A bimorph piezoelectric vibrator includes a pair of piezoelectric element layers connected to one of positive and negative poles and a middle electrode plate interposed between the piezoelectric element layers and connected to the other pole. The piezoelectric vibrator generates vibration due to up/down bending displacement by fixing both end portions thereof to an inner surface of a casing of a mobile terminal. A voltage-boosting transformer raises a power source voltage of a mobile terminal to a driving voltage. A driving chip receives the raised driving voltage from the voltage-boosting transformer and drives the piezoelectric vibrator. Weights are attached to at least one of both sides of the piezoelectric vibrator to amplify vibration. Insulation members are provided at both end portions of the piezoelectric vibrator to prevent electricity applied to the piezoelectric vibrator from leaking to the casing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Piezoelectric vibration device for mobile terminal","description":"A piezoelectric vibration device for a mobile terminal is disclosed.
