Abstract
A linear vibrator that transmits tactile signals to a user of a mobile phone, PDA, or a portable game console. The linear vibrator uses rubber or silicone rubber having lower elasticity as a material of an elastic body secured to a casing or a base for supporting an oscillator horizontally moving by an electromagnetic force relative to a facing stator, thereby lowering the frequency sensitivity due to a characteristic frequency; reducing various errors of parts and errors in part assembly, thus resulting in smaller deviations of characteristic frequencies between products from mass production; and significantly reducing production cost by using an elastic body made of rubber or silicon rubber instead of steel plate or wire, thereby efficiently producing a structure through a simple assembly process and reducing the manufacture facility cost and labor cost resulting in improved productivity.
