Abstract: The present disclosure relates generally to a drum apparatus with advanced acoustic response and methods of manufacturing the drum apparatus. The drum apparatus includes an integral drum body having a side wall defining a resonant chamber. The integral drum body is formed by an additive manufacturing process or with a volume printing material that shapes the side wall to define an acoustic response of the drum apparatus. The side wall is shaped to define a top perimeter region and a bottom region of the integral drum body. The top perimeter region defines a top opening to the resonant chamber and the bottom region defines a bottom of the resonant chamber, opposite the top perimeter region. The side wall has a thickness or mass distribution controlled by the additive manufacturing process or defined by the volume printing material to modulate the acoustic response of the drum apparatus.

Abstract: A snare unit formed from film material includes a plurality of slots that define segments. The snare unit is attachable relative to a drumhead with a surface of the film flat against a surface of the drumhead. In the attached position, one or more of the segments vibrates against the drumhead when the drumhead is struck to produce a snare-like audible sound. In a drumhead with reduced volume, the snare unit is positioned flat against one or more layers of a porous material to define a drumhead and attached such that a portion of the snare unit vibrates against a surface of the porous material when the drumhead is struck, thereby producing a snare-like sound having a volume reduced relative to a standard drumhead.

Abstract: The present invention provides a sounding control system capable of performing high-accuracy crosstalk suppression while reducing the processing load on a sound source device. When a first pad (12) vibrates, the first pad (12) generates sound emission data (62a1) that is information instructing a sound source device (11) to produce a sound and crosstalk cancellation determination data (62a2) that is information used for canceling crosstalk, and sends the data to the sound source device (11). The sound source device (11) determines whether or not crosstalk has occurred and controls sound emission using the information.

The mid-neck folding is accomplished in a symmetrical manner about a three-part hinge located in the neck to configure the travel guitar into a reduced profile.

To deploy the travel guitar for playing, the upper portion of the neck is unfolded into alignment with the lower portion of the neck and/or body, and the bridge assembly translated longitudinally relative to the head and locked in position to allow the guitar to be tuned for playing.
