Abstract

The embodiments of present disclosure disclose a loudspeaker. The loudspeaker may include an ear hook including a first plug end and a second plug end. The ear hook may be surrounded by a protection sleeve, and the protection sleeve may be made of an elastic waterproof material. The loudspeaker may include an earphone core housing configured to accommodate the earphone core, and the earphone core housing may be fixed to the first plug end through plugging, and may be elastically abutted against the protection sleeve elastically. The loudspeaker may include a circuit housing configured to accommodate a control circuit or a battery. The circuit housing may be fixed to the second plug end through plugging.

First claim

What is claimed is:

1. A loudspeaker, comprising:
an ear hook, including a first plug end and a second plug end, the ear hook being surrounded by a protection sleeve, the protection sleeve being made of an elastic waterproof material;
an earphone core housing configured to accommodate an earphone core, the earphone core housing being fixed to the first plug end through plugging, wherein when a user wears the loudspeaker, the ear hook is configured to support the earphone core housing at a position of the user's head without blocking the user's ear canal; and
a circuit housing configured to accommodate a control circuit or a battery, the circuit housing being fixed to the second plug end through plugging, and the control circuit or the battery driving the earphone core to vibrate to generate sound.

2. The loudspeaker of claim 1 , wherein the ear hook further comprises:
an elastic metal wire;
a lead wire and a fixing sleeve, wherein the fixing sleeve fixes the lead wire to the elastic metal wire; and
the protection sleeve being formed on a periphery of the elastic metal wire, the lead wire, the fixing sleeve, the first plug end, and the second plug end by injection molding.

3. The loudspeaker of claim 2 , wherein the first plug end and the second plug end are formed at two ends of the elastic metal wire by injection molding, respectively, a first cable-routing channel and a second cable-routing channel are set on the first plug end and the second plug end, respectively, and the lead wire extends along the first cable-routing channel and the second cable-routing channel.

4. The loudspeaker of claim 3 , wherein the lead wire is set in the first cable-routing channel and the second cable-routing channel in a threading manner.

5. The loudspeaker of claim 2 , wherein there are at least two fixing sleeves, and the fixing sleeves are spaced at intervals along the elastic wire.

6. The loudspeaker of claim 1 , wherein a first plug hole is set on the earphone core housing connecting the outer end surface of the earphone core housing, a stop block is set on an inner side wall of the first plug hole, and the first plug hole is connected to the first plug end through clamping.

7. The loudspeaker of claim 6 , wherein,
the first plug end includes an insertion portion and two elastic hooks;
the insertion portion is at least partially inserted into the first plug hole, and abuts against an outer surface of the stop block;
the two elastic hooks are disposed on a side of the insertion portion facing the inside of the earphone core housing, the two elastic hooks are brought close to each other under an action of an external thrust and the stop block, and elastically restored to be stuck on the inside surface of the stop block after passing through the stop block, fixing the first plug end to the earphone core housing through plugging.

8. The loudspeaker of claim 7 , wherein the insertion portion is partially inserted into the first plug hole, and an exposed portion of the insertion portion has a stair-step shape, forming an annular platform spaced at intervals from the outer end surface of the earphone core housing.

9. The loudspeaker of claim 8 , wherein the protection sleeve further extends to a side of the annular platform facing the outer end surface of the earphone core housing, and elastically abuts against the earphone core housing for sealing when the earphone core housing is fixed to the first plug end through plugging.

10. The loudspeaker of claim 1 , wherein the loudspeaker further includes a fixing member; a second plug hole is set on the circuit housing, and the second plug end is at least partially inserted into the second plug hole and connects the second plug hole through the fixing member.

11. The loudspeaker of claim 10 , wherein,
the second plug end includes a groove being perpendicular to the insertion direction of the second plug hole, and a through hole corresponding to a position of the groove is set on a first side wall of the circuit housing;
the fixing member includes two pins disposed in parallel and a connecting portion for connecting the pins; and the pins are inserted into the groove from the outside of the circuit housing through the through hole, realizing the fixing of the circuit housing and the second plug end through plugging.

12. The loudspeaker of claim 1 , wherein the ear hook further includes a housing protector integrally formed with the protection sleeve, and the housing protector is cladded on a periphery of the circuit housing in a sleeved manner.

13. The loudspeaker of claim 1 , wherein the earphone core includes at least a composite vibration apparatus including a vibration board and a second vibration conducting sheet, and the composite vibration apparatus generates the two resonance peaks.

14. The loudspeaker of claim 13 , wherein the earphone core further includes at least one voice coil and at least one magnetic circuit system; the voice coil is physically connected to the vibration board, and the magnetic circuit system is physically connected to the second vibration conducting sheet.

15. The loudspeaker of claim 13 , wherein a stiffness coefficient of the vibration board is greater than a stiffness coefficient of the second vibration conducting sheet.

16. The loudspeaker of claim 13 , wherein, the earphone core further includes a first vibration conducting sheet;
the first vibration conducting sheet is physically connected to the composite vibration apparatus;
the first vibration conducting sheet is physically connected to the earphone core housing; and
the first vibration conducting sheet generates another resonance peak.

17. The loudspeaker of claim 16 , wherein both the two resonance peaks are within a frequency range audible to a human ear.

18. The loudspeaker of claim 13 , wherein the earphone core housing further includes at least one contact surface, and the contact surface is at least partially in direct or indirect contact with a user; and
the contact surface has a gradient structure, distributing pressure on the contact surface unevenly.

19. The loudspeaker of claim 18 , wherein the gradient structure includes at least one convex or at least one groove, and is located at a center or an edge of the contact surface.

20. The loudspeaker of claim 13 , wherein the earphone core housing further includes at least one contact surface, and the contact surface is at least partially in direct or indirect contact with a user;
the contact surface includes at least a first contact surface region and a second contact surface region, and the degree of convexity of the second contact surface region is greater than the degree of convexity of the first contact surface region.
