<p>Disclosed are a smoking signal generation method, an apparatus and an electronic cigarette. The method comprises the following steps: when airflow passes through a sound production cavity, the sound production cavity vibrating to generate an ultrasonic wave; an acoustoelectric conversion unit arranged on the sound production cavity converting the ultrasonic wave into a voltage signal; and based on the voltage signal, a microprocessor generating a control signal so as to start a process for heating and atomizing cigarette liquid. A beneficial effect of implementing the present invention is: the sound production cavity is independent from other components, and infiltration of the cigarette liquid will not make a smoking signal generation apparatus lose effectiveness; when a user uses an electronic cigarette, the smoking airflow flows through the smoking signal generation apparatus, improving sensitivity and making generation of a smoking signal more accurate and sensitive; and a service life of the electronic cigarette is prolonged.</p> |
