The present invention relates to a sound transducer with a sound pressure controlling function corresponding to a volume, capable of controlling the sound pressure of an electrical signal (a sound signal) which is applied from the outside. The sound transducer with the sound pressure controlling function corresponding to the volume according to the present invention comprises: a frame, a magnetic circuit which is installed in the frame, a voice coil which vibrates by mutual electromagnetic force with the magnetic circuit by receiving the electrical signal, a vibrating plate which generates a sound by vibrating with the vibration of the voice coil, and a sound pressure correcting device which processes the electrical signal applied from the outside based on the gain data which is set by corresponding to the volume and applies the processed signal to the voice coil.
