Abstract

Disclosed is an earphone, including an earbud structure and an earphone handle; the earphone handle is rotatably connected to the earbud structure to adjust a wearing posture of the earphone handle. The main objective of the present application is to provide an earphone that can adjust the wearing posture of the earphone handle, thereby improving the user's wearing comfort.

First claim

What is claimed is:

1 . An earphone, comprising:
an earbud structure; and an earphone handle rotatably connected to the earbud structure to adjust a wearing posture of the earphone handle; wherein one of the earphone handle and the earbud structure is provided with a rotating portion, and the other of the earphone handle and the earbud structure is provided with a rotating groove, and the rotating portion is rotatably provided in the rotating groove, so that the earphone handle is rotatably connected to the earbud structure, one end of the earphone handle is provided with the rotating portion, and the earbud structure is provided with the rotating groove, a plane where a notch of the rotating groove is located is defined as a reference plane, and an axis of the earphone handle is configured to extend along an extension direction of the earphone handle, and in response to that the earphone handle rotates relative to the earbud structure, an angle between the axis of the earphone handle and the reference plane is θ1, and 0≤θ1≤45°.

2 . The earphone of claim 1 , wherein the rotating portion is provided with a shaft hole, the earbud structure is provided with an abutting shaft at least partially in the rotating groove, and the abutting shaft is rotatably provided in the shaft hole.

3 . The earphone of claim 2 , wherein the earbud structure is further provided with a fixed chamber and a sliding port, and the fixed chamber is communicated with the rotating groove through the sliding port; and
the abutting shaft comprises an elastic member and a connector, one end of the elastic member is connected to a wall of the fixed chamber, the other end of the elastic member is connected to one end of the connector, and the other end of the connector is configured to extend into the rotating groove through the sliding port and is rotatably provided in the shaft hole.

4 . The earphone of claim 2 , wherein the rotating portion is further provided with a first convex arc surface, and a wall of the rotating groove is formed with a first concave arc surface matched with the first convex arc surface; and/or
the earphone handle is provided with a battery, the rotating portion is provided with a conductive column electrically connected to the battery, and the conductive column is provided with a contacting piece corresponding to the shaft hole; the earbud structure is provided with a circuit board, the abutting shaft is electrically connected to the circuit board, and the abutting shaft is rotatably provided in the shaft hole and is abutted against the contacting piece.

5 . The earphone of claim 1 , wherein the rotating portion is a spherical convex portion, and the rotating groove is a spherical concave groove matched with the spherical convex portion.

6 . The earphone of claim 5 , wherein the rotating portion is provided with a clamping groove, the earbud structure is further provided with a connecting member at least partially in the rotating groove, and the connecting member is movably clamped in the clamping groove.

7 . The earphone of claim 6 , wherein two connecting members are provided, the two connecting members are symmetrical and along the extension direction of the earphone handle, and the rotating portion is provided with the clamping groove corresponding to the connecting member.

8 . The earphone of claim 6 , wherein the earbud structure is also provided with a cavity and a circuit board located in the cavity, the wall of the rotating groove is provided with a via hole communicated with the cavity, and one end of the connecting member is configured to extend into the cavity through the via hole and is electrically connected to the circuit board;
the earphone handle is provided with the battery, the rotating portion is provided with a conductive column electrically connected to the battery, and the conductive column is provided with the contacting piece corresponding to the clamping groove; and the connecting member is movably clamped in the clamping groove and is abutted against the contacting piece.

9 . The earphone of claim 8 , wherein one end of the connecting member located in the rotating groove is provided with a second convex arc surface, and the contacting piece is provided with a second concave arc surface matched with the second convex arc surface.

10 . The earphone of claim 6 , wherein the earbud structure comprises:
an earbud shell, wherein the earbud shell is provided with the cavity and an opening communicated with the cavity; and a rotating shell, wherein the rotating shell is provided with the rotating groove, the rotating shell is movably provided in the cavity, the notch of the rotating groove is directly communicated with the opening, and the connecting member is connected to the rotating shell.

11 . The earphone of claim 10 , wherein the earbud shell is provided with a sliding groove adjacent to the opening, the rotating shell is provided with a slider adjacent to the notch of the rotating groove, and the slider is slidably provided in the sliding groove, so that the rotating shell is rotatably connected to the earbud shell.

12 . The earphone of claim 11 , wherein the earbud shell is provided with two sliding grooves, the two sliding grooves are symmetrical, the rotating shell is provided with two sliders, and the sliders are slidably provided in the sliding groove;
a connection line between the two sliders and a connection line between the two connecting members are at an angle, and the connection line of the two connecting members is defined as a reference line; and in response to that the rotating shell rotates relative to the earbud shell, an angle between the axis of the earphone handle and the reference line is θ2, and 0≤θ2≤45°.

13 . The earphone of claim 1 , wherein the earbud structure is provided with a first magnetic member, and the earphone handle is provided with a second magnetic member magnetically connected to the first magnetic member.
