Abstract
Embodiments of the invention disclose an acoustic wave touch device and an electronic apparatus, which belong to the field of communication and display. The device comprises an acoustic wave touch module and at least one airflow generating module. The acoustic wave touch module comprises a guard plate having at least one through hole. The airflow generating module is arranged at a position to which each through hole corresponds. The acoustic wave touch module is used for generating an acoustic wave that propagates along the surface of the guard plate or passes through the guard plate, and controlling all or part of the at least one airflow generation module to generate airflow that blows to the user's finger via the through hole of the guard plate when it is detected based on the acoustic wave that a user's finger touches the guard plate.
