Abstract:
A playing sound generating apparatus which is integrated with an image display apparatus such as a TV set, comprising:a remote controller outputting key signal to command generation of a specific sound; a unit sound data storage for storing pulse generating data with respect to a plurality of unit sounds; a timer that generates an interrupt signal; a control for setting an interrupt generating time of the timer in accordance with the corresponding unit sound pulse signal generating data stored in said unit sound data storage when there is a sound generating requirement and checking an output state of a present sound pulse signal whenever the interrupt signal is outputted from the timer and inverting the outputted sound pulse signal; the timer being effective for counting an oscillating signal of a certain frequency outputted by a frequency divider if the interrupt generating die is set by said control and thereby outputting the interrupt signal to said control whenever said oscillating signal reaches a set count value; and a waveform patterning unit for receiving said sound pulse signal from said control and patterning a waveform thereof.
