摘要： An electronic apparatus includes a sound-receiving module and a processor. The electronic apparatus is electronically connected to a first sound device and a second sound device. The first sound device receives a first sound signal having a first channel audio from the electronic apparatus and plays the first channel audio. The second sound device receives a second sound signal having a second channel audio from the electronic apparatus and plays the second channel audio. The sound-receiving module receives an audio to generate an input signal. The processor electrically connected to the sound-receiving module compares the input signal and a predetermined value. When the input signal is less than the predetermined value, the processor adjusts the first and second sound signals for the first sound device receiving the second sound signal and for the second sound device receiving the first sound signal.

摘要： An echo-cancelling device includes an audio input/output (I/O) terminal, an audio-receiving module, an analog-to-digital (A/D) converter, and a processor is provided. The A/D converter is electrically connected to the audio-receiving module. The processor is electrically connected to the A/D converter and the audio I/O terminal. The audio I/O terminal receives an external reference signal from an electronic device. The audio-receiving module receives an input audio and an output audio from the electronic device, and generates an analog input signal having the input audio and the output audio. The A/D converter generates a digital input signal according to the analog input signal. The processor cancels the output audio to generate a second (digital) sound signal according to the digital input signal and the external reference signal. Finally, the processor transmits the second (digital) sound signal to the electronic device via the audio I/O terminal.
