[0002] Speakers are devices that output sound and have a wide range of applications. With technological advancements and rising living standards, the demand for audio performance is growing. Speakers that simply output sound are no longer sufficient. Vacuum tube amplifiers offer a warm, sweet tone, making music more enjoyable and less jarring. Most transistor amplifiers, by contrast, tend to sound cold and harsh. Therefore, integrated speakers that combine vacuum tubes and Bluetooth better meet the demands for both sound quality and convenience.

[0003] Currently, speakers on the market often have grilles or holes in the housing to allow sound to radiate from the speakers. However, when the speakers are not in use, dust can easily enter the speakers through the grilles or holes. Therefore, a vacuum tube Bluetooth integrated speaker is provided to address this issue.

[0025] Please refer to Figures 1-6 The utility model comprises a vacuum tube Bluetooth integrated speaker, comprising: an audio body 1, a speaker 2 is arranged inside the front of the audio body 1, a protective plate 3 is fixedly connected to the audio body 1 on one side of the speaker 2, the protective plate 3 is longitudinally fitted and slidably connected to the dustproof plate 4 on one side of the speaker 2, a first through hole 13 is opened on the side of the protective plate 3 corresponding to the speaker 2, a second through hole 14 is opened on the side of the dustproof plate 4 facing the first through hole 13, a limiting groove 7 is opened on one side of the middle of the upper end of the protective plate 3, and slide grooves 8 are symmetrically opened on the left and right sides of the limiting groove 7, and a positioning block 9 is slidably connected to the limiting groove 7 through the slide groove 8.

[0026] Combine Figure 5 and Figure 6 As shown, the positioning block 9 is a convex structure, and the positioning block 9 is provided with a corrugated tooth opening 10 on one side of the slide groove 8. The inner side of the slide groove 8 is provided with a corrugated structure opposite to the corrugated tooth opening 10, so that the corrugated tooth opening 10 on the positioning block 9 can be engaged with the corrugated structure inside the slide groove 8 under the elastic force of the spring 12, thereby effectively preventing the positioning block 9 from automatically moving at will. The positioning block 9 is located at one end of the dustproof plate 4 and is slidably sleeved with a round rod 11. The outer side of the circumference of the round rod 11 is sleeved with a spring 12. The connection between the dustproof plate 4 and the positioning block 9 can be achieved through the round rod 11. The round rod 11 is fixedly connected to the dustproof plate 4 at the opposite end of the positioning block 9. Figure 3 and Figure 4 As shown, there are several first through holes 13 and several second through holes 14, and the inner diameters and spacing distances of the several first through holes 13 and the second through holes 14 are the same, so as to facilitate the up and down movement of the dustproof plate 4, so that the first through holes 13 and the second through holes 14 can be staggered or aligned with each other.

[0027] Among them, the protective plate 3 is provided with a guide groove 5 at one end of the dustproof plate 4, and a guide bar 6 is provided on the outside of the dustproof plate 4 facing the guide groove 5, so as to ensure that the dustproof plate 4 fits on the side of the protective plate 3 and moves up and down, and the inside of the guide groove 5 fits and slides in the guide bar 6, and the guide bar 6 and the guide groove 5 are both trapezoidal structures. An adjustment knob 15 is provided on one side of the upper end of the audio body 1, and a handle 16 is provided on one side of the top of the audio body 1. A display screen 19 is provided on the upper end of the audio body 1 on the side of the adjustment knob 15, and an externally threaded rod 17 is fixedly connected to the corner of the bottom end of the audio body 1, and the bottom end of the externally threaded rod 17 is threadedly connected to a support seat 18, and an anti-slip pad is provided at the bottom end of the support seat 18, and then by rotating the support seat 18 on the externally threaded rod 17, the height of the support seat 18 can be adjusted, thereby facilitating the adjustment of the stability of the audio body 1.

[0028] Reference Figure 2 A mounting groove 20 is provided inside the upper end of the speaker body 1, and a vacuum tube 21 is installed inside the mounting groove 20. A sound outlet 22 is provided on the top of the mounting groove 20. A transparent glass cover is provided at the front end of the mounting groove 20, which is convenient for viewing the internal vacuum tube 21 and more beautiful. A Bluetooth module is integrated inside the speaker body 1, and it is more convenient to use the speaker via Bluetooth. The speaker 2 in the speaker body 1 is combined with the vacuum tube 21 to form an integrated speaker. The vacuum tube 21 amplifier has a warm and sweet tone, and the music played is more pleasant to listen to and not harsh. Relatively speaking, the tone of most transistor amplifiers is cold and hard, and the combination with the speaker body 1 can further improve the sound quality.

[0029] Specifically, when the present invention is in use, the positioning block 9 can be manually pressed and pushed upward, and then the positioning block 9 can be moved upward together with the dustproof plate 4 through the round rod 11, so that the second through hole 14 on the dustproof plate 4 is opposite to the first through hole 13, and the positioning block 9 can be stopped from being pressed, and then the positioning block 9 can be pushed in the opposite direction under the elastic force of the spring 12, so that the corrugated tooth mouth 10 on the positioning block 9 is engaged with the inner wall of the slide groove 8, so that the dustproof plate 4 can be limited and fixed, and the sound can be played through the speaker 2. After use, the positioning block 9 can be pressed downward in the same way, so that the second through hole 14 and the first through hole 13 are misaligned with each other, and the speaker 2 on the audio body 1 can be sealed, thereby effectively preventing external dust from entering.
