Abstract
An earphone device, a communication device, a communication system and a communication method are described. The communication method comprises: collecting a local audio signal comprising a local ambient sound, and performing audio processing before transmission on the local audio signal to obtain a first audio signal when a local audio is allowed to be played and/or talking is allowed; performing audio processing before playback on the first audio signal to obtain a second audio signal, and playing the second audio signal when the local audio is allowed to be played; transmitting the first audio signal to an external device when the talking is allowed.
Claims16
An earphone device comprising:
- a microphone;
- a speaker;
- a communication circuit;
- an audio processing circuit including a first audio processing circuit for processing an audio signal to be transmitted and a second audio processing circuit for processing an audio signal to be played back, the first audio processing circuit configured for receiving an audio signal collected by the microphone, and outputting a first audio signal to the communication circuit and the second audio processing circuit, the second audio processing circuit configured for receiving the first audio signal, and outputting a second audio signal to the speaker;
- and
- a control circuit configured for detecting whether a local audio is allowed to be played, and detecting whether talking is allowed after a call request from an external device is detected,
- wherein when the local audio is allowed to be played and/or the talking is allowed, the microphone is controlled to collect a local audio signal comprising a local ambient sound, and the first audio processing circuit performs audio processing on the local audio signal to output the first audio signal;
- when the local audio is allowed to be played, the second audio processing circuit is controlled to perform audio processing on the first audio signal to output the second audio signal, and the speaker is controlled to play the second audio signal so as to check a sound effect to be perceived at the external device, and
- when the talking is allowed, the communication circuit is controlled to transmit the first audio signal to the external device,
- wherein, after the call request from the external device is detected, the control circuit is configured for first detecting whether listening is allowed, and then detecting whether the local audio is allowed to be played and whether the talking is allowed, or the control circuit is configured for first detecting whether the local audio is allowed to be played, and then detecting whether listening and talking are allowed, and
- wherein, after the listening is allowed, when the local audio is detected as allowed to be played but whether the talking is allowed is not detected, the communication circuit is controlled to transmit a preset fifth audio signal.
A method for communication in an earphone device, comprising:
- collecting, by a microphone, a local audio signal comprising a local ambient sound, and performing audio processing before transmission on the local audio signal to obtain a first audio signal when a local audio is allowed to be played and/or talking is allowed;
- performing audio processing before playback on the first audio signal to obtain a second audio signal, and playing the second audio signal when the local audio is allowed to be played so as to check a sound effect to be perceived at the external device;
- transmitting the first audio signal to an external device when the talking is allowed,
- wherein the audio processing before transmission comprises one or more of analog-to-digital conversion, digital noise reduction, dual microphone noise reduction, and sound effect processing, and the audio processing before playback comprises one or more of digital-to-analog conversion, power amplification, and volume adjustment,
- wherein after the listening is allowed, when the local audio is detected as allowed to be played but whether the talking is allowed is not detected, a preset fifth audio signal is transmitted to the external device.
