System and method for sound augmentation of acoustic musical instruments

摘要

A sound capture device is affixed to an acoustic instrument to capture the natural sound output of the instrument. The captured sound signal is routed to an electronic sound augmentation system that is configured to augment the captured sound with spatial sound effects such as reverb, echo, delay, etc. The processed and augmented sound is then reproduced via a vibrating driver that has been affixed to the body of the acoustic instrument. This creates a situation where the body of the musical instrument, responding to a series of vibrations produced by the vibrating driver, acts as a speaker component, reproducing a rich augmented sound output that comprises the sum of the sound produced by the original sound production capabilities of the acoustical instrument plus the added augmented or enhanced sound effects.

主权项

1. A sound augmentation system comprising:
an acoustic instrument; a sound capture device attached to a flat surface of the acoustic instrument by an attachment mechanism, the attachment mechanism comprising a magnetic pad affixed to the flat surface of the acoustic instrument, the attachment mechanism providing for selective attachment and removal of the sound capture device by magnetic attraction wherein the sound capture device captures a first sound produced by the acoustic instrument, the sound capture device comprising:
an input source connection communicatively coupled to the sound capture device;an audio signal router communicatively coupled to the input source connection, the audio signal router receiving a digital audio signal from the sound capture device;a digital signal processor communicatively coupled to the audio signal router;an amplifier communicatively coupled to the digital signal processor;a vibrating driver coupled to the amplifier by one of an electronic cable and a wireless connection and receiving a digital signal from the amplifier; anda battery electrically connected to each of the audio signal router and the digital signal processor and the amplifier and wherein the vibrating driver is positioned to selectively contact the flat surface of the acoustic instrument and create a vibration of the surface of the acoustic instrument based on the digital signal received from the amplifier to produce an augmented audio signal.
