Document Type and Number:
WIPO Patent Application WO/2014/030861
Kind Code:
A1
Abstract:
The present invention relates to an acoustic conversion device and, more specifically, an acoustic conversion device having a sound adjustment function capable of adjusting a sound pressure of an electrical signal (an acoustic signal) applied from the outside according to user settings. The acoustic conversion device having the sound adjustment function, according to the present invention, comprises: a frame; a magnetic circuit mounted inside the frame; a voice coil which vibrates due to a mutual electromagnetic force with the magnetic circuit by receiving an electrical signal; a vibration plate for generating sound by vibrating according to the vibration of the voice coil; a setup unit for acquiring user settings; and a sound pressure compensation device for processing an electrical signal applied from the outside according to the user settings and applying the processed electrical signal to the voice coil.
