Description

Variable Vibration Device of Wireless Terminal

The present invention relates to a wireless terminal, and more particularly to a device that can vary the strength of vibration.

Typically, wireless terminals use vibrations or bells to alert users when a message or call is received. In the case of a bell, a plurality of bells are stored in a conventional manner so that a user of a wireless terminal can rapidly generate various ringing tones. In addition, it is possible to adjust the size of the ringtone in response to changes in the surrounding environment or user needs. On the other hand, in the case of vibration, it is not possible to adjust the magnitude of the vibration with the ringtone, and the vibration is always generated with the same size as the value set at the time of manufacture.

Thus, users who are sensitive to vibration often receive surprises when there is an incoming call, and when the terminal is placed on a hard object such as a desk, a large noise occurs. In addition, if the noise is not sensitive, there is a problem that the phone does not recognize that the vibration is not detected. In the above case, even when the terminal is placed in a thick cloth or in a place such as a bag in the vibration mode, it occurs randomly.

In addition, the use of vibration increases the power consumption significantly more than when using a bell, there is a problem that wastes unnecessary power because the vibration is generated at the same intensity even for users sensitive to vibration.

Accordingly, an object of the present invention is to provide a device that can be generated by varying the intensity of vibration in accordance with the needs of the user.

In order to achieve the above object, the present invention provides a vibration device for a wireless terminal, comprising: a battery for supplying power to the vibration generating device;

A converter having an input stage and a plurality of output stages for receiving power supplied from the battery, and converting the input power into at least two voltages and outputting the DC / DC to the plurality of output stages, respectively, connected to the plurality of output stages. And a plurality of regulators for rectifying the output power and an input terminal are respectively connected to the output terminal of the regulator, and a mux for supplying power to the vibration generator by selecting one of the input terminals by a control signal of the controller. With a variable power supply,

A vibration generating device for generating vibrations by the variable power supplied from the variable power supply device;

And a control unit configured to vary the intensity of vibration by supplying the variable power to the vibration generating device through the variable power supply device in response to a user's request.
