An electronic device and sound output method thereof are provided. The electronic device may include: an input unit comprising input circuitry configured to sense an input from outside of the electronic device; a plurality of piezo drivers including a first piezo driver and a second piezo driver; and a processor functionally connected with the input unit. The processor may be configured to detect an input through the input unit, to use a first piezo driver set including the first piezo driver to output sounds when the detected input corresponds to a first input, and to use a second piezo driver set including the second piezo driver to output sounds when the detected input corresponds to a second input.
