Bedsore-preventing mattress combined with sound vibration module and air fibers, and operating method therefor

An operating method for a bedsore-preventing mattress combined with a sound vibration module and air fibers comprising the steps of:

• (S1) selecting a sound source through the controller;
• (S2) retrieving melody information of the selected sound source;
• (S3) converting the melody information into a digital sound signal and a low-frequency vibration signal by the amplifier;
• and
• (S4) outputting the converted digital sound signal through the speaker and outputting the converted low-frequency vibration signal through the tactile transducer,
• wherein the bedsore-preventing mattress comprising :
• an air mattress including an upper fabric, a lower fabric arranged below the upper fabric to be spaced apart from the upper fabric at a predetermined interval so as to form an air cushion layer in the mattress, a plurality of air fibers of a fine thread shank type which are vertically connected between the upper fabric and the lower fabric to respond to external pressure, a lateral fabric which seals the periphery between the upper fabric and the lower fabric, an air injection part disposed at one side to inject air and seal the air mattress, sound mounting recesses which are formed at both width-directional sides of one side of the longitudinal direction to be spaced apart from each other and to be recessed from the upper surface, and a sonic vibration mounting recess formed in the middle of the longitudinal direction to be recessed from the upper surface;
• and a sound vibration module mounted on the air mattress and including a speaker, a tactile transducer, a controller, and an amplifier, the sound vibration module being operated to generate low-frequency vibration and to emit sound through vibration change after amplification or sound change after amplification of a sound source.
