PROBLEM TO BE SOLVED: To provide a speaker that can suppress occurrence of distortion in sound to be reproduced.SOLUTION: A flat diaphragm 9 is configured to have a cylindrical structure 11 in which plural cylindrical bodies 10 are sequentially arranged in a plane direction, and plate bodies 12 arranged at the front and back surface sides of the cylindrical structure 11. A part of adhesive agent 14 through which a flange portion 13 and a plate body 12 at the back surface side of the flat diaphragm 9 are fixed to each other is effused into an acute gap 15 between an end portion at the flat diaphragm 9 of a coupling cone 8 and the plate body 12 at the back surface side of the flat diaphragm 9 at the end portion, thereby forming an inner peripheral fixing portion of the coupling cone 8. A cylindrical wall surface 16 of the cylindrical body 10 in the cylindrical structure 11 constituting the flat diaphragm 9 is disposed at the portion of the flat diaphragm 9 which corresponds to the inner peripheral fixing portion of the coupling cone 8.SELECTED DRAWING: Figure 2 |
