[0044] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only for explaining the present application and not for limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0045] The terms "comprising" and "having" and any variations thereof in the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0046] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0047] As Figures 1 to 4 shown, corresponding to a battery compartment of a preferred embodiment of the present utility model, it includes a housing assembly 1, a battery 2, and a lighting module 4.

[0048] The housing assembly 1 includes a panel 10, and at least part of the panel 10 is made of a light-transmitting material, such as transparent plastic or glass and other materials. The housing assembly 1 can be formed by connecting multiple housings. As Figure 2 shown, the housing assembly 1 includes a first housing 11 and a second housing 12 that are connected to each other. Optionally, the panel 10 is provided on the first housing 11, and the battery 2 is fixedly connected to the second housing 12.

[0049] The battery 2 is disposed inside the housing assembly 1, and the housing assembly 1 can be made of materials such as plastic or plastic with glass fiber, etc.

[0050] The light-emitting module 4 is located between the battery 2 and the panel 10. The light-emitting module 4 includes a light source 40 and a light guide plate 41 for guiding light. The light guide plate 41 is correspondingly arranged with the light-transmitting part of the panel 10 to ensure that the light conducted by the light guide plate 41 can be transmitted to the outside of the battery compartment. The light guide plate 41 includes a top surface 412 facing the panel 10, a first bottom surface 413 facing the battery 2, and an outer peripheral surface 414 located between the top surface 412 and the first bottom surface 413. The light source 40 is correspondingly arranged with the outer peripheral surface 414 of the light guide plate 41 and is electrically connected to the battery 2, and the battery 2 provides energy for the light source 40. Optionally, the light source 40 is arranged facing the light guide plate 41, ensuring that most of the light of the light source 40 can be transmitted to the light guide plate 41, thereby improving the transmission efficiency of the light source 40.

[0051] By arranging the light source 40 in the battery compartment, the light is transmitted to the outside of the battery compartment through the light guide plate 41 and the light-transmitting part of the panel 10, realizing the lighting of the battery compartment. The light-emitting module 4 is located between the battery 2 and the panel 10, and the light source 40 is correspondingly arranged with the outer peripheral surface 414 of the light guide plate 41, rather than being stacked in the thickness direction. Therefore, the light-emitting module 4 occupies less space inside the battery compartment, which is beneficial to making the entire battery compartment small in volume and compact in structure, beneficial to reducing the weight of the product, improving the wearing experience and reducing the load feeling of the entire earphone. At the same time, the light guide plate 41 has a large area, thereby increasing the light-emitting area of the battery compartment, and the light emitted by the battery compartment is more uniform under the action of the light guide plate 41.

[0052] As Figures 2 to 6 As shown, the housing assembly 1 is provided with a receiving hole 110, the panel 10 seals the outer end of the receiving hole 110, and both the light guide plate 41 and the light source 40 are arranged in the receiving hole 110, reducing the space occupied by the light-emitting module 4 inside the battery compartment. For a battery compartment of the same volume, a larger-volume battery 2 can be accommodated, thereby improving the energy storage efficiency of the battery compartment. In addition, the light guide plate 41 and the light source 40 are arranged in the receiving hole 110, and the light guide plate 41 is correspondingly arranged with the light-transmitting part of the panel 10, effectively avoiding the shielding of light by other parts of the housing assembly 1 and improving the light-emitting brightness of the battery compartment.

[0053] The light-emitting module 4 can improve the aesthetics of the earphone. In addition, in some embodiments, the working state of the earphone can be identified through the light-emitting color and / or blinking frequency of the light-emitting module 4, such as identifying the on / off state, charging state or whether the battery is fully charged, etc.

[0054] Optionally, when the earphone is worn, the panel 10 is located on the side of the earphone facing away from the head, and it is not close to the human body to prevent being blocked by the human body, and the light emitted by it is more convenient to be observed by external personnel.

[0055] As Figures 3 to 7As shown, a first mounting groove 111 communicating with the receiving hole 110 is provided on the inner surface of the housing assembly 1. The battery compartment includes a flexible circuit board 3. The flexible circuit board 3 includes a first board body 30 provided with a light source 40 and a light guide plate 41, and a second board body 31 connected to the first board body 30. The second board body 31 is electrically connected to the battery 2, and the first board body 30 is disposed in the first mounting groove 111.

[0056] The flexible circuit board 3 is electrically connected to the light source 40 and the battery 2 respectively, and the battery 2 provides electrical energy for the light emission of the power source 40; the flexible circuit board 3 is located between the battery 2 and the panel 10. Compared with a general circuit board, the flexible circuit board 3 is thinner, and the first board body 30 of the flexible circuit board 3 is disposed in the first mounting groove 111, thereby effectively reducing the occupation of the battery compartment space by the flexible circuit board 3. The battery 2 can thus be made larger, improving the energy storage efficiency of the battery 2.

[0057] Furthermore, the first board body 30 is attached to the outer surface of the battery 2. For example, it can be fixedly connected by gluing, reducing the gap between the outer surface of the first board body 30 and the battery 2, thereby reducing the occupation of the internal space of the battery compartment by the flexible circuit board 3. In addition, it is convenient for assembly and improves the assembly efficiency. For example, the flexible circuit board 3 can be first connected to the battery 2, and then the battery 2 can be installed in the second housing 12, and then the first housing 11 can be installed.

[0058] As Figure 2 、 Figure 5 、 Figure 6 and Figure 8 As shown, a second mounting groove 112 communicating with the receiving hole 110 is provided on the outer surface of the housing assembly 1, and the panel 10 is disposed in the second mounting groove 112. The second mounting groove 112 can play a limiting role and facilitate the installation of the panel 10 during the assembly of the battery compartment; further, Figure 2 In the embodiment shown, the contour of the second mounting groove 112 is adapted to the outer contour of the panel 10. In addition, the panel 10 is disposed in the second mounting groove 112, and at this time, the outer surface of the panel 10 and the outer surface of the housing assembly 1 are smoothly transitioned, making the battery compartment more beautiful. It can be understood that although in the illustrated embodiment, the panel 10 and the first housing 11 are two independent parts connected to each other. However, in other embodiments, the panel 10 can also be integrally formed with the first housing 11.

[0059] As Figure 2 、 Figure 8 and Figure 9 As shown, the light guide plate 41 is strip-shaped, and the light source 40 is disposed on one side in the length direction of the light guide plate 41.

[0060] In some embodiments, as Figure 10 and Figure 11As shown, the light source 40 includes a lamp bead 400 disposed opposite to an end face (i.e., the first side surface 411) in the length direction of the light guide plate 41. The maximum width W1 of the lamp bead 400 is set to be less than the maximum width W2 of the light guide plate 41, and the thickness H1 of the lamp bead 400 is set to be less than or equal to the thickness H2 of the light guide plate 41. The lamp bead 400 does not extend beyond the top surface 412 of the light guide plate 41 and the two side surfaces in the width direction of the light guide plate 41, which is beneficial to making full use of the light of the lamp bead 400 and preventing light leakage at the same time. The ratio of the maximum width W1 of the lamp bead 400 to the maximum width W2 of the light guide plate 41 is 0.3 to 0.1, and the ratio of the thickness H1 of the lamp bead 400 to the thickness H2 of the light guide plate 41 is 0.5 to 1. Within this range, it is possible to ensure uniform light emission while ensuring that the effect light is bright enough. If it exceeds this range, there may be a phenomenon of inconsistent brightness and darkness at the light-transmitting part of the final product, thus affecting the overall effect. In addition, the space can be effectively utilized, making it visually brighter and easier for users to identify in a bright environment.

[0061] In some embodiments, the thickness H2 of the light guide plate 41 is 0.35 to 0.97 mm. If the thickness of the light guide plate 41 is too large, the product structure will be large, increasing the weight of the whole machine product. If it is too thin, the light scattering will be uneven, and the uniform light emission visible to the user cannot be achieved.

[0062] In some embodiments, the receiving hole 110 includes a first hole portion 1100 and a second hole portion 1101 communicating with the first hole portion 1100. The width A of the first hole portion 1100 is greater than the width B of the second hole portion 1101. The light guide plate 41 is disposed in the first hole portion 1100, and the light source 40 is disposed in the second hole portion 1101.

[0063] Figure 2 In the shown embodiment, the contour of the first hole portion 1100 is adapted to the outer contour of the light guide plate 41, the contour of the second hole portion 1101 is adapted to the outer contour of the light source 40, and the contour of the first mounting groove 111 is adapted to the outer contour of the first plate body 30; optionally, during the installation process, the light source 40 and the light guide plate 41 are first installed on the first plate body 30 of the flexible circuit board 3, and then the flexible circuit board 3 is installed in the battery compartment. Since the contours of the first hole portion 1100, the second hole portion 1101, and the first mounting groove 111 are respectively adapted to the outer contour of the light guide plate 41, the outer contour of the light source 40, and the outer contour of the first plate body 30, the installation of the flexible circuit board 3 is facilitated.

[0064] As Figure 9As shown, a groove 410 is provided on the first side surface 411 of the light guide plate 41 facing the light source 40. The second bottom surface 4100 of the groove 410 is integrally arc-shaped, increasing the area where light enters the light guide plate 41, thereby improving the light propagation efficiency. In other embodiments, the second bottom surface 4100 of the groove 410 may also be at least partially arc-shaped, such as S-shaped.

[0065] The panel 10 is entirely made of a light-transmitting material or at least a part of the panel 10 corresponding to the receiving hole 110 is made of a light-transmitting material, so as to facilitate the transmission of the light emitted by the light source 40 to the outside of the battery compartment. In some embodiments, the light-transmitting part on the panel 10 forms characters or patterns corresponding to the brand logo.

[0066] In some embodiments, the light source 40 includes at least one lamp bead 400, and the emission colors of all the lamp beads 400 are the same. When the emission colors of the lamp beads 400 are the same, the working state of the earphone can be reflected by means of the emission intensity or emission frequency of the light source 40.

[0067] In other embodiments, the light source 40 includes at least two lamp beads 400 with different emission colors, thereby enriching the visual effect of the battery compartment emitting light, and at the same time, the working state of the earphone can be reflected according to different emission colors.

[0068] The light-emitting module 4 further includes a reflector 42, and the reflector 42 is used to reflect the light of the light guide plate 41, making the light of the light guide plate 41 more uniform and improving the brightness to a certain extent. The reflector 42 is correspondingly arranged with the first bottom surface 413 and the outer peripheral surface 414 of the light guide plate 41. As Figure 4 and Figure 6 shown, the reflector 42 includes a side frame 420 correspondingly arranged with the outer peripheral surface 414 and a bottom plate 421 correspondingly arranged with the first bottom surface 413. The reflector 42 is provided with a notch 4204 for avoiding the light source 40 or surrounding the outside of the light source 40, so that the light of the light source 40 can enter the light guide plate 41.

[0069] In some embodiments, such as Figure 4 、 Figure 6 、 Figure 10 and Figure 12As shown, the outer peripheral surface 414 of the light guide plate 41 includes a first side surface 411 disposed opposite to the light source 40. The light reflector 42 is coated on the surface of the light guide plate 41 except for the first side surface 411 and the top surface 412, and can be fixedly connected by means such as gluing. The side frame 420 of the light reflector 42 includes a first side plate 4200, a second side plate 4201, and a third side plate 4202. The first side plate 4200, the second side plate 4201, and the third side plate 4202 are connected to each other. At this time, a notch 4204 for avoiding the light source 40 is formed at one end of the side frame 420, and the notch 4204 is disposed corresponding to the first side surface 411; the outer peripheral surface 414 of the light guide plate 41 further includes a second side surface 415, a third side surface 416, and a fourth side surface 417. The first side plate 4200, the second side plate 4201, and the third side plate 4202 are respectively disposed corresponding to the second side surface 415, the third side surface 416, and the fourth side surface 417. It can be understood that in other embodiments, the light reflector 42 can also partially extend onto the first side surface 411 to form a notch 4204 for avoiding the light source 40.

[0070] In some other embodiments, such as Figure 13 and Figure 14 As shown, the light reflector 42 is coated on the surface of the light guide plate 41 except for the top surface 412 and the first side surface 411, and surrounds the outside of the light source 40. At this time, the side frame 420 of the light reflector 42 further includes a fourth side plate 4203 disposed corresponding to the first side surface 411, and the fourth side plate 4203 and the first side surface 411 do not contact each other and are disposed outside the light source 40; the first side plate 4200, the second side plate 4201, the third side plate 4202, and the fourth side plate 4203 are connected to each other. At this time, the side frame 420 forms a closed loop, and the side frame 420 is connected to the bottom plate 421. The light guide plate 41 and the light source 40 are disposed in the cavity formed by the light reflector 42; the light radiating outside the light guide plate 41 in the circumferential direction can be reflected by the light reflector 42 into the light guide plate 41, thereby improving the propagation efficiency of the light source 40.

[0071] The light emitted by the light source 40 propagates from the first side surface 411 into the light guide plate 41, and the light reflector 42 reflects the light emitted from the periphery of the light guide plate 41, so that the brightness of the light guide plate 41 is brighter and more uniform. When the light passes through the top surface 412 and the panel 10 and propagates to the outside of the battery compartment, a better light-emitting effect can be obtained.

[0072] In some embodiments, the light source 40 includes at least two lamp beads 400. The outer peripheral surface 414 is formed by enclosing a plurality of side surfaces. At least two lamp beads 400 are disposed corresponding to different side surfaces, so as to improve the brightness of the battery compartment when it emits light. The light reflector 42 is disposed corresponding to the first bottom surface 413 and the outer peripheral surface 414 of the light guide plate 41, and the light reflector 42 is provided with a notch for avoiding the light source 40 or surrounds the outside of the light source 40.Figure 15 In the illustrated embodiment, the light source 40 includes three lamp beads 400. The three lamp beads 400 are correspondingly arranged with two different side surfaces. The reflecting member 42 is coated on the surface of the light guide plate 41 except for the top surface 412, and is provided with two notches 4204 that avoid the light source 40. In other embodiments, the side frame 420 can also be annular, enclosing the light guide plate 41 and the light source 40.

[0073] As Figure 16 As shown, the present utility model also proposes a bone conduction headset, which includes the battery compartment as described above.

[0074] The bone conduction headset further includes a control compartment 5 and a rear hanger 7 connected between the control compartment 5 and the battery compartment. The rear hanger 7 includes a wire electrically connected to the light source 40 and the control circuit board in the control compartment 5 to transmit the light emission control signal of the control circuit board. When the bone conduction headset is worn, the panel 10 of the battery compartment does not contact the human body, and is arranged on the side of the battery compartment away from the human body, so as to effectively transmit the light generated by the light source 40 to the outside of the battery compartment for external personnel to observe.

[0075] Figure 16 In the illustrated embodiment, the bone conduction headset further includes a first earphone head 60, a second earphone head 61, a first ear hook 80 connected between the control compartment 5 and the first earphone head 60, and a second ear hook 81 connected between the battery compartment and the second earphone head 61. Wires are also arranged in the first ear hook 80 and the second ear hook 81 to achieve electrical connection between the control compartment 5, the battery compartment, the first earphone head 60, and the second earphone head 61 through the wires, so as to realize the control of the earphone heads and provide energy.

[0076] The above is only the specific embodiment of the present utility model, and any improvement made on the premise of the conception of the present utility model is regarded as the protection scope of the present utility model.
