Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
As shown in Figures 1 to 4, adjustable microphone array arrangement apparatus, including support frame 1 and it is fixedly installed on support frame
The rectangle framework at 1 top, the rectangle framework two side is to be respectively provided between chute, and two slide bars in slide bar, and slide bar
Horizontally disposed guide rod group, the guide rod group includes some guide rods 4 arranged in parallel up and down, and the guide rod 4 is slided with slide bar 3 and connected
Connect, draw-in groove 5 is set on any guide rod 4, the draw-in groove is two-sided slot structure.
Further, the top of support frame as described above 1 sets fixing groove 2, and the fixing groove 2 is U-shape structure, the U-shape structure with
Rectangle framework bottom width matches, and U-type groove side sets the bottom bolts of circular hole, the fixing groove and rectangle framework
Connection.
Further, the top of support frame as described above 1 sets retractor device.By setting retractor device, realize that rectangle framework exists
Vertical direction is moved, and then adjusts the height of draw-in groove 5.
Further, the surface of the guide rod 4 sets scale.By setting scale, draw-in groove 5 can be moved to fixed position by user
Put.
Further, the inside of the slide bar 3 sets slideway, and guide rod 4 can be slided on slideway.
It is described to be raised in slideway engaging it is further preferred that one end of the guide rod 4 sets raised, the guide rod 4 it is another
The outer wall of one end sets external screw thread, and the outer wall of the slide bar 3 sets nut, and nut internal diameter matches with the diameter of guide rod 4.Pass through
Adjusting nut is to be capable of achieving guide rod 4 in the enterprising line slip of slideway.
It is further preferred that the outer surface of the slide bar 3 sets scale, and scale value initial value is arranged at slide bar bottom.Pass through
Scale is set, and guide rod 4 is moved to user the position of needs according to scale, and position precision is high.
