Abstract: An electronic device includes a memory, a housing, an acoustic module comprising a coil and an acoustic membrane configured to be movable based on a signal applied to the coil, the acoustic module being disposed in an internal space of the housing, an amplifier, and a processor. The memory may store instructions that when executed by the processor cause the processor to apply a first signal to the coil through the amplifier to move the acoustic membrane in a first direction by a first distance and applying a second signal to the coil through the amplifier to move the acoustic membrane in a second direction different from the first direction and/or to move the acoustic membrane by a second distance different from the first distance after applying the first signal to the coil.
