[0031] A protective sleeve 6 is provided on the outside of the knob 13, rotating grooves 15 are provided on the upper and lower sides of the knob 13, a bolt 14 is provided on the knob 13, a rotating shaft 62 is provided on the outside of the protective sleeve 6, a bayonet 61 is provided on the protective sleeve 6, and the bayonet 61 is connected to the bolt 14. Since the knob 13 protrudes relatively, it is easy to be damaged when it is bumped or dropped, that is, the knob 13 is protected by the protective sleeve 6, and the rotating shaft 62 is stuck in the rotating groove 15 and rotated, so that the protective sleeve 6 is fixed on the outside of the knob 13, and is connected to the bolt 14 through the bayonet 61, so that the protective sleeve 6 drives the knob 13 to rotate.

[0032] A protective mechanism is arranged inside the housing 1 of the speaker, and the protective mechanism is used to protect the inside of the speaker. The protective mechanism includes an insulating pad 4 and a protective member 43. The insulating pad 4 is arranged at the bottom of the inner side of the speaker housing 1, and the protective member 43 is arranged above the insulating pad 4. The insulating pad 4 is provided with a mounting groove 41. The internal structure of the speaker is arranged on the mounting groove 41. The bottom insulating pad 4 insulates it. A second shock absorbing spring 42 is arranged on the protective member 43. The second shock absorbing spring 42 is connected to the top of the inner side of the speaker housing 1. A damper 44 is arranged inside the second shock absorbing spring 42. When vibration occurs, the internal structure is protected by the upper protective part 43, and the second shock-absorbing spring 42 cooperates with the internal damper 44 to achieve a shock-absorbing effect. Mounting plates 5 are provided on both sides of the interior of the speaker housing 1, and springs 51 are provided on the outside of the mounting plates 5. The springs 51 are connected to the inner wall of the speaker housing 1, and the mounting plates 5 are installed on the internal structure of the speaker through the springs 51. A sliding tube 52 is provided on the inside of the speaker housing 1, and sliders 53 are provided on the upper and lower sides of the mounting plate 5.

That is, when the device falls and one side of the support block 55 falls to the ground, the first shock-absorbing spring 54 cooperates with the damper 44 to achieve a shock-absorbing effect.

[0034] Working principle: The speaker protects the knob 13 through the protective cover 6, and is stuck on the rotating groove 15 through the rotating shaft 62 and rotated, so that the protective cover 6 is fixed on the outside of the knob 13, and the latch 14 is connected through the bayonet 61, so that the protective cover 6 drives the knob 13 to rotate. When the speaker is bumped, the mounting head 31 is connected to the mounting port 32, so that the protective pad 3 is installed on the outside of the speaker housing 1, that is, the outer side of the speaker is protected by the protective pad 3. When the device falls and one side of the support block 55 falls to the ground, the first shock-absorbing spring 54 cooperates with the damper 44 to achieve a shock-absorbing effect. The internal structure of the speaker is arranged on the mounting groove 41, and the bottom insulating pad 4 insulates it. When the bump occurs and vibration occurs, the mounting plate 5 is installed on the internal structure of the speaker through the spring 51, and the slider 53 slides in the slide tube 52 to keep the mounting plate 5 stable, and the internal structure is protected by the upper protective member 43. The second shock-absorbing spring 42 cooperates with the internal damper 44 to achieve a shock-absorbing effect.

[0035] The shock-absorbing design can effectively overcome the deformation of the internal parts of the CD movement caused by falling. It can also effectively overcome the influence of the cabinet vibration on the movement's disc reading ability when playing music at a high volume, thus avoiding the problem of abnormal CD reading when playing at a high volume.
