Description
Technical field
The utility model relates to a kind of stereo set, and more particularly, the utility model relates to a kind of digital sound playback equipment.
Background technology
Along with the development of digital multimedia technology and the increase of portable memory kind, MP3 player, digital recorder, Digital camera, digital camera etc. many kinds of hand-held multimedia digital devices have appearred, for example on the market.The inner removable memory that all is built-in with storage signal of these devices, USB flash disk of flash memory (flash memory), portable hard drive, band USB interface and flash memories or the like for example, the media signal of various format and contents then with digital store in different types of memories.For example, the MP3 music player is if the music content data in increase or the updated stored device are mainly carried out by band usb line, RS232 or parallel port and after computer is connected at present.
There is following shortcoming in present this structure: owing to the mobile memory that all adopts hardware and/or software format to be not quite similar such as devices such as MP3 player, digital recorder, Digital camera, digital cameras (dish or card), cause the poor compatibility of the mobile memory between the different digital multimedia equipment, can not mutual general mobile memory; Since the poor compatibility between the software and hardware of the mobile memory on the different digital multimedia devices, people do not want to be provided with and can carry out multi-functional, the compatible good card reader that data are read to various storage cards with regard to natural ground.So, the tourism or the preceding people that go on business must prepare to carry different mobile memories, lose time and financial resources do not say, in case trip outside, deficiency occurs because situation changes the mobile memory capacity that causes certain class, and another kind of mobile memory capacity is still rich, people can not carry out regulate supplies betwixt, adopt and have a surplus, thereby cause passively, damaged the quality of public and private activity in the trip with tonifying for the deficiency.
In this regard, it is the computer active audio amplifier that 200420043624.3 Chinese patent application file discloses a kind of MP3 of having playing function that application number is arranged, comprise main sound box and auxiliary audio amplifier, the power amplifier plate is arranged in the main sound box, be provided with the MP3 playing circuit in the main sound box, the MP3 playing circuit comprises DSP control/decoding unit, and DSP control/decoding unit periphery is connected with memory body, infrared receiving terminal, USB interface and audio interface respectively, and the output of DSP control/decoding unit connects power amplifier; Also dispose an Infrared remote controller, be used to control the work of DSP control/decoding unit.Tool claims: because hardware MP3 player and computer active audio amplifier are organically combined, even host computer is in off-mode, also can play the MP3 music file.And it is with low cost, and is simple to operate, can be widely used in the media play of popular desktop computer.But this device still has Multimedia Mobile equipment in the function singleness of storage card aspect reading, the disadvantage of poor compatibility.
Summary of the invention
Above-mentioned shortcoming at prior art, the technical purpose that the utility model will reach is that a kind of electronic plane audio amplifier will be provided, and this plat sound box can dock different digital memory card quickly, can read multi-medium data on the different digital memory card, have very strong Card Reader compatibility multi-functionally.
For this reason, technical solution of the present utility model is a kind of portable digital plat sound box, be equiped with loudspeaker, analog to digital converter, MP3/WMA decoder, microcontroller, operation keys and power circuit in this plat sound box, and also being integrated with the card reader of digital memory card in the described plat sound box, described card reader is connected with described microcontroller by the card reading interface circuit.Although traditional built-in removable memory volume is very little, removable in theory, but belong to fixed setting owing to removable memory is built-in, in fact removable memory has been lost function convenient, flexible, that upgrade, can not bring convenience to the user.Notice this shortcoming, and notice the characteristics of the stored digital card reader of showing up prominently, the utility model is the integrated card reader of digital memory card in plat sound box, inner and the built-in microcontroller of this kind card reader is connected, and the multiple digital memory card of can also pegging graft in its bayonet socket that exposes, read the multi-functional of different digital storage card as long as give card reader by software or hardware, the utility model just can only depend on the different digital memory card of transposing to come flexibly, read the multi-medium data of renewal easily, more traditional fixing built-in removable memory is flash memory (flash memory) for example, portable hard drive, it is more convenient that USB flash disk of band USB interface and flash memories or the like has, therefore the data read ability also just has very strong Card Reader compatibility flexibly.
For realizing flexible, the convenience of card reader preferably, card reader described in the utility model comprises the spininess interface and the identification of docking with described storage card and reads the processor of data on the storage card.Described card reading interface circuit is a usb circuit, and interface circuit can also be parallel port, serial ports, PCMICA interface or IEEE 1394 interfaces certainly.Described card reader has 18 needle interfaces of compatible 7 pins, 9 pins and 18 pin pinned storage cards.Described card reader has the storage card electromechanical structure that reads Memory Stick (memory stick), MMC Card (multimedia card), SD Card (safe digital card) and XD card etc. at least.The storage card that is mainly used in storing image data so also can be used for storing and the playing back music data, and is flexible multi-purpose.
For obtain best portable or pocket structure in conjunction with up-to-date loudspeaker technology, described loudspeaker are the plane formula loudspeaker; Described plat sound box is that pocket is renovated pack arrangement, described plane formula loudspeaker constitute one of to be renovated, described microcontroller, MP3/WMA decoder, analog to digital converter, operation keys and power circuit all are installed in the renovating of this plane formula loudspeaker one side, and also accommodate other digital mobile device in the space that the another side of this bag is renovated.Also comprise portable power supplies in described plane formula loudspeaker the renovating on one side.Described plat sound box also is provided with the audio frequency accessory power outlet of described loudspeaker of gating or external earphone.Described electronic plane audio amplifier outside also is provided with for fixing to the cingulum on the human body.
In a word, the utility model is simple in structure, and effect is obvious, and is easy to utilize.
