Description

[Detailed explanation of the invention] (Field of industrial application) This invention is a desk mat with a keyboard attached to it, allowing school children in ordinary households to practice music easily and happily while sitting at their desks. This invention relates to a desk mat with a touch switch keyboard instrument.

(Conventional technology) Traditionally, when schoolchildren and others practiced musical instruments, they used the piano,
It is common to use an organ etc. for pitch education. Therefore, there is a drawback that it is not possible to practice easily and enjoy music in a place without a piano, organ, etc.

In addition, in recent years, sheet-shaped keyboard instruments such as Tatsuchi-switch, which are thin and bendable, have been seen here and there, but these belong to toys and entertainment, and it is a hassle to purchase each as a sheet-shaped keyboard instrument. It has many disadvantages, requires space for use, and is troublesome as it requires cleaning up every day.

(Problems to be solved by the invention) Among the problems mentioned in the conventional technology, in the former case, it is difficult for kindergarteners and lower grade practitioners to practice music easily and regularly using pianos and organs. There is a problem. In addition, the latter sheet-shaped keyboard instrument has the problem that it is very troublesome to use it each time, making it difficult to easily practice pitch or have fun with the keyboard instrument.

Therefore, this idea was made in view of these conventional problems, and its purpose is to attach serial numbers of musical instruments and speakers to desk mats that are always placed on the top of school children's desks. To provide a desk mat with a tactile switch serial number musical instrument, which allows a practitioner such as a school child to freely and easily practice pitch sense as needed even when sitting at a desk by embedding a section.

(Means for Solving the Problems) In order to achieve the above object, the desk mat in this invention is made of a hard plastic substrate 4.
and a transparent soft plastic top plate 5, with a keyboard 6 interposed therebetween, and the substrate 4 is formed of two layers, an upper substrate 3 and a lower substrate 2. The upper substrate 3 is provided with fitting recesses 10 into which keyboards 6 of various shapes are fitted and fitting parts 11 into which the speaker section 8 is fitted, at predetermined positions. The upper surfaces of the upper substrate 3 are substantially flat with the plane of the upper substrate 3.

(Function) This invention has a structure as shown in the upper surface, and to explain how to use it now, the desk mat 1 shown in FIG. 2 is placed on the top plate of the desk 16 shown in FIG. 1.
When writing in this state, use the surface of the desk mat 1 other than where the keyboard 6 is located, and
For example, when a learner practices a musical instrument with a keyboard 6, by pressing the keyboard 6 from the top of the transparent soft plastic top plate 5, the sound from the speaker 8 is emitted from the gap, making it easy to practice music. It is extremely useful for educational purposes and for educational purposes.

(Embodiment) An embodiment of this invention will be described with reference to the drawings. In FIG. 2, a desk mat 1 is made up of a transparent soft plastic plate 5 with a rectangular surface and a relatively hard plastic substrate 4. , a keyboard 6 interposed between the soft plastic plate 5 and the substrate 4.
It is composed of

The substrate 4 is formed of two layers: an upper substrate 3 at the top and a lower substrate 2 at the bottom. The upper substrate 3 has a fitting recess 10 of a predetermined shape in which the keyboard 6 is housed, for example, at the lower end portion on the right side.
Furthermore, a fitting part 11 is provided at a predetermined position above the upper substrate 3, in which, for example, a thin battery part 7, a speaker part 8, an I/C part 9, etc. are housed. 12
6 shows an extremely thin conductive wire connected to the keyboard 6 and the thin speaker section 8, etc., and what is shown in FIG. is an insulator and its insulator 13,
Contact part 14 with a conductor or conductors printed on the top and bottom of 13
A contact portion 15 is provided and formed in a sandwich-like shape, and the contact portion 14 and the contact portion 15 are in contact with each other. Reference numeral 16 indicates a desk for school children, etc.
17 is a plastic top plate 5 of the desk mat 1;
This figure shows a welded wire that connects the board 4 and the board 4 at their upper edges so as to be openable and closable.

(Effects of the invention) Since this invention is configured as described above, it produces the effects described below. In other words, this desk mat with a keyboard instrument has the extremely excellent effect that school children can use it for learning writing tasks in the same way as conventional desk mats, and can also practice music while learning musical notation symbols. Using a desk mat also has the effect of serving two purposes: one for writing and one for music learning. The board is formed into two layers, an upper board and a lower board, to increase the overall strength, and a fitting recess in which the keyboard is housed is provided at the lower end of the upper board, and a battery part and an I - By forming the fitting parts in which the C part and the speaker part are housed, the keyboard part, the battery part, the I/C part and the speaker part are each stably fitted, and movement and separation are prevented. In addition, the upper surface of the keyboard, battery section, I/C section, and speaker section can be formed flat on the surface of the upper substrate, which has the practical effect of not getting in the way during writing work.
