Problems solved by technology

[0004] Now, there are many ideas of using smartphones or other handheld smart devices as universal remote controls, and there are also commercial products launched, but the actual use is very rare
One of the reasons is that the existing technologies and products cannot be completely separated from the hardware platform, and cannot be used for universal remote control anytime, anywhere.

Embodiment 3

[0086] Figure 8 It is a touch screen interface of a mobile phone remote control program designed for a certain city's IPTV. With these buttons, you can control the IPTV set-top box, choose to watch all the TV programs broadcast by IPTV and watch all the programs stored in IPTV on demand, which meets all our daily requirements for watching IPTV. Figure 9 Is the block diagram of the mobile phone remote control program. In the initialization stage, while drawing the touch screen interface, the program should increase the output volume of the mobile phone to around 2 / 3 of the maximum output volume, and then send out a continuous audio signal of several hundred milliseconds to pre-set the infrared remote control signal transmitter. thermal and capacitive charging. After a button on the touch screen is pressed, it is necessary to check and adjust the output volume of the mobile phone to around 2 / 3 of the maximum output volume, and then play the intermittent audio signal accordin...

Abstract

The invention relates to an infrared remote-control signal transmitter. The infrared remote-control signal transmitter comprises a shell (4), an input end (5), a rectifying circuit (1), an integrating circuit (2), a square wave shaping and transmitting circuit (3) and an output end (6). The audio signal-driven infrared remote-control signal transmitter is wide in application range and simple in operation, and can be connected to an audio output interface of a smart phone and other hand-held smart devices for converting a regular audio signal sent by a specially designed program into a standard infrared remote control signal so as to remotely control various household appliances and smart devices according to intention of a user.

Description

technical field [0001] The invention relates to the technical field of infrared remote control, in particular to an infrared remote control signal transmitter driven by audio signals. Background technique [0002] With the development of science and technology, there are more and more household and public appliances controlled by remote control, and various remote controls are also increasing, which brings great inconvenience to daily storage, search and use. If an old model remote control is lost, it has to be controlled "hands-on". [0003] Smart touchscreen phones are popular with users of all ages, thanks to their graphical user interface and a wide variety of applications and functions. People have become accustomed to carrying their smartphones with them and always keeping them close at hand. Therefore, many individuals and enterprises wish to integrate the functions of the remote control into the smart phone, and use the smart phone as a universal remote control. I...
