In this invention, the electronic rhythm musical instrument has three or more drum pads, each of which is larger than an operator for selecting a rhythm sound or a rhythm type, on the upper surface of the musical instrument body. The operability of the drum pad is improved by arranging it in the shape of a convex arc on the outside.

[Conventional technology]

As a conventional electronic rhythm instrument, an electronic rhythm sound that is a combination of tones and envelope musical tones (hereinafter referred to as “percussion instrument sounds”) similar to various preselected percussion instruments is automatically set at an arbitrarily set tempo. Alternatively, the one that is generated in synchronization with the key operation is often used.

Further, as a kind of electronic rhythm musical instrument, an electronic drum which is provided with a plurality of drum pads, detects the percussion vibration when each drum pad is struck by a stick, and electronically generates different percussion instrument sounds (mainly drum sounds) Is also offered to the market.

By using such an electronic drum, the player can obtain the same playing effect of the percussion sound as when playing the drum set by arbitrarily selecting and striking a plurality of drum pads in the stick. it can.

Conventionally, such an electronic drum is system-configured by an individual pad unit, a stand for supporting it, a stick for striking the drum pad, a sound source unit having a sound source unit and an amplifier, a speaker unit, and the like. It was

However, recently, as a simpler electronic drum, as seen in, for example, Japanese Utility Model Laid-Open No. 1-115791, a plurality of drum pads are arranged adjacent to each other with their striking portions exposed on the upper surface of the instrument body. Signal generating means for detecting the percussion vibration of each drum pad to generate a trigger signal and preferably a signal according to the intensity of the percussion, or a sound source unit for electronically generating percussion instrument sound by the signal. An integrated type with a built-in is being developed.

[Problems to be solved by the device]

However, in such a conventional electronic drum, a plurality (for example, four) of drum pads are arranged adjacent to each other in a rectangular area on the upper surface of the musical instrument main body, like the one described in the above publication. In addition, or because it is arranged in a single line or a plurality of lines in a straight line along the longitudinal direction of the instrument body, the operability of the performer at the time of playing was not so good.

In addition to the drum pad, the musical instrument body must have a space for arranging various operators such as an operator for selecting a rhythm sound or rhythm type and a sound emitting means such as a speaker. However, the operability of the instrument must be reduced, and the downsizing of the instrument reduces the stability of the instrument itself during performance.

The present invention has been made in view of such conventional problems, and improves the operability of a group of drum pads in an electronic drum or an electronic rhythm musical instrument having the electronic drum, and does not make the drum pads too small even if the size is reduced. The purpose is to secure a sufficient space for arranging the operators and sound emitting means and to improve the stability of the instrument body.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention, in the electronic rhythm instrument as described above, exposes at least three drum pads on the upper surface of the instrument body, each drum pad being larger than an operator for selecting a rhythm sound or a rhythm type. Then, as a whole from the player's side, they are arranged in an arc shape protruding outward.

Further, various operators including an operator for selecting a rhythm sound or a rhythm type are arranged in a concave portion inside when viewed from the player side with respect to a portion where the drum pad of the musical instrument body is arranged in an arc shape.

Further, it is desirable that the sound emitting means is provided on a convex portion outside the drum pad of the musical instrument body as viewed from the player side with respect to the circular arc shaped portion.

[Action]

With the above-mentioned configuration, 3
Since all or more drum pads are arranged in a substantially equal distance relationship, the operability is extremely improved.

Further, since various operators are arranged in the remaining portions of the concave portion formed inside the portion where the drum pad of the instrument body is arranged in an arc shape, the space of the instrument body can be effectively used.

Further, if the sound emitting means is provided on the convex portion provided outside the portion where the drum pad of the musical instrument body is arranged in an arc shape, the instrument body as a whole exhibits an inverted Y-shape, which improves stability. Even if you hit the drum pad, it will not rattle.

It is also possible to reduce the size of the musical instrument body and save the material of the exterior housing while ensuring a sufficient space for arranging each part.
