請求の範囲第１項記載の音域拡大装置。[Claims for Utility Model Registration] (1) A first bandpass filter that extracts a predetermined range signal from an input signal, a frequency converter that converts the output signal of the first bandpass filter to a predetermined frequency, and Sound range expansion characterized by comprising a second bandpass filter that removes unnecessary signal components from the output signal of the frequency converter, and an adder that adds the output of the second bandpass filter and the input signal. Device. (2) The first band-pass filter was composed of a band-pass filter that extracted mid-high frequency range signals, and the frequency converter was composed of a multiplier that multiplied the output signals of the first band-pass filter. A range expanding device according to claim 1 of the utility model registration claim. (3) The first bandpass filter is composed of a bandpass filter that extracts mid-high range signals,
The frequency converter is comprised of an inverter that obtains an inverted signal of the output of a first bandpass filter, and a pair of diodes that obtains a pulsating signal from the output of the first bandpass filter and the output of the inverter. The sound range expansion device according to item 1. (4) The first bandpass filter is composed of a bandpass filter that extracts a low frequency signal, and the frequency converter performs detection using the output signal of the first bandpass filter and a signal whose phase is inverted. positive and negative full-wave pulsation signals are generated respectively, and the signals are sent out alternately at the timing when the output of the first bandpass filter is divided by 1/n (n is an integer of 2 or more). A range expanding device according to claim 1 of the utility model registration claim.
