PIEZOELECTRIC VIBRATION ELEMENT AND VIBRATION ELEMENT PACKAGE HAVING THE SAME |
摘要 |
A piezoelectric vibration element and a vibration element package having the same are disclosed. The piezoelectric vibration element and the vibration element package having the same in accordance with the present invention includes: a vibrating piece having a first mesa portion and a second mesa portion, which are vibrated by electric signals, formed on one surface and the other surface thereof, respectively; a first excitation electrode formed on the first mesa portion and configured to transfer the electric signals to the first mesa portion; a second excitation electrode formed on the second mesa portion and configured to transfer the electric signals to the second mesa portion; a first post formed on the one surface of the vibrating piece in such a way that one end thereof connected with a lateral surface of the first mesa portion has a same height as that of the first mesa portion; a first connection electrode formed on the first post so that the electric signals supplied from outside are received and transferred to the first excitation electrode; and a second connection electrode formed on the vibrating piece so that the electric signals supplied from outside are received and transferred to the second excitation electrode. |
