Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

To shown in Figure 5, figure grade is described as follows: base body 1, fixed lever 11, the first vertical slot 11a, pallet 12, expansion link 2, the first vertical ribs 21, rotational lead screw 3, drive motors 4, microphone 5 as Fig. 1.

The utility model embodiment, intelligent elevated microphone, include the base body 1 and the expansion link 2 that slide up and down cooperation, expansion link 2 tops are fitted with microphone 5, be inserted with rotational lead screw 3 in the middle of the base body 1, these rotational lead screw 3 tops and described expansion link 2 inner chambers are rotatably assorted, and control the operation up and down of this expansion link 2; Base body 1 bottom is furnished with drive motors 4, and these drive motors 4 output shafts are connected with rotational lead screw 3 bottoms, and the operation of control rotational lead screw 3; Microphone 5 head ends and tail end place all are furnished with sound transducer, and two sound transducers have formed control signal through the comparison circuit plate, and the operation of controlling and driving motor 4.Two bodies of rod that upper and lower sleeve is dressed up are set, utilize leading screw to drive, compact overall structure operates steadily, and the control accuracy height; All dispose the audio frequency comparator in the microphone front and back end, can judge according to speaker's sound, and draw suitable position, its integral power is provided by the motor of bottom, has promptly realized full automatic operation.
