As a factor to characterize the sound of an electric guitar, it is thought that a characteristic of the pickup contributes most. The pickups most often used are classified roughly into single-coil models and humbucking models. The single-coil pickup is made by winding the thin wires with several thousand turns of coils around six polarizing pole pieces each corresponding to a string of the guitar, and the change in the magnetic reluctance owing to the string vibration that causes the change in the magnetic flux is transformed into an electrical signal. The humbucking pickup is composed of one

An electric guitar is composed of a wooden body, a wooden neck, an electromagnetic pickup, 6 steel strings and other electric parts. The electric guitar changes string vibration into an electric signal with the electromagnetic pickup, and the sound is emitted through an amplifier. Usually, high density and high stiffness wood is used for a body material, to prevent vibration transmission from a string to a body. Then, string vibration sustain longer and the sound remains. Also, it is reported that the material of a body influences the quality of the sound. In previous study, vibration energy p

An electric guitar is composed of a wooden body, a wooden neck, 6 steal strings and other electric parts including an electromagnetic pickup. An electric guitar convert string vibration into electric signal through a pickup, and the sound is emitted with an amplifier, or a speaker. Usually, high density and high stiffness wood is used for body material to sustain string vibration longer and the sound remains. Also, it is reported that the material of a body influences the quality of the sound. Nonetheless, there are few studies focused on detail of vibration propagation between string vibratio

guitar is classified as a chordophone, meaning the sound is produced by a vibrating string stretched between two fixed points. Historically, a guitar The guitar is a stringed musical instrument that is usually fretted (with some exceptions) and typically has six or twelve strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A guitar pick may also be used to strike the s Arc… Pickups are transducers attached to a guitar that detect (or "pick up") string vibrations and convert the mechanical energy of the string into electrical energy. The resultant electrical signal can then be electronically amplified. The most common type of pickup is electromagnetic in design. These contain magnets that are within a coil, or coils, of copper wire. Such pickups are usually placed directly underneath the guitar strings. Electromagnetic pickups work on the same principles and in a similar manner to an electric generator. The vibration of the strings creates a small electric current in the coils surrounding the magnets. This signal current is carried to a guitar amplifier that drives a loudspeaker. Traditional electromagnetic pickups are either single-coil or double-coil. Single-coil pickups are susceptible to noise induced by stray electromagnetic fields, usually mains-frequency (60 or 50 hertz) hum. The introduction of the double-coil humbucker in the mid-1950s solved this problem through the use of two coils, one of which is wired in opposite polarity to cancel or "buck" stray fields. The types and models of pickups used can greatly affect the tone of the guitar. Typically, humbuckers, which are two magnet-coil assemblies attached to each other, are traditionally associated with a heavier sound. Single-coil pickups, one magnet wrapped in copper wire, are used by guitarists seeking a brighter, twangier sound with greater dynamic range. Modern pickups are tailored to the sound desired. A commonly applied approximation used in the selection of a pickup is that less wire (lower electrical impedance) gives a brighter sound, more wire gives a "fat" tone. Other options include specialized switching that produces coil-splitting, in/out of phase and other effects. Guitar circuits are either active, needing a battery to power their circuit, or, as in most cases, equipped with a passive circuit. Fender Stratocaster-type guitars generally have three single-coil pickups, while most Gibson Les Paul types have humbucker pickups. Piezoelectric, or piezo, pickups represent another class of pickup. These employ piezoelectricity to generate the musical signal and…

The electromagnetic pickup of an electric guitar is a nonlinear device that provides a pleasant distortion. Although the pickup is a simple device consisting of a coil and a few magnets or pole pieces, the measurement of its nonlinear function is a difficult task. This paper shows a measurement technique that can estimate the nonlinear function of a pickup in both y− and z− directions of the vibrating string. The experimental results are provided for three different types of pickups: a single-coil pickup with six staggered pole-pieces, a humbucker pickup with six equal height pole-pieces, and

This paper presents the Digitl, a digital processing system using a reduced electric guitar as control input. The physical design is based on three fundamental elements: String, Body and Electromagnetic Pickup. The main characteristic of the instrument lies is the linear matrix x-y configuration of the strings and frets. The purpose of the instrument is the application of individual signal processing at each X-Y position. It is described the technical aspects of the Digitl, including the design of the matrix configuration and the digital signal processing algorithms. Specifically, a set of Max

When deriving the equation describing the transverse motion of a one-dimensional vibrating elastic string, introductory physics textbooks often assume constant tension and/or small amplitude vibrations. However, these simplifying assumptions are not only unnecessary, but they overlook the elastic nature of the tension and yield an inconsistent derivation of the potential energy density. Because of these assumptions, the derivation of the wave equation and the potential energy density use two different levels of mathematical approximation. In addition, students often get confused as of how a st
