| 摘要 |
The present invention relates to an apparatus for vibrating a piezoelectric element to generate vibration by applying a drive voltage to piezoelectric vibrators (2, 2a, 2b) having an electrode board (4) of a conductive element and a piezoelectric element layer (6) arranged on the electrode board (6). An insulation member (10) is installed on the piezoelectric element layer (6) to prevent the applied drive voltage from leaking. A leg (8) is extended from the electrode board (4) in a lower part of the piezoelectric vibrators (2, 2a, 2b) to bond the piezoelectric vibrators (2, 2a, 2b) to a casing (16) in a mobile terminal. An assembly process can be simplified by installing the piezoelectric vibrators (2, 2a, 2b) by bonding the leg (8) extended from the electrode board (4) when installing the piezoelectric vibrators (2, 2a, 2b) in the mobile terminal, and the piezoelectric vibrators (2, 2a, 2b) can be installed in all locations in the mobile terminal since the thickness of the piezoelectric vibrators (2, 2a, 2b) is thinner because other methods to install the piezoelectric vibrators (2, 2a, 2b) are not required. |
