Description

Technical Field

[0001] This application relates to the field of microphone technology, and more particularly to a desktop microphone. Background Technology

[0002] A desktop microphone is a type of microphone primarily designed for use on a desktop. Unlike handheld, lavalier, or headset microphones, it typically doesn't require being held or worn. Instead, it's stably positioned on the desktop using a base, stand, or cantilever to capture audio signals. Desktop microphones are widely used in offices, recording studios, and live streaming environments, making them a popular choice among users.

[0003] Desktop microphones on the market, while serving the function of sound pickup and transmission, can also emit light in their pickup chambers to create a lighting atmosphere. However, due to their inherent structural design, desktop microphones often suffer from uneven brightness distribution in their pickup chambers. Therefore, improving the uniformity of brightness in the pickup chambers of desktop microphones has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a desktop microphone that can solve the problem of uneven brightness distribution in the pickup cavity of desktop microphones due to their own structural design.

[0005] This application provides a desktop microphone. The desktop microphone includes a housing assembly, a pickup assembly, and a light-emitting assembly. The housing assembly includes a lower shell with a first receiving cavity, a mounting bracket at least partially located within the first receiving cavity, and an upper shell with a second receiving cavity. The upper shell is connected to the lower shell via the mounting bracket. The pickup assembly includes a microphone, which is mounted on the mounting bracket and at least partially located within the second receiving cavity of the upper shell. The light-emitting assembly includes a first light-emitting unit and a second light-emitting unit. At least a portion of the first light-emitting unit is located within the second receiving cavity of the upper shell and is configured to emit light that can pass through the upper shell. At least a portion of the second light-emitting unit is located within the second receiving cavity of the upper shell and is configured to emit light that can pass through the upper shell. The first light-emitting unit is further away from the lower shell than the second light-emitting unit.

[0006] Based on the embodiments of this application, the desktop microphone, by designing a first light-emitting unit and a second light-emitting unit, and positioning the first light-emitting unit further away from the lower shell than the second light-emitting unit, allows at least a portion of the second receiving cavity used to house the microphone head to serve as the pickup cavity of the desktop microphone, enabling light emission from both sides and resulting in a more uniform brightness distribution within the pickup cavity. By adjusting the illumination states of the first and second light-emitting units, the lighting effect of the desktop microphone's pickup cavity can be altered. This allows the desktop microphone to not only perform sound pickup and transmission but also allow the user or others to observe the lighting effect created by the combined action of the first and second light-emitting units, further enhancing the lighting atmosphere.

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0011] A desktop microphone is a type of microphone primarily designed for use on a desktop. Unlike handheld, lavalier, or headset microphones, it typically doesn't require being held or worn. Instead, it's stably positioned on the desktop using a base, stand, or cantilever to capture audio signals. Desktop microphones are widely used in offices, recording studios, and live streaming environments, making them a popular choice among users.

[0012] Desktop microphones on the market, while serving the function of sound pickup and transmission, can also emit light to create a lighting atmosphere within their pickup cavity. However, desktop microphones in this technology typically only have a single light-emitting unit within the pickup cavity. This results in the area of ​​the pickup cavity near the light-emitting unit being brighter, while the area farther away from the light-emitting unit is dimmer, leading to uneven brightness distribution within the pickup cavity. Therefore, improving the uniformity of brightness within the pickup cavity of desktop microphones has become an urgent problem to be solved.

[0013] Please refer to Figures 1-4 As shown, in order to solve the above problems, this application proposes a desktop microphone 1 that can emit light from both sides, making the brightness distribution of the pickup cavity of the desktop microphone 1 more uniform.

[0014] The desktop microphone 1 includes a housing assembly 10, a pickup assembly 40, and a light-emitting assembly 30. The housing assembly 10 includes a lower housing 11 having a first receiving cavity 11a, a mounting bracket 12 at least partially located within the first receiving cavity 11a, and an upper housing 13 having a second receiving cavity 13a, the upper housing 13 being connected to the lower housing 11 via the mounting bracket 12. The pickup assembly 40 includes a microphone 41, which is mounted on the mounting bracket 12 and at least partially located within the second receiving cavity 13a of the upper housing 13. The light-emitting assembly 30 includes a first light-emitting unit 32 and a second light-emitting unit 33. At least a portion of the first light-emitting unit 32 is located within the second receiving cavity 13a of the upper housing 13, and the first light-emitting unit 32 is configured to emit light that can pass through the upper housing 13. At least a portion of the second light-emitting unit 33 is located within the second receiving cavity 13a of the upper housing 13, and the second light-emitting unit 33 is configured to emit light that can pass through the upper housing 13. The first light-emitting unit 32 is located further away from the lower housing 11 than the second light-emitting unit 33.

[0015] The following combination Figures 1-21 The specific structure of the desktop microphone 1 will be described in detail.

[0016] like Figures 1-4 As shown, the desktop microphone 1 includes a housing assembly 10, a pickup assembly 40, and a light-emitting assembly 30.

[0017] The housing assembly 10 serves as the housing of the desktop microphone 1, and includes a lower housing 11, a mounting bracket 12, and an upper housing 13.

[0018] The lower shell 11 is one of the shells of the shell assembly 10. The lower shell 11 has a first receiving cavity 11a, which is the hollow area inside the lower shell 11.

[0019] Mounting bracket 12 serves as a support for housing assembly 10, with at least a portion of mounting bracket 12 located within the first receiving cavity 11a of lower housing 11. For example, the entire mounting bracket 12 may be located within the first receiving cavity 11a of lower housing 11, or a portion of mounting bracket 12 may be located within the first receiving cavity 11a of lower housing 11, with the remaining portion of mounting bracket 12 extending out of the first receiving cavity 11a of lower housing 11 via the opening of the first receiving cavity 11a.

[0020] The upper shell 13 serves as another shell of the shell assembly 10. The upper shell 13 has a second receiving cavity 13a, at least a portion of which serves as the pickup cavity for the desktop microphone 1 to accommodate the pickup assembly 40. When a portion of the mounting bracket 12 is located within the first receiving cavity 11a of the lower shell 11, the portion of the mounting bracket 12 extending out of the first receiving cavity 11a of the lower shell 11 via the opening of the first receiving cavity 11a is located within the second receiving cavity 13a of the upper shell 13.

[0021] The upper shell 13 is connected to the lower shell 11 via the mounting bracket 12. That is, the mounting bracket 12 serves as an intermediate connecting structure between the upper shell 13 and the lower shell 11 to assemble them together. The specific connection method between the upper shell 13 (or lower shell 11) and the mounting bracket 12 is not limited here, and designers can make reasonable designs according to actual needs. For example, the upper shell 13 (or lower shell 11) can be detachably and fixedly connected to the mounting bracket 12 by at least one of the following methods: screw connection, snap connection, or plug connection. Alternatively, the upper shell 13 (or lower shell 11) can also be non-detachably and fixedly connected to the mounting bracket 12 by means of adhesive bonding or riveting.

[0022] like Figures 1-4 As shown, the pickup component 40 serves as the pickup module of the desktop microphone 1. The pickup component 40 includes a microphone 41, which is used to collect audio signals.

[0023] The microphone 41 is mounted on the mounting bracket 12. The specific installation method between the microphone 41 and the mounting bracket 12 is not limited here. Designers can make reasonable designs according to actual needs. For example, the microphone 41 can be detachably and fixedly connected to the mounting bracket 12 by at least one of the following methods: screw connection, snap connection or plug connection. Alternatively, the microphone 41 can also be non-detachably and fixedly connected to the mounting bracket 12 by adhesive connection or riveting.

[0024] At least a portion of the microphone 41 is located within the second receiving cavity 13a of the upper shell 13; for example, the entire microphone 41 may be located within the second receiving cavity 13a of the upper shell 13, or a portion of the microphone 41 may be located within the second receiving cavity 13a of the upper shell 13, with the remaining portion of the microphone 41 extending outside the second receiving cavity 13a of the upper shell 13 via the opening of the second receiving cavity 13a (e.g., the bottom of the microphone 41 may be located within the first receiving cavity 11a of the lower shell 11). In this embodiment, the entire microphone 41 is located within the second receiving cavity 13a of the upper shell 13, so that at least a portion of the second receiving cavity 13a of the upper shell 13 serves as the pickup cavity of the desktop microphone 1.

[0025] like Figures 1-4 As shown, the light-emitting component 30 serves as the light-emitting module of the desktop microphone 1, and the light-emitting component 30 includes a first light-emitting unit 32 and a second light-emitting unit 33.

[0026] At least a portion of the first light-emitting unit 32 is located within the second receiving cavity 13a of the upper shell 13. The first light-emitting unit 32 is configured such that the emitted light can pass through the upper shell 13. It is understood that whether the entire first light-emitting unit 32 is located within the second receiving cavity 13a of the upper shell 13 or only a portion of the first light-emitting unit 32 is located within the second receiving cavity 13a of the upper shell 13, the light emitted by the first light-emitting unit 32 can propagate within the second receiving cavity 13a of the upper shell 13. At least a portion of the second receiving cavity 13a used to accommodate the microphone head 41 serves as the pickup cavity of the desktop microphone 1 and can emit light. This allows the desktop microphone 1 to not only perform sound pickup and transmission but also allow the user or others to observe the lighting effect created by the first light-emitting unit 32, creating a cool lighting atmosphere and enhancing the user experience.

[0027] At least a portion of the second light-emitting unit 33 is located within the second receiving cavity 13a of the upper shell 13. The second light-emitting unit 33 is configured such that the emitted light can pass through the upper shell 13. It is understood that whether the entire second light-emitting unit 33 is located within the second receiving cavity 13a of the upper shell 13 or only a portion of the second light-emitting unit 33 is located within the second receiving cavity 13a of the upper shell 13, the light emitted by the second light-emitting unit 33 can propagate within the second receiving cavity 13a of the upper shell 13. At least a portion of the second receiving cavity 13a used to accommodate the microphone head 41 serves as the pickup cavity of the desktop microphone 1 and can emit light. This allows the desktop microphone 1 to not only perform sound pickup and transmission but also allow the user or others to observe the lighting effect created by the second light-emitting unit 33, creating a cool lighting atmosphere and enhancing the user experience.

[0028] The first light-emitting unit 32 is further away from the lower shell 11 than the second light-emitting unit 33. For example, the first light-emitting unit 32 can be located on the side of the top seat 1311 (described below) of the upper shell 13, and the second light-emitting unit 33 can be located on the side of the base 1313 (described below) of the upper shell 13. At least part of the second receiving cavity 13a used to accommodate the microphone head 41 serves as the pickup cavity of the desktop microphone 1 to achieve light emission from both sides, thereby making the brightness distribution of the pickup cavity of the desktop microphone 1 more uniform.

[0029] By adjusting the illumination states of the first light-emitting unit 32 and the second light-emitting unit 33, the lighting effect of the pickup cavity of the desktop microphone 1 can be changed. This allows the desktop microphone 1 to not only perform its sound pickup and transmission function but also allow the user or others to observe the lighting effect created by the combined action of the first and second light-emitting units 32, further enhancing the lighting atmosphere. It should be noted that when the pickup cavity of the desktop microphone 1 is illuminated, the illumination states of the first and second light-emitting units 32 can be the same or different.

[0030] Based on the desktop microphone 1 in this embodiment, by designing a first light-emitting unit 32 and a second light-emitting unit 33, and positioning the first light-emitting unit 32 further away from the lower shell 11 than the second light-emitting unit 33, at least a portion of the second receiving cavity 13a used to accommodate the microphone head 41 can achieve light emission from both sides as the pickup cavity of the desktop microphone 1, making the brightness distribution of the pickup cavity of the desktop microphone 1 more uniform. By adjusting the lighting state of the first light-emitting unit 32 and the second light-emitting unit 33, the lighting effect of the pickup cavity of the desktop microphone 1 can be changed, so that while the desktop microphone 1 has the function of sound pickup and transmission, the user or others can also observe the lighting effect created by the combined action of the first light-emitting unit 32 and the second light-emitting unit 33, further enhancing the lighting atmosphere.

[0031] like Figure 4 and Figure 5 As shown, the upper shell 13 includes a base 1313, a blowout preventer 1312, a top seat 1311, and a cover 1314. The base 1313 is closer to the lower shell 11 than the top seat 1311. The base 1313, the blowout preventer 1312, and the top seat 1311 are connected to enclose and form the aforementioned second receiving cavity 13a. The base 1313 is connected to the mounting bracket 12. The top seat 1311 has a receiving groove 1311a on the side opposite to the lower shell 11. The cover 1314 is connected to the top seat 1311 to cover the opening of the receiving groove 1311a. The bottom surface of the receiving groove 1311a has a clearance hole 1311d that communicates with the second receiving cavity 13a.

[0032] The base 1313 can be detachably and fixedly connected to the mounting bracket 12 by at least one of the following methods: screwing, snap-fitting, or plugging. The spray guard 1312 can be detachably and fixedly connected to the base 1313 (or the top seat 1311) by at least one of the following methods: screwing, snap-fitting, or plugging. The cover 1314 can be detachably and fixedly connected to the top seat 1311 by at least one of the following methods: screwing, snap-fitting, or plugging. Specifically, in this embodiment, the groove wall of the receiving groove 1311a of the top seat 1311 is provided with a snap-fitting flange 1311c; the cover 1314 includes a top wall 1314a and a side wall 1314b circumferentially connected to the top wall 1314a. The side wall 1314b is provided with a snap-fit ​​1314c, which is used to engage with the snap-fitting flange 1311c to position the cover 1314 on the top seat 1311. The snap-fit ​​flange 1311c can be integrally formed with the top seat 1311 by injection molding or 3D printing, but not limited to. By designing the snap-fit ​​flange 1311c and the bayonet 1314c, the snap-fit ​​flange 1311c and the bayonet 1314c engage to achieve a relatively fixed position between the cover 1314 and the top seat 1311. The structure is simple and easy to implement.

[0033] like Figure 4 and Figure 5 As shown, the desktop microphone 1 also includes a control component 20, which includes a first circuit board 21 located within a receiving slot 1311a and connected to a top mount 1311. A first light-emitting unit 32 passes through a clearance hole 1311d and is electrically connected to the first circuit board 21. The first light-emitting unit 32 and the second light-emitting unit 33 are configured such that the light emitted can pass through a pop filter 1312.

[0034] The control component 20 serves as the control module for the desktop microphone 1. The control component 20 includes a first circuit board 21, which can be a rigid circuit board, a flexible circuit board, or a combination of both. The first circuit board 21 is connected to the top mount 1311. The specific connection method between the first circuit board 21 and the top mount 1311 is not limited; designers can design it appropriately according to actual needs. For example, the first circuit board 21 can be detachably and fixedly connected to the top mount 1311 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the first circuit board 21 can be non-detachably and fixedly connected to the top mount 1311 by adhesive bonding or riveting. It should be noted that when the first circuit board 21 is a flexible circuit board, the control component 20 may also include a reinforcing plate, which is disposed on one side of the flexible circuit board to provide support.

[0035] The pop filter 1312 is a mesh with many holes. The light emitted by the first light-emitting unit 32 and the second light-emitting unit 33 can pass through the holes of the pop filter 1312 and be projected out so that it can be observed by the user's eyes.

[0036] Specifically, the detailed design of the clearance hole 1311d and the first light-emitting unit 32 may include, but is not limited to, the following cases.

[0037] In the first case, the clearance hole 1311d is located in the middle of the bottom surface of the receiving groove 1311a. This places the first light-emitting unit 32, through which the clearance hole 1311d is provided, in the middle of the bottom surface of the receiving groove 1311a, thereby bringing the first light-emitting unit 32 as close as possible to the central region of the top seat 1311.

[0038] In the second scenario, the first light-emitting unit 32 includes a plurality of second RGB LED beads 321 electrically connected to the first circuit board 21. The second RGB LED beads 321 are used to project multi-color light, providing multiple colors of light (such as red, orange, yellow, green, cyan, blue, and purple). The second RGB LED beads 321 include a red light chip, a green light chip, and a blue light chip. By independently controlling the brightness of these three chips and mixing the light they project together, different colors of light are obtained.

[0039] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the mounting bracket 12 includes a cylinder 121, a support plate 122, and a side plate 123. The microphone 41 is mounted on the cylinder 121; the support plate 122 has an annular structure that fits around the outer periphery of the cylinder 121, and the inner annular surface of the support plate 122 is connected to the outer wall surface of the cylinder 121; the side plate 123 extends along a direction parallel to the cylinder axis of the cylinder 121, one end of the side plate 123 is connected to the side of the support plate 122 away from the cylinder 121, and the other end of the side plate 123 is connected to the lower shell 11.

[0040] The cylinder 121, the support plate 122, and the side plate 123 can be formed into a single structure by injection molding or 3D printing, but are not limited to this method. The specific connection method between the microphone 41 and the cylinder 121 is not limited here; designers can design it reasonably according to actual needs. For example, the microphone 41 can be detachably connected to the cylinder 121 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the microphone 41 can be non-detachably connected to the cylinder 121 by riveting or gluing, but are not limited to this method.

[0041] The control component 20 also includes a third circuit board 26, which is disposed on the support plate 122 and has an annular structure sleeved on the outer periphery of the cylinder 121.

[0042] The third circuit board 26 is annular and is fitted around the outer periphery of the cylinder 121. The specific connection method between the third circuit board 26 and the carrier plate 122 is not limited, and the designer can make a reasonable design according to the actual needs. For example, the third circuit board 26 can be detachably fixed to the carrier plate 122 by at least one of the following methods: screw connection, snap connection, or plug connection. Alternatively, the third circuit board 26 can be non-detachably fixed to the carrier plate 122 by riveting or gluing.

[0043] The second light-emitting unit 33 includes a plurality of third RGB LED beads 331 electrically connected to the third circuit board 26. The plurality of third RGB LED beads 331 are arranged at intervals around the cylindrical axis of the cylinder 121 on the side of the third circuit board 26 facing away from the support plate 122, and the plurality of third RGB LED beads 331 are disposed adjacent to the inner edge of the third circuit board 26.

[0044] The third RGB LED bead 331 is used to project multi-color light, providing multiple colors of light (such as red, orange, yellow, green, cyan, blue, and purple). The third RGB LED bead 331 includes a red light chip, a green light chip, and a blue light chip. By independently controlling the brightness of these three chips and mixing the light they project together, different colors of light can be obtained.

[0045] By designing multiple third RGB LED beads 331 to be positioned near the inner edge of the third circuit board 26, the multiple third RGB LED beads 331 are brought together as close as possible to the cylindrical axis of the cylinder 121, such as... Figure 9 As shown, the light from two adjacent third RGB LED beads 331 striking the light-transmitting element 42 (described below) of the pickup assembly 40 overlaps as much as possible, thus reducing the formation of dark spots. It is understandable that, as... Figure 10 As shown, if the multiple third RGB LED beads 331 are far from the inner edge of the third circuit board 26 (that is, close to the outer edge of the third circuit board 26), the third RGB LED beads 331 are close to the light-transmitting element 42 of the pickup component 40. The light rays from two adjacent third RGB LED beads 331 hitting the light-transmitting element 42 of the pickup component 40 do not overlap, forming alternating bright and dark light areas on the light-transmitting element 42 of the pickup component 40. The darker areas form the aforementioned black spots.

[0046] Of course, the multiple second RGB LED beads 321 are also converged as much as possible towards the cylindrical axis of the cylinder 121, so that the light from two adjacent second RGB LED beads 321 hitting the light-transmitting element 42 of the pickup assembly 40 can overlap as much as possible, thus reducing the generation of black spots. In some other embodiments, the third circuit board 26 can also be a non-ring structure (e.g., circular). In this case, the mounting bracket 12 has a hollow structure (such as a hollow frame structure formed by multiple ribs). In this case, the third circuit board 26 is located within the hollow area 13d of the mounting bracket 12, and the multiple third RGB LED beads 331 are concentrated in the middle of the third circuit board 26. This makes the multiple third RGB LED beads 331 converge as much as possible inward, which can effectively reduce the generation of black spots. In some other embodiments, the third circuit board 26 may also have a non-circular structure (e.g., circular). In this case, the mounting bracket 12 is made of a light-transmitting material, and the third circuit board 26 is located in the cavity of the mounting bracket 12. Multiple third RGB LED beads 331 are concentrated in the middle of the third circuit board 26. The light-transmitting mounting bracket 12 will not block the light emitted by the multiple third RGB LED beads 331. This allows the multiple third RGB LED beads 331 to be gathered as much as possible inward, which can effectively reduce the generation of black spots.

[0047] like Figures 2-4 and Figures 11-13 As shown, the pickup assembly 40 also includes a light-transmitting element 42, at least a portion of which is located within the second receiving cavity 13a of the upper housing 13. The light-transmitting element 42 is arranged around the microphone 41. The first light-emitting unit 32 and the second light-emitting unit 33 are configured such that the emitted light can pass through the light-transmitting element 42 and the pop filter 1312 in sequence.

[0048] The light-transmitting element 42 is light-transmitting and can be either a light-transmitting sponge 421 or a light-transmitting plate. The light-transmitting element 42 has a cylindrical structure surrounding the microphone 41. The specific connection between the light-transmitting element 42 and the upper shell 13 is not limited here; designers can design it reasonably according to actual needs. For example, the base 1313 has a slot on the side near the top seat 1311, the bottom end of the light-transmitting element 42 is inserted into the slot, and the outer annular surface of the light-transmitting element 42 has a groove, in which the connector 1315 of the upper shell 13 (described below) is embedded. The aforementioned blowout screen 1312 is located around the light-transmitting element 42.

[0049] The light emitted by the first light-emitting unit 32 and the second light-emitting unit 33 can pass through the light-transmitting element 42 and the pop filter 1312. At least a portion of the second receiving cavity 13a used to accommodate the microphone head 41, which serves as the pickup cavity of the desktop microphone 1, can emit light. This allows the desktop microphone 1 to not only pick up and transmit sound, but also to be observed by the user or others, creating a lighting effect through the combined action of the first light-emitting unit 32 and the second light-emitting unit 33. This creates a cool lighting atmosphere, enhances the ambiance, and improves the user experience.

[0050] The upper shell 13 also includes two connectors 1315, which are located between the base 1313 and the top seat 1311. Both ends of the connectors 1315 are connected to the base 1313 and the top seat 1311. The base 1313, the two connectors 1315, and the top seat 1311 enclose two hollow areas 13d that communicate with the second receiving cavity 13a. There are two blowout preventers 1312, each corresponding to one of the two hollow areas 13d, and each blowout preventer 1312 is connected to at least one of the base 1313 and the top seat 1311. The connectors 1315 are elongated columnar structures. The base 1313, connectors 1315, and top seat 1311 can be, but are not limited to, formed as a single unit through injection molding or 3D printing. By designing the connector 1315, the connector 1315 serves two purposes: firstly, it acts as a connector to link the base 1313 and the top seat 1311 into a whole; secondly, it acts as a reinforcing rib to enhance the overall structural strength of the upper shell 13. The base 1313, the two connectors 1315, and the top seat 1311 enclose two hollow areas 13d that communicate with the second receiving cavity 13a. The light emitted by the first light-emitting unit 32 and the second light-emitting unit 33 passes through the light-transmitting element 42 and then exits from the hollow area 13d and the corresponding blowout preventer 1312 to the outside of the second receiving cavity 13a of the upper shell 13.

[0051] like Figure 14 As shown, the desktop microphone 1 also includes a support component 70, which includes a first bracket 71, a second bracket 72, and an elastic body 73. The first bracket 71 is disposed on the desktop, and the second bracket 72 is connected to the first bracket 71. The second bracket 72 has an annular structure that fits around the lower shell 11, and the lower shell 11 is connected to the second bracket 72 via the elastic body 73.

[0052] The first bracket 71 is set on the desktop, and its specific form can be varied. For example, when there is no connection between the first bracket 71 and the desktop, the first bracket 71 may include a support base connected to the second bracket 72. In this case, the entire desktop microphone 1 can be placed stably on the desktop directly through the support base. Alternatively, the first bracket 71 may also include a support tripod connected to the second bracket 72. In this case, the entire desktop microphone 1 can be stably supported on the desktop directly through the support tripod. As another example, when there is a connection between the first bracket 71 and the desktop, the first bracket 71 may include a support cantilever bracket. One end of the support cantilever bracket is connected to the second bracket 72, and the other end of the support cantilever bracket can be positioned on the desktop by means of clamping or screw locking, but not limited to clamping. Alternatively, the first bracket 71 may also be positioned on the desktop by negative pressure adsorption (in this case, the first bracket 71 includes a suction cup) or magnetic adsorption (in this case, the first bracket 71 includes a magnet).

[0053] The second bracket 72 can be fixedly connected to the first bracket 71, in which case the angle between the second bracket 72 and the first bracket 71 is not adjustable; the second bracket 72 can also be rotatably connected to the first bracket 71, in which case the angle between the second bracket 72 and the first bracket 71 is adjustable, and the user can rotate the second bracket 72 to a suitable angle according to actual needs. The support assembly 70 also includes a locking member 74, which is used to lock the second bracket 72 to the first bracket 71 after the angle of the second bracket 72 relative to the first bracket 71 is fixed, so that the second bracket 72 and the first bracket 71 cannot rotate relative to each other. The locking member 74 can be, but is not limited to, a locking screw or a locking pin.

[0054] The elastomer 73 is designed to undergo elastic deformation under stress, thereby providing cushioning and shock absorption for the outer shell. The outer circumferential surface of the lower shell 11 is provided with multiple first latches 11c, and the inner annular surface of the second bracket 72 is provided with multiple second latches 72a. There are multiple elastomers 73, each of which includes an elastic hook 731. One end of the elastic hook 731 engages with two adjacent first latches 11c, and the other end of the elastic hook 731 engages with a corresponding second latch 72a.

[0055] like Figures 1-3 , Figure 15 and Figure 16As shown, the control assembly 20 also includes a second circuit board 25, which is mounted on the mounting bracket 12 and at least partially located within the first receiving cavity 11a of the lower housing 11. At least a portion of the lower housing 11 is made of an insulating non-metallic material. The desktop microphone 1 also includes a wireless communication device 50 for connection to a terminal, and a wireless module 60. The wireless module 60 is electrically connected to the second circuit board 25 and is used for wireless communication with the wireless communication device 50. By designing the wireless module 60, which wirelessly connects to the terminal via the wireless communication device 50, audio signals are transmitted wirelessly, resulting in a wireless desktop microphone 1 and reducing the use of cables.

[0056] The second circuit board 25 may be detachably fixedly connected to the mounting bracket 12 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the second circuit board 25 may be non-detachably fixedly connected to the mounting bracket 12 by adhesive bonding or riveting. The second circuit board 25 is electrically connected to the first circuit board 21 and also electrically connected to the third circuit board 26.

[0057] At least a portion of the lower shell 11 can be made of insulating non-metallic materials such as plastic, ceramic, or wood. The areas of the lower shell 11 made of insulating non-metallic material form an unshielded area. This unshielded area does not shield the transmission of audio signals, allowing the audio signal to pass through the unshielded area and be transmitted wirelessly from the side where the wireless module 60 is located to the wireless communication device 50. The audio signal (which may be a processed audio signal obtained from terminal processing) can also pass through the unshielded area and be transmitted wirelessly from the side where the wireless communication device 50 is located to the wireless module 60, reducing or even eliminating interference, ensuring the sound quality of the audio signal, improving the stability of audio signal transmission, and preventing signal interruption. In this embodiment, the lower shell 11 is entirely made of insulating non-metallic material, which reduces the processing difficulty and cost of the lower shell 11.

[0058] The wireless communication device 50 is used to connect to a terminal, which may include, but is not limited to, tablet computers, laptops, desktop computers, ultra-mobile personal computers (UMPCs), netbooks, mobile phones, etc.

[0059] The wireless module 60 serves as the wireless communication terminal of the desktop microphone 1. It wirelessly connects to the terminal via the wireless communication device 50 to transmit audio signals wirelessly. The wireless module 60 is electrically connected to the second circuit board 25, enabling the audio signal to be wirelessly transmitted from the wireless module 60 to the wireless communication device 50, and then from the wireless communication device 50 to the terminal. Alternatively, the audio signal (which may be a processed audio signal obtained from the terminal's processing) can also be wirelessly transmitted from the wireless communication device 50 to the wireless module 60, and then from the wireless module 60 to the controller 23 of the control component 20 (described below).

[0060] The microphone 41 collects audio signals and sends them to the controller 23 of the control component 20. The controller 23 of the control component 20 sends the audio signals to the wireless module 60. The wireless module 60 sends the audio signals to the wireless communication device 50 via wireless transmission. The wireless communication device 50 sends the audio signals to the terminal, enabling the terminal to play audio in real time based on the audio signals.

[0061] It should be noted that if an external headset is connected to the headphone jack of desktop microphone 1, the user can use the external headset to monitor the audio signal in real time. The external headset is only used for monitoring the audio signal, and is with the user's permission, and does not involve any other personal privacy data.

[0062] Specifically, the wireless module 60 includes a ceramic dielectric antenna or a metal antenna electrically connected to the second circuit board 25. Ceramic dielectric antennas are readily available and inexpensive, while metal antennas can be made of copper or aluminum. The specific antenna structure for the ceramic dielectric antenna and the metal antenna is not limited here; designers can design them appropriately according to actual needs, as long as the ceramic dielectric antenna and the metal antenna can achieve good transmission and reception of audio signals.

[0063] The desktop microphone 1 also includes a battery (not shown) electrically connected to the second circuit board 25, which is located inside the cavity of the housing 121 of the mounting bracket 12. The battery provides the power required for the desktop microphone 1 to operate, eliminating the limitations of cables and providing an energy guarantee for high-quality audio signals and reliable wireless transmission.

[0064] like Figures 6-8 , Figure 11 and Figure 12 As shown, the control component 20 also includes a gain adjustment switch 27, which is disposed on the lower housing 11 and electrically connected to the second circuit board 25. The gain adjustment switch 27 is used to control the sensitivity of the microphone 41 of the desktop microphone 1 in picking up audio signals, and also to adjust the volume of the audio signal to obtain a clearer audio signal.

[0065] Specifically, the lower shell 11 has an opening 11b communicating with the first receiving cavity 11a on the side opposite to the upper shell 13; the gain adjustment switch 27 includes a potentiometer, which is positioned corresponding to the opening 11b and electrically connected to the second circuit board 25; the housing assembly 10 also includes a rotating cover 14, which is located on the side of the lower shell 11 opposite to the upper shell 13 and connected to the knob of the potentiometer. The potentiometer, commonly known as a "variable resistor," outputs a continuous voltage signal. By rotating the rotating cover 14, the user can change the position of the potentiometer's brush (sliding contact) on the potentiometer's resistance track, thereby achieving gain adjustment. By designing the rotating cover 14 at the bottom of the lower shell 11, compared to designing the rotating cover 14 on the side of the lower shell 11, it is possible to effectively avoid the interference of the second bracket 72 and the elastic body 73 on the rotating cover 14, ensuring the reasonable spatial distribution of each component, and at the same time reducing the overall volume of the desktop microphone 1 (if the rotating cover 14 is designed on the side of the lower shell 11, the volume of the lower shell 11 needs to be increased so that the second bracket 72 and the elastic body 73 do not interfere with the rotating cover 14); in addition, it can also reduce the possibility of the user accidentally touching the rotating cover 14.

[0066] Alternatively, the lower housing 11 has an opening 11b communicating with the first receiving cavity 11a on the side opposite to the upper housing 13; the gain adjustment switch 27 includes an encoder, which is positioned corresponding to the opening 11b and electrically connected to the second circuit board 25; the housing assembly 10 also includes a rotating cover 14, which is located on the side of the lower housing 11 opposite to the upper housing 13 and connected to the encoder's knob. The encoder is a sensor that converts rotational or linear displacement into a series of digital pulses, outputting digital pulses representing direction and step count. By rotating the rotating cover 14, the user rotates the knob of the encoder connected to it. The encoder's grid-patterned disc alternately blocks light (or switches contacts on and off), generating two square wave pulses with a 90° phase difference. The distance of rotation is calculated by counting the number of pulses, thus achieving gain adjustment. By designing the rotating cover 14 at the bottom of the lower shell 11, compared to designing the rotating cover 14 on the side of the lower shell 11, it is possible to effectively avoid the interference of the second bracket 72 and the elastic body 73 on the rotating cover 14, ensuring the reasonable spatial distribution of each component, and at the same time reducing the overall volume of the desktop microphone 1 (if the rotating cover 14 is designed on the side of the lower shell 11, the volume of the lower shell 11 needs to be increased so that the second bracket 72 and the elastic body 73 do not interfere with the rotating cover 14); in addition, it can also reduce the possibility of the user accidentally touching the rotating cover 14.

[0067] like Figure 5 , Figure 15 and Figure 16As shown, the upper shell 13 (specifically the cover 1314 described above) has a first touch area 13b on the side opposite to the lower shell 11. The control component 20 also includes a first detection element 22, which is disposed corresponding to the first touch area 13b. That is, the orthographic projection of the first detection element 22 onto the plane of the first touch area 13b falls within the first touch area 13b. The first detection element 22 is electrically connected to the first circuit board 21 described above.

[0068] The first detection element 22 is used to detect when a user's finger touches or approaches the first touch area 13b. For example, it can be a capacitive touchscreen, utilizing the human body's electric field sensing. The user's finger can touch or approach (within a certain distance) the first touch area 13b, and is detected by changing the capacitance value of the sensor surface. Alternatively, it can be an infrared touchscreen, using an infrared emitter and receiver to form a grid. The user's finger can touch or approach (within a certain distance) the first touch area 13b, and is detected by blocking or reflecting some of the infrared light. Another example is a physical switch-type touchscreen. In this case, the control component 20 can also include a first switch. The upper shell 13 has a first opening on the side opposite to the lower shell 11 for the first switch to pass through. The first opening serves as the first touch area 13b. The user's finger is detected by directly contacting the first switch and applying force to it (at this time, the user's finger does not directly touch the first opening that serves as the first touch area 13b, but rather approaches it).

[0069] like Figure 5 , Figure 15 and Figure 16 As shown, the light-emitting component 30 also includes an indicator light 31, which is electrically connected to the first circuit board 21 and configured to emit light that can pass through the upper housing 13. It is understood that the desktop microphone 1 has various preset functions such as mute, noise reduction, and stereo. The indicator light 31 has multiple different lighting states, each corresponding to a preset function of the desktop microphone 1. Thus, the user can determine the current preset function of the desktop microphone 1 by observing the current lighting state of the indicator light 31.

[0070] The first detection element 22 is used to send a first detection signal to the controller 23 of the control component 20 when the user's finger touches or approaches the first touch area 13b. The controller 23 of the control component 20 then controls the indicator light 31 to light up according to a preset mode based on the first detection signal. The preset mode may include, but is not limited to, the indicator light 31 being constantly lit, the indicator light 31 flashing, and the indicator light 31 displaying different colors.

[0071] Taking the desktop microphone 1 with mute and noise reduction functions as an example, when a user touches or approaches the first touch area 13b, the first detection element 22 generates a first detection signal and sends the first detection signal to the controller 23 of the control component 20. The controller 23 of the control component 20 controls the indicator light 31 to be constantly lit according to the first detection signal. The light emitted by the indicator light 31 can pass through the upper shell 13. The user can judge that the desktop microphone 1 can be in the mute function at this time by the constantly lit light effect of the indicator light 31. When a user touches or approaches the first touch area 13b, the first detection element 22 generates a first detection signal and sends the first detection signal to the controller 23 of the control component 20. The controller 23 of the control component 20 controls the indicator light 31 to be flashing according to the first detection signal. The light emitted by the indicator light 31 can pass through the upper shell 13. The user can judge that the desktop microphone 1 can be in the noise reduction function at this time by the flashing light effect of the indicator light 31. Alternatively, taking a desktop microphone 1 with mute and noise reduction functions as an example, when a user touches or approaches the first touch area 13b, the first detection element 22 generates a first detection signal and sends it to the controller 23 of the control component 20. The controller 23 of the control component 20 controls the indicator light 31 to turn red according to the first detection signal. The red light emitted by the indicator light 31 can pass through the upper shell 13. The user can judge that the desktop microphone 1 can be in the mute function at this time by observing the red light effect of the indicator light 31. When a user touches or approaches the first touch area 13b, the first detection element 22 generates a first detection signal and sends it to the controller 23 of the control component 20. The controller 23 of the control component 20 controls the indicator light 31 to turn blue according to the first detection signal. The blue light emitted by the indicator light 31 can pass through the upper shell 13. The user can judge that the desktop microphone 1 can be in the noise reduction function at this time by observing the blue light effect of the indicator light 31.

[0072] By designing a first touch area 13b, a first circuit board 21, a first detection element 22, an indicator light 31, and a controller 23, when a user's finger touches or approaches the first touch area 13b, the first detection element 22 detects the user's finger touching or approaching the first touch area 13b and generates a first detection signal. The first detection element 22 sends the first detection signal to the controller 23, and the controller 23 controls the indicator light 31 to light up in a preset direction according to the first detection signal. The indicator light 31 has multiple lighting states, and each lighting state of the indicator light 31 corresponds to a preset function of the desktop microphone 1. The light emitted by the indicator light 31 can pass through the upper shell 13, and the user can know which preset function the desktop microphone 1 is currently in by observing the current lighting state of the indicator light 31, which is convenient for the user. By designing a first touch area 13b on the side of the upper shell 13 opposite to the lower shell 11, the top touch of the desktop microphone 1 can be realized, which is convenient for users to operate. In addition, compared with designing the first touch area 13b on the side wall of the desktop microphone 1, it can effectively reduce or even avoid the situation where the user accidentally touches the first touch area 13b while holding the side wall of the desktop microphone 1.

[0073] like Figures 11-13 and Figures 17-19 As shown, the upper shell 13 includes a shell body 131 and a light guide 132. The shell body 131 has the aforementioned second receiving cavity 13a. The first circuit board 21 is connected to the shell body 131. The shell body 131 also has a through hole 131a. The light guide 132 passes through the through hole 131a to expose the shell body 131. The light guide 132 is light-transmitting so that the light emitted by the indicator light 31 can pass through the light guide 132. The shell body 131 itself can be made of a light-transmitting material. In this case, the shell body 131 needs to be coated with a light-shielding coating to block the light emitted by the indicator light 31 from passing through the second receiving cavity 13a of the shell body 131. Alternatively, the shell body 131 can be made of an opaque material. In this case, the shell body 131 is light-shielding so that the light emitted by the indicator light 31 cannot pass through the shell body 131. The light guide 132 is transparent, and the light emitted by the indicator light 31 can pass through the light guide 132. The user can use the lighting effect presented by the light guide 132 to reflect the current lighting status of the indicator light 31, and thus know which preset function the desktop microphone 1 is currently in.

[0074] The shell body 131 includes the aforementioned top seat 1311, the aforementioned blowout preventer 1312, the aforementioned base 1313, the aforementioned cover 1314, and the aforementioned connector 1315. The top seat 1311 has the aforementioned through hole 131a communicating with the receiving groove 1311a, and the cover 1314 (specifically the aforementioned top wall 1314a) has the aforementioned first touch area 13b.

[0075] The groove wall of the receiving groove 1311a is provided with a locking flange 1311b, which encloses to form a locking groove. The light guide 132 includes an insertion part 1321a, a mounting part 1321b connected to the insertion part 1321a, and a guide part 1321c connected to the mounting part 1321b. The insertion part 1321a is inserted into the through hole 131a, the mounting part 1321b engages with the locking groove, and the guide part 1321c extends above the indicator light 31. The locking flange 1311b can be, but is not limited to, formed as an integral structure with the top seat 1311 by injection molding or 3D printing. The insertion part 1321a, the mounting part 1321b, and the guide part 1321c can be, but is not limited to, integrally formed by injection molding or 3D printing. By designing the locking flange 1311b, which forms a locking groove, the mounting part 1321b engages with the locking groove to achieve relative fixation between the light guide 132 and the top seat 1311, effectively reducing the assembly difficulty between the light guide 132 and the top seat 1311. By designing the indicator light 31 below the guide part 1321c, the indicator light 31 is not directly opposite the insertion part 1321a, so the user will not see the indicator light 31 directly through the light guide 132, and there will be no shadow cast by the indicator light 31.

[0076] Other design details regarding indicator light 31 and light guide 132 may include, but are not limited to, one or more of the following:

[0077] In the first case, indicator light 31 includes a first RGB LED bead 311. The first RGB LED bead 311 is used to project multi-color light, providing multiple colors of light (such as red, orange, yellow, green, cyan, blue, and purple). The first RGB LED bead 311 includes a red light chip, a green light chip, and a blue light chip. By independently controlling the brightness of these three chips and mixing the light they project, different colors of light are obtained.

[0078] In the second case, the light guide 132 includes a main body 1321 (including the insertion part 1321a, mounting part 1321b, and guiding part 1321c described above) passing through the through hole 131a. The light-emitting surface of the main body 1321 (i.e., the surface on the light guide 132 through which the light emitted by the indicator light 31 passes) is provided with micro-protrusion structures and / or micro-recess structures. By designing micro-protrusion structures and / or micro-recess structures on the light-emitting surface of the main body 1321, the light emitted by the indicator light 31 can present a hazy atmosphere after passing through the light guide 132. Alternatively, the interior of the main body 1321 is provided with light-scattering particles. The light-scattering particles can be diffusion particles that have a diffusion effect on the light emitted by the indicator light 31. The diffusion particles can include, but are not limited to, silicone resin particles. The light-scattering particles can be integrally formed with the main body 1321 by injection molding. By designing light-scattering particles, the light emitted by the indicator light 31 enters the light guide 132 and then hits the light-scattering particles multiple times within the main body 1321, causing multiple diffusions. Finally, the light is emitted from the light-emitting surface of the main body 1321 and exits the light guide 132, thus improving the uniformity of the light emitted by the indicator light 31 within the light guide 132.

[0079] like Figure 5 and Figure 20 As shown, the cover 1314 is made of an insulating non-metallic material, and the control component 20 also includes a controller 23; the first detection element 22 includes a first capacitor (not shown in the figure), a first detection circuit (not shown in the figure), and a first conductive element 221. The first plate of the first capacitor is in contact with the cover 1314 through the first conductive element 221, and the second plate of the first capacitor is electrically connected to the controller 23 through the first detection circuit. When the user's finger touches the first touch area 13b, the capacitance value of the first capacitor changes, and the first detection circuit outputs a first detection signal generated according to the change in the capacitance value of the first capacitor; the controller 23 controls the indicator light 31 to light up according to a preset method based on the received first detection signal.

[0080] The material of the cover 1314 may be, but is not limited to, plastic, glass, or ceramic.

[0081] The controller 23 includes a signal control unit and a timing unit. The control unit is configured to receive a first detection signal and compare the value of the first detection signal with a preset threshold (which can be a comparison of frequency or a comparison of voltage value). When the comparison result shows that the value of the first detection signal is higher than the preset threshold, the control unit outputs a start timing signal to the timing unit. When the comparison result shows that the value of the first detection signal is lower than the preset threshold, the control unit outputs a stop timing signal to the timing unit. The timing unit is configured to start timing in response to the start timing signal and stop timing in response to the stop timing signal, so as to output the duration to the control unit. The control unit is also configured to compare the duration with a preset time threshold. When the duration is greater than or equal to the preset time threshold, the control unit controls the desktop microphone 1 to perform a first preset function (such as one of the above-mentioned mute function and noise reduction function). At the same time, the control unit controls the indicator light 31 to light up according to one of the preset modes corresponding to the first preset function. When the duration is less than the preset time threshold, the control unit controls the desktop microphone 1 to perform a second preset function (such as another of the above-mentioned mute function and noise reduction function). At the same time, the control unit controls the indicator light 31 to light up according to another preset mode corresponding to the second preset function. Specifically, the controller 23 is electrically connected to the second circuit board 25 (described below) of the control component 20, and the first detection circuit is integrated on the first circuit board 21. The first detection circuit includes an RC oscillator, which periodically sends a first frequency signal f1 (one of the first detection signals) to the control unit of the controller 23. The calculation formula of the first frequency signal f1 involves the capacitance value. When the user's finger touches or approaches the first touch area 13b, the change in the capacitance value Cs1 of the first capacitor is greater than 0, and the frequency decreases. When the user's finger does not touch or approach the first touch area 13b, the change in the capacitance value Cs1 of the first capacitor is equal to 0, and the frequency remains unchanged. The control unit of the controller 23 then determines whether the user's finger touches the first touch area 13b based on whether the frequency value decreases.

[0082] like Figure 5 As shown, the first conductive element 221 includes a first conductive sponge 2212. One end of the first conductive sponge 2212 is electrically connected to the first plate of the first capacitor, and the other end of the first conductive sponge 2212 abuts against the cover 1314. The first conductive sponge 2212 acts as a conductive element to pull the first plate of the first capacitor to the cover 1314. This eliminates the need to design the first plate of the first capacitor to directly contact the inner surface of the cover 1314, facilitating the assembly of various components and ensuring high sensitivity of the first capacitor.

[0083] like Figure 21As shown, the first conductive element 221 includes a first conductive spring 2211. The first end of the first conductive spring 2211 is electrically connected to the first plate of the first capacitor, and the other end of the first conductive spring 2211 contacts the cover 1314. Alternatively, the first conductive spring 2211 and the cover 1314 may not be connected; in this case, the other end of the first conductive spring 2211 directly abuts against the inner surface of the cover 1314. Or, a connection may exist between the first conductive spring 2211 and the cover 1314; in this case, the inner surface of the cover 1314 may be provided with a positioning protrusion or a positioning buckle, and the other end of the first conductive spring 2211 is connected to the positioning protrusion or positioning buckle. The first conductive spring 2211 is a metal spring. As a conductive element, the first conductive spring 2211 pulls the first plate of the first capacitor to the cover 1314. This avoids designing the first plate of the first capacitor to directly contact the inner surface of the cover 1314, facilitating assembly between components and ensuring high sensitivity of the first capacitor.

[0084] like Figure 5 As shown, the first preset function is one of noise reduction and mute functions, and the second preset function is the other of noise reduction and mute functions. The desktop microphone 1 integrates a noise reduction function, employing a DSP (Digital Signal Processor) chip and algorithm to identify and filter noise. By designing a noise reduction function for the desktop microphone 1, the noise reduction function can process the audio signal collected by the microphone 41 of the pickup component 40 to filter out noise and improve the quality of the audio signal. By designing a mute function for the desktop microphone 1, the mute function can be implemented, allowing users to activate the mute function according to actual needs, rather than directly disconnecting the desktop microphone 1, thus improving the ease of use of the desktop microphone 1.

[0085] The first touch area 13b of the cover 1314 is provided with a noise reduction indicator 13e corresponding to the noise reduction function and a mute indicator 13f corresponding to the mute function. The noise reduction indicator 13e (or mute indicator 13f) can, but is not limited to, being formed on the first touch area 13b of the cover 1314 using laser engraving technology. The noise reduction indicator 13e and the mute indicator 13f serve as functional indicators, allowing users to know that the desktop microphone 1 has noise reduction and mute functions. Furthermore, the placement of the noise reduction indicator 13e and the mute indicator 13f on the first touch area 13b of the cover 1314 provides a location indicator, allowing users to determine the location of the first touch area 13b and perform touch operations.

[0086] like Figure 5As shown, the upper shell 13 has a second touch area 13c on the side opposite to the lower shell 11 (specifically, the cover 1314 described above). The control component 20 also includes a second detection element 24, which is disposed corresponding to the second touch area 13c and electrically connected to the first circuit board 21. The second detection element 24 is used to send a second detection signal to the controller 23 of the control component 20 when the user's finger touches or approaches the second touch area 13c. The controller 23 of the control component 20 then adjusts the lighting state of the first light-emitting unit 32 according to the second detection signal.

[0087] The orthographic projection of the second detection element 24 onto the plane of the second touch area 13c falls within the second touch area 13c.

[0088] The second detection element 24 is used to detect when a user's finger touches or approaches the second touch area 13c. For example, it can be a capacitive touch, utilizing human body electric field sensing. The user's finger can touch or approach (within a certain distance) the second touch area 13c, and is detected by changing the capacitance value of the sensor surface. Alternatively, it can be an infrared touch, using an infrared emitter and receiver to form a grid. The user's finger can touch or approach (within a certain distance) the second touch area 13c, and is detected by blocking or reflecting some infrared light. Another example is a physical switch-type touch, in which case the control component 20 can also include a second switch. The upper shell 13 has a second opening on the side opposite to the lower shell 11 for the second switch to pass through. The second opening serves as the second touch area 13c. The user's finger is detected by directly contacting the second switch and applying force to it (at this time, the user's finger does not directly touch the second opening serving as the second touch area 13c but approaches it).

[0089] When a user's finger touches or approaches the second touch area 13c, the second detector 24 generates a second detection signal and sends it to the controller 23. The controller 23 adjusts the illumination state of the first light-emitting unit 32 according to the second detection signal (which may include, but is not limited to, a constant-on state, a flashing state, and a light color state). At this time, the controller 23 controls the desktop microphone 1 to perform the lighting effect adjustment function according to the second detection signal. For example, taking the illumination state of the first light-emitting unit 32 as including a red light state, a green light state, and a blue light state, the user's finger touches or approaches the second touch area 13c multiple times, causing the controller 23 to adjust the first light-emitting unit 32 between the red light state, the green light state, and the blue light state according to the second detection signal, thereby enabling the desktop microphone 1 to perform the lighting effect adjustment function. This design allows at least a portion of the second receiving cavity 13a, which houses the microphone head 41, to emit light as the pickup cavity of the desktop microphone 1. By adjusting the illumination state of the first light-emitting unit 32, the lighting effect of the pickup cavity of the desktop microphone 1 can be changed. This allows the desktop microphone 1 to not only perform sound pickup and transmission but also allow the user or others to observe the lighting effect created by the first light-emitting unit 32, creating a cool lighting atmosphere and enhancing the user experience.

[0090] like Figure 5 As shown, the second detection element 24 includes a second capacitor (not shown), a second detection circuit (not shown), and a second conductive element 241. The first plate of the second capacitor is in contact with the cover 1314 through the second conductive element 241, and the second plate of the second capacitor is electrically connected to the controller 23 through the second detection circuit. When a user's finger touches the second touch area 13c, the capacitance value of the second capacitor changes. The second detection circuit outputs a second detection signal generated according to the change in the capacitance value of the second capacitor. The controller 23 adjusts the lighting state of the first light-emitting unit 32 based on the received second detection signal to enable the desktop microphone 1 to perform a lighting effect adjustment function. The control unit of the controller 23 is configured to adjust the lighting state of the first light-emitting unit 32 in response to the second detection signal to enable the desktop microphone 1 to perform a lighting effect adjustment function.

[0091] Specifically, the second detection circuit is integrated on the first circuit board 21. The second detection circuit includes an RC oscillator, which periodically sends a second frequency signal f2 (one of the second detection signals) to the control unit of the controller 23. The calculation formula of the second frequency signal f2 involves the capacitance value. When a user's finger touches or approaches the second touch area 13c, the change in the capacitance value Cs2 of the second capacitor is greater than 0, and the frequency decreases. When no user's finger touches or approaches the second touch area 13c, the change in the capacitance value Cs2 of the second capacitor is equal to 0, and the frequency remains unchanged. The control unit of the controller 23 then determines whether a touch operation of the user's finger on the second touch area 13c has occurred based on whether the frequency value decreases.

[0092] like Figure 5 As shown, the second conductive element 241 includes a second conductive sponge 2412. One end of the second conductive sponge 2412 is electrically connected to the first plate of the second capacitor, and the other end of the second conductive sponge 2412 abuts against the cover 1314. The second conductive sponge 2412 acts as a conductive element to pull the first plate of the second capacitor to the cover 1314. This eliminates the need to design the first plate of the second capacitor to directly contact the inner surface of the cover 1314, facilitating the assembly of the components and ensuring high sensitivity of the second capacitor.

[0093] like Figure 21 As shown, the second conductive element 241 includes a second conductive spring 2411. The first end of the second conductive spring 2411 is electrically connected to the first plate of the second capacitor, and the other end of the second conductive spring 2411 contacts the cover 1314. Alternatively, the second conductive spring 2411 and the cover 1314 may not be connected; in this case, the other end of the second conductive spring 2411 directly abuts against the inner surface of the cover 1314. Or, they may be connected; in this case, the inner surface of the cover 1314 may have another positioning protrusion or another positioning buckle, and the other end of the second conductive spring 2411 is connected to the other positioning protrusion or another positioning buckle. The second conductive spring 2411 is a metal spring. As a conductive element, the second conductive spring 2411 pulls the first plate of the second capacitor to the cover 1314. This avoids designing the first plate of the second capacitor to directly contact the inner surface of the cover 1314, facilitating assembly between components and ensuring high sensitivity of the second capacitor.

[0094] like Figure 5As shown, the second touch area 13c of the cover 1314 is provided with a lighting effect indicator 13g corresponding to the lighting effect adjustment function. The lighting effect indicator 13g can, but is not limited to, being formed on the second touch area 13c of the cover 1314 using laser engraving technology. By designing the lighting effect indicator 13g, it serves as a function prompt, allowing the user to know that the pickup cavity of the desktop microphone 1 has a lighting effect adjustment function. By designing the lighting effect indicator 13g on the second touch area 13c of the cover 1314, it also serves as a location prompt, allowing the user to know the location of the second touch area 13c and perform touch operations.

[0095] like Figure 5 As shown, the second detection element 24 is used to send a second detection signal to the controller 23 of the control component 20 when the user's finger touches or approaches the second touch area 13c. The controller 23 of the control component 20 also adjusts the lighting state of the second light-emitting unit 33 according to the second detection signal (which may include, but is not limited to, a constant light state, a flashing state, and a light color state). At this time, the controller 23 controls the desktop microphone 1 to perform the lighting effect adjustment function according to the second detection signal. For example, taking the lighting state of the second light-emitting unit 33 as including a red light state, a green light state, and a blue light state as an example, when the user's finger touches or approaches the second touch area 13c multiple times, the controller 23 also adjusts the second light-emitting unit 33 to switch between the red light state, the green light state, and the blue light state according to the second detection signal, so that the desktop microphone 1 performs the lighting effect adjustment function.

[0096] When a user touches the second touch area 13c, the capacitance value of the second capacitor changes, and the second detection circuit outputs a second detection signal generated according to the change in the capacitance value of the second capacitor. The controller 23 also adjusts the lighting state of the second light-emitting unit 33 based on the received second detection signal to enable the desktop microphone 1 to perform a lighting effect adjustment function. The control unit of the controller 23 is further configured to adjust the lighting state of the second light-emitting unit 33 in response to the second detection signal to enable the desktop microphone 1 to perform a lighting effect adjustment function.
