Remote controller for television

Abstract

The invention provides a remote controller for a television. A first transmitting module is arranged at the top end of the remote controller, an acquisition module and at least one second transmitting module, wherein the first transmitting module is used for sending a user remote control command to the television by at least one first infrared photodiode; the acquisition module is used for acquiring a sound signal of a user; the second transmitting module is arranged at the bottom end of the remote controller and is used for transmitting the sound signal to the television, so that the television plays the sound signal. The remote controller has the advantages that the function of a microphone is realized, and a better communication angle is formed between the remote controller and the television, so that the communication quality of sound transmission is improved.

Description

technical field [0001] The invention relates to the field of remote controllers, in particular to a remote controller for a television. Background technique [0002] Existing KTV singing system is mainly used in places of entertainment. The principle is to use a large-capacity computer server system to store video files, transmit digital signals through an Ethernet network, and use the room computer touch screen to order songs and video programs. If this system is used as a household, the cost is too high, the volume is relatively large, and the installation is also inconvenient. [0003] The working principle of the TV remote control is: when the user presses a button on the remote control, the corresponding circuit is connected, and the micro-control chip set in the remote control can detect the connection of this circuit and determine which button the user pressed. one keystroke. Then, the micro-control chip will send out a password signal corresponding to the key. Aft...

Problems solved by technology

[0005] In the above process, the remote controller transmits the sound signal to the TV set by multiplexing the existing first transmitting module 1 for remote control function, such as figure 1 As shown, when the singer is singing, he usually tilts the remote controller at a certain angle, so that when the remote controller realizes the microphone function, the first transmitting module 1 and the infrared receiving area 6 of the TV set have a poor communication angle, resulting in communication. The quality is poor, and the singer's voice cannot be played clearly
