MOBILE TERMINAL HAVING TWO-STEP VIBRATION DESTINATION MODE - THE TERMINAL PROVIDES A USER WITH A SECONDARY VIBRATION SIGNAL STRONGER THAN A PRIMARY VIBRATION SIGNAL GENERATED FROM A VIBRATION MOTOR

摘要

PURPOSE: A mobile terminal having a two-step vibration destination mode is provided to generate a secondary strong vibration signal if a user does not sense a general vibration signal. CONSTITUTION: A secondary vibration signal generator includes a rotating motor(12) fixedly housed inside a case(10) and a plate cam(11) connected to a rotating shaft of the rotating motor(12). A recess portion(13) of the case(10) exposes the plate cam(11) at a certain rotation section and provides an operation space as much as a rotation radius. When the plate cam(11) contacts with a contact portion of the case(10), it converts a rotational motion of the rotating motor(12) to a reciprocating motion of the case(10) including the contact portion.
