PURPOSE:To enable everyone to sing a song well even though he/she knows no start nor melody of the song with 'KARAOKE' (orchestration without lyrics), by delivering the partial sound recorded to a sound multiplex recording medium through a speaker and also delivering other sound to a headphone or an earphone. CONSTITUTION:The music can be enjoyed stereophonically with a sound multiplex tape 2 when a headphone jack 10 is not put into a headphone terminal 9. Then the jack 10 is put into the terminal 9 and a changeover switch 15 of a canning circuit 12 is changed in three steps as follows. That is, the ordinary stereophonic mode is enjoyed through the headphone 11 only (1st step), the sound A at one side is delivered through the left and right speakers 7 and 8 with the sound B of the other side delivered through left and right speakers 16 and 17 of the headphone 11 (2nd step), and the sound A is delivered through the speakers 16 and 17 of the headphone 11 with the sound B delivered through the speakers 7 and 8 respectively (3rd step). |
