In the figure: 1. a protective housing; 2. a speaker main body; 3. a first fixing plate; 4. fixing the bolt; 5. a second fixing plate; 6. a dust cap; 7. a damping mechanism; 70. a guide bar; 71. an outer cylinder; 72. a damping spring; 73. a piston; 74. a viscous liquid.

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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Example 1:

referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a radium carving diaphragm speaker, including speaker main part 2, the diaphragm surface mark that the speaker used is that beat out with radium carving technique (the diaphragm is located inside the speaker, this is prior art), speaker main part 2 top is equipped with first fixed

plate

3, 3 tops of first fixed plate are equipped with second fixed

plate

5, 5 tops of second fixed plate are equipped with

dust cap

6, 5 tops of second fixed plate are run through and are equipped with four groups of fixing bolt 4, four groups and 4 assorted screw holes of fixing bolt are seted up at first fixed plate 3 tops, first fixed plate 3 and second fixed plate 5 are the ring form and set up, four groups of fixing bolt 4 are ring array and distribute at 5 tops of second fixed plate, speaker main part 2 outside is equipped with protecting sheathing 1, protecting sheathing 1 is the toper form setting, and 2 outer wall phase-match of speaker main part, be equipped with multiunit damper 7 between protecting sheathing 1 inner wall and speaker main part 2 outer walls, multiunit damper 7 is ring array and distributes between protecting sheathing 1 inner wall and speaker main part 2 outer walls, thereby can be better carry out shock attenuation protection to the speaker.

Referring to fig. 2-3, the damping mechanism 7 includes an outer cylinder 71 disposed on an inner wall of the protective housing 1, a guide rod 70 is disposed through a left side wall of the outer cylinder 71, one end of the guide rod 70 is connected to an outer wall of the speaker body 2, a viscous liquid 74 is disposed in the outer cylinder 71, a piston 73 is slidably disposed on the inner wall of the outer cylinder 71, one end of the guide rod 70 is connected to a side wall of the piston 73, a damping spring 72 is sleeved on the outer wall of the outer cylinder 71, one end of the damping spring 72 is connected to the inner wall of the protective housing 1, and the other end of the damping spring 72 is connected to the outer wall of the speaker body 2.
