JP2017003890A - Shoulder keyboard - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a shoulder keyboard which can be easily played by using both hands.SOLUTION: A shoulder keyboard 1 comprises a right hand keyboard 1R and a left hand keyboard 1L, in a manner in which playing hand directions are opposite each other, and orientations of a treble direction to the playing hand direction of the right hand keyboard 1R and the left hand keyboard 1L are opposite each other. A user can naturally extend both hands to the keyboards, and the treble directions on the keyboards are same, so that a user does not feel discomfort. In addition, if a depression depth of the left hand keyboard 1L is set to almost 7 mm and a depression depth of the right hand keyboard 1R is set to almost 10 mm, slide playing can be performed easily.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a shoulder keyboard.

  As a keyboard portion of an electronic keyboard instrument, a shoulder keyboard (see, for example, Patent Document 1) is known in which a shoulder strap is used to hang from a shoulder and a keyboard is operated in front of the body like a guitar.

  The conventional shoulder keyboard has only one keyboard as disclosed in Patent Document 1. Therefore, when playing with both hands, both hands will be placed between the keyboard suspended from the shoulder and the player's body, and the appearance of the player (such as the player's pose) will be improved. It wasn't always good. Therefore, it was often performed with only one hand (for example, the right hand).

  On the other hand, if you can perform with both hands, the range of musical expression will be expanded. It is also possible to produce different timbre sounds for the right hand and the left hand.

Japanese Utility Model Publication No. 06-055195

  An object of the present invention is to provide a shoulder keyboard that can be easily played using both hands.

The shoulder keyboard of the present invention is
A right-hand keyboard and a right-hand keyboard with a left-hand keyboard whose playing direction is opposite;
The direction of the treble direction of the right hand keyboard and the left hand keyboard is opposite to the player direction.

  According to this feature, the right hand and the left hand can operate different keyboards and perform using both hands. Further, the right hand and the left hand are opposite to the performer direction, but the treble direction is the same. It is easy to play.

The shoulder keyboard of the present invention is
The right hand keyboard has a high pitch direction on the right side with respect to the player direction,
The left hand keyboard is characterized in that the left side with respect to the player direction is the high pitch direction.

  According to this feature, the right side of the performer is easy to understand in a normal usage in which the right hand is extended from above the shoulder keyboard and the left hand is extended from below the shoulder keyboard.

The shoulder keyboard of the present invention is
The pressing depth of the left-hand keyboard is shallower than the pressing depth of the right-hand keyboard.

  According to this feature, it is possible to easily perform the so-called slide performance method in which the hand (or tool) is moved on the keyboard. Also, the burden on the left hand can be reduced by other than the slide playing technique.

The shoulder keyboard of the present invention is
The depressed depth of the left-hand keyboard is approximately 7 mm, and the depressed depth of the right-hand keyboard is approximately 10 mm.

  According to this feature, the pressing depth preferred by many players is obtained.

  According to the present invention, it is possible to provide a shoulder keyboard that can be easily played using both hands.

FIG. 1 is a diagram showing a shoulder keyboard. FIG. 2 is a diagram for explaining the depression depth of the keyboard.

  FIG. 1 is a diagram showing a shoulder keyboard. The shoulder keyboard 1 includes a right hand keyboard 1R, a left hand keyboard 1L, and a control device 2. Performances of the right-hand keyboard 1R and the left-hand keyboard 1L (information on pressed keys) are transmitted from the control device 2 to a sound generator (not shown), and sound is output by the sound generator. In the control device 2, the pitch and tone of the right hand keyboard 1R and the left hand keyboard 1L may be set.

  The figure shows the state where the shoulder keyboard is used as seen from the front of the performer. That is, using a shoulder strap (not shown), the shoulder keyboard 1 is hung on the shoulder, and the right hand 3R is extended from above and the left hand 3L is extended from below. Although the usage of the shoulder keyboard 1 is not limited to this arrangement, this arrangement is typical.

  The right hand keyboard 1R has a high pitch on the left side of the drawing (right side as viewed from the performer) indicated by a white arrow in the figure. The high-pitched sound direction is on the right side with respect to the player direction, and has the same key arrangement as that of a widely used keyboard.

  On the other hand, the left hand keyboard 1L has a treble on the left side of the drawing (right side as viewed from the performer) indicated by the black arrow in the figure. The left side with respect to the player direction is the high pitch direction, and the widely used keyboard is a key arrangement in which the high tone and the low tone are reversed.

  When the entire right-hand keyboard 1R and left-hand keyboard 1L are viewed, the left side of the drawing (the right side as viewed from the performer) is unified as a high tone. It is similar to a keyboard such as a piano and is easy to understand for the performer.

  FIG. 2 is a diagram for explaining the depression depth of the keyboard. In the figure, three consecutive white keys are viewed from the player's direction. It is assumed that the center key among the three keys 4 is pressed as indicated by a white arrow in the figure.

  The key 4 cannot be pressed beyond a certain depth based on the keyboard structure. The depth D in the state where it is pressed down to the maximum (shown in FIG. 2) is referred to as “push-down depth”.

  The pressing depth of the right hand keyboard 1R is 10 mm, and the pressing depth of the left hand keyboard 1L is 7 mm. When performing a so-called slide performance method in which the hand (or tool) is moved on the keyboard, the hand (or tool) is moved while being pressed down to the pressing depth. The left hand 3L extending from the lower side has a bent wrist, and the keyboard is easier to play if the keyboard is depressed less than the right hand 3R extending from the upper side.

  Even in cases other than the slide playing method, the positions of the left and right hands are different. Therefore, the effect of facilitating the performance can be conceived by the fact that the left-hand keyboard 1L is not deeply depressed. It should be noted that the pressing depth is not limited to 10 mm and 7 mm, but may be that level. Further, although the white key has been described, it is preferable that the black key has the same depression depth as the white key.

  It is a shoulder keyboard that can be easily played using both hands, and can be used by many musicians.
