[0002] With the rapid development of digital broadcasting technology, optimizing the shock resistance and noise reduction performance of microphone support devices has become an important research direction for improving broadcast sound quality. However, existing microphone support devices still have certain shortcomings in structural design and functional implementation, especially in terms of shock resistance and noise reduction effects in complex environments, making it difficult to meet the needs of high-precision broadcasting.

[0003] A search revealed a microphone stand in Chinese patent publication number CN112738675B, published on May 14, 2024. This patent provides an adjustable-angle and adjustable-support microphone stand, including a tabletop clamp, a multi-segment arm, and a microphone base, capable of accommodating microphones of varying weights and flexibly adjusting the support angle. However, the shock absorption design of this solution is relatively weak, relying solely on hollow profiles and a simple connection structure, resulting in limited effectiveness in absorbing external vibrations. Furthermore, the stand lacks integrated active noise cancellation, offering insufficient protection against environmental noise and limiting its application in demanding broadcasting scenarios.

[0020] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] This invention provides a shockproof and noise-reducing digital broadcast microphone support device, the specific implementation of which is described in detail with reference to the accompanying drawings. Figures 6 to 8 As shown, the device includes a support assembly and a connecting assembly, wherein the support assembly consists of a support platform 1, a first adjusting arm 2, a second adjusting arm 3, a third adjusting arm 4, and a support leg 5, as shown. Figures 1 to 5 As shown, the connecting assembly includes an annular fixing member 7, a piezoelectric actuator 8, a control unit 9, a support column 10, a limiting block 11, a buffer connector 12, and a mounting base 13. The connection relationships, positional relationships, and mutual cooperation relationships between the components will be described one by one in the following sections.

[0022] like Figure 6 As shown, the support platform 1 is located at the center of the support assembly, and it has a receiving groove for fixing with the support column 10. The outer wall of the support column 10 has multiple protrusions, while the inner wall of the receiving groove has grooves corresponding to the protrusions. The cooperation between the protrusions and grooves achieves a tight connection between the support column 10 and the support platform 1. This design not only ensures the stability of the support column 10 within the receiving groove, but also facilitates quick assembly and disassembly. The inner wall of the receiving groove has a buffer layer 15, which is made of a high-polymer elastic material and is fixed to the receiving groove by adhesive. The design of the buffer layer 15 can absorb the influence of external vibrations on the support platform 1, while avoiding stress concentration problems caused by rigid contact.

[0023] Three first adjusting arms 2 are evenly distributed around the perimeter of the support platform 1. The first adjusting arms 2 are connected to the support platform 1 by hinges. A second adjusting arm 3 is hinged to the other end of each first adjusting arm 2. A third adjusting arm 4 is hinged to the second adjusting arm 3. A support leg 5 is threaded onto the third adjusting arm 4. Figure 7 As shown, the multi-stage adjustment structure of the first adjusting arm 2, the second adjusting arm 3, and the third adjusting arm 4 allows the support leg 5 to be adjusted at different heights and angles, thus adapting to the needs of complex terrain. A piezoelectric sensing element 6 is embedded inside the bottom surface of the support leg 5. The piezoelectric sensing element 6 is fixed by an embedded mounting method and connected to the control unit 9 via a wire. Figure 2 As shown, the bottom of the support leg 5 is also provided with at least one suction cup 7. The design of the suction cup 7 enhances the adhesion between the support leg 5 and the ground, further improving the overall stability of the device.

[0024] like Figure 4 and Figure 5 As shown, the annular fastener 7 in the connecting assembly has a hollow structure with reinforcing ribs on its inner wall. These ribs are evenly distributed along the inner wall of the annular fastener 7 and have a trapezoidal cross-section, with the wider side of the trapezoid facing the center of the annular fastener 7. This reinforcing rib design effectively disperses external stress and improves the overall rigidity of the annular fastener 7. A damping ring 14 is installed inside the annular fastener 7. The damping ring 14 is fixed by a snap-fit ​​mechanism and is made of multi-layer composite material, with a high-damping rubber inner layer and a high-strength fiber material outer layer. This multi-layer composite material design ensures damping performance while improving the overall structural strength. A control unit 9 is located on the side wall of the annular fastener 7. The control unit 9 is electrically connected to the piezoelectric detection element 6 and the piezoelectric actuator 8, respectively. The control unit 9 includes a signal processing module and a drive control module. The signal processing module receives the signal from the piezoelectric sensing element 6, performs filtering and amplification processing, and transmits it to the drive control module. The drive control module adopts an adaptive fuzzy PID control algorithm, calculates and generates a drive command that is opposite in phase and matches the amplitude of the external vibration in real time based on the processed signal, so as to generate reverse vibration through the piezoelectric actuator 8, thereby effectively canceling the influence of the external vibration.

[0025] A support column 10 is rotatably connected to the bottom of the annular fastener 7. The support column 10 is detachably inserted into the receiving groove of the support platform 1 and fixed in place with the receiving groove. A limiting block 11 is provided at the center of the annular fastener 7, and a buffer connector 12 is rotatably connected to the limiting block 11. Figure 4 As shown, the outer wall of the buffer connector 12 has multiple annular grooves, and rubber rings 17 are embedded in the annular grooves. The design of the rubber rings 17 further enhances the shock absorption performance of the buffer connector 12, while avoiding wear problems caused by long-term use. A mounting base 13 is installed on the upper part of the buffer connector 12 via a threaded connection. The inner wall of the mounting base 13 has multiple positioning holes, and magnetic elements 18 are embedded in the positioning holes. Figure 1 and Figure 4 As shown, the design of the magnetic element 18 enhances the connection stability between the mounting base 13 and the microphone, while also facilitating quick assembly and disassembly.

[0026] During actual operation, when external vibrations act on the device, the piezoelectric sensing element 6 on the bottom surface of the support leg 5 monitors the vibration in real time and transmits the signal to the control unit 9. The signal processing module of the control unit 9 filters and amplifies the received signal, and the drive control module generates a drive command based on the processed signal and sends it to the piezoelectric actuator 8. The piezoelectric actuator 8 generates reverse vibration according to the drive command to counteract the influence of external vibrations, thereby achieving active vibration damping. Simultaneously, the design of the buffer layer 15, the damping ring 14, and the rubber ring 17 further enhances the device's vibration damping performance, ensuring the stability of the overall structure. Furthermore, the suction cup 7 enhances the adhesion between the support leg 5 and the ground, while the magnetic element 18 facilitates quick assembly and disassembly of the microphone, and the protrusion and groove design ensures a tight connection between the support column 10 and the receiving groove.

[0027] In specific applications, such as digital broadcasting, this device can effectively cope with vibration interference in complex environments, ensuring high-quality audio signals acquired by the microphone. Through the above-mentioned technical means, this invention achieves active vibration reduction and noise reduction functions, while possessing good adaptability to complex environments, meeting the needs of the digital broadcasting field for high-quality audio acquisition equipment.

[0028] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention is further explained below in conjunction with a specific application scenario.

[0029] In digital broadcasting scenarios, microphone support devices need to cope with vibration interference and noise issues in complex environments. Firstly, when the device is placed on the ground, the suction cups 7 at the bottom of the support legs 5 create a vacuum by contacting the ground, thereby enhancing the overall stability of the device. The design of the suction cups 7 effectively prevents device displacement caused by external vibrations, while also providing basic support for subsequent shock absorption functions. Simultaneously, the piezoelectric sensing element 6 embedded in the bottom surface of the support legs 5 begins to monitor external vibration signals in real time and transmits the collected vibration data to the control unit 9 via wires.

[0030] When external vibrations act on the device, the signal processing module in control unit 9 filters and amplifies the received vibration signal to remove noise interference and extract valid vibration information. Subsequently, the drive control module generates a drive command based on the processed signal and sends it to the piezoelectric actuator 8. Upon receiving the drive command, the piezoelectric actuator 8 generates a reverse vibration opposite to the direction of the external vibration, thereby counteracting the impact of the external vibration on the device. This process achieves active vibration damping, ensuring that the microphone maintains stable operation even in complex environments.

[0031] During the damping process, the buffer layer 15, the damping ring 14, and the rubber ring 17 work together. For example... Figure 6As shown, the buffer layer 15 on the inner wall of the receiving groove is made of a high-polymer elastic material, which can absorb the energy transmitted from external vibrations to the bearing platform 1, avoiding stress concentration problems caused by rigid contact. The damping ring 14 inside the annular fastener 7 is designed with multi-layer composite materials. Its inner high-damping rubber can effectively absorb vibration energy, while the outer high-strength fiber material improves the overall structural strength. In addition, as Figure 5 As shown, the rubber ring 17 embedded in the outer wall of the buffer connector 12 further enhances the shock absorption performance and reduces wear problems that may occur during long-term use.

[0032] In practical operation, when it is necessary to adjust the height or angle of the device to adapt to different terrains, flexible adjustment can be achieved through the multi-stage adjustment structure of the first adjusting arm 2, the second adjusting arm 3, and the third adjusting arm 4. For example... Figure 2 As shown, the first adjusting arm 2 is hinged to the support platform 1, the second adjusting arm 3 is also hinged to the first adjusting arm 2, and the third adjusting arm 4 is fitted with a support leg 5 via a threaded connection. This multi-stage adjustment structure allows the support leg 5 to be precisely adjusted at different heights and angles, thus meeting the needs of complex terrain.

[0033] When the microphone is mounted on the device, the magnetic element 18 embedded in the inner wall of the mounting base 13 enhances the connection stability between the microphone and the magnetic element through magnetic attraction. For example... Figure 4 As shown, the design of the magnetic element 18 not only facilitates quick assembly and disassembly of the microphone, but also ensures that the microphone will not loosen due to vibration during operation. In addition, the support column 10 is inserted into the receiving groove of the support platform 1 through the cooperation of the protrusion and the groove, ensuring a tight connection between the support column 10 and the support platform 1. This design ensures both structural stability and facilitates quick assembly and disassembly.

[0034] During the aforementioned operation, the synergistic effect of each component ensures the high performance of the device in complex environments. For example, in the field of digital broadcasting, when the external vibration frequency is high, the piezoelectric detection element 6 can quickly capture the vibration signal and transmit it to the control unit 9. The control unit 9, through the synergistic effect of the signal processing module and the drive control module, quickly generates a drive command and sends it to the piezoelectric actuator 8. The reverse vibration generated by the piezoelectric actuator 8 cancels out the external vibration, thereby achieving active vibration damping. At the same time, the design of the buffer layer 15, the damping ring 14, and the rubber ring 17 further enhances the device's vibration damping performance, ensuring high-quality audio signals acquired by the microphone.

[0035] By combining the above steps and principles, this invention can effectively cope with vibration interference in complex environments in the field of digital broadcasting, ensuring high-quality audio signals acquired by the microphone. The device's active vibration damping and noise reduction functions, as well as its excellent adaptability to complex environments, meet the demands of the digital broadcasting field for high-quality audio acquisition equipment.
