Method and device for processing received sound and memory medium, mobile terminal, robot having the same

A device for processing received sound, comprising:

• at least three microphones, adapted to receive at least three sets of sound;
• a processor adapted to calculate a position of a sounding point in a three-dimensional space according to the at least three sets of sound;
• and
• a position adjusting component adapted to adjust a physical position of the device according to the position of the sounding point in the three-dimensional space and an optimal sound receiving region of the device, so as to approach or contain the position of the sounding point relative to the optimal sound receiving region of the device, wherein the physical position comprises spatial position and orientation of the device.

A non-transitory memory medium, storing instructions for executing the steps comprising

• receiving at least three sets of sound sent by at least three microphones of an apparatus with the non-transitory memory medium;
• calculating a position of a sounding point in a three-dimensional space according to the at least three sets of sound;
• and
• adjusting a physical position of the apparatus with the non-transitory memory medium according to the position of the sounding point in the three-dimensional space and an optimal sound receiving region of the apparatus, so as to approach or contain the position of the sounding point relative to the optimal sound receiving region of the apparatus,
• wherein the physical position comprises a spatial position and orientation of the apparatus.
