Loudspeaker device

1. A loudspeaker device, comprising:

a support connector configured to be in contact with a head, the support connector including an ear hook; and

at least one speaker component, the at least one speaker component including an earphone core and a core housing for accommodating the earphone core, the core housing being fixedly connected to the support connector, the core housing being provided with a key module; wherein

when the loudspeaker device is in a wearing state, a distance between a center of the key module and a top end of the ear hook is not greater than a distance between a center of the core housing and the top end of the ear hook.

2. The loudspeaker device of claim 1 , wherein

the top end of the ear hook is a vibration fulcrum of a reciprocating swing movement of the at least one speaker component when the at least one speaker component vibrates, and

a portion of the ear hook between the top end of the ear hook and the at least one speaker component is an arm of the reciprocating swing movement.

3. The loudspeaker device of claim 2 , wherein the core housing includes an outer side wall away from the head and a peripheral side wall connected to and surrounding the outer side wall.

4. The loudspeaker device of claim 3 , wherein:

the peripheral side wall includes a first peripheral side wall disposed along a length direction of the outer side wall and a second peripheral side wall disposed along a width direction of the outer side wall; and

the outer side wall and the peripheral side wall are connected together to form a cavity with an open end and accommodating the earphone core.

5. The loudspeaker device of claim 4 , wherein the key module is located at a middle position of the outer side wall, or the key module is located between the middle position and a top position of the outer side wall.

6. The loudspeaker device of claim 4 , wherein

there is a third distance between a top of the key module and a top end position of the first peripheral side wall,

there is a fourth distance between a bottom of the key module and a bottom end position of the first peripheral side wall,

wherein a ratio of the third distance to the fourth distance is not greater than 1.

7. The loudspeaker device of claim 6 , wherein

the ratio of the third distance to the fourth distance is not greater than 0.95.

8. The loudspeaker device of claim 7 , wherein

the ratio of the third distance to the fourth distance is not greater than 0.7.

9. The loudspeaker device of claim 3 , wherein

there is a first distance between a top of the key module and a top end position of the outer side wall;

there is a second distance between a bottom of the key module and a bottom end position of the outer side wall;

a ratio of the first distance to the second distance is not greater than 1.

10. The loudspeaker device of claim 9 , wherein the ratio of the first distance to the second distance is not greater than 0.95.

11. The loudspeaker device of claim 10 , wherein the ratio of the first distance to the second distance is not greater than 0.7.

12. The loudspeaker device of claim 3 , wherein

the key module includes a key and an elastic bearing for supporting the key, and

the outer side wall is provided with a key hole matching the key.

13. The loudspeaker device of claim 1 , wherein the center of the key module or the center of the core housing is a center of mass or a centroid.

14. The loudspeaker device of claim 1 , wherein a connection portion connecting the ear hook and the core housing includes a central axis, an extension line of the central axis having a projection on a plane where an outer side surface of the key module is located, an angle between the projection and a long axis direction of the key module being less than 10°.

15. The loudspeaker device of claim 14 , wherein the angle between the projection and the long axis direction of the key module being less than 7°.

16. The loudspeaker device of claim 14 , wherein the projection of the extension line of the central axis of the ear hook on the plane where the outer side surface of the key module locates coincides with the long axis direction of the key module.

17. The loudspeaker device of claim 14 , wherein there is an intersection between the long axis direction and a short axis direction of the outer side surface of the key module, there being a shortest distance between the projection and the intersection, the shortest distance being smaller than a size of the outer side surface of the key module in the short axis direction.

18. The loudspeaker device of claim 1 , wherein

there is a first distance between the center of the key module and the top end of the ear hook,

there is a second distance between the center of the core housing and the top end of the ear hook, and

a ratio between the first distance and the second distance is not greater than 0.95.

19. The loudspeaker device of claim 18 , wherein the ratio between the first distance and the second distance is not greater than 0.90.

20. The loudspeaker device of claim 1 , wherein a ratio of a mass of the key module and a mass of the speaker component is not greater than 0.3.
