Abstract:
A method for canceling an echo and an electronic device thereof are provided. The electronic device includes a housing, a communication module, a first speaker disposed in a first region of the housing, a second speaker disposed in a second region of the housing, a first microphone disposed adjacent to the first region, a second microphone disposed adjacent to the second region, and a processor. The processor is configured to receive a first audio signal from an external electronic device, and output a first given frequency band, and output a second given frequency band, and provide a first signal by applying a filter capable of passing a band corresponding to the second given frequency band, and provide a second signal by applying a filter capable of passing a band corresponding to the first given frequency band, and provide a second audio signal corresponding to the external audio signal, and transmit the second audio signal to the external electronic device.
