The musical instrument handled by the present invention is a musical instrument that vibrates the vibrating membrane 20 on the upper surface of the body 10 to produce a sound. For example, shamisen, sanshin, kokyu, banjo, gottan, guitar, ukulele, drum, etc. are applicable.
The vibrating membrane in the present invention refers to a skin or a back skin in the shamisen or kokyu, and is an expression including a thin vibrating plate used in a Gottan or a guitar, and the meaning of the film is widely interpreted.

The musical instrument of the present invention has a mechanism in which a light source unit 30 is provided inside the body 10 and the light projected from the light source unit 30 illuminates the vibrating membrane 20 to produce a visual effect.
Furthermore, by providing a translucent adjustment member that adjusts the amount of light projected to the outside, it is possible to adjust the amount of light and enhance the effect.

FIG. 1 is a perspective view showing a state before a light transmission adjusting member is attached to the body 10 of the musical instrument 100, and FIG. 2 is a schematic view showing an internal structure and the like of the body 10. The drawing is centered on the body 10, and a part of the peripheral portion is omitted.
As shown in the figure, a light source unit 30, a power-related member group, and a light transmission adjusting member are attached to a musical instrument (shamisen) having a basic configuration such as a body 10, a vibrating membrane 20, a rod 40, a middle tree 41, a piece 45, and a thread 80. The instrument 100 is equipped with such items.
Further, the vibrating membrane 20 is stretched on the upper surface of the body 10 and is in a fixed state.

The light source unit 30 is configured by a member having one or a plurality of light emitting units 31. As the light source, an LED, a fluorescent lamp, an organic EL, an incandescent lamp, a laser, or the like can be considered, but an example using an easily available LED is shown.
In the case of an LED, since the light emitting section 31 is a point light source, it can be arranged in a line.

The power-related member group includes a battery 90, a DC cable 91, a connecting member 92, an AC adapter 93, a switch 94, a light source controller 95, and the like. In addition to the method of inserting the AC adapter 93 into a power outlet to supply electric power to the light source unit 30, it is possible to enhance mobility and portability by using the battery 90 inside the body 10.
It can also be used as a night light by adjusting the amount of light from the light source to make it dim. Furthermore, by providing a battery for power failure, it can be used as an emergency light. The switch 94 can switch ON / OFF of electric power. The light source control unit 95 has a circuit for controlling the amount of light and the change of the light color according to a program, and can enhance the design and production.

The light transmission adjusting member is a member that is a superordinate concept of the plate member 50, the sheet member 60, and the reflecting member 70, and is a member that can adjust the amount of light projected from the light source unit 30.
As shown in the figure, the plate member 50 (an example of a translucency adjusting member) is a thin plate and is made of a translucent material (for example, an acrylic plate or a glass plate). By providing the plate member 50 with irregularities, it is possible to change the undulation due to the difference in translucency. In addition, it is possible to enhance the designability and performance by changing the highly translucent portion and the low translucent portion in a gradation pattern.

Further, the plate-shaped member 50 is provided with a processed portion 51. The processing section 51 is subjected to cutting processing such as facets and blurring processing such as frosted glass. The processed portion 51 can diffuse light passing through the plate member 50 or weaken the amount of light passing through the plate member 50.

The sheet-like member 60 (another example of the light transmission adjusting member) described later is a substantially flat and thin member, and can be attached to the back side of the vibrating membrane 20. By giving various patterns to the sheet-shaped member 60, it is possible to produce a lighting effect. In addition, it is also possible to attach a seal of letters or patterns on the back side of the vibrating membrane 20.

A thread hole 14 is formed on the side surface 11 of the body 10, and the thread 80 appears from the inside of the body 10 to the outside through the thread hole 14. Although the shape of the musical instrument 100 shown in the figure has peculiarities as a shamisen, the present invention is not limited to the shape of this musical instrument.
The plate member 50 can be placed between the thread 80 and the vibrating membrane 20. The plate-like member 50 can be held downward by utilizing the force of the thread 80 pressing downward, and the plate-like member 50 can be stably arranged.

FIG. 3 is a schematic diagram showing an internal structure of the body 10 of the musical instrument 100A.
Inside the body 10 of the musical instrument 100A, a reflecting member 70 (another example of a light transmission adjusting member) is provided. The surface of the reflecting member has a surface that appropriately reflects light. The reflecting member 70 is wound around the outer periphery of the middle tree 41, and the rotating force is transmitted from the electric motor 96 via the rotating belt 97. Then, the reflecting member 70 rotates so as to slide on the outer periphery of the middle tree 41.
As the reflecting member 70 rotates, the light emitted from the light source unit 30 is diffused inside the body 10. During the rotation, the light emitted from the light source unit 30 continues to change variously through the reflecting member 70. By doing so, the designability and performance of the musical instrument 100A can be further enhanced.

Although not shown, it is possible to provide a mechanism in which the reflection member 70 is attached near the tip of the vibration-assisting tool having the shape of an elastic rod and the vibration-assisting tool is fixed inside the body 10. The shape of the reflection member 70 may be a substantially spherical shape like a mirror ball or may be a thin plate shape. It is also possible to provide a mechanism in which the potential energy of the reflection member 70 changes due to the movement of the player, etc., and the reflection member 70 moves vertically and horizontally. The movement of the reflection member 70 can enhance the effect of the light emitted by the light source unit 30. The number of the reflecting members 70 may be one or more, but if a plurality of reflecting members 70 are attached, the designability and performance can be further enhanced.

FIG. 4 is a schematic diagram showing an internal structure of the body 10 of the musical instrument 100B.
The conventional shamisen is assumed here. A chord 85 is attached to a tip 42 of the midtree 41, which is a protruding portion, and a thread 80 is tied to a tip portion 86 of the chord 85. The present invention can be applied to the shamisen having the chord 85.

FIG. 5 is a perspective view showing an example of the sheet-shaped member 60.
As shown in the drawing, a character 61 having a message property is drawn on the surface of the sheet member 60. The sheet member 60 can be attached to the back surface of the vibrating membrane 20.
When the light is off, the characters that could not be seen are highlighted when turned on, which makes it possible to create a shadow effect.
For example, when used as an interior in a hotel or the like, a message for customers can be transmitted.

FIG. 6 is a perspective view showing another example of the sheet-shaped member 60. As shown, the sheet-like member 60 is provided with a through hole 62. The through hole 62 can also be formed by treating the sheet member 60 like a paper pattern and cutting it out. Further, instead of the through hole, a material having high light transmittance may be attached to this portion. By using the sheet-shaped member 60, it is possible to expand the area that can be rendered by the light source.

7 is a schematic diagram showing the internal structure of the body 10 of the musical instrument 100C, FIG. 8 is a plan view when the light is off, and FIG. 9 is a plan view when the light is on.
As shown in the figure, a musical instrument (taiko) having a basic configuration such as the body 10 and the vibrating membrane 20 to which the light source unit 30, the power-related member group, the light transmission adjusting member, and the like are attached is the musical instrument 100C. A light source unit 30 is attached inside the body 10.
In the example shown in the figure, the characters "matsuri" that were not visible when the lights were turned off are now visible when the lights are on, and you can enjoy the change. The area that can be rendered by the light source can be expanded in various ways.

The vibrating membrane 20 does not need to be in a white or plain state, and the present invention can be applied even when a pattern, color, or character is drawn on the surface of the vibrating membrane 20.
Since the vibrating film 20 itself is embossed and the concavo-convex is formed on the front surface or the back surface of the vibrating film 20, it is possible to change when the design is turned on, which is invisible.
By drawing on the front surface or the back surface of the vibrating film 20 using a plurality of dyes having different degrees of light transmission, it is possible to enhance the effect of the light emitted by the light source unit 30.

Although not shown, a plurality of translucency adjusting members can be replaced and used by providing an opening on the side surface 11 of the body 10 in which a translucent adjusting member can be inserted and removed freely. It is also possible to use a plurality of light transmission adjusting members at the same time.
When the plate-shaped member 50, the sheet-shaped member 60, and the reflection member 70 are combined in a complex manner, the effect of production can be further enhanced.

When a design such as a pattern, color, or character is drawn on the back surface of the vibrating membrane 20 with a white dye, the design becomes difficult to see when the light is turned off. Then, the change between when the light is turned off and when the light is turned on is further increased, and it is possible to improve the design and the performance.
If the pattern, color, characters, etc. are drawn on the back surface or the front surface of the vibrating membrane 20 in substantially the same color as the color tone of the front surface of the vibrating membrane 20, the same effect as described above can be obtained.
The same effect can also be obtained when a thin paper of the same color as the surface of the vibrating membrane 20 is attached to the back side of the vibrating membrane 20.
