However, with the reduction in size, the rationality of the internal structure of the charging case has also encountered certain problems. Some existing charging cases do not have a reasonable arrangement of the LEDs used to display the battery level, resulting in poor battery level display and failing to provide users with intuitive battery level feedback. Summary of the Invention

[0004] Firstly, this application provides a wireless microphone charging case to improve the problem of its unreasonable internal structure and enhance the power display effect.

[0005] The present invention provides a wireless microphone charging case, comprising: a housing having a display hole that extends through in a first direction; a PCB board disposed within the housing; an LED light group disposed within the PCB board; a light guide disposed within the housing; and a light-emitting bead disposed within the light guide and located in the display hole; wherein a light-guiding channel is formed between the LED light group and the light guide, and the LED light group and the light-emitting bead are staggered in the first direction.

[0006] Optionally, the wireless microphone charging case includes a light-focusing element connected to the PCB board or the housing, and the light-focusing element includes a first light-focusing portion protruding toward the light guide; the LED light group includes multiple LED beads, and the first light-focusing portion is provided between two adjacent LED beads.

[0008] Optionally, the light guide includes a plurality of light guide portions, each of which is provided with a light-emitting bead; the number of the plurality of LED beads is the same as the number of the plurality of light guide portions, and the positions of the plurality of LED beads and the plurality of light guide portions correspond one-to-one.

[0009] Optionally, the light guide is provided with a plurality of first limiting grooves, and a first limiting groove is provided between two adjacent light guides; the housing is provided with a first limiting part, and the first limiting part is located in the first limiting groove.

[0010] Optionally, the light guide is further provided with a second limiting groove; the housing is provided with a second limiting part, the second limiting part being located in the second limiting groove; the first limiting part protrudes along a first direction, and the second limiting part protrudes along a second direction; the second direction is perpendicular to the first direction.

[0011] Optionally, the edge region of the light guide is further provided with a third limiting groove, the housing is provided with a third limiting part, and the third limiting part is located in the third limiting groove; the area of ​​the light guide facing the third limiting groove is provided with a guiding arc surface.

[0012] Optionally, the wireless microphone charging case further includes a cover, which is rotatably connected to the housing; the cover is provided with a first stop, and the housing is provided with a second stop; the cover includes an open state and a closed state; in the open state, the first stop is used to abut against the second stop; in the closed state, the first stop and the second stop are at a preset distance.

[0014] Optionally, the housing is provided with a receiving groove, and the second stop is located on the side of the receiving groove facing the closing direction; in the open state, the first stop is located in the receiving groove.

[0015] The wireless microphone charging case of this invention includes a housing, a PCB board, an LED light assembly, a light guide, and a display bead. The LED light assembly is mounted on the PCB board, thus integrating the LED light assembly onto the PCB board, reducing the need for traditional separate LED light boards, simplifying the internal structure of the charging case, and making the wireless microphone charging case more compact and smaller in size. Furthermore, the housing has a display hole that extends in a first direction. The display bead is located on the light guide and within the display hole. A light guide channel exists between the LED light assembly and the light guide, and in the first direction, the LED light assembly and the display bead are staggered. With this structure, when the LED light assembly emits light, the light can illuminate the light guide through the light guide channel, and the display bead, located on the light guide, allows the user to observe the light and thus monitor the battery status. Because the LED light group and the light-emitting bead are staggered in the first direction, the user is less likely to see the LED light group inside the housing directly from the light-emitting bead, thus reducing the visual interference of LED flicker and halo on the user. Therefore, the wireless microphone charging case provided by this invention has a compact structure and a reasonable internal structure, enabling the user to experience a clearer visual effect when checking the battery status.

[0016] Secondly, this application also provides a wireless microphone charging case and a wireless microphone charging system, which can solve the problem in the related technology that the wireless microphone charging case is difficult to maintain in the open state of the top cover due to the lack of rotation support, which is inconvenient for users.

[0020] This application provides a wireless microphone charging system that solves the problem of large overall size of wireless microphone charging systems caused by the size difference between the transmitter and receiver in related technologies.

[0161] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0162] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0163] First Embodiment

[0164] Referring to Figures 1 to 3, this application provides a wireless microphone charging case, which includes a housing 1, a PCB board 2, an LED light group 3, a light guide 4, and a light-emitting bead 5. The housing 1 is provided with a display hole 11, which is through in a first direction. The PCB board 2 is disposed inside the housing 1. The LED light group 3 is disposed on the PCB board 2. The light guide 4 is disposed inside the housing 1. The light-emitting bead 5 is disposed on the light guide 4 and located inside the display hole 11. A light guide channel is provided between the LED light group 3 and the light guide 4, and the LED light group 3 and the light-emitting bead 5 are staggered in the first direction.

[0165] According to the above structure, the present invention integrates the LED light group 3 onto the PCB board 2, reducing the need for traditional independent LED light boards and simplifying the internal structure of the charging case, making the wireless microphone charging case more compact and smaller in size. Furthermore, the housing 1 has a display hole 11 that extends through in the first direction. The light-emitting bead 5 is disposed on the light guide 4 and located within the display hole 11. A light guide channel exists between the LED light group 3 and the light guide 4, and the LED light group 3 and the light-emitting bead 5 are staggered in the first direction. With this structure, when the LED light group 3 emits light, the light can illuminate the light guide 4 through the light guide channel, and the light-emitting bead 5 is located on the light guide 4. The user can observe the light by looking at the light-emitting bead 5 to monitor the battery status. Because the LED light group 3 and the light-emitting bead 5 are staggered in the first direction, the user is less likely to directly see the LED light group 3 inside the housing 1 from the light-emitting bead 5, thus reducing the visual interference of LED flicker and halo on the user. Therefore, the wireless microphone charging case provided by this invention has a compact structure and a reasonable internal structure, which enables users to experience a clearer visual effect when checking the battery status.

[0166] Specifically, integrating the LED light group 3 onto the PCB board 2 can also reduce production costs. Reducing the need for traditional separate LED light boards simplifies the assembly process, lowering manufacturing costs and time. Furthermore, integrating the LED light group 3 onto the PCB board 2 reduces connecting wires, thus reducing potential connection failure points and lowering the risk of malfunctions due to poor contact or damaged connecting wires.

[0167] It should be noted that the light guide channel refers to the interconnected light propagation channel formed between the LED light group 3 and the light guide element 4. The outline structure of this light guide channel is not limited; it only requires that there are no obstructions between the LED light group 3 and the light guide element 4, allowing the light from the LED light group 3 to directly reach the light guide element 4. Both the light guide element 4 and the light-emitting bead 5 are made of transparent light-transmitting material, allowing the light from the LED light group 3 to pass through them.

[0168] For ease of description, in the wireless microphone charging case, the side of the display hole 11 facing away from the opening of the housing 1 is defined as the bottom. Thus, referring to Figures 9 and 11, the first direction is the X direction in the figures. In the first direction, the LED light group 3 and the light-emitting bead 5 are offset, which can be understood as the LED light group 3 being located below the light-emitting bead 5. Of course, in some examples, the LED light group 3 may also be located above, to the left, or to the right of the light-emitting bead 5; in short, the LED light group 3 and the light-emitting bead 5 will not be in the same first direction.

[0169] Referring to Figures 3 and 4, in some embodiments, the wireless microphone charging case includes a light-focusing element 6, which is connected to the PCB board 2 or the housing 1. The light-focusing element 6 includes a first light-focusing portion 61 protruding toward the light guide element 4. The LED light group 3 includes a plurality of LED beads 31, with the first light-focusing portion 61 positioned between two adjacent LED beads 31. Thus, the first light-focusing portion 61 separates two adjacent LED beads 31, preventing the light from interfering with each other and avoiding issues such as scattering and halos that can easily occur when the LED beads 31 are arranged in a concentrated manner, thus affecting clarity.

[0170] In some examples, the LED group 3 may include four LED beads 31. When all LED beads 31 are lit, it indicates that the battery is fully charged. When only three LED beads 31 are lit, it indicates that the battery is about 75% remaining.

[0171] Referring to Figure 4, in some examples, the two outermost LED beads 31 may also be provided with a first focusing part 61, so that a first focusing part 61 is provided on both sides of each LED bead 31.

[0172] Referring to Figure 4, in some embodiments, the light-concentrating element 6 further includes a second light-concentrating section 62; the second light-concentrating section 62 is located on the side of the first light-concentrating section 61 facing away from the light guide element 4, and the second light-concentrating section 62 connects two adjacent first light-concentrating sections 61. Thus, the first light-concentrating sections 61 and the second light-concentrating section 62 together form a U-shaped structure, with the opening facing the light guide element 4. Accordingly, the U-shaped space formed by the light-concentrating element 6 can form the aforementioned light-guiding channel to the light guide element 4, and the cooperation of the first light-concentrating section 61 and the second light-concentrating section 62 not only enhances the light-gathering ability but also reduces light loss and scattering during propagation, allowing the light from the LED beads 31 to be accurately guided to the light guide element 4, ensuring a more concentrated and brighter light output, and improving the brightness and contrast of the light. When users check the battery status of the charging case, they can experience a clearer and more intuitive visual effect, making it easier to identify.

[0173] In some examples, the first light-concentrating part 61 and the second light-concentrating part 62 can be integrally formed.

[0174] Referring to Figures 5 and 6, in some embodiments, the light guide 4 includes multiple light guide sections 41, each light guide section 41 having a light-emitting bead 5; the number of multiple LED beads 31 is the same as the number of multiple light guide sections 41, and the positions of the multiple LED beads 31 and the multiple light guide sections 41 correspond one-to-one. Therefore, in conjunction with the light-focusing member 6, the light from each LED bead 31 can be independently propagated to the corresponding light guide section 41, ensuring the accuracy of the light display.

[0175] Referring to Figures 5 to 8, in some embodiments, the light guide 4 is provided with multiple first limiting grooves 43, and a first limiting groove 43 is provided between two adjacent light guide portions 41; the housing 1 is provided with a first limiting portion 12, which is located within the first limiting groove 43. Thus, the first limiting portion 12 can be embedded within the first limiting groove 43, thereby restricting the movement of the light guide 4 and ensuring its stable installation within the housing 1. Furthermore, as a portable product, the stable installation of the wireless microphone charging case reduces damage caused by vibration. In addition, the first limiting groove 43 is located between two adjacent light guide portions 41, thus isolating them. Especially with the first limiting portion 12 inserted into the first limiting groove 43, this isolation effect is further enhanced. The first limiting portion 12 forms a barrier between adjacent light guide portions 41, effectively preventing light overflow and mixing between different light guide portions 41, further ensuring the accuracy of the light display.

[0176] Referring to Figures 5 and 7, in some embodiments, one side of the first limiting groove 43 is open to the outside in the second direction; the second direction is perpendicular to the first direction. The second direction can be the direction of the Y-axis in the figures. For ease of description, the side of the first limiting groove 43 that is open to the outside is defined as the inlet. Specifically, when the light guide 4 is assembled to the housing 1, the first limiting part 12 can be inserted through the inlet. When the operator pushes the light guide 4 in the second direction, the first limiting part 12 can slide relative to the outside, sliding into the first limiting groove 43, so that the first limiting part 12 is completely embedded in the first limiting groove 43. Thus, the fact that one side of the first limiting groove 43 is open to the outside makes the installation of the light guide 4 more convenient and faster.

[0177] Referring to Figures 4 and 6, in some embodiments, the first limiting portion 12 protrudes towards the first focusing portion 61 and abuts against the first focusing portion 61. Therefore, the first limiting portion 12 abutting against the first focusing portion 61 further enhances the focusing effect of the light guide channel. Specifically, when the first limiting portion 12 abuts against the first focusing portion 61, it further encloses the light guide channel, allowing the light from the LED beads 31 to be precisely guided to the light guide member 4, further ensuring a more concentrated light output. Thus, not only is the light focusing ability enhanced in the U-shaped space formed by the focusing member 6, but the placement of the first limiting portion 12 abutting against the first focusing portion 61 further improves the light focusing ability.

[0178] Of course, in other embodiments, the first limiting portion 12 protrudes toward the first focusing portion 61, and there is a gap between the first limiting portion 12 and the first focusing portion 61. This gap can be set small enough to ensure that it does not significantly affect the focusing of light. At the same time, this gap provides the necessary tolerance for the installation process. An appropriate gap allows for fine-tuning during installation, reducing the stringent requirements for precise alignment.

[0179] In some embodiments, the light guide 4 includes a light guide portion 41 and a light shield 42 connected to each other; a light-emitting bead 5 is disposed on the light guide portion 41, and the light from the LED light group 3 passes through the light guide portion 41 to reach the light-emitting bead 5. The light shield 42 is used to block the light from the LED light group 3. Thus, the light shield 42 can block the light from passing through, thereby allowing the light to pass through the light guide portion 41 more concentratedly, resulting in brighter illumination and higher brightness when the light reaches the light-emitting bead 5. In addition, it is understood that the area closer to the LED light group 3 has higher brightness. To prevent the light in this area from passing through and escaping outside the housing 1, affecting the user's visual experience, this embodiment uses the light shield 42 to block unnecessary strong light that may pass through the housing 1. Specifically, the light shield 42 is made of an opaque material.

[0180] Referring to Figures 5 to 7, in some embodiments, the light guide 4 is further provided with a second limiting groove 44; the housing 1 is provided with a second limiting part 13, which is located within the second limiting groove 44; the first limiting part 12 protrudes along a first direction, and the second limiting part 13 protrudes along a second direction; the second direction is perpendicular to the first direction. The second direction can be the direction of the Y-axis in the figure. Thus, the cooperation of the first limiting part 12 and the second limiting part 13 can limit the light guide 4 in different directions, ensuring that the light guide 4 is fixed in multiple directions within the housing 1. Furthermore, the multi-directional limiting also improves the installation accuracy of the light guide 4, ensuring that each light guide part 41 can be accurately aligned with its corresponding LED bead 31, thereby achieving the best light transmission effect.

[0181] In some examples, the first direction can be parallel to the horizontal plane, and the second direction can be perpendicular to the horizontal plane. Thus, the cooperation of the first limiting part 12 and the second limiting part 13 not only prevents the light guide 4 from moving in the horizontal direction but also restricts its displacement in the vertical direction. This multi-directional limiting design greatly improves the stability of the light guide 4, ensuring that it is not easily displaced by external vibrations or other factors during use, enhancing the product's durability, extending its service life, and reducing the frequency of maintenance and replacement.

[0182] Referring to Figures 5 and 6, in some embodiments, the edge region of the light guide 4 is further provided with a third limiting groove 45, and the housing 1 is provided with a third limiting part 14, which is located within the third limiting groove 45; the area of ​​the light guide 4 facing the third limiting groove 45 is provided with a guiding arc surface. Thus, the third limiting groove 45 is located at the edge, making it easier to align the light guide 4 during installation. During operation, the installer can quickly find the correct installation position through the edge third limiting groove 45, saving installation time. Furthermore, the guiding arc surface also facilitates the placement of the third limiting part 14 into the third limiting groove 45. The guiding arc surface not only provides a natural visual guide path but also provides a smooth transition for the third limiting part 14 to enter the third limiting groove 45 during installation, effectively reducing possible jamming or misalignment during installation and ensuring that the limiting part can smoothly enter the third limiting groove 45.

[0183] In related technologies, during daily use, some charging case lids tend to close automatically under gravity. Incorrect closure can not only cause inconvenience for users when taking out or putting away the wireless microphone, but may also accidentally pinch fingers or damage the device.

[0184] Referring to Figures 9 to 12, in some embodiments, the wireless microphone charging case further includes a cover 7, which is rotatably connected to the housing 1. The cover 7 has a first stop 71, and the housing 1 has a second stop 15. The cover 7 has an open state and a closed state. In the open state, the first stop 71 abuts against the second stop 15. In the closed state, there is a preset distance between the first stop 71 and the second stop 15. Therefore, when the cover 7 is in the open state, since the first stop 71 can abut against the second stop 15, there is a certain resistance when the cover 7 needs to switch from the open state to the closed state, making it difficult for the cover 7 to close automatically under the action of gravity. It is understood that, in order to facilitate the user to close the cover 7, the contact surface between the first stop 71 and the second stop 15 is small, which can provide a certain resistance to the cover 7 when it closes under the action of gravity to prevent the cover 7 from closing. However, this resistance is relatively small, and there will be no obvious obstruction when the user needs to manually close the cover 7.

[0185] Specifically, the first stop 71 and / or the second stop 15 can be made of elastic material. When the user needs to close the cover 7, a slight external force can be applied to deform the first stop 71 and / or the second stop 15, allowing the first stop 71 to pass over the contact surface with the second stop 15, and then the cover 7 closes. When the cover 7 needs to be opened, the user will apply external force to open the cover 7. At this time, the cover 7 performs a reverse action, and after the first stop 71 passes over the contact surface with the second stop 15, the cover 7 is in the open state.

[0186] Referring to Figures 9 and 10, in some embodiments, the cover 7 is provided with a rotating part 72, and the cover 7 is provided with a rotating shaft 73 passing through the rotating part 72. The two ends of the rotating shaft 73 are connected to the housing 1, and the cover 7 can rotate around the rotating shaft 73. A first stop part 71 is provided on the rotating part 72. When the cover 7 rotates, the rotating part 72 and the first stop part 71 rotate accordingly. When the cover 7 switches from an open state to a closed state, the first stop part 71 rotates and abuts against the second stop part 15. With a slight external force from the user, the first stop part 71 can pass over the contact surface with the second stop part 15. As the first stop part 71 continues to rotate, it gradually moves away from the second stop part 15. When the cover 7 is in the closed state, there is a preset distance between the first stop part 71 and the second stop part 15, creating a gap between them.

[0187] In some embodiments, the first stop 71 has an arcuate surface on the side facing the second stop 15. In other embodiments, the second stop 15 has an arcuate surface on the side facing the first stop 71. Specifically, the arcuate surface can also be the contact area between the first stop 71 and the second stop 15. Thus, when the cover 7 rotates, the first stop 71 needs to cross the contact surface with the second stop 15, and the arcuate surface design effectively reduces the friction between the first stop 71 and the second stop 15, providing a natural transition path, making the contact and separation of the first stop 71 and the second stop 15 smoother, reducing friction and wear.

[0188] Referring to Figures 9 and 10, in some embodiments, the housing 1 is provided with a receiving groove 16, and the second stop 15 is located on the side of the receiving groove 16 facing the closing direction; in the open state, the first stop 71 is located within the receiving groove 16. Thus, the receiving groove 16 provides a space for the first stop 71. When the cover 7 is in the open state, the first stop 71 can be received within the receiving groove 16 and will not contact the second stop 15, thus preventing the first stop 71 from abutting against the second stop 15 for an extended period, causing wear between them. Specifically, the size of the receiving groove 16 can be adaptively designed according to the size of the first stop 71. The closing direction defined in this embodiment is the direction of movement of the cover 7 when it rotates from the open state to the closed state.

[0189] In some examples, housing 1 may include an outer shell 18 and an inner shell 17, with the inner shell 17 disposed within the outer shell 18 and used to house the wireless microphone. A receiving groove 16 and a second stop 15 are disposed in the inner shell 17, and a first limiting part 12, a second limiting part 13, and a third limiting part 14 are disposed in the outer shell 18.

[0190] In the wireless microphone charging case provided in this application, the LED light group 3 is integrated on the PCB board 2, reducing the need for traditional independent LED light boards and simplifying the internal structure of the charging case, making the wireless microphone charging case more compact and smaller in size. Furthermore, the housing 1 has a display hole 11 that extends through in a first direction. A light-emitting bead 5 is disposed on the light guide 4 and located within the display hole 11. A light guide channel exists between the LED light group 3 and the light guide 4, and the LED light group 3 and the light-emitting bead 5 are staggered in the first direction. With this structure, when the LED light group 3 emits light, the light can illuminate the light guide 4 through the light guide channel. Since the light-emitting bead 5 is located on the light guide 4, the user can observe the light by looking at the light-emitting bead 5 to monitor the battery status. Because the LED light group 3 and the light-emitting bead 5 are staggered in the first direction, the user is less likely to directly see the LED light group 3 inside the housing 1 from the light-emitting bead 5, thus reducing the visual interference of LED flicker and halo on the user. Therefore, the wireless microphone charging case provided by this invention has a compact structure and a reasonable internal structure, which enables users to experience a clearer visual effect when checking the battery status.

[0191] Second Embodiment

[0192] Please refer to Figures 13-15. In the first aspect, this application proposes a wireless microphone charging case 1, which can improve the convenience of user use.

[0193] The wireless microphone charging case 1 includes a case body 10, a top cover 20, and a rotating assembly 30. The case body 10 has a compartment opening 10a. The top cover 20 has a first state with the compartment opening 10a open and a second state with the compartment opening 10a closed, and the top cover 20 is adapted to switch between the first state and the second state. The rotating assembly 30 includes a fixed base 31, a rotating base 32, and an elastic member 33; the fixed base 31 is connected to the case body 10; the rotating base 32 is connected to the top cover 20, and the rotating base 32 is rotatably connected to the fixed base 31; the first end of the elastic member 33 is connected to the fixed base 31, and the second end of the elastic member 33 is connected to the rotating base 32, and the elastic member 33 is adapted to undergo elastic deformation when the top cover 20 rotates. The specific structure of the wireless microphone charging case 1 will be described in detail below with reference to Figures 13-22. As shown in Figures 13-15, the wireless microphone charging case 1 includes a case body 10, a top cover 20, and a rotating assembly 30. The case body 10 serves as the shell of the wireless microphone charging case 1. The specific shape of the housing 10 is not limited here, and designers can design it reasonably according to actual needs; for example, the outer contour shape of the housing 10 can be, but is not limited to, a cuboid or a cylinder-like shape. The specific material used to manufacture the housing 10 is also not limited here, and designers can choose it reasonably according to actual needs; for example, the material used to manufacture the housing 10 can be, but is not limited to, plastic or PVC; thus, the raw materials are widely available and easy to obtain, and can effectively reduce the cost of the wireless microphone charging housing 1.

[0194] The housing 10 has a housing opening 10a; the housing opening 10a is the opening in the housing 10 for the wireless microphone 2 to be inserted into the microphone mounting position 10b of the housing 10 (i.e., the area inside the housing 10 for accommodating the wireless microphone 2, such as a mounting slot).

[0195] The top cover 20 serves as the lid of the wireless microphone charging case 1. The specific shape of the top cover 20 is not limited here; designers can design it appropriately according to actual needs. For example, the outer contour of the top cover 20 can be, but is not limited to, a cuboid or cylinder-like shape. The specific material used to manufacture the top cover 20 is also not limited here; designers can choose appropriately according to actual needs. For example, the material used to manufacture the top cover 20 can be, but is not limited to, plastic or PVC. This ensures that the raw materials are widely available and easily accessible, and effectively reduces the cost of the wireless microphone charging case 1.

[0196] The top cover 20 has a first state and a second state. In the first state, the top cover 20 opens the opening 10a of the compartment 10, allowing the user to remove the wireless microphone 2 stored in the microphone mounting position 10b of the compartment 10 for use, or to insert the used wireless microphone 2 into the microphone mounting position 10b of the compartment 10. In the second state, the top cover 20 closes the opening 10a of the compartment 10, allowing the controller of the wireless microphone charging case 1 (not shown in the figure, but described below) to control the battery (not shown in the figure) of the wireless microphone charging case 1 to charge the wireless microphone 2 stored in the microphone mounting position 10b of the compartment 10, depending on the actual situation. The top cover 20 can switch between the first state and the second state.

[0197] As shown in Figures 15-17, the rotating component 30 serves as a connecting structure for the wireless microphone charging case 1, connecting the top cover 20 and the case body 10; the rotating component 30 includes a fixed base 31, a rotating base 32, and an elastic element 33.

[0198] The fixing base 31 serves as one of the connecting seats of the rotating assembly 30. The specific structure of the fixing base 31 is not limited here; designers can design it reasonably according to actual needs. For example, the fixing base 31 can be, but is not limited to, a plate-like structure. The specific material used to manufacture the fixing base 31 is not limited here; designers can choose it reasonably according to actual needs. For example, the material used to manufacture the fixing base 31 can be, but is not limited to, plastic or PVC; this ensures that the raw materials are widely available and easily accessible, and can effectively reduce the cost of the wireless microphone charging case 1. It should be noted that the material used to manufacture the fixing base 31 can be the same as or different from the material used to manufacture the case body 10.

[0199] The fixing seat 31 is connected to the chamber body 10. The specific connection method between the fixing seat 31 and the chamber body 10 is not limited here. Designers can make reasonable designs according to actual needs. For example, the fixing seat 31 can be detachably connected to the chamber body 10 by at least one of the following methods: screw connection, snap connection or plug connection. Alternatively, the fixing seat 31 can also be non-detachably connected to the chamber body 10 by riveting, gluing, injection molding or 3D printing.

[0200] The rotating base 32 serves as another connecting seat for the rotating assembly 30. The specific structure of the rotating base 32 is not limited here; designers can design it appropriately according to actual needs. For example, the rotating base 32 can be, but is not limited to, an angled base structure. The specific material used to manufacture the rotating base 32 is not limited here; designers can choose appropriately according to actual needs. For example, the material used to manufacture the rotating base 32 can be, but is not limited to, plastic or PVC; this ensures that the raw materials are widely available and easily accessible, and effectively reduces the cost of the wireless microphone charging case 1. It should be noted that the material used to manufacture the rotating base 32 can be the same as or different from the material used to manufacture the top cover 20.

[0201] The rotating base 32 is connected to the top cover 20. The specific connection method between the rotating base 32 and the top cover 20 is not limited here. Designers can make reasonable designs according to actual needs. For example, the rotating base 32 can be detachably connected to the top cover 20 by at least one of the following methods: screw connection, snap connection, or plug connection. Alternatively, the rotating base 32 can also be non-detachably connected to the top cover 20 by riveting, gluing, injection molding, or 3D printing.

[0202] The rotating base 32 is rotatably connected to the fixed base 31; thus, a rotatable connection is achieved between the top cover 20 and the compartment 10, and the top cover 20 can be switched between the first state and the second state by flipping it. For example, the rotating assembly 30 may also include a rotating shaft 34, through which the rotating base 32 is rotatably connected to the fixed base 31.

[0203] The elastic element 33, acting as an enabling element of the rotating assembly 30, serves two purposes: firstly, to maintain the position of the top cover 20 in the aforementioned first / second states; and secondly, to drive the top cover 20 to switch between the first and second states. The specific material used to manufacture the elastic element 33 is not limited here; designers can choose a suitable material based on actual needs. For example, the material used to manufacture the elastic element 33 can be, but is not limited to, carbon steel, low-manganese steel, silicon-manganese steel, chromium-vanadium steel, and metallic nickel. The specific manifestations of the elastic element 33 will be described in detail below.

[0204] The first end of the elastic element 33 is connected to the fixed seat 31, and the second end of the elastic element 33 is connected to the rotating seat 32. The specific connection method between the elastic element 33 and the fixed seat 31 / rotating seat 32 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the elastic element 33 can be fixedly connected to the fixed seat 31 / rotating seat 32, or it can be rotatably connected to the fixed seat 31 / rotating seat 32. It is also understood that the specific connection method between the elastic element 33 and the fixed seat 31 / rotating seat 32 is not the same for different specific forms of elastic element 33.

[0205] The elastic element 33 is adapted to undergo elastic deformation when the top cover 20 rotates; that is, as long as the position of the top cover 20 relative to the compartment 10 changes, the elastic element 33 will undergo elastic deformation. It can be understood that when the top cover 20 is in the first state described above, the position of the top cover 20 relative to the compartment 10 is fixed, so the elastic element 33 will not undergo elastic deformation; similarly, when the top cover 20 is in the second state described above, the position of the top cover 20 relative to the compartment 10 is also fixed, so the elastic element 33 will not undergo elastic deformation. Thus, when the user needs to switch the top cover 20 from the first state to the second state, the elastic element 33 will undergo elastic deformation during the rotation of the top cover 20. Therefore, the force exerted by the user on the top cover 20 needs to overcome the reaction force corresponding to the elastic deformation of the elastic element 33 in order to allow the top cover 20 to rotate in a direction biased towards the opening 10a of the compartment 10 to switch from the first state to the second state. Similarly, when the user needs to switch the top cover 20 from the second state to the first state, the elastic element 33 will undergo elastic deformation during the rotation of the top cover 20. Therefore, the force exerted by the user on the top cover 20 also needs to overcome the reaction force corresponding to the elastic deformation of the elastic element 33 in order to allow the top cover 20 to rotate in a direction biased towards the opening 10a of the compartment 10 to switch from the second state to the first state.

[0206] Based on the wireless microphone charging case 1 in this application, a fixed base 31 and a rotating base 32 are designed so that the top cover 20 is rotatably connected to the fixed base 31 via the rotating base 32 to achieve a rotatable connection between it and the case body 10. By designing the elastic element 33 to be suitable for elastic deformation when the top cover 20 rotates, when the top cover 20 is in the first state, since the position of the top cover 20 relative to the case body 10 is fixed, the elastic element 33 will not produce elastic deformation. At this time, the elastic element 33 provides support for the top cover 20 so that the top cover 20 can be maintained in the first state, thereby facilitating user use.

[0207] As shown in Figures 15-17, the first end of the elastic element 33 is rotatably connected to the fixed end of the fixed seat 31 near the fixed end of the rotating seat 32, and the rotation axis of the first end of the elastic element 33 is eccentrically set relative to the rotation axis of the rotating seat 32; the second end of the elastic element 33 is rotatably connected to the free end of the rotating seat 32. The rotation axis of the first end of the elastic element 33 forms a first intersection point P1 in a plane perpendicular to the rotation axis of the rotating seat 32; the rotation axis of the second end of the elastic element 33 forms a second intersection point P2 in the same plane; the first intersection point P1 and the second intersection point P2 are used to form a first connecting line L1, and the elastic element 33 is adapted to generate elastic deformation along the direction of the first connecting line L1 when the top cover 20 rotates.

[0208] It is understood that the rotation axis of the rotating seat 32 forms a third intersection point P3 in the aforementioned plane, and the third intersection point P3 and the second intersection point P2 are used to form the second connecting line L2.

[0209] As shown in Figures 18-20, trajectory M is a circular trajectory formed with the first intersection point P1 as the center and the first connecting line L1 as the radius when the top cover 20 is in the first state / second state mentioned above; trajectory N is a circular trajectory formed with the third intersection point P3 as the center and the second connecting line L2 as the radius when the top cover 20 is in the first state / second state mentioned above. Trajectory M and trajectory N intersect to form a fourth intersection point P4 and a fifth intersection point P5. The fourth intersection point P4 and the third intersection point P3 form a third connecting line L3, and the fifth intersection point P5 and the third intersection point P3 form a fourth connecting line L4. The third connecting line L3 and the fourth connecting line L4 form a rotation angle α.

[0210] As shown in Figure 18, Figure 18 is a cross-sectional structural schematic diagram of the top cover 20 in the first state in one embodiment of this application. As can be seen from Figure 18, the position of the top cover 20 relative to the compartment 10 is fixed at this time, the second intersection point P2 coincides with the fourth intersection point P4, and the elastic member 33 does not produce elastic deformation (that is, it is in a natural elongation state).

[0211] As shown in Figure 19, Figure 7 is a cross-sectional structural schematic diagram of the top cover 20 in one position during the process of switching from the first state (second state) to the second state (first state) in one embodiment of this application. As can be seen from Figure 7, at this time, the top cover 20 rotates relative to the compartment 10 to the position shown in the figure, the second intersection point P2 is separated from the trajectory M and falls inside the trajectory M, and the elastic member 33 is compressed and produces elastic deformation.

[0212] As shown in Figure 20, Figure 20 is a cross-sectional structural schematic diagram of the top cover 20 in the second state in one embodiment of this application. As can be seen from Figure 20, the position of the top cover 20 relative to the compartment 10 is fixed at this time, the second intersection point P2 coincides with the fifth intersection point P5, and the elastic member 33 does not produce elastic deformation (that is, it is in a natural elongation state).

[0213] It should be noted that, as shown in Figure 19, during the process of the top cover 20 switching from the first state to the second state, the elastic element 33 is always in a state of being compressed and generating elastic deformation. Specifically, when the top cover 20 rotates from the first state to the position of half rotation angle α, the elastic element 33 is compressed and the elastic deformation generated by the elastic element 33 gradually increases until the top cover 20 rotates to the position of half rotation angle α, at which point the elastic deformation generated by the compression of the elastic element 33 reaches its maximum. When the top cover 20 rotates from the position of half rotation angle α to the second state, the elastic element 33 is compressed and the elastic deformation generated by the elastic element 33 gradually decreases from its maximum and eventually decreases to zero (that is, when the top cover 20 is in the second state). Similarly, during the process of the top cover 20 switching from the second state to the first state, the elastic element 33 is always in a state of being compressed and undergoing elastic deformation. Specifically, when the top cover 20 rotates from the second state to the position of half rotation angle α, the elastic element 33 is compressed and the elastic deformation of the elastic element 33 gradually increases until the top cover 20 rotates to the position of half rotation angle α, at which point the elastic deformation of the elastic element 33 reaches its maximum. When the top cover 20 rotates from the position of half rotation angle α to the first state, the elastic element 33 is compressed and the elastic deformation of the elastic element 33 gradually decreases from its maximum and eventually decreases to zero (that is, when the top cover 20 is in the first state).

[0214] As shown in Figures 18-20, when the top cover 20 switches from the first state to the second state, during the first half of the closing process (i.e., the process of rotating from the first state to the position of half rotation angle α), the top cover 20 is subjected to a reaction force corresponding to the gradually increasing elastic deformation caused by the compression of the elastic element 33. This reaction force effectively maintains the first state of the top cover 20. During the second half of the closing process (i.e., the process of rotating from the position of half rotation angle α to the second state), the top cover 20 is subjected to a reaction force corresponding to the gradually decreasing elastic deformation caused by the compression of the elastic element 33. This reaction force facilitates the top cover 20 to rotate towards the opening 10a of the compartment 10, thereby improving the rotation efficiency of the top cover 20. Furthermore, during the second half of the closing process, the top cover 20 can be automatically closed without the user applying any force, thus effectively improving the practicality of the wireless microphone charging case 1.

[0215] As shown in Figures 18-20, when the top cover 20 switches from the second state to the first state, during the first half of the opening process (i.e., the process of rotating from the second state to the position of half rotation angle α), the top cover 20 is subjected to a reaction force corresponding to the gradually increasing elastic deformation caused by the compression of the elastic element 33. This reaction force effectively maintains the second state of the top cover 20. During the second half of the opening process (i.e., the process of rotating from the position of half rotation angle α to the first state), the top cover 20 is subjected to a reaction force corresponding to the gradually decreasing elastic deformation caused by the compression of the elastic element 33. This reaction force facilitates the top cover 20 to rotate in a direction away from the opening 10a of the compartment 10, thereby improving the rotation efficiency of the top cover 20. Furthermore, during the second half of the opening process, the top cover 20 can be opened automatically without the user applying any force, thus effectively improving the practicality of the wireless microphone charging case 1.

[0216] As shown in Figure 21, the elastic member 33 includes a first connecting portion 331, a second connecting portion 332, and a third connecting portion 333; the first connecting portion 331 is rotatably connected to the fixed seat 31 as the first end of the elastic member 33; the second connecting portion 332 is rotatably connected to the free end of the rotating seat 32 as the second end of the elastic member 33; the third connecting portion 333 is connected between the first connecting portion 331 and the second connecting portion 332, the third connecting portion 333 bends toward the rotating seat 32, and the third connecting portion 333 is adapted to produce the above-mentioned elastic deformation.

[0217] The first connecting part 331, the second connecting part 332 and the third connecting part 333 can be formed into an integral structure by means of injection molding or 3D printing, but not limited to.

[0218] By designing a first connecting part 331, the first connecting part 331 serves as the first end of the elastic member 33 to realize the connection between the elastic member 33 and the fixed base 31; by designing a second connecting part 332, the second connecting part 332 serves as the second end of the elastic member 33 to realize the connection between the elastic member 33 and the free end of the rotating base 32; by designing a third connecting part 333, the third connecting part 333 is used to generate the above-mentioned elastic deformation during the rotation of the top cover 20. This elastic deformation facilitates both the opening / closing operation of the top cover 20 and the switching of the top cover 20 to the second / first state.

[0219] As shown in Figure 21, the first connecting part 331 includes two opposing L-shaped spring arms 3311 rotatably connected to the fixed base 31; the second connecting part 332 includes a C-shaped spring arm 3321 rotatably connected to the rotating base 32; the third connecting part 333 includes two parallel V-shaped spring arms 3331; the two L-shaped spring arms 3311 and the two V-shaped spring arms 3331 are connected one-to-one to the ends of the fixed base 31, and the ends of the two V-shaped spring arms 3331 away from the fixed base 31 are respectively connected to the two ends of the C-shaped spring arm 3321.

[0220] By designing the first connecting part 331 as an L-shaped elastic arm 3311, the second connecting part 332 as an U-shaped elastic arm 3321, and the third connecting part 333 as a V-shaped elastic arm 3331, the elastic element 33 forms a simple support structure, which facilitates the processing of the elastic element 33 and also saves materials.

[0221] As shown in Figure 17, the wireless microphone charging case 1 also includes a hook structure (not shown in the figure), and the second end of the elastic member 33 is connected to the free end of the rotating base 32 via the hook structure. In this way, the connection between the second end of the elastic member 33 and the free end of the rotating base 32 can be achieved by hooking, thereby facilitating the assembly between the elastic member 33 and the rotating base 32.

[0222] Specifically, the latch structure includes a latch (not shown in the figure) and a latch (not shown in the figure); the latch is disposed on at least one of the second end of the elastic member 33 and the free end of the rotating seat 32; the latch is disposed on at least the other of the second end of the elastic member 33 and the free end of the rotating seat 32; the latch engages with the latch. The latch can be, but is not limited to, integrally formed with the second end of the elastic member 33 and / or the free end of the rotating seat 32 by injection molding or 3D printing; the latch can also be, but is not limited to, formed on the free end of the rotating seat 32 and / or the second end of the elastic member 33 by injection molding or 3D printing. By designing the latch and the latch, the engagement of the latch and the latch achieves the connection between the second end of the elastic member 33 and the free end of the rotating seat 32, thereby realizing the assembly between the elastic member 33 and the rotating seat 32, which is simple to operate.

[0223] As shown in Figure 22, the wireless microphone charging case 1 also includes a first adsorption member 40, which is disposed on the edge of the case body 10 near the opening 10a; the wireless microphone charging case 1 also includes a second adsorption member 50, which is disposed on the free end of the top cover 20 and is correspondingly disposed to the first adsorption member 40; the first adsorption member 40 and the second adsorption member 50 are connected by magnetic adsorption.

[0224] The first adsorption element 40 may include, but is not limited to, at least one of a magnet and a steel sheet; the second adsorption element 50 may also include, but is not limited to, at least one of a magnet and a steel sheet. For example, when the first adsorption element 40 is a magnet and the corresponding second adsorption element 50 is a steel sheet, the magnet of the first adsorption element 40 adsorbs the steel sheet of the second adsorption element 50; as another example, when the first adsorption element 40 is a steel sheet and the corresponding second adsorption element 50 is a magnet, the magnet of the second adsorption element 50 adsorbs the steel sheet of the first adsorption element 40; as yet another example, when the first adsorption element 40 is a magnet and the corresponding second adsorption element 50 is also a magnet, the magnet of the first adsorption element 40 and the magnet of the second adsorption element 50 attract each other.

[0225] By designing the first adsorption element 40 and the second adsorption element 50, a magnetic adsorption force is generated between them. During the latter half of the closing process of the top cover 20, the top cover 20 gradually rotates towards the opening 10a of the compartment 10, causing the second adsorption element 50 to gradually approach the first adsorption element 40 in space. The magnetic adsorption force between the second adsorption element 50 and the first adsorption element 40 can cooperate with the reaction force corresponding to the gradually decreasing elastic deformation caused by the compression of the elastic element 33, further facilitating the rotation of the top cover 20 towards the opening 10a of the compartment 10, thereby further improving the rotation efficiency of the top cover 20. By designing the first adsorption element 40 and the second adsorption element 50, when the top cover 20 is in the aforementioned second state, the magnetic adsorption force generated between the second adsorption element 50 and the first adsorption element 40 allows the top cover 20 to be stably positioned on the compartment 10, thus effectively improving the connection stability between the top cover 20 and the compartment 10 when in the aforementioned second state.

[0226] Specifically, as shown in Figure 22, the first adsorption member 40 includes a first magnet 41 connected to the chamber body 10; the second adsorption member 50 includes a second magnet 51 connected to the top cover 20.

[0227] The number of first magnets 41 can be one or more (two or more); and when there are multiple first magnets 41, the multiple first magnets 41 can be arranged at equal intervals along the edge of the opening 10a of the compartment 10. The specific connection method between the first magnets 41 and the compartment 10 is not limited here; designers can design it reasonably according to actual needs. For example, the first magnets 41 can be detachably connected to the compartment 10 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection; or, for example, the first magnets 41 can be non-detachably connected to the compartment 10 by adhesive bonding.

[0228] The number of second magnets 51 can be one or more (two or more); and when there are multiple second magnets 51, the multiple second magnets 51 can be arranged at intervals at the free end of the top cover 20. The specific connection method between the second magnets 51 and the top cover 20 is not limited here, and the designer can make reasonable designs according to actual needs; for example, the second magnets 51 can be detachably connected to the top cover 20 by at least one of the following methods: screw connection, snap connection, or plug connection; or, for example, the second magnets 51 can be non-detachably connected to the top cover 20 by adhesive bonding.

[0229] By designing the first adsorption element 40 as the first magnet 41 and the second adsorption element 50 as the second magnet 51, during the latter half of the closing process of the top cover 20, the top cover 20 gradually rotates towards the opening 10a of the compartment 10, causing the second magnet 51 to gradually approach the first magnet 41 in space. A magnetic attraction force is generated between the second magnet 51 and the first magnet 41. This magnetic attraction force can cooperate with the reaction force corresponding to the gradually decreasing elastic deformation caused by the compression of the elastic element 33, further facilitating the rotation of the top cover 20 towards the opening 10a of the compartment 10, thereby further improving the rotation efficiency of the top cover 20. By designing the first adsorption element 40 as the first magnet 41 and the second adsorption element 50 as the second magnet 51, when the top cover 20 is in the aforementioned second state, the magnetic attraction force generated between the second magnet 51 and the first magnet 41 allows the top cover 20 to be stably positioned on the compartment 10, thus effectively improving the connection stability between the top cover 20 and the compartment 10 when in the aforementioned second state.

[0230] As shown in Figure 22, the wireless microphone charging case 1 also includes a magnetic sensor 60 and a controller (not shown in the figure) disposed inside the case body 10; the magnetic sensor 60 is used to sense changes in the magnetic field and generate corresponding electrical signals; the controller is electrically connected to the magnetic sensor 60; the wireless microphone charging case 1 also includes a prompting device (not shown in the figure) disposed inside the case body 10; the controller is electrically connected to the prompting device, and the controller controls the prompting device to perform corresponding operations according to the electrical signals.

[0231] Specifically, when the magnetic sensor 60 senses a change in the magnetic field around the first magnet 41, it generates a first electrical signal (one of the aforementioned electrical signals, such as the digital signal "1"). At this time, the controller controls the prompting device to be in a first prompting state according to the first electrical signal. When the magnetic sensor 60 senses no change in the magnetic field around the first magnet 41, it generates a second electrical signal (another of the aforementioned electrical signals, different from the first electrical signal, such as the digital signal "0"). At this time, the controller controls the prompting device to be in a second prompting state according to the second electrical signal.

[0232] The magnetic sensor 60 can be, but is not limited to, a Hall sensor.

[0233] The notification device can be, but is not limited to, a speaker or an indicator light. For example, when the notification device is a speaker, in the first notification state described above, the speaker can broadcast a voice prompt such as "Top cover 20 is closed," and in the second notification state described above, the speaker can broadcast a voice prompt such as "Top cover 20 is open." As another example, when the notification device is an indicator light, in the first notification state described above, the indicator light can display a visual prompt such as "red," and in the second notification state described above, the indicator light can display a visual prompt such as "green."

[0234] By designing a controller, a magnetic field sensor, and a prompter, the controller can control the prompter to perform corresponding operations based on the electrical signal generated by the change in magnetic field sensed by the magnetic field sensor. The user can then determine the current state of the top cover 20 based on the prompter, which greatly improves the convenience of use.

[0235] As shown in Figure 22, the wireless microphone charging case 1 also includes a magnetic conductor 70 disposed in the case body 10. One end of the magnetic conductor 70 extends to one side of the first magnet 41, and the other end of the magnetic conductor 70 extends to one side of the magnetic sensor 60.

[0236] The specific material used to manufacture the magnetic conductive component 70 can be, but is not limited to, one of ferrite, cobalt-iron alloy, nickel-iron alloy, and ferrite. The specific structure of the magnetic conductive component 70 is not limited here; designers can design it appropriately according to actual needs. For example, the magnetic conductive component 70 can be, but is not limited to, a columnar structure, a block structure, or a sheet structure.

[0237] By designing the magnetic conductive element 70, the magnetic conductive element 70 can conduct the magnetism of the first magnet 41 and the magnetism of the second magnet 51 corresponding to the first magnet 41 to the magnetic sensor 60, so that the magnetic sensor 60 can effectively sense the change in magnetic field and generate the corresponding electrical signal.

[0238] It should be noted that the wireless microphone charging case 1 also includes a charging PCB board. There is a set of charging PCB boards, which are located below the microphone mounting position 10b. The magnetic sensor 60 can be mounted on the charging PCB board. After being extended by the magnetic guide 70, the magnetism of the first magnet 41 located on the edge of the case 10 near the opening 10a, and the magnetism of the second magnet 51 corresponding to the first magnet 41, can be extended by the magnetic guide 70 and cover the magnetic sensor 60. There is no need to add a separate circuit board for the magnetic sensor 60 for installation and connection, which can reduce the number of circuit boards and optimize space.

[0239] Referring to Figure 13, in a second aspect, this application proposes a wireless microphone charging system, which includes a wireless microphone 2 and the aforementioned wireless microphone charging compartment 1; the compartment 10 has a microphone mounting position 10b; the wireless microphone 2 is mounted on the compartment 10 corresponding to the microphone mounting position 10b.

[0240] Based on the wireless microphone charging system in this application embodiment, the wireless microphone charging case 1 described above has an elastic member 33 that can provide effective support for the top cover 20 when the top cover 20 is in the first state, so that the top cover 20 can be maintained in the first state, thereby effectively improving the convenience of user use.

[0241] Third Embodiment

[0242] Please refer to Figures 23-26. This application proposes a wireless microphone charging system 1, in which the components are arranged more compactly in the spatial structure, thereby achieving structural optimization and effectively reducing the overall volume of the wireless microphone charging system 1.

[0243] The wireless microphone charging system 1 includes a housing 10, a charging base 20, a support base 30, and a power supply 40. The housing 10 defines a top-opening receiving cavity 11a. The charging base 20 is at least partially disposed within the receiving cavity 11a, and has a first charging slot 21 and a second charging slot 22 with their openings facing the opening of the receiving cavity 11a and arranged in a predetermined direction OO'. The first charging slot 21 is used to accommodate one of a transmitter 91 and a receiver 92 of different sizes, and the second charging slot 22 is used to accommodate the other of the transmitter 91 and receiver 92. The bottom wall of the first charging slot 21 is further away from the opening of the receiving cavity 11a than the bottom wall of the second charging slot 22. The support base 30 is disposed within the receiving cavity 11a and at least partially located below the second charging slot 22. The support base 30 and the charging base 20 together form a mounting cavity 30a. The power supply 40 is disposed within the mounting cavity 30a.

[0244] The specific structure of the wireless microphone charging system 1 will be described in detail below with reference to Figures 23-29.

[0245] As shown in Figures 23-26, the wireless microphone charging system 1 includes a housing 10, a charging base 20, a support base 30, and a power supply 40.

[0246] The housing 10 serves as the shell of the wireless microphone charging system 1. The specific shape of the housing 10 is not limited here; designers can design it appropriately according to actual needs. For example, the outer contour of the housing 10 can be, but is not limited to, a cuboid or cylinder-like shape. The specific material used to manufacture the housing 10 is also not limited here; designers can choose appropriately according to actual needs. For example, the material used to manufacture the housing 10 can be, but is not limited to, plastic or PVC. This ensures that the raw materials are widely available and easily accessible, and effectively reduces the cost of the wireless microphone charging system 1.

[0247] The chamber 10 defines a top-open receiving cavity 11a.

[0248] The charging stand 20 serves as a support for the transmitter 91 and receiver 92 in the wireless microphone charging system 1. The specific materials used to manufacture the charging stand 20 are not limited here; designers can choose according to actual needs. For example, the charging stand 20 can be made of, but is not limited to, plastic or PVC. This allows for a wide range of readily available raw materials and effectively reduces the cost of the wireless microphone charging system 1.

[0249] The charging base is at least partially located within the receiving cavity 11a of the compartment 10. The charging base 20 may or may not be connected to the compartment 10; for example, when the charging base 20 is connected to the compartment 10, the charging base 20 may be detachably connected to the compartment 10 by at least one of the following methods, including but not limited to screwing, snap-fitting, or plugging; the charging base 20 may also be non-detachably connected to the compartment 10 by riveting or gluing; as another example, when the charging base is not connected to the compartment 10, the charging base 20 may be connected to the support base 30.

[0250] The charging dock 20 has a first charging slot 21 and a second charging slot 22; the first charging slot 21 is used to accommodate one of a transmitter 91 and a receiver 92 of different sizes; the second charging slot 22 is used to accommodate the other of the transmitter 91 and the receiver 92. For example, when the first charging slot 21 is used to accommodate the transmitter 91, the corresponding second charging slot 22 is used to accommodate the receiver 92; as another example, when the first charging slot 21 is used to accommodate the receiver 92, the corresponding second charging slot 22 is used to accommodate the transmitter 91.

[0251] The openings of the first charging slot 21 and the second charging slot 22 are both oriented towards the opening of the receiving cavity 11a of the housing 10; the first charging slot 21 and the second charging slot 22 are arranged along a preset direction OO'. For example, when the outer contour of the housing 10 is roughly cuboid, and the first charging slot 21 is used to house the transmitter 91 and the second charging slot 22 is used to house the receiver 92, the number of first charging slots 21 can be one, and the number of second charging slots 22 can be two. In this case, one first charging slot 21 and two second charging slots 22 are arranged along the length direction of the housing 10 (one of the aforementioned preset directions OO'). As another example, when the outer contour of the housing 10 is roughly cuboid, and the first charging slot 21 is used to house the receiver 92 and the second charging slot 22 is used to house the transmitter 91, the number of first charging slots 21 can be two, and the number of second charging slots 22 can be one. In this case, two first charging slots 21 and one second charging slot 22 are arranged along the length direction of the housing 10.

[0252] It is understandable that the first charging slot 21 and the second charging slot 22 on the charging base 20 are typically formed by mold injection molding or 3D printing, so that the shape of the first charging slot 21 matches the shape of one of the corresponding transmitter 91 and receiver 92, and the shape of the second charging slot 22 matches the shape of the other of the corresponding transmitter 91 and receiver 92. The first charging slot 21 / second charging slot 22 is formed by the bottom wall and the side wall of the slot. It should be noted that the "bottom wall / side wall" here refers to the three-dimensional solid part corresponding to the wall thickness of the first charging slot 21 / second charging slot 22, and not to the two-dimensional surface corresponding to the "bottom surface / side surface" of the first charging slot 21 / second charging slot 22.

[0253] The bottom wall of the first charging slot 21 is further away from the opening of the receiving cavity 11a of the housing 10 than the bottom wall of the second charging slot 22; that is, the depth of the first charging slot 21 is greater than the depth of the second charging slot 22. Thus, the first charging slot 21 can be used, but is not limited to, to accommodate a receiver 92 with integrated adjustment function (on the one hand, a corresponding adjustment knob needs to be set, and on the other hand, the circuit board is relatively large, resulting in the overall volume of the receiver 92 being larger than the overall volume of the transmitter 91).

[0254] As shown in Figures 23-26, the support base 30 serves as another bracket for the wireless microphone charging system 1, supporting the power supply 40. The specific material used to manufacture the support base 30 is not limited here; designers can choose according to actual needs. For example, the material used to manufacture the support base 30 can be, but is not limited to, plastic or PVC. This ensures that the raw materials are widely available and easily accessible, effectively reducing the cost of the wireless microphone charging system 1. It should be noted that the materials used to manufacture the support base 30, charging base 20, and housing 10 can be the same or different.

[0255] The support base 30 is disposed within the receiving cavity 11a. The support base 30 may or may not be connected to the housing 10; for example, when the support base 30 is connected to the housing 10, the support base 30 may be detachably connected to the housing 10 by at least one of the following methods, including but not limited to screwing, snap-fitting, or plugging; the support base 30 may also be non-detachably connected to the housing 10 by riveting or adhesive bonding. Alternatively, when the support base 30 is not connected to the housing 10, it may be connected to the charging base 20. It should be noted that when neither the support base 30 nor the charging base 20 is connected to the housing 10, the wireless microphone charging system 1 further includes a connecting bracket, through which at least one of the support base 30 and the charging base 20 is connected to the housing 10.

[0256] The power supply 40 serves as the power transmission component of the wireless microphone charging system 1. On the one hand, it can supply power to the transmitter 91 and the receiver 92, and on the other hand, it can receive power from an external power source 40 (such as a power bank or 220V AC mains power). The power supply 40 may include, but is not limited to, a battery.

[0257] The support base 30 is at least partially located below the second charging slot 22, and the support base 30 and the charging base 20 together form a mounting cavity 30a for accommodating the power supply 40. The power supply 40 and the support base 30 may or may not be connected; for example, when there is a connection between the power supply 40 and the support base 30, the power supply 40 may be detachably connected to the support base 30 by means of snap-fit ​​or plug-in, or the power supply 40 may be non-detachably connected to the support base 30 by means of adhesive bonding; as another example, when there is no connection between the power supply 40 and the support base 30, the power supply 40 can be clamped and fixed between the support base 30 and the first circuit board 50 (described below).

[0258] Based on the wireless microphone charging system 1 in this embodiment, the charging base 20 adjusts the size of the corresponding charging slots according to the size difference between the transmitter 91 and the receiver 92, so that the first charging slot 21 is suitable for accommodating one of the transmitter 91 and receiver 92 of different sizes, and the second charging slot 22 is suitable for accommodating the other of the transmitter 91 and receiver 92. By designing the bottom wall of the first charging slot 21 to be further away from the opening of the receiving cavity 11a of the housing 10 than the bottom wall of the second charging slot 22, there is a height difference between the bottom walls of the first charging slot 21 and the second charging slot 22 in the direction perpendicular to the plane where the opening of the receiving cavity 11a of the housing 10 is located. The support base 30 located below the second charging slot 22 can make full use of this height difference to form a mounting cavity 30a for accommodating the power supply 40 together with the charging base 20. In this way, the components of the wireless microphone charging system 1 are arranged more compactly in the spatial structure, achieving structural optimization and effectively reducing the overall volume of the wireless microphone charging system 1.

[0259] As shown in Figure 26, the two ends of the support base 30 along the preset direction OO' are respectively connected to the charging base 20 to form an installation cavity 30a together with the charging base 20. The specific connection method between the support base 30 and the charging base 20 is not limited here; designers can design it reasonably according to actual needs. For example, the support base 30 can be detachably connected to the charging base 20 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. In this design, by connecting the two ends of the support base 30 along the preset direction OO' to the charging base 20, the assembly difficulty between the support base 30 and the charging base 20 is reduced.

[0260] As shown in Figures 26-28, the support base 30 includes a base plate 31 and an upright plate 32; the first end of the base plate 31 is connected to the charging base 20; the upright plate 32 is connected to the second end of the base plate 31 and is also connected to the charging base 20; the first end and the second end are the two ends of the base plate 31 that are arranged opposite to each other along a preset direction OO'.

[0261] The upright plate 32 and the base plate 31 can be either separate or integrated structures. For example, when the upright plate 32 and the base plate 31 are separate structures, the upright plate 32 can be fixedly connected to the base plate 31 by means of screwing, snap-fitting, plugging, or riveting, but not limited to this. Conversely, when the upright plate 32 and the base plate 31 are integrated structures, the upright plate 32 can be integrally formed with the base plate 31 by means of injection molding or 3D printing, but not limited to this. The first end of the base plate 31 can be detachably connected to the charging base 20 by means of at least one of screwing, snap-fitting, or plugging, but not limited to this. The upright plate 32 can be detachably connected to the charging base 20 by means of at least one of screwing, snap-fitting, or plugging, but not limited to this. For example, in this embodiment, the first end of the base plate 31 is provided with a threaded hole, and the first end of the base plate 31 is connected to the charging base 20 by screwing; the upright plate 32 is also provided with a threaded hole, and the upright plate 32 is connected to the charging base 20 by screwing.

[0262] By designing the base plate 31 and the upright plate 32, the support base 30 is made into an L-shaped structure. This, together with the L-shaped charging base, allows the support base 30 and the charging base 20 to jointly enclose a rectangular mounting cavity 30a for accommodating the power supply 40. The structure is simple and easy to implement.

[0263] As shown in Figures 26-28, the wireless microphone charging system 1 also includes a first circuit board 50; the first circuit board 50 is electrically connected to the power supply 40, and the first circuit board 50 is at least partially located on the side of the power supply 40 facing the cavity 11a of the housing 10. The charging terminal 51 of the first circuit board 50 passes through the bottom wall of the second charging slot 22 for electrical connection with the charging port of one of the transmitter 91 and the receiver 92. One end of the first circuit board 50 in the preset direction OO' is connected to the charging base 20, and the other end of the first circuit board 50 in the preset direction OO' overlaps with the end of the upright plate 32 near the cavity 11a of the housing 10.

[0264] In this embodiment, one end of the first circuit board 50 in the preset direction OO' can be detachably connected to the charging base 20 by at least one of the following methods: screwing, snap-fitting, or plugging. For example, in this embodiment, one end of the first circuit board 50 in the preset direction OO' is connected to the charging base 20 by screws, and the other end of the first circuit board 50 in the preset direction OO' is located between the upright plate 32 and the charging base 20, and the upright plate 32 is connected to the charging base 20 by screws to clamp and fix the edge of the first circuit board 50.

[0265] By designing the first circuit board 50 to be electrically connected to the power supply 40, the power supply 40 can charge one of the transmitter 91 and receiver 92 housed in the second charging slot 22 through the charging terminal 51 of the first circuit board 50. By designing one end of the first circuit board 50 in the preset direction OO' to be connected to the charging base 20 and the other end of the first circuit board 50 in the preset direction OO' to overlap with the top plate, the assembly difficulty between the first circuit board 50 and the charging base 20, and between the first circuit board 50 and the support base 30, can be effectively reduced.

[0266] As shown in Figures 25, 27, and 28, the storage body 10 includes a storage body 11 and a first positioning part 12; the storage body 11 has the aforementioned receiving cavity 11a; the first positioning part 12 is disposed on the inner side of the storage body 11. The support base 30 also includes a second positioning part 33; the second positioning part 33 is disposed on the side of the upright plate 32 facing the inner side of the storage body 11, and the second positioning part 33 cooperates with the first positioning part 12 to position the support base 30 on the storage body 10.

[0267] The first positioning part 12 can be a solid structure, such as a positioning rib, formed on the inner side of the storage body 11. The corresponding second positioning part 33 is a virtual structure, such as a positioning groove, formed on the inner side of the upright plate 32 facing the storage body 11. In this case, the positioning rib is embedded in the positioning groove to achieve relative fixation between the support base 30 and the storage body 10. Alternatively, the first positioning part 12 can be a virtual structure, such as a positioning groove, formed on the inner side of the storage body 11. The corresponding second positioning part 33 is a solid structure, such as a positioning rib, formed on the inner side of the upright plate 32 facing the storage body 11. In this case, the positioning rib is embedded in the positioning groove to achieve relative fixation between the support base 30 and the storage body 10. The first positioning part 12 can be integrally formed with the storage body 11 by injection molding or 3D printing, but is not limited to this method. The second positioning part 33 can be integrally formed with the upright plate 32 by injection molding or 3D printing, but is not limited to this method.

[0268] By designing a first positioning part 12 and a second positioning part 33, the first positioning part 12 and the second positioning part 33 cooperate to fix the support base 30 to the compartment body 10, thereby further enhancing the connection stability of the support base 30.

[0269] As shown in Figures 26-28, the support base 30 also includes a heat dissipation section 34, which is disposed on the base plate 31. The heat dissipation section 34 can be, but is not limited to, a solid structure such as heat dissipation fins disposed on the base plate 31, or it can be, but is not limited to, a virtual structure such as heat dissipation holes or heat dissipation grooves formed on the base plate 31. The heat dissipation section 34 can be integrally formed with the base plate 31 by injection molding or 3D printing, but is not limited to that performed by injection molding or 3D printing. For example, in this embodiment, the heat dissipation section 34 is a heat dissipation groove disposed on the bottom surface of the base plate 31. By designing the heat dissipation section 34 on the base plate 31, the heat dissipation section 34 can promptly conduct away the heat generated by the power supply 40 during operation, preventing heat accumulation.

[0270] As shown in Figures 26-28, the support base 30 also includes an overlapping portion 35; the overlapping portion 35 is disposed on the side of the base plate 31 facing away from the cavity opening 11a of the housing 10. The wireless microphone charging system 1 also includes a second circuit board 60; the second circuit board 60 is electrically connected to the power supply 40, the second circuit board 60 is located below the first charging slot 21, the charging terminal 61 of the second circuit board 60 passes through the bottom wall of the first charging slot 21 for electrical connection with the charging port of the other of the transmitter 91 and receiver 92, one end of the second circuit board 60 in the preset direction OO' is connected to the charging base 20, and the other end of the second circuit board 60 in the preset direction OO' is connected to the overlapping portion 35.

[0271] The overlapping portion 35 may be, but is not limited to, a solid structure such as a hook, located on the side of the base plate 31 opposite to the opening of the receiving cavity 11a of the compartment 10. Alternatively, the overlapping portion 35 may be, but is not limited to, a virtual structure such as a slot, formed on the side of the base plate 31 opposite to the opening of the receiving cavity 11a of the compartment 10. The overlapping portion 35 may be integrally formed with the base plate 31 by injection molding or 3D printing, but is not limited to this method.

[0272] One end of the second circuit board 60 in the preset direction OO' can be detachably connected to the charging base 20 by at least one of the following methods: screwing, snap-fitting, or plugging. For example, in this embodiment, one end of the second circuit board 60 in the preset direction OO' is connected to the charging base 20 by screwing.

[0273] By designing a second circuit board 60, which is electrically connected to a power supply 40, the power supply 40 can charge the other of the transmitter 91 and receiver 92 housed in the first charging slot 21 through the charging terminal 61 of the second circuit board 60. By designing one end of the second circuit board 60 in the preset direction OO' to connect to the charging base 20 and the other end of the second circuit board 60 in the preset direction OO' to overlap with the overlapping part 35, the assembly difficulty between the second circuit board 60 and the charging base 20, and between the second circuit board 60 and the support base 30, can be effectively reduced. It is worth mentioning that the first circuit board 50 is used to control the charging output of one of the transmitter 91 and receiver 92 housed in the second charging slot 22, and the second circuit board 60 is used to control the charging output of the other of the transmitter 91 and receiver 92 housed in the first charging slot 21. The first circuit board 50 and the second circuit board 60 are arranged in layers, which not only achieves reasonable space optimization but also ensures smooth component charging output.

[0274] As shown in Figures 26-28, the support base 30 also includes a clearance portion 36. The clearance portion 36 is disposed on the side of the base plate 31 facing away from the opening of the receiving cavity 11a of the compartment 10, and is used to avoid electronic components mounted on the second circuit board 60. The clearance portion 36 may be, but is not limited to, a clearance groove or clearance hole forming on the side of the base plate 31 facing away from the opening of the receiving cavity 11a of the compartment 10. By designing the clearance portion 36 on the base plate 31, the clearance portion 36 can effectively avoid electronic components on the second circuit board 60, making reasonable use of the internal space of the base plate 31, and making the second circuit board 60 and the support base 30 more compact in spatial arrangement, thereby further reducing the overall size of the wireless microphone charging system 1.

[0275] As shown in Figure 29, the first charging slot 21 is used to house the receiver 92, and the second charging slot 22 is used to house the transmitter 91. When the receiver 92 is installed in the first charging slot 21 and the transmitter 91 is installed in the second charging slot 22, the highest point of the receiver 92 and the highest point of the transmitter 91 are on the same horizontal line. This method of storing the receiver 92 and transmitter 91 at the same height helps to reduce the obstruction of the line of sight caused by the height difference, making it easier for users to quickly identify and conveniently retrieve the desired components.

[0276] As shown in Figure 7, the wireless microphone charging system 1 also includes an insulating buffer 70, which is disposed between the power supply 40 and the support base 30. The insulating buffer 70 can be, but is not limited to, an insulating buffer pad or an insulating buffer block. The specific material used to manufacture the insulating buffer 70 can be, but is not limited to, EVA (Ethylene Vinyl Acetate Copolyme). By designing the insulating buffer 70, it can provide good buffering protection for the power supply 40.

[0277] As shown in Figures 23-25, the wireless microphone charging system 1 also includes a top cover 80, which is rotatably connected to the housing 10 to cover or open the cavity 11a of the housing 10.

[0278] Fourth embodiment

[0279] The wireless microphone charging system includes a transmitter, a receiver, and a wireless microphone charging case; the transmitter is used to pick up sound; the receiver is used to connect to the user terminal and transmit audio signals to the user terminal; the wireless microphone charging case is equipped with a charging slot, in which the transmitter and receiver are installed.

[0280] In wireless microphone charging cases, indicator lights are needed to display remaining battery power. When the indicator lights are on, due to the direct connection between adjacent light guide pillars in the relevant technology, the light projected by the indicator light crosses into the light output ports of adjacent indicator lights, creating a light crosstalk phenomenon. This prevents users from accurately reading the battery level. Therefore, effectively improving the light crosstalk phenomenon of indicator lights has become an urgent problem to be solved.

[0281] To address the aforementioned issues, please refer to Figure 30. This application proposes a wireless microphone charging system 1, which includes a transmitter 10, a receiver 20, and a wireless microphone charging case 30.

[0282] Transmitter 10 is used for sound reception; the specific structure of transmitter 10 is not limited here, and designers can make reasonable designs according to actual needs.

[0283] The receiver 20 is used to connect to the user terminal and transmit audio signals to the user terminal; the specific structure of the receiver 20 is not limited here, and the designer can make a reasonable design according to the actual needs.

[0284] The wireless microphone charging case 30 serves as the charging box for the wireless microphone charging system 1. It is used to charge the transmitter 10 and receiver 20 on one hand, and to store the transmitter 10 and receiver 20 on the other.

[0285] As shown in Figures 30-32, the wireless microphone charging case 30 includes a case body 31, a charging base 32, and an indicator light 33.

[0286] The housing 31 serves as the shell of the wireless microphone charging case 30. The specific shape of the housing 31 is not limited here; designers can design it appropriately according to actual needs. For example, the outer contour of the housing 31 can be, but is not limited to, a cuboid or cylindrical shape. The specific material used to manufacture the housing 31 is also not limited here; designers can choose appropriately according to actual needs. For example, the material used to manufacture the housing 31 can be, but is not limited to, plastic or PVC. This ensures that the raw materials are widely available and easily accessible, effectively reducing the cost of the wireless microphone charging case 30.

[0287] The compartment 31 defines a top-open receiving cavity 311; the receiving cavity 311 is the space within the compartment 31 that can be used, but is not limited to, for accommodating components such as the charging base 32.

[0288] The charging stand 32 serves as a support for the wireless microphone charging case 30, supporting the transmitter 10 and receiver 20. The specific materials used to manufacture the charging stand 32 are not limited here; designers can choose appropriately based on actual needs. For example, the charging stand 32 can be made of, but is not limited to, plastic or PVC. This allows for a wide range of readily available raw materials and effectively reduces the cost of the wireless microphone charging case 30.

[0289] The charging base 32 is at least partially located within the receiving cavity 311 of the housing 31. The specific connection method between the charging base 32 and the housing 31 is not limited here; designers can design it reasonably according to actual needs. For example, the charging base 32 can be detachably connected to the housing 31 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the charging base 32 can be non-detachably connected to the housing 31 by riveting or adhesive bonding, but not limited to this method.

[0290] The charging base 32 has a charging slot 321 with its opening facing the cavity 311 of the housing 31; the charging slot 321 is used to accommodate the transmitter 10 and the receiver 20. For example, the charging slot 321 includes a first charging slot 321 and a second charging slot 321, the first charging slot 321 is used to accommodate the transmitter 10 and the second charging slot 321 is used to accommodate the receiver 20.

[0291] Indicator light 33 serves as a power indicator for the wireless microphone charging case 30. Users can determine the power level of at least one of the following based on the display of indicator light 33: transmitter 10, receiver 20, and power source 38 (which acts as a power transmission component for the wireless microphone charging case 30, supplying power to transmitter 10 and receiver 20, and receiving power from an external power source 38 (e.g., a power bank or 220V AC mains)). For example, indicator light 33 can be used to display the power level of transmitter 10 alone; or receiver 20 alone; or power source 38 alone; and so on. Further details are omitted here. It should be noted that, for transmitter 10 and receiver 20, the power level displayed by indicator light 33 can be either the remaining power of transmitter 10 and / or receiver 20, or the charging level of transmitter 10 and / or receiver 20. For example, when transmitter 10 and receiver 20 are in use, the user can determine the current remaining power of transmitter 10 and / or receiver 20 based on the display of indicator light 33; similarly, when transmitter 10 and receiver 20 are charging, the user can determine the current charging level of transmitter 10 and / or receiver 20 based on the display of indicator light 33. Similarly, for power supply 38, the power level displayed by indicator light 33 can be either the charging level of power supply 38, or the remaining power of power supply 38. For example, when power supply 38 is charging, the user can determine the current charging level of power supply 38 based on the display of indicator light 33; similarly, when power supply 38 is discharging, the user can determine the current remaining power of power supply 38 based on the display of indicator light 33.

[0292] The number of indicator lights 33 can be multiple groups; for example, there can be two, three, four, five, six, or more groups of indicator lights 33. It should be noted that each group of indicator lights 33 includes at least one LED; and the number of LEDs in multiple groups of indicator lights 33 can be the same or different. The LEDs have different display states such as constantly on, constantly off, and flashing. Users can determine the power level of at least one of the transmitter 10, receiver 20, and power supply 38 based on the arrangement of the different display states of the LEDs in the multiple groups of indicator lights 33. Of course, the LEDs can also change their state by changing their color.

[0293] The user can determine the power level of at least one of the transmitter 10, receiver 20, and power supply 38 by observing the different colors of the LEDs in the multiple indicator lights 33.

[0294] The sidewall of the compartment 31 is provided with multiple sets of mounting positions 312 that communicate with the receiving cavity 311 and are arranged along a first preset direction MM'. For example, the number of mounting positions 312 can be two, three, four, five, six or more. It should be noted that each set of mounting positions 312 includes at least one mounting hole; and the number of mounting holes in multiple sets of mounting positions 312 can be the same or different. It should also be noted that when the outer contour of the compartment 31 is cuboid, the multiple sets of mounting positions 312 can be arranged along the length direction of the compartment 31 (one of the aforementioned first preset directions MM').

[0295] As shown in Figures 31-33, the wireless microphone charging case 30 also includes an indicator light guide structure 34; the indicator light guide structure 34 is a structural component used to transmit the light projected by the indicator light 33 from the indicator light 33 to another point at a certain distance from the indicator light 33 with minimal loss; the indicator light guide structure 34 includes a connector 341, a mounting body 342 and a light guide unit 343.

[0296] The connector 341 serves as the base of the indicator light guide structure 34. The specific structure of the connector 341 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the connector 341 can be, but is not limited to, a plate-like structure or a frame structure.

[0297] The connecting seat 341 is at least partially located within the receiving cavity 311 of the compartment 31; for example, the connecting seat 341 may be partially located within the receiving cavity 311 of the compartment 31, with the remaining portion extending out of the receiving cavity 311 of the compartment 31 via the bottom wall of the compartment 31; or, for example, the connecting seat 341 may be entirely located within the receiving cavity 311 of the compartment 31.

[0298] The connector 341 is used to connect to the container body 31. The specific connection method between the connector 341 and the container body 31 is not limited here, and the designer can make a reasonable design according to the actual needs; for example, the connector 341 can be detachably connected to the container body 31 by at least one of the following methods: screw connection, snap connection or plug connection; or, for example, the connector 341 can also be non-detachably connected to the container body 31 by adhesive bonding or riveting.

[0299] Mounting body 342 serves as the carrier of indicator light guide structure 34 to support light guide unit 343; the specific structure of mounting body 342 is not limited here, and designers can make reasonable designs according to actual needs; for example, mounting body 342 can be, but is not limited to, columnar structure, strip structure or block structure.

[0300] The mounting body 342 is located inside the receiving cavity 311 of the compartment 31, and the mounting body 342 is connected to the connecting seat 341. The specific connection method between the mounting body 342 and the connecting seat 341 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the mounting body 342 can be integrally formed with the connecting seat 341 by injection molding or 3D printing, but not limited to this method.

[0301] The number of mounting bodies 342 is multiple; for example, the number of mounting bodies 342 can be two, three, four, five, six or more. The multiple mounting bodies 342 are arranged at intervals along a first preset direction MM', that is, a gap is formed between two adjacent mounting bodies 342.

[0302] Multiple mounting bodies 342 are configured in a one-to-one correspondence with multiple sets of indicator lights 33, that is, each set of indicator lights 33 corresponds to one mounting body 342.

[0303] The light guide unit 343 serves as the light guide component of the indicator light guide structure 34. The specific structure of the light guide unit 343 is not limited here, and designers can make reasonable designs according to actual needs. For example, the light guide unit can be, but is not limited to, a columnar structure or a block structure.

[0304] The number of light guide units 343 can be multiple sets; for example, the number of light guide units 343 can be two, three, four, five, six or more sets. Multiple sets of light guide units 343 are connected one-to-one with multiple mounting bodies 342, that is, each mounting body 342 is connected to one set of light guide units 343. The specific connection method between the light guide units 343 and the mounting bodies 342 is not limited here; designers can design it reasonably according to actual needs. For example, the light guide units 343 can be integrally formed with the mounting bodies 342 by injection molding or 3D printing, but not limited to this method.

[0305] Each set of light guide units 343 is set to correspond to a set of mounting positions 312; in this way, the light projected by each set of indicator lights 33 is first guided to the corresponding mounting body 342, then guided from the corresponding mounting body 342 to the corresponding light guide unit 343, and finally passes through the corresponding mounting position 312 to be obtained by the user's eyes.

[0306] By designing multiple independent mounting bodies 342 and connecting multiple sets of light guide units 343 one-to-one to the mounting bodies 342, different mounting bodies 342 can guide the light projected by different indicator lights 33 to the corresponding light guide units 343. Furthermore, the gap between two adjacent mounting bodies 342 can effectively block the light projected by two adjacent indicator lights 33, thus effectively improving the problem of light crosstalk between adjacent indicator lights 33. By designing a connecting base 341, which connects to multiple mounting bodies 342, an integrated design of multiple sets of light guide units 343 is achieved. This eliminates the need for multiple individual light guide unit 343 components for light guiding, offering advantages such as saving component costs and facilitating assembly.

[0307] As shown in Figures 33 and 34, the mounting body 342 includes a mounting post 342a extending along a second preset direction NN'; the second preset direction NN' intersects with a first preset direction MM'. The connecting seat 341 includes a base 341a; the base 341a is at least partially located within the receiving cavity 311 of the compartment 31 and connected to the bottom end of the mounting post 342a, and the base 341a is used for detachable connection with the bottom wall of the compartment 31. By designing the base 341a to be detachably connected to the bottom wall of the compartment 31, a detachable connection between the indicator light guide structure 34 and the bottom wall of the compartment 31 can be achieved. This is beneficial to improving the assembly and disassembly efficiency of the indicator light guide structure 34. When dust accumulation on the indicator light guide structure 34 affects the light guiding effect, convenient disassembly and replacement of the indicator light guide structure 34 can be achieved.

[0308] When the outer contour of the compartment 31 is cuboid, the mounting body 342 may include a mounting column 342a extending along the height direction of the compartment 31 (one of the above-mentioned second preset directions NN').

[0309] The base 341a serves as one of the bases of the connecting seat 341. The number of bases 341a can be one or more (two or more). The specific structure of the base 341a is not limited here; designers can design it reasonably according to actual needs. For example, when there is only one base 341a, it can be a long, strip-shaped plate structure, and this base 341a connects to the bottom ends of all mounting columns 342a. The specific detachable connection method between the base 341a and the bottom wall of the compartment 31 is not limited here; designers can design it reasonably according to actual needs. For example, when the base 341a is detachably connected to the bottom wall of the compartment 31 by screws, the base 341a has a countersunk hole, and the bottom wall of the compartment 31 has a threaded hole corresponding to the countersunk hole. The screw passes through the countersunk hole and connects to the threaded hole to position the base 341a on the bottom wall of the compartment 31. Another example is when the base... When base 341a is detachably connected to the bottom wall of compartment 31 by a snap-fit, base 341a has a slot and the bottom wall of compartment 31 has a locking block. The locking block engages with the slot to position base 341a on the bottom wall of compartment 31. Alternatively, when base 341a is detachably connected to the bottom wall of compartment 31 by a plug-in, base 341a has a socket and the bottom wall of compartment 31 has a pin. The pin engages with the socket to position base 341a on the bottom wall of compartment 31.

[0310] As shown in Figures 33 and 34, the connecting seat 341 also includes a top seat 341b. The top seat 341b is at least partially located within the receiving cavity 311 and connected to the top of the mounting post 342a. The top seat 341b is used for a detachable connection with the side wall of the housing 31. By designing the top seat 341b to be detachably connected to the side wall of the housing 31, a detachable connection between the indicator light guide structure 34 and the side wall of the housing 31 can be achieved. This is beneficial to improving the assembly and disassembly efficiency of the indicator light guide structure 34. When dust accumulation on the indicator light guide structure 34 affects the light guiding effect, the indicator light guide structure 34 can be easily disassembled and replaced. It is worth mentioning that the base 341a is detachably connected to the bottom wall of the housing 31, and the top seat 341b is detachably connected to the side wall of the housing 31. This fixes the indicator light guide structure 34 to the bottom and side walls of the housing 31, which can effectively improve the connection stability between the indicator light guide structure 34 and the housing 31.

[0311] The top seat 341b serves as another base for the connecting seat 341. The number of top seats 341b can be one or more (two or more). The specific structure of the top seat 341b is not limited here; designers can design it reasonably according to actual needs. For example, when there is only one top seat 341b, it can be a long strip structure, connecting to the top of all mounting columns 342a. The specific detachable connection method between the top seat 341b and the side wall of the hopper 31 is not limited here; designers can design it reasonably according to actual needs. For example, when the top seat 341b is detachably connected to the side wall of the hopper 31 by screws, the top seat 341b has a countersunk hole, and the side wall of the hopper 31 has a threaded hole corresponding to the countersunk hole. The screw passes through the countersunk hole and connects to the threaded hole to position the top seat 341b on the side wall of the hopper 31. Another example is when the top seat... When the top seat 341b is detachably connected to the side wall of the compartment 31 by a snap-fit, the top seat 341b is provided with a slot, and the side wall of the compartment 31 is provided with a locking block. The locking block engages with the slot to position the top seat 341b on the side wall of the compartment 31. Alternatively, when the top seat 341b is detachably connected to the side wall of the compartment 31 by a plug-in, the top seat 341b is provided with a plug hole, and the side wall of the compartment 31 is provided with a pin. The pin engages with the plug hole to position the top seat 341b on the side wall of the compartment 31.

[0312] It is understandable that the number of bases 341a and top mounts 341b can be one or more. Regardless of the specific number of bases 341a and top mounts 341b, as long as the bases 341a and top mounts 341b can connect multiple mounting posts 342a into one unit, it is acceptable. As shown in Figure 4, there are two bases 341a and one top mount 341b; the two bases 341a are connected to the bottom ends of the two outermost mounting posts 342a one by one; the top mount 341b is connected to the top ends of all mounting posts 342a. In this way, the two bases 341a and one top mount 341b connect multiple mounting posts 342a into one unit, realizing the integrated design of multiple light guide units 343. It eliminates the need to set up multiple individual light guide unit 343 parts to achieve light guiding, which has the advantages of saving parts costs and facilitating assembly.

[0313] As shown in Figure 33, the light guide unit 343 includes a light guide post 343a; the light guide post 343a is located at the center of the mounting post 342a. It should be noted that for each group of light guide units 343, the number of light guide posts 343a in each group of light guide units 343 can be one or more; and the number of light guide posts 343a in multiple groups of light guide units 343 can be the same or different. The light guide posts 343a in each group of light guide units 343 are inserted into the mounting holes of the corresponding mounting positions 312.

[0314] Other designs for the connector 341, the mounting body 342, and the light guide unit 343 may include, but are not limited to, one or more of the following embodiments.

[0315] In the first embodiment, the connector 341, the mounting body 342, and the light guide unit 343 are integrally formed. For example, the connector 341, the mounting body 342, and the light guide unit 343 can be formed into an integral structure by injection molding or 3D printing, but are not limited to this method. This effectively reduces the overall processing difficulty of the indicator light guide structure 34.

[0316] In the second embodiment, at least one of the connector 341, the mounting body 342, and the light guide unit 343 is made of one of acrylic resin, polycarbonate, epoxy resin, and glass. This gives the indicator light guide structure 34 good overall light guiding properties.

[0317] As shown in Figures 31-32, the wireless microphone charging case 30 also includes a circuit board 35; the circuit board 35 is disposed within the receiving cavity 311 of the case body 31. The circuit board 35 serves as an electrical connector for the wireless microphone charging case 30, enabling electrical connection between at least one of the transmitter 10, receiver 20, and power supply 38, and the indicator light 33. The circuit board 35 can be a rigid circuit board 35, a flexible circuit board 35, or a combination of rigid and flexible circuit boards 35. It should be noted that when the circuit board 35 is a flexible circuit board 35, the wireless microphone charging case 30 may further include a reinforcing plate, which is disposed on one side of the flexible circuit board 35 to provide support for the flexible circuit board 35.

[0318] Multiple sets of indicator lights 33 are mounted on and electrically connected to the circuit board 35. The light-emitting surface of each set of indicator lights 33 (that is, the light-emitting surface of the lamp beads described above) abuts against the side wall of the corresponding mounting body 342. In this way, the light projected by each set of indicator lights 33 can be transmitted from the indicator light 33 to the mounting body 342 in contact with it with minimal loss, and then guided from the mounting body 342 to the corresponding light guide unit 343, and finally pass through the corresponding mounting position 312 to be obtained by the user's eyes.

[0319] As shown in Figures 34 and 35, the wireless microphone charging case 30 also includes a non-transparent partition 36. The partition 36 is located within the gap formed between two adjacent mounting bodies 342, and is connected to the inner wall of the case 31. The partition 36 can be, but is not limited to, a partition plate or a baffle. The specific connection method between the partition 36 and the inner wall of the case 31 is not limited here; designers can design it reasonably according to actual needs. For example, the partition 36 can be detachably connected to the inner wall of the case 31 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the partition 36 can be non-detachably connected to the inner wall of the case 31 by, but is not limited to, adhesive bonding, injection molding, or 3D printing. By designing a baffle 36 in the gap formed between two adjacent mounting bodies 342, the baffle 36 can further effectively block the light projected from the two adjacent indicator lights 33, thereby further improving the light crosstalk problem between the two adjacent indicator lights 33 and improving the indication accuracy of the indicator lights 33.

[0320] As shown in Figures 32 and 36, the wireless microphone charging case 30 also includes a support base 37 for mounting the circuit board 35; the support base 37 is located in the receiving cavity 311 of the case body 31 and is connected to the case body 31; the support base 37 has a receiving groove 371; each receiving groove 371 is used to avoid a set of indicator lights 33, and the plane of the groove opening of the receiving groove 371 is in contact with the side wall of the mounting body 342.

[0321] The support base 37 serves as another bracket for the wireless microphone charging case 30, supporting structural components such as the circuit board 35 and the power supply 38. The specific material used to manufacture the support base 37 is not limited; designers can choose according to actual needs. For example, the material of the support base 37 can be, but is not limited to, plastic or PVC. This ensures a wide availability of raw materials and effectively reduces the cost of the wireless microphone charging case 30. It should be noted that the materials used to manufacture the support base 37, charging base 32, and case 31 can be the same or different.

[0322] The support base 37 is disposed within the receiving cavity 311 of the compartment 31, and the support base 37 is connected to the compartment 31. The specific connection method between the support base 37 and the compartment 31 is not limited here; designers can design it reasonably according to actual needs. For example, the support base 37 can be detachably connected to the compartment 31 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the support base 37 can also be non-detachably connected to the compartment 31 by riveting or adhesive bonding, but not limited to this method.

[0323] The circuit board 35 is mounted on the support base 37. The specific connection method between the circuit board 35 and the support base 37 is not limited here, and the designer can make reasonable designs according to actual needs; for example, the circuit board 35 can be detachably connected to the support base 37 by at least one of the following methods: screwing, snap-fitting, or plugging; or, for example, the circuit board 35 can be non-detachably connected to the support base 37 by gluing or riveting.

[0324] By designing a receiving groove 371 on the circuit board 35 to avoid the indicator light 33, and fitting the plane where the groove opening of the receiving groove 371 is located with the side wall of the mounting body 342, the indicator light 33 is covered in the receiving groove 371. The mounting body 342 can concentrate and guide the light projected by the indicator light 33, which can further effectively improve the light crosstalk problem between two adjacent indicator lights 33.

[0325] Fifth embodiment

[0326] Please refer to Figures 37-39. In the first aspect, this application proposes a wireless microphone charging case 1, in which the user can directly determine the power of the transmitter 2 and / or receiver 3 according to the power display mechanism 30, making the operation more convenient and the practicality stronger.

[0327] The wireless microphone charging case 1 includes a case body 10, a charging base 20, and a power display mechanism 30. The case body 10 defines a top-opening receiving cavity 11. The charging base 20 is at least partially disposed within the receiving cavity 11, and the charging base 20 has a charging slot 21 with its opening facing the cavity 11; the charging slot 21 is used to accommodate a transmitter 2 and a receiver 3. The power display mechanism 30 is disposed in the case body 10, and the power display mechanism 30 is used to display the power level of at least one of the transmitter 2 and the receiver 3.

[0328] The following section, in conjunction with Figures 37-44, will provide a detailed description of the specific structure of the wireless microphone charging case 1.

[0329] As shown in Figures 37-39, the wireless microphone charging case 1 includes a case body 10, a charging base 20, and a power display mechanism 30.

[0330] The housing 10 serves as the shell of the wireless microphone charging case 1. The specific shape of the housing 10 is not limited here; designers can design it appropriately according to actual needs. For example, the outer contour of the housing 10 can be, but is not limited to, a cuboid or cylinder-like shape. The specific material used to manufacture the housing 10 is also not limited here; designers can choose appropriately according to actual needs. For example, the material used to manufacture the housing 10 can be, but is not limited to, plastic or PVC. This ensures that the raw materials are widely available and easily accessible, effectively reducing the cost of the wireless microphone charging case 1.

[0331] The chamber 10 defines a top-open receiving cavity 11.

[0332] The charging stand 20 serves as a support for the wireless microphone charging case 1, supporting the transmitter 2 and the receiver 3. The specific materials used to manufacture the charging stand 20 are not limited here; designers can choose according to actual needs. For example, the charging stand 20 can be made of, but is not limited to, plastic or plastic material. This allows for a wide range of readily available raw materials and effectively reduces the cost of the wireless microphone charging case 1.

[0333] The charging base 20 is at least partially located within the receiving cavity 11 of the housing 10. The specific connection method between the charging base 20 and the housing 10 is not limited here; designers can design it reasonably according to actual needs. For example, the charging base 20 can be detachably connected to the housing 10 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the charging base 20 can be non-detachably connected to the housing 10 by riveting or adhesive bonding, but not limited to this method.

[0334] The charging base 20 has a charging slot 21 with its opening facing the cavity 11 of the housing 10; the charging slot 21 is used to accommodate the transmitter 2 and the receiver 3.

[0335] The power display mechanism 30 serves as the power display structure for the wireless microphone charging case 1; the specific form of the power display mechanism 30 will be described in detail below.

[0336] The power display mechanism 30 is installed on the compartment 10. There are no restrictions on the installation method of the power display mechanism 30 on the compartment 10 or the specific connection method between the power display mechanism 30 and the compartment 10. Designers can make reasonable designs according to actual needs. It is also understood that the installation method of the power display mechanism 30 on the compartment 10 and the specific connection method between the power display mechanism 30 and the compartment 10 will be different for different specific forms of power display mechanism 30.

[0337] The power display mechanism 30 is used to display the power level of at least one of the transmitter 2 and the receiver 3. For example, the power display mechanism 30 can be used to display the power level of the transmitter 2 alone; or, for example, it can be used to display the power level of the receiver 3 alone; or, for example, it can be used to display the power levels of both the transmitter 2 and the receiver 3. It should be noted that the power level displayed by the power display mechanism 30 can be the remaining power of the transmitter 2 and / or the receiver 3, or it can be the charging power of the transmitter 2 and / or the receiver 3. For example, when the transmitter 2 and the receiver 3 are in use, the user can determine the current remaining power of the transmitter 2 and / or the receiver 3 based on the power display mechanism 30; or, for example, when the transmitter 2 and the receiver 3 are charging, the user can determine the current charging power of the transmitter 2 and / or the receiver 3 based on the power display mechanism 30.

[0338] Based on the wireless microphone charging case 1 in this application embodiment, a power display mechanism 30 is designed to directly display the power level of at least one of the transmitter 2 and receiver 3. In this way, the user can directly determine the power level of the transmitter 2 and / or receiver 3 based on the power display mechanism 30. Compared with related technologies that rely on external terminals such as mobile phones or computers to view the power level of the transmitter 2 and / or receiver 3, this method is more convenient and more practical.

[0339] As shown in Figures 37-39, the charging slot 21 includes a first charging slot 21a for accommodating the transmitter 2; the power display mechanism 30 includes a first indicator light 31 for displaying the power level of the transmitter 2; the first indicator light 31 is disposed on the side wall of the housing 10 corresponding to the first charging slot 21a. A first mounting hole (not shown in the figures) is provided in the area of ​​the side wall of the housing 10 corresponding to the first charging slot 21a, and the first indicator light 31 is inserted into the first mounting hole. By designing the first indicator light 31, the user can determine the power level of the transmitter 2 based on the display status of the first indicator light 31; by designing the first indicator light 31 on the side wall of the housing 10 corresponding to the first charging slot 21a, it is convenient for the user to more intuitively determine the power level of the transmitter 2 based on the display status of the first indicator light 31, and the spatial layout of the first indicator light 31 and the first charging slot 21a is more compact, facilitating wiring.

[0340] As shown in Figures 37-39, the charging slot 21 further includes a second charging slot 21b for accommodating the receiver 3; the power display mechanism 30 further includes a second indicator light 32 for displaying the power level of the receiver 3; the second indicator light 32 is disposed on the side wall of the housing 10 corresponding to the second charging slot 21b. A second mounting hole (not shown in the figures) is provided in the area of ​​the side wall of the housing 10 corresponding to the second charging slot 21b, and the second indicator light 32 is inserted into the second mounting hole. By designing the second indicator light 32, the user can determine the power level of the receiver 3 based on the display status of the second indicator light 32; by designing the second indicator light 32 on the side wall of the housing 10 corresponding to the second charging slot 21b, it is convenient for the user to more intuitively determine the power level of the receiver 3 based on the display status of the second indicator light 32, and also makes the spatial layout of the second indicator light 32 and the second charging slot 21b more compact, facilitating wiring.

[0341] As shown in Figures 37-39, the first charging slot 21a and the second charging slot 21b are arranged along a first preset direction MM'. The first indicator light 31 includes multiple first LED beads 311 disposed on the side wall of the housing 10; the multiple first LED beads 311 are arranged at intervals along a second preset direction NN', and the multiple first LED beads 311 display the transmitter 2's battery level according to a first preset display method. The second indicator light 32 includes multiple second LED beads 321 disposed on the side wall of the housing 10; the multiple second LED beads 321 are arranged at intervals along a second preset direction NN', and the multiple second LED beads 321 display the receiver 3's battery level according to a second preset display method. The second preset direction NN' intersects with the first preset direction MM'.

[0342] When the outer contour of the compartment 10 is a cuboid, the number of first charging slots 21a can be one, and the number of second charging slots 21b can be two. In this case, one first charging slot 21a and two second charging slots 21b are arranged along the length direction of the compartment 10 (one of the first preset directions MM' mentioned above).

[0343] The number of first LED beads 311 can be two, three, four, five, six or more; when the outer contour of the compartment 10 is a cuboid, multiple first LED beads 311 can be arranged along the height direction of the compartment 10 (one of the above-mentioned second preset directions NN').

[0344] The first LED bead 311 displays the power level of the transmitter 2 according to the first preset display mode; wherein, the first LED bead 311 has different display states such as always on, always off, and flashing, and the power level of the transmitter 2 can be determined according to the arrangement and combination of different display states of multiple first LED beads 311. For example, let's define the power level of transmitter 2 as Q1 and the full charge level of transmitter 2 as Qf. Taking the first indicator light 31, which includes four first LED beads 311, as an example: When 0.75Qf≤Q1≤Qf, all four first LED beads 311 are in a constantly lit display state; when 0.5Qf≤Q1<0.75Qf, three first LED beads 311 are in a constantly lit display state, and the remaining first LED bead 311 is in a constantly off display state; when 0.25Qf≤Q1<0.5Qf, two first LED beads 311 are in a constantly lit display state, and the remaining two first LED beads 311 are in a constantly off display state; when 0<Q1<0.25Qf, one first LED bead 311 is in a constantly lit display state, and the remaining three first LED beads 311 are in a constantly off display state; when Q1=0, all four first LED beads 311 are in a constantly off display state.

[0345] The number of second LED beads 321 can be two, three, four, five, six or more; when the outer contour of the compartment 10 is cuboid, the multiple second LED beads 321 can be arranged along the height direction of the compartment 10. Of course, in other embodiments, the multiple second LED beads 321 can also be arranged at intervals along a third preset direction different from the first preset direction MM' and the second preset direction NN'.

[0346] The second LED 321 displays the battery level of the receiver 3 according to the second preset display mode; wherein, the second LED 321 has different display states such as always on, always off, and flashing, and the battery level of the receiver 3 can be determined according to the arrangement and combination of different display states of multiple second LEDs 321. For example, let's define the battery level of receiver 3 as Q2 and the full charge level of receiver 3 as Qr. Taking the second indicator light 32, which includes four second LEDs 321, as an example: When Q2 = Qr, all four second LEDs 321 are constantly lit; when 0.75Qr < Q2 < Qr, three second LEDs 321 are constantly lit, and the remaining second LED 321 is flashing; when Q2 = 0.75Qr, all three second LEDs 321 are constantly lit, and the remaining second LED 321 is off; when 0.5Qr < Q2 < 0.75Qr, two second LEDs 321 are constantly lit, one of the remaining second LEDs 321 is flashing, and the remaining second LED 321 is off. Display status: When Q2 = 0.5Qr, both second LEDs 321 are in a constantly lit display state, and the remaining two second LEDs 321 are in a constantly off display state; when 0.25Qr < Q2 < 0.5Qr, one second LED 321 is in a constantly lit display state, one of the remaining second LEDs 321 is in a flashing display state, and the remaining two second LEDs 321 are in a constantly off display state; when Q2 = 0.25Qr, one second LED 321 is in a constantly lit display state, and the remaining three second LEDs 321 are in a constantly off display state; when 0 < Q2 < 0.25Qr, one second LED 321 is in a flashing display state, and the remaining three second LEDs 321 are in a constantly off display state; when Q2 = 0, all four second LEDs 321 are in a constantly off display state. Of course, in other embodiments, the multiple first LED beads 311 and the multiple second LED beads 321 can also display the power of the transmitter 2 and the receiver 3 in the same preset display mode.

[0347] It should be noted that the first indicator light 31 may also include a first LED 311, in which case the first LED 311 can display different colors, and the power level of the transmitter 2 can be determined based on the different colors displayed by the first LED 311. The second indicator light 32 may also include a second LED 321, in which case the second LED 321 can display different colors, and the power level of the receiver 3 can be determined based on the different colors displayed by the second LED 321.

[0348] As shown in Figures 38 and 40, the wireless microphone charging case 1 also includes a circuit board 40 and a power supply 50. The circuit board 40 is disposed within the receiving cavity 11 of the case 10 and located below the charging slot 21. The charging terminals (not shown in the figures) of the circuit board 40 pass through the bottom wall of the charging slot 21 for electrical connection with the charging ports of the transmitter 2 and the receiver 3. The power supply 50 is disposed within the receiving cavity 11 of the case 10 and is electrically connected to the circuit board 40. The power display mechanism 30 is electrically connected to the circuit board 40 and is also used to display the power level of the power supply 50.

[0349] The circuit board 40 serves as the electrical connector of the wireless microphone charging case 1, enabling electrical connections between the power supply 50, transmitter 2, receiver 3, and power display mechanism 30. The circuit board 40 can be a rigid circuit board, a flexible circuit board, or a combination of both. It should be noted that when the circuit board 40 is a flexible circuit board, the wireless microphone charging case 1 may also include a reinforcing plate, which is disposed on one side of the flexible circuit board 40 to provide support. The specific connection method between the circuit board 40 and the case 10 is not limited here; designers can design it reasonably according to actual needs. For example, the circuit board 40 can be detachably connected to the case 10 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the circuit board 40 can be non-detachably connected to the case 10 by adhesive bonding, but is not limited to this method.

[0350] The power supply 50 serves as the power transmission component of the wireless microphone charging case 1. It supplies power to the transmitter 2 and receiver 3, and also receives power from an external power source 50 (such as a power bank or 220V AC mains). The power supply 50 may include, but is not limited to, a battery. The specific connection method between the power supply 50 and the case 10 is not limited here; designers can design it reasonably according to actual needs. For example, the power supply 50 may be detachably connected to the case 10 via at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the power supply 50 may be non-detachably connected to the case 10 via adhesive bonding.

[0351] The power display mechanism 30 is also used to display the power level of the power supply 50. It should be noted that the power level displayed by the power display mechanism 30 can be the remaining power level of the power supply 50 or the charging level of the power supply 50; for example, when the wireless microphone charging case 1 is in a discharging state, the user can determine the current remaining power level of the power supply 50 according to the power display mechanism 30; and for another example, when the wireless microphone charging case 1 is in a charging state, the user can determine the current charging level of the power supply 50 according to the power display mechanism 30.

[0352] By designing the circuit board 40 to be electrically connected to the power supply 50, the power supply 50 can charge the transmitter 2 and receiver 3 housed in the charging slot 21 through the charging terminals of the circuit board 40. By designing the power display mechanism 30 to be electrically connected to the power supply 50 through the circuit board 40, the power display mechanism 30 can obtain the power level of the power supply 50 and display the power level of the power supply 50, so that the user can determine the power level of the power supply 50 based on the power display mechanism 30.

[0353] As shown in Figures 37-38, when the power display mechanism 30 is also used to display the power of the power supply 50, the power display mechanism 30 also includes a third indicator light 33; the third indicator light 33 is used to display the power of the power supply 50, and the third indicator light 33 is further away from the opening of the receiving cavity 11 of the compartment 10 than the first indicator light 31 and the second indicator light 32.

[0354] The side wall of the compartment 10 is provided with a third mounting hole, into which a third indicator light 33 is inserted. By designing the third indicator light 33, the user can determine the power level of the power supply 50 based on the display status of the third indicator light 33.

[0355] The third indicator light 33 includes a plurality of third LED beads 331 disposed on the side wall of the compartment 10; the plurality of third LED beads 331 are arranged at intervals along a first preset direction MM'. For example, the number of third LED beads 331 can be two, three, four, five, six or more; when the outer contour shape of the compartment 10 is cuboid, the plurality of third LED beads 331 can be arranged along the length direction of the compartment 10 (one of the aforementioned first preset directions MM').

[0356] The third LED 331 displays the power level of the power supply 50 according to a preset display mode. The third LED 331 has different display states such as constantly on, constantly off, and flashing. The power level of the power supply 50 can be determined by the arrangement and combination of different display states of multiple third LEDs 331. The specific placement of the third LED 331 is not limited here; designers can design it reasonably according to actual needs. It should be noted that multiple third LEDs 331 and the aforementioned multiple second LEDs 321 or multiple first LEDs 311 can display the power level of the power supply 50 according to the same preset display mode, or they can display the power level of the power supply 50 according to different preset display modes. Of course, the third indicator light 33 can also include a single third LED 331. In this case, the single third LED 331 can display different colors, and the power level of the power supply 50 can be determined based on the different colors displayed by the single third LED 331.

[0357] As shown in Figure 37, the wireless microphone charging case 1 also includes a top cover 60; the top cover 60 is rotatably connected to the case body 10 to open or close the cavity 11 of the case body 10. When the top cover 60 is rotated to open the cavity 11 of the case body 10, the first indicator light 31 displays the power level of the transmitter 2 according to a first preset display mode, the second indicator light 32 displays the power level of the receiver 3 according to a second preset display mode, and the third indicator light 33 displays the power level of the power supply 50 according to a preset display mode; when the top cover 60 is rotated to close the cavity 11 of the case body 10, the first indicator light 31, the second indicator light 32, and the third indicator light 33 are turned off.

[0358] Of course, the specific form of the power display mechanism 30 can also be different from the first indicator light 31, the second indicator light 32, and the third indicator light 33 mentioned above; as shown in Figure 5, the power display mechanism 30 includes a display screen 34 for displaying the power of the transmitter 2 and the receiver 3; the display screen 34 is disposed on the side wall of the compartment 10. When the top cover 60 is rotated to open the cavity 11 of the compartment 10, the display screen 34 is lit for a preset time; when the top cover 60 is rotated to close the cavity 11 of the compartment 10, the display screen 34 is turned off.

[0359] The display screen 34 is used to display the battery levels of the transmitter 2 and receiver 3. The specific connection method between the display screen 34 and the housing 10 is not limited; designers can design it according to actual needs. For example, the front side wall of the housing 10 has a window communicating with the receiving cavity 11, and the display screen 34 extends into the receiving cavity 11 corresponding to the window. The display screen 34 can be detachably connected to the housing 10 by a snap-fit ​​method, but is not limited to a non-detachable connection by adhesive bonding. The specific value of the "preset time" is not limited; designers can design it according to actual needs. For example, the preset time can be, but is not limited to, 3 seconds, 5 seconds, 6 seconds, or 10 seconds, etc. Of course, the display screen 34 can also be used to display the battery level of the power supply 50.

[0360] By designing the display screen 34, when the top cover 60 rotates to the opening of the receiving cavity 11 of the open compartment 10 under external force, the display screen 34 is illuminated. At this time, the user can directly obtain the power levels of the transmitter 2 and receiver 3 through the data displayed on the display screen 34. By designing the display screen 34 to be illuminated for a preset time, power saving can be achieved. In addition, the top cover 60 will not remain illuminated indefinitely when it rotates to the opening of the receiving cavity 11 of the open compartment 10 under unexpected circumstances.

[0361] Other structural designs between the charging base 20 and the housing 10 may be, but are not limited to, one or more of the following embodiments.

[0362] As shown in Figures 38 and 39, in the first embodiment, the charging base 20 is connected to the housing 10 by a snap-fit ​​mechanism. This facilitates the installation and removal of the charging base 20 from the housing 10. Specifically, the periphery of the charging base 20 is provided with at least one of a snap-fit ​​block 91 and a snap-fit ​​groove 92; the edge of the cavity 11 of the housing 10 is provided with at least the other of a snap-fit ​​block 91 and a snap-fit ​​groove 92; the snap-fit ​​block 91 and the snap-fit ​​groove 92 are engaged to position the charging base 20 on the housing 10. The snap-fit ​​block 91 can be integrally formed with the charging base 20 and / or the housing 10 by injection molding or 3D printing, but is not limited to this method.

[0363] As shown in Figures 38 and 39, in the second embodiment, the back of the housing 10 has a notch 12 at the edge of the cavity opening of the receiving cavity 11; the wireless microphone charging housing 1 also includes a fixing seat 70 and a connecting seat 80; the fixing seat 70 is connected to the housing 10 corresponding to the notch 12; the top cover 60 is rotatably connected to the fixing seat 70; the connecting seat 80 is connected to the charging base 20 corresponding to the notch 12, and the connecting seat 80 and the fixing seat 70 are detachably connected. The connecting seat 80 can be integrally formed with the charging base 20 by, but is not limited to, injection molding or 3D printing.

[0364] Specifically, the specific connection method between the fixed seat 70 and the compartment 10, and the specific connection method between the connecting seat 80 and the fixed seat 70, may include, but are not limited to, one or more of the following embodiments.

[0365] As shown in Figures 42 and 43, in the first embodiment, the connecting seat 80 and the fixing seat 70 are connected by screws. This facilitates the assembly of the charging seat 20 and the housing 10.

[0366] As shown in Figures 42 and 43, in the second embodiment, the connecting seat 80 has a first positioning part 93 on the side facing the fixed seat 70; the fixed seat 70 has a second positioning part 94 on the side facing the connecting seat 80; the second positioning part 94 engages with the first positioning part 93. By designing the second positioning part 94 to engage with the first positioning part 93, assembly between the fixed seat 70 and the connecting seat 80 is facilitated, thereby assembling the compartment 10 and the charging seat 20. The first positioning part 93 can be, but is not limited to, a physical structure such as a positioning block or positioning shaft provided on the connecting seat 80; in this case, the second positioning part 94 can be, but is not limited to, a virtual structure such as a positioning hole or positioning groove formed on the fixed seat 70. Alternatively, the first positioning part 93 can also be, but is not limited to, a virtual structure such as a positioning hole or positioning groove formed on the connecting seat 80; in this case, the second positioning part 94 can be, but is not limited to, a physical structure such as a positioning block or positioning shaft provided on the fixed seat 70. Of course, the first positioning part 93 may also be, but is not limited to, a combination of a solid structure such as a positioning shaft provided on the connecting seat 80 and a virtual structure such as a positioning hole formed on the connecting seat 80; in this case, the second positioning part 94 may be, but is not limited to, a combination of a virtual structure such as a positioning hole formed on the fixed seat 70 and a solid structure such as a positioning block provided on the fixed seat 70.

[0367] As shown in Figures 39 and 44, in the third embodiment, the bottom wall of the notch 12 is provided with a third positioning part 95; the side of the fixed seat 70 facing the bottom wall of the notch 12 is provided with a fourth positioning part 96; the fourth positioning part 96 is engaged with the third positioning part 95. By designing the fourth positioning part 96 to engage with the third positioning part 95, it is convenient to realize the assembly between the fixed seat 70 and the compartment 10; and when the fourth positioning part 96 and the third positioning part 95 are engaged, the outer side of the fixed seat 70 is flush with and coplanar with the outer side of the compartment 10. The third positioning part can be, but is not limited to, a solid structure such as a positioning block or a positioning shaft provided on the compartment 10; in this case, the fourth positioning part 96 can be, but is not limited to, a virtual structure such as a positioning hole or a positioning groove formed on the fixed seat 70. The third positioning part 95 can also be, but is not limited to, a virtual structure such as a positioning hole or a positioning groove formed on the compartment 10; in this case, the fourth positioning part 96 can be, but is not limited to, a solid structure such as a positioning block or a positioning shaft provided on the fixed seat 70. Of course, the third positioning part 95 may also be, but is not limited to, a combination of a solid structure such as a positioning block provided on the compartment 10 and a virtual structure such as a positioning groove formed on the connecting seat 80; in this case, the fourth positioning part 96 may be, but is not limited to, a combination of a virtual structure such as a positioning groove formed on the fixed seat 70 and a solid structure such as a positioning block provided on the fixed seat 70.

[0368] It should be noted that the fixed seat 70 and the compartment 10 are matched in a first-level snap-fit ​​through the fourth positioning part 96 and the third positioning part 95; the fixed seat 70 and the connecting seat 80 are matched in a second-level snap-fit ​​through the second positioning part 94 and the first positioning part 93, and the fixed seat 70 is connected to the connecting seat 80 by screws. This multi-screw connection greatly improves the connection stability between the fixed seat 70, the connecting seat 80 and the compartment 10.

[0369] Referring to Figures 37 and 41, in a second aspect, this application proposes a wireless microphone charging system; the wireless microphone charging system includes a transmitter 2, a receiver 3, and the aforementioned wireless microphone charging compartment 1; the transmitter 2 and the receiver 3 are installed in the charging slot 21.

[0370] Based on the wireless microphone charging system in this application embodiment, which has the aforementioned wireless microphone charging case 1, users can directly determine the power level of the transmitter 2 and / or receiver 3 according to the power display mechanism 30, making operation more convenient and practical.

[0371] Sixth Embodiment

[0372] Please refer to Figure 46. This application proposes a wireless microphone charging system 1, which includes a wireless microphone charging case 10 and a wireless microphone transmitter 20.

[0373] As shown in Figures 45 and 46, the wireless microphone charging case 10 serves as the charging box for the wireless microphone charging system 1. It is used to charge the wireless microphone transmitter 20 on one hand and to store the wireless microphone transmitter 20 on the other.

[0374] The wireless microphone charging case 10 includes a charging base 11 and a first magnetic element 12.

[0375] The charging stand 11 serves as a support for the wireless microphone charging case 10, supporting the wireless microphone transmitter 20. The specific materials used to manufacture the charging stand 11 are not limited here; designers can choose according to actual needs. For example, the materials used to manufacture the charging stand 11 can be, but are not limited to, plastic or PVC. This ensures that the raw materials are widely available and easily accessible, effectively reducing the cost of the wireless microphone charging case 10.

[0376] The charging dock 11 has a first charging slot 11a for accommodating the wireless microphone transmitter 20. It should be noted that the first charging slot 11a on the charging dock 11 is usually formed by mold injection molding or 3D printing so that the shape of the first charging slot 11a matches the shape of the corresponding wireless microphone transmitter 20.

[0377] The arc-shaped groove wall 111 of the first charging groove 11a has a charging port 111a; it should be noted that the first charging groove 11a is formed by multiple groove walls together, and the "groove wall" here refers to the three-dimensional solid part corresponding to the wall thickness of the first charging groove 11a.

[0378] The first magnetic member 12 serves as a limiting member for the wireless microphone charging case 10. It is used to magnetically attach with the second magnetic member 23 (described below) of the wireless microphone transmitter 20 to achieve relative fixation between the wireless microphone transmitter 20 and the charging base 11, thereby effectively reducing or even avoiding the possibility of the wireless microphone transmitter 20, which is housed in the first charging slot 11a, shaking.

[0379] The first magnetic suction member 12 is disposed on at least one side of the charging port 111a along the arc length direction of the arc-shaped groove wall 111; for example, the first magnetic suction member 12 may be disposed on one side of the charging port 111a along the arc length direction of the arc-shaped groove wall 111; or, for another example, the first magnetic suction member 12 may be disposed on both sides of the charging port 111a along the arc length direction of the arc-shaped groove wall 111. It should be noted that the first magnetic suction member 12 may be at least partially embedded in the wall thickness of the arc-shaped groove wall 111, or may be attached to the outer surface of the arc-shaped groove wall 111. The specific connection method between the first magnetic suction member 12 and the arc-shaped groove wall 111 is not limited here, and the designer can make reasonable designs according to actual needs; for example, the first magnetic suction member 12 may be detachably connected to the arc-shaped groove wall 111 by at least one of the following methods: snap-fit ​​or plug-in; or, for another example, the first magnetic suction member 12 may be non-detachably connected to the arc-shaped groove wall 111 by adhesive bonding.

[0380] As shown in Figures 46-49, the wireless microphone transmitter 20 is used for sound reception. The wireless microphone transmitter 20 includes a housing 21, a cover 22, and a second magnetic component 23.

[0381] The housing 21 serves as the outer shell of the wireless microphone transmitter 20. The specific material used to manufacture the housing 21 is not limited here; designers can make a reasonable selection based on actual needs. For example, the material used to manufacture the housing 21 can be, but is not limited to, plastic or PVC. This allows for a wide range of readily available raw materials and effectively reduces the cost of the wireless microphone transmitter 20.

[0382] The housing 21 has a bottom wall 211 and an arcuate side wall 212 surrounding the bottom wall 211; the bottom wall 211 and the arcuate side wall 212 enclose and form an installation cavity 213.

[0383] The cover 22 serves as the end cap of the wireless microphone transmitter 20. The specific material used to manufacture the cover 22 is not limited here; designers can make a reasonable choice based on actual needs. For example, the material used to manufacture the cover 22 can be, but is not limited to, plastic or PVC. This allows for a wide range of readily available raw materials and effectively reduces the cost of the wireless microphone transmitter 20.

[0384] The cover 22 is connected to at least one of the bottom wall 211 and the side wall to cover the opening of the mounting cavity 213. The cover 22 may be connected only to the bottom wall 211, only to the side wall, or to both. The specific connection method between the cover 22 and the bottom wall 211 and / or the side wall is not limited here; designers can design it reasonably according to actual needs. For example, the cover 22 may be connected to the bottom wall 211 and / or the side wall by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection.

[0385] The second magnetic component 23 serves as a limiting component for the wireless microphone transmitter 20. It is used to magnetically attach with the first magnetic component 12 to achieve relative fixation between the wireless microphone transmitter 20 and the charging base 11, thereby effectively reducing or even avoiding the possibility of the wireless microphone transmitter 20, which is housed in the first charging slot 11a, shaking.

[0386] The second magnetic chuck 23 is disposed on the arc-shaped sidewall 212. The specific connection method between the second magnetic chuck 23 and the arc-shaped sidewall 212 is not limited here; designers can design it reasonably according to actual needs. For example, the second magnetic chuck 23 can be detachably connected to the arc-shaped sidewall 212 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the second magnetic chuck 23 can also be non-detachably connected to the arc-shaped sidewall 212 by adhesive bonding, but not limited to this method. In this embodiment, a slot is provided on the inner side of the arc-shaped sidewall 212, and the second magnetic chuck 23 is inserted into the slot.

[0387] When the wireless microphone transmitter 20 is housed in the first charging slot 11a, the second magnetic member 23 is positioned opposite to the first magnetic member 12. The magnetic attraction force generated between the second magnetic member 23 and the first magnetic member 12 includes a lateral component force pointing towards the arc-shaped slot wall 111. Under the action of this lateral component force, the arc-shaped sidewall 212 keeps the housing 21 in contact with the slot wall surface of the first charging slot 11a, thus achieving relative fixation between the wireless microphone transmitter 20 and the charging base 11. This effectively reduces or even avoids the possibility of the wireless microphone transmitter 20, housed in the first charging slot 11a, shaking, thereby effectively preventing damage to precision components such as chips.

[0388] It should be noted that the second magnetic chuck 23 and the first magnetic chuck 12 are close to each other, and the two are suitable for generating a magnetic attraction force. For example, the second magnetic chuck 23 may include a magnet, and the first magnetic chuck 12 may include a steel sheet. In this case, the magnet of the second magnetic chuck 23 is close to the steel sheet of the first magnetic chuck 12, and the two generate a magnetic attraction force. Alternatively, the second magnetic chuck 23 may also include a steel sheet, and the first magnetic chuck 12 may include a magnet. In this case, the steel sheet of the second magnetic chuck 23 is close to the magnet of the first magnetic chuck 12, and the two generate a magnetic attraction force. Yet another example is that the second magnetic chuck 23 may also include a magnet, and the first magnetic chuck 12 may include another magnet. In this case, the magnet of the second magnetic chuck 23 is close to the other magnet of the first magnetic chuck 12, and the two generate a magnetic attraction force.

[0389] As shown in Figure 45, the wireless microphone system also includes a wireless microphone receiver 30; the wireless microphone receiver 30 is used to connect to the user terminal and transmit audio signals to the user terminal; the specific structure of the receiver is not limited here, and designers can make reasonable designs according to actual needs.

[0390] The charging dock 11 also has a second charging slot 11b for accommodating the wireless microphone receiver 30. It should be noted that the second charging slot 11b on the charging dock 11 is usually formed by mold injection molding or 3D printing so that the shape of the second charging slot 11b matches the shape of the corresponding wireless microphone receiver 30.

[0391] The wireless microphone charging case 10 also includes a case body 13 (serving as the outer shell of the wireless microphone charging case 10). The specific shape of the case body 13 is not limited here; designers can design it appropriately according to actual needs. For example, the outer contour shape of the case body 13 can be, but is not limited to, a cuboid or cylindrical shape. The specific material used to manufacture the case body 13 is also not limited here; designers can choose appropriately according to actual needs. For example, the material used to manufacture the case body 13 can be, but is not limited to, plastic or PVC; this ensures that the raw materials are widely available and easily accessible, and effectively reduces the cost of the wireless microphone charging case 10.

[0392] The compartment 13 defines a top-open receiving cavity (not shown in the figure); the receiving cavity is the space inside the compartment 13 that can be used, but is not limited to, to accommodate components such as the charging base 11; it should be noted that the slot openings of the first charging slot 11a and the second charging slot 11b are both oriented towards the opening of the receiving cavity.

[0393] The charging base 11 is at least partially located within the receiving cavity of the compartment 13. The specific connection method between the charging base 11 and the compartment 13 is not limited here; designers can design it reasonably according to actual needs. For example, the charging base 11 can be detachably connected to the compartment 13 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the charging base 11 can be non-detachably connected to the compartment 13 by riveting or adhesive bonding, but not limited to this method.

[0394] As shown in Figure 45, the wireless microphone charging case 10 also includes a top cover 14, which is rotatably connected to the case body 13 to open or close the cavity of the case body 13.

[0395] As shown in Figure 46, the first magnetic chuck 12 has a first surface 12a facing the arc-shaped groove wall 111; the distance between the first surface 12a and the plane containing the charging port 111a gradually decreases from the side near the central axis of the charging port 111a to the side away from the central axis of the charging port 111a. The second magnetic chuck 23 has a second surface 23a facing the arc-shaped sidewall 212; the distance between the second surface 23a and the plane containing the charging port 111a gradually increases from the side near the central axis of the charging port 111a to the side away from the central axis of the charging port 111a. When the wireless microphone transmitter 20 is housed in the first charging slot 11a, the second magnetic chuck 23 is positioned opposite to the first magnetic chuck 12, and the magnetic attraction force generated between the second magnetic chuck 23 and the first magnetic chuck 12 also includes a vertical component pointing towards the arc-shaped groove wall 111. Under the action of the vertical component force, the arc-shaped sidewall 212 makes the charging interface 24 (described below) of the wireless microphone transmitter 20 tightly connected to the charging port 111a provided on the arc-shaped groove wall 111 of the first charging groove 11a, so as to ensure the effectiveness of charging.

[0396] As shown in Figures 46-48, the first magnetic clasp 12 is disposed on both sides of the charging port 111a along the arc length of the arc-shaped groove wall 111. The wireless microphone transmitter 20 also includes a charging interface 24; the charging interface 24 is disposed on the arc-shaped side wall 212 and is used to connect to the charging port 111a when the wireless microphone transmitter 20 is housed in the first charging groove 11a. The second magnetic clasp 23 is disposed on both sides of the charging interface 24 along the arc length of the arc-shaped side wall 212. The specific connection method between the charging interface 24 and the arc-shaped side wall 212 is not limited here; designers can design it reasonably according to actual needs. For example, the charging interface 24 can be detachably connected to the arc-shaped side wall 212 by means of snap-fit ​​or plug-in; or, for example, the charging interface 24 can be non-detachably connected to the arc-shaped side wall 212 by means of adhesive bonding. By distributing the first magnetic clasp 12 along the arc length of the arc-shaped groove wall 111 on both sides of the charging port 111a, and distributing the second magnetic clasp 23 along the arc length of the arc-shaped side wall 212 on both sides of the charging interface 24, when the wireless microphone transmitter 20 is housed in the first charging slot 11a, the magnetic attraction between the second magnetic clasp 23 on both sides of the charging interface 24 and the first magnetic clasp 12 on both sides of the charging port 111a, under the action of the lateral component of the magnetic attraction force on both sides of the charging interface 24, ensures that multiple sides of the housing 21 are always in contact with the groove wall of the first charging slot 11a, further improving the stability of the wireless microphone transmitter 20 housed in the first charging slot 11a, thereby further reducing or even avoiding the possibility of the wireless microphone transmitter 20 shaking when housed in the first charging slot 11a, and effectively preventing damage to precision components such as chips.

[0397] As shown in Figures 49-50, the charging interface 24 is located at the bottom of the arc-shaped sidewall 212. This facilitates effective connection between the charging interface 24 and the charging port 111a, thereby enabling effective charging. Specifically, the bottom of the arc-shaped sidewall 212 has multiple sockets communicating with the mounting cavity 213; the charging interface 24 includes multiple interface terminals 241; the multiple interface terminals 241 are inserted one-to-one into the multiple sockets.

[0398] As shown in Figures 48 and 51, the wireless microphone transmitter 20 also includes a clamping structure 25. The clamping structure 25 is disposed on the cover 22 and is configured to cooperate with the cover 22 to fix an external object to be clamped between the clamping structure 25 and the cover 22. The external object to be clamped can be, but is not limited to, the user's clothing. In this way, the user can use the clamping structure 25 to fix the wireless microphone transmitter 20 to the external object, freeing the user's hands and improving the ease of use of the wireless microphone transmitter 20.

[0399] For example, the clamping structure 25 is configured to magnetically engage with the cover 22 to fix the object to be clamped between the clamping structure 25 and the cover 22. Specifically, the cover 22 includes a cover body 221 and a first magnetic element (not shown in the figure); the cover body 221 is connected to at least one of the bottom wall 211 and the arcuate side wall 212 to cover the opening of the mounting cavity 213, and the cover body 221 has a mounting groove 221a on the side facing away from the opening of the mounting cavity 213; the first magnetic element 12 is located in the mounting groove 221a and connected to the cover body 221. The clamping structure 25 includes a clamping cover 251 and a second magnetic element 252; the clamping cover 251 is disposed corresponding to the mounting groove 221a; the second magnetic element 252 is disposed on the side of the clamping cover 251 facing the opening of the mounting cavity 213. The first magnetic component can be detachably connected to the cover body 221 by at least one of the following methods: screwing, snap-fitting, or plugging; or it can be non-detachably connected to the cover body 221 by adhesive bonding. The second magnetic component 252 can be detachably connected to the clip cover 251 by at least one of the following methods: screwing, snap-fitting, or plugging; or it can be non-detachably connected to the clip cover 251 by adhesive bonding. The second magnetic component 252 and the magnetic suction component are brought close together to generate a magnetic attraction force. For example, the second magnetic component 252 may include a magnet, and the first magnetic component may include a steel sheet. In this case, the magnet of the second magnetic component 252 is brought close to the steel sheet of the first magnetic component, and a magnetic attraction force is generated between them to fix the object to be clamped between the cover 251 and the cover body 221. Alternatively, the second magnetic component 252 may also include a steel sheet, and the first magnetic component may include a magnet. In this case, the steel sheet of the second magnetic component 252 is brought close to the magnet of the first magnetic component, and a magnetic attraction force is generated between them to fix the object to be clamped between the cover 251 and the cover body 221. Yet another example is that the second magnetic component 252 may also include a magnet, and the first magnetic component may include another magnet. In this case, the magnet of the second magnetic component 252 is brought close to the other magnet of the first magnetic component, and a magnetic attraction force is generated between them to fix the object to be clamped between the cover 251 and the cover body 221.

[0400] For example, the clamping structure 25 is configured to rotatably clamp the cover 22 to fix the object to be clamped between the clamping structure 25 and the cover 22. Specifically, the clamping structure 25 includes a clamp (not shown in the figure), a pivot (not shown in the figure), and a torsion spring (not shown in the figure); the clamp is connected to the cover 22 via the pivot; the torsion spring is wound around the pivot, with one end of the torsion spring abutting against the clamp and the other end of the torsion spring abutting against the cover 22.

[0401] Other structural designs for the wireless microphone transmitter 20 may include, but are not limited to, one or more of the following embodiments.

[0402] As shown in Figure 52, in the first embodiment, a pickup hole 212a is provided at the top of the arc-shaped sidewall 212. By designing the pickup hole 212a at the top of the arc-shaped sidewall 212, the sound reception effect of the wireless microphone transmitter 20 can be effectively improved.

[0403] As shown in Figure 52, in the second embodiment, the wireless microphone transmitter 20 also includes a power button 26; the power button 26 is disposed on the arc-shaped sidewall 212. By designing the power button 26 on the arc-shaped sidewall 212, it is convenient for users to perform power on and off operations, thereby improving the ease of use of the wireless microphone transmitter 20.

[0404] As shown in Figure 52, in the third embodiment, the wireless microphone transmitter 20 also includes a mute button 27; the mute button 27 is disposed on the arc-shaped sidewall 212. By designing the mute button 27 on the arc-shaped sidewall 212, the user can trigger the mute button 27 according to the actual application scenario, thereby improving the ease of use of the wireless microphone transmitter 20.

[0405] As shown in Figure 53, in the fourth embodiment, the wireless microphone transmitter 20 further includes an indicator light 28. The indicator light 28 is disposed on the arc-shaped sidewall 212, located on the side of the pickup hole 212a extending along the arc length of the arc-shaped sidewall 212. The indicator light 28 can be, but is not limited to, indicating the current state of the wireless microphone transmitter 20; for example, when the indicator light 28 is lit, it indicates that the wireless microphone transmitter 20 is in the powered-on state; when the indicator light 28 is off, it indicates that the wireless microphone transmitter 20 is in the powered-off state. By designing the indicator light 28, users can confirm the current state of the wireless microphone transmitter 20 according to the indicator light 28, improving the ease of use of the wireless microphone transmitter 20.

[0406] Specifically, the power button 26 and the mute button 27 are located on the same side of the microphone hole 212a, with the power button 26 being further away from the microphone hole 212a than the mute button 27. This makes it easier for users to operate the power button 26 and the mute button 27, improving the ease of use of the wireless microphone transmitter 20.

[0407] Seventh Embodiment

[0408] First, please refer to Figure 54, which is a circuit block diagram of a charging case control circuit provided in an embodiment of this application.

[0409] As shown in Figure 54, the charging case control circuit provided in this embodiment of the application is used to charge the wireless microphone device. The wireless microphone device includes a first transmitter 11, a second transmitter 12 and a receiver 13. The charging case control circuit 100 provided in this embodiment of the application includes a power supply chip 20, a switching circuit 30 and a controller 40.

[0410] The power supply chip 20 includes a first charging output terminal 21, a second charging output terminal 22, and a first power output terminal 23. The first charging output terminal 21 is electrically connected to the first transmitter 11 to charge the first transmitter 11, and the second charging output terminal 22 is electrically connected to the second transmitter 12 to charge the second transmitter 12. The switching circuit 30 includes a power supply input terminal 32, a power supply output terminal 33, and a control terminal 31. The power supply input terminal 32 is electrically connected to the first power output terminal 23 of the power supply chip 20, and the power supply output terminal 33 is electrically connected to the receiver 13 to charge the receiver 13. The power supply chip 20 can be a power supply chip 20 for various Bluetooth headset charging cases.

[0411] The controller 40 is electrically connected to the control terminal 31 of the switching circuit 30 and communicatively connected to the power supply chip 20. The switching circuit 30 switches between on and off states according to the control signal issued by the controller 40. The controller 40 can also be configured to issue commands to the power supply chip 20 to configure parameters such as the output power of the power supply chip 20. The controller 40 can be implemented using a microcontroller, microprocessor, programmable logic device, etc. The switching circuit 30 can be implemented using various metal-oxide-semiconductor field-effect transistors, bipolar transistors, junction field-effect transistors, etc.

[0412] As can be seen, the charging case control circuit 100 provided in this application embodiment charges the first transmitter 11 and the second transmitter 12 respectively through the first charging output terminal 21 and the second charging output terminal 22 of the power supply chip 20. At the same time, it is electrically connected to the transmitter through the switching circuit 30. The controller 40 controls the working state of the switching circuit 30 to charge the transmitter. Thus, a single power supply chip 20 can charge the first transmitter 11, the second transmitter 12 and the receiver 13 at the same time. Therefore, the structure of the charging case control circuit 100 is simplified, the product cost is reduced and the product stability is improved.

[0413] In some embodiments, the charging case control circuit 100 further includes a rechargeable battery 50. The rechargeable battery 50 can be used to power the charging case control circuit 100, and the charging case control circuit 100 can charge the rechargeable battery 50. The rechargeable battery 50 can be, for example, a lithium battery or a nickel-metal hydride battery.

[0414] In some embodiments, the charging case control circuit 100 further includes an access detection circuit 60, which is electrically connected to the power supply output terminal 33 of the switch circuit 30, the rechargeable battery 50, and the controller 40. After the receiver 13 is connected to the power supply output terminal 33 of the switch circuit 30 (i.e., entering the charging case for charging), the access detection circuit 60 generates an access signal (e.g., a high level or a low level) and sends it to the controller 40. The controller 40 can generate a corresponding control signal (e.g., a high level or a low level) based on the access signal and send it to the control terminal 31 of the switch circuit 30, thereby enabling the switch circuit 30 to operate in a conducting state. In this way, the power supply chip 20 can provide power to the receiver 13 through the first power output terminal 23 via the switch circuit 30, thereby powering the receiver 13.

[0415] Referring also to Figure 55, in some embodiments, the access detection circuit 60 includes a sixth resistor R6, a first diode D1, and a fifth resistor R5 connected in series. The positive terminal of the first diode D1 is electrically connected to the rechargeable battery 50 through the sixth resistor R6, and the negative terminal of the first diode D1 is electrically connected to the INOUTDET pin of the controller 40 through the fifth resistor R5. The negative terminal of the first diode D1 is also electrically connected to the power supply output terminal 33 of the switching circuit 30. When the receiver 13 is connected to the power supply output terminal 33 of the switching circuit 30, the access detection circuit 60 generates an access signal on the INOUTDET pin of the controller 40 through the fifth resistor R5. After detecting the presence of an access signal on the INOUTDET pin, the controller 40 issues a control signal to control the switching circuit 30 to operate in the on state.

[0416] Referring again to Figure 55, in some embodiments, the switching circuit 30 includes a first transistor Q1, a second transistor Q2, a third transistor Q3, a first resistor R1, a second resistor R2, and a third resistor R3. The drain of the first transistor Q1 serves as the power input terminal 32 of the switching circuit 30 and is electrically connected to the first power output terminal 23 of the power supply chip 20. The source of the first transistor Q1 is electrically connected to the source of the second transistor Q2, and the gate of the first transistor Q1 is connected to the gate of the second transistor Q2. The first resistor R1 is connected between the source and gate of the first transistor Q1. The drain of the second transistor Q2 serves as the power supply output terminal 33 of the switching circuit 30 and is electrically connected to the positive terminal RX+ of the charging input terminal of the receiver 13. The gate of the third transistor Q3 is electrically connected to the controller 40 via the second resistor R2. The drain of the third transistor Q3 is electrically connected to the gate of the first transistor Q1. The source of the third transistor Q3 is grounded. The third resistor R3 is connected between the gate of the third transistor Q3 and ground. In this embodiment, the first transistor Q1 and the second transistor Q2 are enhancement-mode P-channel MOSFETs, and the third transistor Q3 is an enhancement-mode N-channel MOSFET. The drain of the first transistor Q1 serves as the power supply input terminal 32 of the switching circuit 30, the drain of the second transistor Q2 serves as the power supply output terminal 33, and the end of the second resistor R2 furthest from the gate of the third transistor Q3 serves as the control terminal 31. When the control signal sent by the controller 40 to the control terminal 31 is high, the third transistor Q3 is turned on, and the first transistor Q1 and the second transistor Q2 are also turned on. The switching circuit 30 can then be considered to be in the on state. At this time, the power supply chip 20 supplies power to the receiver 13 through the first power output terminal 23, and the receiver 13 begins to charge. When the control signal is low, the third transistor Q3 is turned off, and the first transistor Q1 and the second transistor Q2 are also turned off. The switching circuit 30 is in the off state, and the power output terminal 33 of the switching circuit 30 has no power output, so the receiver 13 does not charge. It should be noted that because the parasitic body diodes inside the first transistor Q1 and the second transistor Q2 are reverse-connected, current can be prevented from flowing through the body diodes of the first transistor Q1 and the second transistor Q2, thus preventing interference with the normal operation of the circuit.

[0417] In some embodiments, the charging case control circuit 100 further includes a feedback resistor R4. One end of the feedback resistor R4 is grounded, and the other end of the feedback resistor R4 is electrically connected to the negative terminal RX- of the charging input terminal of the receiver 13 and the IDET pin of the controller 40. When the receiver 13 is connected to the power supply output terminal 33 and starts charging, the charging current will generate a feedback signal on the feedback resistor R4. After receiving the feedback signal through the IDET pin, the controller 40 can control the output parameters of the power supply chip 20 according to the magnitude of the feedback signal, thereby adjusting the charging current of the receiver 13 to achieve constant current charging of the receiver 13.

[0418] In some embodiments, the charging case control circuit 100 further includes an input terminal 70 for connection to an external power adapter. The input terminal 70 may be an input terminal 70 conforming to various interface standards, such as a USB Type A or Type C interface terminal.

[0419] Referring also to Figure 56, in some embodiments, the charging case control circuit 100 further includes a first inductor L, a first capacitor C1, a second capacitor C2, and a third capacitor C3. The first inductor L and the first capacitor C1 are connected in series between the power supply chip 20 and ground, while the second capacitor C2 and the third capacitor C3 are connected in parallel between the first power output terminal 23 of the power supply chip 20 and ground. The power supply chip 20, the first inductor L, the first capacitor C1, the second capacitor C2, and the third capacitor C3 form a Boost converter circuit to perform voltage conversion, converting the externally input power supply voltage into the DC voltage required for charging.

[0424] Eighth embodiment

[0425] Referring to Figures 57 to 60, an embodiment of this application proposes a charging case, including a case body 10, a case cover 20, and a Z-shaped spring 30; the case cover 20 is hinged to the case body 10, and the Z-shaped spring 30 is disposed between the case body 10 and the case cover 20; when the case cover 20 is opened from the case body 10, the Z-shaped spring 30 can generate a first limiting resistance to prevent the case cover 20 from closing relative to the case body 10; when the case cover 20 is closed to the case body 10, the Z-shaped spring 30 can generate a second limiting resistance to prevent the case cover 20 from opening relative to the case body 10.

[0426] In this embodiment, the charging case 10 is used to hold electronic products such as microphones, and also to charge them. When placing electronic products, after the cover 20 is hinged open from the case 10, the Z-shaped spring 30 generates a first limiting resistance on the cover 20, preventing it from closing onto the case 10 due to accidental events such as mistake. This allows the user to easily place electronic products and avoids operational errors. When the cover 20 is closed on the case 10, the Z-shaped spring 30 generates a second limiting resistance, preventing the cover 20 from opening from the case 10, thus preventing accidental opening of the cover 20.

[0427] Specifically, under the action of the Z-shaped spring 30, the hatch cover 20 has an equilibrium point relative to the hatch body 10. When the hatch cover 20 is half-open relative to the hatch body 10 (i.e., the hatch cover 20 is not fully open relative to the hatch body 10), the Z-shaped spring 10 will neither generate the first limiting resistance nor be in the second limiting resistance position. However, when the hatch cover 20 crosses this equilibrium point, it will generate the first limiting resistance or the second limiting resistance, thereby generating a force that prevents the hatch cover 20 from closing or opening, thus preventing the hatch cover 20 from being accidentally opened or closed.

[0428] In one embodiment, the Z-shaped spring 30 is a Z-shaped torsion spring. One end of the Z-shaped torsion spring is disposed on the compartment cover 20, and the other end of the Z-shaped torsion spring abuts against the compartment body 10. The rotational connection position of the Z-shaped spring 30 and the compartment cover 20 is eccentrically set with the hinged rotation position of the compartment cover 10. Therefore, there is a balance point between the compartment cover 20 and the compartment body 10. When this balance point is exceeded, the Z-shaped torsion spring can generate a first limiting resistance or a second limiting resistance between the compartment cover 20 and the compartment body 10.

[0429] In one embodiment, the cover 20 is provided with a mounting portion 22, and the mounting portion 22 has a first mounting hole 222. One end of the Z-shaped torsion spring passes through the first mounting hole 222. One end of the Z-shaped torsion spring can be fixed through the first mounting hole 222 of the mounting portion 22.

[0430] In one embodiment, the container body 10 is provided with a rotating shaft 40, and the container cover 20 is provided with a rotating part 24. The rotating part 24 is rotatably mounted on the rotating shaft 40, so that the container cover 20 is hinged to the container body 10. By providing the rotating shaft 40 and the rotating part 24, the container cover 20 can smoothly rotate relative to the container body 10, making operation convenient.

[0431] Both ends of the Z-shaped torsion spring are capable of coiling deformation. When the lid 20 rotates relative to the body 10, the end of the Z-shaped torsion spring away from the body 10 will rotate upward around the rotation axis 40. During the upward rotation of the end of the Z-shaped torsion spring away from the body 10, the end of the Z-shaped torsion spring located inside the body 10 is always in close contact with the inner wall of the body 10. During this process, as the lid 20 is driven by external force, the Z-shaped torsion spring will undergo corresponding coiling deformation through the bending part.

[0432] As shown in Figure 57, arrow A indicates the direction of the thrust of the Z-shaped torsion spring in this case. If no external force is applied, and the force direction at the connection point between the cover 20 and the Z-shaped torsion spring points below the rotation shaft 40, that is, the mounting part 22 is located below the rotation shaft 40, the cover 20 will tend to close onto the compartment body 10 under the action of the Z-shaped torsion spring.

[0433] As shown in Figure 58, arrow B indicates the direction of the thrust of the Z-shaped torsion spring in this case. If no external force is applied, and the force at the connection point between the cover 20 and the Z-shaped torsion spring points above the rotation shaft 40, that is, the mounting part 22 is located above the rotation shaft 40, the Z-shaped torsion spring will prevent the cover 20 from closing onto the compartment body 10.

[0434] If the force direction at the connection point between the Z-shaped torsion spring and the cover 20 points to the pivot, this is the dead point position, but the end of the cover 20 will still tend to close onto the compartment body 10 due to the weight.

[0435] Under the condition that no external force is applied, the force source at the connection point between the cover 20 and the Z-shaped torsion spring is the rebound deformation force of the Z-shaped torsion spring.

[0436] In one embodiment, the housing 10 includes an outer shell 14, an inner shell 16, and a charging assembly 18. The inner shell 16 is disposed on the outer shell 14, forming an installation space between the inner shell 16 and the outer shell 14. The charging assembly 18 is disposed in the installation space, and the inner shell 16 has a receiving space. A mounting groove 15 is formed between the inner shell 16 and the outer shell 14, and the rotating shaft 40 is located within the mounting groove 15. The installation space is used to install the charging assembly 18, and the receiving space is used to hold electronic products. The mounting groove 15 is used to install the rotating shaft 40, resulting in a compact and rationally designed structure.

[0437] In one embodiment, the inner shell 16 has a first arc surface, and the outer shell 14 has a second arc surface. The first arc surface and the second arc surface are located on the side wall of the mounting groove 15 and are arranged around the rotation axis 40. By providing the first arc surface and the second arc surface, the rotation of the compartment cover 20 relative to the compartment body 10 is made smoother.

[0438] In one embodiment, the charging compartment further includes an adsorption device 50, which is disposed on the compartment body 10 and / or the compartment cover 20. After the compartment cover 20 is closed on the compartment body 10, the adsorption device 50 exerts an adsorption force on the compartment cover 20 to adsorb and fix the compartment cover 20 and the compartment body 10 in place. When the compartment cover 20 is closed on the compartment body 10, the adsorption device 50 ensures that the compartment cover 20 and the compartment body 10 are relatively fixed, preventing the compartment cover 20 and the compartment body 10 from opening accidentally.

[0439] In one embodiment, the adsorption device 50 includes a first magnet 52 and a second magnet 54. The first magnet 52 is disposed on the cover 20, and the second magnet 54 is disposed on the body 10. By providing the first magnet 52 and the second magnet 54, the cover 20 and the body 10 can be relatively fixed, preventing them from opening accidentally. It is understood that the adsorption device 50 can also be other structures capable of adsorption and fixation.

[0440] In one embodiment, the Z-shaped torsion spring is integrally formed and includes a connecting arm 31, a first spiral coil 32, a second spiral coil 33, a first torsion arm 34, and a second torsion arm 35. The connecting arm 31 connects the first spiral coil 32 and the second spiral coil 33. The first torsion arm 34 is disposed on the first spiral coil 32, and the second torsion arm 35 is disposed on the second spiral coil 33. The first torsion arm 34, the connecting arm 31, and the second torsion arm 35 form a Z-shape. The first torsion arm 34 is rotatably mounted on the bin cover, and the second torsion arm 35 is disposed on the bin body. The connecting arm 31 generates an elastic thrust on the first torsion arm 34 through the first spiral coil 32, and the connecting arm 31 also generates an elastic thrust on the second torsion arm 35 through the second spiral coil 33. When the first torsion arm 34 acts on the bin cover and the second torsion arm 35 acts on the bin body, a first limiting resistance or a second limiting resistance can be generated.

[0441] In one embodiment, the first spiral coil 32 has at least two spiral turns, and the second spiral coil 33 has at least two spiral turns. When the number of spiral turns of the first spiral coil 32 and the number of spiral turns of the second spiral coil 33 are greater than or equal to two, the elastic potential energy can be increased, thereby increasing the first limiting resistance and the second limiting resistance, and thus improving the effect of preventing the cover from being opened or closed accidentally.

[0442] In one embodiment, the first torsion arm 34 and the second torsion arm 35 are of equal length, so that the two ends of the Z-shaped torsion spring can be used interchangeably, which provides good replaceability and eliminates the need for foolproof settings.

[0443] In one embodiment, the first torsion arm 34 and the second torsion arm 35 are both straight rods. This can increase the contact area between the first torsion arm 34 and the compartment cover, and also increase the contact area between the second torsion arm 35 and the compartment body.

[0444] Embodiments of this application also propose an electronic device including the aforementioned charging case. The electronic device of this embodiment also possesses the aforementioned advantages, which will not be elaborated upon here.

[0445] In one embodiment, the electronic device further includes an electronic product 200, and the charging case 10 is capable of housing the electronic product 200 and charging it. The electronic product 200 can be a microphone, transmitter, receiver, etc., and the user can select the type of electronic product 200 as needed.

[0446] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in each of the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of each embodiment of the present invention.

[0447] Ninth Embodiment

[0448] Referring to Figures 61 and 62, an embodiment of the present invention provides a charging compartment 100, including a compartment body 10, a compartment cover 20, and a limiting device 30; the compartment cover 20 is hinged to the compartment body 10, and the limiting device 30 is disposed on the compartment body 10 and the compartment cover 20; when the compartment cover 20 is opened from the compartment body 10, the limiting device 30 can generate a first limiting resistance on the compartment cover 20 to prevent the compartment cover 20 from closing relative to the compartment body 10.

[0449] The charging case 100 in this embodiment is used to charge the microphone. Specifically, the microphone can be placed inside the case 10. When the microphone is inside the case 10, the case 10 can charge the microphone. During charging, the case cover 20 can be closed on the case 10. Therefore, during use, the case cover 20 can be hinged and rotated relative to the case 10, which facilitates user operation. When the case cover 20 is opened, during the process of placing the microphone into the case 10, the limiting device 30 can generate a first limiting resistance, which can prevent the case cover 20 from closing on the case 10, thus facilitating the user's operation of placing the microphone into the case 10. After the microphone is placed into the case 10, the user can push the case cover 20 to overcome the first limiting resistance and close the case cover 20 on the case 10 without affecting the normal closing and use of the case cover 20 and the case 10.

[0450] Referring to Figures 62 to 65, in one embodiment, the limiting device 30 includes a first limiting block 32 and a second limiting block 34. A rotating shaft 40 is provided on the compartment body 10, and a rotating part 50 is provided on the compartment cover 20. The rotating part 50 is rotatably mounted on the rotating shaft 40, so that the compartment cover 20 is hinged to the compartment body 10. The first limiting block 32 is mounted on the rotating part 50, and the second limiting block 34 is mounted on the compartment body 10. When the compartment cover 20 is opened from the compartment body 10, the first limiting block 32 and the second limiting block 34 cooperate to generate a first limiting resistance that prevents the compartment cover 20 from closing relative to the compartment body 10. The rotating part 50 and the rotating shaft 40 cooperate to allow the compartment cover 20 and the compartment body 10 to rotate hingedly. By setting the first limiting block 32 and the second limiting block 34, a first limiting resistance can be generated on the compartment cover 20, resulting in a simple structure and convenient operation. Preferably, the surfaces of the first limiting block 32 and the second limiting block 34 are arc surfaces, which makes it more convenient for the user to push the cover 20 to overcome the first limiting resistance.

[0451] In one embodiment, the surface of the rotating part 50 is an arc surface, and the central axis of the arc surface coincides with the central axis of the rotating shaft 40. The first limiting block 32 is located on the arc surface. A mounting groove 12 is provided on the side of the compartment 10. The mounting groove 12 includes a top wall 122, a side wall 124, and a bottom wall 126 connected in sequence. The second limiting block 34 is located on the side wall 124. By providing a rotating part 50 with an arc surface, the compartment cover 20 rotates more smoothly relative to the compartment 10. In this embodiment, the top wall 122 is located near the top of the compartment 10, the bottom wall 126 is located near the bottom of the compartment 10, and the side wall 124 is parallel to the side of the compartment 10.

[0452] In one embodiment, at least a portion of one end face of the compartment cover 20 extends and protrudes to form a mounting portion 60. The rotating portion 50 is located inside the mounting portion 60, and the end of the mounting portion 60 forms a first stop 62. The bottom surface of the second limiting block 34 forms a second stop 342. When the compartment cover 20 is opened from the compartment body 10, the second stop 342 and the first stop 62 cooperate to generate a second limiting resistance on the compartment cover 20, preventing the compartment cover 20 from continuing to open relative to the compartment body 10. By setting the first stop 62 and the second stop 342, the hinged opening angle of the compartment cover 20 relative to the compartment body 10 is prevented from being too large.

[0453] In one embodiment, the mounting groove 12 is further provided with a clearance space 128 for the first stop 62 to avoid obstruction, and the clearance space 128 is located on the bottom wall 126. By providing the clearance space 128, the cooperation between the first stop 62 and the second stop 342 is made smoother.

[0454] In one embodiment, the bottom wall 126 is an inclined plane, with one end of the bottom wall 126 near the clearance space 128 tilting downwards. The inclined plane can also provide a certain limiting effect on the cover 20, preventing the cover 20 from opening at an excessive angle.

[0455] In one embodiment, the housing 10 includes an outer shell 14, an inner shell 16, and a charging assembly 18. The inner shell 16 is disposed on the outer shell 14, forming an installation space between the inner shell 16 and the outer shell 14. The charging assembly 18 is disposed in the installation space, and the inner shell 16 has a receiving space. A mounting groove 12 is formed between the inner shell 16 and the outer shell 14. The bottom wall 126 is located on the outer shell 14, and the top wall 122 and side walls 124 are located on the inner shell 16. The charging assembly 18 includes a battery, a circuit board, a USB interface, etc., which can be customized by the user as needed. By designing the inner shell 16 and the outer shell 14, it is easier to install the charging assembly 18 and use it more conveniently.

[0456] In one embodiment, the charging compartment 100 further includes an adsorption member 70 disposed within the compartment body 10. After the compartment cover 20 is closed on the compartment body 10, the adsorption member 70 exerts an adsorption force on the compartment cover 20, thereby adsorbing and fixing the compartment cover 20 to the compartment body 10. The adsorption member 70 can be a magnet, and a portion of the compartment cover 20 can be a magnet, or the compartment cover 20 can also be equipped with a magnet or iron. In this way, when the compartment cover 20 is closed on the compartment body 10, the adsorption member 70 can adsorb and fix the compartment cover 20 to the compartment body 10, preventing the compartment cover 20 from opening from the compartment body 10 due to operational errors or other factors.

[0457] Please refer to Figure 66 in conjunction with the present invention. An embodiment of the present invention also provides an electronic device 1000, including the aforementioned charging case 100. The electronic device 1000 of this embodiment also has the aforementioned advantages, which will not be repeated here.

[0458] In one embodiment, the electronic device 1000 further includes an electronic product body 200, and the charging case 100's housing 10 is capable of storing the electronic product body 200 and charging the electronic product body 200. The electronic product body 200 can be a microphone, transmitter, receiver, etc., and the user can select the type of electronic product body 200 as needed.

[0459] Tenth Embodiment

[0460] Referring to Figures 67 to 69, an embodiment of this application proposes a microphone charging case, including a base 10 and a flip cover 20. The base 10 has a first receiving groove 12, and the flip cover 20 has a second receiving groove 22. The first receiving groove 12 is used to receive an electronic product 30. The base 10 includes a first end 14 and a second end 16 opposite to each other. The flip cover 20 is hinged to the top of the base 10. The hinge point between the flip cover 20 and the base 10 is located at the first end 14. There is a hinge center O between the flip cover 20 and the base 10. The second receiving groove 12 has a first endpoint A that is closest to the hinge center on the side away from the hinge center. After the electronic product 30 is placed in the first receiving groove 12, the electronic product 30 has a second endpoint B that is farthest from the hinge center. The distance between the hinge center and the first endpoint is denoted as OA, and the distance between the hinge center and the second endpoint is denoted as OB. OA is greater than OB. Since OA is greater than OB, when the electronic product 30 is stored in the first receiving slot 12, there will be no interference between the inner wall of the second receiving slot 22 of the flip cover 20 and the electronic product 30 when the flip cover 20 is opened or closed. This ensures that the wall thickness of the flip cover 20 is uniform throughout, facilitating manufacturing. Furthermore, it eliminates the need to increase the height of the base 10 or the depth of the first receiving slot, making it easier to access the electronic product 30.

[0461] As shown in Figures 67 and 68, the height of the first end 14 can be greater than or equal to the height of the second end 16. The end of the flip cover 20 away from the first end 14 can easily avoid interference with the electronic product 30, that is, the inner wall of the second receiving groove 22 and the electronic product 30 can easily avoid interference.

[0462] In one embodiment, the top of the base 10 has a first inclined plane, and the bottom of the flip cover 20 has a second inclined plane that mates with the first inclined plane.

[0463] Therefore, the first and second inclined planes can serve as closing surfaces. On one hand, this design can provide a larger rotation radius for the second receiving slot 22, effectively preventing interference between the slot wall of the second receiving slot 22 and the end of the transmitter or receiver furthest from the hinge center, ensuring smooth operation of the flip cover 20. On the other hand, this design allows for a larger volume of the transmitter and receiver ends extending outside the first receiving slot 12 when the flip cover 20 is opened, facilitating easy removal by the user and optimizing the user experience. The inclined closing surface design allows more of the transmitter and receiver ends to be exposed on the inclined end facing the user after opening the cover. Since the indicator lights of the transmitter and receiver are generally located on the side wall, by setting the first and second inclined planes, the indicator lights can be partially exposed outside the first receiving slot 12. Users can intuitively determine whether the transmitter is charging or fully charged through the indicator lights without needing to check via a terminal.

[0464] In one embodiment, the flip cover 20 is provided with an anti-slip arc groove 24 at one end near the hinge center. By providing the anti-slip arc groove 24, interference between the flip cover 20 and the base 10 can be further avoided.

[0465] In one embodiment, the height of the first end 14 is lower than the height of the second end 16. When opening the flip cover 20, the user needs to apply downward force. This force is superimposed on the gravity at the hinge center of the flip cover 20. The volume ratio of the flip cover 20 near the rotation center is larger than that of the free end of the flip cover 20, resulting in a greater gravity.

[0466] In one embodiment, the height of the first end 14 is higher than the height of the second end 16. When the height of the first end 14 is higher than the height of the second end 16, it is easier to avoid interference between the inner wall of the second receiving groove 22 of the flip cover 20 and the electronic product 30. When opening the flip cover 20, the user needs to apply upward force, which helps to prevent the force from being superimposed. On the other hand, the volume ratio of the free end of the flip cover 20 is larger, thereby reducing the load on the fixed rotating end and the pivot of the flip cover 20 and reducing the structural wear of the flip cover 20.

[0467] In one embodiment, a stepped structure 18 is provided between the second end 16 and the flip cover 20, which can improve the sealing between the second end 16 and the flip cover 20 when the flip cover 20 is closed on the base 10.

[0468] In one embodiment, the stepped structure 18 has a glossy surface.

[0469] In one embodiment, the end of the opening of the first receiving slot 12 is glossy. This glossy design allows light from above the microphone charging case to be reflected back to the user when the user opens the flip cover 20 in well-lit areas, thus alerting the user to the location of the transmitter and receiver and improving the user experience.

[0470] Embodiments of this application also propose an electronic device including the aforementioned microphone charging case. The electronic device of this embodiment also possesses the aforementioned advantages, which will not be elaborated upon here.
