Sensing and controlling module of airflow, airflow sensing assembly, and airflow controlling assembly

An airflow sensing assembly comprising:

• an airflow channel including a balancing section and a sensing section;
• a balancing opening communicating with the balancing section of the airflow channel and the environment outside the airflow sensing assembly;
• a communicating opening communicating with the sensing section of the airflow channel;
• a sensing membrane disposed between the balancing section and the sensing section of the airflow channel, the sensing membrane being capable of bending and deforming along an extending direction of the airflow channel;
• the sensing membrane comprising:
• a rim and a surface, the surface surrounded by the rim;
• the rim connected to an inner wall of the airflow channel, and thereby the airflow channel sealed by the sensing membrane;
• a sensing coil adhered to and spread on the surface of the sensing membrane;
• and
• a magnetic unit disposed at a spaced interval from the sensing membrane.

An airflow controlling assembly comprising:

• an airflow channel including an air inlet, the air inlet disposed at one end of the airflow channel;
• a controlling membrane mounted at the air inlet, the controlling membrane being capable of bending and deforming along an extending direction of the airflow channel;
• the controlling membrane comprising a surface;
• a controlling coil adhered to and spread on the surface of the controlling membrane;
• and
• a magnetic unit disposed at a spaced interval from the controlling membrane;
• wherein the controlling membrane further comprises:
• a rim surrounding the surface, and the rim connected to an inner wall of the air inlet, and thereby the air inlet sealed by the controlling membrane;
• and
• at least one perforation hole formed on the controlling membrane, and the at least one perforation hole communicating with the airflow channel.
