In an image display device such as a TV set, a playing sound generating method generates a sound without using a separate sound source integrating device and also generates a playing sound using the generated sound. To achieve the method, there is provided a playing sound generating apparatus which includes: a key signal input unit setting various functions and having keys for inputting a scale to be generated; an input interface unit receiving and processing a key signal outputted from the key signal input unit; a unit sound data storing unit storing pulse generating data in order to generate specific unit sounds such as a scale; a control unit reading unit sound data stored in the unit sound data storing unit when a specific unit sound or playing sound generation requiring signal is inputted through the input interface unit and generating a sound signal of a square wave type in accordance with the unit sound data; a frequency divider dividing a referential oscillating signal outputted from an oscillator into a predetermined frequency; a timer outputting an interrupt signal to the control unit by counting an output signal of the oscillator after being set by the control unit with a value of the corresponding unit sound data; and an output interface unit externally outputting the sound signal generated from the control unit.
