Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

Referring to fig. 1, in an embodiment of the present application, a headset 10 is provided, where the headset 10 can be used to play sound. Further, in the embodiment of the present application, the wireless headset 10 is described as an example. Of course, the headset 10 provided herein may also be a wired headset 10.

The headset 10 includes a headset body 11 and an anti-loss assembly 12. Wherein the earphone body 11 can be used to be placed at a designated position of the user's ear, thereby playing sound to the user. The earphone body 11 may include a playing portion 01 for playing sound and an ear portion 02 connected to the playing portion 01. The loss prevention member 12 is mounted on the ear handle portion 02 to prevent the play portion 01 from being placed at a position designated by the user. Of course, in some embodiments of the present application, the earphone 10 may eliminate the ear portion 02 and the anti-lost assembly 12 may be mounted directly on the playing portion 01. It should be noted that, in the embodiment of the present application, the earphone body 11 represents a portion corresponding to one ear of the user, and in general, the earphone 10 may include two earphone bodies 11 and two loss prevention members 12, where the two earphone bodies 11 correspond to the two ears of the user, respectively. An anti-loss assembly 12 is mounted on the earphone body 11, optionally, the anti-loss assembly 12 is mounted on the ear portion 02 at an end away from the playing portion 01, and the anti-loss assembly 12 is used to prevent the earphone 10 from being lost.

Referring to fig. 2 and 3, the anti-lost device 12 includes a mounting body 100, a first magnet 210, a second magnet 220, and a pull rope 230. The mounting body 100 is mounted on the earphone body 11, and optionally, the mounting body 100 is mounted on an end of the ear handle portion 02 far from the playing portion 01. The first magnet 210 and the second magnet 220 are both detachably attached to the mounting body 100, and the first magnet 210 and/or the second magnet 220 are attached to the mounting body 100 by a pull string 230. Here, "and/or" indicates that only the first magnet 210 may be connected to the mounting body 100 through the pulling rope 230; alternatively, only the second magnet 220 may be connected to the mounting body 100 by the pulling rope 230; alternatively, the first magnet 210 is coupled to the mounting body 100 by a draw string 230, and the second magnet 220 is coupled to the mounting body 100 by the draw string 230. In the embodiment of the present application, only the first magnet 210 is connected to the mounting body 100 by the pulling string 230. Note that the first magnet 210 is connected to the mounting body 100 by a string 230, and one end of the string 230 is connected to the first magnet 210 and the other end is connected to the mounting body 100. Also, in the case where the first magnet 210 is detachably attached to the mounting body 100, the pulling rope 230 may be in a relaxed state at this time, in other words, the pulling rope 230 may not want the first magnet 210 to provide a force at this time; in the case that the first magnet 210 is detached from the mounting body 100, when the distance from the mounting body 100 to the first magnet 210 reaches a predetermined distance, the pull string 230 may provide a force to the first magnet 210 to prevent the first magnet 210 from continuously moving away from the mounting body 100.

As described above, in order to prevent the earphone body 11 from falling off when the earphone 10 is used, the first magnet 210 and the second magnet 220 may be detached from the mounting body 100, and then the first magnet 210 and the second magnet 220 may be held at a fixed position designated by the user, such as clothes, storage bags, or other articles that can be fixed on the body of the user, by the attractive interaction between the first magnet 210 and the second magnet 220. Because the first magnet 210 and/or the second magnet 220 are connected to the mounting body 100 through the pull rope 230, when the earphone body 11 falls off from the ear of the user, the earphone body 11 can be prevented from falling off through the actions of the first magnet 210, the second magnet 220 and the pull rope 230, and the technical problem of anti-lost of the earphone 10 is solved. Of course, when the earphone 10 needs to be retracted for placement, the first and second magnets 210 and 220 may be attached to the mounting body 100, thereby facilitating placement of the earphone 10. Further, the earphone 10 can prevent the earphone 10 from being lost without adding a connecting part for connecting the two earphone bodies 11, thereby achieving the purpose of not affecting the appearance of the earphone 10.

Of course, in the embodiment of the present application, the two earphone bodies 11 can be connected into a whole by the two first magnets 210 of the two earphone bodies 11 in the earphone 10 being magnetically connected to each other, and at this time, the two earphone bodies 11 can be hung on the user, for example, on the neck of the user, by the two pull cords 230, so as to facilitate the anti-lost of the earphone 10. It should be understood that in this case, the second magnet 220 may be kept mounted on the mounting body 100, or alternatively, two second magnets 220 may be magnetically connected to each other so that the earphone 10 is integrally formed in a ring shape, and thus, may be conveniently hung on the user as well for the purpose of anti-lost.

To facilitate the installation of the first magnet 210, optionally, in the embodiment of the present application, the installation main body 100 is provided with a first accommodating groove 111, and the first magnet 210 is detachably disposed in the first accommodating groove 111; wherein, the shape of the first receiving groove 111 is adapted to the shape of the first magnet 210, thereby facilitating the installation of the first magnet 210. In addition, in order to facilitate the installation of the second magnet 220, optionally, in the embodiment of the present application, a second accommodating groove 121 is further formed on the installation main body 100, and the second magnet 220 is detachably disposed in the second accommodating groove 121; wherein, the shape of the second receiving groove 121 is adapted to the shape of the second magnet 220, thereby facilitating the installation of the second magnet 220. It should be noted that in some embodiments of the present application, the provision of one or both of the first receiving groove 111 and the second receiving groove 121 may be eliminated. For example, a receiving groove may be provided in which both the first magnet 210 and the second magnet 220 are disposed. For another example, only one receiving groove may be provided, and the first magnet 210 or the second magnet 220 may be disposed in the receiving groove, and the other one may be detachably mounted on the mounting main body 100 by other methods, for example, a magnetic attraction method or an adhesion method may be adopted to realize the detachable connection with the mounting main body 100. For another example, the first receiving groove 111 and the second receiving groove 121 are both eliminated, and the first magnet 210 and the second magnet 220 are both magnetically attracted, adhered or clamped to be detachably connected to the mounting main body 100.

In addition, in the embodiment of the present application, the first receiving groove 111 and the second receiving groove 121 are respectively provided at both side surfaces of the mounting body 100 which are oppositely disposed, whereby the mounting of the first magnet 210 and the second magnet 220 can be facilitated.

The mounting body 100 is formed with a first outlet (not shown) disposed adjacent to the first receiving groove 111, and a pull rope 230 extends from the first outlet to facilitate connection with the first magnet 210. And/or, a second outlet (not shown) is formed on the mounting body 100, the second outlet is disposed near the second receiving groove 121, and the pulling rope 230 extends from the second outlet to facilitate connection with the second magnet 220. It should be noted that the first outlet and the second outlet may be arranged according to the arrangement of the pull rope 230; for example, in the case where only the first magnet 210 is coupled to the mounting body 100 by the pulling rope 230, a first outlet may be provided to facilitate the coupling of the first magnet 210 and the pulling rope 230; in the case where only the second magnet 220 is coupled to the mounting body 100 by the pulling rope 230, a second outlet may be provided to facilitate the coupling of the second magnet 220 and the pulling rope 230; in the case where the first and second magnets 210 and 220 are connected to the mounting body 100 by the pulling rope 230, respectively, a first outlet and a second outlet may be provided.

Alternatively, referring to fig. 3, fig. 4 and fig. 5 in combination, in an embodiment of the present application, the mounting body 100 may include a first shell 110 and a second shell 120, and the first shell 110 and the second shell 120 are detachably connected to facilitate mounting and assembling of the reset mechanism 300 and the pull rope 230. In this case, alternatively, the first magnet 210 may be detachably mounted on the first housing 110, and the second magnet 220 may be detachably mounted on the second housing 120. In the case where the first outlet and the second outlet are provided, the first outlet is provided on the first housing 110, and the second outlet is provided on the second housing 120.

In an embodiment of the present application, referring to fig. 2, 3 and 7 in combination, the anti-lost assembly 12 further includes a reset structure 300, the reset structure 300 is disposed inside the mounting body 100, and one end of the pull rope 230 is connected to the reset structure 300, and the other end is connected to the first magnet 210. In the case that the first magnet 210 is detached from the mounting body 100, a user may apply an external force to the first magnet 210 to pull the pulling rope 230, and under the external force, the pulling rope 230 is pulled out of the mounting body 100, and at the same time, the pulling rope 230 pulls the restoring structure 300 to be elastically deformed; under the action of the withdrawn external force, the reset structure 300 can drive the pulling rope 230 to retract into the installation main body 100 through the elastic reset action thereof, so as to provide a protection effect for the pulling rope 230 through the installation main body 100, and improve the condition that the pulling rope 230 is exposed to the outside and easily causes damage.

In the case of providing the reset mechanism 300, a portion of the pulling rope 230 may be disposed inside the installation body 100 when the pulling rope 230 is not used, so as to provide a protective effect to the pulling rope 230 through the installation body 100, thereby improving a situation that the pulling rope 230 is exposed to the outside and easily damaged. Of course, when the pulling rope 230 is required to be used, the pulling rope 230 can be led out from the installation body 100 by applying an external force to the first magnet 210, so that the first magnet 210 and the second magnet 220 can be conveniently clamped together at a position designated by a user. Moreover, when the first magnet 210 and the second magnet 220 need to be retracted, the pulling rope 230 can be retracted into the installation body 100 through the resetting function of the resetting structure 300, so that the pulling rope 230 can be conveniently stored, and a protective function is provided for the pulling rope 230.

The restoring structure 300 may include a rotation shaft 310 and a first elastic member 320. The rotating shaft 310 is rotatably coupled to the mounting body 100; one end of the first elastic member 320 is connected to the rotating shaft 310, and the other end is connected to the mounting body 100, so that the rotating shaft 310 can drive the first elastic member 320 to generate elastic deformation when rotating relative to the mounting body 100. One end of the pulling rope 230 is connected to the rotating shaft 310. It should be noted that, when the first elastic member 320 is not elastically deformed, at least a portion of the pulling rope 230 is wound around the rotating shaft 310. When a user applies an external force to the first magnet 210, the pulling rope 230 may be pulled by the first magnet 210, and the pulling rope 230 extends out of the installation body 100 under the external force and drives the rotation shaft 310 to rotate relative to the installation body 100, and at the same time, the rotation shaft 310 drives the first elastic member 320 to generate elastic deformation. In the case where the pulling string 230 is extended by a sufficient length from the mounting body 100, it is convenient that the first magnet 210 and the second magnet 220 are held at a user-designated position by magnetic coupling. When the earphone 10 needs to be stored, i.e. when the external force is removed, the rotation shaft 310 can rotate under the restoring action of the first elastic member 320, and the pulling rope 230 is wound around the rotation shaft 310 to retract the pulling rope 230 into the mounting body 100.

In the embodiment of the present application, the first elastic member 320 is provided as a torsion spring, and an end of the torsion spring located at the center is connected to the rotation shaft 310, and an end located at the outer side is connected to the mounting body 100. When the rotating shaft 310 rotates under the action of external force, the end part of the torsion spring can be driven to move, so that the torsion spring generates elastic deformation; in the case of canceling the external force, the torsion spring may rotate the rotation shaft 310 by the restoring action. Of course, in other embodiments of the present application, other elastic elements, such as an elastic connection string, may be used as the first elastic element 320.

In addition, in the embodiment of the present application, please refer to fig. 2, fig. 3 and fig. 6 in combination, the mounting body 100 may include a housing 101, a limiting post 140 and a supporting portion 130. The position-limiting column 140 is disposed inside the housing 101, and the abutting portion 130 is disposed inside the position-limiting column 140. The rotating shaft 310 is rotatably connected to the housing 101 and located inside the stopper column 140. The pulling rope 230 extends out of the casing 101 through the stopper post 140 and the casing 101, and the pulling rope 230 can increase the length of the extending outside of the casing 101 by the external force. The reset structure 300 may further include a stopper 330, the stopper 330 is disposed on the rotating shaft 310, and the stopper 330 may rotate along with the rotating shaft 310. The rotation shaft 310 is movably connected to the housing 101 while the rotation shaft 310 is rotatably connected to the housing 101, and the rotation shaft 310 can move in a first direction or a second direction opposite to the first direction with respect to the housing 101. The rotation shaft 310 can move along the first direction to enable the limiting block 330 to abut against the abutting portion 130, and at this time, the abutting portion 130 abuts against the limiting block 330 to stop the rotation of the limiting block 330, so that the rotation of the rotation shaft 310 is stopped, and the limitation of the rotation shaft 310 can be realized, so that the pull rope 230 can be in a stable state after extending out of the housing 101, and the magnetic connection between the first magnet 210 and the second magnet 220 is facilitated. In addition, the rotating shaft 310 can move along the second direction to separate the limiting block 330 from the abutting portion 130, and at this time, the mutual abutting between the limiting block 330 and the abutting portion 130 can be released, so that the limiting block 330 and the rotating shaft 310 can rotate freely, thereby facilitating the rotating shaft 310 to drive the pulling rope 230 to retract into the housing 101.

It should be noted that, in some embodiments of the present application, the first direction and the second direction both coincide with a central axis of the rotating shaft 310, that is, the rotating shaft 310 can reciprocate linearly along the central axis thereof to drive the limiting block 330 to selectively abut against the abutting portion 130 or separate from the abutting portion 130. Of course, in other embodiments, the first direction and the second direction may also be directions perpendicular to the rotating shaft 310, and in this case, only the sliding groove for sliding the rotating shaft 310 needs to be disposed on the casing 101.

In order to facilitate the installation of the rotating shaft 310, in the embodiment of the present application, the housing 101 is provided with a first installation hole 102 adapted to the rotating shaft 310, and the rotating shaft 310 is movably matched with the first installation hole 102; in other words, the rotation shaft 310 may rotate in the first mounting hole 102 while the rotation shaft 310 may linearly reciprocate in the first mounting hole 102 in the first and second directions. In addition, in order to facilitate the user to operate the rotating shaft 310, the rotating shaft 310 extends out of the casing 101 through the casing 101, and the user can press the rotating shaft 310 to move the rotating shaft 310 in the second direction or the first direction. That is, the rotation shaft 310 protrudes from the housing 101 from the first mounting hole 102.

As described above, the manner in which the user uses the headset 10 to prevent loss may be as follows: the first magnet 210 and the second magnet 220 may be detached from the mounting body 100 when the user places the earphone body 11 at a designated position for sound playing. The user can first move the rotation shaft 310 in the second direction to disengage the limiting block 330 from the holding portion 130, and then apply an external force to the first magnet 210 to extend the pull rope 230 out of the casing 101; when the pulling rope 230 extends out of the casing 101 and moves, the pulling rope 230 drives the rotating shaft 310 to rotate, and the rotating shaft 310 drives the first elastic member 320 to generate elastic deformation. When the pulling rope 230 extends for a sufficient length, the user can move the rotating shaft 310 along the first direction to make the limiting block 330 and the abutting portion 130 abut against each other, and at this time, the abutting portion 130 and the limiting block 330 abut against each other to provide an external force to the rotating shaft 310 to counteract the elastic restoring force of the first elastic member 320, thereby ensuring that the extended pulling rope 230 has a stable state. The user can be commonly held at a user-designated position by the mutual magnetic coupling of the first magnet 210 and the second magnet 220, thereby enabling the anti-loss purpose of the earphone body 11. Of course, when the user needs to store the earphone 10, the user may move the rotation shaft 310 in the second direction to disengage the limiting block 330 from the abutting portion 130, and under the elastic restoring force of the first elastic member 320, the rotation shaft 310 rotates and winds the pulling rope 230 on the rotation shaft 310, and at the same time, retracts the pulling rope 230 into the housing 101, thereby storing the pulling rope 230. The user can also load the first magnet 210 and the second magnet 220 into corresponding positions on the mounting body 100, so that the accommodation of the earphone 10 can be completed.

Optionally, in the embodiment of the present application, in order to facilitate the arrangement of the abutting portion 130, and to facilitate the abutting portion 130 and the limiting block 330 to be matched with each other, the mounting main body 100 may further include a rotation matching portion 150. The rotation matching part 150 is disposed inside the position-limiting column 140, and the rotation matching part 150 and the position-limiting column 140 together form a first cavity 151. The rotation shaft 310 is movably engaged with the rotation engaging portion 150, so that the rotation shaft 310 can move along the first direction or the second direction relative to the rotation engaging portion 150, and the rotation shaft 310 can also rotate relative to the rotation engaging portion 150, and the rotation center of the rotation shaft 310 is the central axis of the rotation shaft 310. And one end of the rotation shaft 310 extends into the first cavity 151, the limiting block 330 is disposed inside the first cavity 151, and the abutting portion 130 is disposed on the rotation matching portion 150 and located inside the first cavity 151, so that the abutting portion 130 and the limiting block 330 can be matched with each other conveniently.

It should be noted that, in order to facilitate the mutual matching between the rotating matching portion 150 and the rotating shaft 310, a second mounting hole 153 is formed in the rotating matching portion 150, the second mounting hole 153 is communicated with the first cavity 151, and the rotating shaft 310 passes through the second mounting hole 153 and extends into the first cavity 151. By the arrangement of the first mounting hole 102 and the second mounting hole 153, the rotation shaft 310 can be ensured to be capable of moving in the first direction and the second direction, and the rotation shaft 310 can be ensured to be capable of rotating relative to the housing 101 and the rotation matching part 150. In addition, the limiting block 330 is substantially in a long strip shape, and the length of the limiting block 330 is greater than the diameter of the second mounting hole 153, in other words, the limiting block 330 can prevent the rotating shaft 310 from coming out of the second mounting hole 153, so that the rotating shaft 310 and the rotating matching part 150 can be stably matched.

In addition, optionally, in the embodiment of the present application, the supporting portion 130 is convexly disposed on the rotation matching portion 150, the supporting portion 130 is multiple, the multiple supporting portions 130 are disposed at intervals and surround the second mounting hole 153, optionally, in the embodiment of the present application, the supporting portion 130 is four, and it should be understood that, in other embodiments, the supporting portion 130 may also be two, three, five, or six, and the like. When the limiting block 330 and the abutting portions 130 are engaged with each other, the end of the limiting block 330 is located between two adjacent abutting portions 130, and the limiting block 330 abuts against at least one of the abutting portions 130. In order to facilitate the mutual matching between the limiting block 330 and the abutting portions 130, the distance between two adjacent abutting portions 130 is greater than the width of the limiting block 330, so that the limiting block 330 can fall between two adjacent abutting portions 130, and the limiting block and the abutting portions 130 can be matched with each other conveniently. In addition, in order to facilitate the separation of the abutting portion 130 and the limiting block 330, a gap is formed between the abutting portion 130 and the housing 101, so that when the limiting block 330 moves along the second direction along with the rotating shaft 310, the limiting block 330 can be made to correspond to the gap, thereby separating the limiting block 330 and the abutting portion 130 from each other.

Optionally, in the embodiment of the present application, one side of the abutting portion 130 is provided with the guiding inclined surface 131, so that the abutting portion 130 forms a wedge shape, and when the limiting block 330 abuts on the guiding inclined surface 131, the guiding inclined surface 131 is used to guide the limiting block 330 to bypass the abutting portion 130, in other words, even if the end of the limiting block 330 is located between two adjacent abutting portions 130, the limiting block 330 can bypass the abutting portion 130 by the guiding action of the guiding inclined surface 131, so that the limiting block 330 and the rotating shaft 310 can rotate freely.

For example, when the angle of view in fig. 9 is taken, the limiting block 330 can abut against the guiding inclined plane 131 when rotating clockwise, and at this time, the limiting block 330 can bypass the abutting portion 130 by the guiding action of the guiding inclined plane 131; the limiting block 330 can abut against the other side surface of the abutting portion 130 when rotating counterclockwise, so that the abutting portion 130 and the limiting block 330 can abut against each other. When the pulling rope 230 extends out of the casing 101 and drives the rotating shaft 310 to rotate, the rotating shaft 310 rotates clockwise, and at this time, even if the user does not move the rotating shaft 310 in the second direction to separate the limiting block 330 from the abutting portion 130, the rotating shaft 310 and the limiting block 330 can freely rotate by the arrangement of the guiding inclined plane 131, so that the pulling rope 230 is pulled out of the casing 101 by the user. When the user pulls the pulling rope 230 to a proper length, the user cancels the external force, and the rotating shaft 310 rotates counterclockwise under the action of the first elastic member 320, so as to drive the limiting block 330 to abut against the abutting portion 130, thereby achieving the mutual abutting of the limiting block 330 and the abutting portion 130. In other words, when the user needs to pull the pulling rope 230 out of the casing 101, the pulling rope 230 can be directly pulled out of the casing 101 by applying an external force to the pulling rope 230 without having to disengage the stopper 330 and the abutting portion 130 from each other by moving the rotating shaft 310 in the second direction. Of course, when the user needs to store the pulling rope 230 into the installation body 100, the limiting block 330 and the abutting portion 130 need to be separated from each other by moving the rotating shaft 310 along the second direction, so that the rotating shaft 310 rotates counterclockwise under the elastic restoring force of the first elastic member 320, and the pulling rope 230 is wound on the rotating shaft 310, thereby achieving the purpose of storing the pulling rope 230 in the housing 101.

Referring to fig. 2 and 8, the rotation matching portion 150 and the position-limiting column 140 further form a second cavity 152, and the second cavity 152 and the first cavity 151 are located at two opposite sides of the rotation matching portion 150. Wherein the rotating shaft 310 is partially located in the second cavity 152, and the pulling rope 230 is received in the second cavity 152; and, the first elastic member 320 is disposed in the second cavity 152. Therefore, the pull rope 230 can be conveniently stored, a limiting effect can be provided for the first elastic piece 320 through the second cavity 152, and the installation stability of the first elastic piece 320 is improved. In addition, the position-limiting column 140 is provided with a notch 141, the notch 141 penetrates through the peripheral wall of the position-limiting column 140 and is communicated with the second cavity 152, and the pull rope 230 penetrates through the notch 141 and extends into the second cavity 152 to be connected with the rotating shaft 310. By providing the notch 141, a guiding function can be provided to the pulling rope 230, and the pulling rope 230 is prevented from being wound and knotted in a loose state, thereby ensuring the overall stability of the reduction structure 300.

In the embodiment of the present application, the restoring structure 300 may further include a second elastic member 340, and one end of the second elastic member 340 is connected to the rotating shaft 310 and the other end is connected to the housing 101. The rotating shaft 310 drives the second elastic member 340 to generate elastic deformation under the condition of moving along the second direction; the second elastic member 340 serves to drive the rotation shaft 310 to move in the first direction upon elastic restoration. In other words, by the arrangement of the second elastic member 340, before the external force moving toward the second direction is applied to the rotating shaft 310, the position of the rotating shaft 310 can be maintained at the purpose that the limiting block 330 is located between the two adjacent abutting portions 130.

When the rotating shaft 310 rotates clockwise as viewed in fig. 9, the stopper 330 can bypass the abutting portion 130 by the guiding action of the guiding inclined surface 131. Under the condition that the limiting block 330 slides on the guiding inclined plane 131, the limiting block 330 simultaneously moves along the second direction and drives the rotating shaft 310 to move along the second direction, so that the second elastic member 340 generates elastic deformation. After the limiting block 330 bypasses the abutting portions 130, the limiting block 330 returns to between two adjacent abutting portions 130 through the restoring action of the second elastic member 340, so that under the condition that the external force of the pulling rope 230 is cancelled, the limiting block 330 and the abutting portions 130 abut against each other through the restoring action of the first elastic member 320, the pulling rope 230 is prevented from being completely withdrawn into the housing 101, and the operation is convenient for a user.

At this time, in a case where the user applies an external force to the rotation shaft 310 to move toward the second direction, that is, in a case where the user presses the rotation shaft 310 extending out of the housing 101, the rotation shaft 310 moves in the second direction while bringing the second elastic member 340 into elastic deformation. The limit block 330 and the abutting portion 130 can be separated from each other, so that the rotation shaft 310 and the limit block 330 can be freely rotated relative to the housing 101. In this case, a user can apply an external force to the pulling rope 230 to pull the pulling rope 230 out of the casing 101, and at the same time, the rotating shaft 310 is driven to rotate, and since the limiting block 330 and the abutting portion 130 are separated from each other, the user can easily pull the pulling rope 230 out; of course, the rotation shaft 310 may be rotated by the elastic restoring action of the first elastic member 320, so that the pulling rope 230 is wound around the rotation shaft 310, thereby achieving the purpose that the pulling rope 230 is received in the casing 101.

It should be understood that in some embodiments of the present application, the second elastic member 340 may be eliminated, and a third mounting hole (not shown) may be formed in the housing 101, and the third mounting hole is formed on the other side of the housing 101, so that the end of the rotating shaft 310 far from the first mounting hole 102 may protrude from the third mounting hole, and at this time, the user may press the rotating shaft 310 protruding from the third mounting hole to achieve the purpose of moving the rotating shaft 310 in the first direction.

To facilitate the installation of the second elastic element 340, optionally, in the embodiment of the present application, the housing 101 is provided with a first accommodating hole 103 for accommodating the second elastic element 340, and one end of the second elastic element 340 is accommodated in the first accommodating hole 103. In addition, a second accommodating hole 311 extending along the axis is formed at an end of the rotating shaft 310 close to the second elastic member 340, and the other end of the second elastic member 340 extends into the second accommodating hole 311. By the arrangement of the first receiving hole 103 and the second receiving hole 311, the mounting stability of the second elastic member 340 can be ensured.

In summary, in the earphone 10 provided in the embodiment of the present application, in order to prevent the earphone body 11 from falling off when in use, the first magnet 210 and the second magnet 220 may be detached from the mounting body 100, and then the first magnet 210 and the second magnet 220 may be held at a fixed position designated by a user by an attractive interaction between the first magnet 210 and the second magnet 220. Because the first magnet 210 and/or the second magnet 220 are connected to the mounting body 100 through the pull rope 230, when the earphone body 11 falls off from the ear of the user, the earphone body 11 can be prevented from falling off through the actions of the first magnet 210, the second magnet 220 and the pull rope 230, and the technical problem of anti-lost of the earphone 10 is solved. Of course, when the earphone 10 needs to be retracted for placement, the first and second magnets 210 and 220 may be attached to the mounting body 100, thereby facilitating placement of the earphone 10. Further, the earphone 10 can prevent the earphone 10 from being lost without adding a connecting part for connecting the two earphone bodies 11, thereby achieving the purpose of not affecting the appearance of the earphone 10. And under the condition that the reset structure 300 is arranged, the use difficulty of the earphone 10 can be reduced, and the use experience of a user can be improved.
