Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a music playback device that can select and display any song, and can be used in the general field of music playback devices to play music tapes using magnetic recording and playback technology. Equipment such as tape recorders, karaoke, BGM, commercial
It replaces machines, modern laser recording/playback devices, and traditional record players.

It can also be used in electronic musical instruments as a selective reproduction device for rhythm patterns, chord patterns, bass running patterns, etc.

The structure of the conventional example and its problems The structure of the magnetic recording and playback device is well known, so it will be omitted here, but the problem is that the music tape deteriorates with the number of times it is used, and not only does the sound quality deteriorate, but also the common name In some cases, an unpleasant physical sound called tape squeal was generated.

In terms of sound quality, it is said that the limit is 100 to 200 times at most, and anything more than that is considered unbearable for those who care about sound quality.

Additionally, a mechanism was required to drive the tape, and as the mechanism deteriorated, the sound quality deteriorated due to an increase in wow and flutter.

There are also limits to miniaturization in terms of size and weight, and although microcassettes have appeared, they have not become widely popular due to sound quality, durability, and other reasons. While products made only of electronic components are being miniaturized, it has been difficult to miniaturize products because they include tape cassettes and drive mechanisms.

Further, the number of songs that can be stored on one tape is usually 4 to 8 songs in the case of a cartridge, and 8 to 12 songs in the case of a cassette. Therefore, when carrying tape cassettes or cartridges with more than 50 songs, they had to be carried in the trunk, which was quite cumbersome.

Also, with tape, random access was extremely difficult, and it took a long time to find the beginning of the selected song.

Even in players using record discs, the deterioration in sound quality is even worse than in the case of tapes, with experts saying
It is said that 0 plays is the limit for pure music.
It is also inconvenient to carry, and players are larger than telecom players, so portable ones are almost gone these days. The number of songs that can be accommodated is 4 to 8 songs per record. It also had drawbacks such as deformation and cracking when exposed to sunlight or when objects were placed on it.

Even with the electronic keyboard of an electronic musical instrument, it is necessary to memorize magnetic cards and barcode sheets one by one, and it is necessary to memorize one song at a time, and it is not possible to store two or more songs at the same time.

Also, there is no device to display the song title, song number, cassette, cartridge, record number, etc.

Furthermore, there are no devices that change the color of the display to match the content of the song, such as the name or number of the song.

Purpose of the Invention The present invention provides analog/analog music waveforms such as melodies and accompaniments.
By digitally converting it, adding a code code, and storing it in a read-only memory (ROM) as song code data in advance, and then loading this ROM into a music playback device and playing it back, it is possible to use a conventional magnetic recording/playback device or record player. To provide a music playback device that is small, lightweight, and inexpensive compared to other devices, allows for instantaneous song selection or programmatic song selection, displays the name of a selected song, and displays almost no change in sound quality no matter how many times it is used, as well as displays the content of the selected song. The purpose of this is to display the song title and song number.

In addition, when applied to electronic musical instruments, by selecting and installing a ROM that stores the desired melody, accompaniment, sound effects, etc., you can eliminate the hassle of memorizing each song.
The purpose of this system is to enable programmed music selection and continuous reservation playback, with the names and numbers of the songs being displayed one after the other.

Structure of the Invention In order to achieve the above object, the present invention utilizes a central processing unit (central processing unit) controlled by a von Neumann stored program.
A control section consisting of a CPU), a read-only memory (ROM) in which the above program is stored, and a memory (RAM) that has a working area for the above program and can be stored and read, and can be decoded and executed by the above control section. a song code data storage cartridge section comprising a read-only memory cartridge (ROM cartridge) in which code data for melody parts and accompaniment parts of a plurality of songs are stored in advance; and the song code data processed by the control section. A part of the music synthesizer constituted by a music synthesizer circuit that converts the song code data in the storage cartridge section into mechanical sound vibrations and generates music, and selects arbitrary song code data stored in the song code data storage cartridge section. an operation section that instructs and stores the above control section to It is composed of a display section that displays the song title and song number.

In addition, the cartridge number is stored in the song code data storage cartridge, and it is configured to be removable, so that many songs can be selected by replacing the song code data storage cartridge with the song code data storage cartridge containing different song data. It also displays the song code data storage cartridge number.

Further, the cartridge number is stored in the song code data storage cartridge part, and a plurality of cartridges are installed, so that a large number of arbitrary songs can be selected without replacing them, and at the same time, the number of the cartridge being selected is displayed.

Further, the music code data storage cartridge number, the selected music title, and the music number are displayed in color in correspondence with the content of the music.

If one song is specified, the playback ends after one song, and if multiple songs or the number of repetitions are specified, the playback is performed until all of the specified songs or all of the specified number of times are played based on the specification. Unless there are additional specifications, playback ends when the specified playback ends.

When the specified song is selected and a signal is sent to the ROM 20υ, a song name signal is also sent to the cache generator (7), so the song name is displayed on the internal bus l! 5σ to the display section (8
) is displayed. If the song number is stored in the ROM2C3υ, the song number is also displayed on the display section (8) in the same way. The classification number of the song code data storage cartridge section (3) is also displayed in the same manner.

The flow of these operations is as shown in FIG.

If you connect expansion ROM a el), ROM 3 (
Similarly, the melody and accompaniment stored in ROM B (6σ) are read out and played back from ROM B (6σ).

The music synthesizer part (4) is similar to that used in electronic musical instruments, and the control section (2) is similar to that used in computers. The operation part (1) is similar to the keyboard used in computers, etc., and the key part used in calculators, etc., and the display part (8) is the same as the keyboard used in computers, etc., and the display part (8) is used for purposes such as liquid crystal display, display tube, EL, etc. You can choose it arbitrarily depending on how you use it.

Song selection and additional functions can also be specified by pressing keys with song titles and functions written on them using number designations, combinations of numbers, multi-item key mats, and the like.

As shown in FIG. 4, a method for storing music code data in the ROMs 2 and 3 for storing music code data is to store pitches, lengths, chords, etc. in one block of 8 bits.

You can use a ROM writer to memorize one block at a time in ROM 2 and 3, but an effective method is to digitize the melody and accompaniment using a music waveform analyzer, and then automatically store it in the ROM using a ROM writer. be.

Alternatively, the melody and accompaniment may be read and stored from a digitally coded magnetic recording type play card or a bar code printed type play card.

The composition of the music is as follows.

Fig. 5 shows an example of a specific product of the present invention.The surface of the device includes an operation part (1), a song title display part f8η, a display part (8) such as a ROM cartridge number display part, and a speaker (materials). ), a ROM cartridge mounting section, etc. are attached, and a control section (2), part of a music synthesizer (4), a character generator section (7), etc. are built into the main body (5).

Effects of the Invention The present invention has the following effects compared to the conventional music tape type and record disk type.

(1) Multiple songs can be recorded.

A 256 kilobit (82 kilobyte) ROM can store 100 to 800 songs, and a 1 megabit ROM
300 to 1000 songs can be recorded on one unit.

Therefore, in most cases, one ROM is sufficient in practice.

(2) You can instantly find the beginning of 6 songs.

Since it is digitally recorded and there are no mechanically moving elements for song selection, you can instantly find the beginning of a song. There are no mechanical movement elements such as moving the tape or moving the pick knob (No. 3), you can stop midway and move to the next song in an instant.

(4) You can make a reservation.

You can select and program the playback of the same song repeatedly or continuous playback of different songs.

(5) The pitch does not change even if the speed is changed.

Unlike tape and record systems, where the output is affected by the speed, the speed and pitch are recorded in the ROM as each code data, so the pitch does not change even if the speed is changed.(6) , there is no deterioration in sound quality.

Since there are no rotating or sliding mechanical parts, there is no wear on the tape or head, there is no wear on the record or the pick knob needle, and the sound quality does not deteriorate no matter how many times it is used. - (7) No abnormal noise occurs.

In the case of tapes, an abnormal sound called tape squeal occurs as the number of times they are used increases, and in the case of records, there are problems such as increased scratching noises, but the products of the present invention have no parts that wear out or deteriorate, so they can be used easily. No abnormal noise is generated even if the number of times is increased.

(s), The price per i song is low.

Comparing the conventional method of cassette tape, which is said to be cheaper per song, with the ROM method of the present invention, detailed calculations are omitted, but it is said that the ROM of 256 kilobits.
In this case, it will be 1/8 to 1/4 of the cassette tape type.

(9) Significant miniaturization is possible.

Comparing the dimensions of a cassette tape and the ROM of the present invention in the case of recording 100 songs, the cassette tape's dimensions are 27.
It becomes 1/0.

00, it can be made very light.

In the case of recording 100 songs, the device of the present invention is 1/34th lighter than a cassette tape.

0]), it becomes possible to easily select different types of music by exchanging the ROM, and it is possible to switch to a music genre that suits the individual's taste. For example, you can choose the music of each genre, such as chants, military songs, folk songs, enka, popular songs, jazz, chanson, etc., depending on your taste.

One ROM can store 100 to 300 songs, so if you have one of each genre, you can match most people's tastes.

(b) By installing multiple ROMs containing different types of music, it will not be difficult for people with different tastes to select songs when a large number of people are having a party.

Alpha version The song title is displayed, so you can see the relationship between the melody and the song title. This is especially useful for beginners, who may hear the melody but not know the name of the song.

The title of the song is displayed each time the α→0 song changes, so you can see which song is being played, and even if there is an unknown song among the programmed songs, you can predict the next song. This is especially useful in situations such as karaoke, as you can see when it will be your turn.

Q! li1. Since the ROM cartridge number is displayed, there is no need to open the lid of the mounting section to check which ROM is installed.

As described above, the present invention is a progressive technological creation that can provide the world with a novel and highly effective product.
