First Claim
Patent Images
1. A method for operating an electronic device including a first microphone and a second microphone, comprising:
- determining by a processor of the electronic device whether a sensor located within a predetermined range from the second microphone has sensed a peripheral object;
blocking by the processor an operation of the second microphone when the sensor has sensed a peripheral object; and
blocking by the processor echo generation by eliminating a sound that is output from a speaker and input to the first microphone.

Abstract
A method for operating an electronic device including a first microphone and a second microphone to block the echo generation the electronic device is operated in a loudspeaker mode. The method includes: determining whether a sensor located within a predetermined range from the second microphone has sensed a peripheral object; blocking an operation of the second microphone when the sensor has sensed a peripheral object; and blocking echo generation by eliminating a sound that is output from a speaker and input to the first microphone.

15. An electronic device including a first microphone and a second microphone, comprising:
-
a sensor located within a predetermined range from the second microphone to sense a peripheral object; and a processor unit for controlling a blocking of echo generation by eliminating a sound that is output from a speaker and input to the first microphone and disabling operation of the second microphone in response to the sensor having sensed the peripheral object. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
