It solves the problem that the angle of the microphone needs to be adjusted due to the different heights of individuals in the meeting. Otherwise, after the speaker is replaced, the height will also change. At this time, the distance between the speaker and the microphone will change, which may easily lead to the problem that the sound emitted by the speaker cannot be directly aimed at the microphone. The microphone includes a table, the top of which is provided with grooves that are symmetrical to each other on the left and right; a fixed plate, the upper ends of the left and right ends of the top of the table are fixedly installed with fixed plates, and the middle parts of the two fixed plates are provided with through circular holes; a fixed column, the circular holes in the middle parts of the two fixed plates are respectively inserted with fixed columns, and the annular side walls of the fixed columns are respectively provided with first springs. The angle of the microphone can be adjusted according to the individual's height, so that the head of the microphone is aimed at the person's mouth.

DETAILED DESCRIPTION

[0021] Embodiment 1: See also Figures 1 to 4 The embodiment of the present invention provides an array microphone assembly, which is mainly used to realize the rapid adjustment of multiple microphone bodies 4, and specifically comprises a carrier plate 2, a support assembly 1 for supporting the carrier plate 2, and a plurality of microphone bodies 4. The carrier plate 2 is provided with an adjustment assembly 3 for limiting the position of the microphone bodies 4, and the number of the adjustment assemblies 3 is adapted to the number of the microphone bodies 4. A push rod 5 is slidably mounted on the outer surface of the adjustment assembly 3. When the push rod 5 is pushed into the adjustment assembly 3, the limit between the adjustment assembly 3 and the carrier plate 2 can be released, and then the adjustment assembly 3 and the microphone body 4 can be horizontally moved along the carrier plate 2.

[0022] In the present embodiment, the number of microphone bodies 4 is four, and the adjustment component 3 and the carrier plate 2 are in abutment with each other in the initial state. A T-shaped slot 201 for accommodating the adjustment component 3 is provided on the top surface of the carrier plate 2 along its length direction. The T-shaped slot 201 is inverted so that the adjustment component 3 can be assembled from the left side / rear side, and after assembly, the adjustment component 3 can only slide left and right without falling off.

[0023] Among them, the carrier board 2 is placed on the supporting component 1, and the corresponding adjustment of the height of the carrier board 2 can be achieved through the supporting component 1, thereby achieving the corresponding adjustment of the height of the four microphone bodies 4. When the adjusting component 3 moves left and right along the carrier board 2, the distance between two adjacent microphones can be adjusted.

[0024] Reference Figures 2 to 4 In this embodiment, preferably, the adjustment component 3 includes a handle 301 slidably mounted in the T-slot 201, and correspondingly, the handle 301 is also designed in a T-shape. The interior of the handle 301 is elastically connected to a slider 302 via a first spring 303, and a non-slip layer 306 that abuts against the T-slot 201 is fixedly mounted on the bottom of the slider 302. Under the action of the first spring 303, the slider 302 has a tendency to move downward, so that the non-slip layer 306 can be tightly abutted against the T-slot 201.

[0025] The surface of the slider 302 is provided with a guide groove 305 that fits with the push rod 5; when the push rod 5 moves into the handle 301, the slider 302 can move upward based on the handle 301 through the guide groove 305, so that the slider 302 drives the anti-slip layer 306 to rise and separate from the T-shaped groove 201. In this embodiment, the inclined surface where the push rod 5 and the guide groove 305 fit are both provided with an inclined surface, so as to realize the lifting and lowering of the slider 302, and at the same time, there is a certain distance below the guide groove 305, so that the slider 302 will not interfere with the push rod 5 after rising.

[0026] Furthermore, a clamping seat 304 for clamping the microphone body 4 is rotatably installed on the top of the slider 302 , and a large friction force is set between the clamping seat 304 and the slider 302 , and force needs to be applied to realize the rotation of the clamping seat 304 based on the slider 302 .

[0027] Reference Figure 1 and Figure 2 In this embodiment, preferably: the supporting assembly 1 includes a base 101, the base 101 is used to be placed on the corresponding table top, a central axis 102 sleeved in the carrier plate 2 is fixedly installed on the top of the base 101, and the outer surface of the central axis 102 is threadedly sleeved with a screw sleeve 103 that is against the bottom surface of the carrier plate 2. Rotating the screw sleeve 103 can realize the height adjustment of the screw sleeve 103 based on the central axis 102, so that the carrier plate 2 drives the microphone body 4 to adjust the height.

[0028] When in use, firstly, a plurality of microphone bodies 4 are clamped one by one onto the clamping seat 304, then the carrier plate 2 is sleeved onto the outer surface of the central axis 102, and then the screw sleeve 103 is rotated to adjust the overall height of the carrier plate 2 and the microphone body 4. Then, the grip 301 is held and the push rod 5 is pressed into the grip 301, and the slider 302 is driven to rise through the guide groove 305 and squeeze the first spring 303, thereby separating the anti-slip layer 306 from the T-shaped groove 201. At this time, the grip 301 can be easily slid left and right along the T-shaped groove 201, and the distance between two adjacent microphone bodies 4 can be quickly adjusted.

[0029] To sum up, through the cooperation of structures such as the carrier plate 2, the handle 301, the slider 302 and the push rod 5, the corresponding adjustment of the height of the microphone body 4 can be achieved, and the distance between two adjacent microphone bodies 4 can be quickly adjusted, so that the array microphone formed by the combination can achieve a better sound effect; the overall steps are concise and easy to operate, and can be effectively applied to multiple scenes such as existing meetings and performances. At the same time, when not in use, the carrier plate 2 can be turned downward, and the microphone body 4 can be turned downward, which can effectively reduce dust pollution on the microphone body 4 and in the T-slot 201, and is more practical.

[0030] Embodiment 2: See also Figures 1 to 8On the basis of the first embodiment, considering that the handle 301 can only slide left and right along the T-slot 201, the microphone body 4 is mostly oriented toward the front. After the array microphone is combined, the microphone body 4 on both sides of the edge cannot effectively correspond to the user, and thus the sound effect still needs to be improved.

[0031] For this purpose, the handle 301 is improved: the lower side of the handle 301 is opened into a frustum 307, so that the handle 301 can be normally assembled from the T-slot 201 and can also rotate based on the T-slot 201, thereby adjusting the corresponding angle between the microphone body 4 and the user.

[0032] Furthermore, a cross bar 502 extending into the guide groove 305 is slidably installed on the side of the handle 301 away from the push rod 5, and a semicircular plate 501 is fixedly installed on the opposite end of the cross bar 502 and the push rod 5. The combination of the two semicircular plates 501 forms a complete circle, and a rack 503 is fixedly installed on the opposite side of the cross bar 502 and the push rod 5. A gear 504 that is transmission-connected to the two racks 503 is fixedly installed on the inner wall of the handle 301.

[0033] The two racks 503 are symmetrically arranged based on the gear 504, so that the push rod 5 and the cross bar 502 have the same movement process, so that when the push rod 5 is misplaced, the push rod 5 can still be quickly moved relative to the handle 301. At the same time, the spacing between the two semicircular plates 501 and the outer surface of the handle 301 is equal, so that at this time, there is no need to hold the handle 301, but only the two semicircular plates 501 need to be held.

[0034] In the above structure, 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.

[0035] When in use, the height adjustment of the microphone body 4 and the distance adjustment between two adjacent microphone bodies 4 can be achieved through the structures such as the carrier plate 2, the handle 301 and the push rod 5. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that the two semicircular plates 501 can be held to separate the anti-slip layer 306 from the T-shaped groove 201, so that the handle 301 can move along the T-shaped groove 201. At the same time, when holding the two semicircular plates 501, the handle 301 can also be rotated to adjust the direction of the microphone body 4, so that the two microphone bodies 4 can also be effectively matched by the user.

[0036] Compared with the first embodiment, through the cooperation of the structures such as the handle 301, the round table 307, the push rod 5 and the semicircular plate 501, on the basis of the height adjustment and spacing adjustment of the microphone body 4, the orientation angle of the microphone body 4 can also be quickly adjusted to form an effective correspondence with the user, thereby further ensuring the sound effect; and the spacing adjustment and angle adjustment of the microphone body 4 adopt the same set of structures, which can ensure the simplicity of the overall structure. The overall solution is combined with the setting of the handle 301. When the handle 301 rotates based on the T-slot 201, the position of the push rod 5 can still be quickly adjusted by holding the two semicircular plates 501, which is not affected by the misalignment of the push rod 5 after rotation, and has stronger applicability.

[0037] Embodiment three: See also Figures 1 to 10 On the basis of the second embodiment, considering that the carrier plate 2 is sleeved outside the central axis 102 and achieves height support, its left and right directions are not limited, so that the carrier plate 2 may rotate left and right during the adjustment of the handle 301, affecting the overall sound effect of the array microphone.

[0038] To this end, the screw sleeve 103 is improved: at this time, a U-shaped block 104 that is rotatably mounted on the outer surface of the screw sleeve 103 and movably fits with the top surface of the carrier plate 2, the U-shaped block 104 is arranged sideways and its lower end is used to rotatably fit with the outer surface of the screw sleeve 103, and the bottom surface of its upper end can fit with the top surface of the carrier plate 2; when the U-shaped block 104 is in fit with the carrier plate 2, effective positioning of the carrier plate 2 can be achieved.

[0039] Reference Fig. 9 and Fig.10 In this embodiment, preferably: the outer surface of the screw sleeve 103 is elastically connected with a block 107 that movably engages with the U-shaped block 104 through a second spring 106, and the inner wall of the U-shaped block 104 is provided with a slot 105 that is adapted to the block 107. When the second spring 106 makes the block 107 extend from the outer surface of the screw sleeve 103, it can engage with the slot 105 so that the U-shaped block 104 will not rotate easily, but force needs to be applied to make the U-shaped block 104 rotate relative to the screw sleeve 103.

[0040] Furthermore, the U-shaped block 104 is configured to be telescopic up and down and is elastically connected through a third spring (not shown in the figure), so that the upper and lower ends of the side U-shaped block 104 can move relatively, and the third spring makes the upper and lower ends tend to approach each other, thereby making the U-shaped block 104 suitable for carrier plates 2 of different thicknesses.

[0041] When in use, the height adjustment of the microphone body 4 and the spacing adjustment between two adjacent microphone bodies 4 can be achieved through the structures such as 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 structures such as the handle 301, the round table 307 and the semicircular plate 501, so that it can form an effective correspondence with the user. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is that after the carrier plate 2 is engaged in the U-shaped block 104, the screw sleeve 103 is sleeved outside the central axis 102, and then the screw sleeve 103 is rotated based on the central axis 102 to drive the U-shaped block 104 to descend, so that the carrier plate 2 is correspondingly descended.

[0042] Compared with the second embodiment, the limited position of the carrier plate 2 in the left and right directions can be achieved through the cooperation of the screw sleeve 103, the U-shaped block 104, the clamping block 107 and the second spring 106, so as to avoid the influence of the displacement of the carrier plate 2 during the movement of the handle 301 in the later stage, and ensure the overall stability of the adjustment of the microphone body 4. The overall solution is combined with the setting of the screw sleeve 103, so that the carrier plate 2 will not deviate up and down, and the influence of the rotation of the carrier plate 2 can be avoided, meeting more requirements in actual use.

[0043] Embodiment 4: See also Figures 1 to 10 An embodiment of the present invention provides an assembly method of an array microphone assembly. This embodiment adopts any one of embodiments one to three, and therefore also has corresponding beneficial effects.
