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.

Claims (30)

1 . A loudspeaker apparatus, comprising:

an ear hook including an elastic metal wire, a wire, and a plug end disposed at one end of the elastic metal wire;

a housing of an earphone core configured to accommodate the earphone core; and

a circuit housing configured to accommodate a circuit component or a battery, wherein

the plug end is fixed plugged with the housing of the earphone core or the circuit housing,

the plug end is disposed with a trace channel, and

the wire passes through the trace channel, wherein the trace channel includes a trace slot, and the wire at the plug end extends along the trace slot.

2 . The loudspeaker apparatus of claim 1 , wherein the trace channel includes a trace hole connected to the trace slot, and the wire at the plug end extends along the trace slot and the trace hole and is exposed on an outer end surface of the plug end.

3 . The loudspeaker apparatus of claim 2 , wherein the trace slot connects to the outer end surface of the plug end.

4 . The loudspeaker apparatus of claim 2 , wherein the plug end is fixed plugged with the housing of the earphone core, and a joint position of the trace slot and the trace hole is located outside of the housing of the earphone core.

5 . The loudspeaker apparatus of claim 2 , wherein the plug end is fixed plugged with the circuit housing, and a joint position of the trace slot and the trace hole is located outside of the circuit housing.

6 . The loudspeaker apparatus of claim 2 , wherein the ear hook further includes a protective sleeve disposed on a periphery of the elastic metal wire, the wire, and the plug end, wherein the protective sleeve covers the trace slot, and an end of the plug end away from the elastic metal wire is exposed from the protective sleeve.

7 . The loudspeaker apparatus of claim 6 , wherein the protective sleeve is injection-molded on the periphery of the elastic metal wire and the plug end.

8 . The loudspeaker apparatus of claim 6 , wherein the ear hook further includes at least two fixed sleeves configured to fix the wire on the elastic metal wire, and the at least two fixed sleeves are arranged at interval along an extension direction of the elastic metal wire and the wire.

9 . The loudspeaker apparatus of claim 6 , wherein the ear hook further includes a housing protector, wherein the housing protector at least partially covers a periphery of the circuit housing.

10 . The loudspeaker apparatus of claim 9 , wherein the housing protector and the protective sleeve are integrally formed.

11 . The loudspeaker apparatus of claim 9 , wherein the housing protector includes a bag 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.

12 . The loudspeaker apparatus of claim 9 , wherein a shape of an inner wall of the housing protector matches a shape of an outer wall of the circuit housing.

13 . The loudspeaker apparatus of claim 1 , wherein the plug end includes a first plug end and a second plug end disposed at two ends of the elastic metal wire.

14 . The loudspeaker apparatus of claim 13 , wherein the trace channel includes a first trace channel and a second trace channel respectively disposed on the first plug end and the second plug end, and the wire extends along the first trace channel and the second trace channel.

15 . The loudspeaker apparatus of claim 13 , wherein the first plug end and the second plug end are fixed plugged with the housing of the earphone core and the circuit housing, respectively.

16 . The loudspeaker apparatus of claim 1 , wherein the plug end is formed at the end of the elastic metal wire by injection-molding.

17 . The loudspeaker apparatus of claim 1 , wherein

the plug end includes an insertion portion,

the housing of the earphone core is disposed with a socket hole communicating with an outer end surface of the housing of the earphone core, and

the insertion portion is at least partially inserted into the socket hole.

18 . The loudspeaker apparatus of claim 17 , wherein the insertion portion includes an exposed portion exposed to the housing of the earphone core, and the exposed portion is a stair-step shape.

19 . The loudspeaker apparatus of claim 1 , wherein the housing of the earphone core is connected to an 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.

20 . The loudspeaker apparatus of claim 1 , wherein

the ear hook further includes a protective sleeve disposed on a periphery of the elastic metal wire, the wire, and the plug end.
