Problems solved by technology

[0003] Although the above-mentioned existing universal remote control is convenient, it is still an independent remote control. Users still need to purchase this device for remote control of various home appliances, and it is impossible to simply integrate the functions of this universal remote control, which is common in daily life. Portable wireless terminal devices, such as mobile phones or tablet computers, etc.
In addition, the existing universal remote control cannot further interact with the user through the application program, and its function is very limited to simple frequency switching to control home appliances, and most of the existing universal remote control does not have infrared rays learning function

Embodiment Construction

[0042] Specific embodiments are listed below to describe the content of this case in detail, and drawings are used as auxiliary explanations. The symbols mentioned in the description are referenced drawing symbols.

[0043] see figure 1 , which is a system block diagram of the first embodiment of the present invention. Such as figure 1As shown, the headphone microphone connector 10 is coupled to the rectification and filtering module 12 of the voltage doubler circuit, the waveform amplification module 11 and the microprocessor 13 . Among them, the earphone microphone connector 10 sends a right channel signal S2 to the voltage doubler circuit rectifier filter module 12, and outputs a level signal S2' through the voltage doubler circuit rectifier filter module 12, which is sent to the microprocessor 13. The aforementioned level signal S2 ' as a signal to wake up the microprocessor 13 from the sleep state and enter the working state. In addition, the earphone microphone conne...

Abstract

The present invention discloses an audio signal to infrared conversion device, comprising: a voltage-multiplying circuit rectifier / filter module, a waveform amplifier module, a microprocessor, an IR signal emitter module, and an IR signal receiver module. The voltage-multiplying circuit rectifier / filter module is coupled to a headset plug; the waveform amplifier module is also coupled to the headset plug, wherein the voltage-multiplying circuit rectifier / filter module is coupled to either one of a left channel connection part and a right channel connection part of the headset plug, and the waveform amplifier module is coupled to the other one of them. The microprocessor is coupled to the voltage-multiplying circuit rectifier / filter module and the waveform amplifier module. The IR signal emitter module is coupled to the microprocessor. The IR signal receiver module is coupled to the microprocessor and the IR signal emitter module.

Description

technical field [0001] The invention relates to an infrared signal transmitting and receiving device, in particular to a device for converting a sound source signal into an infrared signal and converting the infrared signal into a sound source signal. Background technique [0002] In recent years, due to the advancement of science and technology, the household appliances around the life have developed into a variety of types and wireless operation. However, the ensuing problem is that each household appliance will have an exclusive remote control, making the The number of remote controllers is too many, which causes troubles such as easy loss. In order to solve the above problems, a universal remote control was proposed earlier. Most of this universal remote control uses a single remote control to correspond to multiple brands of TVs, stereos, VCRs, and the fourth channel selector. etc. [0003] Although the above-mentioned existing universal remote control is convenient, ...
