Description
Technical field
The utility model relates to a kind of audio amplifier, specifically be a kind of multimedia loudspeaker box.
Background technology
At present, allegro life is more and more recognized people, and suitable amusement is very effective to alleviating living pressure.Therefore the abstract the recreational consumption of family is in quick growth, and digitized stereo set is also more and more universal, and traditional audio amplifier all is that function of use is single as external playback equipment, and when playing, power amplifier will connect DVD or computer could be play; This audio amplifier only is applicable to home theater or a certain fixed-site, if the user will travel outdoors, needs also to want strip sowing to put equipment outside the band audio amplifier, and be very much inconvenience; Along with the application of Internet technology, people need the song on the download network, and imprinting becomes CD then, play by power amplifier on DVD equipment again, and the cost of abstract the recreational consumption is too high like this, can not be popularized.Popularizing of memory device movably particularly proposed very big challenge as the appearance of USB device, storage card to traditional audio amplifier.
In addition, the user will travel outdoors, and need carry audio amplifier equipment, and for the audio amplifier of large volume slightly, moving is very much difficulty, and in the process that moves, because the casing unbalance stress is fragile.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of power amplifier band USB slot, the multimedia loudspeaker box of card reader.
The technical solution of the utility model is, provide a kind of multimedia loudspeaker box: comprise the casing, loudspeaker, the power amplification device that are formed by connecting by protecgulum and bonnet with following structure, described power amplification device comprises power amplifier, knob, described power amplification device also comprises USB controller, card reader, described USB controller is connected with a USB slot, described card reader and USB controller also are connected with a display screen, described power amplifier input is connected with decoder, and described decoder input is connected with the output of USB controller and card reader respectively.
As further improvement, described casing top also is provided with a telescopic pull bar, and bottom half also is provided with at least one pair of roller, like this when mobile audio amplifier, easily, conveniently.
During broadcast, only need the USB device connection is located in the USB slot of USB controller on the power amplification device, or with in the SD/MMC card insertion card reader, the audio file in USB device or the storage card can be analyzed, be read to USB controller or card reader, audio file is converted into the analogue audio frequency file that can be read by power amplifier or directly play from loudspeaker by decoder.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, power amplifier needn't be connected DVD or computer, only needing a USB device just is inserted on the USB controller of power amplification device can displaying audio file, because the erasable property of USB device, can in time download from the Internet, the song of updated stored, easy to use, quick, the USB device volume is little portable in addition.
2, the employing of roller and pull bar, it is big because of volume to have overcome sound equipment, and the shortcoming that be difficult for to move is travelled outdoors and is provided convenience for carrying audio amplifier.
