<p>A new type of audio converter can generates a strong magnetic field in a voice coil setting area using a magnetic energy convergence equipment fixed in the base slot, one side of the voice coil is connected to a lead, the lead goes through a leading hole cut on the base, the other side of the voice coil is fixed on the bottom of a vibrant apparatus, and the whole vibrant apparatus is fixed on the up side of the base, after electrified, the voice coil liberates in the magnetic field, the vibration is transferred through the vibrant apparatus so that the appended portion that is closely coherent to the vibrant plate can generate sounds. The present invention resolves the problem of high cost but low efficiency of the prior speaker, furthermore, the sound wave has no directivity, and the response is quick, the frequency band is wide, which causes a high fidelity.</p> |
