摘要:
A linear motor and a camera module having the linear motor are provided. The linear motor includes: a piezoelectric substrate generating a vibration mode in a longitudinal direction on the basis of an applied voltage; first and second shafts coupled to both sides of the piezoelectric substrate with the piezoelectric substrate interposed therebetween; and a moving member coupled to at least one of the first and second shafts to be movable in the longitudinal direction of the first and second shafts and connected to a camera lens on one side. Accordingly, it is possible to remove a dead zone with a simple structure, to prevent an unnecessary increase in thickness, not to cause a stoppage at the time of moving a camera lens, to cause a small amount of tilt to enable a linear control, and to contribute to a decrease in thickness and a compactness of a mobile terminal.
