[0066] figure 1 is a schematic diagram of the appearance of the drum-type electronic musical instrument according to the first embodiment of the present invention.

[0067] The electronic musical instrument according to the present embodiment includes a plurality of (four in the illustrated example) cushion members 10 provided on the upper casing 6 . Each upholstery member 10 has a ring-shaped light emitting unit 20 provided on its periphery. The light emitting unit 20 includes a light source 30 . As described below, in this embodiment, for example, by striking any of the cushion components 10, musical tones corresponding to the specified timbre (snare, bass drum, cymbal, etc.) of each cushion component are electronically produced, while , make the part of the light emitting unit 20 other than the light source 30 emit light. The plurality of components of the upholstery member 10 and the corresponding light emitting units 20 connected thereto are different in size, but subs...

[0100] The difference between the second embodiment and the above-mentioned first embodiment is that the structure of the light emitting unit and the way of mounting the light emitting unit to the upper housing are different. The appearance of the electronic musical instrument according to the present embodiment, the structure of the cushion part 10, the sensor support part 40, the sensor part 41, the bridge part 14, and the elastic diaphragm part 42 are all the same as those of the first embodiment, so they will not be described in detail. illustrate.

[0101] Fig. 8 is a partial sectional view of the structure of the main part of the drum-type electronic musical instrument (hereinafter referred to as "electronic drum") according to the present embodiment, which is the same as that of the first embodiment. Figure 4 same edge figure 1 Partial sectional view of line A-A.

[0113] Figure 9A is a partial cross-sectional view showing the configuration of a main part of an electronic musical instrument according to a third embodiment of the present invention. Figure 9B is a partial plan view of the fixed contact film. Figure 9A is the same as in the first embodiment Figure 4 same edge figure 1 Partial cross-sectional view of line A-A in .

[0114] In this embodiment, the vibration generated by the impact is not detected by the piezoelectric pressure sensor, but is detected by the contact switch. The structure of the light emitting unit 120, and the way in which the light emitting unit 120 is installed in the upper housing 506 are the same as in the second embodiment.

[0115] Such as Figure 9A As shown, the cushion component 310 includes a cushion skin component 311 and a backing plate 312 . The backing plate 312 is formed by forming an iron plate into a disc shape. The cushion skin member 311 is made of an elastic member such as rubber, a...

Abstract

There is provided an electronic musical instrument which enables the whole periphery of at least one pad member to shine by a simple construction, and at the same time maintain durability and low costs, and a shining method therefor. An electronic musical instrument of a drum type detects beats on a surface to be beaten of the pad member, and generates a musical tone signal in response to an output indicative of the detected beats. A light transmitter in a linear form is arranged along the periphery of the pad member and guides light which has been emitted from a light source arranged in the vicinity of one end of the light transmitter and entering the light transmitter via the one end, by utilizing principles of light propagation of an optical fiber, toward the other end of the light transmitter, and at the same time causes at least part of the light entering via the one end to emit out of the light transmitter via a light emitting surface formed by roughening part of an exposed surface of the light transmitter.

Description

technical field [0001] The present invention relates to a drum-type or keyboard-type electronic musical instrument which detects striking of a cushion member or depression of a key to generate a signal representing the detected strike and depression, thereby producing musical tones based on the signal. Background technique [0002] Generally, in electronic musical instruments that have been proposed, a part of the musical instrument is made to emit light using light emitted from a light source such as an LED. For example, Japanese Patent Publication No. 11-30983) discloses an electronic drum comprising: an optical transmission body disposed on a cushion frame forming the perimeter of each cushion; and a light source, such as an LED light source, approximately It is arranged in contact with each light-transmitting body so that the upholstery frame emits light. [0003] In addition, there is known an electronic keyboard comprising: keys made of a light-transmitting material; ...
