[0020] In the wireless microphone charging bin, an indicator light is required to display the remaining power of the power supply. When the indicator light is lit, due to the direct connection of adjacent light guide columns in the related art, the light projected by the indicator light will string to the light outlet corresponding to its adjacent indicator light, that is, the phenomenon of light crosstalk occurs, resulting in the user being unable to correctly read the power. Therefore, how to effectively improve the light crosstalk phenomenon of the indicator light has become an urgent problem to be solved.

[0022] The transmitter 10 is used for sound collection; the specific structure of the transmitter 10 is not limited here, and designers can make reasonable designs according to actual needs.

[0023] The receiver 20 is used for connecting to a usage terminal and transmitting an audio signal to the usage terminal; the specific structure of the receiver 20 is not limited here, and designers can make reasonable designs according to actual needs.

[0024] The wireless microphone charging case 30 serves as the charging box of the wireless microphone charging system 1. On the one hand, it is used to charge the transmitter 10 and the receiver 20, and on the other hand, it is used to store the transmitter 10 and the receiver 20.

[0025] As Figures 1-3 shown, the wireless microphone charging case 30 includes a case body 31, a charging base 32, and an indicator light 33.

[0026] The case body 31 serves as the housing of the wireless microphone charging case 30. The specific shape of the case body 31 is not limited here, and designers can make a reasonable design according to actual needs; for example, the outer contour shape of the case body 31 can be but is not limited to a cuboid-like or cylinder-like shape. The specific preparation material of the case body 31 is not limited here, and designers can make a reasonable selection according to actual needs; for example, the preparation material of the case body 31 can be but is not limited to one of plastics or plastics; in this way, the raw material source is wide, easy to obtain, and can effectively reduce the cost of the wireless microphone charging case 30.

[0027] The case body 31 defines a receiving cavity 311 that is open at the top; the receiving cavity 311 is a space inside the case body 31 that can be but is not limited to used to accommodate components such as the charging base 32.

[0028] The charging base 32 serves as the support of the wireless microphone charging case 30 for carrying the transmitter 10 and the receiver 20. The specific preparation material of the charging base 32 is not limited here, and designers can make a reasonable selection according to actual needs; for example, the preparation material of the charging base 32 can be but is not limited to one of plastics or plastics; in this way, the raw material source is wide, easy to obtain, and can effectively reduce the cost of the wireless microphone charging case 30.

[0029] At least part of the charging base 32 is located inside the receiving cavity 311 of the case body 31. The specific connection method between the charging base 32 and the case body 31 is not limited here, and designers can make a reasonable design according to actual needs; for example, the charging base 32 can be detachably connected to the case body 31 by at least one of screwing, clamping, or plugging; for another example, the charging base 32 can also be non-detachably connected to the case body 31 by riveting or gluing.

[0030] The charging base 32 has a charging slot 321 with the notch facing the opening of the receiving cavity 311 of the case body 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.

[0031] The indicator light 33 serves as the power indicator component of the wireless microphone charging case 30. Users can determine the power of at least one of the transmitter 10, the receiver 20, and the power supply 38 (which serves as the power transmission component of the wireless microphone charging case 30 and can, on the one hand, supply power to the transmitter 10 and the receiver 20, and on the other hand, receive power from an external power supply 38 (such as a power bank or the mains 220V)) according to the display mode of the indicator light 33. For example, the indicator light 33 can be used to display the power of the transmitter 10 alone; for another example, the indicator light 33 can also be used to display the power of the receiver 20 alone; for yet another example, the indicator light 33 can also be used to display the power of the power supply 38 alone; and so on. Such cases are not elaborated here. It should be noted that for the transmitter 10 and the receiver 20, the power displayed by the indicator light 33 can be the remaining power of the transmitter 10 and / or the receiver 20, or the charging power of the transmitter 10 and / or the receiver 20; for example, when the transmitter 10 and the receiver 20 are in use, users can determine the current remaining power of the transmitter 10 and / or the receiver 20 according to the display mode of the indicator light 33; for another example, when the transmitter 10 and the receiver 20 are in the charging state, users can determine the current charging power of the transmitter 10 and / or the receiver 20 according to the display mode of the indicator light 33. For the power supply 38, the power displayed by the indicator light 33 can be the charging power of the power supply 38 or the remaining power of the power supply 38; for example, when the power supply 38 is in the charging state, users can determine the current charging power of the power supply 38 according to the display mode of the indicator light 33; for another example, when the power supply 38 is in the discharging state, users can determine the current remaining power of the power supply 38 according to the display mode of the indicator light 33.

[0032] The number of the indicator lights 33 is multiple groups; for example, the number of the indicator lights 33 can be two groups, three groups, four groups, five groups, six groups or more. It should be noted that for each group of the indicator lights 33, each group of the indicator lights 33 includes at least one lamp bead; and the number of the lamp beads in multiple groups of the indicator lights 33 can be the same or different. The lamp beads have different display states such as being constantly on, constantly off, and flashing. Users can then determine the power of at least one of the transmitter 10, the receiver 20, and the power supply 38 according to the permutation and combination of the different display states of the lamp beads in multiple groups of the indicator lights 33. Of course, the lamp beads can also be in different display states by changing colors, and users can determine the power of at least one of the transmitter 10, the receiver 20, and the power supply 38 according to the different color display states of the lamp beads in multiple groups of the indicator lights 33.

[0033] The side wall of the bin body 31 is provided with multiple groups of mounting positions 312 that communicate with the accommodation cavity 311 and are arranged along the first preset direction MM'; for example, the number of the mounting positions 312 can be two groups, three groups, four groups, five groups, six groups or more. It should be noted that for each group of mounting positions 312, each group of mounting positions 312 includes at least one mounting hole; and the number of the mounting holes in the multiple groups of mounting positions 312 can be the same or different. It should be noted that when the outer contour shape of the bin body 31 is a cuboid, the multiple groups of mounting positions 312 can be arranged along the length direction of the bin body 31 (one of the above first preset directions MM').

[0034] As Figures 2-4 shown, the wireless microphone charging bin 30 further includes an indicator light light guiding structure 34; the indicator light light guiding structure 34 is a structural member for transmitting the light projected by the above indicator light 33 from the indicator light 33 to another point at a certain distance from the indicator light 33 with the least loss; the indicator light light guiding structure 34 includes a connecting seat 341, a mounting body 342 and a light guiding unit 343.

[0035] The connecting seat 341 serves as the base of the indicator light light guiding structure 34; the specific structure of the connecting seat 341 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the connecting seat 341 can but is not limited to be in a plate-like structure or a frame structure.

[0036] At least part of the connecting seat 341 is located in the accommodation cavity 311 of the bin body 31; for example, part of the connecting seat 341 can be located in the accommodation cavity 311 of the bin body 31, and the remaining part extends out of the accommodation cavity 311 of the bin body 31 through the bottom wall of the bin body 31; or for another example, the connecting seat 341 can also be entirely located in the accommodation cavity 311 of the bin body 31.

[0037] The connecting seat 341 is used to connect with the bin body 31. The specific connection method between the connecting seat 341 and the bin body 31 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the connecting seat 341 can but is not limited to be detachably connected to the bin body 31 by at least one of the ways such as screwing, clamping or plugging; or for another example, the connecting seat 341 can also but is not limited to be non-detachably connected to the bin body 31 by gluing or riveting.

[0038] The mounting body 342 serves as the carrier of the indicator light light guiding structure 34 for carrying the light guiding unit 343; the specific structure of the mounting body 342 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the mounting body 342 can but is not limited to be in a columnar structure, a strip structure or a block structure.

[0039] The installation body 342 is located within the accommodation cavity 311 of the bin body 31, and the installation body 342 is connected to the connection base 341. The specific connection method between the installation body 342 and the connection base 341 is not limited herein, and the designer can make a reasonable design according to actual needs. For example, the installation body 342 can be integrally formed with the connection base 341 by injection molding or 3D printing, but is not limited thereto.

[0040] The number of the installation bodies 342 is multiple. For example, the number of the installation bodies 342 can be two, three, four, five, six or more. The multiple installation bodies 342 are arranged at intervals along the first preset direction MM', that is, a gap is formed between two adjacent installation bodies 342.

[0041] The multiple installation bodies 342 are arranged in one-to-one correspondence with multiple groups of indicator lights 33, that is, each group of indicator lights 33 corresponds to one installation body 342.

[0042] The light guide unit 343 serves as a light guide member of the indicator light light guide structure 34. The specific structure of the light guide unit 343 is not limited herein, and the designer can make a reasonable design according to actual needs. For example, the conduit unit can be in a columnar structure or a block structure, but is not limited thereto.

[0043] The number of the groups of light guide units 343 is multiple. For example, the number of the groups of light guide units 343 can be two, three, four, five, six or more. The multiple groups of light guide units 343 are connected to the multiple installation bodies 342 in one-to-one correspondence, that is, each installation body 342 is connected with a group of light guide units 343. The specific connection method between the light guide unit 343 and the installation body 342 is not limited herein, and the designer can make a reasonable design according to actual needs. For example, the light guide unit 343 can be integrally formed with the installation body 342 by injection molding or 3D printing, but is not limited thereto.

[0044] Each group of light guide units 343 is used to be arranged corresponding to a group of installation positions 312. In this way, the light projected by each group of indicator lights 33 is first guided to the corresponding installation body 342, then guided from the corresponding installation body 342 to the corresponding light guide unit 343, and finally passes through the corresponding installation position 312 and is acquired by the user's eyes.

[0045] By designing multiple independent mounting bodies 342 and connecting multiple groups of light guiding units 343 to the multiple mounting bodies 342 in a one-to-one correspondence, different mounting bodies 342 can guide the light projected by different indicating lights 33 to the corresponding light guiding units 343, and the gap formed between two adjacent mounting bodies 342 can effectively block the light projected by two adjacent indicating lights 33. In this way, the problem of light crosstalk between two adjacent indicating lights 33 can be effectively improved. By designing the connecting seat 341, the connecting seat 341 is connected to the multiple mounting bodies 342 to realize the integrated design of multiple groups of light guiding units 343. In this way, there is no need to set multiple single light guiding unit 343 parts to achieve light guiding, which has the advantages of saving part costs and being convenient for assembly.

[0046] As Figures 4-5 shown, the mounting body 342 includes a mounting post 342a extending along a second preset direction NN'; the second preset direction NN' intersects with the first preset direction MM'. The connecting seat 341 includes a base 341a; at least a part of the base 341a is located in the accommodating cavity 311 of the housing 31 and is connected to the bottom end of the mounting post 342a, and the base 341a is used for detachably connecting to the bottom wall of the housing 31. By designing the detachable connection between the base 341a and the bottom wall of the housing 31, the detachable connection between the indicating light light guiding structure 34 and the bottom wall of the housing 31 can be realized. In this way, it is beneficial to improve the disassembly and assembly efficiency of the indicating light light guiding structure 34. When the dust collection of the indicating light light guiding structure 34 affects the light guiding effect, the convenient disassembly and replacement of the indicating light light guiding structure 34 can be realized.

[0047] Among them, when the outer contour shape of the housing 31 is a cuboid, the mounting body 342 may include a mounting post 342a extending along the height direction of the housing 31 (one of the above second preset directions NN').

[0048] The base 341a serves as one of the bases of the connecting seat 341, and the number of the bases 341a can be one or more (more than two). The specific structure of the base 341a is not limited here, and the designer can make a reasonable design according to the actual situation. For example, when the number of the bases 341a is one, the one base 341a can be in the shape of a long strip plate structure, and the one base 341a is connected to the bottom ends of all the mounting posts 342a. The specific detachable connection method between the base 341a and the bottom wall of the bin body 31 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, when the base 341a is detachably connected to the bottom wall of the bin body 31 by screwing, the base 341a is provided with countersunk holes, and the bottom wall of the bin body 31 is provided with threaded holes corresponding to the countersunk holes. Screws pass through the countersunk holes and are connected to the threaded holes to position the base 341a on the bottom wall of the bin body 31. Another example is that when the base 341a is detachably connected to the bottom wall of the bin body 31 by clamping, the base 341a is provided with clamping grooves, and the bottom wall of the bin body 31 is provided with clamping blocks. The clamping blocks are clamped with the clamping grooves to position the base 341a on the bottom wall of the bin body 31. Still another example is that when the base 341a is detachably connected to the bottom wall of the bin body 31 by plugging, the base 341a is provided with plug holes, and the bottom wall of the bin body 31 is provided with pins. The pins are plugged with the plug holes to position the base 341a on the bottom wall of the bin body 31.

[0049] As Figures 4-5 shown, the connecting seat 341 further includes a top seat 341b. The top seat 341b is at least partially located in the accommodation cavity 311 and is connected to the top ends of the mounting posts 342a. The top seat 341b is used for detachably connecting with the side wall of the bin body 31. By designing the detachable connection between the top seat 341b and the side wall of the bin body 31, the detachable connection between the indicator light light guide structure 34 and the side wall of the bin body 31 can be realized. In this way, it is beneficial to improve the disassembly and assembly efficiency of the indicator light light guide structure 34. When the dust collection of the indicator light light guide structure 34 affects the light guide effect, the convenient disassembly and replacement of the indicator light light guide structure 34 can be realized. It is worth mentioning that the base 341a is detachably connected to the bottom wall of the bin body 31, and the top seat 341b is detachably connected to the side wall of the bin body 31. In this way, the indicator light light guide structure 34 is fixed on the bottom wall and the side wall of the bin body 31, which can effectively improve the connection stability between the indicator light light guide structure 34 and the bin body 31.

[0050] Among them, the top base 341b serves as another base of the connecting base 341, and the number of the top bases 341b can be one or more (more than two). The specific structure of the top base 341b is not limited here, and designers can make reasonable designs according to the actual situation. For example, when the number of the top bases 341b is one, the one top base 341b can be in a strip structure, and the one top base 341b is connected to the tops of all the mounting posts 342a. The specific detachable connection method between the top base 341b and the side wall of the bin body 31 is not limited here, and designers can make reasonable designs according to actual needs. For example, when the top base 341b is detachably connected to the side wall of the bin body 31 by screwing, the top base 341b is provided with counterbore holes, the side wall of the bin body 31 is provided with threaded holes corresponding to the counterbore holes, and screws pass through the counterbore holes and are connected to the threaded holes to position the top base 341b on the side wall of the bin body 31. Another example is that when the top base 341b is detachably connected to the side wall of the bin body 31 by clamping, the top base 341b is provided with clamping grooves, the side wall of the bin body 31 is provided with clamping blocks, and the clamping blocks are clamped with the clamping grooves to position the top base 341b on the side wall of the bin body 31. Still another example is that when the top base 341b is detachably connected to the side wall of the bin body 31 by plugging, the top base 341b is provided with insertion holes, the side wall of the bin body 31 is provided with pins, and the pins are inserted into the insertion holes to position the top base 341b on the side wall of the bin body 31.

[0051] It can be understood that the number of the bottom bases 341a can be one or more, and the number of the top bases 341b can be one or more. Regardless of the specific numbers of the bottom bases 341a and the top bases 341b, as long as the bottom bases 341a and the top bases 341b can connect multiple mounting posts 342a into one body. As Figure 4 shown, the number of the bottom bases 341a is two, and the number of the top bases 341b is one; the two bottom bases 341a are respectively and correspondingly connected to the bottoms of the two outermost mounting posts 342a; the top base 341b is connected to the tops of all the mounting posts 342a. In this way, the two bottom bases 341a and the one top base 341b connect multiple mounting posts 342a into one body, realizing the integrated design of multiple groups of light guiding units 343, and there is no need to set multiple single light guiding unit 343 parts to realize light guiding, which has the advantages of saving part costs and being convenient for assembly.

[0052] As Figure 4 shown, the light guiding unit 343 includes a light guiding column 343a; the light guiding column 343a is arranged at the middle position of the mounting post 342a. It should be noted that for each group of light guiding units 343, the number of the light guiding columns 343a in each group of light guiding units 343 can be one or more; and the numbers of the light guiding columns 343a in multiple groups of light guiding units 343 can be the same or different, and the light guiding columns 343a in each group of light guiding units 343 are inserted into the mounting holes of the corresponding mounting positions 312.

[0053] Other designs of the connection base 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.

[0054] In the first embodiment, the connection base 341, the mounting body 342, and the light guide unit 343 are integrally formed. For example, the connection base 341, the mounting body 342, and the light guide unit 343 may be formed into an integral structure by, but are not limited to, injection molding or 3D printing. This can effectively reduce the processing difficulty of the entire indicator light guide structure 34.

[0055] In the second embodiment, the preparation material of at least one of the connection base 341, the mounting body 342, and the light guide unit 343 is one of acrylic resin, polycarbonate, epoxy resin, and glass. This gives the entire indicator light guide structure 34 good light guiding properties.

[0056] As Figures 2-3 shown, the wireless microphone charging case 30 further includes a circuit board 35; the circuit board 35 is disposed in the accommodation cavity 311 of the case body 31. Among them, the circuit board 35 serves as an electrical connection member of the wireless microphone charging case 30 and is used to realize the electrical connection between at least one of the transmitter 10, the receiver 20, and the 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 rigid-flex circuit board 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, and the reinforcing plate is disposed on one side of the flexible circuit board 35 to provide support for the flexible circuit board 35.

[0057] Multiple groups of indicator lights 33 are mounted on the circuit board 35 and are electrically connected to the circuit board 35. The light emitting surfaces of each group of indicator lights 33 (that is, the light emitting surfaces of the lamp beads introduced above) are in contact with the side walls of the corresponding mounting body 342. In this way, the light projected by each group of indicator lights 33 can be transmitted from the indicator light 33 to the corresponding mounting body 342 in the least loss, then guided from the mounting body 342 to the corresponding light guide unit 343, and finally pass through the corresponding mounting position 312 and be acquired by the user's eyes.

By designing the partition member 36 in the gap formed between two adjacent mounting bodies 342, the partition member 36 can further effectively block the light projected from two adjacent indicator lights 33, so as to further effectively improve the light crosstalk problem between two adjacent indicator lights 33 and improve the indication accuracy of the indicator lights 33.

[0059] As Figure 3 and Figure 7 As shown, the wireless microphone charging bin 30 further includes a support base 37 for mounting a circuit board 35; the support base 37 is located in the accommodation cavity 311 of the bin body 31 and is connected to the bin body 31; the support base 37 has an accommodation groove 371; each accommodation groove 371 is used to avoid a group of indicator lights 33, and the plane where the notch of the accommodation groove 371 is located fits the side wall of the mounting body 342.

[0060] Among them, the support base 37 serves as another bracket of the wireless microphone charging bin 30 to carry structural components such as the circuit board 35 and the power supply 38. Here, the specific preparation material of the support base 37 is not limited, and designers can make reasonable selections according to actual needs; for example, the preparation material of the support base 37 can be, but is not limited to, one of plastics or plastics; such raw materials are widely sourced and easy to obtain, and can effectively reduce the cost of the wireless microphone charging bin 30. It should be noted that the preparation materials of the support base 37, the charging base 32 and the bin body 31 can be the same or different.

Here, the specific connection method between the support base 37 and the bin body 31 is not limited, and designers can make reasonable designs according to actual needs; for example, the support base 37 can be, but is not limited to, detachably connected to the bin body 31 by at least one of screwing, clamping or plugging; for another example, the support base 37 can also be, but is not limited to, non-detachably connected to the bin body 31 by riveting or gluing.

[0062] The circuit board 35 is installed on the support base 37. The specific connection method between the circuit board 35 and the support base 37 is not limited herein, and the designer can make a reasonable design according to actual needs; for example, the circuit board 35 can be detachably connected to the support base 37 by at least one of screwing, clamping or plugging, etc.; or for another example, the circuit board 35 can also be non-detachably connected to the support base 37 by gluing or riveting, etc.

[0063] By designing a receiving groove 371 for avoiding the indicator light 33 on the circuit board 35 and making the plane where the notch of the receiving groove 371 is located fit with the side wall of the mounting body 342, so that the indicator light 33 is covered in the receiving groove 371, the mounting body 342 can centrally guide the light projected by the indicator light 33, and the problem of light crosstalk between two adjacent indicator lights 33 can be further effectively improved.
