Abstract

The present invention relates to a device that integrates a read only memory (ROM), that is, a sound source memory and a player, in which an MP3 or various other music files are stored in an ultra-thin card shape or an ultra-small predetermined shape.

Description

Music player {Music player}

Existing music albums are LP, tape and CD. So anyone who wants to listen to music must have a player, a music player, to listen to music. In addition, in the case of MP3, it is possible to download music files through PC and transmit them to the player. There was an inconvenience of having to purchase a sound source and a player separately.

The present invention aims to provide a sound source memory and a player at the same time in an ultra-thin card shape or an ultra-small predetermined shape at a low price to a person who wants to listen to music.

Looking at the configuration by the present invention,

As shown in Figure 1

If you record the sound source (MP3 or other memory compression type sound source) data at the same time as it is manufactured in ROM (Read only memory), a very cheap one-time memory, then the memory of the sound source does not lose recording of the sound source even when the power is turned off. ,

Read only memory (ROM) 001,

A decoder 002 which decodes and plays back an MP3 or a sound source thereof;

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

As such, the control unit 003 for controlling each functional part

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

Alternatively, it is manufactured as an integrated chip by a semiconductor manufacturing method such as 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) which can insert plug (007) of earphone

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

Key switch 010 for ON / OFF, volume control, and selection function is added.

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 present 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 part is finished with a plastic card material on the front surface (011) and the rear surface (012).

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 is consistent with the surface of the main body, inserting the earphone plug (A) can be fixed to the plug as shown in the figure.

And,

When using 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 added in various forms as shown in the example of FIG.

Figure C shows the type of battery inserted from the side of the card and inserted by inserting the holder (042). In this case, a rubber bag tube can be added.

Figure D shows the type that is inserted and inserted from the front or back of the card. In the case of this type, there is a resilient material (043) of the rubber material in the form of a net or band on the back to enable a firm fixing. When the cylindrical AAA battery is pushed in from the front part, the width of the insertion hole (044) is slightly narrower than the thickness of the body of the battery (041). Therefore, it is hard to escape to the entrance again after the insertion by the elasticity of the plastic card material. Rubber material (043) 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.

In addition, since the card-type shape, various prints can be made on the front surface or the back surface 012 of the music, such as the music album Ja R.

Also,

In addition to the card type, as shown in Fig. 5, the player can be manufactured in a cylindrical or box-shaped player (052). In this shape, the battery accommodating part 053 for accommodating the battery 041 and a small and thin circuit part like the card type can be arranged in the circuit accommodating part 054 of the figure, and the audio jack insertion hole and the key switch can be arranged.

The present invention described above is possible to those skilled in the art to which the present invention belongs, various substitutions, modifications and changes can be made within the scope without departing from the spirit of the present invention and the above-described embodiments and attached It is not limited to the drawing.

Unlike conventional methods for listening to CDs, tapes or MP3 files containing sound sources, and the corresponding music player, the music data and the player are integrated, so it is convenient and does not take up as much volume or area as conventional CDs. In addition, it is easy to store and supply a large number of songs to users by creating sound source data compression technology and a large amount of ROM, if necessary.
