Abstract

This paper presents a flexible electret loudspeaker using eco-friendly materials like polylactic acid (PLA), paper, and carbon electrodes. The loudspeaker demonstrates strong durability, excellent output (60dB SPL at 50 meters for a 50x40 cm² speaker), and a frequency response consistent up to 15kHz. Its flexible design allows for scalable applications, such as integration with curtains or posters, enhancing human-machine interaction experiences.
