Abstract

The present disclosure provides a fixing assembly and a wearing device of a bone conduction vibrator, comprising: an elastic fixing portion, the elastic fixing portion being in a form of a band structure, the elastic fixing portion including a first position and a second position, the first position and the second position being disposed at intervals along a length direction of the elastic fixing portion; and a fixing member, configured to fix the elastic fixing portion around a wearing object, so that the bone conduction vibrator is located between the elastic fixing portion and the wearing object. When the elastic fixing portion surrounds the wearing object and is in a natural state, the fixing member fits into the first position of the elastic fixing portion; when the fixing member fits into the second position, the elastic fixing portion provides the bone conduction vibrator with a pressure acting on the wearing object, and the pressure is within a preset pressure range.

First claim

What is claimed is:

1. A fixing assembly of a bone conduction vibrator, comprising:
an elastic fixing portion, the elastic fixing portion being in a form of a band structure, the elastic fixing portion including a first position and a second position, the first position and the second position being disposed at intervals along a length direction of the elastic fixing portion; and
a fixing member, configured to fix the elastic fixing portion around a wearing object, so that the bone conduction vibrator is located between the elastic fixing portion and the wearing object;
wherein when the elastic fixing portion surrounds the wearing object and is in a natural state, the fixing member fits into the first position of the elastic fixing portion; when the fixing member fits into the second position, the elastic fixing portion provides the bone conduction vibrator with a pressure acting on the wearing object, and the pressure is within a preset pressure range.

2. The fixing assembly of claim 1 , wherein a product of a distance between the first position and the second position and an elastic coefficient of the elastic fixing portion is within the preset pressure range, the preset pressure range being 0.2 N-2 N.

3. The fixing assembly of claim 1 , wherein the elastic fixing portion is provided with multiple buckle holes disposed at intervals along the length direction thereof, the multiple buckle holes including at least one fixing buckle hole, the fixing buckle hole being located at the second position; the fixing member being a buckle member, the buckle member including a buckle, the buckle being inserted into the buckle hole so that the elastic fixing portion surrounds the wearing object.

4. The fixing assembly of claim 3 , wherein the multiple buckle holes are equally arranged along the length direction on the elastic fixing portion; the first position is located between two adjacent buckle holes, the fixing buckle hole is an m-th buckle hole from the first position, and when the buckle is inserted into the fixing buckle hole, the pressure is F 0 ×(x 1 /x 2 +m−1), wherein F 0 ×(x 1 /x 2 +m−1) is within the preset pressure range, x 1 denotes a distance between the first position and the 1st buckle hole at a side of the elastic fixing portion away from the fixing member relative to the first position, x 2 denotes a distance between two adjacent buckle holes, and F 0 denotes a tensioning force of the elastic fixing portion when a deformation of the elastic fixing portion is equal to a distance between two adjacent buckle holes.

5. The fixing assembly of claim 3 , wherein the multiple buckle holes are equally arranged along the length direction on the elastic fixing portion; the first position is located at a position of one of the multiple buckle holes, the fixing buckle hole is an m-th buckle hole on a side away from the fixing member relative to the first position in an extension direction of the elastic fixing portion, and when the buckle is inserted into the fixing buckle hole, the pressure is m×F 0 , wherein m×F 0 is within the preset pressure range and F 0 denotes a tensioning force of the elastic fixing portion when a deformation of the elastic fixing portion is equal to a distance between two adjacent buckle holes.

6. The fixing assembly of claim 4 , wherein F 0 is less than or equal to a maximum threshold of the preset pressure range.

7. The fixing assembly of claim 1 , wherein the elastic fixing portion includes a first band body and a second band body, wherein the first band body is used to at least partially elastically surround a head of the wearing object and the second band body is used to at least partially elastically surround a neck of the wearing object; wherein the fixing member is connected to the elastic fixing portion and fixes the bone conduction vibrator to the head of the wearing object.

8. The fixing assembly of claim 7 , wherein the first band body and the second band body are provided side by side, the elastic fixing portion further includes a connection portion, and the connection portion is used to connect the first band body and the second band body, wherein the connection portion is located in a central region along a length direction of the first band body or the second band body.

9. The fixing assembly of claim 8 , wherein the fixing member is provided on a side of the bone conduction vibrator away from the head of the wearing object, the fixing member is provided with a buckle column extending away from the bone conduction vibrator, and the first band body and the second band body are respectively provided with multiple first buckle holes and multiple second buckle holes disposed at intervals along their respective length directions for insertion of the buckle column.

10. The fixing assembly of claim 9 , wherein the multiple first buckle holes are symmetrically arranged on the first band body with the connection portion as the center, and the multiple second buckle holes are symmetrically arranged on the second band body with the connection portion as the center.

11. The fixing assembly of claim 9 , wherein the buckle column includes a first buckle column and a second buckle column disposed at intervals from each other along an interval direction of the first band body and the second band body, wherein the first buckle column is inserted into the first buckle hole and the second buckle column is inserted into the second buckle hole.

12. The fixing assembly of claim 7 , wherein the fixing member includes a buckle member, the elastic fixing portion includes a third band body, one end of the first band body and one end of the second band body being jointly connected to the third band body, the other end of the first band body and the other end of the second band body being jointly connected to the buckle member, the buckle member being further provided with a buckle column, the third band body being provided with a plurality of buckle holes disposed at intervals along a length direction thereof for insertion of the buckle column.

13. The fixing assembly of claim 12 , wherein the fixing member is provided on a side of the bone conduction vibrator away from the head of the wearing object, the fixing member is provided with a first hook member and a second hook member extending away from the bone conduction vibrator, wherein the first hook member and the second hook member are disposed at intervals from each other in an interval direction of the first band body and the second band body, one end of the first hook member away from the fixing member extends toward the second hook member to form a free end of the first hook member, one end of the second hook member away from the fixing member extends toward the first hook member to form a free end of the second hook member, an opening is formed between the free end of the first hook member and the free end of the second hook member, and a size of the opening is less than a distance between the first band body and the second band.
