The connecting member includes a first rotating shaft 23 and a second rotating shaft 24 which are perpendicular to each other, and the inner housing 21 is connected to the first rotating shaft 23 and can rotate around the first rotating shaft 23. The first rotating shaft 23 and the second rotating shaft 24 are perpendicular to each other, and the direction of the second rotating shaft 24 is the Y direction with the direction of the first rotating shaft 23 as the X direction. The first rotating shaft 23 and the second rotating shaft 24 may be directly connected to each other or may be connected to each other by a connecting portion such as a connecting shaft 25 to form an integral connecting structure. The inner shell 21 and the outer shell 22 are connected in a rotating manner through a connecting piece. Wherein, first pivot 23 is connected with inner shell 21 is rotated, then inner shell 21 can rotate around first pivot 23, specifically can be connected first pivot 23 with inner shell 21 through clamp etc. on the one hand can realize inner shell 21 around the rotation of first pivot 23, with first pivot 23 spacing installation on inner shell 21 simultaneously. When the user adjusts the ear shell 2 in the X direction, the inner shell 21 rotates around the first rotation axis 23 by rotating the inner shell 21 around the X direction.

That is to say that inner shell 21 rotates around first pivot 23, because third spacing hoop 32 and inner shell 21 fixed connection, then along with inner shell 21 synchronous rotation, first location axle 29 on the first pivot 23 inserts in the first bar hole 28 of third spacing hoop 32, then along with the rotation of third spacing hoop 32, first bar hole 28 rotates first location axle 29 relatively, the spacing effect of direction of rotation has further been played, and when first bar hole 28 rotated first location axle 29 and the tip of first bar hole 28 offseted, then third spacing hoop 32 can not continue to rotate, that is to say inner shell 21 is restricted towards the rotation of corresponding direction. Similarly, when the first positioning shaft 29 abuts against the other end of the first elongated hole 28 when the first elongated hole 28 rotates, the rotation of the inner shell 21 in that direction is also limited. Therefore, the first strip-shaped hole 28 is matched with the first positioning shaft 29 to play a role in positioning and limiting, and the position and the rotation angle are limited.

Further, an inner shell mounting groove is formed in the inner shell 21, the first limiting hoop 26 and the inner shell mounting groove are matched to form a first limiting groove with a circular cross section, and the third limiting hoop 32 and the inner shell mounting groove are matched to form a third limiting groove with a circular cross section.
