According to an aspect of the present invention, there is an electric violin comprising a sound bar having a first tang and a second tang. The central portion of the sound bar rests on a top plate of the violin, separated by a separator pad, and the first and second tangs protrude to an inner cavity of the violin through a first and a second plate hole of the top plate. A pickup assembly includes a first and a second pickup, where each of the pickups comprise a bobbin made of two plates separated by a plurality of magnetic polepieces and surrounded by a coil wire. Each of the pickups includes a compression mechanism including a height adjustment screw that holds the compression mechanism at a firm tension while the distance between the plurality of the magnetic polepieces of the pickup and the corresponding tang satisfies a tolerance gap.

The magnetic pickup positioning mechanism for electric musical instruments is mounted beneath the strings between the neck and bridge of an electric musical instrument like the electric guitar or bass. It includes a length of “C” profile track fastened to the guitar and one or more slide-swivel assemblies that twist-lock into, slide and rotate along the track. Magnetic pickups are mounted to the slide-swivel assemblies that allows the player to use their hand to slide and rotate the pickups to various positions and angles between the neck and bridge in order to get a wide variety of tones.

A musical sound generating apparatus capable of improving the sensitivity of pressing against a percussion surface is provided. The musical sound generating apparatus includes a percussion surface, a pressure sensor disposed on the percussion surface on a side of a back surface and configured to detect a pressure change, an elastic body compressed between the percussion surface and the pressure sensor, and a control device configured to output an instruction according to an output value of the pressure sensor, and the control device includes a pressing detection unit configured to detect pressing against the percussion surface on the basis of a difference between the output value of the pressure sensor and a reference value, and an updating unit configured to update the reference value at every updating time according to the output value of the pressure sensor.

An electronic wind instrument includes a breath sensor, an operating element, a speaker, and an acoustic tube. The operating element receives an instruction related to a pitch. The speaker outputs a sound based on musical performance information obtained from at least one of the breath sensor and the operating element. The speaker has an inner space therein. The acoustic tube that has an inner space therein. The inner space of the acoustic tube is continuous with the inner space of the speaker. The acoustic tube extends in a direction away from the speaker.

An instrument playing apparatus has: a movable member configured to be displaced responsive to a playing operation of a user; a detection part formed from a magnetic or conductive body and disposed on the movable member; and a filter that includes a coil. The filter has a frequency response that changes depending on a distance between the detection part and the coil, and generates a detection signal from a reference signal.

A sustaining device is described for prolonging the vibration of the strings of a stringed musical instrument, such as an electric guitar having two or three electromagnetic pickups. The pickups are all low impedance transducers that can function either as pickups or driver transducers, depending on whether they are connected to the input of the instrument pickup amplifier or to the output of the sustainer amplifier, respectively. When a transducer is being used as a sustainer driver, it cannot be simultaneously used as a pickup. Different methods of selecting transducers to function as pickups or drivers are described. The transducers, having only hundreds of wire turns instead of the usual thousands of turns for common pickups, have a flat audio frequency response that can be modified to produce a multitude of common pickup sounds by manipulating the transducer resonance frequency, bandwidth, and amplifier gain.

An electrically amplified percussive instrument has at least one tone bar having a bottom side and fundamental nodes each of the fundamental nodes defined by a channel. A permanent magnet on the bottom side of the tone bar is proximal to one of the fundamental nodes and not aligned with a location of maximum tone bar vibration. A pickup coil positioned underneath the tone bar is aligned with the first permanent magnet and in electrical communication with an amplifier.

A modular single-coil electromagnetic stringed-instrument pickup, made to mount in replacement of a standard single-coil pickup, using the similar mounting screws and springs, has a replaceable base, core, blade pole and cover. The core unit has two flat coil forms glued to a bar magnet, which together form a trough for the coil. The outsides of the coil forms have printed circuits which form the coil end contacts and an integral electrostatic shield, with interconnect fixed after the coil is wound, so that the core unit can be flipped to change the magnetic polarity of the pickup, and thus the string vibration signal, while maintaining a humbucking pair circuit with equivalent pickup. The base, which can be either non-magnetic or ferro-magnetic material in different shapes and configurations to shape the magnetic field, contains three conductive index pins, which both make contact with the core unit contacts, and transmit string signals to any circuit or electrical contacts on the bottom of the base. The bottom of the base can be endowed with printed circuits, either on the base itself, or in flexible printed circuit soldered to the index pins. An elastomer shim sits between the core unit and base to give support to the core and microphonic damping. The vertical blade pole sits on top of the core unit, embedded in a non-conductive, non-magnetic horizontal support plate, is held in place by the cover, and separate elastomer shims. The shim between the blade and core unit has a section directly under the blade filled with magnetic material to transmit the magnetic field from the magnet to the blade. The blade pole can be formed, ground or filed to different heights and shapes under the strings, so as to correct for signal strength or to affect the harmonic content of the string signal directly. By trading out the core, base and blade for different types, a wide variety of tonal characters can result, imitating several other types of pickups, as well as providing upgrades from passive pickups to those with active circuits on the base.

The present invention relates to a mixer apparatus (30) for mixing audio signals from a musical instrument (10). The mixer apparatus (30) comprises plural input circuits (34) and an audio signal mixer (36). Each of the plural input circuits (34) has an audio signal input which, in use, is coupled electrically with and thereby receives an audio signal from a different one of plural musical instrument pickups (32) comprised in the musical instrument. The audio signal mixer (36) receives audio signals from the plural input circuits (34) and mixes the received audio signals with one another. Each of the plural input circuits (34) comprises a linear active circuit in an audio signal path between the audio signal input and the audio signal mixer (36).

A reusable vibration inductor structure includes a vibration inducting sheet, Velcro tape and circular iron ring, wherein the Velcro tape of the same diameter is attached to a back of the vibration inducting sheet, the circular iron ring having a larger diameter is adapted to press against an outer rim of the Velcro tape, and an outer rim of the circular iron ring is equidistantly configured with a plurality of pressing tabs capable of being horizontally pressed back to clamp an outer rim of a front of the vibration inducting sheet with front ends thereof. Whereby, the present invention can be conveniently detached down and reattached to the surfaces of different percussion instruments.
