The reason why the door closing sound transmission unit 3 and the door opening sound transmission unit 4 cannot be simultaneously operated is that the signals of the sound transmission units in the enhanced region are only used because the noise interference caused by the sound waves of the sound transmission units in the one group in the suppression region is introduced by the superposition calculation of the two groups of sound waves. In the door closing state, the door closing sound transmitting unit 3 is in an enhancement area for monitoring the voice signal, and in the door opening state, the door opening sound transmitting unit 4 is in an enhancement area for monitoring the voice signal.
Further, the door closing sound transmission unit 3 is arranged on the door body 2, the door opening sound transmission unit 4 is arranged on the box body 1, and when the door body 2 is closed, the door closing sound transmission unit 3 is arranged on the door body 2, so that the voice information outside the door body 2 can be monitored conveniently, the door opening sound transmission unit 4 is arranged on the box body 1, the voice information outside the box body 1 can be monitored conveniently after the door body 2 is opened, and the two sound transmission units are divided into work and do not interfere with each other clearly.

When the door body 2 is in an open or closed state, the command operations to be performed on the door body 2 are often different, for example:
when the door body 2 is closed, the user does not necessarily open the door body 2, and the user may not want to waste the cold air inside to leak out, or only want to save effort and not open the door body 2, as long as the refrigerator informs the storage condition of the food materials inside, most of the information is received by the door closing sound transmission unit 3 at this time;
after the door 2 is opened, since the user can directly see all the contents in the refrigerator, the user will not inquire about the information of the food material any more, and therefore, other voice information operations can be performed, for example, a new food material purchased by the user does not know which area to store in the refrigerator, and the voice command at this time may be: the refrigerator, in which storage drawer the bean products are better placed, is returned to the second drawer in the lower left corner.
Therefore, when the door 2 is opened or closed, the voice content is switched and processed by a more targeted program. When the door body 2 is set to be closed, the corresponding processing program is a door closing logic program, and at the moment, the signal sent by the door closing sound transmission unit 3 is judged according to the possible operation content when the door body 2 is in a closed state; when the door body 2 is set to be opened, the corresponding processing program is a door opening logic program, and at the moment, the signal sent by the door opening sound transmission unit 4 is judged according to the possible operation content when the door body 2 is in an opened state. Thus, two sets of logic programs are used for respectively processing the voice information of different voice transmission units, so that the voice information can be identified more accurately.
Further, the door control device further comprises an audio output device 8 and a display device 7 arranged outside the door body 2, and the control unit 5 controls the display device 7 through a door closing logic program and controls the audio output device 8 through a door opening logic program.
