ABSTRACT:
A multi-mode vibration generating device for a communication terminal includes a first vibration generator and one or more second vibration generators. The first vibration generator includes a first coil assembly and a first magnet and generating a vibration of a given direction by an interaction between an electric field generated by the first coil assembly and a magnet field generated by the first magnet. The one or more second vibration generators include a second coil assembly and a second magnet and generate a vibration of a given direction by an interaction between an electric field generated by the second coil assembly and an magnet field generated by the second magnet. The second vibration generator generates a vibration of a direction or frequency different from a vibration direction or frequency of the first vibration generator, whereby various mode vibrations are generated.
