Conventional music albums or sound sources are LP, tape, CD and MP3. Therefore, a person who wants to listen to music must have a separate player for each sound source, that is, a music player to listen to music. In addition, in the case of MP3, it was possible to download music files through PC and transmit them to MP3 player. There was an inconvenience of having to purchase a sound source and a player separately.

An object of the present invention is to provide a sound source memory and a player simultaneously in an ultra-thin card shape at a low price to a person who wants to listen to music.

Looking at the configuration according to the present invention,

As shown in Figure 1

Simultaneously with the manufacture of ROM (Read only memory), which is a very inexpensive one-time memory, it records the sound source (MP3 or other digital compression sound source) data, and this ROM does not lose sound recording even when the power is turned off. Memory for

Read only memory (ROM) (001),

A decoder 002 which decodes and plays back MP3 or other various types of digital sound sources;

D / A converter (004) of the function to convert the data into analog music so that the user can listen to the earphone,

The control unit 003 for controlling each functional unit as described above

Each consists of a thin-film circuit module (005) or

Alternatively, the chip is manufactured as an integrated chip using a semiconductor manufacturing method such as an ASIC.

The above circuit module or integrated chip is installed on the thin film main PCB (005) or FPCB,

Here,

Power supply unit (006) that can be installed AAA type cylindrical battery

Jack insert hole (008) to insert the plug jack (007) of the earphone and

External data output terminal 009 which can transmit sound source data to an external audio device

Equipped with a key switch 010 for ON / OFF, volume control and music selection functions.

then,

The path from the recorded sound source data to the user playing the sound source to listen to the music is as shown in FIG.

In other words,

At first, when making ROM,

Sound source data in the form of digital compressed files of MP3 or other music is recorded,

The sound source data of the ROM is transmitted to the decoder and decoded.

The decoded sound source is output as analog music from the D / A converter.

The user will listen to music through the earphone.

Alternatively, the music data is transmitted to another audio device through an external data output terminal.

The above functional parts,

According to the invention,

One example is a thin card.

As shown in Fig. 1, in the center portion 005, a thin film circuit portion 005 having a memory and a player function such as the ROM 001, the decoder 002, the controller, the D / A converter 004 and the like described above is disposed. The circuit portion front surface (011) and the back surface 012 is finished with a card-like material of plastic material.

In such a card-shaped device,

A jack insertion port into which the earphone 013 can be plugged is installed in the shape as shown in FIG.

Jack insertion hole 008 has a three-part contact (033) for supporting a stereo, this contact is connected to the main circuit to transfer the analog signal of the reproduced music to the earphone plug (007). Rubber elastic material (031) (032) for fixing the plug is attached to the front card (011) and the back (012) jacket card material as shown. Therefore, normally (B) has a thickness that matches the surface of the main body has a smooth appearance, and inserting the earphone plug (A) can be fixed to the plug as shown in the figure.

And,

When connected to an external audio device, an external data output terminal 009 for transmitting data is configured. This terminal lets you deliver sound sources like you would use a CD or tape to an external audio device. Of course, there must be a separate connecting part or a new device for this.

And,

The battery that supplies power is built-in and can be equipped with a high performance dedicated battery.

However, usually AAA type cylindrical battery (041) is mainly used, and the mounting portion into which the battery can be inserted is configured in various forms as shown in the example of FIG.

Figure C shows the type of battery inserted from the side of the card to be mounted by inserting the holder (042). In this type, a rubber-elastic material is attached to the front and back of the card, respectively, and the battery is inserted therebetween. Therefore, the battery can be fixed.

Figure D shows the type of battery inserted into the front or back of the card. In this type, there is a rubber or elastic material (043) in the form of a net or band on the back to secure the battery firmly. When the cylindrical AAA battery is pushed in from the front part, the width of the insertion hole 494 is slightly narrower than the thickness of the body of the battery 041, so the flexibility of the plastic card material makes it difficult for the battery to easily come out again after the battery is inserted. The elastic material (043) of the back rubber material is to fix the battery.

And,

As shown in FIG. 1, the key switch 010 is disposed at a predetermined position on the front of the card, and typically the minimum key switch is disposed as about the ON / OFF key switch, the selection key switch, and the volume key switch of the power supply. However, more keyswitches can be placed as needed.

And, since the card-like shape, it is possible to print a variety of information on the music, such as the music album Ja R on the front (011) or the rear (012).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawing.

Unlike the conventional method of listening to a CD, tape or MP3 file containing a sound source, and a corresponding player, the music data and the player are integrated, and the price is relatively cheap. It does not occupy much space or area, and it is easy to store and supply a lot of songs to users by using sound source data compression technology or by inserting a large amount of ROM as needed.
