Description

Technical Field

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

[0002] In modern video conferencing scenarios, ceiling microphones are widely used due to their advantages such as being able to be hidden in the ceiling, not taking up desktop space, and achieving uniform sound coverage in the conference room. Traditional ceiling microphones generally adopt an integrated structure, that is, integrating the pickup unit, signal processing circuit, power module, etc. into a single housing, and fixing it to the ceiling with a mounting bracket.

[0003] This integrated structure results in a large overall weight and thickness of the device, making it difficult to adapt to different spaces and achieve stable embedded installation in thin or specially structured ceilings. Furthermore, this structure presents a dilemma: balancing installation stability, sound quality, and ease of disassembly is challenging. Ensuring installation stability typically requires complex locking mechanisms, leading to cumbersome disassembly and requiring the entire unit to be removed for maintenance. Conversely, simplifying the installation structure for ease of disassembly can compromise stability, potentially causing structural vibration noise due to loosening, thus degrading sound quality.

[0004] This demonstrates that traditional integrated ceiling microphone architectures inherently present a trade-off between installation stability, sound quality, and ease of assembly and disassembly, making simultaneous optimization difficult. Therefore, significantly improving the ease of assembly and disassembly of ceiling microphones while ensuring installation stability and sound quality has become a pressing issue. Summary of the Invention

[0005] This application provides a ceiling microphone system that balances the installation stability, sound quality, and ease of installation and removal of ceiling microphones.

[0006] In a first aspect, a ceiling microphone system is provided, comprising: at least one pickup panel for picking up audio signals; a first host, physically separated from the pickup panel, for receiving and processing the audio signals to obtain an output signal; a transmission cable connected between the pickup panel and the first host for transmitting the audio signals to the first host; and a mounting assembly for detachably mounting the pickup panel to the ceiling; wherein the mounting assembly has a constrained state and a released state; in the constrained state, the mounting assembly restricts the displacement of the pickup panel relative to the ceiling; in the released state, the mounting assembly releases the displacement restriction of the pickup panel relative to the ceiling.

[0007] In summary, this embodiment of the application physically separates the pickup panel from the first host and connects them via a transmission cable. This allows the pickup panel to be independently deployed at the pickup location on the ceiling, while the first host can be flexibly placed in other locations (e.g., inside or near the ceiling). On one hand, this architecture keeps the pickup panel away from potential interference sources such as processing circuits and power modules in the first host, physically isolating the coupling of circuit noise to the front-end audio signal, thus helping to maintain the high signal-to-noise ratio and high fidelity of the original audio signal. On the other hand, since the first host no longer needs to be integrated with the pickup panel in the same housing, it can be deployed nearby according to actual wiring conditions, thereby shortening the transmission path of the audio signal (especially unamplified analog signals) and reducing the risk of interference and attenuation introduced during transmission. Even if the transmission cable has a certain length, balanced transmission or digital transmission can be used to further improve anti-interference capabilities, and the split design provides a structural basis for such optimizations. On the other hand, the split design allows for flexible adjustment of the number, position, and angle of the pickup panels according to the actual acoustic structure of the conference room (such as room size, reverberation time, and location of background noise sources), thereby optimizing the pickup coverage, reducing blind spots, improving far-field sensitivity, and suppressing environmental reverberation, thus improving the overall sound quality at the system level.

[0008] Building upon this foundation, the mounting components enable detachable installation between the microphone panel and the ceiling by switching between constrained and released states. In the constrained state, the mounting components limit the displacement of the microphone panel relative to the ceiling, ensuring installation stability during long-term use. In the released state, the displacement restriction is lifted, allowing the microphone panel to be quickly removed or reinstalled. This eliminates the need for complex permanent locking structures for stability, and avoids sacrificing installation rigidity for ease of installation and removal. It significantly simplifies maintenance while ensuring stable sound pickup, enabling the microphone system to simultaneously meet the aesthetic requirements of the conference room ceiling, long-term operational reliability, ease of on-site deployment and maintenance, and guarantee high-fidelity overall sound quality.

Detailed Implementation

[0013] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0014] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0015] In modern remote collaboration and communication, conference rooms have become a core setting for high-quality audio interaction. Ceiling microphones are widely used due to their advantages such as being able to be hidden in the ceiling, not occupying desktop space, and achieving uniform sound field coverage. Existing ceiling microphones generally adopt an integrated structure, that is, the pickup unit, signal processing circuit, and power module are all integrated into the same housing, and the whole unit is fixed to the ceiling by a mounting bracket.

[0016] In actual deployment and use, the integrated structure reveals several inherent contradictions: First, the unit is relatively heavy and thick, and when the ceiling uses lightweight and thin materials, the equipment often cannot be embedded flat, and gaps are easily generated on the installation surface; Second, to ensure installation stability, a complex locking structure is usually required, which makes disassembly and assembly cumbersome. During maintenance, the entire unit must be removed and all internal connections disconnected, which can easily damage the ceiling surface and is time-consuming; Conversely, if the installation structure is simplified in pursuit of ease of disassembly and assembly, the entire unit is susceptible to environmental vibrations (such as micro-vibrations of the building structure and excitation by air conditioning airflow) and will produce slight displacements. These displacements are transmitted to the pickup unit through the rigid shell, introducing low-frequency structural noise and degrading speech clarity.

[0017] For a long time, those skilled in the art have proposed various partial improvement solutions to address the above-mentioned problems, such as adding vibration damping materials, optimizing circuit layout to reduce electromagnetic interference, and improving the locking method of the mounting bracket. However, none of these measures can simultaneously achieve installation stability, high-fidelity sound quality, and ease of installation and removal—improving one indicator often comes at the cost of sacrificing one or two others. A technological bias has gradually formed in the industry: for ceiling microphones, there is an irreconcilable contradiction between stability, sound quality, and ease of installation and removal, and trade-offs can only be made according to specific application scenarios; it is impossible to improve all three simultaneously through existing technological approaches.

[0018] Prior to filing this application, the inventors conducted an in-depth analysis of the pain points in actual use during meetings and realized that the root cause of the aforementioned contradictions was not a defect in a single component, but rather the traditional integrated architecture itself: forcibly integrating the heavy processing circuitry, power module, and vibration-sensitive pickup unit into the same housing, thus coupling the installation load, vibration transmission path, and disassembly / removal operations together. Any change to the installation structure would simultaneously affect stability and sound quality. In other words, to simultaneously achieve lightweight and stable installation, non-destructive and rapid disassembly / removal, and system continuity during maintenance, it is necessary to break away from the inherent design approach of "the pickup unit and the main unit being physically inseparable."

[0019] Based on this, this application provides a ceiling microphone system 10. For the physically separated pickup panel 100 and first host 200, the installation and maintenance of the microphone system 10 are simplified and efficient, while maintaining the overall aesthetics of the conference room ceiling 20, long-term operational reliability, and ensuring high-fidelity overall sound quality. Those skilled in the art should understand that the term "ceiling" in this application embodiment should be understood as the suspended ceiling of the conference room or any mounting base for ceiling-mounted equipment. It can be a lightweight, thin material, gypsum board, mineral wool board, etc., or a keel structure suspended under a concrete ceiling slab. For ease of description, "ceiling" will be used as a general term for the mounting base below.

[0020] refer to Figure 1 and Figure 2 This application provides a ceiling microphone system 10, including a pickup panel 100, a first host 200, a transmission cable 300, and a mounting assembly 400. At least one pickup panel 100 is provided, and each pickup panel 100 is used to pick up audio signals. Specifically, the pickup panel 100 may include one or more microphone units for acquiring voice signals within a conference room and converting them into audio signals in the form of electrical signals. The audio signal can be a raw analog signal or a signal that has undergone pre-amplification or preliminary processing within the pickup panel 100.

[0021] The first host 200 is physically separated from the pickup panel 100, and the first host 200 is used to receive and process audio signals and obtain an output signal. The first host 200 may contain audio processing circuitry (such as an amplifier, analog-to-digital converter, digital signal processor, etc.) for amplifying, filtering, echo cancellation, noise suppression, mixing, and other processing of the audio signals from the pickup panel 100, and finally outputting an audio signal that can be used for subsequent amplification, recording, or network transmission.

[0022] In this embodiment, "physically separated" means that the pickup panel 100 and the first host 200 are spatially independent and not integrated into the same housing. There is no direct rigid connection or shared structural components between them; electrical connection and signal transmission are achieved only through the transmission cable 300. Specifically, "physically separated" includes, but is not limited to, the following three meanings: 1) Independent housing packaging: The microphone panel 100 and the first host 200 each have independent housings, and they can be installed in different physical locations. The microphone panel 100 is generally fixed to the ceiling 20 of the conference room, while the first host 200 can be flexibly arranged inside the ceiling 20, above the suspended ceiling, in the equipment cabinet, in the control room, or other locations away from the microphone panel 100 as needed.

[0023] 2) No direct mechanical coupling: Apart from the transmission cable 300, there are no rigid or elastic mechanical connections (such as screws, clips, brackets, etc.) between the two. Therefore, the vibrations generated when the first host 200 is working (such as the power frequency vibration of the power transformer, the airflow excitation of the cooling fan, the micro-vibration of the circuit board, etc.) will not be transmitted to the pickup panel 100 through the structure, thus physically isolating the mechanical noise from interfering with the pickup unit.

[0024] 3) Detachable deployment flexibility: Both can be installed, disassembled, or replaced independently according to the actual scenario. Maintenance or upgrades of the pickup panel 100 do not require touching the primary host 200, and vice versa. This provides a foundation for the maintainability and scalability of the system.

[0025] Compared to an "integrated setup": A traditional all-in-one ceiling microphone system 10 encapsulates the pickup unit, signal processing circuit, power module, etc., all within a single housing, referred to as an "integrated setup" or "all-in-one structure." In this integrated or all-in-one structure, circuit noise (such as electromagnetic interference and power ripple) and mechanical vibration (such as transformer hum) within the first host 200 are directly coupled to the pickup unit, degrading sound quality. Furthermore, because both are integrated into the same housing, the overall weight of the ceiling microphone system 10 is significant, requiring greater stability in the mounting structure.

[0026] The transmission cable 300 connects the pickup panel 100 and the first host 200 to transmit audio signals to the first host 200. The transmission cable 300 can be a shielded twisted pair cable, coaxial cable, USB cable, or Ethernet cable, etc., and its length can be flexibly selected according to the actual installation distance.

[0027] Mounting assembly 400 is used to detachably mount the microphone panel 100 to the ceiling 20. The mounting assembly 400 in this embodiment has a constrained state and a released state. (See reference...) Figures 3 to 6 Under constrained conditions, the mounting assembly 400 restricts the displacement of the pickup panel 100 relative to the ceiling 20. That is, the pickup panel 100 is fixed to the ceiling 20 and will not move relative to it due to environmental vibrations, thereby avoiding the introduction of structural noise. Please refer to [reference needed]. Figure 2 and Figure 5 In the released state, the mounting component 400 releases the displacement restriction of the pickup panel 100 relative to the ceiling 20, that is, the pickup panel 100 can be separated from the ceiling 20 for easy maintenance, replacement or rearrangement.

[0028] It should be noted that the pickup panel 100 in this embodiment may not process the audio signal, but instead transmit the audio signal to the first host 200 via the transmission cable 300, whereby the first host 200 processes the audio signal. The processing referred to here means that the pickup panel 100 does not perform complex algorithmic processing on the audio signal, including but not limited to beamforming, noise suppression, automatic mixing, and sound source localization.

[0029] It is understandable that the pickup panel 100 is responsible for converting the audio signal acquired by the microphone array into an analog-to-digital signal and sending it to the first host 200 via the transmission cable 300. The pickup panel 100 does not perform any substantial processing on the audio signal itself, nor does it alter the original acoustic characteristics of the audio signal. That is, the audio data received by the first host 200 carries the raw audio data without any processing, preserving complete sound field information (including the relative time difference, amplitude difference, and phase difference between each microphone channel), providing the highest quality basic data for high-precision sound source localization, adaptive beamforming, and 3D spatial audio rendering. In contrast, traditional all-in-one microphones often integrate dozens or hundreds of microphone units, an internal DSP processor, and complex algorithms (including those for beamforming, noise suppression, automatic mixing, and sound source localization). Once the audio stream processed by its internal DSP is output, no subsequent device can obtain the original microphone array audio data, thus preventing secondary localization or more advanced spatial audio rendering. The pickup panel 100 of this application only outputs the raw multi-channel audio data of the picked-up audio. It does not contain a digital signal processor (DSP) or algorithm module for performing mixing, noise reduction, sound source localization, beamforming, and echo cancellation on the picked-up audio. The first host 200 can dynamically select to use simple automatic mixing or run complex audio algorithms according to actual needs, or even forward the raw audio data to a third-party processing platform, demonstrating great application flexibility.

[0030] The mounting assembly 400 is configured to detachably mount the microphone panel 100 to the ceiling 20. The mounting assembly 400 has a constrained state and a released state. This mounting assembly 400 allows for easy installation, removal, and maintenance of the microphone panel 100 while ensuring its stability in the mounting position. In the constrained state, the mounting assembly 400 securely fixes the microphone panel 100 to the ceiling 20, thereby limiting the displacement of the microphone panel 100 relative to the ceiling 20. The microphone panel 100 will not move relative to the ceiling due to environmental vibrations, thus avoiding the introduction of structural noise. In the released state, the mounting assembly 400 releases the displacement restriction on the microphone panel 100, meaning the microphone panel 100 can be moved or removed relative to the ceiling 20 to facilitate installation, maintenance, or replacement operations. As one feasible implementation, when maintenance is required, the user switches the mounting assembly 400 from the constrained state to the released state and removes the microphone panel 100 from the ceiling 20 without the need for complex tools or destructive operations. This detachability improves system maintainability without sacrificing aesthetics and robustness. In summary, this embodiment of the application physically separates the pickup panel 100 from the first host 200 and connects them via a transmission cable 300. This allows the pickup panel 100 to be independently deployed at a pickup location on the ceiling 20, while the first host 200 can be flexibly placed in other locations (e.g., inside or near the ceiling 20). On one hand, this architecture keeps the pickup panel 100 away from potential interference sources such as processing circuits and power modules in the first host 200, physically isolating circuit noise from coupling to the front-end audio signal, thus helping to maintain a high signal-to-noise ratio and high fidelity of the original audio signal. On the other hand, since the first host 200 no longer needs to be integrated with the pickup panel 100 in the same housing, it can be deployed nearby according to the actual wiring conditions, thereby shortening the transmission path of audio signals (especially unamplified analog signals) and reducing the risk of interference and attenuation during transmission. Even if the transmission cable 300 has a certain length, balanced transmission or digital transmission can be used to further improve anti-interference capabilities, and the split design provides a structural basis for such optimization. Furthermore, the split design allows for flexible adjustment of the number, position, and angle of the pickup panels 100 according to the actual acoustic structure of the conference room (such as room size, reverberation time, and background noise source location), thereby optimizing the pickup coverage, reducing blind spots, improving far-field sensitivity, and suppressing environmental reverberation, thus improving the overall sound quality at the system level.

[0031] Based on this, the mounting component 400 enables detachable installation between the microphone panel 100 and the ceiling 20 by switching between a constrained state and a released state. In the constrained state, the mounting component 400 restricts the displacement of the microphone panel 100 relative to the ceiling 20, ensuring installation stability during long-term use; in the released state, the displacement restriction is lifted, allowing the microphone panel 100 to be quickly removed or reinstalled. Thus, there is no need for complex permanent locking structures for stability, nor is there a need to sacrifice installation rigidity for ease of installation and removal. While ensuring stable sound pickup, maintenance operations are significantly simplified, enabling the microphone system 10 to simultaneously meet the requirements of the overall aesthetics of the conference room ceiling 20, long-term operational reliability, ease of on-site deployment and maintenance, and improved overall sound quality of the ceiling microphone system 10.

[0032] The following examples illustrate this point using specific test data: In the same conference room environment, comparing the split ceiling microphone system 10 of this application with a traditional integrated ceiling microphone, in terms of installation stability, the pickup panel 100 of this application showed no visible displacement after 72 hours of continuous operation, while the traditional integrated product, due to its greater weight, experienced a sinking of approximately 0.5mm in its mounting bracket. Regarding audio quality, the low-frequency noise in the recording of this application was reduced by approximately 6dB compared to the traditional product. In terms of disassembly and assembly, the traditional product required removing four screws and unplugging multiple internal cables, taking approximately 15 minutes, while the pickup panel 100 of this application could be removed simply by rotating it approximately 30 degrees, taking approximately 10 seconds. Therefore, this application effectively overcomes the technical limitation of the traditional integrated architecture where stability and ease of disassembly / assembly are mutually exclusive while improving sound quality.

[0033] To ensure a stable installation between mounting component 400 and ceiling 20, please refer to [the relevant documentation / reference]. Figure 5 In some embodiments, the ceiling 20 is provided with a first guide channel 20a extending in a first direction, and the mounting assembly 400 is configured to be at least partially received in the first guide channel 20a of the ceiling 20. The first direction here generally refers to a direction perpendicular to the plane of the ceiling 20, i.e., a vertical direction or the thickness direction of the ceiling 20. The first guide channel 20a may be a through or semi-through channel with smooth inner walls or a guide structure. The mounting assembly 400 is configured to be at least partially received in the first guide channel 20a of the ceiling 20.

[0034] Under constrained conditions, the ceiling 20 and the mounting assembly 400 are interlocked to maintain the relative position of the mounting assembly 400 in the first guide channel 20a. For example, the mounting assembly 400 may be provided with a radially extendable latch that engages with a groove on the inner wall of the first guide channel 20a; or the mounting assembly 400 and the first guide channel 20a may be connected by an interference fit or a threaded connection.

[0035] In the released state, the ceiling 20 releases the mounting component 400 in the first guide channel 20a, allowing the pickup panel 100 to separate from the ceiling 20 along a first direction. By configuring the first guide channel and the mounting component 400 to cooperate, the pickup panel 100 achieves rapid alignment and stable locking.

[0036] In this embodiment, the first guide channel 20a provided on the ceiling 20 is a pre-set channel with a specific shape and size on the ceiling 20, mainly serving to provide a positioning and guiding space for the mounting component 400. Exemplarily, the first guide channel 20a can be a slot pre-reserved on the ceiling 20, and its cross-sectional shape can be rectangular, circular, etc., without limitation, to accommodate different mounting components 400. The mounting component 400 is configured to be at least partially accommodated in the first guide channel 20a of the ceiling 20, thus ensuring that the mounting component 400 can be aligned and connected with the ceiling 20, providing a structural basis for subsequent interlocking and releasing operations between the two.

[0037] In the constrained state, the ceiling 20 and the mounting assembly 400 interlock to maintain the relative position of the mounting assembly 400 in the first guide channel 20a. This provides a secure fixation of the pickup panel 100 to the ceiling 20, preventing accidental displacement or detachment during normal use. In the released state, the ceiling 20 releases the mounting assembly 400 from the first guide channel 20a, allowing the pickup panel 100 to separate from the ceiling 20 along a first direction. This allows for easy removal of the pickup panel 100 from the ceiling 20 for maintenance, replacement, or repositioning.

[0038] Through the above technical solution, a first guide channel 20a extending in a first direction is provided on the ceiling 20, and the mounting component 400 is at least partially accommodated in the first guide channel 20a, thereby providing a structured feature for the installation and removal of the pickup panel 100, avoiding the inconvenience of fixing and removing the pickup panel 100, enabling maintenance personnel to easily remove the pickup panel 100 without complicated tools, simplifying the process of later maintenance and replacement, and improving the maintainability of the system.

[0039] For convenient and reliable control of locking and releasing of the mounting component 400 in the first guide channel 20a, please refer to [link / reference needed]. Figures 3 to 6In some embodiments, the ceiling microphone system 10 further includes a locking component 500 disposed on the mounting assembly 400. The locking component 500 in this embodiment includes a reset part 510 and a locking part 520. The reset part 510 elastically acts on the locking part 520, causing the locking part 520 to switch between a locked state and an unlocked state. The reset part 510 can be an elastic element such as a spring or a sheet, elastically acting on the locking part 520, causing the locking part 520 to switch between a locked state and an unlocked state. When the locking part 520 is in the locked state, it clamps or restrains the mounting assembly 400 to maintain its relative position in the first guide channel 20a. When the locking part 520 is in the unlocked state, the ceiling 20 releases the mounting assembly 400 from the first guide channel 20a, allowing the pickup panel 100 to separate from the ceiling 20 along a first direction. This locking component 500 can automatically lock during installation and unlock manually or with tools during disassembly, further improving operational convenience.

[0040] Exemplarily, the locking component 500 in this application embodiment can be a mechanical or electromechanical device. The reset part 510, acting as an elastic element, provides a restoring force, enabling the locking part 520 to automatically return to a preset initial state without external intervention, or to return to a stable state after the external force is released. The reset part 510 provides an elastic force to the locking part 520 through compression, stretching, or bending deformation, allowing the locking part 520 to switch between a locked and unlocked state, thereby achieving the fixing or release of the mounting component 400.

[0041] In the locked state, the locking part 520 in the locking assembly 500 forms an effective fixing or limiting engagement with the mounting assembly 400, thereby limiting the relative displacement of the mounting assembly 400 in the first guide channel 20a. When the locking part 520 is in the locked state, the locking part 520 limits the movement of the mounting assembly 400 in the first guide channel 20a along the first direction by clamping or restraining (e.g., snapping, embedding, or pressing) the mounting assembly 400. That is, it can maintain the relative position of the mounting assembly 400 in the first guide channel 20a and keep the mounting assembly 400 in a constrained state. This can limit the displacement of the pickup panel 100 relative to the ceiling 20, that is, the pickup panel 100 is fixed to the ceiling 20 and will not move relative to the ceiling due to environmental vibration, thereby avoiding the introduction of structural noise.

[0042] In the locked state, the locking part 520 in the locking assembly 500 is released from its fixed or limiting engagement with the mounting assembly 400, thereby allowing the mounting assembly 400 to move relative to the first guide channel 20a, and thus enabling the pickup panel 100 to separate from the ceiling 20. In the unlocked state, the clamping or restraining effect of the locking part 520 on the mounting assembly 400 is released, allowing the mounting assembly 400 to move freely, thus releasing the displacement restriction of the pickup panel 100 relative to the ceiling 20. This facilitates the separation of the pickup panel 100 from the ceiling 20 for maintenance, replacement, or rearrangement.

[0043] Through the above technical solution, a locking component 500 is introduced into the ceiling microphone system 10. The locking component 500, through the elastic action of the reset part 510 and the locking part 520, realizes the reliable locking and convenient unlocking of the mounting component 400 in the first guide channel 20a. This avoids the problem of the mounting component 400 being not securely fixed or inconvenient to disassemble when only the first guide channel 20a is available. This makes the disassembly and maintenance of the pickup panel 100 simple and efficient, improving the availability and maintenance convenience of the system.

[0044] For a feasible implementation method, please refer to [link / reference]. Figure 5 and Figure 6 In this embodiment, the mounting component 400 can be directly mounted on the pickup panel 100, while the locking component 500 is mounted on the mounting component 400. In this example, the mounting component 400 can be constructed as a columnar frame, such as a circular or square column, whose outer contour matches the first guide channel 20a of the ceiling 20, allowing it to be inserted into the first guide channel 20a. The locking component 500 can be constructed as a spring-loaded latch structure, where the reset part 510 can be a torsion spring mounted on the columnar frame, and the locking part 520 is a spring plate whose axis is mounted on the columnar frame along with the torsion spring. One torsion arm of the torsion spring abuts against the spring plate, while the other torsion arm abuts against the inside of the columnar frame and against the pickup panel 100.

[0045] The spring-loaded column is aligned with the first guide channel 20a of the ceiling 20 and pushed in. During insertion, the spring piece (locking part 520) is compressed by the first guide channel 20a, forcing it to overcome the force of the torsion spring (reset part 510) and retract towards the center of the column. When the spring piece has completely passed through the ceiling 20, the compressive force on the spring piece disappears, and the spring piece quickly springs outward under the elastic restoring force stored in the torsion spring, with its end locking onto the back of the ceiling 20. At this point, the spring piece cannot retract on its own, thereby limiting the displacement of the column and the connected pickup panel 100 pulled out along the first direction, achieving the locking state of the locking part 520, thus constraining the mounting assembly 400, and ultimately limiting the displacement of the pickup panel 100 relative to the ceiling 20.

[0046] When disassembly is required, the spring is usually pressed inward manually or with a tool to overcome the spring force of the torsion spring and retract until its outer contour retracts into the outer contour of the column frame; or, the pickup panel 100 is pulled away from the ceiling 20, and the spring (locking part 520) is automatically retracted into the outer contour of the column frame (mounting assembly 400) and disengaged by the pressure of the edge of the ceiling 20. At this time, the contact between the spring (locking part 520) and the back of the ceiling 20 is released, and the locking part 520 is in the unlocked state. Thus, the mounting assembly 400 is in the released state, and the pickup panel 100 can slide smoothly out along the first guide channel 20a. After disassembly is completed, the pickup panel 100 is separated from the ceiling 20.

[0047] It should be noted that the mounting component 400 and the locking component 500 in this example can move along the first guide channel 20a as a whole, which facilitates the fine-tuning of the mounting component 400 during assembly and disassembly, ensuring that the pickup panel 100 fits tightly against the ceiling 20.

[0048] In practical applications, to ensure flexible connection between the mounting component 400 and the pickup panel 100, or to simplify the disassembly and installation steps of the entire mounting component 400 when maintenance, replacement, or adjustment of the pickup panel 100 is required, thereby improving operational efficiency and convenience, please refer to... Figure 7In some embodiments, the mounting assembly 400 includes a base 410 and a mounting portion 420. In this embodiment, the base 410 is used to be fixed to the first guide channel 20a, and the mounting portion 420 is detachably coupled to the base 410. The mounting portion 420 is connected to the pickup panel 100. In this embodiment, the base 410 is a component of the mounting assembly 400, and its main function is to provide a stable pre-installed structure that can be fixed to the first guide channel 20a of the ceiling 20. Exemplarily, the base 410 can be a frame structure fixed within the first guide channel 20a, for example, by bolts, rivets, or clips.

[0049] In this embodiment, by dividing the mounting assembly 400 into a base 410 and a mounting part 420, and enabling a detachable connection between the two, the installation and maintenance process of the ceiling microphone system 10 can be simplified. The base 410 is configured to be fixed to the first guide channel 20a of the ceiling 20, that is, when the base 410 is fixed to the ceiling 20, the base 410 can serve as a relatively stable mounting interface on the ceiling 20.

[0050] When the pickup panel 100 needs to be installed on the ceiling 20, first connect the pickup panel 100 to the mounting part 420, and then detachably engage the mounting part 420 with the pickup panel 100 connected to it with the base 410, which is already fixed to the ceiling 20. Under constrained conditions, the base 410 and the mounting part 420 are interlocked, thereby limiting the displacement of the pickup panel 100 relative to the ceiling 20, ensuring the stable installation of the pickup panel 100, and preventing relative movement due to environmental vibrations, thus avoiding the introduction of structural noise. When maintenance, replacement, or adjustment of the pickup panel 100 is required, simply release the detachable engagement between the mounting part 420 and the base 410, allowing the mounting part 420 to enter a released state. The pickup panel 100, along with the mounting part 420, can then be separated from the base 410, while the base 410 remains fixed to the ceiling 20. This allows the pickup panel 100 to be separated from the base 410 for easy maintenance, replacement, or rearrangement.

[0051] The above technical solution, which adopts a split design for the mounting component 400, makes the disassembly and installation of the pickup panel 100 more convenient, eliminating the need to operate the entire mounting component 400 each time, thus improving the modularity and maintainability of the ceiling microphone system 10. On the other hand, it also allows the mounting component 400 to better adapt to the structure of the first guide channel 20a of the ceiling 20. Pre-installed on the ceiling 20 via the base 410, it provides a fixing function, ensuring the stability and reliability of the entire system on the ceiling 20. The interlocking of the base 410 and the mounting part 420 under constrained conditions ensures the positional accuracy and installation rigidity of the pickup panel 100 on the ceiling 20, effectively suppressing the transmission of structural vibrations caused by loose installation to the pickup unit, thereby reducing structural noise interference with the audio signal and contributing to improving the overall sound quality of the ceiling microphone system 10.

[0052] To ensure that the pickup panel 100 can be stably and reliably secured or released during installation or maintenance, please refer to... Figure 7 In some embodiments, the base 410 is provided with a second guide channel 410a extending along a first direction, and the mounting portion 420 can be at least partially accommodated in the second guide channel 410a. In a constrained state, the base 410 and the mounting portion 420 are locked together to maintain the relative position of the mounting portion 420 in the second guide channel 410a. In a released state, the base 410 releases the mounting portion 420 in the second guide channel 410a, allowing the pickup panel 100 to be separated from the ceiling 20 along the first direction.

[0053] In this embodiment, the second guide channel 410a provided on the base 410 is a channel with a specific shape and size pre-set on the base 410, mainly serving to provide a positioning and guiding space for the mounting part 420. Exemplarily, the second guide channel 410a can be a slot pre-reserved on the base 410, and its cross-sectional shape can be rectangular, circular, etc., without limitation, to adapt to different mounting parts 420. The mounting part 420 is configured to be at least partially accommodated in the second guide channel 410a of the base 410, thus ensuring that the mounting part 420 can be aligned and connected with the base 410, providing a structural basis for subsequent interlocking and releasing operations. For example, the second guide channel 410a can be a U-shaped groove, and the mounting part 420 has a corresponding protruding structure. The mounting portion 420 can be at least partially accommodated in the second guide channel 410a, that is, a part or most of the mounting portion 420 can be surrounded or restricted by the second guide channel 410a, thereby realizing relative movement guidance and position fixation between the base 410 and the mounting portion 420.

[0054] Under constrained conditions, the base 410 and the mounting part 420 are locked together to maintain the relative position of the mounting part 420 in the second guide channel 410a. It should be noted that "locking" in this embodiment refers to generating an interaction force between the base 410 and the mounting part 420 through mechanical, magnetic, or other physical means, thereby preventing or restricting the movement of the mounting part 420 relative to the base 410 in the second guide channel 410a. For example, the base 410 may be provided with a slot, and the mounting part 420 may be provided with an elastic latch. When the mounting part 420 is inserted into the second guide channel 410a and reaches a predetermined position, the elastic latch engages with the slot, achieving locking.

[0055] In the released state, the base 410 releases the mounting portion 420 in the second guide channel 410a, allowing the pickup panel 100 to separate from the ceiling 20 along the first direction. It should be noted that "release" in this embodiment refers to releasing the locking state between the base 410 and the mounting portion 420, allowing the mounting portion 420 to move freely within or be removed from the second guide channel 410a. Specifically, with the mounting portion 420 in the released state, the pickup panel 100 can be removed from the ceiling 20 along the first direction, i.e., the extending direction of the second guide channel 410a.

[0056] With the mounting part 420 in the released state, it can also move upward along the first direction to connect with the pre-installed base 410 on the ceiling 20, so that the pickup panel 100 can be connected to the ceiling 20. During installation, the mounting part 420 slides into the base 410 along the second guide channel 410a, and then the mounting part 420 is firmly fixed in a preset relative position within the second guide channel 410a by the interlocking between the base 410 and the mounting part 420, thereby constraining the mounting part 420.

[0057] When the pickup panel 100 needs maintenance or replacement, the locking between the base 410 and the mounting part 420 is released, and the mounting part 420 is put into a released state. At this time, the mounting part 420 can be smoothly removed from the base 410 along the second guide channel 410a, thereby separating the pickup panel 100 from the ceiling 20 in the first direction.

[0058] Through the above technical solution, on the one hand, the mutual locking between the base 410 and the mounting part 420 under the constraint state, and the guidance and limiting of the mounting part 420 by the second guide channel 410a, ensure the positional accuracy and installation rigidity of the pickup panel 100 on the ceiling 20, effectively suppress the transmission of structural vibration caused by loose installation to the pickup unit, reduce the interference of structural noise on the audio signal, and help improve the overall sound quality of the ceiling microphone system 10; on the other hand, it effectively solves the problem that the installation may be unstable or the disassembly may be inconvenient if only a detachable fit is provided, and simplifies the installation and maintenance operation of the pickup panel 100.

[0059] Based on the technical solution of the mounting assembly 400 including a base 410 and a mounting portion 420, in order to ensure the reliability of the locking between the mounting portion 420 and the base 410, and to quickly realize the locking and unlocking between the mounting portion 420 and the base 410, in some embodiments, the ceiling microphone system 10 further includes a locking assembly 500 disposed on the base 410 or the mounting portion 420. The locking assembly 500 includes a reset portion 510 and a locking portion 520. The reset portion 510 elastically acts on the locking portion 520 so that the locking portion 520 switches between a locked state and an unlocked state. In the locked state, the locking portion 520 clamps or restrains the mounting portion 420 to maintain the relative position of the mounting portion 420 in the second guide channel 410a. In the unlocked state, the base 410 releases the mounting portion 420 in the second guide channel 410a, so that the pickup panel 100 can be separated from the ceiling 20 along a first direction.

[0060] It should be noted that, unlike the embodiment described above where the locking component 500 is directly connected to the mounting component 400 of the column frame, the locking component 500 in this example is connected to the base 410 or the mounting part 420.

[0061] In this embodiment, by providing a locking component 500 on the base 410 or the mounting portion 420, and utilizing the switching between a locking and unlocking state of the locking portion 520, the mounting portion 420 and the locking portion 520 are locked and released. This allows the mounting component 400 to switch between a constrained state and a released state, enabling the mounting portion 420 to be relatively fixed or move freely within the second guide channel 410a. On one hand, this avoids the risk of the pickup panel 100 loosening, shaking, or even falling off due to accidental vibration, impact, or gravity, thus improving the installation stability and safety of the microphone system 10. On the other hand, when maintenance, replacement, or adjustment is required, switching the locking portion 520 from the locked state to the unlocked state allows the base 410 to quickly release the mounting portion 420, enabling the pickup panel 100 to smoothly separate from the ceiling 20 along the first direction, simplifying the disassembly process and improving operational efficiency and convenience.

[0062] Similar to the locking component 500 described above, the locking component 500 in this example can also be constructed as a spring snap structure. The reset part 510 and the locking part 520 in this example can be implemented in the same way as the reset part 510 and the locking part 520 described above. For example, both can use a torsion spring as the reset part 510 and a spring sheet as the locking part 520. Of course, the locking component 500 in this example can also be implemented in other ways. For example, the locking component 500 can be constructed as a claw structure (not shown in the figure). The claw structure includes a claw and an elastic arm. The locking part 520 is constructed as a claw, and the reset part 510 is constructed as an elastic arm. The elastic arm drives the claw to engage or disengage from the mounting part 420 through deformation. In this way, locking and releasing between the mounting part 420 and the locking part 520 can be realized, thereby enabling the mounting part 420 to change its displacement within the second guide channel 410a provided in the base 410, and to exit from the second guide channel 410a. In this way, the pickup panel 100 can remain relatively stationary relative to the ceiling 20 or move relative to the ceiling 20 to form a connection or separation with the ceiling 20.

[0063] The following describes, by way of two specific examples, the reset part 510 and the locking part 520 included in the locking component 500 and the base 410 and the mounting part 420 included in the mounting component 400 in the application embodiments.

[0064] As one feasible implementation, the reset part 510 is configured as a torsion spring, the locking part 520 is configured as a spring sheet, the base 410 is configured as a column frame, the mounting part 420 is configured as a column frame adapted to the internal contour of the column frame, and the locking component 500 is provided on the base 410.

[0065] When the mounting part 420 moves along the second guide channel 410a to a preset position relative to the base 410, the outer wall of the mounting part 420 contacts the spring and continuously compresses it, causing the spring to overcome the torsion of the torsion spring and retract into the column frame (base 410). When the mounting part 420 continues to move until it fully reaches the preset position, the compressive force from the outer wall of the mounting part 420 disappears, and the elastic restoring force stored in the torsion spring drives the spring to quickly eject radially outward, causing its end to abut against the base 410, forming a mechanical interlock. Thus, the mounting part 420 is firmly locked in the preset position of the base 410 and cannot be withdrawn in the opposite direction along the second guide channel 410a. The entire mounting assembly 400 is in a constrained state, and the pickup panel 100 is stably mounted.

[0066] As another feasible implementation, the base 410 can also be a metal guide rail extending along a first direction, the guide rail having a T-shaped cross-section and being fixed within the first guide channel 20a of the ceiling 20. The mounting part 420 can be a slider that mates with the T-shaped guide rail, the slider having a T-shaped groove and being able to slide along the guide rail. The pickup panel 100 can be fixed to the bottom of the slider by screws. To achieve a detachable fit between the base 410 and the mounting part 420, a spring-loaded latch can be provided on the slider. When the slider slides along the guide rail to a preset position, the latch can automatically pop out and engage with a preset hole on the guide rail, thereby locking the mounting part 420 onto the base 410, forming a constrained state. When release is required, the latch can be disengaged from the preset hole by using an external tool or by manually pressing it, thereby releasing the lock, allowing the mounting part 420 to slide along the guide rail and separate from the base 410, entering a released state.

[0067] For another method of achieving a detachable connection between the base 410 and the mounting part 420, please refer to [link / reference needed]. Figure 7 and Figure 8 In some embodiments, the base 410 is provided with a second guide channel 410a extending along a first direction, and the mounting portion 420 can be at least partially accommodated in the second guide channel 410a. The mounting portion 420 in this embodiment includes a mating member 421 and a connecting member 422. The mating member 421 is connected to one of the base 410 and the pickup panel 100, and the connecting member 422 is connected to the other of the base 410 and the pickup panel 100.

[0068] In this configuration, one of the mating member 421 and the connecting member 422 is configured to rotate relative to the other to a mating position, thereby constraining the mounting portion 420. One of the mating member 421 and the connecting member 422 is also configured to rotate relative to the other to a disengaged position, thereby releasing the mounting portion 420.

[0069] In this embodiment of the application, as described above, the second guide channel 410a provided on the base 410 is a channel with a specific shape and size that is preset on the base 410. Its main function is to provide a positioning and guiding space for the mounting part 420, ensuring that the mounting part 420 can be aligned and connected with the base 410, and providing a structural basis for the subsequent mutual locking and releasing operations of the two.

[0070] The mounting portion 420 in this embodiment includes a mating member 421, which is connected to one of the base 410 and the pickup panel 100. The mating member 421 is one of the components that enables a rotatable connection between the mounting portion 420 and the base 410. Its function is to interact with the connecting member 422, completing engagement or disengagement through relative rotation. The connecting member 422 included in the mounting portion 420 is connected to the other of the base 410 and the pickup panel 100. The connecting member 422 is a component that interacts with the mating member 421, and its function is to provide rotational and limiting space for the mating member 421, thereby enabling the mounting portion 420 to switch between a constrained state and a released state. Exemplarily, the mating member 421 refers to a protruding structure, such as a lug, pin, locking block, or a flange with a specific shape. The connecting member 422 refers to a groove structure, such as an L-shaped groove, spiral groove, locking groove, or a hole with a specific shape.

[0071] One of the mating member 421 and the connecting member 422 is configured to rotate relative to the other to a mating position, thereby constraining the mounting portion 420. The relative rotation between them allows the mating member 421 and the connecting member 422 to form a connection, thus firmly fixing the mounting portion 420 to the base 410 and limiting the displacement of the mounting portion 420 relative to the base 410. In this embodiment, the mating position refers to the position where the mating member 421 and the connecting member 422 form an effective locking engagement through relative rotation. In the mating position, a stable mechanical lock (e.g., by snap-fit ​​or hook-fit) is formed between the mating member 421 and the connecting member 422, thereby firmly fixing the mounting portion 420 in the base 410, constraining the mounting assembly 400, and limiting the displacement of the pickup panel 100 relative to the ceiling 20. It should be noted that the rotation of the mating part 421 and the connecting part 422 can be achieved by manually rotating the mounting part 420, or by using an external tool to drive a specific part of the mounting part 420 or the base 410 to rotate. In this way, the relative rotation of the mating part 421 and the connecting part 422 can be achieved.

[0072] One of the mating member 421 and the connecting member 422 is also configured to rotate relative to the other to a separated position, so that the mounting portion 420 is in a released state. In this embodiment, the separated position refers to the position where the mating member 421 and the connecting member 422 are released from their locking engagement through relative rotation. In the separated position, the mating member 421 and the connecting member 422 rotate relative to each other to the separated position, the connection between them is released, thereby allowing the mounting portion 420 to detach from the base 410 and releasing the displacement restriction on the pickup panel 100.

[0073] The connection between mating part 421 and connector 422 can be achieved by snap-fit ​​or hook-fit, depending on the actual configuration, and will not be elaborated further.

[0074] In this embodiment, the mounting portion 420 of the mounting assembly 400 is rotatably connected to the base 410, enabling convenient and reliable installation and removal between the microphone panel 100 and the ceiling 20. The base 410 has a second guide channel 410a extending in a first direction, providing a path for the mounting portion 420 to be inserted and guided. The mounting portion 420 includes a mating member 421 and a connecting member 422, which are respectively connected to one of the base 410 and the microphone panel 100 and configured to rotate relative to each other. When the mounting portion 420 is inserted into the second guide channel 410a, it can be rotated from a separated position to a mating position by rotating one of the mating member 421 and the connecting member 422 relative to the other. In the mating position, the mating part 421 and the connecting part 422 form a stable mechanical lock, for example, by snapping or hooking together, thereby firmly fixing the mounting part 420 in the base 410, so that the entire mounting assembly 400 is in a constrained state, effectively limiting the displacement of the pickup panel 100 relative to the ceiling 20. When it is necessary to remove the pickup panel 100, simply rotate the mating part 421 and the connecting part 422 to the separation position to release the lock between them, so that the mounting assembly 400 is in a released state, thereby allowing the pickup panel 100 to be easily separated from the ceiling 20 in the first direction.

[0075] Through the above technical solution, the installation part 420 achieves the switching between the constrained state and the released state by the relative rotation of the mating part 421 and the connecting part 422. On the one hand, the mechanical locking formed by the mating part 421 and the connecting part 422 in the mating position ensures the positional accuracy and installation rigidity of the pickup panel 100 on the ceiling 20, effectively suppresses the transmission of structural vibration caused by loose installation to the pickup unit, reduces the interference of structural noise on the audio signal, and helps to improve the overall sound quality of the ceiling microphone system 10. On the other hand, it simplifies the installation and disassembly operations, which can be completed without complicated tools, improving the efficiency and convenience of operation.

[0076] In some embodiments, please refer to Figure 8 The mating part 421 includes a mating body 4211 and a mating portion 4212 that protrudes radially along the second guide channel 410a; the connecting part 422 includes a connecting body 4221 and a connecting portion 4222; in the mating position, the mating portion 4212 and the connecting portion 4222 form a limiting fit.

[0077] In this embodiment, the mating member 421 is a component of the mounting portion 420, responsible for mating with the connecting member 422 to achieve constraint or release of the mounting portion 420. The mating body 4211 refers to the main structure of the mating member 421, which carries other functional components of the mating member 421. Exemplarily, the mating body 4211 can be a cylindrical or square structure, typically made of metal or high-strength plastic. The mating portion 4212 is a structure protruding outward along the radial direction of the second guide channel 410a on the mating member 421, and is a key part for achieving a limiting fit with the connecting member 422. Exemplarily, the mating portion 4212 can be designed as a protrusion, flange, pin, or toothed structure, etc., and its shape and size should ensure that it can engage with the corresponding structure of the connecting member 422 during mating, thereby providing a reliable limiting effect. For example, the mating part 4212 may be one or more radially protruding flaps or an annular protrusion, the shape and size of which should ensure that it can engage with the corresponding structure of the connector 422 during mating, thereby providing a reliable limiting effect.

[0078] The connector 422 is another component of the mounting portion 420, working in conjunction with the mating part 421 to constrain or release the mounting portion 420. The connecting body 4221 refers to the main structure of the connector 422, supporting other functional components of the connector 422. It can be, for example, a sleeve with an inner cavity or a structure with a groove, typically made of a material similar to the mating body 4211. The connecting portion 4222 is a structure on the connector 422 used for limiting engagement with the mating portion 4212 of the mating part 421. The connecting portion 4222 is typically designed to accommodate or engage the mating portion 4212, for example, it can be one or more grooves, holes, limiting walls, or snap-fit ​​structures. Its shape and size should match the shape and size of the mating portion 4212 to form a stable mechanical interlock in the mating position. For example, the flange of the mating portion 4212 can be blocked by the limiting wall of the connecting portion 4222, thereby achieving limiting.

[0079] The limiting fit between the mating part 421 and the connecting part 422 refers to the structural interaction between the mating part 4212 and the connecting part 4222, which restricts their relative movement through physical contact or mechanical interlocking to prevent unnecessary displacement of the pickup panel 100 when the mounting assembly 400 is in a constrained state. The limiting fit can take various forms such as locking, embedding, clamping, or wedging. For example, the mating part 4212 can be locked into the groove of the connecting part 4222, or the flange of the mating part 4212 can be blocked by the limiting wall of the connecting part 4222.

[0080] In this embodiment, during the installation of the ceiling microphone system 10, when the mounting portion 420 of the mounting component 400 is constrained, the mating portion 4212 of the mating member 421 and the connecting portion 4222 of the connecting member 422 can form a clear and reliable limiting fit. Through this technical solution, on the one hand, it effectively avoids situations where stable fixation cannot be ensured solely through relative rotation, significantly enhancing the installation stability of the pickup panel 100 on the ceiling 20, ensuring the positional accuracy and installation rigidity of the pickup panel 100, effectively suppressing the transmission of structural vibrations caused by loose installation to the pickup unit, reducing structural noise interference with the audio signal, and helping to improve the overall sound quality of the ceiling microphone system 10. On the other hand, the limiting fit between the mating portion 4212 and the connecting portion 4222 can resist external vibrations or minor impacts, preventing the pickup panel 100 from accidentally loosening or falling off during long-term use, thereby improving the safety and reliability of the system. Furthermore, the clear limiting fit also provides users with clear feedback on the installation being in place, simplifying the installation operation and improving the user experience.

[0081] In some embodiments, the mounting assembly 400 further includes a gasket (not shown in the figures). In this embodiment, the gasket is located between the base 410 and the ceiling 20. The gasket surrounds at least a portion of the base 410 along the axial direction of the first guide channel 20a.

[0082] In this embodiment, the gasket can be made of a flexible or semi-flexible material used to fill the gap between two objects, and its main function is to provide cushioning, sealing, vibration damping, or tolerance compensation. The gasket can be made of various materials, such as rubber, silicone, foam plastic, cork, or fiber materials, depending on the required function and environmental conditions. For example, rubber gaskets have good elasticity and sealing properties, making them suitable for applications requiring vibration damping and dust protection. Foam gaskets, on the other hand, have the advantages of being lightweight and able to fill irregular gaps.

[0083] By placing a gasket between the base 410 and the ceiling 20, the gasket can directly act between the base 410 and the ceiling 20, filling the gap between them. On the one hand, the elastic deformation of the gasket compensates for dimensional tolerances or surface unevenness of the openings in the ceiling 20, thereby ensuring a tight fit between the base 410 and the ceiling 20 and preventing wobbling between them. On the other hand, it can also effectively dampen vibrations transmitted from the ceiling 20 or the surrounding environment to the pickup panel 100, reducing the occurrence of resonance. In addition, the gasket can also play a sealing role to a certain extent, preventing dust or moisture from entering the interior of the installation structure.

[0084] By having a gasket surround at least a portion of the base 410 along the axial direction of the first guide channel 20a, that is, by having the gasket spatially extend along the direction of the first guide channel 20a around at least a portion of the periphery of the base 410, this technical solution ensures that the gasket can provide support and function for the contact area between the base 410 and the ceiling 20, rather than merely providing localized contact. For example, the gasket can be designed to be annular or frame-shaped to conform to the shape of the base 410 and cover its edge that contacts the ceiling 20. On the one hand, the elastic deformation of the gasket can compensate for the dimensional tolerances or surface unevenness of the opening in the ceiling 20, ensuring a tight fit between the base 410 and the ceiling 20, preventing wobbling between them, and thus ensuring the installation stability of the pickup panel 100. On the other hand, the gasket can effectively dampen the vibration transmitted from the ceiling 20 or the surrounding environment to the pickup panel 100, suppress the transmission of structural vibration to the pickup unit, reduce the interference of structural noise on the audio signal, and help improve the overall sound quality of the ceiling microphone system 10. In addition, the gasket can also play a sealing role to a certain extent, preventing dust or moisture from entering the interior of the installation structure.

[0085] To facilitate user confirmation of whether the mating part 421 and the connecting part 422 have been rotated into place, in some embodiments, the microphone system 10 further includes a detection element (not shown in the figure) for detecting the relative position of the mating part 421 and the connecting part 422.

[0086] The detection element in this embodiment is a component used to sense and output the relative position information between the mating part 421 and the connecting part 422, and can provide status feedback between the mating part 421 and the connecting part 422 to confirm whether the mounting assembly 400 is in a constrained or released state. The detection element in this embodiment can be implemented using various technologies. For example, it can be a microswitch or limit switch; when the mating part 421 or the connecting part 422 rotates to a specific position, its mechanical contacts are triggered, thereby outputting an electrical signal to indicate the current position. Alternatively, the detection element can be a photoelectric sensor, which determines the relative position of the mating part 421 and the connecting part 422 by detecting the obstruction or reflection of a light beam. For example, a reflective mark is set on the mating part 421, and a photoelectric sensor is set on the connecting part 422; when the mark enters the sensor's detection range, it indicates that a specific position has been reached. Of course, in other examples, the detection element can be a magnetic induction sensor, such as a Hall sensor or a reed switch; when a magnet set on the mating part 421 or the connecting part 422 approaches or moves away from the sensor, the sensor outputs a signal to indicate the relative position. Alternatively, capacitive or inductive sensors can be used to determine relative position by detecting changes in capacitance or inductance.

[0087] Through the above technical solution, a detection element is introduced into the ceiling microphone system 10. This detection element is configured to monitor the relative position of the mating part 421 and the connecting part 422. During installation, when the mating part 421 and the connecting part 422 reach the mating position through relative rotation, the detection element can accurately sense this mechanical alignment or locking state and immediately generate a corresponding electrical signal. Similarly, when the mating part 421 and the connecting part 422 rotate to the separation position, the detection element can also detect this separation state and output a different signal. This signal can be used by the system to drive indicator lights, issue sound prompts, or as part of control logic to confirm that the pickup panel 100 has been safely constrained to the ceiling 20, or has been completely released from constraint and can be safely disassembled. This technical solution effectively combines mechanical action with electronic feedback, providing users with intuitive and reliable status confirmation to improve the accuracy and safety of the installation process and avoid the risk of insecure installation or accidental detachment due to misjudgment or improper operation. On the other hand, the real-time monitoring of the constraint status of the installation component 400 by the detection component ensures that the pickup panel 100 maintains the correct installation position on the ceiling 20, reduces changes in the pickup angle caused by positional deviation, helps maintain the pickup quality of the pickup panel 100, and thus improves the overall sound quality of the ceiling microphone system 10.

[0088] To facilitate convenient and non-damaging disassembly and installation between the pickup panel 100 and the base 410, in some embodiments, the mounting part 420 includes a magnetic attractor (not shown in the figures). In this embodiment, the magnetic attractor is disposed at least one of the base 410 and the pickup panel 100, and is used to provide magnetic attraction between the base 410 and the pickup panel 100.

[0089] In this embodiment, the magnetic attractor is constructed as a component capable of generating a magnetic field and applying a magnetic force. The magnetic attractor can be implemented in various forms to suit different installation scenarios. Exemplarily, the magnetic attractor can be one or more permanent magnets, such as neodymium iron boron magnets or ferrite magnets, which provide a continuous attraction force through their inherent magnetic field. In other feasible implementations, the magnetic attractor can also be an electromagnet, generating or eliminating the magnetic field by controlling the on / off state of the current, thereby achieving a controllable attraction force.

[0090] For example, a magnetic attractor can be disposed on the base 410, while a corresponding magnetic material, such as an iron sheet or a ferromagnetic alloy, is disposed on the pickup panel 100. Conversely, a magnetic attractor can also be disposed on the pickup panel 100, while a corresponding magnetic material is disposed on the base 410. In another implementation, magnetic attractors can be disposed on both the base 410 and the pickup panel 100, for example, by the attraction of opposite magnetic poles.

[0091] Through the above technical solution, in the ceiling microphone system 10, a magnetic connector is used to connect the pickup panel 100 to the base 410. On the one hand, this simplifies the installation and removal process of the pickup panel 100, allowing users to quickly fix and remove it without any tools, thus improving operational convenience. On the other hand, the magnetic connection avoids wear and damage that may be caused by repeated insertion, removal, or tightening of mechanical parts, extending the service life of the pickup panel 100. Furthermore, the magnetic connector provides a stable and reliable magnetic force, ensuring the stability of the pickup panel 100 under constraint, effectively preventing accidental detachment, thereby improving the overall safety and reliability of the system.

[0092] To achieve reliable and convenient locking and unlocking between the mounting section 420 and the base 410, while avoiding visible damage to the mounting structure or requiring complex special tools, please refer to... Figure 9 In some embodiments, the mounting portion 420 includes a magnetic rotating member 424, a transmission steering member 425, and a fastener 426. In this embodiment, the magnetic rotating member 424 is rotatably mounted on the pickup panel 100 and can rotate around a first axis under the drive of an external rotating magnetic field. The transmission steering member 425 in this embodiment is in transmission cooperation with the magnetic rotating member 424 and can rotate around a second axis, which intersects the first axis. The fastener 426 in this embodiment is connected to the transmission steering member 425.

[0093] When the magnetic rotating component 424 rotates under the drive of an external rotating magnetic field, it drives the fastener 426 to move through the transmission steering component 425, so that the fastener 426 is locked or separated from the base 410, so that the mounting component 400 is in a constrained state or a released state.

[0094] The magnetic rotating component 424 in this embodiment refers to a component capable of rotation under the action of an external rotating magnetic field, rotatably disposed inside or on the back of the pickup panel 100. The magnetic rotating component 424 can be made of a permanent magnet material, such as a magnetic alloy or sintered magnet, and is designed with a specific magnetic pole distribution for effective coupling with an external magnetic field. Alternatively, the magnetic rotating component 424 can also be a non-magnetic material structure with embedded permanent magnets, such as multiple permanent magnets embedded in a plastic or metal matrix. In this example, the magnetic rotating component 424 is typically rotatably disposed inside or on the back of the pickup panel 100, and its axis of rotation (i.e., the first axis) can be parallel to the surface of the pickup panel 100.

[0095] In this embodiment, the transmission steering component 425 refers to a mechanical part used to transmit and convert the rotational motion of the magnetic rotating component 424 into the desired motion direction of the fastener 426. This transmission steering component 425 can engage with the magnetic rotating component 424 through transmission mechanisms such as gear meshing, friction transmission, or chain / belt transmission. The rotation axis (second axis) of the transmission steering component 425 intersects with the first axis of the magnetic rotating component 424, thereby achieving a change in the direction of motion. For example, when the magnetic rotating component 424 rotates horizontally, the transmission steering component 425 can convert it into vertical rotation or linear motion.

[0096] In this embodiment, the fastener 426 refers to a component that directly locks or separates from the base 410, used to achieve a constrained or released state of the mounting assembly 400. The fastener 426 can be connected to the transmission steering component 425, for example, through a threaded connection, a pin connection, or integral molding. When the fastener 426 moves, it can connect to or disengage from the base 410. Exemplarily, the movement of the fastener 426 can be rotational (e.g., a screw) or linear (e.g., a pin).

[0097] In this embodiment, the first axis of the magnetic rotating member 424 intersects the second axis of the transmission steering member 425, meaning that the rotation center lines of the magnetic rotating member 424 and the transmission steering member 425 respectively intersect at a point in space. This technical solution enables the transmission steering member 425 to effectively receive the rotational torque of the magnetic rotating member 424 and convert it into movement in different directions (e.g., perpendicular to the first axis), thereby driving the fastener 426 to perform locking or disengagement operations with the base 410.

[0098] In a constrained state, the pickup panel 100 is fixed to the ceiling 20 by first aligning and initially engaging the mounting part 420 with the base 410. Then, an external rotating magnetic field acts on the magnetic rotating member 424 inside the pickup panel 100, causing it to rotate around a first axis. The rotational motion of the magnetic rotating member 424 is transmitted through the transmission steering member 425 and converted into the motion of the fastener 426. Since the second axis of the transmission steering member 425 intersects the first axis of the magnetic rotating member 424, the external rotation operation can effectively drive the fastener 426 to move in the desired direction (e.g., perpendicular to the pickup panel 100). When the fastener 426 moves to the position where it is locked with the base 410, the mounting assembly 400 is in a constrained state, thereby limiting the displacement of the pickup panel 100 relative to the ceiling 20. The pickup panel 100 is firmly fixed to the ceiling 20 and will not move relative to the ceiling due to environmental vibrations, thus avoiding the introduction of structural noise.

[0099] In the released state, when the pickup panel 100 is about to be removed from the ceiling 20, the magnetic rotating component 424 is driven to rotate in the opposite direction by the external rotating magnetic field. The transmission steering component 425 drives the fastener 426 to move to the position separated from the base 410. At this time, the mounting component 400 is in the released state, and the pickup panel 100 can be removed from the ceiling 20 for maintenance, replacement or rearrangement.

[0100] Through the above technical solution, the ceiling microphone system 10 achieves non-contact locking and separation of the mounting component 400 between the pickup panel 100 and the ceiling 20. This avoids exposing operating components on the ceiling 20, improving overall aesthetics. Furthermore, utilizing an external rotating magnetic field to drive the internal mechanical structure makes operation more convenient and discreet, suitable for installation environments at heights or difficult to access directly. Additionally, small holes can be provided in the ceiling 20, the base 410 can be placed inside these holes, and the fastener 426 included in the mounting part 420 can be rotated by the transmission steering component 425 under the action of the magnetic rotating component 424, thus achieving locking and separation between the base 410 and the fastener 426. No operating holes are needed on the front or bottom of the microphone; all operations are completed discreetly on the side, ensuring the installation stability of the pickup panel 100 on the ceiling 20, effectively suppressing the transmission of structural vibrations caused by loose installation to the pickup unit, reducing structural noise interference with the audio signal, and contributing to improved overall sound quality of the ceiling microphone system 10.

[0101] In some embodiments, the drive steering member 425 is configured as a worm gear or helical gear that meshes with the magnetic rotating member 424. The fastener 426 in this embodiment is a screw or bolt. The base 410 in this embodiment is provided with a nut or threaded hole that mates with the fastener 426.

[0102] In this embodiment, the transmission steering component 425 is constructed as a worm gear or helical gear meshing with the magnetic rotating component 424. Both of these gear transmission methods can effectively transmit and steer rotational motion. A worm gear is a gear that meshes with a worm to transmit and steer rotational motion. It typically has a large transmission ratio and self-locking characteristics; that is, when the worm gear is subjected to a reverse torque, the worm is difficult to be driven in the opposite direction, thus providing additional locking stability. A helical gear is a gear whose teeth are at a certain angle to the axis, enabling effective transmission and steering of rotational motion. Exemplarily, the transmission steering component 425 can use a worm gear or helical gear meshing with the magnetic rotating component 424 to ensure that the rotational torque of the magnetic rotating component 424 can be efficiently and stably transmitted to the fastener 426, thereby achieving precise locking or disengagement operations.

[0103] In this embodiment, the fastener 426 is a screw or bolt. Screws are typically used to connect thinner components or are directly screwed into threaded holes, while bolts are often used in conjunction with nuts to connect two or more components through holes. A reliable threaded connection is formed by the engagement of the nut or threaded hole with the screw or bolt's threads. Bolts offer advantages such as simple structure, reliable connection, and easy disassembly, providing a stable axial clamping force to ensure a secure connection between the pickup panel 100 and the base 410.

[0104] In this embodiment, the base 410 is provided with a nut or threaded hole that mates with the fastener 426. The nut is a part with internal threads and is used in conjunction with a bolt; the threaded hole is an internally threaded hole directly machined on the base 410 body and is used in conjunction with a screw. By adopting the technical solution of threaded engagement between the nut or threaded hole and the screw or bolt, a reliable threaded connection is formed. When the fastener 426 moves, it can provide precise positioning and stable locking force, ensuring that the pickup panel 100 will not undergo accidental displacement under constrained conditions.

[0105] Through the above technical solution, the transmission steering component 425 uses a worm gear or helical gear to mesh with the magnetic rotating component 424, and the fastener 426 forms a threaded connection with the nut or threaded hole on the base 410. On the one hand, the entire mounting assembly 400 can provide a strong clamping force under the constrained state, effectively limiting the displacement of the pickup panel 100 relative to the ceiling 20, ensuring the positional accuracy and installation rigidity of the pickup panel 100, effectively suppressing the transmission of structural vibration caused by loose installation to the pickup unit, reducing the interference of structural noise on the audio signal, and helping to improve the overall sound quality of the ceiling microphone system 10; on the other hand, it can quickly release the constraint in the released state, ensuring the installation stability and operation convenience of the microphone system 10.

[0106] Please continue to refer to this. Figure 9 In some embodiments, the mounting assembly 400 further includes a support 440 and a preload 450. In this embodiment, the support 440 has a support space 440a accommodating a portion of the fastener 426, and the support 440 is connected between the drive steering member 425 and the fastener 426. In this embodiment, the preload 450 is located within the support space 440a, and between the fastener 426 and the drive steering member 425. The preload 450 is configured to provide a preload force to the fastener 426, causing the fastener 426 to tend to move towards the base 410.

[0107] In this embodiment, the support member 440 has a support space 440a accommodating a portion of the fastener 426 and is connected between the transmission steering member 425 and the fastener 426. The main function of the support member 440 in this example is to provide precise motion guidance for the fastener 426, ensuring that the fastener 426 can move stably and smoothly during locking or unlocking. Simultaneously, the support member 440 also provides a restricted installation and operating area for the preload member 450. As one implementation, the support member 440 can be designed as a sleeve-like structure with an inner cavity through which a portion of the fastener 426 (e.g., a rod) can slide; alternatively, the support member 440 can also be a frame with a specific geometry, guiding and supporting the fastener 426 through its internal channels or holes.

[0108] In this embodiment, the preload 450 is located within the support space 440a and between the fastener 426 and the drive steering member 425. In this example, the preload 450 is configured to provide a preload force to the fastener 426, causing the fastener 426 to tend to move towards the base 410. The function of the preload 450 is to provide a continuous elastic force to the fastener 426 to ensure that the fastener 426 can tightly press against the base 410 in the locked state, thereby preventing loosening of the connection due to factors such as vibration, temperature changes, or material creep. For example, the preload 450 can be a helical compression spring that is compressed when the fastener 426 is driven to the locked position, thereby generating a continuous axial force; or, the preload 450 can be an elastic washer, such as a disc spring or wave spring, which provides the required preload force through its own elastic deformation.

[0109] In the aforementioned ceiling microphone system 10, when an external rotating magnetic field drives the magnetic rotating component 424 to rotate, the magnetic rotating component 424 drives the fastener 426 to move via the transmission steering component 425, thereby locking or separating the fastener 426 from the base 410. Under constrained conditions, the external rotating magnetic field drives the magnetic rotating component 424 to rotate, and the magnetic rotating component 424 drives the fastener 426 towards the base 410 via the transmission steering component 425, ultimately locking it in place. The preload component 450 is compressed, generating a continuous elastic preload force, which consistently causes the fastener 426 to maintain its tendency to move towards the base 410, pressing the fastener 426 and base 410 together. This restricts the displacement of the pickup panel 100 relative to the ceiling 20, ensuring the pickup panel 100 is securely fixed to the ceiling 20 and will not move relative to environmental vibrations, thus avoiding the introduction of structural noise. In the released state, the magnetic rotating component 424 rotates in the opposite direction, driving the fastener 426 to move to a position separated from the base 410 via the transmission steering component 425. The mounting component 400 releases the displacement restriction of the pickup panel 100 relative to the ceiling 20, and the pickup panel 100 can be removed from the ceiling 20 for maintenance, replacement or rearrangement.

[0110] By introducing the support member 440 and the pre-tightening member 450, this embodiment effectively solves the problems of insufficient locking force, easy loosening, and inability to provide a continuous and stable pre-tightening force that may result from relying solely on the fastener 426 for direct locking. On the one hand, the continuous pre-tightening force provided by the pre-tightening member 450 ensures that the connection between the fastener 426 and the base 410 remains tight, effectively compensating for manufacturing tolerances and material creep, and resisting the loosening tendency caused by external vibrations. This ensures the positional accuracy and installation rigidity of the pickup panel 100, effectively suppresses the transmission of structural vibrations to the pickup unit, reduces the interference of structural noise on the audio signal, and helps improve the overall sound quality of the ceiling microphone system 10. On the other hand, the support member 440 provides precise guidance for the movement of the fastener 426 and provides a stable operating platform for the pre-tightening member 450, making the entire locking mechanism more reliable and durable. Therefore, the pickup panel 100 in this embodiment can be securely and reliably installed on the ceiling 20 to improve the overall stability and service life of the microphone system 10, ensure the quality of audio signal pickup, and the long-term operational reliability of the equipment.

[0111] As another feasible embodiment of the connection between the pickup panel 100 and the base 410, based on the aforementioned embodiment of the mounting assembly 400 including the base 410 and the mounting portion 420, please continue to refer to... Figure 10In this embodiment, the mounting portion 420 includes a fastener 426. The fastener 426 is rotatably connected to the pickup panel 100. The fastener 426 is configured to rotate about its own axis under the drive of an external rotating magnetic field, so that the mounting assembly 400 is in a constrained or released state. In this embodiment, the base 410 is mounted on the side of the ceiling 20 near the pickup panel 100, and the base 410 has a fastening opening adapted to the fastener 426. The fastening opening in this embodiment refers to a hole in the base 410 adapted to the fastener 426, used to form a physical connection or separation with the fastener 426, thereby switching the mounting assembly 400 between a constrained and released state.

[0112] In this embodiment, the fastener 426 is a mechanical component used to connect or fix two or more parts, forming a physical connection or separation with a fastening opening provided on the base 410 through its own movement. The fastener 426 can take various forms, such as screws, bolts, clips, or cam locks. The fastener 426 is configured to be rotatably connected to the pickup panel 100, meaning that while maintaining connection with the pickup panel 100, the fastener 426 can rotate relative to the pickup panel 100. The rotational movement of the fastener 426 is achieved by driving an external rotating magnetic field. This external rotating magnetic field can be generated by a specialized magnetic tool (e.g., a screwdriver with a magnetic tip), which couples magnetically with the magnetic portion of the fastener 426 (e.g., magnetic material embedded in the head of the fastener 426 or the fastener 426 itself being made of magnetic material), thereby causing the fastener 426 to rotate synchronously when the tool rotates. In some other feasible implementations, a rotating magnetic field generator can be externally positioned to sense the magnetic elements inside the fastener 426 to generate a rotational torque.

[0113] In this embodiment, the rotation of the fastener 426 around its own axis refers to the circumferential movement of the fastener 426 around its central axis. The rotation of the fastener 426 allows the mounting assembly 400 to be in either a constrained or released state. In the constrained state, an external rotating magnetic field drives the fastener 426 to rotate around its own axis, forming a stable connection between the fastener 426 and the fastening opening on the base 410. The mounting assembly 400 restricts the displacement of the pickup panel 100 relative to the ceiling 20, ensuring the pickup panel 100 is securely fixed to the ceiling 20 and preventing relative movement due to environmental vibrations, thus avoiding the introduction of structural noise. In the released state, the external rotating magnetic field drives the fastener 426 to rotate in the opposite direction, disengaging the fastener 426 from the fastening opening. The mounting assembly 400 releases the displacement restriction of the pickup panel 100 relative to the ceiling 20, allowing the pickup panel 100 to be removed from the ceiling 20 for maintenance, replacement, or rearrangement.

[0114] Through the above technical solution, on the one hand, the installation and disassembly process of the ceiling microphone system 10 can be simplified, making it suitable for pickup panels 100 installed on ceilings 20 that are high up or difficult to access directly. On the other hand, it can also avoid the inconvenience that traditional mechanical operations may cause and the potential impact on the appearance of the ceiling 20, improving the maintainability of the system and the user experience. Furthermore, since the fastener 426 is configured to be rotatably connected to the pickup panel 100, it is ensured that the fastener 426 will not be lost during disassembly, further improving the overall reliability and convenience of the system. On the other hand, the stable connection formed by the fastener 426 and the fastening opening on the base 410 ensures the positional accuracy and installation rigidity of the pickup panel 100 on the ceiling 20, effectively suppressing the transmission of structural vibrations caused by loose installation to the pickup unit, reducing the interference of structural noise on the audio signal, and helping to improve the overall sound quality of the ceiling microphone system 10.

[0115] As another feasible embodiment of the connection between the pickup panel 100 and the base 410, based on the aforementioned embodiment of the mounting assembly 400 including the base 410 and the mounting portion 420, please refer to... Figures 11 to 18 In this embodiment, the base 410 is provided with a second guide channel 410a extending along a first direction, and the mounting portion 420 can be at least partially accommodated in the second guide channel 410a. In this embodiment, the mounting portion 420 is provided with a fixing member 428, which is fixedly connected to the pickup panel 100 and configured to rotate relative to the base 410. The microphone system 10 in this example also includes a locking assembly 500 connected between the fixing member 428 and the base 410. The locking assembly 500 includes a reset part 510 and a locking part 520. The reset part 510 elastically acts on the locking part 520 so that the locking part 520 switches between a locked state and an unlocked state. The fixing member 428 can rotate relative to the base 410 by a first angle, so that the locking part 520 rotates relative to the base 410 to a locked position. The reset part 510 provides a first force to the locking part 520, so that the locking part 520 has a tendency to move toward the base 410, so that the locking part 520 is in a locked state, thereby limiting the displacement of the pickup panel 100 relative to the ceiling 20. In this embodiment, the fixing member 428 can rotate relative to the base 410 by a second angle, causing the locking part 520 to rotate relative to the base 410 to the unlocked position. The base 410 provides a second force to the locking part 520, causing the locking part 520 to have a tendency to move away from the base 410, so that the locking part 520 is in the unlocked state, thereby releasing the displacement restriction of the pickup panel 100 relative to the ceiling 20.

[0116] In this embodiment of the application, as described above, the second guide channel 410a provided on the base 410 is a channel with a specific shape and size that is preset on the base 410. Its main function is to provide a positioning and guiding space for the mounting part 420, ensuring that the mounting part 420 can be aligned and connected with the base 410, and providing a structural basis for the subsequent mutual locking and releasing operations of the two.

[0117] In this embodiment, the fastener 428 is a component of the mounting portion 420, which connects the pickup panel 100 to the locking assembly 500, allowing the user to control the state of the locking assembly 500 by rotation. In this example, the fastener 428 is constructed as a ring structure to adapt to different installation scenarios.

[0118] In this example, the locking component 500 is a part that enables switchable locking between the mounting part 420 and the base 410. The reset part 510 is an elastic element that provides a continuous elastic force to drive the locking part 520 to maintain a tight fit with the base 410 in the locked state. Common reset parts 510 may include coil springs, leaf springs, torsion springs, or elastic rubber pads, the choice of which depends on the required elastic force and space constraints.

[0119] In this example, the locking part 520 is a component that mechanically engages with the base 410 to achieve locking. The locking part 520 in this example can be constructed as a protrusion, pin, latch, pawl, or a block with a specific shape, so as to reliably restrict the displacement of the mounting part 420 in the locked state and allow it to disengage smoothly in the unlocked state.

[0120] In this embodiment, the rotation of the fixing member 428 at the first or second angle refers to the rotation operation of the fixing member 428 relative to the base 410. The working state of the locking assembly 500 is switched by a preset rotation angle. For example, the first angle can be 30 degrees, indicating a rotation of 30 degrees from the initial position to the locked position; the second angle can be -30 degrees, that is, a rotation of 30 degrees in the opposite direction from the locked position to the unlocked position. The rotation operation provides users with an intuitive and effortless locking and unlocking method. In this example, the locked position refers to the state where the locking part 520 and the base 410 are mechanically interlocked. At this time, the first force provided by the reset part 510 pushes the locking part 520 towards the base 410, ensuring that the mounting part 420 is firmly fixed. In this example, the unlocked position refers to the state where the mechanical interlock between the locking part 520 and the base 410 is released. At this time, the second force provided by the base 410 to the locking part 520 pushes the locking part 520 away from the base 410, allowing the mounting part 420 to move or separate freely.

[0121] In this embodiment, the first force is provided by the reset part 510, and its direction is to cause the locking part 520 to engage with the base 410, thereby achieving locking. The second force is applied to the locking part 520 by the structure of the base 410 (e.g., inclined surface, guide groove) during the rotation of the fixing member 428, and its direction is to cause the locking part 520 to move away from the base 410, thereby achieving unlocking. The synergy of these two forces ensures the reliability and smoothness of the locking and unlocking process.

[0122] When the microphone panel 100 is fixed to the ceiling 20 under constrained conditions, the mounting portion 420 is inserted into the second guide channel 410a of the base 410, and part of the fixing member 428 is also located within the second guide channel 410a. Subsequently, the operator rotates the fixing member 428 to a first angle, and the rotation of the fixing member 428 causes the locking portion 520 to move to a locking position that cooperates with the base 410. In the locking position, the reset portion 510 elastically acts on the locking portion 520, providing a first force towards the base 410, so that the locking portion 520 and the base 410 are tightly engaged, thereby firmly constraining the mounting portion 420 within the base 410, so that the mounting assembly 400 is in a constrained state, thereby limiting the displacement of the microphone panel 100 relative to the ceiling 20 from relative movement due to environmental vibration, thus avoiding the introduction of structural noise.

[0123] In the released state, the operator rotates the fixing member 428 by a second angle. This rotation causes the locking part 520 to move from the locked position to the unlocked position. During the unlocking process, the base 410 applies a second force to the locking part 520 away from the tendency of the base 410 to move, overcoming the elastic force of the reset part 510, and pushing the locking part 520 out of its engagement with the base 410, thereby releasing the displacement restriction on the mounting part 420, so that the pickup panel 100 can be easily removed from the ceiling 20 for maintenance, replacement or rearrangement.

[0124] Through the above technical solution, this application embodiment provides a simple, reliable, and smooth installation method for the microphone panel 100, allowing users to quickly switch between constrained and released states. On one hand, the rotation operation of the fixing member 428 is intuitive and effortless, enabling users to quickly switch between constrained and released states. The elastic force provided by the reset part 510 ensures a tight fit between the locking part 520 and the base 410 in the locked state, effectively preventing accidental detachment of the microphone panel 100, improving system safety, and ensuring the positional accuracy and installation rigidity of the microphone panel 100. This effectively suppresses the transmission of structural vibrations caused by loose installation to the microphone unit, reduces structural noise interference with the audio signal, and helps improve the overall sound quality of the ceiling microphone system 10. On the other hand, during the unlocking process, the second force applied by the base 410 to the locking part 520 ensures that the locking part 520 can smoothly disengage, avoiding jamming and improving the convenience of maintenance and disassembly.

[0125] To ensure reliable locking and unlocking between the locking part 520 and the base 410, and to prevent inaccurate positioning or accidental loosening from affecting the stability and safety of the installation, please refer to the following: Figure 17 and Figure 18 In some embodiments, the inner wall surface of the base 410 has a latching portion 411. In the locked position, the locking portion 520 latches with the latching portion 411; in the unlocked position, the locking portion 520 is released from the latching portion 411.

[0126] In this embodiment, the latching part 411 is a structure provided on the inner wall surface of the base 410. Its function is to form a mechanical engagement with the locking part 520 to achieve positioning and limiting of the locking part 520. The latching of the locking part 520 and the latching part 411 means that when the mounting assembly 400 is in a constrained state, the locking part 520 is tightly engaged with the latching part 411 on the inner wall surface of the base 410 through mechanical contact to restrict the relative movement of the locking part 520 relative to the base 410, thereby firmly fixing the mounting part 420 in the base 410, and thus restricting the displacement of the pickup panel 100 relative to the ceiling 20.

[0127] The release of the locking part 520 from the latching part 411 means that when the mounting assembly 400 is in the released state, the mechanical engagement between the locking part 520 and the latching part 411 on the inner wall of the base 410 is released, so that the locking part 520 is no longer limited by the latching part 411, thereby allowing the mounting part 420 to move relative to the base 410, thereby releasing the displacement restriction of the pickup panel 100 relative to the ceiling 20, so that it can be disassembled.

[0128] Through the above technical solution, on the one hand, a reliable locking and unlocking solution can be provided for the mounting component 400 of the ceiling microphone system 10. This allows the locking part 520 to be positioned and physically limited by the latching part 411 in the locked state, effectively enhancing the stability and safety of the pickup panel 100 installation, ensuring the positional accuracy and installation rigidity of the pickup panel 100, effectively suppressing the transmission of structural vibrations caused by loose installation to the pickup unit, reducing structural noise interference with the audio signal, and helping to improve the overall sound quality of the ceiling microphone system 10. On the other hand, in the unlocked state, the separation of the locking part 520 from the latching part 411 ensures that the mounting component 400 can be smoothly and conveniently released from constraints, improving the efficiency of maintenance and disassembly, thereby enhancing the installation reliability and user experience of the entire ceiling microphone system 10.

[0129] To ensure that the locking part 520 can smoothly and accurately enter or disengage from the latching part 411, thereby achieving stable and reliable locking and convenient unlocking, please refer to the following: Figure 17 and Figure 18 In some embodiments, the latching portion 411 includes a limiting groove 411a and a guide surface 411b communicating with the limiting groove 411a. The locking portion 520 is configured to slide into or out of the limiting groove 411a along the guide surface 411b to a preset position when the fixing member 428 rotates relative to the base 410.

[0130] In this embodiment, the limiting groove 411a is part of the snap-fit ​​portion 411. Its main function is to accommodate and fix the locking portion 520 in the locked state, preventing the locking portion 520 from moving relative to the base 410, thereby constraining the mounting assembly 400. Exemplarily, the limiting groove 411a can be a recess whose shape matches the locking portion 520, such as a rectangular groove, V-shaped groove, or U-shaped groove; it can also be a hole into which the locking portion 520 is inserted. It should be noted that the depth and width of the limiting groove 411a need to provide sufficient limiting effect in the locked state, while allowing the locking portion 520 to disengage smoothly during unlocking.

[0131] In this embodiment, the guide surface 411b is part of the snap-fit ​​portion 411. Its main function is to guide the locking portion 520 to smoothly and accurately slide into or out of the limiting groove 411a when the fixing member 428 rotates relative to the base 410. In this example, the guide surface 411b can avoid direct collision or jamming between the locking portion 520 and the limiting groove 411a. Exemplarily, the guide surface 411b can be an inclined surface, such as a ramp-like structure, to guide the locking portion 520 to gradually enter or leave the limiting groove 411a; it can also be an arc surface to provide a smooth transition, depending on different installation scenarios.

[0132] The locking part 520 is configured to slide into or out of the limiting groove 411a along the guide surface 411b to a preset position when the fixing member 428 rotates relative to the base 410, ensuring that the engagement process between the locking part 520 and the snap-fit ​​part 411 is controlled and smooth. When the fixing member 428 rotates, the locking part 520 moves along a predetermined trajectory. The guide surface 411b guides the locking part 520 to the entrance of the limiting groove 411a and allows it to slide smoothly into the groove until it reaches the preset locking position. The mounting assembly 400 restricts the displacement of the pickup panel 100 relative to the ceiling 20. The pickup panel 100 is firmly fixed to the ceiling 20 and will not move relative to the ceiling due to environmental vibration, thereby avoiding the introduction of structural noise. Conversely, when the fixing part 428 is rotated in the opposite direction to unlock, the guide surface 411b will also guide the locking part 520 to slide out of the limiting groove 411a and release the jamming, so as to avoid misalignment, jamming or damage between the locking part 520 and the jamming part 411 during installation or disassembly, thereby improving the convenience of operation and the reliability of the system.

[0133] For example, the guide surface 411b is constructed as a guide ramp, and the area of ​​the guide ramp gradually decreases from the limiting groove 411a in a direction away from the limiting groove 411a in the first direction. In this way, when the locking part 520 is in the unlocked position, it is possible to allow the mounting part 420 and its provided fastener 428 to be separated from the base 410.

[0134] Through the above technical solution, a limiting groove 411a and a guide surface 411b are provided in the locking part 411. On the one hand, this solves the problems of jamming, misalignment, or difficulty in precise alignment that may occur during the engagement of the locking part 520 and the locking part 411. The presence of the guide surface 411b provides a smooth transition path for the locking part 520 to enter and exit, improving the smoothness and reliability of locking and unlocking operations. On the other hand, the positioning and limiting of the locking part 520 by the limiting groove 411a ensures the positional accuracy and installation rigidity of the pickup panel 100, effectively suppressing the transmission of structural vibrations caused by loose installation to the pickup unit, reducing structural noise interference with the audio signal, and helping to improve the overall sound quality of the ceiling microphone system 10. Furthermore, it also avoids component damage that may occur due to improper operation, thereby extending the service life of the microphone system 10 and ensuring the stability of the pickup panel 100 under constrained conditions.

[0135] To ensure the microphone panel 100 is flush with the ceiling surface 20 or to achieve the desired embedding effect, please refer to [the relevant documentation / reference]. Figure 17 and Figure 18 In some embodiments, the microphone system 10 also includes an adjustment structure 700. In this example, the adjustment structure 700 is disposed on the base 410 to adjust the position of the base 410 relative to the ceiling 20 in the thickness direction of the ceiling 20.

[0136] In this embodiment, the adjustment structure 700 refers to a component disposed on the base 410 for adjusting the position of the base 410 relative to the ceiling 20 in the thickness direction. For example, the adjustment structure 700 can be a screw; by rotating the screw, the depth to which it is screwed into the base 410 can be changed, thereby adjusting the position of the base 410 in the thickness direction of the ceiling 20 to accommodate ceilings 20 of different thicknesses or actual installation requirements.

[0137] Through the above technical solution, the ceiling microphone system 10 of this application can flexibly adjust the position of the base 410 relative to the ceiling 20 in the thickness direction of the ceiling 20. On the one hand, it can adapt to ceilings 20 of different thicknesses, or precisely adjust the installation depth of the pickup panel 100 according to actual installation needs. This ensures that the pickup panel 100 is flush with the surface of the ceiling 20 after installation, or reaches the expected embedding depth, thereby improving the installation accuracy, aesthetics, and integration with the architectural environment of the system. On the other hand, it can also avoid installation difficulties or poor appearance caused by mismatch in ceiling 20 thickness.

[0138] Please continue to refer to this. Figure 17 and Figure 18 In some embodiments, the adjustment structure 700 includes an adjustment member 710, which is adjustable in axial position along the base 410 to adjust the position of the base 410 relative to the ceiling 20 in its thickness direction.

[0139] In this embodiment, the adjusting member 710 is a movable component in the adjusting structure 700. The adjusting member 710 is engaged with the base 410, and the position of the base 410 relative to the ceiling 20 is adjusted by adjusting the axial position of the adjusting member 710 along the base 410. Exemplarily, the adjusting member 710 in this example can be a threaded sleeve, a movable pad, a slider with a groove, etc., to achieve the adjustment of the axial position of the adjusting member 710 along the base 410. No specific limitation is made in this embodiment.

[0140] It should be noted that the adjustable member 710 is axially adjustable along the base 410, meaning that the adjustable member 710 can move and be fixed in the direction of the central axis of the base 410. For example, the adjustable member 710 can rotate along the thread of the base 410 or slide on the guide rail of the base 410. By adjusting the position of the base 410 relative to the ceiling 20 in its thickness direction, the depth of the base 410 in the opening of the ceiling 20 can be changed, so that the edge of the base 410 is flush with the surface of the ceiling 20, or protrudes or recesses a certain distance according to actual installation requirements.

[0141] Through the above technical solution, when the adjusting member 710 moves axially along the base 410, it can change the effective working distance between the base 410 and the ceiling 20, allowing the base 410 to be depth-adjusted according to the actual thickness of the ceiling 20. On the one hand, when the adjusting member 710 moves axially along the base 410, it can change the effective working distance between the base 410 and the ceiling 20, thereby allowing the base 410 to be depth-adjusted according to the actual thickness of the ceiling 20. For example, by rotating or sliding the adjusting member 710, it can be moved outward or inward, thereby clamping the ceiling 20 material between the adjusting member 710 and another fixed part of the base 410. On the other hand, the precise adjustment of the axial position of the base 410 by the adjusting member 710 ensures the installation rigidity of the pickup panel 100 on the ceiling 20, effectively suppressing the transmission of structural vibrations caused by improper installation to the pickup unit, reducing structural noise interference with the audio signal, and helping to improve the overall sound quality of the ceiling microphone system 10.

[0142] Please continue to refer to this. Figure 17 and Figure 18 In some embodiments, the adjustment structure 700 further includes a limiting member 720. In this embodiment, the limiting member 720 is located on the side of the ceiling 20 near the pickup panel 100. The limiting member 720 is connected to the base 410 and, together with the adjustment member 710, clamps the ceiling 20 to fix the base 410 at least along the thickness direction of the ceiling 20 in the first guide channel 20a.

[0143] In this embodiment, the limiting member 720 is located on the side of the ceiling 20 near the pickup panel 100, connected to the base 410, and together with the adjusting member 710, clamps the components of the ceiling 20. Its main function is to act directly on the lower surface of the ceiling 20, forming an effective clamping of the ceiling 20 with the adjusting member 710 located above the ceiling 20. This technical solution allows the limiting member 720 to act directly on the lower surface of the ceiling 20, forming an effective clamping of the ceiling 20 with the adjusting member 710 located above the ceiling 20, thereby ensuring the fixation of the base 410 in the thickness direction of the ceiling 20.

[0144] By adjusting at least one of the adjusting member 710 and the limiting member 720, a clamping force can be generated between them on the ceiling 20, thereby firmly fixing the ceiling 20 to the base 410. Ultimately, the clamping action of the limiting member 720 and the adjusting member 710 on the ceiling 20 effectively restrains the displacement of the base 410 in the vertical direction (i.e., the thickness direction) of the ceiling 20, thus fixing the base 410 at least along the thickness direction of the ceiling 20 in the first guide channel 20a. This technical solution ensures the stable installation of the base 410 within the first guide channel 20a, preventing it from loosening or shifting due to vibration or external forces, ensuring the high stability of the base 410 in the vertical direction, and guaranteeing the installation stability of the pickup panel 100. This effectively suppresses the generation and transmission of structural noise, thereby significantly improving the sound quality performance of the ceiling microphone system 10. Furthermore, stable installation also extends the service life of the equipment and reduces maintenance needs that may arise due to loosening, improving the reliability of the system.

[0145] In some embodiments, the microphone system 10 further includes a safety rope (not shown in the figures). The safety rope in this embodiment is used to connect the pickup panel 100 to the joists of the ceiling 20.

[0146] By connecting the microphone panel 100 to the ceiling 20 joists via a safety rope, an independent and redundant mechanical connection is provided when the mounting components 400 of the microphone panel 100 (such as the base 410, mounting part 420, locking component 500, etc.) are unable to effectively restrain the microphone panel 100 for various reasons (e.g., maintenance in the released state, accidental loosening, or damage). Even if the mounting components 400 are in the released state or malfunction, the safety rope can limit the displacement of the microphone panel 100, preventing it from completely detaching from the ceiling 20 and falling. In this way, it is ensured that the microphone panel 100 always remains connected to the ceiling 20 during installation, maintenance, or accidental events, ensuring the safety of personnel and equipment below, and improving the reliability and safety of the entire microphone system 10.

[0147] In some embodiments, the pickup panel 100 includes a microphone array (not shown in the figures) and a layered circuit board (not shown in the figures). The microphone array in this embodiment includes multiple microphone units arranged in an array. The layered circuit board has multiple wiring layers, the microphone array is mounted on the layered circuit board, and the signal lines of each microphone unit are led out through different wiring layers. The thickness of the pickup panel 100 ranges from greater than 6 mm to less than or equal to 10 mm.

[0148] In this embodiment, the pickup panel 100 is a component in the ceiling microphone system 10 that collects audio signals. The pickup panel 100 can be designed in various shapes, such as circular, square, or rectangular, to adapt to different ceiling 20 designs and aesthetic requirements. A microphone array refers to multiple microphone units arranged in a predetermined geometric configuration (such as linear, circular, or planar arrays) to achieve advanced audio processing functions such as beamforming, sound source localization, and noise suppression, thereby improving the directivity and clarity of sound pickup. The microphone units included in the pickup panel 100 are components of the microphone array, responsible for converting sound waves into electrical signals, and are typically required to have high sensitivity and low noise characteristics.

[0149] In this embodiment, the layered circuit board is a printed circuit board with multiple conductive wiring layers and insulating dielectric layers. By routing on different layers, high-density interconnection can be achieved, effectively reducing the physical size of the circuit board and optimizing signal transmission paths, thereby integrating more complex circuits within a limited space. The multiple wiring layers included in the layered circuit board refer to the multiple conductive layers inside the layered circuit board, which are used to carry different signal lines, power lines, and ground lines. Properly planning these wiring layers helps isolate different signals, reduce electromagnetic interference, and provide sufficient space for complex circuit designs. Leading out signal lines through different wiring layers means that the output signal lines of each microphone unit are distributed to different wiring layers of the layered circuit board for transmission, which helps reduce crosstalk between signals and improve signal integrity, especially in high-density, multi-channel audio systems.

[0150] The thickness of the microphone panel 100 is greater than 6mm and less than or equal to 10mm. This ensures that the microphone panel 100 can maintain an ultra-thin design while meeting the installation space requirements of internal components, so that it can better integrate with the ceiling 20 and meet the requirements of modern architecture for aesthetics and concealment.

[0151] In some embodiments, the microphone panel 100 is used to convert the audio signal into a modulated signal and then send it to the first host 200 via the transmission cable 300; the first host 200 is used to receive and process the modulated signal to obtain an output signal.

[0152] In this embodiment, the pickup panel 100 modulates the acquired raw audio signal, converting it into a modulated signal. A modulated signal is a signal that loads the raw audio signal (baseband signal) onto a carrier wave, causing its characteristics (such as amplitude, frequency, and phase) to change with the audio signal. The main functions of modulation are to improve signal anti-interference capability, achieve multiplexing, adapt to the characteristics of different transmission media, and improve transmission efficiency. The pickup panel 100 can convert the audio signal into an analog modulated signal using an analog modulator, such as amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM). Then, the modulated signal is transmitted to the first host 200 via a transmission cable 300. The transmission cable 300 is the physical medium used to carry the modulated signal. Because modulated signals typically have better noise immunity and attenuation resistance, they are more suitable for long-distance or complex environment transmission via the transmission cable 300. For the transmission cable 300, coaxial cable can be selected, which has good shielding performance and is suitable for high-frequency signal transmission; twisted pair cable, such as CAT5 / 6 network cable, can also be selected, which reduces electromagnetic interference through twisting and is often used for digital signal transmission; or optical fiber can be selected, which provides extremely high bandwidth and anti-electromagnetic interference capability and is suitable for ultra-long distance and high-fidelity transmission.

[0153] As mentioned above, in this embodiment of the application, the pickup panel 100 converts the picked-up audio signal into a modulation signal and then transmits it to the first host 200 through the transmission cable 300. The first host 200 then processes the modulation signal to obtain the output signal, which effectively avoids the distortion and attenuation problems caused by interference in long-distance analog transmission of audio signals, thereby improving the stability and fidelity of audio transmission.

[0154] In some embodiments, the microphone pickup panel 100 includes an analog-to-digital converter (ADC) module and a modem module. The ADC module converts an audio signal into a first digital signal. The modem module converts the first digital signal into a modulated signal and transmits it to the first host 200 via a transmission cable 300. The ADC module is connected between the modem module and the microphone array.

[0155] In this embodiment, the analog-to-digital converter (ADC) is an electronic circuit or device that converts continuously varying analog signals (such as audio signals picked up by a microphone) into discrete digital signals. The modulation / demodulation module is responsible for converting the digital signal (the first digital signal output by the ADC) into a modulated signal suitable for transmission over the transmission cable 300. Modulation refers to the process of loading digital information onto a carrier signal so that the signal can be transmitted more stably over longer distances and resist noise interference. The modulation / demodulation module can employ pulse code modulation (PCM) or pulse width modulation (PWM) techniques to encode the digital signal into a series of pulses, where the width or position of these pulses represents the original digital information.

[0156] The analog-to-digital converter (ADC) module connects between the modem module and the microphone array, defining the sequence of signal flow. The analog audio signal picked up by the microphone array first enters the ADC module for digitization, and then the digitized audio signal (the first digital signal) enters the modem module for modulation, ultimately forming a modulated signal that is transmitted via transmission cable 300. Physical connections can be achieved through wires, pin headers, or flexible circuit boards on the circuit board, ensuring signal integrity.

[0157] Through the above technical solution, the pickup panel 100 locally completes the conversion of analog audio signals to digital signals and the modulation of digital signals. On the one hand, it enhances the anti-interference capability and transmission stability of the signal in the transmission cable 300, especially when the transmission cable 300 is long, effectively avoiding signal quality degradation caused by attenuation, noise introduction, and other factors during analog signal transmission. On the other hand, converting the signal into a modulated signal for transmission also facilitates more efficient and flexible digital signal processing by the first host 200, thereby improving the audio acquisition and processing performance of the entire ceiling microphone system 10.

[0158] The first host 200 in this embodiment can be a digital signal processor (DSP), capable of performing in-depth processing of digital signals according to digital signal processing algorithms. Digital signal processing algorithms include, but are not limited to, complex digital filtering, adaptive beamforming, acoustic echo cancellation, noise suppression, and speech enhancement algorithms, achieving high-precision processing of audio signals.

[0159] As another feasible implementation of signal transmission between the microphone panel 100 and the first host 200, in some embodiments, the microphone panel 100 is used to convert the audio signal into a standard network signal and then transmit it to the first host 200 via a transmission cable 300. The first host 200 is used to receive and process the standard network signal to obtain an output signal.

[0160] In this application embodiment, the audio signal refers to the audio collected by the microphone array, converted into an electrical signal, and then converted back into an audio signal. In this application embodiment, the standard network signal refers to a data signal conforming to a specific network communication protocol (e.g., Ethernet protocol). Standard network signals are easy to transmit and process in a network environment and can utilize existing network infrastructure.

[0161] For example, during a meeting, the microphone panel 100 is used to pick up audio signals within the meeting room. These audio signals are converted into standard network signals internally within the microphone panel 100. For instance, the microphone panel 100 can capture the speaker's voice in real time and convert it into data packets conforming to the Ethernet protocol. Subsequently, these standard network signals are transmitted to the first host 200 via transmission cable 300. As mentioned earlier, the transmission cable 300 in this example can be a standard Ethernet cable, which not only transmits data but also provides power to the microphone panel 100 via Power over Ethernet (PoE) technology, thus simplifying cabling. For example, a single Cat5e Ethernet cable can fulfill the data transmission and power supply requirements of the microphone panel 100. Furthermore, after receiving the standard network signals from the transmission cable 300, the first host 200 processes the standard network signals to obtain an output signal. Finally, the first host 200 sends the processed audio signal as an output signal to an amplifier, recording equipment, or video conferencing terminal in the meeting room for subsequent use.

[0162] In this example, the ceiling microphone system 10 uses a pickup panel 100 to convert the audio signal collected by the microphone array into an analog-to-digital converter, encapsulate it into data packets according to a standard network protocol (such as Ethernet), and then send it to the first host 200 via a transmission cable 300. The pickup panel 100 does not perform any substantial processing on the audio signal itself, nor does it alter the original acoustic characteristics of the audio signal. That is, the standard network signal received by the first host 200 carries the raw audio data without any processing, preserving complete sound field information (including the relative time difference, amplitude difference, and phase difference between each microphone channel), providing the highest quality basic data for high-precision sound source localization, adaptive beamforming, and 3D spatial audio rendering. In contrast, traditional all-in-one microphones often integrate dozens or hundreds of microphone units, an internal DSP processor, and complex algorithms (including those for beamforming, noise suppression, automatic mixing, and sound source localization). Once the audio stream processed by the internal DSP is output, no subsequent device can obtain the original microphone array audio data, thus preventing secondary localization or more advanced spatial audio rendering. In this embodiment, the pickup panel 100 only outputs the raw multi-channel audio data of the picked-up audio. It does not contain a digital signal processor (DSP) or algorithm module for performing mixing, noise reduction, sound source localization, beamforming, or echo cancellation on the picked-up audio. The first host 200 can dynamically select to use simple automatic mixing, run complex audio algorithms, or even forward the raw audio data to a third-party processing platform, demonstrating great application flexibility. To avoid redundant internal circuitry and chaotic signal processing due to unclear conversion efficiency and structural division of labor in the pickup panel 100, which would increase panel thickness and complexity, in some embodiments, the pickup panel 100 includes an audio acquisition module and a network conversion module. The audio acquisition module is used to pick up audio signals and convert them into digital signals. The network conversion module is used to convert the digital signals into standard network signals.

[0163] For example, the main function of the audio acquisition module is to convert sound wave signals from the environment into digital signals that can be processed by the electronic system. The network conversion module is responsible for encapsulating and modulating the digital signals output by the audio acquisition module, converting them into standard network signals that conform to standard network protocols, so that they can be transmitted through the transmission cable 300.

[0164] By clearly dividing the functions of the pickup panel 100 into an audio acquisition module and a network conversion module, the signal processing flow can be modularized and professionally divided. Specifically, the audio acquisition module is used to pick up audio signals and convert them into digital signals. This process avoids interference that analog signals may encounter during transmission and provides data packets for subsequent digital signal processing. The network conversion module receives the digital signals from the audio acquisition module and converts them into standard network signals for transmission to the first host 200 via the transmission cable 300. This clear division of functions within the pickup panel 100 allows each module to be independently optimized. On the one hand, it simplifies the signal processing path, reducing redundant components and wiring complexity on the circuit board, thereby effectively reducing the overall thickness and internal space occupied by the pickup panel 100, making it easier to achieve an ultra-thin design. On the other hand, the modular design also improves the reliability and consistency of signal conversion, ensuring that the entire process from audio pickup to network transmission is efficient and stable.

[0165] It should be noted that the audio acquisition module in this embodiment may include the aforementioned microphone array and analog-to-digital conversion module. In this example, the microphone array is a collection of sensors used to pick up audio signals. Each microphone array can be composed of multiple independent miniature microphone units arranged in a specific geometric pattern, such as a linear array, circular array, or planar array. The multiple independent microphone units included in the microphone array work together to achieve a wider pickup range, higher sensitivity, and the ability to perceive the direction of the sound source. As another implementation, the microphone array can also be a MEMS (Micro-Electro-Mechanical Systems) microphone array integrated on a single chip to achieve a smaller size and higher integration. The analog-to-digital conversion module included in the audio acquisition module 11a is used to convert the audio signals picked up by the microphone array into digital signals. This analog-to-digital conversion module typically includes one or more analog-to-digital converters (ADCs), which convert continuously varying analog voltage signals into discrete digital bitstreams according to a certain sampling rate and quantization precision. For example, a high-precision Sigma-Delta ADC chip or an ADC function module integrated into an audio codec can be used.

[0166] In this example, the network conversion module includes a processing unit and a physical layer device. The processing unit of the network conversion module packages digital signals into encapsulated frame signals, while the physical layer device of the network conversion module converts the encapsulated frame signals into standard network signals and transmits them to the first host 200 via a transmission cable. The analog-to-digital converter (ADC) is connected between the microphone array and the processing unit, and the processing unit is connected between the ADC and the physical layer device.

[0167] The network conversion module includes a processing unit for receiving the digital signal output from the analog-to-digital conversion module and packaging it into an encapsulated frame signal. Exemplarily, the processing unit in this embodiment can be a system-on-a-chip (SoC), which integrates a processing core, memory, and various peripheral interfaces, enabling data packaging functionality through hardware logic. The physical layer device included in the network conversion module is used to convert the encapsulated frame signal into a standard network signal and transmit it to the first host 200 via a transmission cable. As one feasible implementation, the physical layer device can be an Ethernet physical layer transceiver (PHY chip), responsible for implementing physical layer data encoding, decoding, modulation, demodulation, and media access control. For example, an Ethernet PHY chip conforming to the IEEE 802.3 standard can be used, supporting transmission rates of 100Mbps or 1Gbps.

[0168] The technical solution of this application embodiment refines the audio acquisition module and network conversion module, and clarifies their internal components and connections, constructing an efficient and reliable audio signal processing link. Specifically, the microphone array is responsible for high-fidelity pickup of the original audio signal, ensuring the quality of the input signal. Subsequently, the analog-to-digital conversion module is closely connected to the microphone array, rapidly converting the analog audio signal into a digital signal. This early digitization process effectively avoids the problem of analog signals being susceptible to interference and distortion during transmission, thereby improving signal purity. Next, after receiving the digital signal, the processing device efficiently packages it into encapsulated frame signals. This packaging process can be optimized according to network transmission characteristics to reduce data transmission latency. Finally, the physical layer device converts the encapsulated frame signals into standard network signals and sends them to the first host 200 via transmission cable 300. This standardized network signal transmission method ensures the stability and compatibility of data transmission. In the entire process, the connection between the analog-to-digital conversion module and the microphone array and processing device, as well as the connection between the processing device and the physical layer device, together constitute a seamless signal processing path, minimizing signal loss and latency between each stage. This structured design enables the pickup panel 100 to efficiently and reliably acquire, digitize, package, and transmit audio signals in a network, providing high-quality input signals to the first host 200. This ensures that the entire ceiling microphone system 10 can still achieve excellent real-time performance and stability even under a physically separated architecture.
