall modular structure, and the battery module is electrically connected to the front module and the rear module by means of a hard circuit board included in the battery module. This not only realizes a more compact and simple structural design, but also eliminates the complex and messy wire connection method, allowing ordinary consumers to conveniently perform battery replacement operations.

[0043] In some embodiments of the present disclosure, the battery module further includes a battery housing, a battery housed in the battery housing, wherein the rigid circuit board is electrically connected to the battery. The rear module includes a housing for the battery module on a side facing the front module, wherein the battery module is detachably arranged in the housing so that the rigid circuit board faces the front module, and wherein the main circuit board is fixedly mounted at the bottom of the housing. Thus, the battery module is disposed as a whole between the front module and the rear module, and the battery module together with its rigid circuit board is exposed to the outside after the front and rear modules are disassembled. Thus, the electrical connection between the modules, especially the electrical connection between the rear module and the battery module, can be performed under visual observation of the user, which simplifies the battery replacement process while also enabling visual inspection of the electrical connection between the modules.

[0044] In some embodiments of the present disclosure, the rigid circuit board includes a first connector for electrically connecting to the front module and a second connector for electrically connecting to the rear module. The front module includes a first mating connector that cooperates with the first connector. Preferably, the first connector and the first mating connector are constructed as spring pin contacts and spring pins that cooperate with each other. To this end, the first connector on the rigid circuit board can be designed as a spring pin contact, and the first mating connector on the front module can be designed as a spring pin. Of course, the opposite design can also be considered, that is, the first connector on the rigid circuit board can be designed as a spring pin, and the first mating connector on the front module can be designed as a spring pin contact.

[0045] In some embodiments of the present disclosure, the rear module includes a second mating connector that cooperates with the second connector. The second connector and the second mating connector are plugged into each other. Preferably, the second mating connector is connected to the main circuit board via a flexible circuit board, and the flexible circuit board is constructed as a longitudinally extending strip. Thus, one end of the flexible circuit board serving as the second mating connector is fixedly connected to the main circuit board of the rear module, and the other end is plugged into the second connector in a simple manner with the aid of its connector. The flexible circuit board is bendably constructed, and this flexible design allows the second connector constructed at its free end to be connected to the outward-facing side of the rigid circuit board. This design further ensures the reliable implementation of the electrical connection between the rear module and the battery module.

[0046] In some embodiments of the present disclosure, the rigid circuit board is arranged in the battery housing so as to at least partially cover the battery, wherein the battery housing includes a retainer, and the rigid circuit board and the battery are held together in the battery housing by the retainer. Preferably, the retainer is configured as a plurality of springs protruding radially inward from the opening edge of the battery housing, and the free ends of the springs are used to abut against the top side of the rigid circuit board, thereby pressing the rigid circuit board toward the battery. This ensures the stability of the integrated structure of the battery module.

[0047] In some embodiments of the present disclosure, an auxiliary mounting member is arranged between the battery and the rigid circuit board, and the auxiliary mounting member extends at least partially along the edge of the rigid circuit board on the bottom side of the rigid circuit board. Preferably, the auxiliary mounting member is configured as an annular member, and the annular member has at least one radial flange protruding radially outward, wherein the battery housing includes a housing notch extending downward from the edge of the opening, and the housing notch and the radial flange are mutually adapted, thereby allowing the radial flange to protrude outward from the battery housing in the assembled state of the battery module. The annular member only abuts against the bottom side of the rigid circuit board at the edge, and does not interfere with the electrical connection between the rigid circuit board and the battery. The radial flange protrudes outward from the housing notch, and the consumer can apply force to the radial flange, and by pulling the auxiliary mounting member upward, the rigid circuit board arranged above the auxiliary mounting member is pushed out of the battery housing, thereby allowing the battery below it to be easily replaced.

[0048] Figures 1 to 3 The headphone device 10 according to one or more embodiments of the present disclosure is schematically shown. The headphone device 10 includes a front module 12, a rear module 14 and a battery module 16.

[0049] like Figure 2 As shown, the front module 12 includes a front module housing 120, and the space enclosed by the front module housing 120 is constructed to accommodate and surround the driver assembly 122 of the headphone device 10 and other electroacoustic devices not further shown, such as a speaker assembly. When the user wears the headphone device 10, the front module 12 faces the ear of the user. The front module housing 120 includes an outer contour extending in a quasi-conical or teardrop shape, so that it can at least partially fit the ear of the user in an ergonomic manner. Figures 1 to 3 In an optional embodiment shown, the earphone device 10 includes an earplug 126 at its end facing the ear of the user. Of course, in an embodiment not shown, an earphone device without an earplug can also be considered.

[0050] The rear module 14 includes a rear module housing 140, and the space surrounded by the rear module housing 140 is configured to accommodate and surround the main circuit board 142 of the earphone device 10. When the user wears the earphone device 10, the rear module 14 faces away from the user's ear. The rear module housing 140 includes a head section and a handle section, which extend in transition to each other, and the head section gradually expands from the handle section to adapt to the outer contour shape of the front module housing 140.

[0051] The rear module 14 includes a receiving portion 148 on the side facing the front module 12, and the battery module 16 is detachably arranged in the receiving portion 148. Figure 3In the illustrated embodiment, the receiving groove 110 has a substantially circular cross-section so as to receive a battery module 16 having a corresponding geometry.

[0052] like Figure 4 and Figure 5 As shown, the battery module 16 includes a battery housing 160, batteries 162, a hard circuit board 166, and a ring member 164 as an optional auxiliary mounting member.

[0053] The battery housing 160 is cylindrical in shape as a whole, and accordingly, the battery 162 is also constructed as a substantially flat cylinder. The hard circuit board 166 is disc-shaped, and its diameter is substantially the same as the diameter of the battery 162, so as to be able to at least partially cover the battery 162. The battery 162 and the hard circuit board 166 are both accommodated in the battery housing 160. In order to maintain the structural stability of the battery module 16, the battery housing 160 is provided with a retainer. In this embodiment, the retainer is configured as a plurality of springs 1602 extending radially inward along the opening edge of the battery housing 160. In this embodiment, four springs 1602 are arranged substantially uniformly distributed along the circumference, but alternatively, any number of springs, such as 2, 3, 6, or 8 springs, can be provided. In the assembled state of the battery module 16, the top side 166a of the hard circuit board 166 faces the outside, and the bottom side 166b of the hard circuit board 166 faces the battery 162 below it. The spring piece 1602 abuts against the top side 166 a of the rigid circuit board 166 with its free end and presses it toward the battery 162 , thereby firmly and reliably holding the rigid circuit board 166 and the battery 162 in the battery housing 160 .

[0054] During the battery replacement process, it is necessary to remove the old battery from the battery housing and then install the new battery. To this end, the hard circuit board 166 covering the battery 162 must be removed from the battery housing 160 first. In order to facilitate the removal of the hard circuit board 166, an auxiliary mounting member is provided between the hard circuit board 166 and the battery 162. The auxiliary mounting member can be constructed as an annular member 164, and the annular member 164 has at least one radial flange 1642 protruding radially outward. Correspondingly, the battery housing 1604 includes a housing recess 1604 extending downward from the edge of the opening, and the housing recess 1604 is adapted to the radial flange 1642, thereby allowing the radial flange 1604 to protrude outward from the battery housing 160 in the assembled state of the battery module 16. Consumers can use their fingers to push the radial flange 1642, so that the annular member 164 can be tilted upward as a whole, thereby driving the hard circuit board 166 arranged above the annular member 164 to be pushed out of the battery housing 160, thereby allowing the battery 162 thereunder to be easily replaced.

[0055] To electrically connect to the front module 12 and the rear module 14, the rigid circuit board 166 includes a first connector 168 and a second connector 170 on its top side 166a. Accordingly, the front module 12 and the rear module 14 include a first mating connector 124 and a second mating connector 146 respectively adapted thereto.

[0056] In a preferred embodiment, the first connector 168 is configured as a spring pin contact. The number of spring pin contacts can be appropriately designed according to design requirements, for example, 8 spring pin contacts 168. The front module 12 includes a corresponding number of spring pins as the matching first connector 124. The spring pins can be elastically preloaded to contact the spring pin contacts.

[0057] The second connector 170 and the second mating connector 146 can be plugged into each other. The second mating connector 170 has a plug-in connector arranged on the top side 166a of the rigid circuit board 166, and the second mating connector 146 is configured as a mating plug-in connector. The rear module 14 includes a flexible circuit board 144, which is configured as a longitudinally extending strip. One end of the flexible circuit board 144 is fixedly connected to the main circuit board 142 installed at the bottom of the accommodating portion 148, and the other end is connected to the second mating connector 146. The flexible circuit board 166 extends from the bottom of the accommodating portion 148 along the side wall to the top. Through the bending of the flexible circuit board 166, the second mating connector 146 is plugged into the second connector 170 from the top side 166a of the rigid circuit board 166.

[0058] To realize the assembly of the earphone device 10, the front module housing 120 and the rear module housing 140 are locked and connected with each other. Figure 6 and Figure 7 As shown, the rear module housing 140 has a first latching flange 1402 protruding toward the front module housing 120 at its head section, and the front module housing 120 correspondingly has a second latching flange 1202 protruding toward the rear module housing 140. The mutual latching of the first latching flange 1402 and the second latching flange 1202 realizes a detachable connection between the front module housing 120 and the rear module housing 140. In particular, Figure 7 As shown, the first locking flange 1402 is retracted radially inward relative to the outer periphery of the rear module housing 140, thereby forming a step portion between the outer periphery of the rear module housing 140 and the first locking flange 1402. The second locking flange 1202 has a groove formed on its inner side for accommodating the expansion portion of the free end of the first locking flange 1402 in a shape-fitting manner. In addition, at least one recess 150 is provided on the step portion of the rear module 14. In particular, Figure 1As shown, the recess 150 at least partially interrupts the step portion in the circumferential direction, thereby forming at least one notch on the circumferential joint portion of the front module housing 120 and the rear module housing 140. The recess 150 facilitates the user to apply external force between the front module housing 120 and the rear module housing 140, thereby more easily separating the two. As an alternative or supplement, the recess 150 can also be set on the front module 12.

[0059] like Figures 6 to 9 As shown, in the assembled state of the headphone device 10, the spring pin as the first mating connector 124 elastically pre-tightens in contact with the spring pin contact as the first connector 168, thereby realizing the electrical connection between the driver assembly 122 and the hard circuit board 166; the second mating connector 146 is plugged into the second connector 170, thereby realizing the electrical connection between the main circuit board 142 and the hard circuit board 166.

[0060] When the battery of the headset device 10 needs to be replaced, first, the front module housing 120 is separated from the rear module housing 140, thereby exposing the battery module 16 accommodated in the accommodating portion 148, and the top side 166a of the hard circuit board 166 is exposed. Subsequently, the plugging between the second connector 170 on the hard circuit board 166 and the second mating connector 146 of the rear module 14 is released, thereby allowing the entire battery module 16 to be removed from the accommodating portion 148. As described above, the hard circuit board 166 is removed from the battery housing 160 with the aid of the auxiliary mounting member, and the old battery 162 is replaced with a new battery. Subsequently, the auxiliary mounting member and the hard circuit board 166 are reinstalled in the battery housing 160 in sequence, thereby completing the reassembly of the battery module 16. The assembled battery module 16 is rearranged in the accommodating portion 148, and after the second connector 170 is reconnected with the second mating connector 146, the front module housing 120 and the rear module housing 140 are re-engaged. Thus, the battery replacement is completed.
