A stringed instrument, in accordance with some embodiments, has an instrument body physically supporting a bridge base beneath a plurality of strings with the bridge base constructed with a groove in which a tone plate and saddle are each positioned. The saddle has an articulation mechanism positioned wholly outside of an areal extent of the plurality of strings while contacting the saddle. The articulation mechanism is arranged to contact the tone plate to support the saddle during movement of at least one of the plurality of strings.
Various embodiments of a stringed instrument bridge assembly consists of a bridge base attached to an instrument body beneath a plurality of strings with the bridge base having a groove aligned with the plurality of strings. A saddle is positioned within the groove of the base bridge to contact each of the plurality of strings. The saddle has a first articulation mechanism and a second articulation mechanism that are each positioned wholly external to an areal extent of the plurality of strings while a tone plate is positioned between the saddle and instrument body within the groove in the bridge base. The tone plate constructed of a rigid material that physically contacts each articulation mechanism.
In other embodiments, a tone plate is positioned within a groove of a bridge base that is attached to an instrument body prior to a saddle being positioned within the groove, atop the tone plate. The saddle is configured to contact and tension each of a plurality of strings to produce a predetermined sound upon selection of at least one of the plurality of strings. A height of the saddle relative to the instrument body is then adjusted with at least one articulation mechanism of the saddle. Each of the articulation mechanisms positioned wholly outside an areal extent of the plurality of strings to allow the height adjustment without moving the plurality of strings.
Embodiments of the present disclosure are directed to a stringed instrument bridge that allows for efficient and accurate saddle height adjustment while providing a low-profile bridge height.
A stringed instrument suspends at least one tensioned string over an electrical pickup and/or sound port that distributes sound electrically and/or acoustically. While the suspension of a string to generate musical sound can be facilitated in numerous, diverse manners, string intonation is controlled by contacting the string proximal to where the string will be plucked, or stroked. Such string contact can be configured to be a saddle, bridge, or both that aid in maintaining tension on the string, transferring string vibration, and space strings apart from one another.
It is contemplated that a saddle/bridge can be adjusted for height away from an instrument body to allow for manipulation of the action of the strings, vibration, and intonation. However, conventional adjustment of a bridge/saddle in a vertical direction can be bulky, imprecise, and/or inaccurate due to the configuration of the adjustment mechanisms. Thus, a continuing goal for stringed instrument construction is the improvement of the structure and function of a bridge/saddle that provides efficient vertical adjustment corresponding with accurate string action and vibration. Assorted embodiments of a bridge assembly are herein described to meet this industry and consumer goal.
Accordingly, some embodiments of a bridge position a tone plate in a groove of a bridge base between the bridge base and a saddle. The configuration of the saddle and groove allow the saddle to be vertically adjusted with mechanisms that do not add bulk or height to the overall bridge assembly. The positioning of the saddle adjustment mechanisms outside the areal extent of the strings allows the saddle to be adjusted efficiently and without loosening strings, dislocating the bridge, or moving an electronic pickup. As a result, the bridge can have a relatively low-profile height that provides stability and strength to optimize instrument tone, string vibration, and string intonation. It is noted that a bridge, in various embodiments, can be configured as a floating bridge or a fixed bridge.
A block representation of an example stringed instrument 100 is conveyed in
In some embodiments, each string 106 can have dynamic tension provided by tuning pegs of the neck 104, or head portion of the neck 104. String 106 tension may further be facilitated by physical string adjustment in a bridge 138, tailpiece 140, and/or saddle 108. It is noted that no string adjustment configuration is required, or limiting, but a string 106 can have multiple separate components contacting the string 106 with capabilities to adjust the position, tension, and/or height of the string 106 relative to the guitar body 132. It is noted that while the saddle 108 is shown as part of the bridge 138, such configuration is not required and the saddle 108 can be physically separated from the bridge 138 atop the guitar body 132.
The cross-sectional view of
The size and position of the respective dials 156 can further limit the position of a pickup 136 on the guitar body 132. That is, a pickup 136 cannot be positioned too close to the bridge base 158 to inhibit dial 156 rotation, which limits the tone capability of an electric guitar. As a result of the dial-type bridge 150 shown in
The adjustment mechanisms 178 may be any assembly that allows vertical movement of the saddle 176 with respect to the bridge base 172, along the Z axis, while securing the saddle 176 in response to string articulation and vibration. In other words, any mechanism, and any number of mechanisms, can be used in the saddle 176 that provides an acoustically secure contact for the various strings while allowing for tuning of the saddle height upon articulation of the adjustment mechanisms 178. In some embodiments, each adjustment mechanism 178 is a threaded screw that can be turned by hand, or tool, to manipulate the position of the saddle 176 above the bridge base 172.
It is noted that the position of the respective adjustment mechanisms 178 is separated from the string regions 180 along the X axis. Such positioning allows for easy and efficient access to the mechanisms 178 when strings contact the string regions 180 without having to loosen the strings, move the bridge base 172, or move any adjacent electrical pickups. The positioning of the adjustment mechanisms 178 further allow the bridge 170 to have a lower profile than dial-type saddle adjusting assemblies, as shown in
Through the configuration of the string regions 180 and adjustment mechanisms 178 of the saddle 176, string height above an instrument body can quickly be adjusted while the strings remain at playable tension and intonation thanks to the customized aspects of the string regions 180. That is, the relatively low profile of the saddle 176 along with the rounded, notched, pointed, and/or grooved string regions 180 corresponds with efficient access to the adjustment mechanisms 178, such as with a user's hand or tool, as well as efficient vertical movement of the saddle 176 without having to move the bridge base 172 or any pickups of the musical instrument. The relatively low profile of the bridge 170 further allows it to be utilized in solid body guitars and other instruments that have a low string height, which may be associated with a relatively low pitch neck angle.
The exploded view of the bridge 170 in
Where a tone plate 184 is positioned between the saddle 176 and the bottom surface of the groove 174, the adjustment mechanism posts 182 do not contact the bridge base 172, or instrument body, directly and, instead, engage the tone plate 184, which has a size, shape, and material that optimizes instrument tone by absorbing pressure from the saddle 176 and distributing string vibration to the instrument body more thoroughly. It should be appreciated that the saddle 176 of various embodiments can be provided with a base having a groove, without a bridge base, or placed in a groove of the instrument body. It is noted that the tone plate 184 is optional, but may be useful where a bridge base, or instrument body, consists of a groove composed of wood, or other material, that a screw adjustment mechanism would potentially pierced through use over time.
The expansion of the components of the bridge assembly 170 in
It is contemplated that the tone plate 190 has one or more relief regions 196, such as, but not limited to, indentions, recesses, holes, grooves, or surface textures to tune how the acoustic properties of a moving string are translated by the tone plate 190 to a bridge base. Some embodiments configure the tone plate 190 with two different surface configurations, as generally displayed by the comparative textures of regions 198. The top 200 and bottom 202 surfaces of the tone plate 190 may also be constructed with different surface shapes, textures, and configuration that exhibit different acoustic energy transfer characteristics that allow a user to customize the tone and acoustic properties of the instrument simply by flipping the tone plate 190 over inside the bridge base groove 174.
While not part of the stringed instrument 210, an example tool 220 is shown in
With the saddle 214 being recessed into the bridge base 228 and configured with recesses 216 that can be uniquely tuned to provide different intonations, string vibrations, string action, and string control for the respective strings 106, the bridge 212 can present the strings 106 with a relatively low height 230 above the instrument body 132 along with the pickup 226. The low string height can be adjusted by a user at any time without altering the playability of the instrument 210 thanks to the adjustment mechanisms 222. It is contemplated that multiple, separate adjustment mechanisms 222 are provided by the saddle 214 and can be individually, or collectively, articulated to provide fine resolution tuning of the string height 230, such as between strings 106 on the extreme lateral sides of the saddle 214.
As discussed above, the saddle 214 can have a base itself with a groove, may be provided without a bridge base, and may be placed in a groove of an instrument body. It is reiterated that the tone plate is optional, but may be useful when a bridge base, or instrument body, has a groove constructed of a material that can be pierced over time through engagement with a saddle adjustment mechanism.
In some embodiments, construction of the floating bridge allows step 244 to position strings in contact with the saddle, which corresponds with tensioning the respective strings with one or more tensioners arranged throughout the instrument. At least one string is played in step 246 to test the action and height of the string as well as the tone of the instrument. Such playing may be facilitated by hand and/or with a tool, such as a pick or bow. Decision 248 then determines if a saddle adjustment is in order based on the results of step 246. If so, step 250 proceeds to change one or more characteristics of the saddle, which may involve manipulating one or more adjustment mechanisms, flipping a tone plate, or reversing the orientation of the saddle in the groove. As a result of such adjustment in step 250, a user can customize multiple different aspects of the feel and acoustic characteristics of the strings, and instrument as a whole.
The tuned configuration of the instrument, or in the event no saddle adjustment was necessary from decision 248, advances routine 240 to step 252 where the string(s) are played to generate music that has the tuned tone and intonation afforded by the bridge. The ability to revisit step 250 any number of times to provide different instrument tuning without having to temporarily eliminate the playability of the instrument allows for efficient optimization of the strings, tone, and instrument as a whole.
The orientation plate 266 is configured with slots 268 that are each partially filled with a fastener 270 that can be tightened to secure the orientation plate 266 in the X-Y plane. For instance, the respective slots 268 can be sized to allow the orientation plate 266 to rotate in the X-Y plane relative to the strings 106. As a result, the physical engagement of the respective string regions 180 with the respective strings 106 can be tuned and controlled to manipulate the acoustic properties of the strings 106 when struck by a user. The combination of the ability to manipulate height of the saddle 214 relative to the instrument body 132 along with the orientation of the string regions 180 allows for precise control of acoustic string properties as well as a dynamic range of tuning options.
It is noted that the bridge assembly 262 positions the saddle 214 so that each articulation mechanism 222 is positioned outside of an areal extent 272 of the collection of strings. As shown, the saddle 214 continuously extends along a longitudinal axis (X Axis) to present each articulation mechanism 222 wholly external to the strings 106 and accessible without moving, loosening, or removing any string 106.
Although not limiting, the example assembly 262 embodiment of
The secure retention of the respective strings 106 is complemented by one or more attachment apertures 284 that can be filled with mechanical or chemical fastening materials that reliably connect the tailpiece 224 to a designated location on an instrument body 132. With many stringed instruments relying on relatively high string tension during use, the ability to secure the respective strings 106 to the tailpiece 224 as well as the tailpiece 224 to the instrument body 132 provides optimal instrument consistency, reliability, and performance. It is noted that the tailpiece slots 280, as compared to holes, allows for the strings to be positioned closer to the instrument body than with traditional tailpieces. Advantageously, tailpiece 224 can have a very low profile, similarly to the bridge assembly 262, thus allowing sufficient string down force on the bridge.
The various aspects of the bridge assembly 262 can be contrasted to adjustable bridges that utilize mechanisms positioned inside the areal extent of the instrument strings, as generally shown in
The ability to employ a tool to alter the vertical position of the saddle, along the Z axis, as shown in
In some embodiments, string regions 180 may be calibrated and need no adjustments over time. For example, if one or more strings are replaced with strings having a different gauge such that intonation need to be slightly corrected or adjusted, it can be done without removal of strings by using only two adjustments screws and moving the “slide” positioning the saddle. It is contemplated that the saddle may be adjusted along a Z axis by about ¼ inch in some embodiments.
