Referring to fig. 1, a conventional microphone generally includes a package structure including a housing 1 with an opening at one end and a base plate 2 with printed contacts, a parallel plate capacitor 3 including a diaphragm and a pole plate is disposed inside the package structure, and an annular support 4 is disposed between the parallel plate capacitor 3 and the base plate 2. A field effect transistor 21 is provided on the bottom plate 2 and coupled to the parallel plate capacitor 3 through the elastic electrode 5. The other side (exposed side) of the base plate 2 is provided with printed contacts including a positive terminal, a negative terminal and a signal output terminal for coupling to a power supply and outputting a signal, respectively. In order to prevent dust from entering, a dust cover 6 is additionally arranged at one end of the shell 1 provided with the opening. When the parallel plate capacitor 3 works, the vibration of the vibrating diaphragm caused by the flow of the air flow can be converted into a capacitance change signal, and the capacitance change signal is further amplified into an electric signal by the field effect transistor to be output, so that the air flow is detected. Such microphones are often used in electronic cigarettes as airflow sensors to achieve a self-priming function. However, the function is relatively single, and a control circuit board needs to be additionally arranged in the electronic cigarette.

The mounting modes of the multifunctional microphone and the airflow channel can be arranged according to actual requirements, and are not specifically described herein.

When the electronic cigarette is used, after the electronic cigarette cartridge 100 is inserted into the host plug-in cavity 201, when a suction port at the top of the electronic cigarette cartridge 100 sucks, airflow flows from the airflow channel of the host core.
