Abstract
PURPOSE: To produce imitation sounds readily with a simple constitution without using any tape which has beforehand been recorded with imitation sounds corresponding to information by changing the amplitudes of plural divided outputs respectively according to settings of amplitude setting circuits then combining the same thereby forming the imitation sound signals sorresponding to the information.
CONSTITUTION: The signal of the specified frequency from an oscillator 11 is made to plural different divided outputs by a frequency dividing circuit 12. The amplitudes of these divided outputs are amplitude regulated by the amplitude regulating circuits 13a 13b... of an AGC circuit, etc. to which the control values set by an amplitude control circuit 16 according to an information input unit 17 are applied, after which they are combined in a synthesis circuit 14 to be made to the imitation sound signals corresponding to the information. Hence, the imitation sounds corresponding to the information may be readily generated with a game apparatus with simple constitution without using an tape which has beforehand been recorded according to the information. The similar results may be also be obtained even by controlling the duty ratios, levels, etc. of the divided pulses of frequency dividing circuits constituting a phase locked loop according to information.
