| description | PROBLEM TO BE SOLVED: To provide a vibration cone and a speaker unit using this which can be reduced in size while strength and an acoustic characteristic are maintained. SOLUTION: The speaker unit is configured by arranging a vibration cone 2, and a drive mechanism 10 which vibrates the vibration cone 2 in a flat frame 11. The vibration cone 2 is composed of a central vibration core strip 20 and a periphery vibration cone strip 30. The outer periphery 22 of the central vibration cone strip 20 and the inside periphery 32 of the periphery vibration cone strip 30 are flexed facing each other and in the amplitude direction. The vibration cone 2 is configured by mutually joining the outer periphery 22 of the central vibration cone strip 20 and the inside periphery 32 of the outer periphery vibration cone strip 30 between both opposite sides. A coil 16 is jointed to the opposite side of the external periphery 22 of the central vibration cone strip 20 of the internal periphery 32 of the external periphery vibration cone strip 30 at the opposite side. Moreover, the external periphery side of the external periphery 33 of the external periphery vibration cone strip 30 flexed in the magnitude direction covers all the peripheries, and is fixed to the internal surface of the frame 11, and the fixed end of the vibration cone 2 is formed.
