(11) Referring to FIG. 3 and FIG. 4 again, and please simultaneously refer to FIG. 5, which illustrates a first block diagram of the portable smart electronic device of the present invention. In the present invention, the plurality of first reference microphones 12 are disposed in the first housing body 11, and the plurality of first reference microphones 12 are respectively exposed out of different sides of the first housing body 11 by one microphone head thereof. For example, FIG. 4 depicts that the first reference microphones 12 are respectively exposed out of the right side, the top side and the rear side of the first housing body 11. On the other hand, the first loudspeaker 13 is disposed in the first housing body 11 and has a first audio broadcasting side that is exposed out of one side of the first housing body 11, wherein the first audio broadcasting side is configured for facing a first ear of a user of the object G. Moreover, the first error microphone 14 is disposed in the first housing body 11, and is exposed out of one side of the first housing body 11 by one microphone head thereof, such that the microphone head of the first error microphone 14 faces the first ear of the user. Briefly speaking, both the microphone head of the first error microphone 14 and the first audio broadcasting side of the first loudspeaker 13 are exposed out of the same side of the first housing body 11, such that a noise detection direction of the first error microphone 14 and an audio broadcasting direction of the first loudspeaker 13 have a same progress direction.

(12) As FIG. 3 and FIG. 4 show, the plurality of second reference microphones 22 are disposed in the second housing body 21, and the plurality of second reference microphones 22 are respectively exposed out of different sides of the second housing body 21 by one microphone head thereof. For instance, FIG. 4 depicts that the second reference microphones 22 are respectively exposed out of the right side, the top side and the rear side of the second housing body 21. As described in detail below, the second loudspeaker 23 is disposed in the second housing body 21 and has a second audio broadcasting side that is exposed out of one side of the second housing body 21, wherein the second audio broadcasting side is configured for facing a second ear of the user. Moreover, the second error microphone 24 is disposed in the second housing body 21, and is exposed out of one side of the second housing body 21 by one microphone head thereof, such that the microphone head of the second error microphone 24 faces the second ear of the user. Briefly speaking, both the microphone head of the second error microphone 24 and the second audio broadcasting side of the second loudspeaker 23 are exposed out of the same side of the second housing body 21, such that a noise detection direction of the second error microphone 24 and an audio broadcasting direction of the second loudspeaker 23 have a same progress direction.

(13) From FIG. 3, FIG. 4 and FIG. 5, engineers skilled in noise attenuation or reduction technology should know that, the noise controlling module 10 can be a digital signal processor (DSP), a microprocessor, an integrated circuit (IC) comprising field programmable gate array (FPGA) or an ARM processor. In addition, FIG. 5 also depicts that the noise controlling module 10 is coupled to the plurality of first reference microphones 12, the first loudspeaker 13, the first error microphone 24, the plurality of second reference microphones 22, the second loudspeaker 23, and the second error microphone 24.

(14) The noise controlling module 10 commonly comprises a plurality of analog-to-digital conversion unit for respectively applying corresponding signal converting processes to a plurality of first reference signals transmitted from the plurality of first reference microphones 12, a first error signal transmitted from the first error microphone 14, a plurality of second reference signals transmitted from the plurality of second reference microphones 22, and a second error signal transmitted from the second error microphone 24. Herein, it is worth further explaining that, U.S. Pat. No. 10,171,907 has disclosed that the foregoing analog-to-digital conversion unit comprises pre-amplifier, antialiasing filter and an analog-to-digital converter. Therefore, after completing the corresponding signal converting processes, a plurality of first digital reference signals, a first digital error signal, a plurality of second digital reference signals, and a second digital error signal are hence produced.

(15) On the other hand, the noise controlling module 10 further comprises at least one digital signal processing unit for applying at least one digital process to the plurality of first digital reference signals, the first digital error signal, the plurality of second digital reference signals, and the second digital error signal, thereby making the noise controlling module 10 generate a first anti-noise signal and a second anti-noise signal based on data that are obtained after completing the at least one digital process. Subsequently, the first anti-noise signal and the second anti-noise signal are transmitted from the noise controlling module 10 to the first loudspeaker 13 and the second loudspeaker 23, respectively. As a result, the first loudspeaker 13 and the second loudspeaker 23 respectively broadcast a first anti-noise audio (sound) and a second anti-noise audio (sound) to a first region near to a right ear and a second region near to a left ear, so as to establish a quiet zone in both the two regions by attenuating various environment noises. Herein, it needs to emphasize that, since how to complete the foregoing digital processes have been taught and disclosed by U.S. Pat. Nos. 10,171,907 and 8,325,934.
