Abstract

The present disclosure relates to an apparatus. The apparatus may comprise two ear-hook assemblies configured to be hung outside of two ears of a user respectively, and a rear-hook assembly in a curved shape configured to connect the two ear-hook assemblies and wrap around a rear side of the head of the user. The rear-hook assembly may include an elastic metal filament, wires, and an elastic covering body covering the elastic metal filament and the wires.

First claim

What is claimed is:

1. An apparatus, comprising:
two ear-hook assemblies, configured to be hung outside of two ears of a user respectively; and
a rear-hook assembly in a curved shape, configured to connect the two ear-hook assemblies and wrap around a rear side of the head of the user, the rear-hook assembly including an elastic metal filament, wires, and an elastic covering body covering the elastic metal filament and the wires, wherein the elastic covering body and the wires are an extruded integral structural member, the elastic covering body further forms a threaded channel, the elastic metal filament is threaded in the threaded channel, and a diameter of the threaded channel in a natural state is less than a diameter of the elastic metal filament, so that the elastic metal filament is fixed with the elastic covering body after being inserted into the threaded channel.

2. The apparatus of claim 1 , wherein
a count of the wires is at least two strands, each strand of the wires includes a metal wire and an insulation layer covering the metal wire, and the insulation layer is configured to realize electrical insulation between metal wires.

3. The apparatus of claim 1 , further comprising two core modules, wherein one end of each ear-hook assembly is connected to one of the two core modules, and two ends of the rear-hook assembly are respectively connected to the other end of each ear-hook assembly away from a core module of the two core modules.

4. The apparatus of claim 3 , wherein a core module of the two core modules includes a core housing and a core, one end of the core housing includes an opening, and the core is within the core housing.

5. The apparatus of claim 4 , wherein an ear-hook assembly of the two ear-hook assemblies includes an ear-hook housing, the ear-hook housing includes an accommodation bin, a bending transition portion, and an earphone fixing portion, the accommodation bin is connected to the rear-hook assembly and is configured to accommodate a battery assembly or a control circuit assembly, and the earphone fixing portion is arranged on an opening end of the core housing to form a chamber structure for accommodating the core, and the bending transition portion is arranged in a bending shape and is connected to the accommodation bin and the earphone fixing portion to be hung outside an ear of the user.

6. The apparatus of claim 5 , wherein
an elastic modulus of the core housing is greater than that of the ear-hook housing, the earphone fixing portion is provided with a reinforcing structure, and a ratio of a difference between a stiffness of a skin contact area of the core housing and a stiffness of the earphone fixing portion to the stiffness of the skin contact area of the core housing is less than or equal to 10%; and
the reinforcing structure is configured to increase the stiffness of the earphone fixing portion to reduce a difference between the stiffness of the earphone fixing portion and the stiffness of the core housing.

7. The apparatus of claim 5 , wherein the core module further includes a cover plate, the cover plate is arranged on the opening end of the core housing to form the chamber structure for accommodating the core, the earphone fixing portion is arranged on a side of the cover plate away from the core housing, wherein an elastic modulus of the core housing is greater than that of the ear-hook housing, and an elastic modulus of the cover plate is greater than that of the ear-hook housing.

8. The apparatus of claim 5 , wherein the ear-hook assembly further includes a decoration member, the decoration member includes a decoration bracket, the ear-hook housing is at least provided with a first groove on the bending transition portion, and the decoration bracket is embedded and fixed in the first groove of the bending transition portion to form a wiring channel, the wiring channel allows the wires to extend from the core module to the accommodation bin through the wiring channel.

9. The apparatus of claim 1 , wherein the rear-hook assembly further includes inserting portions arranged at two ends of the elastic metal filament, the inserting portions are configured to connect and match with the ear-hook assembly, at least one inserting portion is provided with two groups of notches at intervals in a length direction, one group of notches is configured to clamp and match with the ear-hook assembly, and the other group of notches is configured to mold position.

10. The apparatus of claim 9 , wherein each group of notches includes two notches arranged opposite to each other, and the two notches extend from edges of the at least one inserting portion to a central axis, wherein the edges are on two sides of the central axis.

11. The apparatus of claim 9 , wherein the ear-hook assembly includes a first ear-hook housing and a second ear-hook housing, the first ear-hook housing and the second ear-hook housing are cooperatively connected to form an accommodating space for accommodating the battery assembly or the control circuit assembly, one side of the first ear-hook housing is provided with a plug-in hole connecting the accommodating space, the at least one inserting portion is inserted into the plug-in hole, and a snap portion protruding from the first ear-hook housing is embedded in a notch at one end away from the at least one inserting portion.

12. The apparatus of claim 11 , wherein splicing edges of the first ear-hook housing and the second ear-hook housing fit with each other, the first ear-hook housing is spaced to form a first slot and a second slot with a same opening direction, the second ear-hook housing is protruding provided with a first block and a second block with a same extending direction, the first block and the second block are respectively embedded into the first slot and the second slot along a same direction to limit a relative movement of the first ear-hook housing and the second ear-hook housing in different directions.

13. The apparatus of claim 12 , wherein
the first slot and the second slot are respectively located on two sides of the first ear-hook housing along the length direction, an opening direction of the first slot faces the accommodating space, and an opening direction of the second slot deviates from the accommodating space; and
the first block and the second block are respectively located on two sides of the second ear-hook housing along the length direction, an extending direction of the first block deviates from the accommodating space, and an extending direction of the second block faces the accommodating space.

14. The apparatus of claim 13 , wherein a splicing edge of the first ear-hook housing is provided with a first blocking portion, a splicing edge of the second ear-hook housing is provided with a second blocking portion, and the first blocking portion and the second blocking portion fit with each other to limit a relative movement of the first ear-hook housing and the second ear-hook housing in the length direction.
