Piezoelectric vibrator and electronic device using same
View Patent ↗A piezoelectric vibrator is used in an electronic device having a screen. The piezoelectric vibrator includes a diaphragm, at least one piezoelectric layer attached to the diaphragm, and a vibrating element extending from the diaphragm for being coupled to a surface of the screen.
1. A piezoelectric vibrator, used in an electronic device having a screen, comprising:
a diaphragm;
at least one piezoelectric layer attached to the diaphragm;
electrodes provided between the diaphragm and the piezoelectric layer for providing electric field to the piezoelectric layer; wherein
the diaphragm comprises a body and a vibrating element extending from the body; and
the vibrating element comprises a first portion extending from the body and second portion perpendicular to the first portion for being coupled with the screen.
2. The piezoelectric vibrator as described in claim 1 , wherein the piezoelectric layer is made of ceramic material.
3. An electronic device comprising:
a screen;
a piezoelectric vibrator coupling to a bottom of the screen and defining a diaphragm, at least one piezoelectric layer attached to the diaphragm;
electrodes provided between the diaphragm and the piezoelectric layer for providing electric field to the piezoelectric layer; wherein
the diaphragm comprises a body and a vibrating element extending from the body; and
the vibrating element comprises a first portion extending from the body and second portion perpendicular to the first portion for being coupled with the screen.
4. The electronic device as described in claim 3 , wherein the piezoelectric layer is made of ceramic material.
