ACOUSTIC TRANSDUCER APPARATUS HAVING SOUND PRESSURE ADJUSTMENT FUNCTION

摘要

The present invention relates to an acoustic transducer apparatus, and to an acoustic transducer apparatus having a sound pressure adjustment function, capable of adjusting the sound pressure of an electric signal (acoustic signal) applied from an external source. The acoustic transducer apparatus having a sound pressure adjustment function according to the present invention comprises: a frame; a magnetic circuit installed inside the frame; a voice coil which receives an electric signal and vibrates by the electromagnetic force interacting with the magnetic circuit; a vibration plate which vibrates by the vibration of the voice coil to generate sound; and a sound pressure correction device for processing the electric signal applied from an external source and applying the electric signal to the voice coil.
