Abstract

One or more embodiments of the present disclosure relate to an earphone, the earphone comprises: a speaker assembly configured to contact with a human head and transmit sound; a function assembly electrically connected to the speaker assembly and configured to control the speaker assembly; and an ear hook connected between the speaker assembly and the function assembly, wherein an attitude or position of the speaker assembly or the function assembly is adjustable with respect to the ear hook.

Claims (23)

1 . An earphone, comprising:

a speaker assembly configured to contact with a human head and transmit sound;

a function assembly electrically connected to the speaker assembly and configured to control the speaker assembly; and

an ear hook connected between the speaker assembly and the function assembly, so that a preset angle is formed between a first surface of the speaker assembly toward the human head and a second surface of the function assembly toward the human head, and a force generated by a contact between the first surface and the human head is greater than or equal to 0.1 N and less than or equal to 4.5 N, wherein an attitude or position of the speaker assembly or the function assembly is adjustable with respect to the ear hook, and the preset angle is in a range of 5 degrees to 10 degrees.

2 . The earphone of claim 1 , wherein the first surface includes a curved surface that is outwardly convex.

3 . The earphone of claim 1 , wherein the function assembly is provided with a chamfered corner adjacent to a back side of a human ear.

4 . The earphone of claim 1 , wherein the function assembly is flexibly connected to the ear hook, and the function assembly follows a deflection when the function assembly is touched by an external force.

5 . The earphone of claim 4 , wherein the function assembly is provided with a turning hole, and one end of the ear hook is rotatably connected to the turning hole.

6 . The earphone of claim 4 , wherein in a state where the function assembly is not in contact with the human head and a human ear, a surface of the function assembly toward the human head is in a first position; in a state where the function assembly is worn, a surface of the function assembly toward the human head is in a second position, wherein a deflection angle between the surfaces of the function assembly at the first position and the second position toward the human head is within a range of 0 degrees to a preset threshold angle.

7 . The earphone of claim 6 , wherein a value of the preset threshold angle is in a range of 10 degrees to 20 degrees.

8 . The earphone of claim 6 , wherein the function assembly is deflected toward a side close to the human head and/or deflected toward a side away from the human head.

9 . The earphone of claim 1 , wherein the speaker assembly is adjustable in attitude with respect to the ear hook.

10 . The earphone of claim 9 , wherein a side of the speaker assembly away from the human head is flexibly connected to one end of the ear hook.

11 . The earphone of claim 9 , wherein a side edge of the speaker assembly toward the human head is provided with an adhesive layer, the adhesive layer being configured to affix to the human head.

12 . The earphone of claim 9 , wherein a side edge of the speaker assembly toward the human head is provided with an anti-slip member.

13 . The earphone of claim 1 , wherein the speaker assembly, the function assembly, and the ear hook are provided in two groups correspondingly located on left and right sides of the human head, and the earphone further includes:

a rear hook connected between two groups of the function assemblies or two groups of the ear hooks, a position of the rear hook being adjustable with respect to the function assemblies.

14 . The earphone of claim 13 , wherein the function assembly is in a form of a block, one end of the ear hook is connected to a width side edge of the function assembly, and the rear hook is flexibly connected between two groups of the ear hooks, wherein a total mass of the speaker assembly is greater than a total mass of the function assembly and the rear hook.

15 . The earphone of claim 14 , wherein, in a worn state, the ear hook is supported on a human ear and a torque generated by the two groups of the speaker assemblies is balanced with a torque generated by the two groups of the functional assemblies and the rear hooks.

16 . The earphone of claim 15 , wherein a torque generated from the two groups of the speaker assembly to support points of the ear hooks on the human ear is balanced with a torque generated from the two groups of the function assemblies and the rear hooks to the support points of the ear hooks on the human ear.

17 . The earphone of claim 13 , wherein the rear hook is connected between two groups of the ear hooks, and in the worn state, the rear hook is supported on a top of the human head, the rear hook including a first headwear portion and two second headwear portions, one end of each of the two second headwear portions being rotatably connected to one end of the first headwear portion, and the second headwear portions being further connected to the ear hooks; wherein in the worn state, the second headwear portions are rotatable in a vertical direction with respect to the first headwear portion.

18 . The earphone of claim 13 , wherein the function assembly is connected to one end of the ear hook and is provided in a streamlined shape with the ear hook, and each of two ends of the rear hook is connected to an end of the corresponding function assembly away from the ear hook and the ear hook is provided in a streamlined shape with the function assembly.

19 . The earphone of claim 18 , wherein the rear hook includes a metal body, the metal body being electrically connected to the function assembly to act as an antenna for the earphone.
