摘要

PROBLEM TO BE SOLVED: To provide an information transmitter capable of transmitting digital information encoded into an audio signal using no speaker.SOLUTION: An information transmitter 1 includes an information voice generation section for generating information voice that is digital information encoded into an audio signal and a vibration section 12 attached to a musical instrument having a resonance section. Information voice generated by the information voice generation section is supplied to the vibration section 12 and the vibration section 12 vibrates the resonance section or the voice generation section of the musical instrument by the information voice. Thus, information voice is emitted (along with performance sound of the musical instrument). The information voice generation section may mix musical sound of music with information voice to output it to the vibration section 12. Thereby, the mixing sound is emitted from the musical instrument.SELECTED DRAWING: Figure 1
