<p>The present invention relates to a sound transducer and more particularly, to a sound transducer with a sound pressure control function, capable of controlling the sound pressure of an electric signal (sound signal) applied from the outside according to the setting of a user. The sound transducer with the sound pressure control function according to the present invention includes a frame, a magnetic circuit which is installed in the frame, a voice coil which receives the electric signal and is vibrated by mutual electromagnetic forces with the magnetic circuit, a diaphragm which generates a sound by vibrating with the vibration of the voice coil, a setting unit which obtains the setting of the user, and a sound pressure correcting device which processes the electric signal from the outside according to the setting of the user from the setting unit and applies the processed signal to the voice coil.
