▎ 摘  要

NOVELTY - Antistatic sound-absorbing material comprises molecular sieve particles, adhesives and antistatic additives, where the amount of antistatic additive is 0.5-10%, and the antistatic additive includes graphene, carbon nanotubes and/or graphite. USE - The antistatic sound-absorbing material is used as loudspeaker (claimed), and electronic device. ADVANTAGE - The material: has specific surface area of the molecular sieve particles is greater than 300 m2/g, and the pore volume is 0.16-0.32 cm3/g. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing an antistatic sound-absorbing material, comprising mixing raw materials and solvents and molding; and loudspeaker, comprising at least one acoustic sensors, at least one housings, where the acoustic sensors and housings are combined to form the rear chamber of the loudspeaker, and the antistatic sound-absorbing material is installed in the rear cavity of the loudspeaker.
