Title:
SOUND REPRODUCING DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2009/149634
Kind Code:
A1
Abstract:
A sound reproducing system includes a string instrument (60), a pickup (30) mounted on the string instrument, a sound recording and reproducing device (908) electrically connecting with the pickup, an amplifier (404) electrically connecting with the sound recording and reproducing device, an actuator (20) and a resonant body (50). Sound is sensed and converted to an audio output signal by the pickup (30). The audio output signal is recorded and reproduced by the sound recording and reproducing device (908) which outputs an audio input signal. The audio input signal is amplified by the amplifier (404) to produce an amplified audio input signal. Mechanical vibration is generated by the actuator (20) mounted on the resonant body according to the amplified audio input signal. Based on the mechanical vibration, resonance is produced by the resonant body (50), which serves as a sound output device for producing sound.
