The connection member 220 is movably connected to the sound guide tube 110 to drive the ear-inserting portion 210 to move close to or away from the casing 100, so as to adjust the distance between the ear-inserting portion 210 and the casing 100, thereby realizing the function of switching the earphone between the semi-in-ear type and the in-ear type. Meanwhile, by arranging the anti-disengaging structure between the connecting piece 220 and the sound guide tube 110, the anti-disengaging structure can limit the moving position of the connecting piece 220 in the direction away from the shell 100, so that the connecting piece 220 is prevented from being disengaged from the sound guide tube 110, and the effect of improving the reliability of the earphone structure is achieved.

In order to prevent the connection element 220 from falling off the sound tube 110 during the switching process of the earphone to the in-ear state, referring to fig. 8 to 9, in an embodiment of the present invention, the anti-falling structure includes a position-limiting buckle 410 and a position-limiting groove 420, the position-limiting buckle 410 is disposed on one of the connection element 220 and the sound tube 110, and the position-limiting groove 420 is disposed on the other of the connection element 220 and the sound tube 110; the limit buckle 410 is slidably inserted into the limit groove 420.

In this embodiment, one of the connecting element 220 and the sound guiding tube 110 is provided with a limiting buckle 410, the other one of the connecting element 220 and the sound guiding tube 110 is provided with a limiting groove 420, and the limiting buckle 410 is embedded in the limiting groove 420 in a sliding manner, so that when the connecting element 220 moves outwards relative to the sound guiding tube 110, the groove wall of the limiting groove 420 can stop the limiting buckle 410, thereby preventing the connecting element 220 from falling off from the sound guiding tube 110, further preventing the ear cap 200 from falling off from the casing 100, and ensuring the reliability of the whole structure of the earphone.

Optionally, the position-limiting buckle 410 is located on the connecting member 220, the position-limiting groove 420 is located on the sound guide tube 110, at this time, the position-limiting groove 420 is a sunken groove structure formed by the inner concave of the wall surface of the sound guide tube 110, and has a groove bottom wall and a groove side wall surrounding the periphery of the groove bottom wall, the groove opening is opposite to the groove bottom wall, the position-limiting buckle 410 passes through the groove opening to be embedded in the sunken groove structure, and the groove side wall of the position-limiting groove plays a role in limiting the position-limiting buckle 410. In order not to affect the movement of the connection member 220, the extending direction of the limiting groove 420 is the same as the moving direction of the connection member 220, so that the groove sidewalls of the limiting groove 420 located at the opposite sides of the limit buckle 410 and the same as the moving direction of the connection member 220 guide the limit buckle 410, and the movement of the connection member 220 relative to the sound guide tube 110 is more stable. Meanwhile, the groove sidewall of the limiting groove 420 perpendicular to the moving direction of the connecting element 220 acts as a stop for the limiting buckle 410 to limit the continuous movement of the connecting element 220.

In an embodiment, the stop buckle 410 may be disposed at an end of the connection element 220, so that the connection element 220 and the sound guide tube 110 have a sufficiently long movement path, and at the same time, compactness of the internal structure layout of the earphone is ensured, and the product volume is reduced.

In practical applications, the shape and structure of the position-limiting buckle 410 may not be limited, and may be a square structure, a triangular structure, a circular structure, or other special-shaped structures. In this embodiment, considering that the position-limiting buckle 410 needs to slide inside the position-limiting groove 420, the outer surface of the position-limiting buckle 410 may be designed to have an arc shape without corners, so as to reduce the friction between the position-limiting buckle 410 and the position-limiting groove 420.

In an embodiment of the present invention, referring to fig. 3 to 9, the earphone further includes a limiting structure 300, and the limiting structure 300 is disposed between the connecting element 220 and the sound guiding tube 110, so that at least two relatively fixed connecting positions are disposed between the connecting element 220 and the sound guiding tube 110, and the two connecting positions are spaced in the moving direction.

It can be understood that the connection element 220 and the sound guide tube 110 are relatively moved, and the limiting structure 300 is used for limiting the relative position between the connection element 220 and the sound guide tube 110, and thus between the ear cap 200 and the casing 100. When the user wants to insert the earphone into the ear in half, the connecting element 220 can be moved to the connecting position near one side of the casing 100 to be fixed relative to the sound guide tube 110, and at this time, the connecting element 220 can drive the ear-inserting part 210 to move to the position near the casing 100, that is, the distance between the ear-inserting part 210 and the casing 100 is shortened, so as to form the half-in-ear earphone. When the user wants to insert the earphone into the ear, the connecting element 220 can be moved to the connecting position on the side far from the casing 100 to be relatively fixed with the sound guiding tube 110, and at this time, the connecting element 220 can drive the ear-inserting part 210 to move to the position far from the position close to the casing 100, that is, the distance between the ear-inserting part 210 and the casing 100 is increased, so as to form the in-ear earphone.

In practical applications, the specific structural form of the position-limiting structure 300 may be determined according to practical situations, such as a snap structure, a threaded structure, or a magnetic structure.
