<P>PROBLEM TO BE SOLVED: To provide a method and a device for producing electronic sounds and a mobile apparatus using the same which reduce a noise level of a sampling period (frequency) without large change of the sampling period to reduce an influence upon other devices. <P>SOLUTION: An operation start signal is formed which is obtained by adjusting a period signal having a fixed period by a random time in each period. Arithmetic processing based on waveform data and sound parameters is started by the operation start signal, and arithmetic processing result data is held when prescribed arithmetic processing is terminated, and the arithmetic processing result data is outputted synchronously with the period signal. <P>COPYRIGHT: (C)2004,JPO |
