Title:

ELECTRONIC DEVICE AND METHOD FOR DETECTING BLOCKED STATE OF MICROPHONE

Document Type and Number:

WIPO Patent Application WO/2020/162694

Kind Code:

A1

Abstract:

An electronic device according to an embodiment may include: a first sound input device configured to obtain external sound and produce a first signal and a processor operatively connected to the first sound input device. The processor may be configured to: receive the first signal from the first sound input device; produce a first high-frequency signal by passing the first signal through a high-pass filter to; determine a first energy value of the first high-frequency signal; determine a second energy value of the first signal; compare a product of the second energy value of the first signal and the first energy value of the first high-frequency signal with a first threshold value to produce a first result; and determine whether the first sound input device is blocked based on the first result. In addition, various other embodiments may be provided.
