At the moment, the sound of the external microphone can be heard by the external earphone or the sound box.
In the JSX3788 state of the access chip, if a monitor switch is double-clicked, the sound effect of a microphone can be set. Similarly, the coding input channel of the chip JSX3788 inputs two groups of externally-hung microphone signals (one of two) into the processor, the signals enter the internal DSP after being coded in the chip JSX3788, various sound effects and sound variation processing can be added in the DSP, and after the coding is finished, the MCU can directly couple the microphone digital coding signals to the audio output signals for simultaneous decoding, thereby outputting the signals to the ear playing end. At the moment, the external earphone or the sound box can hear the sound with sound effect or sound variation of the external microphone.
In the state of the access chip JSX3788, if the external terminal equipment is in a conversation state or has a microphone input request, one path of microphone signals are selected according to the working principle to be directly coded and enter the external terminal equipment such as a mobile phone or a PC/Pad and the like.
