A MOBILE TERMINAL HAVING A FUNCTION OF OUTPUTTING EFFECT SOUND/BACKGROUND SOUND BY USING A KEY BUTTON ON COMMUNICATION

摘要

The present invention relates to a mobile terminal capable of outputting an effective/background sound by using key buttons during a call in order for the on-call effective/background sound selected by the user by using a predetermined key button on a dial pad to be output to a caller's mobile terminal. According to the present invention, in the mobile terminal for modulating voice signals input from a microphone in a wireless communication unit according to a communication method which has been previously established to transmit them through an antenna and demodulating wireless signals received through the antenna in the wireless communication unit to output them through a speaker, the mobile terminal is capable of outputting an effective/background sound by using key buttons during a call by comprising a main module including: a storage unit for storing information of a plurality of key buttons and the effective/background sounds corresponding to the key buttons; a key tone output unit for outputting the effective/background sound corresponding to the key button when the key button is pressed; a transmit signal processing unit for receiving the effective/background sound output in key tones through a speaker means in the microphone and performing a signal processing to output them to the wireless communication unit; and a main controller for controlling the entire system in such a way that, in response to a key button selection signal input from the external, the corresponding effective/background sound can be read from the storage unit and then output to the key tone output unit while the effective/background sound output through the transmit signal processing unit can be transmitted via a predetermined channel.
