[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 - Figure 4This utility model provides a multimedia active audio controller, including a controller body 1. Multiple adjustment slots 11 are parallel to each other on the top surface of the controller body 1, and are equidistant from each other along the side of the controller body 1. Adjustment knobs 12 are slidably installed inside each adjustment slot 11. A roller groove 13 is formed on the bottom surface of the controller body 1, perpendicular to the adjustment slots 11. A roller guide rod 2 is mounted inside the roller groove 13 via a bracket. Multiple adjustment knobs 12 are fitted onto the outer wall of the roller guide rod 2. Each winding sleeve 3 has its contact ends connected by bearings. A shielding strip 31 is wound around the outside of each winding sleeve 3. One end of the shielding strip 31 is fixedly connected to the outside of the adjusting knob 12. Multiple limiting baffles 4 are fixedly connected parallel to the top surface of the controller body 1. Strip-shaped slots 41 are provided between adjacent sides of the multiple limiting baffles 4. Two adjacent strip-shaped slots 41 respectively engage with the two sides of the shielding strip 31. A scale strip 42 is provided on the top surface of the limiting baffles 4. The adjusting knob 12 is slidably mounted and adjusted... Within the groove 11, the various factors affecting sound production are precisely controlled by adjusting its movement. During the movement of the adjustment knob 12, it can be compared with the scale bar 42. The roller guide rod 2 is installed on the controller body 1 via the roller groove 13, and the take-up sleeve 3 is fitted between the outer walls of the roller guide rod 2. The bearing surfaces of each take-up sleeve 3 contact each other, allowing for relative rotation without interference. This ensures that during the movement of the adjustment knob 12, the blocking strip 31 fixed to its side wall can... Under the restriction of the strip groove 41 on the side wall of the limiting baffle 4, the winding sleeve 3 of it is driven to rotate, and the winding sleeve 3 is used to wind up and unwind the shielding strip 31. The winding sleeve 3 does not have a driving force for the rotation and winding up of the shielding strip 31, and does not hinder the movement of the adjustment knob 12. When the controller body 1 is not working, the shielding strip 31 can slide the adjustment knob 12 to the limit away from the adjustment groove 11, and completely block the upper opening of the adjustment groove 11 to prevent dust from entering the device through the adjustment groove 11.

[0026] like Figure 1 As shown, a limiting bracket 14 is fixedly connected to the center of the side of the adjustment knob 12 away from the roller guide rod 2. A limiting component 5 is provided on the top surface of the controller body 1 near one edge of the multiple adjustment slots 11. When the controller body 1 is not in use, the adjustment knob 12 and the limiting component 5 cooperate with each other to mechanically limit the blocking strip 31 to block the adjustment slot 11, preventing the blocking strip 31 from being pushed to roll up and expose the adjustment slot 11 after the adjustment knob 12 is accidentally touched.

[0027] like Figure 1 and Figure 3As shown, the limiting component 5 includes a lifting circular plate 51. The lifting circular plate 51 has symmetrically arranged mounting slots 52 on both sides. Mounting brackets 53 are slidably installed inside each of the two mounting slots 52. The bottom of the mounting brackets 53 is vertically fixed to the top surface of the controller body 1. A sloping protrusion 54 is vertically fixed to the center of the top surface of the lifting circular plate 51, with the sloping surface of the protrusion 54 facing the limiting bracket 14. A spring 55 is vertically fixed to the center of the bottom surface of the lifting circular plate 51, with one end of the spring 55 vertically fixed to the top surface of the controller body 1. The limiting component 5 is connected to the mounting brackets 53 and the mounting slots 52 through mutual... When the controller body 1 is installed on the lifting circular plate 51, when the blocking strip 31 needs to completely block the adjusting groove 11, the roller groove 13 is pushed closer to the position of the limiting component 5. During this process, the limiting bracket 14 first contacts the inclined surface of the inclined protrusion 54 on the lifting circular plate 51, and gradually overcomes the elastic force of the spring 55. When the through hole on the limiting bracket 14 moves to the top of the inclined protrusion 54, the inclined protrusion 54 is reset under the elastic force of the spring 55 and its position is limited by the mutual engagement between its outer wall and the through hole of the limiting bracket 14.

[0028] Working principle: The adjustment knob 12 is slidably installed in the adjustment groove 11, and its movement controls various factors of sound production. During the movement of the adjustment knob 12, it can be compared with the scale bar 42. The roller guide rod 2 is installed on the controller body 1 through the roller groove 13, and the take-up sleeve 3 is fitted between the outer walls of the roller guide rod 2. The bearing surfaces of each take-up sleeve 3 contact each other, allowing them to rotate relative to each other without interference. Thus, during the movement of the adjustment knob 12, the blocking strip 31 fixed to its side wall can drive the rotation of its corresponding take-up sleeve 3 under the restriction of the strip-shaped slot 41 on the side wall of the limiting baffle 4, achieving the winding and unwinding of the blocking strip 31. The winding and unwinding of the blocking strip 31 itself does not have a driving force and does not obstruct the movement of the adjustment knob 12. When the controller body 1 is not in operation, the blocking strip 31 can slide the adjustment knob 12 to its limit away from the adjustment groove 11, and its upper part of the adjustment groove 11... The square opening is completely covered to prevent dust from entering the device through the adjustment slot 11. When the controller body 1 is not in use, the adjustment knob 12 and the limiting component 5 cooperate to mechanically limit the blocking strip 31 to cover the adjustment slot 11, preventing accidental activation of the adjustment knob 12 and subsequent retraction of the blocking strip 31 to expose the adjustment slot 11. The limiting component 5, through the cooperation of the mounting bracket 53 and the locking slot 52, allows the controller body 1 to mount the lifting disc 51. When the blocking strip 31 completely blocks the adjusting groove 11, the roller groove 13 is pushed closer to the position of the limiting component 5. During this process, the limiting bracket 14 first contacts the inclined surface of the inclined protrusion 54 on the lifting circular plate 51, and gradually overcomes the elastic force of the spring 55 under the pushing. When the through hole on the limiting bracket 14 moves to directly above the inclined protrusion 54, the inclined protrusion 54 is reset under the elastic force of the spring 55 and its position is limited by the mutual engagement between its outer wall and the through hole of the limiting bracket 14.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
