Abstract: In an audio signal transmitting system having an audio signal transferring device and a loudspeaker to reproduce audio signals, the system includes a vibrato device consisting of a charge transfer device (CTD) connected to the transferring device, a clock pulse oscillator to produce clock pulses and supply the clock pulses to the CTD, and an oscillator to supply low frequency signals. The clock pulse oscillator is controlled in its frequency in response to the low frequency signals, so that delayed and frequency-modulated audio signals are reproduced by the loudspeaker.
