Description
[technical field]
The utility model relates to player, relates in particular to a kind of digital audio-frequency player.
[background technology]
At present, other player of most of HIFI (High-Fidelity, high-fidelity) level all is the combination of CD player or floppy disk, and it reads complicated in mechanical structure, the cost height.The high speed development of internet brings unprecedented opportunities for the audiophile, and a large amount of high-quality lossless audio forms such as WAV, WMA, audio resources such as APE, FLAC are extremely easy to obtain on network.Yet, these high-quality audio resources must imprinting become CD could be on the CD player normal play, and audio quality can descend to some extent after imprinting became CD usually, and imprinting needs corresponding cost, technical tool and trifling operating process.
[utility model content]
Based on this, be necessary to provide a kind of not only convenient light and handy, save cost but also the digital audio-frequency player of HD Audio playing function can be provided.
A kind of digital audio-frequency player comprises:
Be used for connecting the storage device interface module of memory device;
With described storage device interface module is electrically connected audio file is decoded and supported the integrated circuit control module of APE lossless audio file layout decoding;
The DAB output interface module that is used for the DAB behind the output decoder that is electrically connected with described integrated circuit control module; With
Each module that is used to that is electrically connected with described storage device interface module, integrated circuit control module and DAB output interface module provides the power module of work required voltage respectively.
Preferably, described storage device interface module is one or more in USB interface, SD interface, MMC interface, SATA interface, MircroSD interface, the MiniSD interface.
Preferably, also comprise the wireless communication module that is used for receiving remote signal that is electrically connected with described integrated circuit control module.
Preferably, described wireless communication module is infrared communication module or 2.4G wireless communication module or WiFi communication module.
Preferably, also comprise the load module that is used for user's input control signal that is electrically connected with described integrated circuit control module.
Preferably, described load module is button or touch-screen.
Preferably, also comprise the display module that is used to the information of displaying the play that is electrically connected with described integrated circuit control module, described display module is any one in LCD display, light-emitting diode display, the CRT monitor.
Preferably, also comprise the memory module that is used for storing audio files that is electrically connected with described integrated circuit control module.
Preferably, described memory module is a flash memory.
Preferably, described DAB output interface module is optical fiber output interface and/or coaxial output interface.
Above-mentioned digital audio-frequency player, make digital audio-frequency player connect multiple memory device by the storage device interface module, can obtain the various good quality audio of multiple memory device, stores, by the integrated circuit control module of supporting the decoding of the APE lossless audio file layout various audio files of decoding, outputting digital audio, need not to become CD on CD Player, to play the audio resource imprinting, and because the APE audio file is very little, can not take the more storage space of digital audio-frequency player, so the digital audio-frequency player that the utility model provides is both convenient light and handy, save cost, can provide the HD Audio playing function again.

[embodiment]
Embodiment one
As shown in Figure 1, digital audio-frequency player 100 comprises integrated circuit control module 102, storage device interface module 104, DAB output interface module 106 and power module 108, wherein:
Integrated circuit control module 102 is electrically connected with storage device interface module 104, output interface module 106 and power module 108 respectively, is used for audio file is decoded.
Integrated circuit control module 102 is supported the decoding of APE (a kind of digital music file form) lossless audio file layout, and when playing the APE audio file, support CUE (cuesheet, Disc image secondary file or tab file), divide the rail file to handle CUE, make display interface seem more directly perceived as a music file.Because the APE file size has only CD half, so digital audio-frequency player 100 can be saved a large amount of storage resources.
Storage device interface module 104 is used for connecting memory device.Storage device interface module 104 can be USB interface, SD (Secure Digital Memory Card, safe digital card) interface, MMC (MultiMediaCard, multimedia storage card) interface, SATA interface (Serial Advanced Technology Attachment, Serial Advanced Technology Attachment, a kind of serial hardware driver interface), one or more in MircroSD interface, the MiniSD interface based on industry standard.Make digital audio-frequency player 100 can connect multiple memory device by these interfaces, these memory devices can be USB flash disk, SD card, mmc card etc., make that the capacity of digital audio-frequency player 100 is unrestricted.
Digital audio-frequency player 100 obtains the audio file of the various forms of storing in the memory device by storage device interface module 104, and integrated circuit control module 102 is decoded to these audio files.Among this embodiment, integrated circuit control module 102 is also supported WAV, WMA (Windows Media Audio), FLAC (Free Lossless Audio Codec, the lossless audio compressed encoding), one or more the decoding of audio file formats of AAC (Advaced Audio Coding, Advanced Audio Coding), MP3, MPEG etc.
DAB output interface module 106 is used for the DAB behind the output decoder.DAB output interface module 106 can be optical fiber output interface and/or coaxial output interface.
Embodiment two
As shown in Figure 2, digital audio-frequency player 200 comprises integrated circuit control module 202, storage device interface module 204, DAB output interface module 206, wireless communication module 208, load module 210, memory module 212, display module 214 and power module 216.Wherein integrated circuit control module 202 is identical with integrated circuit control module 102 among the embodiment one, storage device interface does not have module 204 identical with storage device interface module 104 among the embodiment one, DAB output interface module 206 is identical with DAB output interface module 106 among the embodiment one, just repeats no more at this.
