AI Technical Summary

Problems solved by technology

Since the LED screen is spliced ​​by a large number of circuit boards installed with LED chips, the sound cannot penetrate the screen. In this case, if the conventional design of the 22.2 multi-channel audio system is still followed, it is better Not suitable, if the speaker is still placed behind the LED display, the sound effect of the original design channel cannot be guaranteed

Embodiment Construction

[0019] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0020] The present invention is a loudspeaker system suitable for LED display screens, which aims to solve the sound effect problem of using a multi-channel sound system or a similar need to install a loudspeaker behind the screen under the LED display system, and provides three solutions.

[0021] In scheme one of the present invention, if there is a loudspeaker 5 that needs to be installed on the back of the LED display screen 4 in the audio system design, then cancel this loudspeaker 5, and divide the power of the loudspeaker into two according to the original design, as figure 2 and image 3 As shown, two parts, the upper speaker 1 and the lower speaker 2, are set. The upper and lower speakers sound synchronously and in phase, simulating the 5-channel synthetic sound effect of the original speaker3.

[0022] In this sch...

Abstract

The invention discloses a loudspeaker system applicable to an LED display. The invention adopts three schemes: loudspeakers are halved and arranged up and down, and multiple miniature loudspeakers orsmall loudspeakers are arranged on a light-emitting driving circuit board or on the back part of a light-emitting board. The effect of simulating a sound channel originally arranged behind a movie screen in a screen system of an LED cinema is achieved.

Description

technical field [0001] The invention belongs to the field of electronic display, and in particular relates to a loudspeaker system suitable for LED display screens, especially suitable for LED cinemas and LED 3D cinemas and other systems with specific requirements for installation space. Background technique [0002] In general movie theaters, a 5.1-11.1-channel sound system is usually used. This kind of sound system usually does not install speakers behind the screen, which does not affect the sound effect. Speakers behind the screen are recommended. The 22.2 multi-channel sound system is a stereo sound system developed as an "ultra-high-definition" image sound system. It uses speakers configured in three layers of 9 channels on the upper layer, 10 channels on the middle layer, and 3 channels on the lower layer, as well as two-channel low-frequency sound effect speakers. , can reproduce the sound transmitted in the forward, backward, left, right, and up and down directions ...
