1122 are located at the two sides of first medium layer 111；Second upper electrode layer 1221 and the second lower electrode layer 1222 are located at
The two sides of second medium layer 121.
According to another example of invention, in the embodiment for including vibration transport layer 130, vibration transport layer 130 is located at
It vibrates between the first electrode 112 of generating layer 110 and the second electrode 122 of vibration receiving layer 120.For example, vibration transport layer 130
The second electrode of the first upper electrode layer 1121 and vibration receiving layer 120 of the first electrode 112 of vibration generating layer 110 can be located at
Between 122 the second lower electrode layer.
According to above structure, touch detecting apparatus 100 is when being not received by touch and when receiving touch operation, vibration
Dynamic state is different.For example, user not in electronic equipment be configured with touch detecting apparatus 100 position carry out touch-control, hold
When the operation such as holding, the vibration generating layer 110 and vibration receiving layer 120 of touch detecting apparatus 100 are in initial vibration state.And work as
