The earphone connection structure 1 provided by the embodiment of the invention has the following characteristics:

above-mentioned earphone connection structure 1, through set up iron-based subassembly 14 in its slip track 12, make the activity stretch into this slip track 12 in magnetic sliding arm 11 lean on the contact mutually with this iron-based subassembly 14 and adsorb mutually, like this, under the effect of magnetic force, make in the slip magnetic sliding arm 11 can and iron-based subassembly 14 between produce even frictional force, this even frictional force can make the dynamics that user pulling magnetic sliding arm 11 suitable and feel comfortable, so, under the dual function of magnetic force and frictional force, make the slip of magnetic sliding arm 11 stable and smooth and easy, thereby user's experience has been promoted, earphone quality has been improved.

Further, in the embodiment of the present invention, a containing groove 120 is formed on both the front side and the back side of the head end of the sliding rail 12, the containing groove 120 is adapted to the shape and the size of the iron-based component 14, and the iron-based component 14 is contained in the containing groove 120 and is in contact with both the front side and the back side of the magnetic sliding arm 11. Of course, in other embodiments of the present invention, the ferrous assembly 14 may be installed in the sliding track 12 by other methods, which are not limited herein.

Further, in the embodiment of the present invention, the front side and the back side of the head end of the sliding rail 12 are respectively provided with a receiving groove 120, and two iron-based components 14 are respectively received in the two receiving grooves 120, that is, the front side and the back side of the head end of the sliding rail 12 are respectively provided with one iron-based component 14, where the two iron-based components 14 respectively abut against the front side and the back side of the magnetic sliding arm 11 extending into the sliding rail 12. Of course, in other embodiments of the present invention, other numbers of iron-based components 14 may be disposed in the sliding rail 12 according to practical situations and requirements, and are not limited herein.

Further, in the embodiment of the present invention, the iron assembly 14 may include a seamless sleeve 141 and an iron member 142, and the iron member 142 has a plate-like structure, and is wrapped in the seamless sleeve 141. During assembly, after the iron-based components 14 are accommodated in the accommodating groove 120, the seamless sleeves 141 on the surface layers of the two sets of iron-based components 14 are respectively in contact with the front side and the reverse side of the magnetic sliding arm 11, so that when the magnetic sliding arm 11 slides, the iron base members 142 in the seamless sleeves 141 are adsorbed to the magnetic sliding arm 11, and the seamless sleeves 141 are in contact with the magnetic sliding arm 11 and generate friction; of course, when the magnetic slider 11 is at rest, the iron member 142 and the magnetic slider 11 are also attracted to each other. Here, by providing the seamless sleeve 141 and enclosing the iron base 142 therein, the iron base 142 is easily assembled, and also by causing friction between the seamless sleeve 141 and the magnetic slider arm 11, the magnetic slider arm 11 is easily slid smoothly.

When the magnetic sliding arm 11 slides telescopically, the limit buckle 111 slides synchronously along with the sliding of the magnetic sliding arm 11, and the sliding range of the limit buckle 111 is about the length of the open slot 1200. Correspondingly, a blocking piece 131 is convexly arranged on the inner wall of the housing 13, which is sleeved on the periphery of the sliding rail 12, the blocking piece 131 protrudes from the inner wall of the housing 13 and extends into the open slot 1200, and the blocking piece 131 is located on the inner wall of the housing 13 near the head end thereof. Here, the blocking piece 131 is used to block the limiting buckle 111 on the magnetic sliding arm 11 to limit the magnetic sliding arm 11 from being separated from the sliding track 12, that is, in the process of sliding the magnetic sliding arm 11 out of the sliding track 12, a blocking limit is formed after the limiting buckle 111 contacts with the blocking piece 131, so that the magnetic sliding arm 11 is limited to continuously slide out of the sliding track 12, and thus, the sliding limit is realized, and the limiting is reliable. Of course, according to practical situations and requirements, in other embodiments of the present invention, the magnetic sliding arm 11 and the sliding rail 12 may be limited in sliding by other means, which is not limited herein.

Further, in the embodiment of the present invention, the head end of the sliding rail 12 is sleeved with a sleeve 15, one end of the sleeve 15 is open, and the other end of the sleeve 15 is open, specifically, the sleeve 15 is sleeved on the head end of the sliding rail 12 through the open end thereof and is abutted with the end surface of the head end of the housing 13 sleeved on the periphery of the sliding rail 12, and meanwhile, the head end of the magnetic sliding arm 11 movably inserted in the sliding rail 12 movably penetrates through the open end of the sleeve 15, where the open end is the head end of the sleeve 15. Here, since the iron-based component 14 is accommodated in the accommodating groove 120 at the head end of the sliding rail 12, the iron-based component 14 is effectively prevented from falling out of the sliding rail 12 by the sleeve 15 covering the head end of the sliding rail 12. Of course, according to practical and specific requirements, in other embodiments of the present invention, the iron-based component 14 may be limited from falling out of the receiving groove 120 of the sliding rail 12 by other means, which is not limited herein.
