REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPS62128062
Kind Code:
A
Abstract:
PURPOSE:To easily find an opportunity to start singing and satisfactorily sign even an unaccustomed song to the accompaniment, by allowing an accompaniment signal to pass a delay circuit to mix it with a microphone output signal and providing a notifying device which detects the start point of a vocal signal before passing the delay circuit and gives a notice. CONSTITUTION:The accompaniment signal and the vocal signal are applied to a circuit consisting of resistors 5-8 and a variable resistor 9, and a moving terminal 9' of the variable resistor 9 is operated to adjust rates of the accompaniment signal and the vocal signal, and they are amplified by a mixing amplifier 10, and the output signal is delayed in a signal delay circuit 18 by 0.5-1sec and passes a variable resistor 11 and is amplified by an output amplifier 16 and is loudened by a speaker 17. Meanwhile, the start part of the vocal signal is detected to operate a one shot multivibrator 23, and a notifying device 24 is operated by the operation of the one shot multivibrator 23. The notifying device 24 gives a visual notice by light emission of an LED, a lamp, or the like or produces synthesized voice 'Hey' or the like as an acoustic signal or taps singer's body with a magnet or the like to give a stimulus.
