Sound absorption fabric capable of enabling materials to be contacted and electrified based on yarn vibration and preparation method and application of sound absorption fabric

The invention discloses a sound-absorbing fabric enabling materials to be contacted and electrified based on yarn vibration and a preparation method and application of the sound-absorbing fabric, and belongs to the field of sound-absorbing materials. The sound-absorbing fabric provided by the invention comprises a raising fabric layer and a perforated layer, the electrostatic sequences of vibrating yarns in the raising fabric layer are different from those of perforated materials in the perforated layer, the vibrating yarns are inserted into holes of the perforated materials, the vibrating yarns and the perforated materials are in contact and separated, charge transfer is generated, and sound energy is converted into electric energy; meanwhile, sound energy is converted into heat energy through the porous structure of the fabric, and the sound absorption effect is achieved. On the basis of the porous sound absorption principle, the fabric has an additional sound energy consumption path through contact electri
