Abstract
Disclosed is a linear vibration generating device including: a stator including a bracket on which a coil is seated, and a case made of a magnetic material which is engaged to the bracket to form an inner space; a vibrator including a permanent magnet for generating a vibration force in cooperation with the coil, and a weight enclosing a circumference of the permanent magnet; a resilient member which is positioned between the vibrator and the stator to resiliently support vertical oscillation of the vibrator; and a plate which is positioned between the resilient member and the vibrator
