Abstract
A processing method and a processing system of an audio multichannel output speaker and a mobile phone are disclosed. The method includes: retrieving an audio and video file and establishing four channel signals for audio signals in the audio and video file with independent channel indications; performing frequency-division processing on the four channel signals respectively, and storing data of the four channel signals after frequency-division processing in order; performing digital-to-analog conversion on the data of the four channel signals respectively, and respectively sending converted analog signal data to speakers corresponding to the four channel signals one-to-one.
Claims14
A mobile phone with a processing system of an audio multichannel output speaker, comprising a processor and a memory, wherein the memory is configured to store computer instructions, the processor executes the computer instructions and is configured to:
- retrieve an audio and video file, and respectively establish four channel signals for audio signals in the audio and video file with independent channel indications;
- perform a frequency-division processing on the four channel signals respectively, and store data of the four channel signals after frequency-division processing in order;
- and
- perform a digital-to-analog conversion on the data of the four channel signals respectively, and respectively send converted analog signal data to speakers corresponding to the four channel signals one-to-one;
- wherein the processor is further configured to separate the audio signals in the audio and video file by audio codec algorithm via AAC standard or PCM standard with the independent channel indications, and create audio tracks of four audio channels;
- the audio channels comprising a left front channel, a right front channel, a left rear channel, and a right rear channel;
- and
- wherein the processor is further configured to respectively allocate the four channel signals to different codecs for performing digital-to-analog conversion in clock sequence, and respectively send the converted analog signal data to the speakers corresponding to the four channel signals one-to-one.
