Abstract

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include a circuit housing, an ear hook, a rear hook, a loudspeaker component, and a magnetic connector. The circuit housing may be configured to accommodate a control circuit or a battery component. The ear hook may be connected to one end of the circuit housing and at least partially covered by a first protective housing. The rear hook connected to another end of the circuit housing and at least partially covered by a second protective housing. The magnetic connector may be configured to absorb a charging interface of an external power source to establish an electrical connection so as to charge the loudspeaker apparatus.

First claim

We claim:

1. A loudspeaker apparatus, comprising:
a first housing;
an ear hook connected to one end of the first housing;
a second housing connected to one end of the ear hook, the second housing accommodating an earphone core configured to generate sound; and
a magnetic connector configured to charge the loudspeaker apparatus, wherein the magnetic connector includes:
a magnetic adsorption ring;
an insulation base including at least two accommodating holes, at least part of the insulation base being inserted into the magnetic adsorption ring; and
a first terminal and a second terminal, each of which being inserted into a corresponding accommodation hole, wherein an outer end of the first terminal and an outer end of the second terminal are visibly seen from a direction facing a top surface of the insulation base so as to form a first contact surface and a second contact surface.

2. The loudspeaker apparatus of claim 1 , wherein the magnetic adsorption ring has a shape of a circular ring, an elliptical ring, or a rectangular ring.

3. The loudspeaker apparatus of claim 1 , wherein the magnetic adsorption ring includes at least two arc sections arranged in a circumferential direction.

4. The loudspeaker apparatus of claim 3 , wherein outer ends of adjacent arc sections have different magnetic polarities.

5. The loudspeaker apparatus of claim 1 , wherein the outer end of the first terminal and the outer end of the second terminal flush with the top surface of the insulation.

6. The loudspeaker apparatus of claim 1 , wherein the magnetic connector has a 180 degrees rotationally symmetrical shape with respect to a symmetry point.

7. The loudspeaker apparatus of claim 6 , wherein a dimension of the magnetic adsorption ring in a first direction passing through the symmetry point is different from a dimension of the magnetic adsorption ring in a second direction perpendicular to the first direction passing through the symmetry point.

8. The loudspeaker apparatus of claim 1 , wherein each of the first terminal and the second terminal has a shape of a cylinder.

9. The loudspeaker apparatus of claim 1 , wherein
the insulation base includes a supporting member and an insertion member,
a cross-section area of the supporting member is larger than that of the insertion member to form a supporting table,
the insertion member is inserted into the magnetic adsorption ring, and
the magnetic adsorption ring is supported by the supporting table.

10. The loudspeaker apparatus of claim 9 , wherein the magnetic connector further includes a housing, and the housing includes a body and a flange located at an outer end of the body and protruding into the body, wherein the body is sleeved on the periphery of the insulation base and the magnetic adsorption ring.

11. The loudspeaker apparatus of claim 10 , wherein the flange covers an outer end of the magnetic adsorption ring.

12. The loudspeaker apparatus of claim 1 , wherein
the magnetic adsorption ring has a shape of a circular ring with a symmetry point as a center, and
each of the first contact surface and the second contact surface has a shape concentrically arranged with the magnetic adsorption ring.

13. The loudspeaker apparatus of claim 1 , wherein the first housing is configured to accommodate a battery assembly, the battery assembly including:
a battery; and
a flexible circuit board connected to the battery, wherein a first region of the flexible circuit board is bent towards the battery such that a second region of the flexible circuit board is attached to a side surface of the battery, wherein the earphone core is electrically connected to the flexible circuit board by wires and receives electronic power from the battery to generate the sound.

14. The loudspeaker apparatus of claim 13 , wherein one end of the first region is connected to the battery and an opposite end of the first region is connected to the second region of the flexible circuit board.

15. The loudspeaker apparatus of claim 14 , wherein the flexible circuit board includes a plurality of bonding pads, and two of the plurality of bonding pads are electrically connected to a positive terminal and a negative terminal of the battery by flexible leads.

16. The loudspeaker apparatus of claim 15 , wherein the plurality of bonding pads are arranged on the second region of the flexible circuit board, and the flexible leads are arranged on the first region of the flexible circuit board.

17. The loudspeaker apparatus of claim 14 , wherein the battery includes a body region and a sealing region, a side surface of the sealing region and a side surface of the body region form a step structure.

18. The loudspeaker apparatus of claim 17 , wherein the second region of the flexible circuit board is attached to the sealing region of the battery.

19. The loudspeaker apparatus of claim 17 , wherein the battery includes a hard circuit board arranged on another side surface of the sealing region, and the battery includes a positive terminal and a negative terminal both of which are arranged on the hard circuit board.

20. The loudspeaker apparatus of claim 19 , wherein the end of the first region which is connected to the battery is fixedly attached to the hard circuit board.
