A METHOD AND A DEVICE OF AUTOMATIC CONTROLLING AMPLIFYING LEVEL WITH RECEIVING SIGNAL FOR MOBILE PHONE

摘要

The present invention sound-level signal by an external physical force that is detected by the piezoelectric sensor attached to the mobile terminal By controlling the level, and the piezoelectric sensor unit for outputting a control signal corresponding to detection of the external physical pressure is applied to the mobile terminal; And a baseband unit that the portable terminal and outputting the sound-level conversion signal received from the radio communication party to a baseband signal; And a level control unit for controlling the output level of the sound-level signal by the amplifier to the control signals from the piezoelectric sensor; A speaker for converting the output signals from the sound-level control in the level of the audio signal is included, and is characterized in a structure made of, also, the method comprising the steps of: determining whether an external physical force is detected by the piezoelectric sensor by the mobile terminal controller; If it is determined that an external physical force is detected in the process, and outputting a control signal corresponding to the detected physical force to the level controller; Characterized by comprising a sound-level signal applied to the process for amplifying the output to the corresponding level to the control signals from the piezoelectric sensor in the process, the automatic control, and the surrounding radio environment or the output level of the sound-level signal in harsh place has the effect of facilitating the process of voice grade communication with the other party.
