Resonance sound producing part, has oscillation circuits whose modified signal is added to original signal in weak form when resonance produces strong delay of original signal such that fine sound is produced
The sound producing part has oscillation circuits inserted into an amplifying apparatus for increasing duration of sound with frequency within a bandwidth of the oscillation circuits. A signal modified in the oscillation circuits is added to an original signal in weak form when resonance produces strong delay of the original signal such that fine sound is produced. An inductor (L1) and a capacitor (C1) form a parallel oscillation circuit, and a resistor (R1) decouples the parallel oscillation circuit from an input.
