A kind of reversible multimedia loudspeaker box
The utility model belongs to technology for loudspeaker box field, relates to a kind of reversible multimedia loudspeaker box.
Along with the rapid growth of home entertaining consumption and the extensive use of Internet technology, digitized stereo set is more and more universal.Traditional audio amplifier need to connect external playback equipment when using function singleness and playing.Along with popularizing of movable memory equipment, as the appearance of the equipment such as USB has proposed very large challenge to traditional stereo set.
In addition, common audio amplifier does not have stress point in the market, is not easy to carry.On audio amplifier, loudspeaker are fixed, and when condition runs into restriction and audio amplifier can only be placed in indoor certain position time, it is unalterable that loudspeaker point to.At present, common audio amplifier only has a placement surface, makes the loudspeaker can only be facing one direction, if to adjust loudspeaker towards, need to use other tool support sound boxes, troublesome poeration, and affect attractive in appearance.
Utility model content
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind ofly audio amplifier can be hung up, reversible multimedia loudspeaker box with USB slot.
The purpose of this utility model can realize by following technical proposal: a kind of reversible multimedia loudspeaker box, comprise by catch net, protecgulum, the casing that bonnet forms, it is characterized in that: on described casing, loudspeaker are installed, power amplification device, USB slot, display screen, decoder, on described casing, be also provided with an arrangement inclined-plane, described casing top is provided with groove, described casing top is also provided with the handle across groove, described handle is made up of the bend that is installed in the fixed part on casing and be connected with fixed part, on described handle, offer the through hole running through by fixed part, described power amplification device comprises power amplifier, knob, USB controller, described USB slot output is connected with USB controller input, described USB controller output end respectively with display screen input, decoder input is connected, described decoder output respectively with power amplifier input, loudspeaker input is connected, described power amplifier output is connected with loudspeaker input.
Further, described arrangement inclined-plane and loudspeaker are towards setting in a certain angle.
Further, described catch net covers front exterior surface completely.
Further, described display screen is chosen as LCDs.
Further, described display screen, USB slot, knob are all installed on the outer surface of casing.
Compared with prior art, the utility model power amplifier needn't be connected on DVD or computer, only a USB device need be inserted on USB slot, and USB controller by power amplification device just can displaying audio file, due to the erasable property of USB device, the song that can download in time, upgrade storage from the Internet is practical and convenient, quick; The utility model is simple in structure, is easy to carry, and in the time being subject to condition restriction, audio amplifier can be hung up; Can according to place and user's request adjust loudspeaker towards, thereby obtain better sound effect.

Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figures 1 to 4, this reversible multimedia loudspeaker box comprises by catch net 1, protecgulum 2, the casing that bonnet 3 forms, loudspeaker 4 are installed on casing, power amplification device 5, USB slot 9, display screen 10, decoder 11, on casing, be also provided with an arrangement inclined-plane 6, casing top is provided with groove, casing top is also provided with the handle 7 across groove, handle 7 is made up of the bend 71 that is installed in the fixed part 72 on casing and be connected with fixed part 72, on handle 7, offer the through hole 8 running through by fixed part 71, power amplification device 5 comprises power amplifier 51, knob 52, USB controller 53, USB slot 9 outputs are connected with USB controller 53 inputs, USB controller 53 outputs respectively with display screen 10 inputs, decoder 11 inputs are connected, decoder 11 outputs respectively with power amplifier 51 inputs, loudspeaker 4 inputs are connected, power amplifier 51 outputs are connected with loudspeaker 4 inputs.
Loudspeaker 4 on audio amplifier are fixed, must make loudspeaker 4 towards within the scope of sensing in order to obtain best sound effect.Arrangement of the present utility model inclined-plane 6 is with loudspeaker 4 towards being 30 degree equal angles settings, and will settle the placement location laminatings such as inclined-plane 6 and ground during as user, loudspeaker are 30 degree equal angles upward, thereby obtain better sound effect; User is in the time using audio amplifier but arrangement condition (as: ground humidity, area too little) restriction, and available rope, through through hole 8, is suspended on the first-class place of wall by audio amplifier.
When broadcasting, only USB device need be connected and is located on USB slot 9, and analyze, read the audio file in USB device by USB controller 53 on power amplification device, by decoder 11, audio file is converted into the analogue audio frequency file that can be read by power amplifier 51 or directly play from loudspeaker 4.Display screen 10 can show information, the broadcast sound volume in USB device, selects suitable volume by rotation knob 52, presses and rotates knob 52 and select the song of liking.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
