Description

Technical Field

[0001] The utility model belongs to the technical field of LED display screens, in particular to a flexible LED display screen with a sound-transmitting function. Background Art

[0002] LED display is a perfect combination of technology and media. It can perfectly present the concepts of fantasy, technology, trend, fashion, etc., and brings great vitality and beauty to the city. With the continuous development of China's LED display industry, these displays have spread all over the streets and alleys of major cities, which not only enhances the city's image, but also greatly enriches people's cultural life.

[0003] With the continuous advancement of technology, the functions of LED display screens are becoming more and more diversified. They are widely used in many fields such as commercial advertising, real-time broadcasting, traffic diversion, stage rendering, etc. However, traditional LED display screens do not have the function of sound transmission, which limits their application scope and effect to a certain extent. In order to improve this situation, some LED display screens adopt the solution of placing speaker equipment around or at the back, but this solution has some problems.

[0004] First, because the speakers are placed around or behind the display screen, the stereo surround effect is poor and it is impossible to achieve accurate sound positioning synchronized with the picture. When watching, the audience may feel that the sound and the picture are not coordinated, which affects the viewing experience.

[0005] Secondly, since the size of LED display screens is usually large, the screen has a significant obstructive effect on the speakers behind the screen; this causes the audio processing and surround sound effects of the speakers to deteriorate, and the sound reception effect in front of the screen is also weakened accordingly; for occasions that require high sound quality and surround sound, this solution may not meet the requirements. Utility Model Content

[0006] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0007] In view of the following technical problems in the prior art: First, because the speakers are placed around or behind the display screen, the stereo surround effect is poor, and it is impossible to achieve accurate sound positioning synchronized with the picture. When watching, the audience may feel that the sound and the picture are not coordinated, which affects the viewing effect; secondly, because the size of the LED display screen is usually large, the screen has a significant obstruction effect on the speakers behind the screen; this leads to the deterioration of the audio processing and surround sound effects of the speakers, and the sound reception effect in front of the screen is also weakened accordingly; for occasions that require high sound quality and surround sound effects, this solution may not meet the requirements.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions: a flexible LED display screen with sound-transmitting function, comprising a box body and sound-transmitting slots;

[0011] The thickness of the magnetic sheet is not less than 1.5 mm to ensure the magnetic attraction.

[0012] As an optimal technical solution for a flexible LED display screen with sound-transmitting function, the axis of the LED flexible sound-transmitting module corresponds to the axis of the mounting groove on the box, and the size of the LED flexible sound-transmitting module is larger than the size of the hole on the box to ensure that the LED flexible sound-transmitting module is installed on the box.

[0013] As an optimal technical solution for a flexible LED display screen with sound-transmitting function, the magnets are distributed in a surrounding array on the side of the LED flexible sound-transmitting module facing the box, and the magnets distributed in the surrounding array are located at the periphery of the installation groove of the box.

[0014] As a preferred technical solution for a flexible LED display screen with sound-transmitting function, the opening of the sound-transmitting slot is in the form of a circular, square, trapezoidal, triangular or waist-shaped opening.

[0015] As an optimal technical solution for a flexible LED display with a sound-transmitting function, the opening of the sound-transmitting hole is one of the opening forms of a circular shape, a square shape, a trapezoidal shape, a triangular shape, or a kidney-shaped hole.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Flexibility of the box support structure:

[0020] The boxes are directly interlocked with each other through through bolts to achieve seamless splicing; the height difference is eliminated by the upper, lower, left, and right bridging of a single module to ensure a smooth transition and achieve perfect screen display.

[0021] 2. Thin and light design of the LED flexible sound-transmitting module:

[0022] The thickness of the PCB board of the LED flexible sound-transmitting module is limited to 0.6 mm or less. Such a design significantly reduces the weight and volume of the display while ensuring the stable operation of electrical performance;

[0023] The thin and light PCB board enables the LED display to have a smaller splicing arc when splicing; this design not only makes the display more aesthetically pleasing visually but also increases its ability to adapt to various gorgeous and changeable display design effects; whether it is a curve, a curved surface, or other complex-shaped display designs, this thin and flexible display can easily handle them.

[0024] 3. Optimization of the sound-transmitting hole design:

[0025] In this design, sound-transmitting holes are specially provided at the cross centers of adjacent rows and columns of LED light-emitting diodes; this layout ensures that the area of the sound-transmitting holes can be maximized relative to non-cross center positions;

[0026] The sound-transmitting holes with the maximized area mean that the obstruction to the passing of sound is reduced, thereby allowing the audio signal to propagate more freely, reducing distortion and attenuation, and enabling the audio effect to reach the best state.
