Claim:
1. An electronic cigarette, comprising: a microprocessor; a vocal cavity mounted in an airflow channel of the electronic cigarette; a battery sleeve; and an acoustic-electric conversion unit electrically connected to the microprocessor; the vocal cavity and the acoustic-electric conversion unit are mounted in the battery sleeve; wherein the vocal cavity includes a main body and an extending body connected to the main body, a diameter of the main body is larger than a diameter of the extending body, and the extending body is hollow; the main body defines an air inlet the extending body defines an acoustic groove and an acoustic hole in a circumferential side wall of the extending body, and a center connection line between a center of the acoustic groove and a center of the acoustic hole is parallel to a central axis of the vocal cavity; wherein the acoustic groove forms a slope, the slope gradually approaches the central axis of the vocal cavity from a first end of the slope to a second end of the slope; wherein the first end is away from the main body, and the second end is close to the main body; wherein the battery sleeve defines least one through hole, external airflow enters the electronic cigarette via the air through hole, and an airflow channel is formed; the airflow in the airflow channel enters the extending body which is hollow via the through hole and the air inlet, when the airflow enters the extending body, the slope is driven to vibrate, the vocal cavity is configured to convert the external airflow into an ultrasonic wave with a specific frequency; wherein the acoustic-electric conversion unit is a piezoelectric ceramic piece mounted in an internal sidewall of the vocal cavity, and is configured to convert the ultrasonic wave into a voltage signal and transmit the voltage signal to the microprocessor and; wherein the microprocessor is configured to generate a control signal according to the voltage signal and start a heating and atomizing process of tobacco juice in the electronic cigarette.
