Sound signal processor

Abstract

Abstract PURPOSE:To eliminate the need for a function, etc., to detect the position of the slider of a sliding resistor by once making a variable resistor into the one to obtain a resistance value to be the one edge part of a resistance value variable range, thereafter, supplying a driving control signal to a driving means only for a stored supplying time, and making the variable resistor into a driven condition. CONSTITUTION:When a sound signal circuit system 30 is automatically set at an operating condition at a time set beforehand by a timer operation control means 40, variable resistors 19 and 20, which are arranged in the sound signal circuit system 30 and control volume for the voice output, once obtain the resistance value to be the one edge part of the resistance value variable range. Thereafter, they are driven by a driving means 44, to which the driving control signals are supplied for the supplying time set beforehand by means of a supplying time setting means 41, and the resistance value is changed according to the supplying time of the driving control signals. Thus, the condition of the driving type variable resistors 19 and 20 as a volume regulating variable resistor is unnecessary to be detected, etc., and the voice output can be automatically generated at the set time.
