The diameter for stating the first straight section is greater than the second straight section, and the length of the first straight section and the cushion collar externally protrude out in the part of threaded hole
Height it is corresponding；The outer surface of second straight section is provided with screw thread；The attachment screw is solid by the second straight section and threaded hole
Fixed connection, and the first straight section externally protrude out in the part of the second straight section, the top end face contact of lower end surface and threaded hole, along axis
To lower limit.
Compared to the prior art, the technical solution of the utility model have it is following the utility model has the advantages that
1. a kind of shock-damping structure of loudspeaker unit provided by the utility model, loudspeaker unit are fixed on by cushion collar
On attachment screw.Loudspeaker unit is only cased with stress transmitting with buffering, does not contact with other objects, acoustic energy can only lead to
It crosses cushion collar to pass, be contacted at the top of cushion collar with attachment screw top, lap does not contact, in this way reduction acoustic energy
Transmitting, to achieve the purpose that reduce vibration.
2. a kind of shock-damping structure of loudspeaker unit provided by the utility model, a section second card is increased on cushion collar
Slot can soften cushion collar energy transmission, to reduce vibration energy.
3. a kind of shock-damping structure of loudspeaker unit provided by the utility model, there is one section of not thread in attachment screw
Second straight section prevents screw from continuing lower lock, prevents screw from squeezing cushion collar, and playing prevents cushion collar deformation from causing loudspeaker unit
It falls off.

Specific embodiment
In order to keep technical solutions of the utility model clearer, now the utility model is done in conjunction with the embodiments with attached drawing into one
Step is described in detail:
With reference to Fig. 3, Fig. 4, a kind of shock-damping structure of loudspeaker unit, comprising: loudspeaker unit 1, loudspeaker unit bracket
2, cushion collar 3 and attachment screw 4；
The upper surface of the loudspeaker unit bracket 2 is provided with threaded hole 21, and the cushion collar 3 is set in threaded hole 21
Outside, and the upper end of cushion collar 3 externally protrudes out in threaded hole 21；The cushion collar 3 externally protrude out in the inner wall of the part of threaded hole 21 towards
Direction close to each other extends, it is made to be covered on the top of 21 upper surface of threaded hole；Thus allow the setting of cushion collar 3 in connection
Between screw 4 and threaded hole 21.
The cushion collar 3 is located in the part outside 21 side wall of threaded hole, and internal diameter is greater than the outer diameter of threaded hole 21, so that slow
Punching set 3 is located in the part outside 21 side wall of threaded hole, and the lateral wall of inner sidewall and threaded hole 21 is not in contact；Therefore, it buffers
Both set 3, which is only covered on the part of the top of 21 upper surface of threaded hole and loudspeaker unit bracket 2, direct contact, reduce
Contact area.The cushion collar 3 is located in the part outside 21 side wall of threaded hole, and fixed loudspeaker unit 1 is circumferentially arranged
Card slot 211；
After being improved by above-mentioned structure, the cushion collar 3 is fixedly connected by attachment screw 4 with threaded hole 21, and
Loudspeaker unit 1 has and only directly contacts with cushion collar 3.Loudspeaker unit 1 only has stress transmitting with cushion collar 3, with other
Object does not contact, and acoustic energy can only be passed by cushion collar 3, the top of cushion collar 3 with contacted at the top of attachment screw 4,
Its lap does not contact, in this way the transmitting of reduction acoustic energy, to achieve the purpose that reduce vibration.
The cushion collar 3 is located in the part outside 21 side wall of threaded hole, circumferentially also has parallel with the card slot 211
Spaced second card slot 212.Second card slot of section 212 is increased on cushion collar 3, can soften 3 energy transmission of cushion collar,
To reduce vibration energy.
The attachment screw 4 includes the first straight section 41 and the second straight section 42 axially connected；First straight section
41 diameters are greater than the second straight section 42, and the length of the first straight section 41 and the cushion collar 3 externally protrude out in the part of threaded hole 21
Height is corresponding；The outer surface of second straight section 42 is provided with screw thread；The attachment screw 4 passes through the second straight section 42 and threaded hole
21 are fixedly connected, and the first straight section 41 externally protrude out in the part of the second straight section 42, the top end face of lower end surface and threaded hole 21
Contact limits axially down.
Due to there is second straight section 42 of one section of not no thread to prevent spiral shell for preventing screw from continuing lower lock in attachment screw 4
Nail squeezes cushion collar 3, and playing prevents the deformation of cushion collar 3 from loudspeaker unit 1 being caused to fall off.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
