Tactile presentation device
A tactile presentation device includes: a substrate that has a lower surface on which a vibration generation element is mounted, and an upper surface opposite to the lower surface; a first adhesive layer that is disposed on the upper surface of the substrate; a first elastic layer that is disposed on the first adhesive layer, and has a lower elastic modulus than an elastic modulus of the substrate; wherein the elastic modulus of the first elastic layer corresponding to a frequency of an ultrasonic band of the vibration generation element is equal to or more than 1 GPa.
1. A tactile presentation device comprising:
a substrate that has a lower surface on which a vibration generation element is mounted, and an upper surface opposite to the lower surface;
a first adhesive layer that is disposed on the upper surface of the substrate;
a first elastic layer that is directly in contact with the first adhesive layer, and has a lower elastic modulus than an elastic modulus of the substrate;
wherein the elastic modulus of the first elastic layer corresponding to a frequency of an ultrasonic band of the vibration generation element is equal to or more than 1 GPa.
2. The tactile presentation device as claimed in claim 1 , wherein
the substrate comprising a material that resists being wound in a roll shape, and the first elastic layer comprising a material capable of being wound in the roll shape.
3. The tactile presentation device as claimed in claim 1 , further comprising:
a decorative layer on the first elastic layer.
4. The tactile presentation device as claimed in claim 1 , wherein
at least one of a water repellent agent, an antibacterial agent and a friction reducing agent is included on the first elastic layer or is included in the first elastic layer.
5. A tactile presentation device comprising:
a substrate having a lower surface on which a vibration generation element is mounted, and an upper surface opposite to the lower surface;
a first adhesive layer on the upper surface of the substrate;
a first elastic layer on the first adhesive layer, and having a lower elastic modulus than an elastic modulus of the substrate;
wherein the elastic modulus of the first elastic layer corresponding to a frequency of an ultrasonic band of the vibration generation element is equal to or more than 1 GPa;
a second elastic layer on the first elastic layer, having a thinner thickness than a thickness of the first elastic layer, and having a lower elastic modulus than an elastic modulus of the first elastic layer.
6. The tactile presentation device as claimed in claim 5 , wherein
the second elastic layer is disposed on the first elastic layer through a second adhesive layer different from the first adhesive layer.
7. The tactile presentation device as claimed in claim 5 , wherein
the second elastic layer is directly included on the first elastic layer.
