Abstract: A string mount system and method of installing guitar strings in an acoustic guitar. The string mount system includes a tonebar having a rod including a length extending from a first terminating end to a second terminating end. The tonebar includes a constant diameter extending along the length of the rod and the constant diameter is less than an inner diameter ball end of each string in a set guitar strings. The rod is located in a hole in each of the ball ends. The tonebar, with the mounted strings, is pulled against a bridge plate of the guitar. The strings are tuned to pitch. The strings are acoustically coupled to the bridge plate and to the sound board to vibrate the soundboard to produce acoustically amplified string tones.

Abstract: A foldable stringed instrument, for example in the form of a travel guitar that folds mid-neck to assume a reduced profile is described. The mid-neck folding is accomplished in a symmetrical manner about a three-part hinge located in the neck to configure the travel guitar into a reduced profile. The bridge assembly can be translated longitudinally relative to the head of the guitar to allow sufficient detensioning of the guitar strings to enable an upper portion of the neck to be folded away from a lower portion of the neck and/or body to assume a reduced profile. To deploy the travel guitar for playing, the upper portion of the neck is unfolded into alignment with the lower portion of the neck and/or body, and the bridge assembly translated longitudinally relative to the head and locked in position to allow the guitar to be tuned for playing.

Abstract: Provided is a keyboard device for which the number of parts can be reduced. The present invention is provided with: hammers rotatably linked to a chassis; keys rotatably linked to the hammer thereof; guiding pins provided to the keys and extending in the widthwise direction of the keys; and a guiding groove provided to the chassis side and into which the guiding pins are inserted. The downward displacement of the front-end sides of the keys is guided by the rotation of the hammers with respect to the chassis, and the downward displacement of rear-end parts of the keys is guided by the sliding of the guiding pins with respect to the guiding groove. This eliminates the need for links to guide the displacement of the rear-end parts of the keys, thus allowing the number of parts to be reduced.

Abstract: Provided is a keyboard device that can suppress a reduction in the operability of a key. A rear guiding member comprises a pair of guiding surfaces that, in a side view of a key, face forward and rearward and are formed along an arc that is convex toward the front. The key comprises a pair of sliding surfaces that slide against the pair of guiding surfaces. Due to this sliding of the guiding surfaces and the sliding surfaces, rotation of the key can be guided while displacement of the key in the front-rear direction is regulated. Consequently, because forward and rearward displacement of the key during key pressing can be suppressed, a reduction in operability (feeling of touch) during pressing of the key can be suppressed.
