AN IMPROVED LOUDSPEAKER

摘要

An improved loud speaker mounting frame having a continuous conic shape in cross section, so that by means of the conic and apertures along the apex on one side of the conic cross section shape the interference of negative sound waves within the cabinet is reduced and resonance problems of the cabinet are eliminated. Efficiency of the loud speaker system is thereby improved. The concept of conic formation includes an improved V-shaped filtering wave modulation plate utilized in small speaker cabinets.
