Disclosed is a sound unit providing improved sound. According to the present invention, the sound unit comprises: a sound wave generator with at least one vibration generating plate, a moving coil, and a magnet generating a magnetic field; a sound wave transmitter which includes a sound wave guide and a plurality of sound wave transmitting holes formed on the front of the sound wave generator; an echo generating space formed on the backside of the magnet of the sound wave transmitter and forms the echo of the magnetic field of the magnet; and a guide part with the echo generating space inside. The sound unit according to the present invention applies oriented and quantified distortion to a portion of a digital sound wave by being integrally formed with the echo forming space and corrects bit noise and sampling frequency noise so as to provide analog sound. |
