DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical sound data supply and reproduction system using a removable hard disk.

[0002]

2. Description of the Related Art Conventionally, in a music reproduction system, tapes, records, CDs, MDs and the like have been employed as media for storing music information. Whichever medium you take,
Insufficient memory information usually meant that users possessed multiple media, replaced media as needed, and played music.

[0003] Records and CDs do not allow the user to update the tone information stored therein. Tape, MD
Can update the musical information, but the update time of the musical sound required the same time as the performance time from the relation of the information transfer speed. Recently, there has been proposed a system in which tone compression is performed by MP3 and stored in a memory. However, at present, it is difficult to store sufficient tone information in which the price of the memory is high and satisfactory.

[0004]

The above-mentioned limitation of the conventional tone reproduction system is broken, a large amount of tone information can be handled, and the supply of the tone can be updated at a high speed to provide an inexpensive system. The purpose is to:

[0005]

According to the present invention, there is provided a hard disk for storing musical sound information and a hard disk module having a structure in which a hard disk can be inserted and withdrawn, and a structure in which the hard disk module can be inserted and withdrawn to read and decode music information. The playback module is a component.

Alternatively, a hard disk for storing musical information, a hard disk module having a structure capable of inserting and removing the hard disk, a reproducing module having a structure capable of inserting and removing the hard disk module for reading and decoding musical information, and a hard disk module. What is necessary is just to be able to comprise a tone information supply module for writing tone information to the hard disk.

A hard disk for storing musical sound information, a hard disk module having a structure to which the hard disk can be inserted and withdrawn, a reproducing function for reading and decoding the musical sound information with a structure capable of being inserted and removed from the hard disk module, and a function for writing musical information to the hard disk The tone reproduction / supply module that supplies the tone information of the above may be a component.

The reproduction module has a power supply means for supplying power to the hard disk module. Further, the reproduction module has a cache memory and caches the musical sound information of the hard disk, thereby stopping the operation of the hard disk for a predetermined time, thereby reducing the power consumption.

[0009] It is still more preferable that the reproducing module includes a memory and reproduces musical sounds in a desired order by indexing musical sound information. When the housing of the hard disk module is made of an optically transparent material, the operation of the hard disk becomes visible, and a failure or the like can be discovered beforehand.

A hard disk for storing musical sound information, a hard disk module having a structure to which the hard disk can be inserted and withdrawn, and a musical sound information supply module having a structure which can be inserted and removed with the hard disk module and for writing musical information to the hard disk. Then, it is possible to write the musical sound information on the hard disk as needed.

[0011]

According to the present invention, a large amount of musical sound information can be stored and edited at a high speed, and an inexpensive system can be realized as compared with a system using a semiconductor memory.

Reference numeral 23 denotes an audio output terminal, which can be connected to an output terminal such as a headphone 24 so that a user can hear a musical sound.

FIG. 2 is a diagram showing an example of the external appearance of the hard disk module 10 and the tone information supply module. The tone information supply module 30 includes a connector section 31 and is connected to the connector section of the hard disk module 10. In this case, the number of connectors is two, but it is sufficient to select an optimum number of connectors as necessary. If the system is for personal use, only one connector may be used. In the case of a system for supplying musical sounds for business use, a plurality of connectors may be provided and supplied at once. 32 is

Reference numeral 32 denotes a liquid crystal display unit with a touch panel, which displays an operation screen, from which the user can select and input musical tone information stored in the hard disk module. The tone information supplied here is provided in a large-capacity storage device 34 in the tone information supply module or a tone information database 36 connected via a network 35.

FIG. 3 is a block diagram showing the configuration of the system of the present invention when the hard disk module is inserted into the audio reproduction module and operates.
01 is a tone reproduction module, and 302 is a hard disk module. The hard disk 305 stores tone information as digital information, and the hard disk 305 is controlled by a CPU 306 connected via a hard disk drive 304 via a connector 303A and a connector 303B.

The digital tone information stored in the hard disk 305 is read out by the hard disk drive 304, DA converted and decoded by the audio control unit 307, amplified as audio information, and reproduced as audio from the headphone 317 via the output terminal 308. Be done

Here, the user operates the operation input unit 312 based on the index of the digital musical sound information in the hard disk.
If the order of musical tones is determined or repetitive reproduction is input, if this information is stored in the buffer memory 311 as reproduction index information, sound can be reproduced in a desired order or by repeating a desired portion. Operation input such as reproduction operation may be performed while viewing the screens of the display units of the operation input units 312 to 313.

By caching the digital tone information stored in the hard disk in the cache memory 310 as needed, the rotation of the hard disk can be stopped except at the minimum necessary time, and unnecessary power consumption can be reduced. It becomes possible to hold down. A cable 3 having a power supply control unit 314 and a plug via a built-in battery unit 316 or an adapter 315 depending on the situation.
18 to supply power.

FIG. 4 is a block diagram showing the configuration of the system of the present invention when the hard disk module is inserted into the musical tone information supply module and operates.
Connector 303A of hard disk module 302
The signal supply line is formed by joining the connector 303C of the musical sound supply module 401 with the connector 303C. CPU 402
Controls the hard disk in the hard disk module 302 through the signal supply line, and controls the tone information database 403 in the tone information supply module 401 to which the CPU belongs, or the tone information database connected via the network 404. To supply and store desired musical sound information to the hard disk module 302.

The above-described operation of supplying musical sound information is performed by an input operation on the operation input unit 406 while the operator views the screen of the display unit 407. In this embodiment, 3 in FIG.

In this embodiment, the tone reproduction module and the audio reproduction module are separate, but both modules may be integrated. If the housing material of the hard disk is made of an optically transparent hard plastic, the operation of the internal hard disk can be visually checked, and a failure can be detected in advance.

[0023]

As described above, according to the present invention, it is possible to use a hard disk, which can be accessed at a high speed and has a low unit price per bit, as a medium for storing musical sound information. As a result, it is possible to write high-speed music information on the hard disk despite its large capacity, and to easily store a large amount of music information on the hard disk at a high speed easily from a music vending machine and easily reproduce the music information. be able to.
