Abstract

In an electronic device including a driving circuit, it is determined whether the vibrator of the cartridge is connected to the driving circuit of the electronic device, and when the vibrator is connected to the driving circuit, an operating frequency of the vibrator is determined by supplying a test signal to the driving circuit, and a target signal having the operating frequency is supplied to the driving circuit.

First claim

1 . A method of controlling a driving circuit of an electronic device, the method comprising:
determining whether a vibrator of a cartridge is connected to the driving circuit; if the vibrator is connected to the driving circuit, determining an operating frequency of the vibrator by supplying a test signal to the driving circuit; and supplying a target signal having the operating frequency to the driving circuit.

2 . The method of claim 1 , wherein the determining of the operating frequency of the vibrator comprises:
supplying a first test signal having a first test frequency to the driving circuit; and determining the operating frequency based on a response of the driving circuit to the first test signal.

3 . The method of claim 2 , wherein the determining of the operating frequency based on the response of the driving circuit to the first test signal comprises:
if the response of the driving circuit to the first test signal satisfies a preset driving condition, determining the first test frequency as the operating frequency.

4 . The method of claim 2 , wherein the determining of the operating frequency based on the response of the driving circuit to the first test signal comprises:
if the response of the driving circuit to the first test signal does not satisfy a preset driving condition, supplying a second test signal having a second test frequency to the driving circuit; and determining the operating frequency based on a response of the driving circuit to the second test signal.

5 . The method of claim 1 , wherein the determining of the operating frequency comprises:
supplying the test signal having a preset test frequency to the driving circuit; and determining the operating frequency based on a response of the driving circuit to the test signal having the test frequency and pre-stored response data.

6 . The method of claim 1 , wherein when the target signal is supplied to the driving circuit, the vibrator vibrates.

7 . The method of claim 1 , further comprising:
determining whether to continue to drive the vibrator, based on a response of the driving circuit to the target signal.

8 . The method of claim 7 , wherein the determining of whether to continue to drive the vibrator comprises:
if the response of the driving circuit to the target signal is not in a preset threshold range, stopping driving the vibrator.

9 . An electronic device comprising:
a memory; a driving circuit; and a processor configured to:
determine whether a vibrator of a cartridge is connected to the driving circuit;
if the vibrator is connected to the driving circuit, determine an operating frequency of the vibrator by supplying a test signal to the driving circuit; and
supply a target signal having the operating frequency to the driving circuit.

10 . The electronic device of claim 9 , wherein, when the target signal is supplied to the driving circuit, the vibrator vibrates with ultrasonic waves.

11 . The electronic device of claim 10 ,
wherein the electronic device is an aerosol generating device, and wherein an aerosol generating material around the vibrator is aerosolized by vibration with the ultrasonic waves generated by the vibrator.
