Sound mode control method and laser TV

Abstract

The invention provides a sound mode control method and a laser television. The laser television comprises a Soc and a processor chip. The SoC and the processor chip are connected for cooperative work; the processor chip and a loudspeaker box at the exterior of the laser television are connected through a serial port; after a target sound field mode switching instruction sent by a user is received by the SoC, the processor chip obtains current sound field mode information of the loudspeaker box and sends the information to the SoC; the SoC, when determining that the loudspeaker box is in a laser cinema mode, sends a control instruction to the processor chip, so that the processor chip is connected with the loudspeaker box through the serial port and sends the control instruction to the loudspeaker box, and the sound field mode of the loudspeaker box is further switched to the target mode based on the control instruction; and the target mode is any mode in the laser cinema mode. In the process, the sound field mode of the loudspeaker box can be switched between various modes in the laser cinema mode.

Description

technical field [0001] Embodiments of the present invention relate to television technology, in particular to a sound mode control method and a laser television. Background technique [0002] Laser theater is composed of laser TV with laser projection function and professional speakers. Among them, laser TV adopts short-focus laser projection technology to realize projection, which makes the image brightness better, richer in color and more realistic in picture. In terms of sound effects, Laser TV supports professional-grade 5.1 sound effects and Dolby surround sound fields, and provides users with different sound field modes by cooperating with speakers. [0003] Specifically, the speaker supports multiple sound field modes, such as ARC mode, Bluetooth mode, Source mode, laser theater mode, etc. By adjusting the sound field mode of the speaker, different sound field modes are provided for users. In addition, the laser cinema mode also includes theater mode, presence 1 mod...

AI Technical Summary

Problems solved by technology

When the GPIO port is removed, the SoC cannot establish a serial port connection with the speaker, so that the sound mode control of the speaker can only be switched between ARC mode, Bluetooth mode, Source mode, and laser theater mode, and the laser theater mode cannot be controlled. Further fine-grained control cannot make the speaker provide different sound field modes under the laser theater mode according to user needs, which in turn makes the sound field modes provided by the speaker to users limited.
