Definitions
- the shape and/or size of electronic devices are diversifying. In order to enhance mobility, electronic devices with reduced size and/or reduced volume are being designed. Various states can be provided as the posture of the housings of electronic devices is changed. In other words, electronic devices are being designed to be increasingly compact for enhanced portability.
- an electronic device may include a first speaker for outputting a first acoustic signal, a second speaker for outputting a second acoustic signal, and a processor operably coupled to the first speaker and the second speaker.
- the processor may be configured to, when the electronic device is in a first state in which a distance between the first speaker and the second speaker is less than a specified distance, output the first acoustic signal through the first speaker, and output the second acoustic signal through the second speaker so as to have a phase distinct from a phase of the first acoustic signal.
- the processor may be configured to, when the electronic device is in a second state in which a distance between the first speaker and the second speaker is greater than or equal to the specified distance, output the first acoustic signal through the first speaker, and output the second acoustic signal through the second speaker so as to have a phase corresponding to a phase of the first acoustic signal.

- the method may include, when the electronic device is in a second state in which a distance between the first speaker and the second speaker is greater than or equal to the specified distance, outputting the first acoustic signal through the first speaker, and outputting the second acoustic signal through the second speaker so as to have a phase corresponding to a phase of the first acoustic signal.
- phase of the second signal corresponding to the phase of the first signal may mean that the phases of the first signal and the second signal are identical.
- the first speaker and the second speaker are separated by a distance less than the threshold distance, there is an advantage in that sound leakage from the rear of the electronic device can be reduced by outputting a second audio signal having a different phase from the first audio signal.
- the phase of the second signal is different from the phase of the first signal, this may mean that the phases of the first signal and the second signal are opposite.
