[0018] 3. The special effects sound equipment used for the music performance optimizes the sound effect and ensures safety.

[0024] In the present invention, in order to make the light vibrate adaptively following the rhythm of music, a speaker mask 2 is installed on the front of the box 1 of this case, which has the functions of dust protection, acoustic optimization and aesthetics. A reserved hole is opened on the speaker mask 2. The special effect part 3 of this case includes a magnet 31, a pole piece 32 is installed on one side of the magnet 31, and a speaker 33 is installed on the other side of the magnet 31. The speaker 33 is installed on the inner wall of the reserved hole. The special effect part 3 also includes a pole piece 32, an inner column is integrally connected to the pole piece 32, and the inner column extends to the inner circle of the magnet 31. The outer wall of the inner column of the pole piece 32 is slidingly sleeved with a voice coil 34, and the outer wall of the voice coil 34 is wound with a copper winding 35. The magnetic field drives the voice coil 34 to move back and forth through the copper winding 35. The pins of the copper winding 35 are electrically connected to the audio speaker, and one side of the outer wall of the voice coil 34 is fixedly connected to the diaphragm of the speaker 33. The current drives the voice coil 34 to pull the diaphragm and synchronously pull the speaker through the magnetic field, and the cone converts the movement of the voice coil 34 into propagating air waves, prompting the speaker to pull The moving air molecules produce sound, and six connecting rods 36 are symmetrically connected to the other side of the outer wall of the voice coil 34. The six connecting rods 36 all slide through the magnetic pole piece 32 and extend. The extended ends of the six connecting rods 36 are fixedly connected to the cooperative circle 37. The six connecting rods 36 move synchronously with the moving frequency of the voice coil 34. Six lamp holders 38 are symmetrically installed on the outer wall of the cooperative circle 37. The inner walls of the six lamp holders 38 are plugged with spotlights 39. The cooperative circle 37 drives the spotlights 39 to move with the moving frequency of the connecting rod 36. The inner wall of the cooperative circle 37 is fixedly connected with a detection plate 310. The detection plate 310 repeatedly changes the distance with the laser displacement sensor 63 through the moving frequency of the cooperative circle 37. Through holes are symmetrically opened on both sides of the outer wall of the box 1. A lampshade 4 is installed on the inner wall of each through hole. The two lampshades 4 are both made of transparent materials. Every three spotlights 39 on the same side of the cooperative circle 37 are aligned with the lampshade 4 on the same side, and the spotlights 39 project light through the lampshade 4 to the outside of the box 1 to generate light.

[0025] In this embodiment, in order to further synchronize the voice coil 34 with the frequency through mechanical movement, the frequency modulation unit 5 of this case includes a cover 51, which is fixedly connected to the upper back of the inner wall of the box 1. A motor 52 is installed on the inner wall of the cover 51. The cover 51 is used to isolate the motor 52 to avoid magnetic field interference inside the box 1. A rotating rod 53 is fixedly connected to the output shaft of the motor 52. The rotating rod 53 movably penetrates the cover 51 and extends downward. The extended end of the rotating rod 53 is rotatably connected to the bottom of the inner wall of the box 1, and the extended end of the rotating rod 53 is externally The wall eccentric sleeve is provided with six eccentric discs 54, among which the angles between three eccentric discs 54 are all 120 degrees and they are located at the upper part of the extended end of the rotating rod 53, and the angles between the other three eccentric discs 54 are all 120 degrees and they are located at the lower part of the extended end of the rotating rod 53. A box opening is provided on the top of the box body 1, and a box cover 8 is hinged on the inner wall of the box opening. The box cover 8 covers the cover opening of the hood 51, and heat dissipation holes 9 are provided on the box cover 8. The heat dissipation holes 9 are aligned with the motor 52, and the heat dissipation holes 9 are used to discharge the heat generated by the continuous operation of the motor 52.

[0026] It is worth noting that the rotation speed of the motor 52 is synchronously controlled by detecting the moving frequency of the voice coil 34. In this case, the detection part 6 includes a protective cover 61. There are two protective covers 61. The protective covers 61 are used for wiring and protection. The two protective covers 61 are symmetrically installed on the back of the inner wall of the box body 1. The two protective covers 61 are fixedly connected with a mounting plate 62. The mounting plate 62 is installed with a laser displacement sensor 63. The model is SICK-LMS511, which is used to judge the variable pitch frequency of the detection plate 310 in real time and send an electrical signal. The laser displacement sensor 63 is electrically connected to the motor 52 and uses the electrical signal to control the rotation speed of the motor 52. The laser displacement sensor 63 is aligned with the detection plate 310, and the extended end of the rotating rod 53 is centrally arranged between the two protective covers 61.

[0027] It is worth noting that, in order to further mechanically control the color change of the spotlight 39 according to the moving frequency of the voice coil 34, the color changing part 7 of the present case includes a support rod 1 71, a support rod 2 72 and a support rod 3 73, and the number of the support rod 1 71, the support rod 2 72 and the support rod 3 73 is four, and the ends of the four support rods 1 71, the support rod 2 72 and the support rod 3 73 are fixedly connected to the back of the inner wall of the box body 1, and each support rod 1 71 and its adjacent support rods 2 72 and 3 73 are located on the same axis, and the other ends of the four support rods 1 71 are fixedly connected with a magnetic conductive ring 74, adopting Permalloy is used, which has extremely high magnetic permeability and can efficiently guide the external interference magnetic field to bypass the sensitive components inside the speaker 33, greatly reducing the impact of the external magnetic field on the speaker 33. The other end of the four support rods 2 72 is fixedly connected with an absorbing ring 75. The use of ferrite absorbing material can convert the energy of external interference electromagnetic waves into other forms of energy such as heat energy and consume it, and has a good absorption effect on low-frequency and high-frequency interference electromagnetic waves. The other end of the four support rods 3 73 is fixedly connected with a shielding ring 76, which is a copper material with good conductive properties. According to the corrugated board The law of the second embodiment is that when there is a changing current in the outside world that generates an interfering magnetic field, the copper shielding ring 76 will generate an induced current, thereby offsetting part of the interfering magnetic field and playing a shielding role. The sliding sleeves on the four support rods 1 71 are provided with a dynamic ring 1 77, the sliding sleeves on the four support rods 2 72 are provided with a dynamic ring 2 78, and the sliding sleeves on the four support rods 3 73 are provided with a dynamic ring 3 79. Six RGB boards 710 are symmetrically installed on the dynamic ring 1 77, the dynamic ring 2 78 and the dynamic ring 3 79. The RGB full-color light board is used to achieve the effect of RGB three-color transition. The dynamic ring 1 77, the dynamic ring 2 The dynamic ring 78 and the dynamic ring three 79 are elastically connected to the inner wall of the box body 1 with a tension spring 711. The tension spring 711 can reset the connected dynamic ring 1 77, dynamic ring 2 78 and dynamic ring three 79 through the elastic reset feature. The number of tension springs 711 corresponds one-to-one to the four support rods 1 71, support rod 2 72 and support rod 3 73. The angles and axes of the RGB boards 710 on the same side of the dynamic rings 1 77, dynamic ring 2 78 and dynamic ring three 79 correspond one-to-one to the angles and axes of the spotlights 39 on the same side. The light of the spotlights 39 will produce color after passing through the RGB boards 710.

[0028] Working principle: when the speaker plays music with different rhythms, the voice coil 34 moves back and forth through the magnetic field to generate different frequencies. According to this characteristic, the detection plate 310 is connected with the cooperation ring 37 and the connecting rod 36 to move synchronously with the moving frequency of the voice coil 34, so that the moving frequency of the detection plate 310 is monitored in real time by the laser displacement sensor 63, and the electrical signal is fed back to the motor 52 to synchronously control the speed. The motor 52 rotates faster under high-frequency movement and slower under low-frequency movement. The rotating rod 53 repeatedly pushes the corresponding dynamic ring 1 77, dynamic ring 2 78 and dynamic ring 3 79 through fast or slow rotation using the eccentric disk 54, and realizes reciprocating motion under the action of the tension springs 711 connected to each of them. At the same time, the three RGB boards 710 corresponding to each spotlight 39 will also move back and forth, so that the three RGB boards 710 on the same axis form staggered fluctuations, and the spotlight 39 The sound coil 34 will also move back and forth synchronously with the back and forth movement of the voice coil 34, thereby producing an effect of interlaced penetration with the interlaced undulating RGB board 710, realizing a mechanized change in the color emitted by the spotlight 39, avoiding the use of a relatively high-cost laser projector, reducing the cost of use, and not requiring manual programming of complex programs. It also replaces the rigidity and inflexibility of traditional simple lighting presets, and can continuously change colors according to the rhythm of music through mechanical movement changes, thereby improving the special effects atmosphere of the usage scene, and allowing the audience to more intuitively feel the rhythm and emotion of music through audio-visual fusion, enhancing the sense of immersion, while also reflecting the innovation and technological sense of the audio, helping to shape the brand image and attracting people's attention. The magnetic conductive ring 74, the wave absorbing ring 75 and the shielding ring 76 are arranged in a ring around the outside of the magnet 31, helping to cooperate with each other to reduce the interference of external current on the audio speaker 33, and at the same time reduce the mutual interference between the internal current and magnetic field, thereby improving the sound quality and safety, and ensuring the performance effect.
