Description

M274614 IV. Creation Instructions π) [Technical Field to which the New Type belongs] This creation is about "portable phono player with micro hard disk", especially a portable phono player that can increase data storage and reduce production costs 0 [Prior art]

Press, portable entertainment equipment is popular, many players are racing to launch MP3 players, to achieve the convenience of "listening"; Asians love to sing karaoke 0K to bring a happy atmosphere everywhere in the festive banquet, and karaoke karaoke (KARAOK) equipment Under continuous evolution, a current vocal microphone is also quite popular; the conventional vocal microphone mainly includes a casing, which is characterized in that the surface of the casing is provided with an LCD, a key set, a connection terminal, a sound source output port, an image output port and A data input port. A central processing unit, an image signal processor, a sound codec, a communication interface, and a flash memory are arranged inside the casing.

According to the above structure, the familiar vocal microphone must use a data input port to connect to a personal computer, and the personal computer is connected to the Internet to download music data files, background image data files, and subtitle data files. These music data files, background image data files, and subtitle data files are stored in the flash memory; after the user saves the music data files, image data files, and subtitle data files in the flash memory, he / she can carry the Accompaniment microphone, and in any occasion with audio and television, connect this creation with audio and television, and the audio and television can play music melody and video subtitles to achieve the function of accompaniment

Page 5 M274614 4. Creative Instructions (2) Yes. However, the conventional accompaniment microphone uses flash memory as a storage for data files. If the flash memory with the same storage amount is compared with a micro hard disk (micr 0-hard-disk), its flash memory The price is more expensive than a micro hard disk. In addition, the flash memory data storage is much smaller than the micro hard disk. Therefore, the price of the accompaniment microphone is high, and the capacity of data files such as pictures or sounds can be limited. Only a small number of pictures can be stored, and long-term music videos cannot be stored, so users cannot sing and enjoy music, which causes considerable confusion for manufacturers and consumers.

[New content] The creator of this case has learned the lack of the above-mentioned conventional vocal microphone structure, carefully studied it, and accumulated years of personal experience in the cause, and finally designed a brand-new "portable phono player with a micro hard disk" ". The main purpose of this creation is to provide a portable record player device that can increase data storage and reduce production costs.

In order to achieve the above purpose, this creation "Portable Phonograph Player with Micro Hard Disk" mainly includes a casing, which is characterized in that: the surface of the casing is provided with an LCD, a key set and a connection terminal, and an interior of the casing is provided with a Central processing unit, image signal processor, audio codec, communication interface and micro hard disk, which can store thousands to tens of thousands of MP3 music data files, subtitle data files and background data files. The communication The interface must be connected to the Internet. Based on the above structure, the author "Portable Backing with Mini-HDD
