Each frameless winding voice coil is a planar coil formed by winding a single enameled wire. Each planar coil is of a racetrack or an annular shape and the enameled wires are arranged by tightly contacting to each other. According to the vibration system, the frameless winding voice coils are directly attached to the diaphragm, and lead wires of the voice coils are tightly arranged, so that a space utilization rate in a magnetic gap is effectively improved, so as to improve a driving force factor BL and an output sensitivity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vibration system of ultra-thin full-range loudspeaker","description":"A vibration system of an ultra-thin full-range loudspeaker includes a diaphragm and frameless winding voice coils directly attached to the diaphragm.
