Problems solved by technology

[0002] At present, a microphone array refers to an array formed by a plurality of microphones arranged in different shapes. The existing microphone array arrangement device only arranges several microphones at fixed positions, and the array structure formed by the microphones is relatively simple. The shape is less, because the existing microphone array arrangement device is not equipped with special components for adjusting the height and horizontal position of the microphone, it is difficult to meet the randomness and diversity requirements of the user for the arrangement of the microphone array, that is, it is impossible to arrange the microphones flexibly and diversely , which makes the error of the experimental results larger, making the directivity analysis results of the sound source array inaccurate

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0025] Such as Figure 1 to Figure 4 As shown, the adjustable microphone array arrangement device includes a support frame 1 and a rectangular frame fixedly arranged on the top of the support frame 1. A guide rod group is arranged horizontally between the slide rods, the guide rod group includes several guide rods 4 arranged in parallel up and down, the guide rods 4 are slidably connected with the slide rod 3, and any one of the guide rods 4 is provided with a card slot 5, The card slot is a double-sided slot structure.

[0026] Further, the top of the support frame 1 is provided with a fixing groove 2, the fixing groove 2 is a U-shaped structure, the U-shaped structure matches the width of the bottom of the rectangular frame, and a round hole is arranged on the side of the U-shaped groove, and the fixing groove Bolt connection with the bottom of the rectangular...

Abstract

The invention discloses an adjustable microphone array arrangement device, which comprises a support frame and a rectangular frame body fixedly arranged at the top of the support frame, wherein slide bars are arranged at two side walls of the rectangular frame; sliding chutes are arranged in the slide bars; a guide rod group is arranged between the two slide bars and comprises a plurality of guide rods which are arranged up and down in parallel; the guide rods are connected with the slide bars in a sliding manner; clamping groovesare arranged in the guide rods; and each clamping groove is of a double groove structure. Diverse flexible arrangement is provided for microphones, the condition that the microphones are arranged into higher-accuracy diverse arrays becomes possible, and the error of experiment results can be greatly reduced, so that analysis of the sound source array directivity is improved.

Description

technical field [0001] The invention relates to the technical field of sound source collection, in particular to an adjustable microphone array arrangement device. Background technique [0002] At present, a microphone array refers to an array formed by a plurality of microphones arranged in different shapes. The existing microphone array arrangement device only arranges several microphones at fixed positions, and the array structure formed by the microphones is relatively simple. The shape is less, because the existing microphone array arrangement device is not equipped with special components for adjusting the height and horizontal position of the microphone, it is difficult to meet the randomness and diversity requirements of the user for the arrangement of the microphone array, that is, it is impossible to arrange the microphones flexibly and diversely , so that the error of the experimental results is large, making the directivity analysis results of the sound source ar...
