PURPOSE:To realize tone control in which a voice output feels natural is implemented. CONSTITUTION:The characteristic is set almost flat in the tone effect band, and for example, in the case of low frequency cut, it is avoided that an attenuation level is increased toward lower frequencies. Thus, the frequency characteristic adjustment circuit 10 is provided with a filter means 11 passing a signal for a predetermined frequency band among input signals, a buffer means 12 connecting in parallel with the filter means to receive an input signal and adder means Rc, Rv adding an output of the filter means and an output of the buffer means with the adjustment of a mixing ratio to provide an output. |
