Abstract

A speaker device is provided. The speaker device may include a circuit housing, an ear hook, a rear hook, and a speaker assembly. The circuit housing may be configured to accommodate a control circuit or a battery. The ear hook may be connected to one end of the circuit housing and at least a part of the ear hook being covered by a first housing sheath. The rear hook may be connected to the other end of the circuit housing and at least a part of the rear hook being covered by a second housing sheath. The first housing sheath and the second housing sheath may cover at least a part of a periphery of the circuit housing from two ends of the circuit housing, respectively. The speaker assembly may include an earphone core and a core housing for accommodating the earphone core.

First claim

What is claimed is:

1. A speaker device, comprising:
a speaker assembly, the speaker assembly including an earphone core and a core housing for accommodating the earphone core, and a location of the speaker assembly relative to an ear hook being able to change, so that the speaker assembly being attached to a front side or a rear side of a user's ear.

2. The speaker device of claim 1 , wherein the speaker device further includes a circuit housing, wherein
the circuit housing is configured to accommodate a control circuit or a battery,
the ear hook and the speaker assembly are connected to opposite ends of the circuit housing, respectively.

3. The speaker device of claim 2 , wherein the speaker device further includes a rear hook, wherein
at least a part of the ear hook is covered by a first housing sheath, and
the rear hook is connected to the other end of the circuit housing away from the ear hook and at least a part of the rear hook being covered by a second housing sheath, the first housing sheath and the second housing sheath covering at least a part of a periphery of the circuit housing from two ends of the circuit housing, respectively.

4. The speaker device of claim 3 , wherein the circuit housing comprises one or more main side walls, one or more auxiliary side walls, and one or more end walls connected with each other, wherein the first housing sheath and the second housing sheath is coupled to each other on the one or more main side walls and the one or more auxiliary side walls.

5. The speaker device of claim 4 , wherein an inner surface of the first housing sheath or the second housing sheath corresponding to the one or more main side walls includes a positioning convex block, and an outer surface of the one or more main side walls is provided with a positioning groove corresponding to the positioning convex block.

6. The speaker device of claim 4 , wherein coupled regions between the first housing sheath and the second housing sheath on the one or more main side walls and the one or more auxiliary sides wall are arranged obliquely with respect to the one or more auxiliary side walls.

7. The speaker device of claim 4 , wherein
the rear hook includes a plug end facing an end of the circuit housing, and the second housing sheath is sleeved on a periphery of at least a part of the plug end;
the circuit housing includes a socket facing the rear hook, and the plug end is at least partially inserted into the socket; wherein slots perpendicular to an insertion direction of the plug end relative to the socket are located on the plug end, and a first side wall of the socket is provided with a first through-hole corresponding to positions of the slots; and
the speaker device further includes a fixing component, the fixing component including two pins disposed in parallel and a connecting part for connecting the pins; wherein the pins are inserted into the slots through the first through-hole from an outer side wall of the first side wall of the socket so as to achieve a plugged-in connection between the circuit housing and the rear hook.

8. The speaker device of claim 3 , wherein a cover area of one of the first housing sheath or the second housing sheath on the circuit housing is not less than a half of a cover area of the other one of the first housing sheath or the second housing sheath on the circuit housing.

9. The speaker device of claim 1 , wherein the speaker assembly is connected to an end of the ear hook through a hinge assembly, and the hinge assembly is able to rotate to change the location of the speaker assembly relative to the ear hook.

10. The speaker device of claim 9 , wherein the hinge assembly comprises a hinge, a rod-like component, and a fixing component; the hinge includes:
a hinge base; and
a hinge arm, wherein the hinge arm and the hinge base are rotatably connected by a rotating axis, and the hinge arm rotates relative to the hinge base under an external force, so as to alter a position of the speaker assembly relative to the ear hook;
a supporting element, the supporting element being movably arranged on the hinge base; and
an elastic element, the elastic element is configured to elastically bias the supporting element toward the hinge arm so that the supporting element elastically abuts against the hinge arm.

11. The speaker device of claim 10 , wherein
the hinge arm includes a first supporting surface and a second supporting surface connected with each other;
the support element includes a third supporting surface;
the third supporting surface elastically abuts against the first supporting surface and the second supporting surface, respectively, when the supporting element is elastically biased toward the hinge arm; and
the supporting element is driven to rotate reversely to overcome the elastic bias of the elastic element by a connection between the first supporting surface and the second supporting surface when the hinge arm rotates relative to the hinge base under an external force, so that the third supporting surface is switched from elastically abutting against one of the first supporting surface or the second supporting surface to the other one of the first supporting surface or the second supporting surface.

12. The speaker device of claim 11 , wherein
the hinge base includes a base body, a first lug, and a second lug, and the first lug and the second lug protrude from the base body and are arranged at intervals between each other; and
the hinge arm includes an arm body and a third lug protruding from the arm body, and the third lug is inserted into an interval region between the first lug and the second lug and is rotatably connected with the first lug and the second lug through the rotating axis.

13. The speaker device of claim 12 , wherein
the supporting element is at least partially arranged in the interval region and located on one side of the third lug facing the base body; and
the base body is provided with an accommodating cavity communicated with the interval region, the elastic element is disposed within the accommodating cavity, and the supporting element is elastically biased toward the third lug by the elastic element.

14. The speaker device of claim 1 , wherein the earphone core at least includes a composite vibration assembly constituted by a vibration plate and a second vibration conductive plate, the composite vibration assembly generating two resonance peaks.

15. The speaker device of claim 14 , wherein
the earphone core further includes at least one voice coil and at least one magnetic circuit assembly; and
