[0029] 1. A laser lamp assembly is provided. Under normal conditions, the laser lamp assembly is placed horizontally, and the light is emitted horizontally for use. When adjustment is required, the operator toggles the top of the module front shell so that the module front shell drives the rotating ring to rotate on the top of the module pressing piece.

When the speaker assembly is not in use, the screw rod is rotated to drive the movable plate thereon to rise, and the fixed rod limits the movable plate. The rising of the movable plate drives the connecting plate to rise, and the movable plate compresses spring 1, and the connecting plate then drives the protective cloth layer to rise and unfold. The rising of the movable plate also drives the mounting block to rise, and the mounting block drives the gear to move, and the gear is engaged with the rack, so that the gear rotates, thereby causing the push plate to reciprocate. The swing of the squeezing roller will stretch spring two, and spring two assists the resetting of the squeezing roller. The movement of the pushing plate will push the squeezing roller to swing and squeeze the protective cloth layer, which can squeeze the protective cloth layer onto the mesh cover of the front cover, making it easy to clean the mesh cover. Until the moving plate is in contact with the top plate, the unfolding of the protective cloth layer is completed, making it easy for the protective cloth layer to cover the mesh cover, reducing the adhesion of dust on the speaker mesh cover when not in use, playing a protective role, and solving the problem that dust is easily attached to the outer mesh cover when the speaker is not in use. When too much dust accumulates, it is easy to affect the normal use of the sound outlet, and also reduce the sound effect of the speaker. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Embodiment 2: Figure 8-12 As shown, a protective component 4 is provided. When the speaker assembly 1 is in use, the movable plate 44 is located near the bottom plate 3, and the protective cloth layer 47 is in a retracted state, which does not affect the normal use of the speaker assembly 1. When the speaker assembly 1 is not in use, by rotating the screw rod 43, the screw rod 43 drives the movable plate 44 thereon to rise, and the fixed rod 41 limits the movable plate 44. The rising of the movable plate 44 drives the connecting plate 46 to rise, and the movable plate 44 will compress the spring 45, and the connecting plate 46 will then drive the protective cloth layer 47 to rise and unfold. The rising of the movable plate 44 will also drive the mounting block 413 to rise, and the mounting block 413 drives the gear 415 to move, and the gear 415 is engaged with the rack 49, so that the gear 415 rotates.

[0062] Since the annular groove 416 is eccentrically set, the auxiliary rod 418 moves inside the annular groove 416, and the limiting sleeve 421 limits the side plate 417, so that the pushing plate 419 moves back and forth, and the swinging of the squeezing roller 412 will stretch the spring 2 422, and the spring 2 422 assists the resetting of the squeezing roller 412. The movement of the pushing plate 419 will push the squeezing roller 412 to swing and squeeze the protective cloth layer 47, which can squeeze the protective cloth layer 47 onto the mesh cover of the front cover plate 12, so as to facilitate the cleaning of the mesh cover. Until the moving plate 44 is in contact with the top plate 42, the unfolding of the protective cloth layer 47 is completed, so that the protective cloth layer 47 can cover the mesh cover, thereby reducing the adhesion of dust on the speaker mesh cover when not in use, thereby playing a protective role.

[0063] Working principle: When using the device, first, Figure 1-12 As shown, when adjustment is needed, the operator moves the top of the module front shell 21 so that the module front shell 21 drives the rotating ring 27 to rotate on the top of the module pressing piece 26, and the wave groove 28 at the bottom of the rotating ring 27 abuts against the protrusion on the top of the spring piece 210. When the rotating ring 27 rotates, the wave groove 28 squeezes the protrusion of the spring piece 210, so that the rotating ring 27 can be rotated in steps for adjustment.

[0064] The rotation of the rotating ring 27 will also drive the outer limit rod 29 to rotate. The limit rod 29 stops when it rotates to abut against the bottom end of the limit block 212. At this time, it is convenient for the positioning of the module front shell 21 after adjustment. There are two limit rods 29 and limit blocks 212 on both sides. When the limit rod 29 at one end abuts against the limit block 212, the module front shell 21 is in a downward tilted state. When the limit rod 29 at the other end abuts against the limit block 212, the module front shell 21 is in an upward flipped irradiation state.

[0065] When the speaker assembly 1 is in use, the movable plate 44 is located near the bottom plate 3, and the protective cloth layer 47 is in a retracted state, which does not affect the normal use of the speaker assembly 1. When the speaker assembly 1 is not in use, the screw rod 43 is rotated to drive the movable plate 44 thereon to rise, and the fixed rod 41 limits the movable plate 44. The rising of the movable plate 44 drives the connecting plate 46 to rise, and the movable plate 44 will compress the spring 45, and the connecting plate 46 will then drive the protective cloth layer 47 to rise and unfold. The rising of the movable plate 44 will also drive the mounting block 413 to rise.

[0066] The mounting block 413 drives the gear 415 to move, and the gear 415 meshes with the rack 49, so that the gear 415 rotates. Since the annular groove 416 is eccentrically arranged, the auxiliary rod 418 moves inside the annular groove 416, and the limiting sleeve 421 limits the side plate 417, so that the push plate 419 moves back and forth. The swinging of the squeezing roller 412 will stretch the spring 2 422, and the spring 2 422 assists the resetting of the squeezing roller 412.

[0067] The movement of the pushing plate 419 will push the squeezing roller 412 to swing and squeeze the protective cloth layer 47, which can squeeze the protective cloth layer 47 onto the mesh cover of the front cover plate 12, making it easier to clean the mesh cover. Until the moving plate 44 is in contact with the top plate 42, the protective cloth layer 47 is unfolded, making it easier for the protective cloth layer 47 to cover the mesh cover.

[0068] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
