Audio system, audio device, and audio signal playback method
Provided is an audio device, including: at least one processor; and at least one memory device that stores a plurality of instructions, which when executed by the at least one processor, cause the at least one processor to: play, with a given length of delay, a first-channel audio signal included in an audio signal; obtain one of operation information about operation of the audio device and setting information about playing of the audio signal; and transmit one of the operation information and the setting information, and at least a second-channel audio signal included in the audio signal, to another audio device.
1. An audio device, comprising:
at least one processor; and
at least one memory device that stores a plurality of instructions, which when executed by the at least one processor, cause the at least one processor to:
play a first-channel audio signal included in an audio signal with a given length of delay by at least temporarily storing the first-channel audio signal in a buffer and then outputting the temporarily stored first-channel audio signal from the buffer to an amplifier, the audio signal having the first-channel audio signal and a second-channel audio signal different from the first-channel audio signal;
obtain one of operation information about operation of the audio device and setting information about playing of the audio signal; and
transmit one of the operation information and the setting information, and at least the second-channel audio signal included in the audio signal, to another audio device to thereby cause the another device to play the second-channel audio signal by at least outputting the second-channel audio signal to an amplifier without temporarily storing the second-channel audio signal in a buffer, such that the first-channel audio signal and the second-channel audio signal are played in a synchronized state.
2. An audio signal playback method, comprising:
playing, by a parent device, a first-channel audio signal included in an audio signal with a given length of delay by at least temporarily storing the first-channel audio signal in a buffer and then outputting the temporarily stored first-channel audio signal from the buffer to an amplifier, the audio signal having the first-channel audio signal and a second-channel audio signal different from the first-channel audio signal;
obtaining, by a child device, at least the second-channel audio signal included in the audio signal from the parent device, and playing the second-channel audio signal by at least outputting the second-channel audio signal to an amplifier without temporarily storing the second-channel audio signal in a buffer, such that the first-channel audio signal and the second-channel audio signal are played in a synchronized state;
obtaining, by an operation unit, one of: operation information about operation of one of the parent device and the child device, and setting information about playing of the audio signal; and
transferring one of the operation information and the setting information to another one of the parent device and the child device.
3. The audio signal playback method according to claim 2 , wherein:
the operation unit is provided to one of the parent device and the child device.
4. The audio signal playback method according to claim 2 , wherein:
the operation unit is provided to a terminal device, which is capable of communication to and from one of the parent device and the child device.
5. The audio signal playback method according to claim 2 , further comprising transferring one of the operation information and the setting information via the parent device to one of the child device and a terminal device.
6. The audio signal playback method according to claim 2 , wherein the operation information includes one of an instruction to play the audio signal and an instruction to stop the playing of the audio signal.
7. The audio signal playback method according to claim 2 , further comprising obtaining, by one of the parent device and the child device, the setting information transferred during a period in which the audio signal is being played, and playing one of the first-channel audio signal and the second-channel audio signal, depending on the setting information.
8. The audio signal playback method according to claim 2 , wherein the setting information includes information about one of a volume and equalization of the audio signal.
9. The audio signal playback method according to claim 2 , further comprising setting one of two audio devices, which are included in an audio system, and have the same configuration, as the parent device and another one of the two audio devices as the child device.
10. An audio system, comprising:
a parent device configured to play a first-channel audio signal included in an audio signal with a given length of delay by at least temporarily storing the first-channel audio signal in a buffer and then outputting the temporarily stored first-channel audio signal from the buffer to an amplifier, the audio signal having the first-channel audio signal and a second-channel audio signal different from the first-channel audio signal;
a child device configured to obtain at least the second-channel audio signal included in the audio signal from the parent device, and play the second-channel audio signal by at least outputting the second-channel audio signal to an amplifier without temporarily storing the second-channel audio signal in a buffer, such that the first-channel audio signal and the second-channel audio signal are played in a synchronized state; and
an operation unit configured to obtain one of: operation information about operation of one of the parent device and the child device, and setting information about playing of the audio signal,
wherein one of the operation information and the setting information is transferred to another one of the parent device and the child device.
