The inner part of the sleeve 32 A fixing spring 33 is fixedly connected to the connecting plate 31. The fixing spring 33, the sleeve 32 and one side of the connecting plate 31 are located on the same center line. One end of the back side of the fixing spring 33 is fixedly connected to the inner wall of the back side of the rotating drum 23 of the mounting mechanism 2. The diameter of the fixing spring 33 is smaller than the inner diameter of the sleeve 32. Two positioning grooves 34 are symmetrically provided on the other side of the back side of the connecting plate 31. Both of the two positioning grooves 34 are arc-shaped and are located on the same center line as the other side of the connecting plate 31. The connecting plate 31 at the center of the two positioning grooves 34 is threaded with a mounting screw. The bolt 35 is provided with a mounting slot 36 at the upper front end of the connecting plate 31. A rotating plate 38 is clamped inside the mounting slot 36. The lower ends of both sides of the rotating plate 38 are rotatably connected to the inner wall of the mounting slot 36 via second rotating shafts 37. The thickness of the rotating plate 38 matches the depth of the mounting slot 36. A through slot 39 is longitudinally provided in the middle of the rotating plate 38. A pull slot 310 is provided at the upper back end of the rotating plate 38. The lower end of the rotating plate 38 is in an arc-shaped structure and abuts against the lower inner wall of the mounting slot 36.

During operation, the hearing aid body 1 receives external sounds, processes the sounds, and transmits them to the user, allowing the user to hear the surrounding sounds. During this process, if the processed sounds are too loud, the sound-absorbing cover 41 and the several sound-absorbing holes 43 provided will eliminate the recovered external sounds, making it difficult for the hearing aid body 1 to receive the external sounds.
