Description

Technical Field

[0001] This invention relates to the field of array microphone technology, and in particular to an array microphone assembly and its assembly method. Background Technology

[0002] Multiple microphones can be arranged into an array microphone to accurately capture the voices of different participants and suppress noise from other directions, thereby improving the clarity of speech and communication in a meeting. In broadcasting and presentation scenarios, array microphones can accurately capture the speaker's voice while suppressing noise from other directions.

[0003] For example, Chinese Patent Publication No. CN216057410U discloses a conference microphone array that can be fixed to a tabletop, relating to the field of broadcasting technology. This invention addresses the problem of existing conference microphones where the microphone angle needs adjustment due to varying heights of participants. Otherwise, changes in speaker height alter the distance between the speaker and the microphone, potentially causing the speaker's voice to be out of direct contact with the microphone. The invention includes a tabletop with symmetrical grooves at its top; mounting plates fixed to the top of both sides of the tabletop, each with a through-hole in its center; and mounting posts inserted into the holes in the two mounting plates, each with a first spring fitted onto its annular sidewall. This design allows for microphone angle adjustment based on individual height, ensuring the microphone head is aligned with the speaker's mouth.

[0004] The microphones in this application are in a relatively fixed state, and the resulting array microphone has a fixed sound output effect, which cannot be effectively applied to different scenarios and has certain limitations in use.

[0005] Therefore, it is necessary to provide an array microphone assembly and its assembly method to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an array microphone assembly and its assembly method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, an array microphone assembly with adjustable microphone body height and adjustable spacing between adjacent microphone bodies and its assembly method are designed.

[0008] Based on the above ideas, the present invention provides the following technical solution: an array microphone assembly and its assembly method, comprising a plurality of microphone bodies, and further comprising a carrier plate and a support assembly for supporting the carrier plate, wherein an adjustment assembly for limiting the microphone bodies is provided on the carrier plate, and a push rod is slidably mounted on the outer surface of the adjustment assembly; when the push rod is pushed toward the adjustment assembly, the limiting between the adjustment assembly and the carrier plate is released.

[0009] As a further aspect of the present invention: the top surface of the carrier plate is provided with a T-shaped groove along its length for accommodating a plurality of adjustment components, and the T-shaped groove is designed to be inverted.

[0010] As a further aspect of the present invention: the adjustment component includes a handle slidably installed in a T-groove, a slider elastically connected inside the handle by a first spring, and an anti-slip layer fixedly installed at the bottom of the slider against the T-groove; the first spring causes the slider to have a downward tendency, thereby causing the anti-slip layer to abut against the T-groove.

[0011] As a further aspect of the present invention: the surface of the slider is provided with a guide groove that fits with the push rod, and the bottom surface of the guide groove is spaced apart from the bottom surface of the push rod; when the push rod moves into the grip, it passes through the guide groove to realize the slider rising based on the grip.

[0012] As a further aspect of the present invention: a clamp for holding the microphone body is rotatably mounted on the top of the slider.

[0013] As a further aspect of the present invention: the support assembly includes a base, and a central shaft sleeved in the carrier plate is fixedly installed on the top of the base. The outer surface of the central shaft is threaded with a threaded sleeve that abuts against the bottom surface of the carrier plate.

[0014] As a further aspect of the present invention: a frustum is provided on the lower side of the grip, and the grip can both translate along the T-slot and rotate on its own based on the T-slot.

[0015] As a further embodiment of the present invention: a crossbar extending into the guide groove is slidably mounted on the outer surface of the grip, and a semicircular plate is fixedly mounted on the opposite end of the crossbar and the push rod. The two semicircular plates are combined to form a complete circle. A rack is fixedly mounted on the opposite side of the crossbar and the push rod, and a gear that is pultrusively connected to both racks is fixedly mounted on the inner wall of the grip.

[0016] As a further aspect of the present invention: the two racks are arranged symmetrically and alternately based on gears, so that the push rod and the crossbar have the same movement process, and the distance between the two semicircular plates and the outer surface of the handle is designed to be equal.

[0017] The present invention also provides the following technical solution: an assembly method for an array microphone assembly, which adopts any of the above technical solutions. First, a carrier plate is mounted on a support assembly and the height of the carrier plate is adjusted. Then, several microphone bodies are mounted on an adjustment assembly, and the adjustment assemblies are mounted on the carrier plate one by one. Then, a push rod is pressed towards the adjustment assembly to release the limiting between the adjustment assembly and the carrier plate. Finally, the adjustment assembly is moved along the carrier plate to adjust the spacing between two adjacent microphone bodies.

[0018] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the carrier plate, adjustment component, support component and push rod, the height of the microphone body can be adjusted accordingly, and the spacing between two adjacent microphone bodies can be quickly adjusted, thereby enabling the array microphone formed by the combination to achieve better sound output; the overall steps are simple and convenient to operate, and it can be effectively applied to multiple scenarios such as existing meetings and performances. At the same time, when not in use, the carrier plate can be placed downwards, and the microphone body can be placed downwards, which can effectively reduce dust pollution on the microphone body, making it more practical.

[0031] Example 1:

[0032] Please see Figures 1 to 4 This invention provides an array microphone assembly, primarily used for rapid adjustment of multiple microphone bodies 4. Specifically, it includes a carrier plate 2, a support component 1 for supporting the carrier plate 2, and several microphone bodies 4. The carrier plate 2 is provided with adjustment components 3 for limiting the position of the microphone bodies 4, and the number of adjustment components 3 is adapted to the number of microphone bodies 4. A push rod 5 is slidably mounted on the outer surface of the adjustment component 3. When the push rod 5 is pushed into the adjustment component 3, the limiting relationship between the adjustment component 3 and the carrier plate 2 is released, allowing the adjustment component 3 and the microphone bodies 4 to move horizontally along the carrier plate 2.

[0033] In this embodiment, there are four microphone bodies 4, and the adjustment component 3 and the carrier plate 2 are in abutting state in the initial state. The top surface of the carrier plate 2 is provided with a T-shaped groove 201 for placing the adjustment component 3 along its length direction. The T-shaped groove 201 is inverted, so that the adjustment component 3 can be assembled from the left / rear side, and after assembly, the adjustment component 3 can only slide left and right without falling off.

[0034] The carrier plate 2 is placed on the support component 1. The height of the carrier plate 2 can be adjusted accordingly through the support component 1, thereby adjusting the height of the four microphone bodies 4. When the adjustment component 3 moves left and right along the carrier plate 2, the spacing between two adjacent microphones can be adjusted.

[0035] Reference Figures 2 to 4 In this embodiment, preferably, the adjustment component 3 includes a handle 301 slidably installed in the T-shaped groove 201, and correspondingly, the handle 301 is also T-shaped. A slider 302 is elastically connected inside the handle 301 via a first spring 303. An anti-slip layer 306 is fixedly installed at the bottom of the slider 302, abutting against the T-shaped groove 201. Under the action of the first spring 303, the slider 302 tends to move downwards, thereby allowing the anti-slip layer 306 to tightly abut against the T-shaped groove 201.

[0036] The slider 302 has a guide groove 305 on its surface that fits into the push rod 5. When the push rod 5 moves into the grip 301, the slider 302 moves upward based on the grip 301 through the guide groove 305, thereby causing the slider 302 to lift the anti-slip layer 306 and separate it from the T-shaped groove 201. In this embodiment, the inclined surfaces where the push rod 5 and the guide groove 305 fit together are both inclined to achieve the lifting and lowering of the slider 302. At the same time, there is a certain gap below the guide groove 305 so that the slider 302 will not interfere with the push rod 5 after it rises.

[0037] Furthermore, a clamp 304 for holding the microphone body 4 is rotatably mounted on the top of the slider 302. There is a large friction between the clamp 304 and the slider 302, and force needs to be applied to make the clamp 304 rotate based on the slider 302.

[0038] Reference Figure 1 and Figure 2 In this embodiment, preferably, the support component 1 includes a base 101, which is used to place on a corresponding table. A central shaft 102 is fixedly installed on the top of the base 101 and sleeved in the carrier plate 2. A threaded sleeve 103 is threaded on the outer surface of the central shaft 102 and abuts against the bottom surface of the carrier plate 2. Rotating the threaded sleeve 103 can realize the height adjustment of the threaded sleeve 103 based on the central shaft 102, thereby causing the carrier plate 2 to drive the microphone body 4 to adjust its height.

[0039] In use, first clamp several microphone bodies 4 one by one onto the clamp 304, then place the carrier plate 2 onto the outer surface of the central shaft 102, and then rotate the screw sleeve 103 to adjust the overall height of the carrier plate 2 and the microphone body 4. Next, hold the handle 301 and press the push rod 5 into the handle 301. The guide groove 305 drives the slider 302 to rise and squeeze the first spring 303, thereby separating the anti-slip layer 306 from the T-shaped groove 201. At this time, the handle 301 can be easily slid left and right along the T-shaped groove 201, thereby quickly adjusting the distance between two adjacent microphone bodies 4.

[0040] In summary, through the cooperation of the carrier plate 2, handle 301, slider 302, and push rod 5, the height of the microphone body 4 can be adjusted accordingly, and the spacing between two adjacent microphone bodies 4 can be quickly adjusted, thereby enabling the array microphone to achieve better sound output. The overall steps are simple and convenient to operate, and it can be effectively applied to various scenarios such as meetings and performances. At the same time, when not in use, the carrier plate 2 can be placed downwards, and the microphone body 4 can be placed downwards, which can effectively reduce dust accumulation on the microphone body 4 and in the T-shaped groove 201, making it more practical.

[0041] Example 2:

[0042] Please see Figures 1 to 8 Based on Embodiment 1, considering that the grip 301 can only slide left and right along the T-shaped groove 201, the microphone body 4 is mostly oriented towards the front. After combining the array microphones, the microphone bodies 4 on both sides cannot effectively correspond to the user, thus the sound output effect still needs to be improved.

[0043] Therefore, the grip 301 is improved: the lower side of the grip 301 is formed into a frustum 307, so that the grip 301 can be normally assembled from the T-slot 201, and can also rotate on its own based on the T-slot 201, thereby adjusting the corresponding angle between the microphone body 4 and the user.

[0044] Furthermore, a crossbar 502 extending into the guide groove 305 is slidably installed on the side of the grip 301 away from the push rod 5. A semi-circular plate 501 is fixedly installed on the opposite end of the crossbar 502 and the push rod 5. The two semi-circular plates 501 are combined to form a complete circle. A rack 503 is fixedly installed on the opposite side of the crossbar 502 and the push rod 5. A gear 504 that is drively connected to both racks 503 is fixedly installed on the inner wall of the grip 301.

[0045] The two racks 503 are arranged symmetrically and alternately based on the gears 504, so that the push rod 5 and the crossbar 502 have the same movement process. This allows the push rod 5 to move quickly relative to the handle 301 even when it is misaligned. At the same time, the distance between the two semicircular plates 501 and the outer surface of the handle 301 is equal, so that it is not necessary to hold the handle 301 anymore, but only to hold the two semicircular plates 501.

[0046] In the above structure, the opening of the guide groove 305 is not only suitable for avoiding the push rod 5, but also ensures that the slider 302 will not interfere with the gear 504 after rising along the handle 301.

[0047] In use, the height of the microphone body 4 and the spacing between two adjacent microphone bodies 4 can be adjusted through the structure of the carrier plate 2, the grip 301, and the push rod 5. The working process and effect of this part are the same as in Embodiment 1, and will not be repeated here. The difference is that the two semicircular plates 501 can be gripped to separate the anti-slip layer 306 from the T-shaped groove 201, thereby allowing the grip 301 to move along the T-shaped groove 201. At the same time, when gripping the two semicircular plates 501, the grip 301 can also be rotated to adjust the orientation of the microphone body 4, so that the two microphone bodies 4 can be effectively aligned by the user.

[0048] Compared to Embodiment 1, the combination of the grip 301, frustum 307, push rod 5, and semicircular plate 501 allows for rapid adjustment of the microphone body 4's orientation angle, in addition to height and spacing adjustments, ensuring effective alignment with the user and further guaranteeing sound quality. Furthermore, the spacing and angle adjustments of the microphone body 4 utilize the same structure, maintaining overall structural simplicity. The integrated design with the grip 301 allows for rapid adjustment of the push rod 5's position even after the grip 301 rotates based on the T-slot 201, without being affected by misalignment of the push rod 5 after rotation, thus enhancing its versatility.

[0049] Example 3:

[0050] Please see Figures 1 to 10 Based on Embodiment 2, considering that although the carrier plate 2 is fitted outside the central axis 102 and achieves height support, its left and right directions are not limited, the carrier plate 2 may rotate left and right during the adjustment of the grip 301, affecting the overall sound output effect of the array microphone.

[0051] Therefore, the screw sleeve 103 is improved: a U-shaped block 104 is rotatably mounted on the outer surface of the screw sleeve 103 and movably fits against the top surface of the carrier plate 2. The U-shaped block 104 is arranged in a side manner, with its lower end used to rotatably fit against the outer surface of the screw sleeve 103, and its upper bottom surface can fit against the top surface of the carrier plate 2. When the U-shaped block 104 fits against the carrier plate 2, it can effectively limit the movement of the carrier plate 2.

[0052] Reference Figure 9 and Figure 10 In this embodiment, preferably, the outer surface of the threaded sleeve 103 is elastically connected to a locking block 107 that engages with the U-shaped block 104 via a second spring 106. The inner wall of the U-shaped block 104 is provided with a locking groove 105 that matches the locking block 107. When the second spring 106 causes the locking block 107 to extend from the outer surface of the threaded sleeve 103, it can engage with the locking groove 105 so that the U-shaped block 104 will not rotate easily, but requires force to rotate relative to the threaded sleeve 103.

[0053] Furthermore, the U-shaped block 104 is configured to be telescopic and elastically connected by a third spring (not shown in the figure), so that the upper and lower ends of the side-type U-shaped block 104 can move relative to each other, and the third spring makes the upper and lower ends tend to move closer to each other, thereby making the U-shaped block 104 applicable to carrier plates 2 of different thicknesses.

[0054] In use, the height of the microphone body 4 and the spacing between adjacent microphone bodies 4 can be adjusted through the structure of the carrier plate 2, the handle 301, and the push rod 5. The orientation angle of the microphone body 4 can also be quickly adjusted through the structure of the handle 301, the frustum 307, and the semi-circular plate 501, ensuring effective alignment with the user. The working process and effect of this part are the same as in Embodiment 2, and will not be repeated here. The difference lies in that: after the carrier plate 2 is engaged within the U-shaped block 104, the screw sleeve 103 is fitted onto the outside of the central shaft 102. Then, based on the central shaft 102, the screw sleeve 103 is rotated, causing the U-shaped block 104 to descend, thus causing the carrier plate 2 to descend accordingly.

[0055] Compared to Embodiment 2, the combination of the screw sleeve 103, U-shaped block 104, locking block 107, and second spring 106 allows for limited left-right positioning of the carrier plate 2, preventing offset of the carrier plate 2 during later movement of the grip 301 and ensuring the overall stability of the microphone body 4 adjustment. The overall solution, combined with the screw sleeve 103, prevents the carrier plate 2 from shifting vertically and avoids the effects of rotation, thus meeting more practical needs.

[0056] Example 4:

[0057] Please see Figures 1 to 10 This invention provides a method for assembling an array microphone assembly. This embodiment adopts any one of the embodiments one to three, and therefore also has corresponding beneficial effects.

[0058] Specifically, first, the carrier plate 2 is mounted on the support assembly 1 and the height of the carrier plate 2 is adjusted. Then, several microphone bodies 4 are mounted on the adjustment assembly 3, and the adjustment assembly 3 is mounted on the carrier plate 2 one by one. Then, the push rod 5 is pressed in the direction of the adjustment assembly 3 to move the adjustment assembly 3 left and right along the carrier plate 2, thereby adjusting the distance between two adjacent microphone bodies 4.
