PURPOSE: To provide the sound source acoustic device of the electronic musical instrument which generates a sound like a natural musical sound by utilizing the natural resonant radiation sound of a natural stringed musical instrument unlike a piston vibratory electroacoustic transducer for air like a conventional speaker. CONSTITUTION: This sound source acoustic device for the electronic musical instrument has a sound source system having the electroacoustic transducer 10 which has an electromagnetic driving unit fitted between a fixed part and a plate type vibrator, an electric signal storage means 2 which stores an electric waveform signal corresponding to both the ends of the main resonant string of the stringed musical instrument or the string end vibrator driving force on the side of a main resonant vibrator, and a waveform signal recording means 1 which records an electric signal corresponding to a sound pressure signal, and an equalizer 4 which has a transfer function having opposite characteristics from input/output transmission characteristics of the electroacoustic transducer 10, and reproduces the sound of the natural stringed musical instrument faithfully by applying the recording signal to the electroacoustic transducer 10 through the equalizer 4. |
