Abstract: An electronic device may include: a memory, a display, a haptic module comprising haptic circuitry, a sound module comprising audio circuitry, and a processor. The processor may be configured to: detect an event for an output of vibration and sound, delay the output of the vibration, change a sound output mode from a first mode to a second mode for fast output while the output of the vibration is delayed, output the sound using the sound module in the second mode, and output the delayed vibration through the haptic module to be synchronized with the output of the sound. As the sound output mode is changed to the second mode, a sound output path may be opened. The sound output path may be changed from the first path for non-fast output to the second path for fast output.

Abstract: A wearable electronic device is provided. The electronic device includes a processor operatively connected to a wireless communication circuit, a first audio mixer, a second audio mixer, a first audio output interface, a second audio output interface, and a speaker, the processor being configured to detect output of a plurality of audio signals including a first audio signal having a first property, transmit the first audio signal having the first property to the first audio mixer, transmit remaining audio signals to the second audio mixer, transmit the first audio signal to the first audio output interface to output the first audio signal through the speaker, synthesize the remaining audio signals into a second audio signal using the second audio mixer, and transmit the synthesized second audio signal to the second audio output interface to output the second audio signal through the external device.
