1. An audio device, comprising:
a housing including a first surface, a second surface opposite to the first surface, and a side surface surrounding a space between the first surface and the second surface;
a vibration element disposed on the first surface;
a microphone configured to obtain a sound generated as the vibration element makes an external object vibrate;
a printed circuit board (PCB) disposed in the housing;
a processor disposed on the PCB; and
a communication circuit configured to be electrically connected with the processor and receive a first audio signal from an external electronic device,
wherein the processor is configured to:
generate a second audio signal, such that the vibration element makes the external object vibrate, when the vibration element is attached to the external object;
allow the microphone to obtain a third audio signal generated as the external object vibrates;
generate a transfer function by performing deconvolution of the second audio signal and the third audio signal;
convert a domain corresponding to a specific frequency band in the transfer function and correct the first audio signal based on the converted domain; and
allow the vibration element to make the external object vibrate based on the corrected first audio signal.
