Variable mounting sound wave touch pad
A variable mounting sound wave touch pad includes an upper touch pad connected to a microphone to recognize a sound wave. A lower touch pad is spaced apart from the upper touch pad. A plurality of mounting members have one end attached to the lower touch pad and the other end protruding toward the upper touch pad and vary by an actuator which interlocks with the lower touch pad.
1. A variable mounting sound wave touch pad, comprising:
an upper touch pad connected to a microphone to recognize a sound wave;
a lower touch pad spaced apart from the upper touch pad; and
a plurality of mounting members having one end attached to the lower touch pad and another end protruding toward the upper touch pad, heights of the mounting members varying by an actuator which interlocks with the lower touch pad.
2. The variable mounting sound wave touch pad according to claim 1 , wherein the upper touch pad is connected to one microphone.
3. The variable mounting sound wave touch pad according to claim 1 , wherein the actuator deforms the mounting members and interlocks with a system controller which classifies and processes a sound wave signal.
4. The variable mounting sound wave touch pad according to claim 3 , wherein the system controller performs a control to change vibration characteristics of the upper touch pad depending on positions at which the mounting members are grounded to the upper touch pad or the number of grounded mounting members.
5. The variable mounting sound wave touch pad according to claim 1 , wherein the mounting members are provided with an electroactive polymer, and a shape of the electroactive polymer deforms when an electrical signal is applied.
6. The variable mounting sound wave touch pad according to claim 1 , wherein the mounting members are provided with a solenoid plunger which moves when an electrical signal is applied.
7. The variable mounting sound wave touch pad according to claim 1 , wherein the mounting members are provided with a piezoelectric ceramic element, and a shape of the piezoelectric ceramic element deforms by a pressure generated thereon when an electrical signal is applied.
8. The variable mounting sound wave touch pad according to claim 1 , wherein the plurality of mounting members attached to the lower touch pad have different heights in which the mounting members and the upper touch pad are either grounded to each other or are not grounded to each other.
9. A variable mounting sound wave touch pad, comprising:
an upper touch pad connected to a microphone to recognize a sound wave and, the upper touch pad flexibly formed;
a lower touch pad spaced apart from the upper touch pad; and
a plurality of mounting members having one end attached to the lower touch pad and another end protruding toward the upper touch pad, heights of each mounting member being different.
