Functional overview and development plan of disposable electronic cigarette microphone

The structure of disposable electronic cigarette is simple, which mainly includes oscillator (OSC), protection control module, airflow switch, charging module, LED display module, AT output module and LODIC control. Its control system mainly manages and coordinates pneumatic switches, atomizers, polymer lithium batteries and indicator lights.

Among them, the microphone, as a key component in disposable electronic cigarettes, adopts airflow sensing switch. It is mainly composed of pole piece, diaphragm, gasket, cavity, shell, PCB assembly and LED.

The chip adopts a dedicated ASIC, which has the characteristics of low cost, low power consumption and high performance, and works in a wide voltage range. It integrates undervoltage protection, short circuit protection, over-temperature protection, constant voltage output control, airflow sensor identification circuit and other characteristics. It can be charged by directly connecting 5V voltage to the external charger.

Features of microphone: integrated structure, few components, microphone with LED display, no need for PCBA again, simple assembly and high efficiency!
