Specific embodiment
Present invention will be further explained below with reference to the attached 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 sidewalls are slide bar, and sliding slot are respectively provided in slide bar, and between two slide bars
Horizontally disposed guide rod group, the guide rod group include guide rod 4 arranged in parallel above and below several, and the guide rod 4 connects with the sliding of slide bar 3
It connects, card slot 5 is set on any guide rod 4, the card slot is two-sided slot structure.
Further, at the top of support frame as described above 1 be arranged fixing groove 2, the fixing groove 2 be U-shaped structure, the U-shaped structure with
Rectangle framework bottom width matches, and circular hole, the bottom bolts of the fixing groove and rectangle framework are arranged in U-type groove side
Connection.
Further, telescopic device is set at the top of support frame as described above 1.By the way that telescopic device is arranged, realize that rectangle framework exists
Vertical direction is moved, and then adjusts the height of card slot 5.
Further, scale is arranged in 4 surface of guide rod.By the way that scale is arranged, card slot 5 can be moved to fixed position by user
It sets.
Further, slideway is set inside the slide bar 3, guide rod 4 can slide on slideway.
It is further preferred that the guide rod 4 one end be arranged protrusion, it is described be raised in slideway engaging, the guide rod 4 it is another
External screw thread is arranged in the outer wall of one end, and nut is arranged in 3 outer wall of slide bar, and nut internal diameter and the diameter of guide rod 4 match.Pass through
