And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention can be illustrated by three embodiments, which will be described in detail starting from the first embodiment.

First, a first embodiment of the present invention will be described with reference to FIGS. 2 to 5. FIG.

The present invention in the first embodiment is basically composed of the moving body 10 and the rail 20. At this time, the rail 20 is provided with a removable pitch generation module 23.

The moving body 10 is provided with wheels 11a and 11b and can travel. The moving body 10 may be a toy train, a toy car, or a toy bus.

The wheels 11a and 11b provided on the moving body 10 may be provided with only the wheels 11a for traveling but may be provided with a load transmission mechanism for transmitting a load to the pitch generation module 23, A wheel 11b may be further provided.

The traveling wheel 11a is provided at two or more positions along the longitudinal direction of the moving body 10 for stable traveling of the moving body 10. [ In particular, the toy train may be provided in three or more places. Even in the case of a general automobile, the front wheel and the rear wheel are provided separately.

On the other hand, the load transmission wheel 11b is arranged on the bottom surface of the moving body 10 so that only one sound is produced in the pitch generation module 23 when the moving body 10 passes over the pitch generation module 23 to be described later. (10) in the longitudinal direction.

The rail 20 includes a bottom plate 22 and a side plate 21 which are provided at the bottom of the traveling path of the moving body 10 and guide the traveling of the moving body 10 and the bottom plate 22 and the side plates 21, And a pitch generation module 23 which is installed at a predetermined distance along the longitudinal direction to generate a sound source of a specific tone by sensing the passage of the mobile body 10. [

The rail 20 is installed mainly in the case of a toy train, but may be provided with a rail 20 to induce a toy car to run on a predetermined route.

More specifically, the rail 20 may include a lower plate 22 disposed under the moving body 10 and a side plate 21 for preventing the moving body 10 from deviating from the path.

The pitch generation modules 23 are arranged at regular intervals along the longitudinal direction of the rail 20. [ As shown in FIG. 3A, the rail 20 may be formed with an insertion groove 26 into which the pitch generation module 23 can be inserted.

In the first embodiment of the present invention, the pitch generation module 23 is a kind of a simple xylophone. Accordingly, the plurality of pitch generation modules 23 may be formed of one xylophone. However, the pitch generation module 23 is directed to the lower part, not the upper part, of the sounding plate 231 which resonates for generation of sound, unlike a general xylophone.

One pitch generation module 23 is as shown in FIG. 3B.

The pitch generation module 23 is largely composed of a sounding plate 231 and a bracket 232 for supporting the sounding plate 231.

3B, the bracket 232 is extended from the upper portion of the ringing plate 231 to a position beyond the end of the ringing plate 231, and the ringing plate 231 is suspended from the upper portion. The end of the bracket 232 is inserted into the insertion groove 26 formed in the rail 20 as shown in Figs. 4A and 4B.

The insertion groove 26 is provided with the lever 241 shown in Figs. 4A and 4B. Flexible leaf springs 24 may be provided at the upper ends of the ends of the levers 241 toward the center of the rail 20. The lever 241 is configured such that the load transmission wheel 11b under the moving body 10 pushes one end of the lever 241 under the leaf spring 24 and the leaf spring 24 as the moving body 10 passes, The projection provided at the end of the lever 241 costs the bottom surface of the sounding plate 231. [

FIGS. 4A and 4B show a process of generating sound at the sounding plate 231 in the process of passing through the mobile body 10. FIG.

At this time, a spring 244 is provided on the lower side of the movable body 10 side in the lever 241. The spring 244 acts to return the position of the lever 241 after the moving body 10 has passed. This is because the outer end of the lever 241 must be spaced apart from the ringing plate 231 of the pitch generation module 23 when the mobile body 10 is passed and the inner end of the lever 241 is urged away from the moving body 10 Because it must be positioned at the top for receipt.

The plurality of pitch generation modules 23 are inserted into a plurality of insertion grooves 26 corresponding to the plurality of pitch generation modules 23. The plurality of pitch generation modules 23 may generate the same pitch, It can also be vocalized.

In other words, the pitch generation module 23 can be detachable to the insertion groove 26, so that different music can be generated by arranging the pitch generation module 23 in a different order.

As a result, as the moving object 10 passes at a constant speed, a sound is generated for each of the pitch generation modules 23 arranged at the same interval, and a melody for maintaining a constant pitch is formed.

In particular, the pitch generation module 23 may be provided on both sides of the rail 20.

4A, 4B and 5 show that the pitch generation module 23 is provided on only one side of the rail 20, but the pitch generation module 23, as shown in FIG. 2, As shown in FIG.

The pitch generation module 23 is provided on both sides of the rail 20 so that the music of the polyphonic part can be produced.

When polyphonic music is made, monotony of monohullness can be overcome because it is possible from simple accompaniment to highly counterpoint harmony.

An example of the music that can be generated by the pitch generation module 23 provided on both sides of the rail 20 is shown in Fig.

FIG. 13 is a song called "Bure" in the suite for Bach's work number (BWV) 996 lute solo. Bree is a song made for harpsichord, a lute or keyboard instrument.

Lute can play polyphonic melody among strings, and harpsichord is also suitable for performance of polyphonic music.

As shown in FIG. 2, the music production vehicle toy according to the present invention is also provided with the pitch generation module 23 on both sides of the rail 20, so that polyphonic music can be played.

In the music shown in FIG. 13, two lines of chess pieces are simultaneously being played and the melody is played.

In this case, since the minimum note of the rhythm is an eighth note, the interval of each pitch generation module 23 can be expressed as an eighth note. In this case, the insertion groove 26- The expression of the quarter note appearing as soon as the user enters the beginning of the noun phrase is inserted into the pitch generation module of the pitch corresponding to the quarter note 23 is placed in the third insertion groove 23-6 and the pitch generation module 23 is not placed in the fourth insertion groove 26-4 that follows the rhythm of the quarter note length .

And the tempo of the tune, that is, the speed representation of the tune, can be achieved by adjusting the speed of the moving body 10. Although not shown here, the moving body 10 may be provided with a speed adjusting motor so that the speed of the tune can be adjusted.

The tone generation module 23 provided on the one side A of the rail and the tone generation module 23 provided on the other side B of the rail are used for the second expression.

Thus, a highly counterpointed expression of the music-producing vehicle toy according to the present invention becomes possible.

However, the more complicated Mars expression can not be perfectly expressed by the binary only, but becomes possible in the second and third embodiments described below.

Next, a second embodiment of the present invention will be described.

RFID technology is used in the second embodiment of the present invention.

The RFID technology is a technology for identifying an object by using a radio frequency (RF). The RFID tag 233 includes an antenna and a chip. The identification is performed by chip information recognition by the reader 101. [

In the second embodiment of the present invention, the RFID tag 233 is provided on the upper part of the pitch generation module 23, and the reader 101 is provided on the bottom surface of the moving body 10, The sound source information input to the RFID tag 233 attached to the upper part of the pitch generation module 23 is read and a pitch is generated.

The read sound source information after reading the sound source information of the RFID tag 233 is processed as digital sound source information by the middleware 103 incorporated in the mobile unit 10 and the middleware 103 transmits the processed digital sound source information to the digital- Converter (DAC) 104, and the digital-analog converter (DAC) 104 amplifies the converted analog tone signal with an amplifier (AMP) 105 to utter an audible pitch.

This process is shown in Fig. In FIG. 7, the upper large box provided with the reader 101, the power source 102, the middleware 103, the DAC 104, and the AMP 105 refers to the moving body 10 and the RFID tag 233 The lower small box indicates the pitch generation module 23.

The RFID technology will be described in more detail with reference to the present invention.

In the second embodiment, the pitch generation module 23 is provided in the form of a card or a flat box to which the RFID tag 233 is attached on the upper surface, as shown in FIG. 8B. The insertion groove 26 provided in the rail 20 is also formed into a flat shape of a box or a card according to the shape of the pitch generation module 23.

8A shows the insertion groove 26 formed on the side surface of the rail 20 according to the shape of the pitch generation module 23 of the second embodiment.

The RFID tag 233 on the upper part of the pitch generation module 23 is composed of a chip at the center and a coil enclosing the chips around the chip. The coil generates an induced current by a magnetic field emitted from a reader 101 under the mobile body 10 to be described below. The induced current activates a chip in the center of the RFID tag 233 to transmit a tone signal from the chip .

Therefore, the coil surrounding the chip of the RFID tag 233 serves as an antenna for receiving a signal emitted from the reader below the mobile body.

The RFID tag 233 includes a mutual induction method and an electromagnetic wave method. In the second embodiment of the present invention, a mutual induction method is used.

A reader 101 is provided at a lower portion of the moving body 10 to read information from the RFID tag 233 while radiating a magnetic field to the RFID tag 233. [

The reader 101 converts the information read from the RFID tag 233 into a readable digital signal and sends the read digital signal to the middleware 103 provided inside the mobile device 10. [

The middleware 103 can be defined as a software platform that collects and filters raw data and converts it into meaningful information to provide information necessary for application software and the like.

Or as a simple router that collects and delivers data.

In the present invention, the middleware 103 processes the non-operating data received from the reader 101 into a digital tone signal that can be read by a digital-to-analog converter (DAC) 104, ).

The DAC 104 also functions to convert a digital sound source signal received from the middleware 103 into an analog sound source signal.

The analog sound source signal converted by the DAC 104 is sent to an amplifier (AMP) 105 incorporated in the moving body 10 and amplified to emit a sound source signal having a human audible frequency. A known speaker may be provided on the upper side or the side surface of the mobile unit 10 in order to diverge the sound source signal.

As a result, a melody can be formed as in the first embodiment.

In the second embodiment, similarly to the first embodiment, the pitch generation module 23 can be arranged in the order in which the melody to be generated can be generated.

Particularly, in the second embodiment, it is possible to change the contents of the sound source information stored in the pitch generation module 23 without arranging such as inserting and removing the pitch generation module 23 as described above.

That is, the information embedded in the chip of the RFID tag 233 can be erased and then reentered.

Therefore, in the present invention, either the new tone generator information of the tone generation module 23 may be newly input, or the tone generation module 23 may be removed from the rails and rearranged again as in the first embodiment.

The RFID tag 233 can read the information of the RFID tag 233 in less than a hundredth of a second, unlike the conventional bar code technology. Therefore, in the present invention, There is no delay in reading the information.

Since the digital technique is used in the second embodiment of the present invention, the distinguishing feature from the first embodiment is the generation of chords.

In the score shown in Fig. 14B, the tune of the single-line rate is notated and the chord is indicated by the code progression. At this time, the pitch generation module 23 of the rail A side expresses the melody and the pitch generation module 23 of the rail side B expresses the notated chord by the code.

In the first embodiment, it is difficult to express the chord because the monaural generating module 23 on one side (A) of the rail and the pitch generating module 23 on the other side (B) can represent only the monaural rate. However, in the second embodiment of the present invention, Since the record of the sound source is read, the recorded digital sound source can represent not only the single line rate but also the complicated harmonics.

Next, a third embodiment of the present invention will be described.

The third embodiment of the present invention uses digital technology as in the second embodiment, but instead of using RFID technology in the second technique, in the third embodiment, a microprocessor (also known as Arduino technology) Is used.

The principle of the third embodiment of the present invention is conceptually represented in the configuration diagram shown in Fig.

Here, the pitch generation module 23 is configured as a signal sensing means, and reads a signal generated from the mobile body 310.

The rails 20 are provided with levers 241 whose ends protruding from the sides of the rails 20 are vertically varied due to loads transmitted from the load transmission wheels 11b,
The pitch generation module 23 is composed of a ringing plate 231 for generating a sound at the bottom of the lever 241 and generating a sound and a bracket 232 for supporting the ringing plate 231 and inserted into the side of the rail, The plurality of pitch generation modules 23 generate sound sources of the same or different pitches, and each of the pitch generation modules 23 generates a sound source having the same or different pitches, And the side plate 21, as shown in Fig.
Therefore, the passage of the moving body 10 is sensed by the signal sensing means 323 by the end of the lever 241 at the price of the sounding plate 231, and a unique signal is generated in the pitch generation module 23.

When the signal generating means 312 provided in the moving body 310 is driven by the power source to generate a signal and the signal sensing means 323 provided in the pitch generation module 23 is activated, And then sent to the adouno board 330 on which the video signal 332 is mounted. The digital cable 324 connecting the pitch generation module and the adonyno board 330 so that the sound source signal can be transmitted from the pitch generation module 23 to the adonaboard 330 can be transmitted along the length direction As shown in FIG.

The Arduino board 330 is an open source hardware platform in which a general computer is designed for general purpose, while designed for a specific purpose and capable of operating on a single chip.

A plurality of terminals are provided on the adonyno board 330 so that they can interact with various sensors and the like that can be connected to the periphery. At this time, if the circuit of the board 300 is changed to a combination of connection terminals or when the contact terminal is provided, the same effect as that of forming a new program by a computer algorithm can be obtained by adjusting the position of the contact terminal.

As in the case of the RFID technology of the second embodiment, the pitch generation module 23 inserted in each insertion groove 326 is not required to change the position of the pitch generation module 23 It is possible to generate a new song by changing the height of the pitch to be reproduced.

2, the first embodiment may have the pitch generation module 23 on both the left and right sides of the rail 320. In the RFID technology of the second embodiment or the third embodiment, It is possible to add the pitch generation module 23 to both sides of the rail 320 so as to add a polyphonic part or a chord progression to the non-monophonic part.

Meanwhile, in the third embodiment, a more complex algorithm can be performed by connecting the arduino board 330 to a separate computer via a digital cable. In addition, not only the pitches of each pitch generation module 323, Changes may also be possible. For example, the tone of the piano and the tone of the violin or pipe organ can be selected. You can also put chords in place of a single tone as well as a tone.

Particularly, if an external communication module is connected to a computer connected to the adonyno board 330 by using a LAN line or a USB port, the program is connected to a program of the computer by the surrounding smart device, It is also possible to change the pitch height and tone color of the keyboard 23.

10 and 12, the digital signal of each pitch generation module 23 received by the adonyno board 330 is changed to new digital sound source information programmed through the adonynumber 330, The digital sound source information is transmitted to the DAC 350 via the digital cable 336. [

When the DAC 350 receives the digital tone source information from the adonyno board 330 through the digital cable 336, the digital tone source information is converted into an analog tone source signal, amplified by the amplifier (AMP) 360, The music is played back. In this case, a known speaker capable of reproducing an analog signal amplified by the amplifier (AMP) 360 may be provided.

As in the case of the second embodiment, the third embodiment of the present invention configured as described above corresponds to the reproduction of the set sound source in the position of each individual pitch generation module 23, but various combinations of the respective pitch generation modules 23 are possible This is not a play but a play.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
