The present invention relates to a vibration generating device for a personal communication terminal, and more particularly, to a vibration generating device mounted on a personal communication terminal such as a mobile phone, a PDA and a notebook to vibrate according to an input signal to inform the operation state.

In general, portable communication terminals such as mobile phones (cellular phones and PCS phones), PDAs, and notebook computers are equipped with an electronic acoustic transducer to enable sound output.

The electro-acoustic transducer includes a speaker receiver buzzer capable of outputting voice and sound, and is largely classified into a vibration generator that generates vibration force and outputs vibration sound.

The present invention is constructed such that the vibrator including the magnet and the top plate can be vertically flowable to the main body, thereby vibrating vertically according to the current input to the coil fixed to one side of the main body. Therefore, the current can be input to the coil without a separate brush, and the vibration force is vertically improved, so that the vibration force is improved compared to the rotary type.

Specifically, the structural features of the present invention will be described. In the coin-type vibration generating device, an electromagnetic force is generated in accordance with a case having a housing shape protecting a magnetic circuit to be accommodated and a signal input in the aforementioned case. A main body including a cover coupled to an opening of the case so that the coil is provided, the cover to seal the case to the outside, and a vibration shaft penetrating the case and the cover to form a vibration path; A magnet and a top plate for generating a magnetic force to react in response to the above-described coil are provided on one side, and are provided with a ballistic body that is inserted into the center of both sides to support the yoke and is elastic. Penetrated in, characterized in that it comprises a vibrator vibrating while flowing by the magnetic force of the magnet and the electromagnetic force of the coil.
