Document Type and Number:
WIPO Patent Application WO/2024/019453
Kind Code:
A1
Abstract:
According to an embodiment, provided may be an electronic device comprising a vibration device, at least one processor electrically connected to the vibration device, and a memory for storing instructions, wherein the instructions, when executed by the at least one processor, cause the electronic device to: increase or decrease a vibration frequency of the vibration device for a predetermined period of time; on the basis of a signal output from the vibration device, obtain a resonant frequency of the vibration device; determine a vibration frequency causing the output of the vibration device at a temperature higher than room temperature to be less than the output at room temperature, as a driving frequency of the vibration device; and control the vibration device to be driven at the determined driving frequency. Various other embodiments are possible.
