The specific structure of the earphone according to the embodiment of the present application is described below with reference to fig. 1 to 9.

According to some embodiments of the present application, as shown in fig. 1 and 2, the earphone includes an earphone housing 10, a telescopic rod 211, an electromagnetic member, a magnetic member 22, and a clip member 24. The earphone shell 10 is provided with a through hole 11, and the telescopic rod 211 is movably inserted into the through hole 11. As shown in fig. 3, a first end of the telescopic rod 211 is provided with a buckling part 212. The second end of the telescopic rod 211 can extend out of the earphone housing 10 from the through hole 11 or retract into the earphone housing 10. As shown in fig. 4, the clip 24 is slidably coupled to the earphone housing 10. One of the earphone case 10 and the clip 24 is provided with a magnetic member 22, and the other is provided with an electromagnetic member, which is disposed opposite to the magnetic member 22.

Under the condition that the clamping piece 24 is in the first state relative to the earphone shell 10, the buckling part 212 is clamped at the first position of the clamping piece 24, and the telescopic rod 211 is located in the earphone shell 10. Under the driving of the electromagnetic element, the clamping element 24 slides relative to the earphone shell 10, and the clamping element 24 drives the telescopic rod 211 to move. Under the condition that the clamping piece 24 slides to the second state relative to the earphone shell 10, the telescopic rod 211 extends out of the earphone shell 10. Wherein, along with the sliding of the clip 24 relative to the earphone shell 10, the clip 24 is switched between the first state and the second state relative to the earphone shell 10.

In an embodiment of the present application, when the clip 24 is in the second state relative to the earphone shell 10, the clip portion 212 is clipped at the second position of the clip 24. In another embodiment of the present invention, the fastening portion 212 is abutted against the abutting surface of the fastening member 24, so as to limit the position of the telescopic rod 211 relative to the through hole 11 by the abutting surface.

In an embodiment of the present application, when the electromagnetic element is powered on, the telescopic rod 211 extends out of the earphone shell 10; when the electromagnetic element is powered off, the telescopic rod 211 is reset and is positioned in the earphone shell 10. Specifically, when the earphone is in the non-wearing state, the electromagnetic element is powered off, as shown in fig. 6 and 8, the telescopic rod 211 is inside the earphone shell 10, that is, the telescopic rod 211 is in the retracted state, and the fastening portion 212 is located at the first position of the fastening member 24. When the earphone is worn, the electromagnetic element is energized, the magnetic element 22 is attracted by the electromagnetic element, as shown in fig. 7 and 9, the telescopic rod 211 extends outward under the action of the magnetic force between the electromagnetic element and the magnetic element 22, at this time, the telescopic rod 211 is in an outward extending state, and the buckling part 212 moves to the second position of the clamping element 24. In another embodiment of the present application, the extension or retraction state of the telescopic rod 211 is changed by adjusting the power-on direction of the electromagnetic member.

It should be noted that, when the telescopic rod 211 is in the extended state, the second end of the telescopic rod 211 extends out of the earphone shell 10 or slightly extends out of the earphone shell 10; when the telescopic rod 211 is in the retracted state, the second end of the telescopic rod 211 is retracted into the through hole 11 and is flush with the outer wall of the earphone shell 10 or the second end is located in the through hole 11.

According to alternative embodiments of the present application, the telescopic rod 211 is inserted and fixed on the fastening part 212 or the telescopic rod 211 and the fastening part 212 are an integral structure. It can be understood that the installation position of the electromagnetic element is matched with the magnetic element 22, as long as the electromagnetic element is electrified, and the attraction force between the electromagnetic element and the magnetic element can drive the telescopic rod 211 to move telescopically along the through hole 11.

The on/off or current direction of the electromagnetic member is determined based on the wearing state of the earphone. The wearing state of the earphone is judged according to learning collected by the pressure sensor when the earphone is inserted into the ear hole, or on-off signals or other using state signals of the earphone. Taking power on and off as an example, in a wearing state, the earphone is mostly in a using state of answering a call, enjoying music and the like. The answering signal can be a telephone answering signal and/or a music playing signal, and correspondingly, the hang-up signal is a telephone disconnecting signal and/or a music stopping signal. According to further embodiments of the present application, the electromagnet is powered on based on a power-on signal and powered off based on a power-off signal. For example, the earphone is provided with a power-on/off key, when the power-on/off key is pressed to start, a power-on signal is generated, and the electromagnetic element is electrified according to the power-on signal; when the power-on/off button is pressed again to turn off the earphone, a power-off signal is generated, and the electromagnetic piece is powered off according to the power-off signal. According to some embodiments of the present application, the electromagnetic element is powered on and off based on signals generated when other keys except the power on/off key are pressed, and the control process is similar to the pressing of the power on/off key, which is not described again. The reverse change process of the current direction is similar to the switching process of the power-on and power-off, and is not described in detail.

In some embodiments of the present application, the clamping member 24 is provided with a chute 12, and a wall of the chute 12 is inclined with respect to the telescopic direction of the telescopic rod 211. The locking portion 212 is a slider that can slide along the chute 12. Under the condition that the clamping piece 24 is in the second state relative to the earphone shell 10, the sliding block is clamped at the second position of the clamping piece 24. The distance between the second position and the earphone shell in the extension direction of the telescopic rod is smaller than the distance between the first position and the earphone shell in the extension direction of the telescopic rod. This embodiment provides a headset where the second position and the first position may both be in the chute 12 or may be two snap positions in communication with the chute 12.

Specifically, as shown in fig. 5, after the electromagnetic element is powered on, the magnetic element 22 is attracted by the electromagnetic element to drive the clamping element 24 to slide relative to the earphone shell 10, and since the extending direction of the slot wall of the chute 12 is inclined relative to the extending direction of the telescopic rod 211, the slot wall of the chute 12 pushes the buckling part 212 when the clamping element 24 moves, so as to drive the telescopic rod 211 to move in the through hole 11.

In some embodiments, the extending and retracting direction of the telescopic rod 211 is perpendicular to the sliding direction of the clamping member 24, that is, the extending direction of the insertion hole 13 is perpendicular to the extending and retracting direction of the telescopic rod 211, and the extending direction of the inclined groove 12 is inclined relative to the extending and retracting direction of the telescopic rod 211, so as to reduce the transverse width occupied by the telescopic rod 211 and the clamping member 24 after being assembled to the maximum extent.

Regarding the installation positions of the electromagnetic element and the magnetic element 22, the embodiment of the present application is not particularly limited, as long as after the electromagnetic element is powered on, the attraction force between the magnetic element 22 and the electromagnetic element can drive the sliding rod 241 to move along the insertion hole 13.

The earphone that this application embodiment provided, with the help of joint spare 24 with the slip of joint spare 24 change the flexible of telescopic link 211 into to reduce the horizontal width after telescopic link 211 and the equipment of joint spare 24, make it to install in narrower space.

Specifically, the clamping member 24 includes a sliding rod 241 and a connecting head 242, and the connecting head 242 is fixedly installed at one end of the sliding rod 241. The earphone case 10 is provided with a jack 13, and the sliding bar 241 is slidably mounted in the jack 13. Wherein, the electromagnetic element and the magnetic element 22 cooperate with each other to drive the sliding rod 241 to move in the insertion hole 13 when the electromagnetic element is powered on. The chute 12 is provided on the connecting head 242. The sliding rod 241 and the connecting head 242 are integrated or fixedly connected.

As shown in fig. 4, the magnetic member 22 is installed at one end of the connection head 242 away from the sliding rod 241, the sliding direction of the sliding rod 241 is perpendicular to the telescopic direction of the telescopic rod 211, and an included angle formed by the extending direction of the inclined slot 12 and the telescopic direction of the telescopic rod 211 is an obtuse angle. Correspondingly, the electromagnetic element is installed on the inner wall of the earphone shell 10 and opposite to the magnetic element 22.

When the earphone is worn, the electromagnetic element is energized to attract the magnetic element 22, and further the sliding rod 241 is driven to move upwards in the jack 13. Since the extending direction of the inclined groove 12 and the extending and retracting direction of the telescopic rod 211 form an obtuse angle, the first position of the inclined groove 12 is farther away from the inner wall region of the earphone housing 10 where the through hole 11 is provided relative to the second position of the inclined groove 12, and in the process that the buckling part 212 moves from the first position to the second position of the inclined groove 12, as shown in fig. 7, the telescopic rod 211 is pushed outwards by the groove wall of the inclined groove 12 along with the buckling part 212. In the earphone provided by the embodiment, the sliding direction of the sliding rod 241 is perpendicular to the telescopic direction of the telescopic rod 211, so that the transverse space occupied by the telescopic rod 211 and the clamping piece 24 after assembly can be reduced to the greatest extent; the magnetic member 22 is installed at one end of the connecting head 242 away from the sliding rod 241, an included angle formed by the extending direction of the inclined groove 12 and the extending and retracting direction of the telescopic rod 211 is an obtuse angle, and after the electromagnetic member is powered on by the inclined groove 12 in the inclined direction, the telescopic rod 211 moves outwards along with the buckling part 212, so that the telescopic rod 211 extends outwards.

In some embodiments of the present application, the sliding direction of the sliding bar 241 is perpendicular to the telescopic direction of the telescopic bar 211; the magnetic member 22 is installed at the bottom of the sliding rod 241, and an included angle formed between the extending direction of the inclined groove 12 and the extending and retracting direction of the telescopic rod 211 is an acute angle. At this time, after the electromagnetic element is powered on, the magnetic element 22 is attracted, and the sliding rod 241 is further driven to move downwards. The locking part 212 moves from a first position where the inclined groove 12 is close to the bottom end of the slide bar 241 to a second position where the inclined groove 12 is close to the top end of the slide bar 241. Since an included angle formed between the extending direction of the inclined groove 12 and the extending and retracting direction of the telescopic rod 211 is an acute angle, that is, the first position of the inclined groove 12 is farther away from the inner wall region of the earphone housing 10 where the through hole 11 is formed with respect to the second position of the inclined groove 12, the telescopic rod 211 is pushed to the outside of the earphone housing 10 during the movement of the buckling part 212. At this time, a stopper is disposed above the sliding bar 241 to limit the position of the top end of the sliding bar 241 after being reset. It will be appreciated that in this embodiment, when the catch portion 212 is in the first position of the chute 12, the slide bar 241 is not inserted to the bottom of the mounting post 14 to allow room for downward movement of the slide bar 241.
