A modulated electromagnetic musical instrument and sound reproduction system includes an acoustic carrier signal source, a modulation signal source, a linkage element, and an acoustic output. The acoustic carrier signal source is produced electromagnetically or mechanically via human instrument playing. An electromagnetic modulation source mixes with the acoustic carrier signal within a linkage element to produce a nonlinear behavior. This nonlinear behavior's coupled interaction with a physical medium or acoustic body produces sideband frequency components to form unique musical sound outputs and audio effects.

The present invention provides an acoustic apparatus which can be attached to the musical instrument without adding processing to reproduce. After the acoustic apparatus is detached, the user can enjoy playing the musical instrument itself same as before the acoustic apparatus is attached. An acoustic apparatus 1 has a vibration generator 2, a support body 3, a locking portion 4 and a drive circuit 5. The acoustic apparatus 1 is locked to a neck holder 301 of a stand 300, and a diaphragm 201 of the vibration generator 2 is arranged to face a sound hole 109 of a guitar 100. The drive circuit 5 drives the vibration generator 2 according to the inputted sound signal to resonate a sound box 103. Thus, rich sound can be reproduced.

At least one electronic signal is converted into at least one electromagnetic field, where the electronic signal may be created or modulated by environmental, interactive, and programmed inputs. The at least one electromagnetic field vibrates a ferromagnetic element creating an acoustic sound and optionally a transducer converts the vibration into an electronic signal for processing.
