Abstract
An audio signal processing device receives a first voice analog signal from a portable electronic device and a second voice analog signal of noise from outside environment, and converts the first voice analog signal and the second voice analog signal into a first voice digital signal and a second voice digital signal, respectively. The first voice digital signal and the second voice digital signal are then mixed up to obtain a third voice digital signal. The third voice digital signal is converted into a third voice analog signal outputted to an earphone. A regulator is used to adjust signal intensity of the first voice analog signal and the second voice analog signal.
Claims13
An audio signal processing device, comprising:
- a first audio signal input port to receive a first voice analog signal from a portable electronic device;
- a second audio signal input port to receive a second voice analog signal of noise from outside environment;
- an audio decoder-coder for converting the first voice analog signal into a first voice digital signal and converting the second voice analog signal into a second voice digital signal, mixing up the first voice digital signal and the second voice digital signal to obtain a third voice digital signal, and converting the third voice digital signal into a third voice analog signal;
- a regulator for adjusting signal intensity of the first voice analog signal and the second voice analog signal;
- and
- an audio signal output port to output the third voice analog signal to an earphone.
An electronic device capable of playing media files stored therein to provide a first voice analog signal, the electronic device comprising:
- a first audio signal input port for receiving the first voice analog signal;
- a second audio signal input port for receiving a second voice analog signal of noise from outside environment;
- an audio decoder-coder for converting the first voice analog signal into a first voice digital signal and converting the second voice analog signal into a second voice digital signal, mixing up the first voice digital signal and the second voice digital signal to obtain a third voice digital signal, and converting the third voice digital signal into a third voice analog signal;
- a regulator for adjusting signal intensity of the first voice analog signal and the second voice analog signal;
- and
- an audio signal output port to output the third voice analog signal to an earphone.
