摘要： A musical tone control apparatus comprises a main unit and at least one detector for detecting movement of player's finger, hand and the like. The main unit can be mounted on a player's wrist by use of a belt. When plural detectors are provided for detecting movements of player's fingers, tone color, tone pitch of musical tone or key-on timing is controlled based on combination of bent fingers. In order to detect bending of each finger, a joint switch is provided for each finger. In order to prevent deviation of key-on signals, a comparator is further used for comparing the predetermined threshold value with detection value corresponding to the bending of each finger so that the key-on signal is generated when the detection value exceeds the threshold value.

摘要： The musical tone generating apparatus converts a movement of a man into a musical tone. Such movement of the man includes a walking or running movement, a jumping movement, a rubbing movement and a beating movement, a turning movement and the like. More specifically, a tone pitch, a tone color, a tone volume or other parameters of the musical tone to be generated is controlled based on a value of a moving speed, a value of a jumping height or a value of frictional heat produced by the rubbing movement of player's hands.

摘要： A keyboard apparatus of an electronic musical instrument includes keys, mass members, and springs. Each key can pivot about a first pivot fulcrum. Each mass member can pivot about a second pivot fulcrum. Each spring supplies a biasing force to at least the corresponding mass member so that the mass member returns to an initial state. In this apparatus, each key has a point of application for pivoting the corresponding mass member in the same direction as a pivoting direction of each key when each key is depressed.

摘要： A keyboard apparatus for an electronic musical instrument is arranged that a return spring provided on each key for imparting the key a returning habit from a depressed state is comprised of either a leaf spring, a coil spring or a rod-like spring which is compressed lengthwise to be used in a buckling-deformed state, whereby warping of the spring is minimized, and the spring is allowed to progressively increase its curving after once developing the buckling without the need of increasing the compression load, thereby progressively reducing the reaction force of the spring. Thus, as the key is depressed deeper, there is obtained a lighter sense of key touch, and thereby a key touch resembling that of a piano is obtained.

摘要： A keyboard assembly for a keyboard instrument such as an electronic piano is constructed using a key, a first moving member, a second moving member and a key-depression switch. Herein, the key is supported by a keyboard frame to have a capability of rotating up and down about a rotation center. The first moving member is arranged beneath the key and is subjected to rotary motion about a first rotation center. The second moving member incorporating a deadweight has a larger weight and a longer moving distance as compared with the key and first moving member respectively. At the key depression, mode a back portion of the first moving member rotates upwardly so that the second moving member normally located at a rest position is subjected to rotary motion about a second rotation center. Thus, the second moving member rotates backwardly, and, it is stopped at a contact position defined by a back portion of the keyboard frame. Thereafter, the second moving member is subjected to back checking by which the second moving member is slightly moved forward and is temporarily fixed in position as long as the depression of the key is maintained. The key-depression switch is located beneath the key and is turned on to produce a musical tone in response to the depression of the key.

摘要： A keyboard musical instrument includes a plurality of keys mounted on a casing in juxtaposed relation. Each of the keys has a retaining portion engageable with a key stop portion on the casing to limit the upward movement of the key. A resilient leaf is formed integral with each key and extends rearwardly therefrom. The resilient leaf nomally urges each key into its raised position. The resilient leaf has an engaging section at its rear portion. The engaging section is detachably retained in a retaining groove formed on the casing. A guide surface is formed on the casing immediately adjacent to and forwardly of the retaining groove for facilitating the insertion of the engaging section into the retaining groove.

摘要： A keyboard apparatus has a support member and a plurality of white keys and black keys. Each of the white keys and the black keys has a fulcrum section and a driving section, and are pivotally mounted about the fulcrum section with respect to the support member. A mass body assembly, that is an action member, has a moving fulcrum, a driven section on a first side of the moving fulcrum that is driven by each of the driving sections of the white keys and the black keys, and a center of gravity that is located on a second side opposite the driven section with respect to the moving fulcrum. The distance between the driven section and the moving fulcrum of the mass body assembly for the black key is greater than the corresponding distance for the white key. The mass body assembly on the second side is formed from the same members that are commonly used for both the white keys and the black keys.

摘要： A keyboard apparatus has a first frame (support member), and a keyboard including a plurality of white keys and black keys, each of the keys having a fulcrum and movably about the fulcrum with respect to the support member. Each of the black keys has an extension section connected to one end of each of the black keys. The extension section extends under operation sections of two adjacent white keys toward the free ends of the white keys. A white key driving section is provided adjacent to a free end portion of each of the white keys. A black key driving section is provided adjacent to a free end portion of each of the extension sections. The white key driving sections and the black key driving sections are located at substantially the same distance from their respective fulcrums, and drive movable sections such as mass body assemblies (action members) or key switches that are operated in association with the corresponding white keys and the black keys.
