DETAILED DESCRIPTION

[0010] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0011] The desktop microphone is a kind of microphone mainly used for placing on the desktop. It is different from handheld microphone, lapel microphone, head-mounted microphone, etc., and usually does not need to be held or worn, but is stably placed on the desktop through the base or support or cantilever support to collect audio signals. And the desktop microphone is mainly suitable for office, recording studio, live room and other application scenarios, and has wide application scenarios and is favored by users.

[0012] The desktop microphone usually has multiple preset functions such as mute function and noise reduction function, but the desktop microphone in the prior art usually has two independent buttons, one of which is used to turn on and off the mute function, and the other is used to turn on and off the noise reduction function. The two independent buttons make the structure of the desktop microphone complex, resulting in an increase in the cost of the desktop microphone.

[0013] Please refer to Figures 1-6 To solve the above problems, the present application provides a desktop microphone 1, which can realize the switching of the multifunction mode of the desktop microphone 1 by the operation of the user's finger on or near the first touch area 13b, and has a simple structure and is conducive to reducing the manufacturing cost of the desktop microphone 1.

[0014] The desktop microphone 1 comprises a shell assembly 10 and a control assembly 20. The shell assembly 10 comprises a lower shell 11 having a first accommodating cavity 11a, a mounting frame 12 at least partially located in the first accommodating cavity 11a, and an upper shell 13 having a second accommodating cavity 13a; the upper shell 13 is connected with the lower shell 11 via the mounting frame 12, and the side of the upper shell 13 away from the lower shell 11 has a first touch area 13b. The control assembly 20 comprises a first detection member 22 and a controller 23; the first detection member 22 is arranged corresponding to the first touch area 13b; and the controller 23 is electrically connected with the first detection member 22. The first detection member 22 is used to detect whether the user's finger touches or approaches the first touch area 13b; and the controller 23 is used to judge whether the feature of the touch operation of the user's finger meets a preset condition when the first detection member 22 detects that the user's finger touches or approaches the first touch area 13b; if yes, the controller 23 controls the desktop microphone 1 to execute a first preset function, otherwise, the controller 23 controls the desktop microphone 1 to execute a second preset function different from the first preset function.

[0015] The specific structure of the desktop microphone 1 will be described below. Figures 1-15

[0016] As shown in Figures 1-6 The desktop microphone 1 comprises a shell assembly 10 and a control assembly 20.

[0017] The shell assembly 10 is a shell part of the desktop microphone 1, and comprises a lower shell 11, a mounting frame 12 and an upper shell 13.

[0018] The lower shell 11 is one of the shell assemblies 10, and has a first accommodating cavity 11a, which is a 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 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.

[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 and connect 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] The upper shell 13 has a first touch area 13b on the side opposite to the lower shell 11, that is, the top of the upper shell 13 has a first touch area 13b.

[0023] like Figures 1-6 As shown, the control component 20 serves as the control module for the desktop microphone 1. The control component 20 includes a first detection element 22 and a controller 23.

[0024] The first detection element 22 is set corresponding to the first touch area 13b, that is, the orthographic projection of the first detection element 22 on the plane where the first touch area 13b is located falls within the first touch area 13b.

[0025] The first detecting member 22 is configured to detect the user's finger touching or approaching the first touch area 13b. For example, the first touch area 13b can be a capacitive touch area, and the user's finger can be detected by touching or approaching (within a certain distance) the first touch area 13b and changing the capacitance of the sensor surface. For another example, the first touch area 13b can be an infrared touch area, and the user's finger can be detected by touching or approaching (within a certain distance) the first touch area 13b and blocking or reflecting part of the infrared light. For yet another example, the first touch area 13b can be a physical switch touch area, and the control assembly 20 can further include a first switch. The side of the upper shell 13 facing away from the lower shell 11 is provided with a first opening for the first switch to pass through, and the first opening serves as the first touch area 13b. The user's finger can be detected by directly contacting the first switch and applying a force to the first switch (in this case, the user's finger does not directly touch the first opening as the first touch area 13b, but approaches the first opening as the first touch area 13b).

[0026] The controller 23 serves as the control center of the control assembly 20, and the controller 23 is electrically connected to the first detecting member 22.

[0027] The controller 23 is configured to determine whether the characteristics of the user's finger touch operation meet the preset conditions when the first detecting member 22 detects the user's finger touching or approaching the first touch area 13b. It can be understood that the specific forms of the characteristics of the user's finger touch operation are different for different touch methods. For example, for capacitive touch, the characteristics of the user's finger touch operation can include, but are not limited to, duration, trigger times, operation force, or touch trajectory. For another example, for physical switch touch, when the first switch is in the form of a physical button, the characteristics of the user's finger touch operation can include, but are not limited to, duration, trigger times, or operation force. When the first switch is in the form of a physical knob, the characteristics of the user's finger touch operation can include, but are not limited to, duration, trigger times, or rotation angle. It can be understood that when the characteristics of the touch operation are duration, the corresponding preset condition is a preset time threshold. When the characteristics of the touch operation are trigger times, the corresponding preset condition is a preset number. When the characteristics of the touch operation are operation force, the corresponding preset condition is a preset pressure threshold. When the characteristics of the touch operation are touch trajectory, the corresponding preset condition is a preset trajectory. When the characteristics of the touch operation are rotation angle, the corresponding preset condition is a preset angle threshold.

[0028] When controller 23 determines that the characteristics of the user's finger touch operation meet preset conditions, controller 23 controls desktop microphone 1 to execute a first preset function. When controller 23 determines that the characteristics of the user's finger touch operation do not meet preset conditions, controller 23 controls desktop microphone 1 to execute a second preset function different from the first preset function. The first preset function may include, but is not limited to, one of the following: mute function, noise reduction function, and stereo function; the second preset function may include, but is not limited to, another of the following: mute function, noise reduction function, and stereo function.

[0029] Based on the desktop microphone 1 in this application embodiment, by designing a first touch area 13b, a first detection element 22, and a controller 23, the controller 23 is used to determine whether the characteristics of the user's finger touch operation meet preset conditions when the first detection element 22 detects that the user's finger touches or approaches the first touch area 13b. When the controller 23 determines that the characteristics of the user's finger touch operation meet the preset conditions, the controller 23 controls the desktop microphone 1 to perform a first preset function. When the controller 23 determines that the characteristics of the user's finger touch operation do not meet the preset conditions, the controller 23 controls the desktop microphone 1 to perform a second preset function different from the first preset function. In this way, the user only needs to operate on or near the first touch area 13b to realize the switching of the multi-functional mode of the desktop microphone 1. The structure is simple and helps to reduce the manufacturing cost of the desktop microphone 1. 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.

[0030] It is worth mentioning that in related technologies, using two independent buttons would encroach on the space of other interfaces (such as headphone jacks and gain knobs), forcing the desktop microphone 1 to increase in size, which is not conducive to the miniaturization design of the desktop microphone 1. However, the desktop microphone 1 in this application reduces the number of buttons by reusing them, thereby reducing the overall size of the microphone and achieving a miniaturized design.

[0031] For example, controller 23 determines whether the duration of the user's finger touch operation reaches a preset time threshold. If controller 23 determines that the duration of the user's finger touch operation reaches (i.e., is greater than or equal to) the preset time threshold, controller 23 controls desktop microphone 1 to execute the first preset function. If controller 23 determines that the duration of the user's finger touch operation does not reach (i.e., is less than) the preset time threshold, controller 23 controls desktop microphone 1 to execute the second preset function. The characteristic of the touch operation is its duration, which is the time it takes for the user's finger to complete a single touch. When the duration reaches the preset time threshold (i.e., a long press trigger is achieved), controller 23 controls desktop microphone 1 to execute the first preset function. The specific value of the preset time threshold is not limited here; designers can design it reasonably according to actual needs. For example, the specific value of the preset time threshold can be, but is not limited to, 3 seconds, 4 seconds, or 5 seconds.

[0032] For example, controller 23 determines whether the touch force of the user's finger reaches a preset pressure threshold. If controller 23 determines that the touch force of the user's finger reaches (i.e., is greater than or equal to) the preset pressure threshold, controller 23 controls desktop microphone 1 to perform the first preset function. If controller 23 determines that the touch force of the user's finger does not reach (i.e., is less than) the preset pressure threshold, controller 23 controls desktop microphone 1 to perform the second preset function. In this case, the characteristic of the touch operation is the operating force, and when the operating force reaches the preset pressure threshold, controller 23 controls desktop microphone 1 to perform the first preset function. The specific value of the preset pressure threshold is not limited here; designers can design it reasonably according to actual needs. For example, the specific value of the preset pressure threshold can be, but is not limited to, 0.1 Newtons, 0.13 Newtons, or 0.15 Newtons.

[0033] For example, controller 23 determines whether the number of touch operations performed by the user's finger has reached a preset number. If controller 23 determines that the number of touch operations performed by the user's finger has reached (i.e., greater than or equal to) the preset number, controller 23 controls desktop microphone 1 to execute the first preset function mentioned above. If controller 23 determines that the number of touch operations performed by the user's finger has not reached (i.e., less than) the preset number, controller 23 controls desktop microphone 1 to execute the second preset function mentioned above. Here, the characteristic of the touch operation is the number of operations. Each operation is triggered by a short press, and when the number of operations reaches the preset number (i.e., multiple short presses are triggered), controller 23 controls desktop microphone 1 to execute the first preset function mentioned above. The specific value of the preset number of operations is not limited here; designers can design it reasonably according to actual needs. For example, the specific value of the preset time threshold can be, but is not limited to, two, three, four, or five times.

[0034] For example, controller 23 is used to determine whether the touch trajectory of the user's finger touch operation matches a preset trajectory. If controller 23 determines that the touch trajectory of the user's finger touch operation matches the preset trajectory, controller 23 controls desktop microphone 1 to execute the first preset function mentioned above. If controller 23 determines that the touch trajectory of the user's finger touch operation does not match the preset trajectory, controller 23 controls desktop microphone 1 to execute the second preset function mentioned above. At this time, the characteristic of the touch operation is the touch trajectory, and when the touch trajectory matches (i.e., is consistent) with the preset trajectory, controller 23 controls desktop microphone 1 to execute the first preset function mentioned above. The specific form of the preset trajectory is not limited here, and designers can design it reasonably according to actual needs; for example, the preset trajectory can be, but is not limited to, a unidirectional leftward sliding trajectory, a unidirectional rightward sliding trajectory, a unidirectional upward sliding trajectory, a unidirectional downward sliding trajectory, or a Z-shaped sliding trajectory.

[0035] like Figures 3-7 As shown, the control component 20 also includes a first circuit board 21, and the first detection element 22 is electrically connected to the first circuit board 21. The upper shell 13 includes a shell body 131, which includes a top seat 1311 and a cover 1314. The top seat 1311 has a receiving groove 1311a on the side opposite to the lower shell 11. At least a portion of the first circuit board 21 is located in the receiving groove 1311a and connected to the top seat 1311. The cover 1314 is connected to the top seat 1311 to cover the opening of the receiving groove 1311a. The cover 1314 has the aforementioned first touch area 13b.

[0036] 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. The specific connection method between the cover 1314 and the top seat 1311 is not limited here, and designers can make reasonable designs according to actual needs; for example, the cover 1314 can be detachably and fixedly connected to the top seat 1311 by at least one of the following methods: screw connection, snap connection, or plug connection; or, for example, the cover 1314 can be non-detachably and fixedly connected to the top seat 1311 by riveting or gluing. Specifically, in the embodiments of this application, such as Figure 5 As shown, the groove wall of the receiving groove 1311a of the top seat 1311 is provided with a snap-fit ​​flange 1311c; the cover 1314 includes a top wall 1314a and a side wall 1314b circumferentially connected to the top wall 1314a. The top wall 1314a has the aforementioned first touch area 13b, and the side wall 1314b is provided with a latch 1314c, which is used to engage with the snap-fit ​​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 is not limited to this method. By designing the snap-fit ​​flange 1311c and the latch 1314c, and by engaging with the snap-fit ​​flange 1311c and the latch 1314c, the relative position between the cover 1314 and the top seat 1311 is fixed. The structure is simple and easy to implement.

[0037] The cover 1314 is made of an insulating non-metallic material. 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, causing the first detection circuit to output a first detection signal generated as the capacitance value of the first capacitor changes. The controller 23 obtains the duration of the user's finger touch operation on the first touch area 13b based on the relationship between the value of the received first detection signal and a preset threshold. When the duration is greater than or equal to the preset time threshold, the controller controls the desktop microphone 1 to perform the first preset function, and when the duration is less than the preset time threshold, the controller controls the desktop microphone 1 to perform the second preset function.

[0038] The material of the cover 1314 may be, but is not limited to, plastic, glass, or ceramic.

[0039] 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 its value with a preset threshold (which can be a comparison of frequency or voltage value). When the comparison result shows the first detection signal value is higher than the preset threshold, the control unit outputs a start timing signal to the timing unit; when the comparison result shows the first detection signal value 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, outputting a duration. 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 the first preset function; when the duration is less than the preset time threshold, the control unit controls the desktop microphone 1 to perform 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.

[0040] like Figure 5As 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.

[0041] like Figure 8 As 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.

[0042] like Figure 1 , Figure 2 and 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 of the desktop microphone 1 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 so that the user can turn on the mute function according to actual needs, instead of directly disconnecting the desktop microphone 1, thus improving the ease of use of the desktop microphone 1.

[0043] The first touch area 13b 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, be 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.

[0044] like Figure 1 , Figure 2 and Figure 6 As 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 (such as...) Figure 15 As shown, the wireless module 60 is electrically connected to the second circuit board 25, and the wireless module 60 is used for wireless communication with the wireless communication device 50. By designing the wireless module 60, the wireless module 60 is wirelessly connected to the terminal through the wireless communication device 50 to transmit audio signals wirelessly, thus obtaining the wireless desktop microphone 1 and reducing the use of cables.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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 terminal 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.

[0049] The microphone 41 of the pickup component 40 of the desktop microphone 1 (described below) collects audio signals and sends the audio signals 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.

[0050] 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.

[0051] 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.

[0052] The desktop microphone 1 also includes a battery (not shown) electrically connected to the second circuit board 25. The mounting bracket 12 has a cylindrical structure, and the battery is located inside the cavity 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.

[0053] like Figures 9-14 As shown, the desktop microphone 1 also includes a light-emitting component 30, which includes an indicator light 31. The indicator light 31 is electrically connected to the first circuit board 21 and is configured such that the emitted light can pass through the upper shell 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 illumination 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 illumination state of the indicator light 31.

[0054] The first detection element 22 is used to send a first detection signal to the controller 23 when the user's finger touches or approaches the first touch area 13b. The controller 23 also 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.

[0055] 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. The controller 23 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. The controller 23 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. The controller 23 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 is in mute mode by 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. The controller 23 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 is in noise reduction mode by the blue light effect of the indicator light 31.

[0056] Specifically, the upper shell 13 also includes a light guide 132. The top seat 1311 is provided with a through hole 131a communicating with the receiving groove 1311a. 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 top seat 1311 itself can be made of a light-transmitting material. In this case, the light-transmitting top seat 1311 needs to be coated with a light-shielding coating so that the light emitted by the indicator light 31 is blocked by the light-shielding coating and cannot pass out of the receiving groove 1311a of the top seat 1311. Alternatively, the top seat 1311 itself can be made of an opaque material. In this case, the top seat 1311 is light-shielding so that the light emitted by the indicator light 31 cannot pass through the top seat 1311. 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.

[0057] 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.

[0058] Other design details regarding indicator light 31 and light guide 132 may include, but are not limited to, one or more of the following:

[0059] 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.

[0060] 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.

[0061] like Figure 3 , Figure 4 , Figure 6 , Figure 10 and Figure 11 As shown, the light-emitting component 30 also includes a first light-emitting unit 32, which is electrically connected to the first circuit board 21. 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 desktop microphone 1 also includes a pickup component 40, which includes a microphone 41 and a light-transmitting element 42. The microphone 41 is mounted on the mounting bracket 12 and is at least partially located within the second receiving cavity 13a of the upper shell 13. At least a portion of the light-transmitting element 42 is located within the second receiving cavity 13a of the upper shell 13, and the light-transmitting element 42 is arranged around the microphone 41. A portion of the upper shell 13 is hollowed out to form a hollow area 13d communicating with the second receiving cavity 13a. The first light-emitting unit 32 is configured such that the emitted light can pass through the light-transmitting element 42 and the hollow area 13d.

[0062] The shell body 131 also includes a base 1313 and a connector 1315. The base 1313 is closer to the lower shell 11 than the top seat 1311. The base 1313 is connected to the lower shell 11. The connector 1315 is a long columnar structure. The connector 1315 is located between the top seat 1311 and the base 1313. One end of the connector 1315 is fixedly connected to the top seat 1311, and the other end of the connector 1315 is fixedly connected to the base 1313, so as to connect the top seat 1311 and the base 1313 into a whole (the connector 1315 can be, but is not limited to, forming an integral structure with the top seat 1311 and the base 1313 by injection molding or 3D printing). The base 1313, the connector 1315 and the top seat 1311 together form a hollow area 13d. The bottom wall of the receiving groove 1311a of the top seat 1311 is provided with a clearance hole 1311d that communicates with the second receiving cavity 13a. The first light-emitting unit 32 passes through the clearance hole 1311d and is at least partially located in the second receiving cavity 13a.

[0063] The microphone 41 is used to collect audio signals. 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 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 fixedly connected to the mounting bracket 12 by adhesive bonding or riveting.

[0064] 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 with the microphone 41 surrounding it. The specific connection relationship between the light-transmitting element 42 and the upper shell 13 is not limited here, and the designer can make reasonable designs 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 is embedded. The shell body 131 also includes a pop filter 1312, which is located around the light-transmitting element 42. The top seat 1311, the pop filter 1312, and the base 1313 together form the second receiving cavity 13a. The pop filter 1312 can be detachably fixedly connected to the top seat 1311 (or the base 1313) by at least one of the following methods: screwing, snap-fitting, or plugging.

[0065] The light emitted by the first light-emitting unit 32 can pass through the light-transmitting part 42 and the hollow area 13d. At least part of the second receiving cavity 13a used to accommodate the microphone head 41 can emit light as the sound pickup cavity of the desktop microphone 1. This allows the desktop microphone 1 to not only have the function of sound pickup and transmission, but also to be observed by the user or others in the light effect created by the first light-emitting unit 32, creating a cool lighting atmosphere, enhancing the atmosphere, and improving the user experience.

[0066] like Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, the upper shell 13 has a second touch area 13c on the side opposite to the lower shell 11 (specifically, the cover 1314 mentioned 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 control component 20 when the user's finger touches or approaches the second touch area 13c. The control component 20 then adjusts the lighting state of the first light-emitting unit 32 according to the second detection signal.

[0067] 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.

[0068] 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).

[0069] 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.

[0070] The second detection element 24 includes a second capacitor (not shown in the figure), a second detection circuit (not shown in the figure), 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 the user's finger touches the second touch area 13c, the capacitance value of the second capacitor changes, causing the second detection circuit to output 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 according to the received second detection signal to enable the desktop microphone 1 to perform the 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 the lighting effect adjustment function.

[0071] 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.

[0072] 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.

[0073] like Figure 8 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.

[0074] 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.

[0075] like Figure 3 , Figure 4 , Figure 5 , Figure 10 , Figure 11 and Figure 15 As shown, the control component 20 also includes a third circuit board 26, which is located at one end of the upper shell 13 near the lower shell 11 and is electrically connected to the second circuit board 25; the light-emitting component 30 also includes a second light-emitting unit 33, which is electrically connected to the third circuit board 26. At least a portion of the second light-emitting unit 33 is located in the second receiving cavity 13a of the lower shell 11, and the second light-emitting unit 33 is configured such that the light emitted can pass through the light-transmitting element 42 and the hollow area 13d.

[0076] Here, the specific connection relationship between the third circuit board 26 and the upper shell 13 (specifically the base 1313 described above) is not limited, and the designer can make reasonable designs according to actual needs; for example, the third circuit board 26 can be detachably fixedly connected to the upper shell 13 by at least one of the following methods: screwing, snap-fitting, or plugging; or, for example, the third circuit board 26 can also be non-detachably fixedly connected to the upper shell 13 by means of gluing or riveting.

[0077] The second detection element 24 is used to send a second detection signal to the control component 20 when the user's finger touches or approaches the second touch area 13c. 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, if the user's finger touches or approaches the second touch area 13c multiple times, the controller 23 will also adjust 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, thereby enabling the desktop microphone 1 to perform the lighting effect adjustment function.

[0078] 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.

[0079] It is understood that the first light-emitting unit 32 is located on the side of the top seat 1311 of the upper shell 13, and the second light-emitting unit 33 is located on the side of the base 1313 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, achieving light emission from both sides. 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. Thus, 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. It should be noted that when the pickup cavity of the desktop microphone 1 emits light, 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.

[0080] Specifically, the first light-emitting unit 32 includes a plurality of second RGB LED beads 321 electrically connected to the first circuit board 21, and the plurality of second RGB LED beads 321 are distributed in a first area of ​​the first circuit board 21. The second light-emitting unit 33 includes a plurality of third RGB LED beads 331 electrically connected to the third circuit board 26, and the plurality of third RGB LED beads 331 are distributed in a second area of ​​the third circuit board 26. The orthographic projection of the first area onto the plane of the second area does not coincide with the second area. For example, the plurality of second RGB LED beads 321 are concentrated in the central area of ​​the first circuit board 21 (i.e., the aforementioned first area), while the plurality of third RGB LED beads 331 are distributed circumferentially along the inner edge area of ​​the third circuit board 26 (i.e., the aforementioned second area). 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, different colors of light are obtained. 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 their projected light, different colors of light are obtained. It should be noted that the color of the light emitted by the second RGB LED bead 321 can be the same as or different from the color of the light emitted by the third RGB LED bead 331.
