Abstract: A structure capable of adjusting the position and angle of an ear housing, comprising an ear housing (7), a rotating shaft (8), an ear sleeve assembly (9), a gland (10), an ear housing assembly (12), a rotating shaft mounting groove position (13), and second screws (11). The ear housing is fixed on the rotating shaft; the rotating shaft is fixed on a sliding sleeve (2); the sliding sleeve is sleeved at the tail end of a steel headband (1); the ear housing assembly is capable of rotating about the rotating shaft so as to adjust the ear sleeve assembly in the ear housing assembly. When a headphone is worn, the ear sleeve assembly in the ear housing assembly can align with the ears of users in different head shapes in a vertical direction, so as to reduce audio leakage, the angle of the ear sleeve assembly in the ear housing assembly is adjustable, so as to fit the facial areas in front of, behind, above, and below the ears, thereby reducing audio leakage, and when the position of the ear housing part of the headphone is adjusted, the impact on the headband structure can be reduced, so as to avoid the problem of reduction in wearing comfort due to a large change in the clamping force of the headband.
