    摘要： Disclosed herein is an inertial sensor. The inertial sensor includes a sensing unit and a driving-mass-position initialization module. The sensing unit includes a driving mass, a flexible board unit which displaceably supports the driving mass, and a support which supports the flexible board unit to allow the driving mass to move in a suspended state. The flexible board unit has driving electrodes which move the driving mass, and sensing electrodes which sense the movement of the driving mass. The driving-mass-position initialization module includes a position initialization member which reciprocates to initialize the position of the driving mass, and a coil unit which surrounds the position initialization member. An initialization-member-receiving depression is formed in the driving mass. The shape of the initialization-member-receiving depression corresponds to that of the position initialization member.

    摘要： The present invention provides a horizontal linear vibrator which can increase vibration strength while at the same time guaranteeing a sufficiently long lifetime and satisfactory responsivity. The horizontal linear vibrator includes a casing, a bracket, a vibration unit and springs. The bracket and the casing form the internal space therein. A coil is provided above the bracket such that the center axis thereof is oriented in a horizontal direction. The vibration unit is disposed through the coil and comprises a magnetic field generating unit and a weight. The magnetic field generating unit includes a magnet assembly and a yoke. The magnet assembly has magnets which are provided on opposite sides of a magnetic body core such that the similar magnetic poles of the magnets face each other. The weight is mounted to the magnetic field generating unit. The springs are coupled to the casing or the bracket and elastically support the vibration unit.
