Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-3, a conference room sound reinforcement device comprises a bottom plate 1 and a sound generator body 2, wherein the sound generator body 2 is embedded in the middle of the bottom plate 1, the bottom plate 1 and the sound generator body 2 are glued and fixed, two jacks 3 are symmetrically arranged on the bottom plate 1, the two jacks 3 are positioned on two sides of the sound generator body 2, a rotating plate 4 is inserted into each jack 3, the two rotating plates 4 are rotatably connected with a slide block 7 by using a pin shaft, the two slide blocks 7 are connected with an adjusting device together, two side plates 8 are symmetrically welded on the bottom plate 1, and the side plates 8 and the rotating plates 4 form a cover body together, so that more sounds emitted by the sound generator body 2 are transmitted towards the direction of the cover body;

the adjusting device comprises a power box 5, the power box 5 is welded on one side, far away from a side plate 8, of the bottom plate 1, a threaded rod 6 is in threaded connection with two sliding blocks 7 together, two ends of the threaded rod 6 are rotatably connected with the power box 5 through bearings, when the threaded rod 6 in the power box 5 rotates, the sliding blocks 7 are connected with the rotating plates 4 so that the sliding blocks cannot rotate relative to the threaded rod 6, the two sliding blocks 7 can slide on the threaded rod 6 together, and the two rotating plates 4 can rotate relative to the jacks 3;

the thread of the threaded rod 6 is divided into two sections, the rotating directions of the two sections of threads are opposite, the two sliding blocks 7 are respectively positioned on the two sections of threads, and the threaded rod 6 penetrates through the power box 5 and is connected with a power device, so that when the threaded rod 6 rotates, the moving directions of the two sliding blocks 7 are opposite.

The power device comprises a micro servo motor 11, a mounting plate 12 is welded on the bottom plate 1, the micro servo motor 11 is fixed on the mounting plate 12 through bolts, and the micro servo motor 11 can be a micro motor with the model of CYQ1718 and is electrically connected with a storage battery (not shown in the figure) in the power box 5.

The rotating plate 4 comprises a thin rod 41 and a baffle 42, the thin rod 41 and the baffle 42 are welded and fixed, the jack 3 is slightly larger than the thin rod 41, so that when the rotating plate 4 rotates, the jack 3 cannot limit the rotating plate 4, the joint of the baffle 42 and the thin rod 41 is glued with a rubber pad 9, the rubber pad 9 abuts against the bottom plate 1 and blocks the position of the jack 3, and the rotating plate 4 cannot generate vibration and other conditions which affect the tone quality of the sounder when the sounder body 2 works; the side wall of the baffle plate 42 is glued with the sealing rubber strip 10, so that the side wall of the baffle plate 42 is abutted against the side plate 8, and the connection is more tight.

In the utility model, when the participant needs to adjust the cover less, start the micro servo motor 11 to make it drive the threaded rod 6 to rotate, because two sliders 7 are respectively screwed on the threaded rod 6 to the opposite two-end screw thread, so two sliders 7 can reverse motion, here should make two sliders 7 keep away from each other, because slider 7 and rotor plate 4 rotate to be connected, and rotor plate 4 is inserted in the jack 3, the motion of slider 7 can drive rotor plate 4 to move, at this time rotor plate 4 can rotate around the jack 3, and then the cover shape formed by two rotor plates 4 and side plate 8 changes, namely the included angle of two rotor plates 4 becomes small, namely the direction angle that the cover faces becomes small, so that more sounds sent by the sounder body 2 are transmitted to the direction between the included angles of two rotor plates 4; so as to reduce the volume of other positions and reduce the noise pollution of other positions;

when the included angle of the two rotating plates 4 becomes small, if the power of the sounder body 2 is not changed, the volume of the direction towards which the cover body faces becomes large, if the original volume needs to be kept, the power of the sounder body 2 only needs to be properly reduced, and therefore the practical sound reinforcement equipment can realize a certain energy-saving effect.
