Abstract

The present disclosure discloses a bone conduction earphone. The bone conduction earphone may include a loudspeaker assembly. The bone conduction earphone may also include an ear hook assembly including a first ear hook housing, a connection member, and a second ear hook housing. One end of the connection member may be connected to the first ear hook housing, and the other end of the connection member may be connected to the loudspeaker assembly. The first ear hook housing may include a first sub-accommodating space, and the second ear hook housing may include a second sub-accommodating space. The first ear hook housing may be spliced and matched with the second ear hook housing by a first connection assembly such that the first sub-accommodating space and the second sub-accommodating space may be combined to form an accommodating space, and a length direction of the accommodating space may be perpendicular to a thickness direction of the accommodating space.

First claim

What is claimed is:

1. A bone conduction earphone, comprising:
a loudspeaker assembly; and
an ear hook assembly including a first ear hook housing, a connection member, and a second ear hook housing, wherein
one end of the connection member is connected to the first ear hook housing, and the other end of the connection member is connected to the loudspeaker assembly;
the first ear hook housing includes a first sub-accommodating space, the second ear hook housing includes a second sub-accommodating space, the first ear hook housing is spliced and matched with the second ear hook housing by a first connection assembly such that the first sub-accommodating space and the second sub-accommodating space are combined to form an accommodating space, and a length direction of the accommodating space is perpendicular to a thickness direction of the accommodating space; and
a splicing edge of the first ear hook housing are matched with a splicing edge of the second ear hook housing to restrict the relative movement of the first ear hook housing and the second ear hook housing along the length direction.

2. The bone conduction earphone of claim 1 , wherein
the first connection assembly includes a first slot and a first block;
one of the first slot and the block is arranged on the first ear hook housing, and the other of the first slot and the block is arranged on the second ear hook housing; and
the first block is matched and stuck connected to the first slot to restrict a relative movement of the first ear hook housing and the second ear hook housing along the length direction and the thickness direction.

3. The bone conduction earphone of claim 2 , wherein
the first slot is arranged on the first ear hook housing, an opening direction of the first slot facing the first accommodating space; and
the first block is arranged on the second ear hook housing, the first block being configured to be matched and stuck connected to the first slot.

4. The bone conduction earphone of claim 3 , wherein
the first ear hook housing is configured with an outer side hole segment and an inner side hole segment that communicate with each other from outside of the first sub-accommodating space to inside of the first sub-accommodating space, the outer side hole segment being filled with a filling member, and the inner side hole segment being designated as the first slot.

5. The bone conduction earphone of claim 4 , wherein a cross-sectional area of the outer side hole segment perpendicular to a communication direction of the outer side hole segment and the inner side hole segment is greater than a cross-sectional area of the inner side hole segment perpendicular to the communication direction of the outer side hole segment and the inner side hole segment.

6. The bone conduction earphone of claim 2 , wherein
the first connection assembly further includes a second slot and a second block;
one of the second slot and the second block is arranged on the first ear hook housing, and the other of the second slot and the second block is arranged on the second ear hook housing; and
the second slot is matched and stuck connected to and the second block to restrict a relative movement of the first ear hook housing and the second ear hook housing along a splicing direction, the splicing direction being perpendicular to the length direction and the thickness direction.

7. The bone conduction earphone of claim 6 , wherein
the first ear hook housing is configured with the second slot, the first slot and the second slot being arranged along the length direction and having a same opening direction; and
the second ear hook housing is protrudingly configured with the second block, the first block being arranged opposite to the first slot along the length direction, and the second block being arranged opposite to the second slot along the length direction.

8. The bone conduction earphone of claim 7 , wherein the first slot and the second slot are arranged at intervals along the length direction.

9. The bone conduction earphone of claim 8 , wherein
the first slot and the second slot are arranged on two sides of the first ear hook housing along the length direction, respectively, the opening direction of the first slot facing the first sub-accommodating space, and the opening direction of the second slot being away from the first sub-accommodating space; and
the first block and the second block are arranged on two sides of the second ear hook housing along the length direction, respectively, an extension direction of the first block being away from the second sub-accommodating space, and an extension direction of the second block facing the second sub-accommodating space.

10. The bone conduction earphone of claim 7 , wherein
the first slot is arranged on a side of the first ear hook housing close to the connection member; and
the second slot is arranged on a side of the first ear hook housing away from the connection member.

11. The bone conduction earphone of claim 10 , wherein
part of the second ear hook housing away from the connection member is configured with a power plug-in hole, the power plug-in hole communicating with the accommodating space, and the power plug-in hole being configured to accommodate a power supply interface;
the second block is arranged adjacent to the power plug-in hole, and the second block is closer to the accommodating space than the power plug-in hole; and
a projection of the second block and a projection of the power plug-in hole on a first reference plane perpendicular to the length direction overlap each other.

12. The bone conduction earphone of claim 11 , wherein the projection of the second block and the projection of the power plug-in hole on a second reference plane perpendicular to the splicing direction overlap each other.

13. The bone conduction earphone of claim 1 , wherein
a splicing edge of the first ear hook housing is configured with a first blocking part, and a splicing edge of the second ear hook housing is configured with a second blocking part; and
the first blocking part is matched with the second blocking part to restrict the relative movement of the first ear hook housing and the second ear hook housing along the length direction.

14. The bone conduction earphone of claim 1 , wherein
the connection member includes an ear hook elastic metal filament, a joint part, and an ear hook elastic cover layer, the joint part being connected to one end of the ear hook elastic metal filament, the ear hook elastic cover layer at least covering the ear hook elastic metal filament, and the joint part being configured to be plugged and matched with the loudspeaker assembly;
