Title:
AN ELECTRONIC DEVICE AND METHOD FOR PREVENTING CORROSION OF AN AUDIO JACK
Document Type and Number:
WIPO Patent Application WO/2019/231296
Kind Code:
A1
Abstract:
The disclosure provides a technique to prevent and/or reduce a terminal of an audio jack from being corroded due to residual moisture introduced into the audio jack. According to various embodiments of the disclosure, an electronic device may include an audio jack including a plurality of terminals including a first detection terminal and a second detection terminal; at least one processor functionally connected to the audio jack; and a memory. The memory may store instructions that, when executed by the at least one processor, control the electronic device to: detect an occurrence of an insertion interrupt of an object in the audio jack through the first detection terminal, determine whether the object is a jack plug based on an impedance value measured through the second detection terminal, and stop applying a voltage to the first detection terminal when the object is determined not to be the jack plug.
