cnt-loudspeaker-1A thin film based on carbon nanotubes (CNT) could replace conventional magnetic loudspeakers. By applying an audio frequency current through the CNT, the loudspeaker can generate sound with wide frequency range, high sound pressure levels (SPL), and low total harmonic distortion (THD). The uniqueness of this advancement is that the films are flexible, stretchable, transparent,… »
