Description

Technical field:

[0001] The present invention relates to the technical field of speaker products, in particular to a lyric speaker with a speaker installed upside down. Background technology:

[0002] Lyrics speakers are a new type of speaker technology developed in recent years. They integrate the sound system and the display screen, so that when playing songs, the lyrics can be displayed on the display screen at the same time, giving users a better experience. For example, when using lyrics speakers for karaoke, the lyrics can also serve as a reminder of the lyrics. In addition, even if the music does not have lyrics, pictures or animations can be displayed on the screen to increase the fun of the product.

[0003] The Chinese utility model patent application number 202421287643.4 discloses a lyrics and subtitles audio system, which includes a cabinet, one end of the interior of the cabinet is connected to a main control board, and the lower end of one side of the cabinet is connected to a speaker assembly, the speaker assembly is used to receive audio signals and process and amplify them, and the interior of the cabinet is connected to a display screen near one end of the speaker assembly. The speaker assembly includes a flat transparent plate, which is encapsulated to one side of the cabinet and is located in front of the display screen, and two speaker devices are connected to both sides of the lower end of the transparent plate, and the two speaker devices are both arranged on the same side of the cabinet.

[0004] Because the speaker assembly is directly mounted on the bottom of the transparent plate, its diaphragm faces forward and is located in front of the display screen. This blocks a portion of the display screen, resulting in an incomplete display and a poor user experience. Alternatively, the lyrics and subtitles speaker needs to be made very high to allow for sufficient space to move the display screen upward, which increases the size of the entire speaker box and affects its usability. Furthermore, because the diaphragm of the speaker assembly faces forward, the speaker assembly bracket, magnet, and other parts are all facing the inner cavity of the box. This causes all the heat generated by the speaker assembly during operation to be discharged into the inner cavity of the box, which affects the heat resistance and display quality of the display screen.

[0005] In view of this, the inventors propose the following technical solutions. Summary of the invention:

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a lyrics speaker box with an inverted mounted speaker.

[0008] Furthermore, in the above technical solution, the front end of the main box has a first mounting opening, the transparent plate is in a flat plate shape, the transparent plate is fixed to the front end of the main box and covers the first mounting opening, and the speaker is arranged at the first mounting hole on the lower end surface of the main box; or, the front end of the main box has a first mounting opening, and the lower end of the main box has a second mounting opening connected to the first mounting opening; the transparent plate is L-shaped, the first plate body at the upper part of the transparent plate is fixed to the front end of the main box and covers the first mounting opening, and the first plate body is located in front of the display screen, the second plate body at the lower part of the transparent plate is fixed to the front end of the main box and covers the second mounting opening, and the speaker is arranged at the second mounting hole of the second plate body.

[0009] Furthermore, in the above technical solution, the angle formed between the first plate and the second plate is 45°-135°, and the first plate and the second plate are connected by an arc-shaped connecting portion.

[0010] Furthermore, in the above technical solution, the speaker is installed inverted in the mounting tube, the lower end of the mounting tube is fixed at the second mounting hole to form a sealed assembly, the outer edge of the diaphragm of the speaker is fixed at the upper end opening of the mounting tube to form a sealed assembly, and the mounting tube is located behind the first plate.

[0011] Furthermore, in the above technical solution, a decorative baffle is further provided at the upper end of the mounting tube, and the decorative baffle is placed above the diaphragm of the speaker and forms a gap.

[0012] Furthermore, in the above technical solution, a protective net is further provided at the opening of the lower end of the mounting tube, and the protective net is located below the bracket of the speaker.

[0013] Furthermore, in the above technical solution, a decorative ring is further provided on the outside of the installation tube.

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] See Figure 1-5 As shown, a lyric speaker box with an inverted speaker is provided, which includes a box body 100, a display screen 200, a main control board 300, and a speaker 400. The display screen 200 and the main control board 300 are both installed in the box body 100, and the speaker 400 and the display screen 200 are both electrically connected to the main control board 300, and the main control board 300 controls the operation of the speaker 400 and the display screen 200.

[0029] The box body 100 includes a main box 1 and a transparent plate 2 installed at the front end of the main box 1. The transparent plate 2 is located in front of the display screen 200. When the user sees the lyrics and other information displayed on the display screen 200 through the transparent plate 2, the effect of the lyrics and other information being suspended can be achieved, which has a better display effect and is more interesting. It is also convenient for adding some interaction and fun to occasions such as gatherings or KTV.

[0030] The transparent plate 2 can be made of any one of glass, polycarbonate (PC), polymethyl methacrylate (PMMA / acrylic), and polyvinyl chloride (PVC).

[0031] In this embodiment, the speaker 400 is installed inverted on the lower end surface of the box 100, wherein the diaphragm 401 of the speaker 400 is distributed laterally, the diaphragm 401 of the speaker 400 faces the inside of the box 100, and the bracket 402 of the speaker 400 faces downward and connected to the outside of the box 100; the thickness of the speaker 400 is less than the distance between the display screen 200 and the lower end surface of the box 100. That is to say, the present invention no longer directly installs the speaker 400 vertically on the front end of the transparent plate 2, but installs the speaker 400 upside down on the lower end surface of the box. Since the thickness of the speaker 400 itself is much smaller than the diameter, after the speaker 400 is inverted and installed horizontally on the lower end surface of the box 100, the area of the display screen 200 covered by the speaker 400 can be reduced, and the display screen 200 can even be completely not blocked, so that the present invention can better and more completely display lyrics and other information; at the same time, since the speaker 400 is cleverly set up, it does not need to move the display screen 200 upward, so as to ensure that the volume of the entire lyrics speaker will not increase, and it is more convenient to use. In addition, since the speaker 400 is installed inverted on the lower end surface of the box 100, the diaphragm 401 of the speaker 400 faces the inside of the box 100, and the bracket 402 of the speaker 400 faces downward and is connected to the outside of the box 100; the heat generated by the speaker 400 when working is directly dissipated to the outside of the box, and will not bring the heat into the inside of the box 100, that is, it will not affect the temperature resistance and display function of the display screen inside the box 100, thereby achieving the purpose of protecting the display screen.

[0032] A plurality of raising blocks 103 are provided at the lower end of the box body 100 ; when the box body 100 of the present invention is placed on a desktop, the raising blocks 103 come into contact with the desktop, so that a gap is formed between the lower end of the box body 100 and the desktop.

[0033] The box 100 includes at least the following two structures:

[0034] The first structure is as follows: the front end of the main box 1 has a first mounting opening 11, the transparent plate 2 is flat and fixed to the front end of the main box 1 and covers the first mounting opening 11, and the speaker 400 is installed in the first mounting hole on the lower end surface of the main box 1. The first structure is a conventional box body 100 structure.

[0035] The second structure is as follows: the front end of the main box 1 has a first mounting opening 11, and the lower end of the main box 1 has a second mounting opening 12 connected to the first mounting opening 11; the transparent plate 2 is L-shaped, with a first plate 21 at the upper portion of the transparent plate 2 fixed to the front end of the main box 1 and covering the first mounting opening 11. The first plate 21 is positioned in front of the display screen 200, and a second plate 22 at the lower portion of the transparent plate 2 is fixed to the front end of the main box 1 and covers the second mounting opening 12. The speaker 400 is mounted in the second mounting hole 221 of the second plate 22. The second structure is a special box 100 structure that uses an L-shaped transparent plate 2. It is more aesthetically pleasing and more interesting, while also offering better internal transparency and a more ideal decorative effect.

[0036] In this embodiment, which is a preferred embodiment, the box body 100 adopts the second structure mentioned above.

[0037] The angle formed between the first plate 21 and the second plate 22 is 45°-135°. As a preferred embodiment of this embodiment, the adopted scheme is that the angle formed between the first plate 21 and the second plate 22 is 80°-100°, which is in a vertical state or a nearly vertical state.

[0038] The inner walls of the first mounting opening 11 and the second mounting opening 12 are both provided with inlay grooves. The first plate body 21 and the second plate body 22 are both covered with sealing strips on the outside and then inlaid in the inlay grooves and locked by screws. The assembly structure is stable and the sealing performance is excellent.

[0039] In addition, to improve the sound effect, a first passive radiator 101 and a second passive radiator 102 are symmetrically arranged on both sides of the cabinet 100. During operation, the propagation direction of the first sound wave is: after the diaphragm 401 of the speaker 400 vibrates upward, the sound wave formed is directed toward the inner cavity of the cabinet 100, and drives the first passive radiator 101 and the second passive radiator 102 to vibrate, and is radiated by the first passive radiator 101 and the second passive radiator 102 to achieve the first sound. The propagation direction of the second sound wave is: after the diaphragm 401 of the speaker 400 vibrates downward, the sound wave formed is directed downward and connected to the outside of the cabinet 100, achieving the second sound.

[0040] The specific installation structure of the speaker 400 is as follows:

[0041] The speaker 400 is mounted upside down within the mounting tube 5. The lower end of the mounting tube 5 is fixed to the second mounting hole 221 to form a sealed assembly, while the inner cavity of the mounting tube 5 is connected to the outside world to facilitate sound generation and heat dissipation. The outer edge of the diaphragm 401 of the speaker 400 is fixed to the upper opening of the mounting tube 5 to form a sealed assembly, and the mounting tube 5 is located behind the first plate 21. The speaker 400 is fixed to the second mounting hole 221 of the second plate 22 via the mounting tube 5, making its installation more convenient and enabling the diaphragm 401 of the speaker 400 to be installed facing upward. In addition, the mounting tube 5 surrounds the exterior of the speaker 400, which can enhance its aesthetics and decorative properties.

[0042] In order to prevent users from directly seeing the diaphragm 401 of the speaker 400 through the transparent plate 2, thereby improving the decorative effect, the following design is also made: a decorative baffle 51 is also provided at the upper end of the mounting tube 5, and the decorative baffle 51 is placed above the diaphragm 401 of the speaker 400 and forms a gap, which facilitates the diaphragm 401 of the speaker 400 to vibrate and make sounds. The decorative baffle 51 can also block the diaphragm 401 of the speaker 400, thereby improving the decorative effect.

[0043] The lower end of the decorative baffle 51 is provided with a plurality of screw hole columns, and the upper end of the mounting tube 5 protrudes outward to form an outer edge. Screws pass through the outer edge and are screwed into the screw holes of the screw hole columns to fix the decorative baffle 51 to the upper end of the mounting tube 5.

[0044] A protective net 52 is provided at the lower opening of the mounting tube 5 , and is located below the bracket 402 of the speaker 400 to prevent foreign matter from entering and provide protection. The protective net 52 also covers the second mounting hole 221 of the second plate 22 .

[0045] A decorative ring 53 is further provided on the outside of the installation tube 5 to further enhance the decorative effect.

[0046] Recombination Figure 6-9 , which is another structure of the invention, the front end of the decorative ring 53 is also fixedly connected to a tube cover 6, which is also embedded and installed at the lower end of the first plate 21 to form a sealed assembly, and a small speaker 7 is provided inside the tube cover 6. The small speaker 7 is electrically connected to the main control board 300, and the upper edge height of the tube cover 6 is equal to or lower than the lower edge height of the display screen 200, so that the display screen 200 is not blocked as much as possible, so that the display screen 200 can achieve a better display function. The small speaker 7 uses a full-screen speaker, so that the lyrics speaker of the present invention can achieve better pronunciation and improve the sound quality of the lyrics speaker of the present invention.

[0047] Since the barrel cover 6 is also fixedly connected to the front end of the decorative ring 53, the assembly structure is extremely stable.

[0048] A mesh cover 71 is provided at the front end of the barrel cover 6. The mesh cover 71 is located in front of the small speaker 7 to protect the small speaker 7.

[0049] To sum up, the present invention no longer directly installs the speaker 400 vertically on the front end of the transparent plate 2, but installs the speaker 400 upside down on the lower end surface of the box. Since the thickness of the speaker 400 itself is much smaller than the diameter, after the speaker 400 is inverted and installed horizontally on the lower end surface of the box 100, the area of the display screen 200 covered by the speaker 400 can be reduced, and the display screen 200 can even be completely not blocked, so that the present invention can better and more completely display lyrics and other information; at the same time, since the speaker 400 is cleverly set up, it does not need to move the display screen 200 upward, so as to ensure that the volume of the entire lyrics speaker will not increase, and it is more convenient to use. In addition, since the speaker 400 is installed inverted on the lower end surface of the box 100, the diaphragm 401 of the speaker 400 faces the inside of the box 100, and the bracket 402 of the speaker 400 faces downward and is connected to the outside of the box 100; the heat generated by the speaker 400 when working is directly dissipated to the outside of the box, and will not bring the heat into the inside of the box 100, that is, it will not affect the temperature resistance and display function of the display screen inside the box 100, thereby achieving the purpose of protecting the display screen.

[0050] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
