[0023] The specific arrangement and function of the adjusting device 6 and the limiting device 7 will be described in detail below.

[0024] In this embodiment: an adjusting device 6 is provided on the side of the U-shaped frame 1, and the adjusting device 6 includes a supporting plate 61, and the supporting plate 61 is fixedly installed on the side of the U-shaped frame 1. A sleeve 62 is fixedly installed on the surface of the supporting plate 61, and a sliding rod 63 is slidably connected inside the sleeve 62. An operating plate 64 is fixedly installed on the surface of one end of the sliding rod 63 away from the sleeve 62.

[0025] In this embodiment, the arrangement of the sleeve 62 and the sliding rod 63 enables the operating plate 64 to move stably.

[0026] Specifically, a spring 65 is fixedly mounted on the surface of the operating plate 64 , and one end of the spring 65 away from the operating plate 64 is fixedly connected to the sleeve 62 .

[0027] In this embodiment, the setting of the spring 65 has the effect of limiting the position of the operating plate 64 .

[0028] Specifically, a limiting rod 66 is fixedly mounted on the surface of the operating plate 64, and a plurality of limiting holes 67 are formed in an annular shape on the outer wall surface of the rotating rod 2. The setting of the limiting rod 66 and the limiting holes 67 has the effect of limiting the rotation of the rotating rod 2.

[0029] In this embodiment: a limiting device 7 is provided on one side surface of the U-shaped frame 1 away from the support plate 61, and the limiting device 7 includes a U-shaped plate 71, and the U-shaped plate 71 is fixedly installed on the one side surface of the U-shaped frame 1 away from the support plate 61, and a threaded rod 72 is rotatably connected between the inner walls at both ends of the U-shaped plate 71, and a hand wheel 73 is fixedly installed on one end of the threaded rod 72. When the ear hook rod 9 is damaged and needs to be replaced, the hand wheel 73 is first turned. The rotation of the hand wheel 73 drives the threaded rod 72 to rotate. The rotation of the threaded rod 72 drives the movable plate 75 to move inside the groove 74. The movable plate 75 moves inside the groove 74 and drives the positioning rod 76 to move. The positioning rod 76 moves to move itself out from the inside of the positioning hole 77. The positioning rod 76 and the positioning hole 77 are separated so that the ear hook rod 9 loses its limit inside the mounting seat 8. At this time, the ear hook rod 9 can be moved out from the inside of the mounting seat 8, completing the disassembly operation of the ear hook rod 9. Through the cooperation of the above structure, the ear hook rod 9 can be disassembled, so that it is convenient to replace the ear hook rod 9 when it is damaged, avoiding the discarding of the entire device, and further reducing the user's usage cost.

[0030] Specifically, a groove 74 is formed on the inner wall surface of the U-shaped plate 71 , and a movable plate 75 is threadedly connected to the surface of the threaded rod 72 .

[0031] In this embodiment, the threaded rod 72 is provided to drive the moving plate 75 to move inside the groove 74 .

[0032] Specifically, a positioning rod 76 is fixedly installed on the surface of the movable plate 75 , and a positioning hole 77 is opened on the outer wall surface of the ear-hanging rod 9 .

[0033] In this embodiment, the arrangement of the positioning rod 76 and the positioning hole 77 has the effect of limiting the ear-hanging rod 9 inside the mounting seat 8 .

[0034] Working principle: by setting the adjustment device 6, when it is needed to use it again, when adjusting the angle of the casing 4, first move the operating plate 64, and the movement of the operating plate 64 drives the sliding rod 63 to move into the inside of the sleeve 62. At the same time, the movement of the operating plate 64 also squeezes the spring 65, so that the spring 65 is compressed and drives the limit rod 66 to move. The limit rod 66 moves to move itself out from the inside of the limit hole 67, and the limit rod 66 and the limit hole 67 are separated to make the rotating rod 2 lose the limit. At this time, the casing 4 can be rotated. When the casing 4 is rotated to a suitable angle, release the operating plate 64, and use the rebound force of the spring 65 to make the limit rod 66 reinsert into the corresponding limit hole 67 to re-limit the rotation of the rotating rod 2. Through the cooperation of the above structure, the angle of the casing 4 can be adjusted, so that the deflection angle of the sound outlet 5 relative to the ear canal can be changed, and then the sound outlet 5 can present different listening effects to match the needs of users. When the ear hook rod 9 is damaged and needs to be replaced, the hand wheel 73 is first turned. The rotation of the hand wheel 73 drives the threaded rod 72 to rotate. The rotation of the threaded rod 72 drives the movable plate 75 to move inside the groove 74. The movable plate 75 moves inside the groove 74 and drives the positioning rod 76 to move. The positioning rod 76 moves to move itself out from the inside of the positioning hole 77. The positioning rod 76 and the positioning hole 77 are separated so that the ear hook rod 9 loses its limit inside the mounting seat 8. At this time, the ear hook rod 9 can be moved out from the inside of the mounting seat 8, completing the disassembly operation of the ear hook rod 9. Through the cooperation of the above structure, the ear hook rod 9 can be disassembled, so that it is convenient to replace the ear hook rod 9 when it is damaged, avoiding the discarding of the entire device, and further reducing the user's usage cost.
