The utility model discloses a novel audio converter. The converter comprises an assembled magnetic energy device which is fixed in the groove of a base is used for generating a strong magnetic field in the placement region of a voice coil. One end of the voice coil is connected with a lead wire which is led out from a leading hole that is arranged on the base. The other end of the voice coil is fixed on the bottom face of a vibrating transmission device which is fixed on the upper part of the base. Vibration generates in the magnetic field after the voice coil is electrified. The vibration is transmitted through the vibration transmission device, thus an attachment which is closely attached to the upper surface of a vibration transmission plate vibrates and produces sound. The novel audio converter of the utility model solves the problems of low efficiency-cost ratio and high production cost of an audio converter which adopts rare earth large magnetostrictive material as a driving element, and the generated sound wave has the advantages of non-directivity, rapid response, wide frequency band and good fidelity.
