摘要： The present invention implements a vibrator of a mobile device using: a cantilever (30) made out of a piezoelectric material which contracts or relaxes corresponding to the electric field created by certain voltage level, generating the source vibration; a spring (35) which amplifies the said cantilever's source vibration to the level of vibration required in a mobile device; and external diaphragms (40) amplifying the source vibration together with the spring (35). The present invention thereby extends the length of time in which the device may be used and improves the efficiency in the battery consumption. According to the present invention, the mobile device also may be reduced in size and in weight.
