Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically to a speaker with 3D subtitles. Background Technology

[0002] A speaker is a device that converts audio signals into sound. In simpler terms, it refers to a speaker enclosure or subwoofer enclosure that has a built-in power amplifier that amplifies the audio signal before the speaker itself reproduces the sound, making it louder.

[0003] Currently, speakers have a simple structure and generally only have a simple LED display screen installed. The images displayed on the LED display screen are flat, resulting in poor display effects. However, naked-eye 3D screen technology is already quite mature, and current speakers lack the installation and use structure for naked-eye 3D screens, leading to a decline in the user experience of the speakers. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a speaker with 3D subtitles, which enhances the audio experience through the 3D screen, thereby solving the problems mentioned in the background art.

Positioning ports are provided on the left and right sides of the end face of the speaker shell. Limiting channels are vertically provided on the inner side of the speaker shell near the positioning ports. Limiting blocks are slidably arranged in the limiting channels. One end of each limiting block is bent to form a limiting part. One side of each limiting part abuts against the top surface of the inner cavity of the speaker shell. Each 3D screen is located on the top of the speaker shell. Elastic components are slidably installed on each 3D screen opposite the positioning ports. Bearings are embedded in each limiting part. A shaft is installed in the inner ring of each bearing. The other end of each shaft passes through the positioning port and is installed on the elastic component.

[0006] As a preferred technical solution, the elastic components all include a first compression spring and a slider. The 3D screen is provided with a groove facing the positioning port. The slider is slidably disposed in the groove. The first compression spring is disposed in the groove. One end of the first compression spring is installed on the inner wall of the groove, and the other end is installed on the slider. The cross-section of the slider and the groove is set in a trapezoidal structure. The other end of the shaft is installed on the slider.

[0007] As a preferred technical solution, the end face of the 3D screen is in frictional contact with the outer wall of the speaker shell, and the opposite faces of the 3D screen are fitted together. The top surface of the inner cavity of the speaker shell is provided with a thickened part, and the top surface of the speaker shell is provided with a groove directly opposite the thickened part. A push plate is provided in the groove, and baffles are vertically installed on both sides of the push plate. The baffles and push plate are combined to form a U-shaped groove. The U-shaped groove is fitted over the outside of the 3D screen, and multiple second compression springs are installed between the push plate and the groove.

[0008] As a preferred technical solution, both sides of the limiting channel are provided with vertical positioning grooves, and both sides of the limiting block protrude to form positioning parts, which are slidably disposed in the positioning grooves.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a speaker with 3D subtitles, including a speaker shell 1 and multiple 3D screens 3. The speaker shell 1 has positioning ports 2 on the left and right sides of its end face. The inner side of the speaker shell 1 near the positioning ports 2 is vertically provided with limiting channels 6. Limiting blocks 7 are slidably arranged in the limiting channels 6. One end of each limiting block 7 is bent to form a limiting part 8. One side of each limiting part 8 is in contact with the top surface of the inner cavity of the speaker shell. The 3D screens 3 are all located on the top of the speaker shell 1. Elastic components are slidably installed on each 3D screen 3 opposite to the positioning ports 2. Bearings are embedded in each limiting part 8. A shaft 13 is installed in the inner ring of each bearing. The other end of each shaft 13 passes through the positioning port 2 and is installed on the elastic component.

[0019] In this embodiment, each elastic component includes a first compression spring 12 and a slider. The 3D screen 3 is provided with a groove facing the positioning port 2. The slider is slidably disposed in the groove. The first compression spring 12 is disposed in the groove. One end of the first compression spring 12 is installed on the inner wall of the groove, and the other end is installed on the slider. The cross-section of the slider and the groove is trapezoidal. The other end of the shaft 13 is installed on the slider.

[0020] In this embodiment, the end face of the 3D screen 3 is in frictional contact with the outer wall of the speaker housing 1, and the opposite faces of the 3D screen 3 are fitted together. A thickened part 9 is provided on the top surface of the inner cavity of the speaker housing 1, and a groove is provided on the top surface of the speaker housing 1 opposite to the thickened part 9. A push plate 11 is provided in the groove, and baffles 5 are vertically installed on both sides of the push plate 11. The baffles 5 and the push plate 11 are combined to form a U-shaped groove. The U-shaped groove is fitted onto the outside of the 3D screen 3, and a plurality of second compression springs 10 are installed between the push plate 11 and the groove.

[0021] In this embodiment, both sides of the limiting channel 6 are provided with vertical positioning grooves, and both sides of the limiting block 7 protrude to form positioning parts. The positioning parts are slidably disposed in the positioning grooves. The limiting block can be positioned by the positioning parts and the positioning grooves, so that the limiting block can only move up and down along the positioning grooves.

[0022] In this embodiment, the length and width of the positioning port 2 match the length and width of the cross-section of the 3D screen 3, so that the 3D screen can be limited by the positioning port when it enters.

[0023] In this embodiment, the 3D screen 3 is an LED naked-eye 3D screen 3. The speaker shell is equipped with a receiver card connected to the 3D screen and a transmitter card. The transmitter card (such as Nova or Lingxingyu) distributes the 3D video signal to the receiver card of the LED screen for control.

[0024] In this embodiment, a handle 4 is installed at one end of the 3D screen 3, which makes it convenient to lift the 3D screen.

[0025] In use, pull the 3D screen upwards along the positioning port with the handle until the 3D screen moves to the outside. At this time, the limiting part can abut against the top surface of the inner cavity of the speaker shell. After rotating the 3D screen around the axis, the friction between the bottom surface of the 3D screen and the speaker shell can position the rotated 3D screen through friction, so that the 3D screen can face various positions. After the 3D screen is rotated to a certain angle, it can be pulled outwards, so that the 3D screen is pulled outwards along the slider. After the 3D screens are set relative to each other, slowly release the 3D screen. The rebound energy of the first compression spring can push the 3D screen inwards, so that the 3D screens come together and stick together, thus forming a large 3D screen, which enhances the display effect. Before the 3D screens are aligned, the baffle can be pressed down to retract into the groove. After the 3D screens are aligned, the baffle is released, and the push plate is pushed upward by the rebound of the second compression spring until the U-shaped groove fits onto the 3D screen, thereby positioning the 3D screens. When not in use, the baffle can be pressed down to retract into the groove, and the 3D screen can be rotated until it is aligned directly with the positioning port. At this point, the 3D screen can be pushed downwards into the speaker housing using the handle. The speaker housing will then protect the 3D screen, greatly reducing the risk of damage. As the 3D screen is inserted, the first compression spring applies a lateral pushing force to it, allowing it to rest against the positioning port, increasing friction between it and the speaker housing and enhancing stability during movement.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
