Utility Model Content

[0004] Based on this, in view of the problem that the vibration effect generated by external large speakers in existing sound-permeable screens affects the reliability of LED display screens, it is necessary to provide an LED cinema display screen.

[0005] The utility model provides an LED cinema display screen, including an LED module unit and a function board. One side of the LED module unit is provided with LED lamp beads, and the function board is arranged on the other side of the LED module. Several of the LED modules form the LED cinema display screen; the LED module unit includes a mini speaker, and the mini speaker is arranged between the LED lamp beads.

[0006] In some embodiments, the LED lamp beads are arranged in an array on the LED module unit.

[0007] In some embodiments, the mini speakers are arranged in an array between the LED lamp beads.

[0008] In some embodiments, the function board includes an audio driver board.

[0009] In some embodiments, the audio driver boards are connected by cables.

[0010] Compared with the prior art, the beneficial effect of the utility model is: Different from the prior art, the utility model solves the problems of poor sound-permeable effect of existing LED movie display screens and the vibration generated by large speakers damaging the reliability of LED display screens by arranging mini speakers between the LED lamp beads and arranging an audio driver board on the back of the LED display module.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0017] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Please refer to Figure 1 and Figure 2, an LED cinema display screen 1, comprising an LED module unit and a function board 4. One side of the LED module unit is provided with LED lamp beads 2, and the function board 4 is arranged on the other side of the LED module. A plurality of the LED modules form the LED cinema display screen 1; the LED module unit includes a mini speaker 3, and the mini speaker 3 is arranged between the LED lamp beads 2.

[0019] In some embodiments, the LED lamp beads 2 are arranged in an array on the LED module unit. The mini speakers 3 are arranged in an array between the LED lamp beads 2. The function board 4 includes an audio driver board, and the audio driver boards are connected by cables.

[0020] Specifically, on the front of the LED display unit module, several small audio module arrays are placed at the gap positions between the LED lamps to form an audio module array, and corresponding audio driver boards are placed on the back of the LED display unit module. The audio driver boards can communicate signals through cables. The LED display screen cabinet is composed of several LED display unit modules and a function board with audio decoding function. The function of the function board with audio decoding function is: on the one hand, it is used to decode the video source signal to the LED display unit of the cabinet to display the correct display picture, and on the other hand, it transmits the decoded audio signal to the audio driver board of the LED display screen through a certain way.

[0021] By arranging mini speakers between the LED lamp beads and an audio driver board on the back of the LED display module, the problems of poor sound transmission effect of the existing LED movie display screen and the vibration generated by large speakers damaging the reliability of the LED display screen are solved.

[0022] The technical features of the above embodiments can be combined arbitrarily.
