[0009] 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.

[0010] Please refer to Figures 1-4 As shown, this application proposes a desktop microphone 1 that enables wireless transmission of audio signals without the need for additional wiring, making it more flexible and convenient, and effectively meeting the needs of scenarios such as live streaming, e-sports voice communication, and online conferencing.

[0011] The desktop microphone 1 includes a housing assembly 10, a control assembly 20, a wireless communication device 50, and a wireless module 60. The housing assembly 10 includes a lower shell 11 having a first receiving cavity 11a, a mounting bracket 12 at least partially located within the first receiving cavity 11a, and an upper shell 13 having a second receiving cavity 13a. The lower shell 11 is connected to the upper shell 13 via the mounting bracket 12, and the lower shell 11 has an unshielded area. The control assembly 20 includes a second circuit board 25 and a gain adjustment switch 27. The second circuit board 25 is mounted on the mounting bracket 12 and at least partially located within the first receiving cavity 11a of the lower shell 11. The gain adjustment switch 27 is disposed on the lower shell 11 and electrically connected to the second circuit board 25. The wireless communication device 50 is used to connect to an external terminal. The wireless module 60 is disposed corresponding to the unshielded area and communicates wirelessly with the wireless communication device 50.

[0012] The following combination Figures 1-19 The specific structure of the desktop microphone 1 will be described in detail.

[0013] like Figures 1-4 As shown, the desktop microphone 1 includes a housing assembly 10, a control assembly 20, a wireless communication device 50, and a wireless module 60.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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 of the desktop microphone 1 (described below). 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.

[0018] 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.

[0019] like Figures 1-4 As shown, the control component 20 serves as the control module for the desktop microphone 1. The control component 20 includes a second circuit board 25 and a gain adjustment switch 27.

[0020] The second circuit board 25 can be a rigid circuit board, a flexible circuit board, or a combination of both. The second circuit board 25 is mounted on the mounting bracket 12 and is at least partially located within the first receiving cavity 11a of the lower housing 11. The specific connection method between the second circuit board 25 and the mounting bracket 12 is not limited; designers can design it reasonably according to actual needs. For example, the second circuit board 25 can 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 can be non-detachably fixedly connected to the mounting bracket 12 by, but not limited to, adhesive bonding or riveting. It should be noted that when the second circuit board 25 is a flexible circuit board, the control assembly 20 may also include another reinforcing plate, which is disposed on one side of the flexible circuit board to provide support.

[0021] The gain adjustment switch 27 is used to control the sensitivity of the microphone 41 of the pickup component 40 of the desktop microphone 1 in picking up audio signals. It also adjusts the volume of the audio signal to obtain a clearer audio signal. The gain adjustment switch 27 is located on the lower housing 11 and electrically connected to the second circuit board 25. Users can effectively adjust the sensitivity and volume of the acquired audio signal by operating the gain adjustment switch 27.

[0022] like Figures 1-4 As shown, the wireless communication device 50 is used to connect to an external terminal, which may include, but is not limited to, tablet computers, laptops, desktop computers, ultra-mobile personal computers (UMPCs), netbooks, mobile phones, etc.

[0023] like Figures 1-4 As shown, the wireless module 60 serves as the wireless communication terminal of the desktop microphone 1. The wireless module 60 wirelessly connects to an external terminal via the wireless communication device 50 to transmit audio signals wirelessly. The microphone 41 of the pickup component 40 of the desktop microphone 1 collects audio signals and sends them to the controller 23 of the control component 20 (described below). The controller 23 of the control component 20 sends the audio signals to the wireless module 60, which then wirelessly transmits the audio signals to the wireless communication device 50. The wireless communication device 50 then sends the audio signals to the external terminal, enabling the external terminal to play audio in real time based on the audio signals. Alternatively, the audio signal (which may be a processed audio signal obtained from the external terminal) 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.

[0024] 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.

[0025] like Figures 1-4 As shown, it can be understood that the lower shell 11 serves as the shell of the desktop microphone 1. The lower shell 11 can be made of metal (such as aluminum alloy, stainless steel or brass, etc.), or it can be made of insulating non-metallic material (such as plastic, rubber, ceramic or glass, etc.). The lower shell 11 can also have a part of its structure made of metal and the remaining part of its structure made of insulating non-metallic material.

[0026] To ensure the stability of audio signal transmission during wireless communication between the wireless module 60 and the wireless communicator 50, the lower shell 11 is designed with an unshielded area for audio signals to pass through, and the wireless module 60 is positioned corresponding to this unshielded area. For example, when the lower shell 11 is entirely made of metal, the unshielded area is an opening 11b formed on the lower shell 11, and the wireless module 60 is positioned corresponding to the opening 11b, allowing audio signals to pass through. Alternatively, when the lower shell 11 is entirely made of insulating non-metallic material, the unshielded area is the entire lower shell 11, and the wireless module 60 is positioned corresponding to the lower shell 11, allowing audio signals to pass through. Yet another example: when a portion of the lower shell 11 is made of metal and the remaining portion is made of insulating non-metallic material, the unshielded area is the portion of the lower shell 11 made of insulating non-metallic material, and the wireless module 60 is positioned corresponding to this portion, allowing audio signals to pass through.

[0027] Based on the desktop microphone 1 in this embodiment, by designing the wireless module 60, the wireless communication device 50, and the unshielded area, audio signals can be smoothly transmitted wirelessly from the end of the wireless module 60 through the unshielded area to the wireless communication device 50. This also allows audio signals (which may be processed audio signals obtained from terminal processing) to be smoothly transmitted wirelessly from the end of the wireless communication device 50 through the unshielded area to the wireless module 60, reducing or even eliminating interference, ensuring audio signal quality, improving the stability of audio signal transmission, and preventing signal interruption. This achieves wireless transmission of audio signals without the need for additional wiring, making it more flexible and convenient, and effectively meeting the needs of scenarios such as live streaming, e-sports voice communication, and web conferencing. By designing a gain adjustment switch 27, the gain adjustment switch 27 is used to control the sensitivity of the microphone 41 of the pickup component 40 of the desktop microphone 1 in picking up audio signals. The gain adjustment switch 27 is also used to adjust the volume of the audio signal to obtain a clearer audio signal. Users can effectively adjust the sensitivity and volume of the acquired audio signal by operating the gain adjustment switch 27.

[0028] like Figures 1-4As shown, at least a portion of the lower shell 11 is made of an insulating non-metallic material to form the aforementioned unshielded area. The material of at least a portion of the lower shell 11 can be, but is not limited to, insulating non-metallic materials such as plastic, ceramic, or wood. Thus, the area of ​​the lower shell 11 made of an insulating non-metallic material serves as the 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 through 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 the audio signal transmission, and preventing signal interruption. In this embodiment, the lower shell 11 is entirely made of an insulating non-metallic material, which reduces the processing difficulty and cost of the lower shell 11.

[0029] like Figures 5-7 As shown, the desktop microphone 1 also includes a pickup assembly 40, which includes a microphone 41. The microphone 41 is mounted on the top of the mounting bracket 12, and at least a portion of the microphone 41 is located within the second receiving cavity 13a of the upper shell 13. The microphone 41 is used to collect audio signals, 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. The specific installation method between the microphone 41 and the top of the mounting bracket 12 is not limited here; designers can design it reasonably according to actual needs. For example, the microphone 41 can be detachably and fixedly connected to the top of the mounting bracket 12 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the microphone 41 can be non-detachably and fixedly connected to the top of the mounting bracket 12 by riveting or gluing, but not limited to this method.

[0030] The desktop microphone 1 also includes a battery 80 electrically connected to the second circuit board 25. The mounting bracket 12 includes a cylindrical body 121, the cavity of which serves as at least a portion of the battery 80 mounting slot 121a for mounting the battery 80, and at least a portion of the cylindrical body 121 extends into the second receiving cavity 13a of the upper housing 13. The microphone 41 is mounted on the top of the cylindrical body 121. By designing the cylindrical body 121 so that its cavity serves as at least a portion of the battery mounting slot 121a, the overall size of the desktop microphone 1 can be reduced by fully utilizing the space within the cylindrical body 121 to house the battery 80. Specifically, the mounting bracket 12 also includes a support 124 through which the microphone 41 is connected to the top of the cylindrical body 121. The battery 80 provides the desktop microphone 1 with the power required for operation, eliminating the limitations of cables and providing energy assurance for high-quality audio signals and reliable wireless transmission.

[0031] The desktop microphone 1 also includes an elastic insulator 90, which is disposed between the second circuit board 25 and the battery 80, and in contact with both the second circuit board 25 and the battery 80. The elastic insulator 90 can be, but is not limited to, an elastic rubber pad, an elastic rubber block, an elastic silicone pad, an elastic silicone block, or an EVA (Ethylene-Vinyl Acetate) cotton block. By designing the elastic insulator 90, it firstly provides electrical insulation between the battery 80 and the second circuit board 25; secondly, it provides support for the battery 80, enhancing its stability within the battery mounting slot 121a; and thirdly, it provides cushioning and shock absorption for the battery 80, thus reducing the possibility of the battery 80 becoming loose.

[0032] like Figures 5-8 As shown, the mounting frame 12 also includes a support plate 122 and a side plate 123. The support plate 122 is an annular structure fitted around the outer periphery of the cylinder 121. 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. The cylinder 121, the support plate 122, and the side plate 123 can be, but are not limited to, formed into an integral structure by injection molding or 3D printing.

[0033] 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 around the outer periphery of the cylinder 121. The third circuit board 26 is electrically connected to the second circuit board 25 mentioned above. The third circuit board 26 is annular, and the annular third circuit board 26 is sleeved around the outer periphery of the cylinder 121. When there is a connection between the third circuit board 26 and the support plate 122, the third circuit board 26 can be detachably and fixedly connected to the support plate 122 by at least one of the following methods, including but not limited to screwing, snap-fitting, or plugging. Alternatively, the third circuit board 26 can be non-detachably and fixedly connected to the support plate 122 by riveting or gluing, but not limited to this method.

[0034] The desktop microphone 1 also includes a light-emitting component 30, which includes a second light-emitting unit 33. The second light-emitting unit 33 is electrically connected to the third circuit board 26, and the second light-emitting unit 33 is configured to emit light that can pass through the upper shell 13. At least a portion of the second light-emitting unit 33 is located within the second receiving cavity 13a of 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, which is 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.

[0035] 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.

[0036] 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.

[0037] 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 10As 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.

[0038] Of course, in some other embodiments, the third circuit board 26 can also have a non-ring-shaped structure (e.g., circular). In this case, the mounting bracket 12 has a hollow structure (e.g., a hollow frame structure formed by multiple ribs). The third circuit board 26 is located within the hollow area of ​​the mounting bracket 12, and multiple third RGB LED beads 331 are concentrated in the middle of the third circuit board 26. This allows the multiple third RGB LED beads 331 to converge inwards as much as possible, effectively reducing the generation of black spots. In yet another embodiment, the third circuit board 26 can also have a non-ring-shaped 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 within the cavity of the mounting bracket 12. Multiple third RGB LED beads 331 are concentrated in the middle of the third circuit board 26, and the light-transmitting mounting bracket 12 does not obstruct the light emitted by the multiple third RGB LED beads 331. This allows the multiple third RGB LED beads 331 to converge inwards as much as possible, effectively reducing the generation of black spots.

[0039] like Figure 11 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 is sleeved on the outer periphery of the lower shell 11. The lower shell 11 is connected to the second bracket 72 via the elastic body 73.

[0040] 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).

[0041] 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.

[0042] Elastomer 73 is suitable for elastic deformation under stress, so as to buffer and dampen the shell.

[0043] Specifically, the other structural designs of the support component 70 and the specific designs of the elastomer 73 may include, but are not limited to, one or more of the following:

[0044] In the first scenario, when the second bracket 72 is rotatably connected to the first bracket 71, the support assembly 70 further includes a locking member 74, which is used to position the second bracket 72 against the first bracket 71. The locking member 74 can be, but is not limited to, a locking screw or a locking pin. By designing the locking member 74, after the angle between the second bracket 72 and the first bracket 71 is fixed, the locking member 74 locks the second bracket 72 firmly to the first bracket 71, preventing relative rotation between the second bracket 72 and the first bracket 71.

[0045] In the second scenario, the outer peripheral 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. Multiple elastic bodies 73 are present, each including an elastic hook 731. One end of the elastic hook 731 engages with two adjacent first latches 11c, and the other end engages with a corresponding second latch 72a. By designing multiple first latches 11c on the outer peripheral surface of the lower shell 11, multiple second latches 72a on the inner annular surface of the second bracket 72, and designing the elastic elements as elastic hooks 731, the connection between the lower shell 11 and the second bracket 72 can be achieved by the elastic hooks 731 engaging with two adjacent first latches 11c and with a corresponding second latch 72a. This structure is simple and easy to implement.

[0046] In the third scenario, a mounting portion 72b is provided at the connection point between the second bracket 72 and the first bracket 71. The wireless communication device 50 is detachably mounted on the mounting portion 72b, allowing the user to remove the wireless communication device 50 from the mounting portion 72b when the desktop microphone 1 is needed, and to reposition the wireless communication device 50 back on the mounting portion 72b when the desktop microphone 1 is no longer needed, thus preventing the wireless communication device 50 from being lost. The mounting portion 72b can be a hook on the second bracket 72, in which case the wireless communication device 50 has a retaining ring that engages with the hook; alternatively, the mounting portion 72b can be a magnet on the second bracket 72, in which case the wireless communication device 50 has another magnet that magnetically engages with the magnet. In this embodiment, the mounting portion 72b includes a mounting slot on the second bracket 72, into which the wireless communication device 50 is detachably inserted.

[0047] like Figures 12-14 As shown, considering that the gain adjustment switch 27 is used to control the sensitivity of the microphone 41 in picking up audio signals on the one hand, and to adjust the volume of the audio signal on the other hand, so as to obtain a clearer audio signal, the specific form of the gain adjustment switch 27 and the specific design position of the gain adjustment switch 27 on the lower shell 11 may include, but are not limited to, the following situations.

[0048] In the first scenario, 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 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, located on the side of the lower housing 11 opposite to the upper housing 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.

[0049] In the second scenario, 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, 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.

[0050] like Figure 2 , Figure 3 , Figure 15 and Figure 16As 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.

[0051] 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.

[0052] The control assembly 20 also includes a first circuit board 21, which is located within the receiving groove 1311a and connected to the top seat 1311. The first circuit board 21 is electrically connected to the aforementioned second circuit board 25. The light-emitting assembly 30 also includes a first light-emitting unit 32, which 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 emitted light can pass through the pop filter 1312. It is understood that the first light-emitting unit 32 may be located on the side where the top seat 1311 of the upper shell 13 is located, and the second light-emitting unit 33 may be located on the side where the base 1313 of the upper shell 13 is located. At least a portion of the second receiving cavity 13a used to receive the microphone 41 serves as the pickup cavity of the desktop microphone 1, enabling light emission from both sides, thereby making the brightness distribution of the pickup cavity of the desktop microphone 1 more uniform.

[0053] The first circuit board 21 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 seat 1311. The specific connection method between the first circuit board 21 and the top seat 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 seat 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 seat 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] like Figure 2 , Figure 3 , Figure 12 and Figure 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] like Figures 15-18As 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.

[0063] 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).

[0064] like Figures 15-18 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 shell 13 (specifically, the top mount 1311 described above). 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] like Figures 15-18 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.

[0069] 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.

[0070] 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.

[0071] Other design details regarding indicator light 31 and light guide 132 may include, but are not limited to, one or more of the following:

[0072] 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.

[0073] 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.

[0074] like Figure 16 and Figure 19 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.

[0075] The material of the cover 1314 may be, but is not limited to, plastic, glass, or ceramic.

[0076] The controller 23 includes a signal control unit (not shown in the figure) and a timing unit (not shown in the figure). 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 is 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 is 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, 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 a user's finger is detected touching or approaching 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 no user's finger is detected touching or approaching 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 a touch operation of the user's finger on the first touch area 13b has occurred based on whether the frequency value decreases.

[0077] like Figure 16 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.

[0078] like Figure 19As 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.

[0079] like Figure 16 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.

[0080] 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.

[0081] like Figure 16As 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.

[0082] 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.

[0083] 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).

[0084] 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.

[0085] like Figure 16 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, 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 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.

[0086] 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.

[0087] like Figure 16 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.

[0088] like Figure 19 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.

[0089] like Figure 16As 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.

[0090] like Figure 16 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.

[0091] When a user's finger touches or approaches the second touch area 13c, the capacitance value of the second capacitor changes, and the second detection circuit outputs a second detection signal generated in response to the change in the capacitance value of the second capacitor. The controller 23 also adjusts the illumination 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 illumination 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.

[0092] It should be noted that when a user touches or approaches the second touch area 13c to enable the desktop microphone 1 to perform the lighting effect adjustment function, the lighting state of the first light-emitting unit 32 and the lighting state of the second light-emitting unit 33 can be the same or different.
