Japanese Patent JP2018093467
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electrostatic type transducer of good handleability while increasing the number of laminations by application of a method for winding like a roll, and a method for manufacturing the same.SOLUTION: An electrostatic type transducer 1 comprises an electrostatic type unit 10. The electrostatic type unit is arranged by winding a first laminate sheet 110 and a second laminate sheet 120 like a roll and shaping the resultant roll in a flat form. The first laminate sheet 110 includes: a first electrode sheet 111; and two first dielectric sheets 112, 113 laminated on opposing faces of the first electrode sheet 111 respectively. The second laminate sheet 120 includes: a second electrode sheet 121; and two second dielectric sheets 122, 123 laminated on opposing faces of the second electrode sheet 121.SELECTED DRAWING: Figure 1
