An apparatus, system, and method for a magnetically and releaseably attachable trigger for an instrument is provided. Additionally, the trigger provides for an increased sensitivity of sound by being in direct physical contact with the surface on which it is attached.

A stringed instrument pickup with multiple selectable coils can be utilized in a system to provide a diverse range of sound characteristics from at least one moving string under tension. A first wire can be connected to a first terminal of a first bobbin body prior to the first wire being wound around the first bobbin body a first number of times and then connecting the first wire to a second terminal of the first bobbin body. A second wire may be connected to the second terminal of the first bobbin body before winding the second wire around the first bobbin body a second number of times and then connecting the second wire to a third terminal of the first bobbin body. The first bobbin body is subsequently mounted onto a stringed instrument.

An onboard electronic system and associated method enables a player of an acoustic stringed instrument to control an electronic signal for modifying and amplifying sound while playing an instrument is described. The onboard electronic system is embedded in the tailpiece and/or the chinrest portions of the stringed instrument, and includes at least one pickup, a battery-powered amplification unit and at least one controller. The method includes steps for controlling sound amplification and tonal modification onboard an acoustic stringed instrument. The steps include sensing vibration from strings with a pickup, generating an electrical signal and transmitting the electrical signal to an amplification unit via an input cable, and modifying the electrical signal in response to one or more controllers located onboard the instrument.

An apparatus, system, and method for a magnetically and releasably attachable trigger for an instrument is provided. Additionally, the trigger provides for an increased sensitivity of sound by being in direct physical contact with the surface on which it is attached.

An apparatus, system, and method for an electronic handheld musical instrument that generates electronic signals for processing by a processor-based module to generate musical sounds adapted to replicate non-electronic traditional hand percussion and other handheld instruments, is provided. A piezoelectric-based trigger is secured in an enclosed volume or enclosure formed in the electronic handheld musical instrument. When manipulated by a musician in a normal fashion, freely moving beads float or travel within the enclosure of the electronic handheld musical instrument and strike against a sensitive face of the piezoelectric transducer device to create a desired sound effect.

A single axis position transducer uses an elongate permanent three pole magnet having a radial magnetic field at a spot along the magnet in which the magnetic field has radial field lines that decay as 1/R. R is the distance from the center of the magnet along a radial field line perpendicular to the axis of the magnet. The spot has a first pole of one polarity, and the magnet has poles of the opposite polarity spaced along the magnet on opposite sides of the first pole of the radial magnetic field located at the spot. At least one magnetic field sensor is positioned proximal to the spot along the elongate member that detects the motion of the spot and electrically amplifies the sensor output.

An interchangeable pickup support is for a stringed musical instrument. The support is of the type that includes at least a base body provided with an attachment to a stringed musical instrument and a support for supporting and attaching the pickup to the base body. The attachment includes at least a fastener which is movable by an actuator which is rigidly connected to the fastener, the ends of which are configured to project in part through respective holes arranged on the outer surface of the base body and attached to the stringed musical instrument. The base body also includes at least a retainer for the fastener in the attachment to the stringed musical instrument.

A cartridge is formed of a mounting plate having a geometric configuration with an upper edge, a lower edge, a left edge, a right edge, an interior surface, and an exterior surface. A higher plate above the mounting plate has a geometric periphery with an upper edge, a lower edge, a left edge, a right edge, an interior surface, and an exterior surface. A plurality of posts couple the interior surface of the mounting plate and the interior surface of the higher plate to create a space for the receipt of at least one pickup. Two spring biased plates are mounted on the mounting plate. A coil spring separates the two spring biased plates. The spring biased plates have locking fingers reciprocally mounted on the mounting plate for engagement with locking projections on a docking ring. Each spring biased plate has a finger hole for retracting the locking fingers.

An apparatus, system, and method for a magnetically and releaseably attachable trigger for an instrument is provided. The trigger and securing device are disposed on either side of a drumhead or other instrument surface via magnetic force, keeping the instrument surface intact and not deforming the instrument surface. Additionally, the trigger provides for an increased sensitivity of sound by being in direct physical contact with the surface on which it is attached.

The invention relates to a pickup system for an electrically-amplifiable stringed instrument, comprising a carrier element for a pickup magnet of an electromagnetic pickup, wherein said carrier element is L-shaped and can be connected to a bracket, the bracket supports a coil with a secondary winding of said electromagnetic pickup, and the L-shaped carrier element and the bracket form a primary winding of said electromagnetic pickup. The invention also relates to an electrically-amplifiable stringed instrument comprising such a pickup system.
