As shown in FIG. 2, the function operation unit 2 includes a play / stop key 21 for playing and stopping, a fast forward key 22, a fast backward key 23, and a scroll up key 24 for searching for a music piece. And a scroll down key 25, a volume key 26, a menu key 27, a mute key 28, and the like.

Reference numeral 3 reads and processes the digital audio signal stored in the data storage unit 1 according to the type given by the user's operation of the function control unit 2, outputs the signal to the sound source control unit 7, and simultaneously downloads the digital audio signal. The digital signal processing unit 3, which operates to perform loading and reproducing and fast forward and backward operations, is shown.

In addition, the digital signal processor 3 reads the advertisement video information stored in the data storage unit 1 at predetermined time intervals during the reproducing operation, and transmits the advertisement image information to the CPU 12 of the game machine through the interface unit 6 to play the game machine. Through the display unit 13 of the advertisement image is output for a predetermined time.

That is, the overall operation of the pack for reproduction is controlled by the signal processing operation of the digital signal processing unit 3, and the digital signal processing unit 3 operates according to an operation program stored in the program memory 4.

Reference numeral 5 denotes a communication unit 5 that communicates data with a PC. The communication unit 5 includes a communication port 51 formed on one side of the case 10 as shown in FIG. It is connected to the USB port of the PC through the communication port 51 has a function of receiving a digital audio signal downloaded from the PC and storing it in the data storage unit (1).

Reference numeral 6 denotes an interface unit, which is connected to the connection port 11 of the game machine via a connection port 61 formed at one end of the case 10, and is the title of a playback song supplied from the digital signal processing unit 3; Or graphic data, such as lyrics data or album jacket, is supplied to the CPU 12 of the game machine so that the song title, lyrics, album jacket, and advertisement video of the playback song can be output on the display unit 13 of the game machine. In addition, by supplying the power supplied from the game machine through the connection port 11 to each component of the play pack to enable the play pack to operate normally.

Reference numeral 7 denotes a sound source control unit 7 for converting the digital audio signal output from the digital signal processing unit 3 into an analog signal while reproducing the original music signal during the reproduction operation, and the music signal output from the sound source control unit 7. After amplified by the amplifier 71 is supplied to the first jack 8 formed on one side of the case (10).

The first jack 8 is formed on one side of the case 10, so that the user can connect the earphone jack to the first jack 8 so that the user can listen to the digital audio played in the pack for playback through the earphone. Will be.

In addition, another second jack 9 is formed at one side of the case 10, and the second jack 9 is for connecting a microphone jack, and a user can connect a jack of a microphone to the second jack 9. The user's upbringing input through the microphone is recorded in the data storage 1.

Referring to the operation of the present invention configured as described above is as follows.

First, the user has a game machine and a pack for playing, which game machine is used to enjoy the game in need.

When the connection port 61 formed at one end of the prepared pack case 10 is connected to the connection port 11 of the game machine, the power of the game machine is interfaced via the connection port 11 and the connection port 61. 6), the interface 6 supplies the input power to each component of the pack.

When the pack for playback is connected to the connection port 11 of the game machine as described above, the digital signal processor 3 transmits the title information of several pieces of music stored in the data storage unit 1 via the interface 6 to the CPU of the game machine. (12), the CPU 12 outputs the input title information to the display unit 13 as shown in Figure 4 so that the user can see the title of the stored multiple songs, the user at this time The title can be retrieved by operating the scroll up key 24 and the scroll down key 25 to be configured.

When the user selects one of the titles displayed on the display unit 13 and inputs the play / stop key 21, the digital signal processing unit 3 reads the digital audio signal for the selected song from the data storage unit 1. And at the same time, the lyrics data for the selected song and the graphic information about the album jacket are read and transmitted to the CPU 12 of the game machine through the interface unit 6, and the sound source control unit 7 is inputted. The digital audio signal is restored to the original music signal and simultaneously converted into an analog signal and supplied to the first jack 8 through the amplifier 71.

The user can connect the earphone jack to the first jack 8 so that the user can listen to the digital audio played by the sound source control unit 7 through the earphone, and the currently playing song through the display unit 13 of the game machine. As lyrics and album jacket videos are output, users can access various information about the song during playback.

When the digital audio signal is reproduced as described above, the digital signal processing unit 3 reads the advertisement image information stored in the data storage unit 1 at predetermined time intervals, and reads the CPU 12 of the game machine through the interface unit 6. ), And the CPU 12 graphically processes the input advertisement image and outputs the image to the display unit 13 so that the user can view the advertisement image output on the display unit 13 in the middle.

On the other hand, the user can connect the microphone to the second jack (9) in the process of singing a song while singing along with the song can be recorded.

That is, when the user sings, the voice input through the microphone is converted into a digital signal through the amplifier 71 and the voice controller 7 and stored in the data storage 1.

As described above, the present invention includes a pack that is connected to a portable game machine, which is distributed in a large quantity, and stores several digital audio signals, lyrics, and graphic data such as lyrics and album jackets in the pack. By configuring the recording means, the means for reading the digital audio signal and restoring the original music signal, the interface unit for supplying the power supplied from the game machine to the drive power of each component inside the pack, and so on, You can listen to digital music such as MP3 by listening to it, and download new digital audio signal from PC so that you can save and listen to new music at any time. It is possible to output the graphic screen such as through the display unit of the game machine. The output coming through the display of the advertisement video game machine in favor reproduction can be expected an effect to provide a pack for the digital audio reproduction so as to obtain the advertisement effect.
