Abstract
A linear vibration actuator for which the positional accuracy of coils in the casing can be easily increased. A linear vibration actuator (1) in which a magnet (13) and a weight (15) are fixed. The magnet (13) and the shaft (20) form a magnetic circuit within a casing (2) causing reciprocating motion of the weight (15) and magnet (13), via a coil (24) within a casing (2). The linear actuator (1) includes a shaft (20) provided within the casing (2) and made from a magnetic material. A coil (24) is supported by the shaft (20) includes first and second coil parts (22, 23) arranged parallel to an axial line L and wound in opposing directions. A ring-like magnet (13) surrounds the coil (24) and the shaft (20). A weight is fixed to the magnet. A plate spring (17) biases the magnet (13) and the weight (15) along the shaft (20).
