Description

Technical Field

[0001] The utility model relates to the technical field of speakers, in particular to a speaker that realizes non-interference in screen flipping. Background Art

[0002] A speaker refers to a device that can convert an audio signal into sound. A speaker is the terminal of the entire audio system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the audio system and is responsible for converting electrical signals into sound signals for people's ears to directly listen to. Speakers are used in occasions such as square dancing, outdoor advertising promotion, and street busking. However, most of these speakers are used outdoors at night, and the existing speakers lack lighting effects; in addition, the existing speakers only have audio effects and no video effects, so they cannot be used for on-site video learning when used in scenarios such as square dancing.

[0003] For example, in the patent document with the Chinese patent application number 202021420364.2 and the publication date of December 29, 2020, a multifunctional speaker is disclosed, and a rotatable display screen is provided on the speaker.

[0004] However, the display screen in this document is directly hinged in the screen groove. In this way, when the screen is flipped, the end of the screen close to the hinge point is likely to collide with the inner wall of the screen groove, resulting in damage, and it also makes the screen can only rotate with the hinge point as the fulcrum, and the rotated screen cannot be lifted in height. Summary of the Invention

[0005] The utility model provides a speaker that realizes non-interference in screen flipping. The screen is connected to the speaker through a connecting rod, and when the screen is flipped, the screen can avoid the side wall of the installation groove, so that the screen flipping will not be interfered.

[0006] To achieve the above object, the utility model provides a speaker that realizes non-interference in screen flipping, including a speaker main body. An installation groove is provided at the top of the speaker main body, and a support assembly is provided in the installation groove. The support assembly includes a mounting plate, a first support connecting rod, a second support connecting rod, and a connecting plate. The mounting plate is fixed on the installation groove. One end of the first support connecting rod is hinged to one end of the mounting plate, and the other end of the first support connecting rod is hinged to one end of the connecting plate. One end of the second support connecting rod is hinged to the center of the mounting plate, and the other end of the second support connecting rod is hinged to one end of the connecting plate. A screen is provided on the connecting plate, and the screen is received in the installation groove under the swing of the first support connecting rod and the second support connecting rod.

[0007] In the above structure, the screen is connected to the speaker main body through the first support link and the second support link. Thus, when the screen needs to be flipped up, the first support link swings with the hinge point with the mounting plate as the pivot and drives the screen to move upward. At the same time, the second support link swings with the hinge point with the mounting plate as the pivot and drives the other end of the screen to move upward. As a result, the screen can be flipped while moving upward, ensuring that the screen can avoid the inner wall of the mounting groove when flipped and preventing the screen from colliding with the inner wall of the mounting groove during flipping. When the screen needs to be retracted, the first support link swings with the hinge point with the mounting plate as the pivot and drives one end of the screen to move forward. At the same time, the second support link swings with the hinge point with the mounting plate as the pivot and drives the other end of the screen to move downward. When the first support link and the second support link swing to the lowest end, the screen is retracted into the mounting groove.

[0008] Furthermore, a placement groove is provided above the mounting groove. When the first support link and the second support link swing downward, they drive the screen to move downward and retract it into the placement groove.

[0009] With the above arrangement, through the placement groove, the screen can be placed flat on the placement groove, so that the screen is not suspended, facilitating transportation.

[0010] Furthermore, the top end of the mounting plate extends obliquely from one end of the mounting plate to the other end; the bottom end of the connecting plate extends obliquely from one end of the connecting plate to the other end; when the first support link swings downward, one end of the connecting plate approaches the other end of the mounting plate.

[0011] With the above arrangement, through the inclined surface settings of the mounting plate and the connecting plate, when the first support link and the second support link swing to the lowest end, the contact surfaces of the mounting plate and the connecting plate can avoid each other. Thus, it is convenient to retract the screen.

[0012] Furthermore, a speaker is provided at the front end of the speaker main body.

[0013] With the above arrangement, by providing the speaker, it is convenient for the speaker to emit sound.

[0014] Furthermore, rolling wheels are provided at the bottom end of the speaker main body.

[0015] With the above arrangement, it is convenient to move the speaker main body through the rolling wheels.

[0016] Furthermore, handles are provided on both sides of the speaker main body.

[0017] With the above arrangement, it is convenient to carry the speaker main body through the handles.

[0018] Furthermore, the inner side wall of the mounting groove is inclined upward and outward.

[0019] With the above settings, the inner wall of the installation groove is inclined upward and outward, so that the upper opening of the installation groove is larger than the lower opening, so as to better avoid the support component. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] As Figures 1 - 5 shown, a speaker that realizes non-interference in screen flipping includes a speaker main body 1. An installation groove 2 is provided at the top of the speaker main body 1. A support component 3 is provided in the installation groove 2. The support component 3 includes a mounting plate 31, a first support link 32, a second support link 33, and a connection plate 34. The mounting plate 31 is fixed on the installation groove 2. One end of the first support link 32 is hinged to one end of the mounting plate 31, and the other end of the first support link 32 is hinged to one end of the connection plate 34. One end of the second support link 33 is hinged to the center of the mounting plate 31, and the other end of the second support link 33 is hinged to one end of the connection plate 34. A screen 10 is provided on the connection plate 34. The screen 10 is received into the installation groove 2 under the swinging of the first support link 32 and the second support link 33.

[0027] As Figure 3 shown, a placement groove 21 is provided above the installation groove 2. When the first support link 32 and the second support link 33 swing downward, they drive the screen 10 to move downward and be received into the placement groove 21. The inner wall of the installation groove 2 is inclined upward and outward, and the opening of the placement groove 21 is larger than the upper opening of the installation groove 2, so that a stepped portion is formed between the placement groove 21 and the installation groove 2. Through the placement groove 21, the screen 10 can be placed flat on the placement groove 21, so that the screen 10 will not be suspended, which is convenient for transportation.

[0028] As Figure 2As shown, the top end of the mounting plate 31 extends obliquely from one end of the mounting plate 31 to the other end of the mounting plate 31; the bottom end of the connecting plate 34 extends obliquely from one end of the connecting plate 34 to the other end of the connecting plate 34; when the first support link 32 swings downward, one end of the connecting plate 34 approaches the other end of the mounting plate 31. By providing the inclined surfaces of the mounting plate 31 and the connecting plate 34, when the first support link 32 and the second support link 33 swing to the lowermost end, the contact surfaces of the mounting plate 31 and the connecting plate 34 can avoid each other. Thus, it is convenient to store the screen.

[0029] As Figure 1 shown, a speaker 11 is provided at the front end of the speaker main body 1. By providing the speaker 11, it is convenient for the speaker to emit sound.

[0030] Rolling wheels 12 are provided at the bottom end of the speaker main body 1. By means of the rolling wheels 12, it is convenient to move the speaker main body 1.

[0031] Handles 13 are provided on both sides of the speaker main body 1. By means of the handles 13, it is convenient to carry the speaker main body 1.

[0032] The beneficial effects of the present utility model: The screen 10 is connected to the speaker main body 1 through the first support link 32 and the second support link 33. Thus, when the screen 10 is to be flipped up, the first support link 32 swings with the hinge point with the mounting plate 31 as the fulcrum and drives the screen 10 to move upward, and at the same time, the second support link 33 swings with the hinge point with the mounting plate 31 as the fulcrum and drives the other end of the screen 10 to move upward. Thus, the screen 10 can be flipped while moving upward (as Figure 5 shown), so as to ensure that the screen 10 can avoid the inner wall of the installation groove 2 when flipping, and prevent the screen 10 from colliding with the inner wall of the installation groove 2 when flipping; when the screen 10 is to be retracted, the first support link 32 swings with the hinge point with the mounting plate 31 as the fulcrum and drives one end of the screen 10 to move forward, and at the same time, the second support link 33 swings with the hinge point with the mounting plate 31 as the fulcrum and drives the other end of the screen 10 to move downward. When the first support link 32 and the second support link 33 swing to the lowermost end, the screen 10 is retracted into the installation groove 2 (as Figure 4 shown).
