<P>PROBLEM TO BE SOLVED: To provide an acoustic apparatus which generates a novel sound effect when an event command signal showing that supply of a stereo signal is stopped is imparted. <P>SOLUTION: In a normal time, a control part 1300 makes switches 1405 and 1410 be in an ON state and imparts only a left signal and a right signal of a stereo sound source part 1400 to addition parts 1200 and 1250, respectively, so that only the sound of a stereo signal is emitted. Then when the event command signal is imparted, the control part 1300 makes switches 1420 and 1425 be in the ON state at this time, and adds the sound effect generated by inputting two kinds of signals from a loop delay part 1000 to a sound effect generation part 1100 alternately into the addition parts 1200 and 1250 as well, so that the novel sound effect can be obtained by generating the sound effect even if the stereo sound signal from the stereo sound source part 1400 is stopped. <P>COPYRIGHT: (C)2011,JPO&INPIT |
