As shown in FIG. 9, the process includes the following steps: Step S902, ensuring that one of the left and right sides of the top of the mobile phone is installed. The handset has a MIC on each of the left and right sides of the bottom end; and ensures that the gyroscope and the proximity sensor are installed next to the handset to answer or make a call; Step S904, enabling the gyroscope, CPU, and audio microcontroller to enter the call state; Step S906, the gyroscope detects the current horizontal angle of the mobile phone in real time; Step S908, and reports the data (horizontal angle) to the CPU; Step S910, the CPU parses the data, determines whether the data is correct, and if the determination result is yes, proceeds to step S912. Otherwise, the process returns to step S906; in step S912, the CPU parses the data to determine whether it is currently in the call snatch mode. When judging, it is necessary to compare the value of the CPU database. The database must include the snatch angle in various occasions, for example, the angle of the flat and prone calls. If the grip angle of the mobile phone is not satisfied, the user may be moving. Mobile phones, no snatch phones, or special cases where the phone is placed flat on the table. The default channel (left or right) can be opened at this time. If it is judged to be a left-hand or right-hand snatch mobile phone, issue a command to the audio microcontroller to open the left or right channel. In addition, a control bar can be added in the voice call setting option to indicate whether the default mode is left-hand mode or right-hand mode, and the user can set according to personal habits, but after the call, if the determined snatch mode belongs to the above special case, Turn on the voice channel in the default mode. That is, it is determined by the above logic processing whether it is a state change of the left hand and the right hand, and if the determination result is YES, the entry step is

S914, otherwise returning to step S906; Step S914, the CPU determines whether it is the left hand, if it is determined to be the left hand, proceeds to step S916, otherwise proceeds to step S918; Step S916, sends the left-hand channel to the frequency microcontroller, proceeds to step S920; S918: Send the right-hand channel to the frequency micro-controller, and proceed to step S922; in step S920, the audio micro-controller includes a processor that manages the channel, such as codec and modem. The audio microcontroller accepts the channel command of the CPU, opens the corresponding channel (ie, the handset and microphone on the left side), and returns a success status value; in step S922, the audio microcontroller includes a processor that manages the channel, such as codec and modem. The audio microcontroller accepts the channel command of the CPU, opens the corresponding channel (ie, the handset and microphone on the right side), and returns a success status value; in step S924, the CPU accepts the return value and turns on the proximity sensor; step S926, the proximity sensor detects the human ear and The distance of the phone (for example, the handset). The proximity sensor can set a monitoring point in the earpiece, and also set a monitoring point near the MIC, and dynamically monitor the distance between the human ear and the earpiece and the distance between the human mouth and the MIC; and send the detection result to the CPU; Step S928, the CPU parses the data, and determines whether the data is correct. If the determination result is yes, the process proceeds to step S930, otherwise, the process returns to step S926; in step S930, the CPU determines whether the audio parameter needs to be adjusted, and if the determination result is yes, Go to step S932, otherwise go to step S926; Step S932, the CPU accepts the data and parses the data, first determines whether the distance between the human ear and the earpiece is within a reasonable range, and if too far, increases the gain parameter of the earpiece, if too close Then adjust the gain parameter of the handset to be small, and the distance parameter of the MIC is the same; the CPU needs to store the distance gain parameter values in the distance, and find the corresponding gain according to the distance; in addition, the proximity sensor can determine whether the left and right hands are correct. Finally, the CPU sends the determined audio parameters to the audio microcontroller; in step S934, the audio microcontroller sets the parameters of the handset and the MIC according to the received audio parameters.
