VIBRATION DEVICE, DISPLAY SYSTEM, OPERATION DEVICE FOR MOBILE OBJECT, AND MOBILE OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a vibration device which is capable of reducing the probability that vibration attenuates, while being miniaturized, a display system, an operation device for mobile object, and a mobile object.SOLUTION: A vibration device X1 includes: a diaphragm 1 having a second principal surface 1B; a flexible substrate 3 which is provided on the second principal surface 1B of the diaphragm 1 and has a first portion 3A including a first detection electrode 31a for detecting an operation position and a second portion 3B including detection wiring 33 electrically connected to the first detection electrode 31a; and a first vibrating body 2a which is provided on the second principal surface 1B of the diaphragm 1 and vibrates the diaphragm 1. The second portion 3B is spaced from the second principal surface 1B of the diaphragm 1, and the first vibrating body 2a is located between the second principal surface 1B of the diaphragm 1 and the second portion 3B.
