Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a transparent screen speaker box. Background Technology

[0002] Traditional speakers often use coplanar high and low frequency drivers, which are prone to sound wave interference and lack visual interactive features. Some products with lighting effects have the following drawbacks: lighting issues: direct LED light causes glare, and uneven scattering results in poor halo layering; acoustic defects: vibration of the low frequency driver can easily cause cabinet resonance, affecting high-frequency clarity; structural limitations: low cabinet space utilization makes it difficult to balance portability and acoustic performance. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a transparent screen speaker with a compact structure, high space utilization, and synergistic improvement of sound and light performance.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a transparent screen speaker, including a hollow cylindrical speaker bracket, a sound-generating device disposed on the upper end of the speaker bracket, a light-emitting device disposed on the outer wall of the speaker bracket, and a battery. The sound-generating device includes a speaker bracket disposed on the upper end of the speaker bracket, a tweeter fixed on the speaker bracket and facing upward, and a woofer fixed on the speaker bracket and located below the tweeter. The woofer is facing upward and is disposed inside the upper end of the speaker bracket. The light-emitting device includes, from the inside out, a light-emitting unit, a light shield, and a light-emitting cover. The light-emitting unit includes a plurality of LED beads, and the light shield has a plurality of light-emitting holes corresponding to the LED beads. The principle of this invention: The hollow speaker bracket forms a sealed acoustic cavity inside, with the outside serving as a light carrier; the tweeter is fixed to the top of the speaker bracket, radiating high-frequency sound waves upwards; the woofer is built into the upper cavity of the bracket, vibrating upwards and guided by the cavity to enhance low-frequency diffusion; the tweeter and woofer are layered vertically, and the sound wave path is isolated by the cavity partition to reduce mutual interference; multiple LED beads are arranged in a ring array along the outer wall of the bracket, forming 360° light emission, which, in conjunction with the musical rhythm, forms a visible light column, achieving a harmonious combination of sound and light; the light shield enables directional light output and reduces light leakage.

[0005] As an improvement, the speaker bracket is provided with a top cover, the top cover has a sound outlet in the middle, and the sound outlet is provided with a mesh cover.

[0006] As an improvement, the lower end of the speaker bracket is provided with a bottom cover, the bottom cover has a through hole in the middle, and a passive plate is provided at the through hole.

[0007] As an improvement, the light-emitting unit includes several vertically arranged light strips, each light strip including an LED substrate and several LED beads that are closely attached to the outer wall of the speaker bracket, and the LED beads of the light-emitting unit are arranged in a ring array.

[0008] As an improvement, the light-emitting cover includes a transparent cover body that is fitted over the light-shielding cover and a black outer shell that is fitted over the transparent cover body.

[0009] As an improvement, the light-emitting cover is equipped with function buttons and a charging interface.

[0010] The beneficial effects of this utility model compared with the prior art are:

[0011] 1. The hollow speaker bracket forms a sealed acoustic cavity inside, while the outside serves as a light carrier;

[0012] 2. The tweeter is fixed to the top of the speaker bracket and radiates high-frequency sound waves upwards. The woofer is built into the upper cavity of the bracket, vibrates upwards, and is guided by the cavity to enhance low-frequency diffusion. The tweeter and woofer are layered and the sound wave path is isolated by the cavity partition to reduce mutual interference.

[0013] 3. Multiple LED beads are arranged in a circular array along the outer wall of the bracket to form 360° light emission, which, in conjunction with the rhythm, forms a visible light column, creating a harmonious combination of sound and light;

[0014] 4. The light shield directs light in a specific direction, reducing light leakage. Attached Figure Description

[0016] Figure 2 This is an exploded view of the present invention. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 , 2 As shown, a transparent speaker includes a hollow cylindrical speaker bracket 9, a sound-generating device located at the upper end of the speaker bracket 9, a light-emitting device located on the outer wall of the speaker bracket 9, and a battery 10. The battery 10 is located inside the lower end of the speaker bracket 9, and supplies power to the sound-generating device and the light-emitting device. The battery 10 also lowers the center of gravity of the speaker, making it less prone to tipping over. The lower end of the speaker bracket 9 has a bottom cover 12, and the bottom cover 12 has a through hole in the middle, with a passive plate 11 located at the through hole.

[0019] like Figure 1 , 2As shown, the sound-generating device includes a speaker bracket 4 mounted on the upper end of a speaker cabinet 9, a tweeter 2 fixed to the speaker bracket 4 and facing upwards, and a woofer 5 fixed to the speaker bracket 4 and located below the tweeter 2. The speaker bracket 4 is annular, and the tweeter 2 is located in the middle of the speaker bracket 4. The speaker bracket 4 has a top cover 3, which serves as a decorative cover. The top cover 3 is connected to the speaker bracket 4 by screws or clips. The top cover 3 has a sound outlet in the middle, and a mesh cover 1 is provided at the sound outlet. The tweeter 2 faces the mesh cover 1. The woofer 5 is positioned upwards and is located inside the upper end of the speaker cabinet 9. The tweeter 2 is fixed to the top of the speaker bracket 4 and radiates high-frequency sound waves upwards. The woofer 5 is built into the upper cavity of the bracket, vibrates upwards, and enhances low-frequency diffusion through cavity guidance. The tweeter and woofer 5 are layered, and the sound wave paths are isolated by cavity partitions to reduce mutual interference.

[0020] like Figure 1 , 2 As shown, the light-emitting device includes, from the inside out, a light-emitting unit, a light-shielding cover 6, and a light-emitting cover. The light-emitting unit includes several LED beads 15. In this embodiment, the light-emitting unit includes several vertically arranged light strips, each light strip comprising an LED substrate closely attached to the outer wall of the speaker bracket 9 and several LED beads 15. The LED beads 15 of the light-emitting unit are arranged in a ring array. The light-shielding cover 6 has several light-emitting holes corresponding to the LED beads 15, enabling directional light output and reducing light crosstalk. The light-emitting cover includes a transparent cover 7 fitted over the light-shielding cover 6 and a black outer shell 8 fitted over the transparent cover 7. The light from the LED beads 15 is directionally emitted through the light-shielding cover 6, passing through the transparent cover 7 to form a ring of light. The black outer shell 8 gives the light a floating visual effect in a dark environment, forming a visible light column in conjunction with the music, achieving a harmonious combination of sound and light. The light-emitting cover is equipped with a function button 13 and a charging interface 14. The function button 13 controls the sound-emitting device and the light-emitting device, and the charging interface 14 charges the battery 10.
