Abstract

A loudspeaker apparatus includes a circuit housing configured to accommodate a circuit component or a battery; an ear hook; a housing of an earphone core configured to accommodate the earphone core; and a housing protector at least partially covering a periphery of the circuit housing and the ear hook. A first end of the ear hook is connected to the circuit housing. The earphone core is driven by the circuit component or the battery to vibrate to generate sound. The housing of the earphone core is connected to a second end of the ear hook away from the circuit housing through a hinge component. The hinge component is capable of rotating to change a position of the housing of the earphone core relative to the ear hook.

First claim

What is claimed is:

1. A loudspeaker apparatus, comprising:
a circuit housing, configured to accommodate a circuit component or a battery;
an ear hook, wherein a first end of the ear hook is connected to the circuit housing;
a housing of an earphone core, configured to accommodate the earphone core, wherein the earphone core is driven by the circuit component or the battery to vibrate to generate sound, the housing of the earphone core is connected to a second end of the ear hook away from the circuit housing through a hinge component, and the hinge component is capable of rotating to change a position of the housing of the earphone core relative to the ear hook so that the housing of the earphone core fits in front of or behind an ear of a user; and
a housing protector, wherein the housing protector at least partially covers a periphery of the circuit housing and the ear hook, and the housing protector is made of a waterproof material.

2. The loudspeaker apparatus of claim 1 , wherein the housing protector includes a bag-like structure with an open end, so that the circuit housing enters an interior of the housing protector through the open end of the housing protector.

3. The loudspeaker apparatus of claim 2 , wherein the open end of the housing protector is disposed with an annular flange protruding inward, and when the housing protector covers the periphery of the circuit housing, the annular flange abuts an end of the circuit housing away from the ear hook.

4. The loudspeaker apparatus of claim 3 , wherein a sealant is applied to a joint region of the annular flange and the end of the circuit housing away from the ear hook to seal the housing protector and the circuit housing.

5. The loudspeaker apparatus of claim 3 , wherein the end of the circuit housing away from the ear hook includes a first annular table surface, and the first annular table surface is snap-connected to the annular flange to position the housing protector.

6. The loudspeaker apparatus of claim 5 , wherein the first annular table surface is disposed with a positioning block extending in a direction away from the ear hook, and the annular flange of the housing protector is disposed with a positioning slot corresponding to the positioning block; wherein the positioning slot is configured to accommodate at least a portion of the positioning block to position the housing protector.

7. The loudspeaker apparatus of claim 3 , wherein
the circuit housing comprises two sub-housings fastened to each other,
the housing protector completely covers a joint seam of the two sub-housings, and
a joint surface of the two sub-housings that are fastened to each other comprises a stepped structure that fits into each other.

8. The loudspeaker apparatus of claim 3 , wherein the circuit housing is disposed with a plurality of mounting holes, and an outer surface of the circuit housing is disposed with a first gum slot; wherein the plurality of mounting holes are located in the first gum slot; and
the loudspeaker apparatus further includes conductive pillars respectively inserted into the plurality of mounting holes, and the housing protector further includes an exposure hole that allows the conductive pillars to be exposed;
wherein a sealant is applied in the first gum slot to seal the housing protector and the circuit housing at a periphery of the plurality of mounting holes.

9. The loudspeaker apparatus of claim 8 , further including an auxiliary plate, wherein the auxiliary plate includes a plate body, and the plate body is disposed with a hollowed-out area; wherein the plate body is disposed on an inner surface of the circuit housing, the plurality of mounting holes are located inside the hollow-out area, and a second gum slot is formed on a periphery of the conductive pillar; wherein a sealant is applied in the second gum slot to seal the plurality of mounting holes inside the circuit housing.

10. The loudspeaker apparatus of claim 1 , wherein the housing of the earphone core is disposed with a socket hole; wherein
the ear hook includes an elastic metal wire and a plug end disposed at one end of the elastic metal wire, wherein the plug end is plugged into the socket hole.

11. The loudspeaker apparatus of claim 10 , wherein a stop block is disposed on an inner sidewall of the socket hole; and
the plug end includes:
an insertion portion that is at least partially inserted into the socket hole and abuts on an outer surface of the stop block;
two elastic hooks that are disposed on a side of the insertion portion facing an interior of the housing of the earphone core, wherein the two elastic hooks are capable of being close to each other under an action of an external thrust and the stop block and being elastically restored to be stuck on an inside surface of the stop block after passing through the stop block, thereby achieving the fixing of the housing of the earphone core and the plug end.

12. The loudspeaker apparatus of claim 11 , wherein the insertion portion is partially inserted into the socket hole, and an exposed portion of the insertion portion is set as a stair-step shape, thereby forming a second annular table surface spaced from an outer end surface of the housing of the earphone core; and
the ear hook further includes a protective sleeve disposed on a periphery of the elastic metal wire and the plug end; wherein the protective sleeve further extends to a side of the second annular table surface facing the outer end surface of the housing of the earphone core, and elastically abuts the housing of the earphone core when the housing of the earphone core is fixed with the plug end.

13. The loudspeaker apparatus of claim 12 , wherein the protective sleeve forms an annular abutting surface on a side of the second annular table surface facing the outer end surface of the housing of the earphone core, and an annular boss located inside the annular abutting surface and protruding from the annular abutting surface; and
the housing of the earphone core includes an inclined surface for connecting the outer end surface of the housing of the earphone core and the inner sidewall of the socket hole;
wherein when the housing of the earphone core is fixedly connected to the plug end, the annular abutting surface and the annular boss abut elastically the outer end surface of the housing of the earphone core and the inclined surface, respectively.

14. The loudspeaker apparatus of claim 1 , wherein the hinge component comprises a hinge, a rod-like component, and a fixing component;
the hinge comprising:
a hinge base; and
a hinge arm, wherein the hinge arm is rotatably connected to the hinge base through a rotation shaft, and when an external force is applied to the hinge arm, the hinge arm is capable of rotating relative to the hinge base to change a position of a loudspeaker component relative to the ear hook.

15. The loudspeaker apparatus of claim 1 , wherein an inner surface of the housing of the earphone core is disposed with a first recessed area, and the housing of the earphone core is disposed with a keyhole located in the first recessed area and used to connect the inner surface and an outer surface of the housing of the earphone core.
