[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1-8A lyric speaker comprises a glass panel 1 and a rear shell 16. An inner cavity is provided between the glass panel 1 and the rear shell 16. The inner cavity is divided into a sound-emitting area and a display area. A piezoelectric ceramic 4 and a main circuit board 11 are installed inside the sound-emitting area. The piezoelectric ceramic 4 is connected to the lower side of the glass panel 1 and is electrically connected to the main circuit board 11. Two groups of first concave structures 17 and second concave structures 18 with "concave" cross-sections are respectively provided on the glass panel 1 and the rear shell 16. The protrusions on the inner sides of the first concave structure 17 and the second concave structure 18 are opposite and have opposite magnetic properties. A light strip board 2 is provided in the display area. A light-emitting device is provided on the light strip board 2. The light-emitting device is electrically connected to the main circuit board 11. A winding group bracket 10 is rigidly fixed below the light strip board 2. The outside of the winding group bracket 10 is tightly wound with copper Coil 6, the copper coil 6 is electrically connected to the main circuit board 11, and the main circuit board 11 outputs forward or reverse current to the copper coil 6. The current vertically passes through the magnetic lines of force between the first concave structure 17 and the second concave structure 18. Silent bearings 7 are sleeved on both ends of the winding group bracket 10. The silent bearings 7 can roll in the concave parts of the first concave structure 17 and the second concave structure 18. A speed measuring device is provided in the display area. The speed measuring device is used to detect the speed of the light strip board 2. A control unit is provided on the main circuit board 11. The control unit can adjust the current applied to the copper coil 6 according to the measurement results of the speed measuring device. A rechargeable lithium battery 13 is electrically connected to the bottom of the main circuit board 11. The main circuit board 11 is provided with a TYPE-C socket 12 and a wireless transmission module that can be used for power supply and audio playback.

[0027] Reference Figure 2 The piezoelectric ceramic 4 is tightly fixed to the underside of the glass panel 1 and electrically connected to the main circuit board 11. Audio playback can be performed through the Type-C socket 12 or the wireless transmission module provided on the main circuit board 11. The piezoelectric ceramic 4 thus transforms the entire glass panel 1 into a giant speaker, creating a vast sound field that not only delivers high-quality sound but also an immersive listening experience. Furthermore, the piezoelectric ceramic 4 is compact and thin, taking up little space whether stacked or laid flat, making large-screen, even full-screen, and ultra-thin speakers possible.

[0028] The speed measuring device includes several groups of Hall switches 8 symmetrically arranged in pairs. The protruding parts on the outer sides of the two second concave structures 18 are symmetrically provided with several mounting grooves, and a Hall switch 8 is installed in each mounting groove. Every two relative Hall switches 8 are used to detect different movement positions and states of the light strip board 2. The protruding part on the outer side of the first concave structure 17 is provided with a first boss 31 that matches the position and number of the mounting grooves. The first boss 31 is used to fix the Hall switch 8 in the mounting groove. By setting the Hall switch 8, the speed of the light strip board 2 in the reciprocating motion can be controlled to improve the display effect.

[0029] The first concave structure 17 includes a middle frame 3, an installation groove is provided on the inner side of the middle frame 3, an N-pole magnetic strip 5 is installed in the installation groove, a protrusion is provided on the outer side of the middle frame 3, and an upper track 33 is opened between the installation groove and the protrusion. The second concave structure 18 includes a second-order connecting edge structure 181, the second-order connecting edge structure 181 is integrally formed with the rear shell 16, an S-pole magnetic strip 9 is installed on the inner side of the second-order connecting edge structure 181, a lower track 161 is provided on the first-step surface of the second-step connecting edge structure 181, and the second step of the second-step connecting edge structure 181 protrudes from the first step.

[0030] The circumferential direction of the silent bearing 7 is slidably connected to the upper track 33 and the lower track 161, ensuring that the silent bearing 7 can only roll linearly between the upper track 33 and the lower track 161. By setting the middle frame 3 and the second-order connecting edge structure 181 integrally formed with the rear shell 16, it is convenient for assembly and maintenance and the silent bearing 7 is restricted to sliding between the upper track 33 and the lower track 161. When the friction of the silent bearing 7 becomes larger, it is only necessary to disassemble the glass panel 1 and the middle frame 3 in turn to remove the silent bearing 7. The silent bearing 7 does not directly contact the glass panel 1, which can avoid wear on the glass panel 1.

[0031] The copper coil 6 crosses the middle of the two pairs of N-pole magnetic strips 5 and S-pole magnetic strips 9 on the left and right sides, and is electrically connected to the main circuit board 11. The main circuit board 11 is electrically connected to the rechargeable lithium battery 13. The main circuit board 11 outputs a forward or reverse current to the copper coil 6, and the current vertically passes through the magnetic lines of force between the N-pole magnetic strip 5 and the S-pole magnetic strip 9. Due to the action of the Ampere force, the copper coil 6, the winding group bracket 10 and the silent bearing 7 drive the light strip board 2 to move horizontally forward or backward at high speed and at a variable speed or at a constant speed, and use the visual persistence effect to output lyrics or subtitles. The dynamic special effects subtitles unique to the full-color LED light strip and the clear and sharp full-color lights convey the lyrics, atmosphere lighting effects, and artistic conception; bringing a lyrics speaker that is different from the existing stereotyped electronic display screens.

[0032] The lower ends of the upper rail 33 and the lower rail 161 and the top edge of the rechargeable lithium battery 13 are both provided with anti-collision strips 15, and the back of the middle frame 3 is provided with a second boss 32, which is used to fix the anti-collision strips 15 at the lower ends of the upper rail 33 and the lower rail 161.

[0033] The display area is equipped with an ambient light panel 14, which features a top-lit full-color LED array 141 and a side-lit full-color LED array 142. Connected to the rear housing 16, the panel 14 provides background lighting, ambient lighting, and dynamic lighting effects through the strobing of the top-lit full-color LED array 141 and the side-lit full-color LED array 142. These arrays not only enhance the immersive experience of indirect background lighting but also enhance the sharpness and visual impact of direct lighting. This not only elevates the speaker's aesthetics but also delivers a more engaging, engaging, and immersive listening experience.

[0034] The light-emitting device includes a first row of full-color LED light columns 21 and a second row of full-color LED light columns 22 arranged along the length direction of the light strip board 2. Through the strobing of the first row of full-color LED light columns 21 and the second row of full-color LED light columns 22, the output of lyrics subtitles, dynamic special effect words and dynamic patterns is achieved due to the visual persistence effect.

[0035] The first row of full-color LED arrays 21 and the second row of full-color LED arrays 22 are staggered. By continuously increasing the horizontal density of LED beads between the first and second rows of full-color LED arrays 21 and 22, display accuracy is continuously improved. Furthermore, the reciprocating linear motion of the light strip 2 allows lyrics, subtitles, dynamic special effects, and dynamic patterns to scroll up and down the screen, which is more in line with human reading habits and easier to use.

[0036] Reference Figure 5 There are four groups of Hall switches 8 arranged in sequence from bottom to top.

[0037] Working principle:

[0038] According to the Ampere force formula: F = ILBsinα, B represents the magnetic induction intensity, which indicates the magnitude of the magnetic field strength, and is measured in Teslas; I represents the current intensity, which is the amount of charge passing through a certain cross-section of the wire per unit time, and is measured in amperes; L represents the effective length of the wire in the magnetic field, which is the length of the wire that is exposed to the magnetic field, and is measured in meters; F represents the magnitude of the Ampere force exerted on the wire in the magnetic field, and is measured in Newtons; and α represents the angle between the direction of the current I and the direction of the magnetic field B. Since the angle between the direction of the current I and the direction of the magnetic field B is 90° in this case, sinα = sin90° = 1; and since the magnetic induction intensity B and the effective length of the wire L in the magnetic field are fixed in this case, the Ampere force F is positively correlated with the current intensity I. When the current intensity I increases, the Ampere force F also increases; when the current intensity I decreases, the Ampere force F also decreases.

[0039] By setting the positions of 4 groups of 8 Hall switches 8 on the rear housing 16, the speed of the light strip board 2 in the back and forth reciprocating motion can be controlled. The specific implementation steps are:

[0040] Step 1: When the main circuit board 11 detects that the copper coil 6 is at the position of the first row of Hall switches 8, the speed of the light strip board 2 is 0;

[0041] Step 2: When the light strip board 2 moves from the position of the first row of Hall switches 8 to the position of the second row of Hall switches 8, the main circuit board 11 applies a larger current to the copper coil 6, thereby rapidly increasing the displacement speed of the light strip board 2, and the displacement speed changes from 0 to the maximum displacement speed Vmax;

[0042] Step 3: When the main circuit board 11 captures the position of the copper coil 6 at the position of the second row of Hall switches 8, the speed of the light strip board 2 remains constant at the maximum displacement speed Vmax;

[0043] Step 4: When the light strip board 2 moves from the position of the second row of Hall switches 8 to the position of the third row of Hall switches 8, the main circuit board 11 applies a constant current to the copper coil 6, thereby keeping the light strip board 2 constant at the maximum displacement speed Vmax;

[0044] Step 5: When the main circuit board 11 detects that the copper coil 6 is located at the position of the third row of Hall switches 8, the speed of the light strip board 2 remains constant at the maximum displacement speed Vmax;

[0045] Step 6: When the light strip board 2 moves from the position of the third row of Hall switches 8 to the position of the fourth row of Hall switches 8, the main circuit board 11 will apply a decreasing current to the copper coil 6, thereby rapidly reducing the displacement speed of the light strip board 2, and the displacement speed changes from the maximum displacement speed Vmax to the minimum displacement speed 0;

[0046] Step 7: When the main circuit board 11 detects that the copper coil 6 is located at the position of the fourth row of Hall switches 8, the speed of the light strip board 2 is 0; at the same time, the reverse current is switched to achieve the backward displacement of the light strip board 2;

[0047] Step 8: When the light strip board 2 moves from the position of the fourth row of Hall switches 8 to the position of the third row of Hall switches 8, the main circuit board 11 applies a larger current to the copper coil 6, thereby rapidly increasing the displacement speed of the light strip board 2, and the displacement speed changes from 0 to the maximum displacement speed Vmax;

[0048] Step 9: When the main circuit board 11 detects that the copper coil 6 is located at the position of the third row of Hall switches 8, the speed of the light strip board 2 remains constant at the maximum displacement speed Vmax;

[0049] Step 10: When the light strip board 2 moves from the position of the third row of Hall switches 8 to the position of the second row of Hall switches 8, the main circuit board 11 applies a constant current to the copper coil 6, thereby keeping the light strip board 2 constant at the maximum displacement speed Vmax;

[0050] Step 11: When the main circuit board 11 captures the position of the copper coil 6 at the position of the second row of Hall switches 8, the speed of the light strip board 2 remains constant at the maximum displacement speed Vmax;

[0051] Step 12: When the light strip board 2 moves from the position of the second row of Hall switches 8 to the position of the first row of Hall switches 8, the main circuit board 11 applies a decreasing current to the copper coil 6, thereby rapidly reducing the displacement speed of the light strip board 2, and the displacement speed changes from the maximum displacement speed Vmax to the minimum displacement speed 0;

[0052] Step 13: When the main circuit board 11 detects that the copper coil 6 is located at the first row of Hall switches 8, the speed of the light strip board 2 is reduced to 0. At the same time, the forward current is switched back to enable the light strip board 2 to move forward. This cycle is repeated until the light strip board 2 stops. Finally, the light strip board 2 stops at the first row of Hall switches 8.

[0053] By rapidly moving the light strip 2 back and forth, and controlling the strobing of the first and second rows of full-color LED light arrays 21 and 22, the display of lyrics, subtitles, dynamic special effects, and dynamic patterns is achieved through the persistence of vision effect. The staggered arrangement of the first and second rows of full-color LED light arrays 21 and 22 continuously increases the horizontal density of LED beads on the light strip 2, further improving display accuracy. Furthermore, the back-and-forth linear motion of the light strip 2 allows for the display of lyrics, subtitles, dynamic special effects, and dynamic patterns, which aligns with human reading habits and is easier to use.

[0054] The strobing of the top-lit full-color LED array 141 and the side-lit full-color LED array 142 on the ambient light panel 14 creates a dynamic lighting experience, including background lighting, ambient lighting, and dynamic lighting effects. These arrays not only enhance the immersive experience of indirect ambient lighting but also sharpen the direct lighting and enhance the visual impact of the lighting's rhythm. This not only elevates the speaker's style but also delivers a more engaging, engaging, and immersive listening experience.
