Disclosed is a mattress having a sound-to-vibration conversion apparatus, which internally possesses a sound-to-vibration conversion apparatus, so that the mattress may generate alpha-wave by the apparatus vibration, and promote a good sleep and secretion of growth hormone. The sound-to-vibration conversion apparatus in the present invention comprises two magnets having N-pole and S-pole formed on one plane, the magnets being fixed to face each other in a housing; and an electromagnet, which is arranged to pivot centering around a shaft that is installed side by side with the two magnets in the center of the housing; and an inertial weight included which is symmetrically located with regard to the shaft. |
