Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further below with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.The present invention is described in detail below in conjunction with attached drawing.
A kind of control method that control signal is transmitted using audible of the present invention, includes following steps:
Step 1: smart electronics product sends the audio for having specific sections frequency data by audio interface to controller
Signal；In the present invention, the drive module that control signal is sent to audio interface, the drive are equipped in the smart electronics product
Dynamic model block has matched driver, and the function of each control button has been defined in driver, such as play/temporarily
Stop, receiving/hang-up, one song of up/down, skip forward/back, functions, the drive module such as hands-free can be realized according to different frequency amplitude
Different control functions.In addition, the controller and audio interface are electrically connected in the present embodiment.
Step 2: controller extracts specific sections frequency data from audio signal；The spy in the present embodiment
The audio signal for determining interval frequency data is the audio signal of 20KHZ~40KHZ.It realizes when controller with audio interface and electrically connects
After connecing, the drive module sends the audio signal of 20KHZ~40KHZ to controller incessantly, between the frequency band
Control signal of the audio signal as the controller.
Step 3: the controller sets the control button of multiple and different Frequency and Amplitudes according to specific sections frequency data,
Each control button has independent control function, and the function of having defined in function and driver corresponds.When
It presses the control button in some Frequency and Amplitude and forms feedback signal later, feedback signal is passed through audio interface and sent out by controller
It send to smart electronics product, relevant control function is executed by smart electronics product.Further, in this step 3, work as feedback
Signal is sent to smart electronics product, and the drive module detects frequency and the amplitude of feedback signal to judge the control button
Function, smart electronics product just execute relevant control function.
