A string tensioner is configured to apply a substantially constant tension to a string over an operational range even if such string stretches and contracts over time. Tension is provided by a spring. Flexers can attach the spring to a force modulation member and a frame. The flexers preferentially bend out-of-axis so that the spring does not bend out-of-axis when the force modulation member rotates. A dampening system can slow the force modulation member's response to vibrational forces. A flexible stop can prevent rotation of the force modulation member beyond a desired point, but flexes to remain in contact with the force modulation member over a small range of movement.

String tensioner for musical instrument

A low-friction bridge for a stringed musical instrument employs a roller saddle that is adapted and positioned to roll upon a race. The race includes structure to guide the roller saddle as it rolls. A musical string is seated in a circumferential groove/saddle formed in the roller saddle. As the musical string stretches or contracts the saddle rolls, and thus the musical string does not slide in the saddle. As such sliding friction is avoided in favor of rolling friction of the roller saddle rolling upon the race. One or more contact members can be biased into contact with side faces of the roller saddle.

Low-friction bridge for stringed instrument

A string tensioner module for a stringed musical instrument is configured to apply a constant or near-constant tension to the musical strings of the instrument. The module is divided into a plurality of string tensioners, one string tensioner for each musical string. Each string tensioner employs a primary spring that apply the primary force coaxial with the string. Each string tensioner also employs a secondary spring that applies a secondary force in a direction crossing the axis of the string, and thus applying an axial force component that changes as the angle of the secondary spring changes. The primary and secondary springs are selected so that the change in the axial force component of the secondary spring as the string changes in length approximates the change in force applied by the primary spring so that the axial force applied to the string remains generally constant even as the string changes in length.

String tensioner for stringed instrument

A support is configured to support and apply a constant or near-constant tension onto a wire or string, such as a musical string of a stringed musical instrument. The wire is attached to a carrier that moves axially. One or more springs operate between the carrier and a point that is fixed relative to the carrier and apply a transverse spring force to the carrier. A spring angle is defined between a line normal to the axis and a line of action of each spring. The transverse spring force can have an axial force component and an axial spring rate that is a function of the spring angle. The carrier can be positioned so that the axial spring rate is zero, negative or positive. A primary spring can apply a primary force directed coaxial with the wire. If the wire changes in length the primary force will correspondingly change, as will the axial force component. The transverse spring can be selected so that the axial force component of the transverse spring approximates the change in the force applied by the primary spring so that the axial force applied to the carrier and wire remains generally constant.

Constant tension device

A tensioner for a string on a stringed musical instrument is provided. The tensioner can include an elongated body, at least two spring modulation members, a spring modulation support, and at least one spring. Each of the spring modulation members have a first portion pivotably attached to a portion of the elongated body. The spring modulation support is pivotably attached to a second portion of each of the spring modulation members. The spring is interposed between the elongated body and the spring modulation support.

Stringed musical instrument using spring tension

A stringed musical instrument employs springs to apply tension to corresponding musical strings. Each spring is chosen and configured for its ability to impart a string tension generally matched to the appropriate tension of the string at perfect tune. Preferably, the spring is selected and arranged so that the tension in the string maintains at or near perfect tune even as the string elongates or contracts over time. In one embodiment, once a string is placed in appropriate tune, a mechanical visual indicator is set. As such, if tune of the string changes due to string elongation or contraction, the change is reflected by misalignment of the mechanical visual indicator even if the change cannot be aurally detected. Perfect tune can be reestablished by realigning the indicator. In another embodiment, a force modulating member is interposed between a spring and its corresponding musical string. The force modulating member is adapted so that the tension actually applied to the string by the spring is not linearly related to the force exerted by the spring as the spring changes in length.

A stringed musical instrument employs string tensioners to support and apply tension to corresponding musical strings. Each musical string is supported by one string tensioner, and each of the string tensioners is linearly movable independent of others of the string tensioners. Further, an adjustment mechanism is provided for selectively linearly moving each string tensioner. In a preferred embodiment, an effective playing length of each string is defined between the associated string tensioner and the nut of the instrument. As such, individual linear adjustment of the string tensioners enables the user to vary the playing length of the associated musical string. In other embodiments, a string tensioner is provided that supports a musical string from a position on a side of the string opposite the associated musical instrument surface.

Modular bridge for stringed musical instrument

A stringed musical instrument employs springs and/or one or more hanging masses to apply tension to corresponding musical strings. Each spring and/or mass is chosen and configured for its ability to impart a string tension generally matched to the appropriate tension of the string at perfect tune. Preferably, the spring and/or mass is selected and arranged so that the tension in the string maintains at or near perfect tune even as the string elongates or contracts due to environmental factors or passage of time.

Stringed musical instrument

A stringed musical instrument includes a string mounting arrangement that enables multiple strings to be maintained in relative tune as the pitch of the strings is simultaneously varied. In one embodiment, a composite musical string comprises multiple segments, each segment having a different density, but the composite string will maintain substantially the same tension throughout its length. As the tension is increased or decreased, the pitch of the instrument changes, but the relative tuning between the strings remains. In another embodiment, a composite string comprises musical string segments joined end-to-end with bending segments. The musical segments are adapted to emit desired notes and tones at tension. The bending segments are adapted to easily bend about pivots such as a tuning knob or pulley.
