Abstract
Disclosures of the present invention describe a portable smart electronic device, which consists of several first reference microphones, a first loudspeaker, a first error microphone, several of second reference microphones, a second loudspeaker, a second error microphone, and a noise controlling module. Both the first error microphone and the second error microphone are set to have a noise detection direction and face to a first region near to a right ear and a second region near to a left ear, respectively. Therefore, the noise detection direction and an audio broadcasting direction of both the first loudspeaker and the second loudspeaker have a same progress direction. By such arrangement, this portable smart electronic device can be operated to adaptively provide an anti-noise audio to the first region and the second region for establishing a quiet zone in both the two regions by attenuating various environment noises.
