Compared with the prior art, the technical scheme of the invention has the following beneficial effects:
1. according to the damping structure of the loudspeaker unit, the loudspeaker unit is fixed on the connecting screw through the buffer sleeve. The loudspeaker unit only has the atress transmission with the buffer cover, does not have the contact with other objects, and sound energy only can go out through the buffer cover transmission, buffer cover top and connecting screw top contact, and other faces do not have the contact, reduce sound energy transmission like this to the purpose of vibration has been reached.
2. According to the damping structure of the loudspeaker unit, a section of the second clamping groove is added on the buffer sleeve, so that energy transmission of the buffer sleeve can be softened, and vibration energy is reduced.
3. According to the shock absorption structure of the loudspeaker unit, the second straight section without the screw teeth is arranged in the connecting screw, so that the screw is prevented from being locked continuously, the screw is prevented from extruding the buffer sleeve, and the loudspeaker unit is prevented from falling off due to deformation of the buffer sleeve.

Detailed Description
In order to make the technical scheme of the invention clearer, the invention is further described in detail by combining an embodiment and the attached drawings:
referring to fig. 3 and 4, a shock absorbing structure of a speaker unit includes: a speaker unit 1, a speaker unit bracket 2, a buffer sleeve 3 and a connecting screw 4;
the upper end face of the loudspeaker unit bracket 2 is provided with a threaded hole 21, the buffer sleeve 3 is sleeved outside the threaded hole 21, and the upper end of the buffer sleeve 3 protrudes outside the threaded hole 21; the inner wall of the part of the buffer sleeve 3 protruding outwards from the threaded hole 21 extends towards the direction of approaching each other, so that the buffer sleeve covers the upper end face of the threaded hole 21; this allows the cushion cover 3 to be disposed between the coupling screw 4 and the screw hole 21.
The buffer sleeve 3 is positioned in the part outside the side wall of the threaded hole 21, and the inner diameter of the buffer sleeve is larger than the outer diameter of the threaded hole 21, so that the buffer sleeve 3 is positioned in the part outside the side wall of the threaded hole 21, and the inner side wall is not contacted with the outer side wall of the threaded hole 21; therefore, only the portion of the cushion cover 3 covering the upper end face of the screw hole 21 is in direct contact with the speaker unit holder 2, reducing the contact area therebetween. The buffer sleeve 3 is positioned in the part outside the side wall of the threaded hole 21, and a clamping groove 211 for fixing the loudspeaker unit 1 is arranged along the circumferential direction;
after the above structural improvement, the buffer sleeve 3 is fixedly connected with the threaded hole 21 through the connecting screw 4, and the speaker unit 1 is directly contacted with the buffer sleeve 3 only. The loudspeaker unit 1 only has the atress transmission with the cushion cover 3, does not have the contact with other objects, and sound energy can only pass through cushion cover 3 and go out, cushion cover 3 top and connecting screw 4 top contact, and other faces do not have the contact, reduce sound energy transmission like this to the purpose of vibration has been reached.
The buffer sleeve 3 is located at a portion outside the side wall of the threaded hole 21, and further has second clamping grooves 212 spaced apart from the clamping grooves 211 in parallel along the circumferential direction. A section of second clamping groove 212 is added on the buffer sleeve 3, so that energy transmission of the buffer sleeve 3 can be softened, and vibration energy is reduced.
The connecting screw 4 comprises a first straight section 41 and a second straight section 42 connected in axial direction; the diameter 41 of the first straight section is larger than that of the second straight section 42, and the length of the first straight section 41 corresponds to the height of the part of the buffer sleeve 3 protruding outwards from the threaded hole 21; the outer surface of the second straight section 42 is provided with threads; the connecting screw 4 is fixedly connected with the threaded hole 21 through the second straight section 42, and the first straight section 41 protrudes outwards from the second straight section 42, the lower end surface of the connecting screw abuts against the top end surface of the threaded hole 21, and the connecting screw is limited downwards along the axial direction.
Since the connecting screw 4 has the second straight section 42 without screw teeth, the screw is prevented from being locked further, the screw is prevented from extruding the buffer sleeve 3, and the buffer sleeve 3 is prevented from being deformed to cause the loudspeaker unit 1 to fall off.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
