Sound-processing apparatus and sound-processing method

A sound-processing apparatus comprising:

• at least one set of sound transducers, each set of sound transducers comprising:
• d. a first sound transducer for receiving a left channel signal of stereo source signals and outputting a first sound signal according to the left channel signal;
• e. a second sound transducer for receiving a right channel signal of the stereo source signals and outputting a second sound signal according to the right channel signal;
• f. a third sound transducer for receiving the left channel signal and outputting a third sound signal according to the left channel signal;
• and
• g. a fourth sound transducer for receiving the right channel signal and outputting a fourth sound signal according to the right channel signal,
• h. the third sound signal having a phase opposite to that of the first sound signal and difference between an amplitude of the third sound signal and an amplitude of the first sound signal being less than or equal to a first amplitude threshold value, and the fourth sound signal having a phase opposite to that of the first sound signal and difference between an amplitude of the fourth sound signal and an amplitude of the second sound signal being less than or equal to a second amplitude threshold value;
• and
• a sound acquisition device for acquiring a sound signal, first path-characteristic difference between an amplitude-frequency characteristic of a first sound path from the first sound transducer to the sound acquisition device and an amplitude-frequency characteristic of a third sound path from the third sound transducer to the sound acquisition device being less than or equal to a frist characteristic threshold value, and second path-characteristic difference between an amplitude-frequency characteristic of a second sound path from the second sound transducer to the sound acquisition device and an amplitude-frequency characteristic of a fourth sound path from the fourth sound transducer to the sound acquisition device being less than or equal to a second characteristic threshold value.

A sound-processing method comprising:

• receiving an audio source signal by a sound-processing apparatus, the sound-processing device comprising at least one pair of sound transducers and a sound acquisition device, each pair of sound transducers comprising a first sound transducer and a second sound transducer;
• outputting, by the first sound transducer, a first sound signal according to the audio source signal;
• and
• outputting, by the second sound transducer, a second sound signal according to the audio source signal, the second sound signal having a phase opposite to that of the first sound signal, and difference between an amplitude of the second sound signal and an amplitude of the first sound signal being less than or equal to an amplitude threshold value.
