Description

[Detailed explanation of the idea] (b) Industrial application fields This invention is a postcard-like music box.

(B) Conventional technology Traditionally, music boxes that emit various melodies to entertain people have a drum body that is mainly rotated by a motor, and a large number of pins installed in accordance with each song, and these pins are pressed. It is played by vibrating the scale board that it touches.

(c) Problems to be solved by the invention The above music box requires at least a motor drive device and a cylindrical drum body. Therefore, it is difficult to avoid a considerable weight and volume. The present invention is a manual type, and has an ultra-thin structure that makes it card-style, making it easy to mail or carry.

(d) Method for solving the problem The pin implantation part, which is conventionally a cylindrical drum body, is made into a thin strip-shaped body 1, and the pin 2 is implanted on the surface of this plate-shaped body 1. On the other hand, a cavity 6 is provided in which the pinned strip plate 1 can be closely accommodated and passed through.

(e) Operation When the lever is pulled out using the pull hole 3, since the scale board 4 is provided facing inward at its exit, the pin 2 comes into contact with it and plays a melody. Of course, the speed of the melody is also determined by the speed at which the melody is played.

(f) Example The whole is postcard style, and the thickness is 1
It is desirable to manufacture the band to be less than a centimeter in size and weigh less than 50 grams. First, the pins 2 are implanted in the strip plate 1 according to an arbitrary curve. Next, a postcard-like thick card body 5 made of cardboard or the like
A cavity 6 is provided in the center of the plate-shaped body 1 through which the plate-shaped body 1 can pass through, and the plate-shaped body 1 with pins 2 installed therein is provided.
is inserted and accommodated. Furthermore, a scale board 4 is set at the exit in such a way as to ambush those passing by. When you hold the pull hole 3 and pull it out, the pin 2 of the strip plate 1 will come out.
The groups come into contact with the scale board 4 and emit their respective vibrating sounds, playing a melody in sequence.

(g) Effects of the invention As mentioned above, since it can be produced in the style of a postcard, the addressee and correspondence can be written on the front and back sides, and photos can be pasted on it and sent as regular mail. In particular, it can be used for a variety of purposes, including melodies for birthdays, weddings, Christmas songs, school songs, hometown folk songs, and commercial songs. That is, it is possible to select a song simply by replacing it. Furthermore, it is not limited to the size of a postcard, and it is of course possible to play a long song by configuring it to be long.

In addition, the overall configuration of this project has been made larger with a sturdy plastic case body, and the scale board has been widened to widen the range, and the pin mounting part can be attached and detached using screws 7 into groups of 8 screw holes arranged in parallel at equal intervals. You can also create your favorite songs by screwing them together. It can also be used as a teaching material for young children.
