Abstract
A sound-processing apparatus comprises at least one pair of sound transducers. A first sound transducer may receive an audio source signal and output a first sound signal according to the audio source signal. A second sound transducer may receive the audio source signal and output a second sound signal according to the audio source signal, the second sound signal having opposite phase from the first sound signal. A difference between the second and first sound signal amplitudes may be less than or equal to an amplitude threshold value. A sound acquisition device may acquire a sound signal. Path-characteristic differences between amplitude-frequency characteristics of a first sound path from the first sound transducer to the sound acquisition device and a second sound path from the second sound transducer to the sound acquisition device may be less than or equal to a first characteristic threshold value.
