Abstract

A buffer member includes a first buffer portion, a pin, a bending portion and a second buffer portion. The pin is located on the first buffer portion. The bending portion is connected with the first buffer portion. The second buffer portion is connected with the bending portion, and the first buffer portion is connected with the second buffer portion via the bending portion. A reinforcing member is located inside the pin for raising the rigidity of the pin. The pin is used for fixing a vibration source. The first buffer portion and the second buffer portion reduce the transmission of the vibration energy from the vibration source.

Claims

1. A buffer member, comprising:

a first buffer portion;

a pin located on the first buffer portion;

a bending portion connected with the first buffer portion;

a second buffer portion connected with the bending portion, wherein the first buffer portion is connected with the second buffer portion via the bending portion; and

a reinforcing member, wherein the hardness of the reinforcing member is higher than that of the first buffer portion, the pin, the bending portion and the second buffer portion, and the reinforcing member is located inside the pin;

wherein the reinforcing member is substantially coaxial with the pin, the pin has a first end and a second end opposite to each other, the second end is closer to the first buffer portion than the first end, and the reinforcing member does not protrude from the first end.

2. The buffer member according to claim 1, wherein the buffer member further comprises an engaging projection located on the second buffer portion.

3. The buffer member according to claim 2, wherein the buffer member further comprises an adhesive layer located on the second buffer portion, the adhesive layer and the engaging projection are located at the same side of the second buffer portion.

4. The buffer member according to claim 3, wherein the outer diameter of the pin is gradually increased along a direction facing toward the first buffer portion.

5. The buffer member according to claim 3, wherein the pin has a mounting hole where the reinforcing member is detachably located on.

6. The buffer member according to claim 2, wherein a thread, a texture or a plurality of projections are located on an outer surface of the pin.

7. The buffer member according to claim 1, wherein the reinforcing member has no screw thread.

8. The buffer member according to claim 1, wherein a width of the bending portion is smaller than a width of the first buffer portion and a width of the second buffer portion.

9. The buffer member according to claim 1, wherein the first buffer portion, the pin, the bending portion and the second buffer portion are physically integral with each other.

10. A buffer member, comprising:

a first buffer portion;

a pin located on the first buffer portion;

a bending portion connected with the first buffer portion;

a second buffer portion connected with the bending portion, wherein the first buffer portion is connected with the second buffer portion via the bending portion; and

a reinforcing member located inside the pin, wherein the hardness of the reinforcing member is higher than that of the first buffer portion, the pin, the bending portion and the second buffer portion, and the reinforcing member has no screw thread,

wherein the pin has a first end and a second end opposite to each other, the second end is closer to the first buffer portion than the first end, and the reinforcing member does not protrude from the first end.

11. An electrical device, comprising:

a speaker has a top surface and a bottom surface which is opposite to the top surface, and the top surface has at least an opening; and

a buffer member, comprising;

a first buffer portion;

a pin located on the first buffer portion, and the pin passes through the opening of the speaker;

a bending portion connected with the first buffer portion; and

a second buffer portion connected with the bending portion, wherein the first buffer portion is connected with the second buffer portion via the bending portion, and the second buffer portion is attached to the bottom surface of the speaker; and

a reinforcing member, wherein the hardness of the reinforcing member is higher than that of the first buffer portion, the pin, the bending portion and the second buffer portion, and the reinforcing member is located inside the pin,

wherein the pin has a first end and a second end opposite to each other, the second end is closer to the first buffer portion than the first end, and the reinforcing member does not protrude from the first end.

12. The electrical device according to claim 11, wherein the top surface of the speaker has a recess, wherein the opening is located on the recess and the first buffer portion is attached to the recess.

13. The electrical device according to claim 12, wherein the speaker further comprises a lateral surface which is located between the top surface and the bottom surface, the lateral surface has a groove which extends toward the bottom surface from the top surface, and the bending portion is detachably located on the groove.
