Description
Technical field
The utility model relates to music equipment field, and it is good to relate more specifically to a kind of play sound effect, miniature loudspeaker box simple in structure, easy to assembly, that low production cost is easy to apply.
Background technology
Continuous development along with science and technology, increasing video-audio playing system has appearred on the market, continuous maturation along with small-sized Play System technology, the miniature loudspeaker box system that matches is also more and more, present popular miniature loudspeaker box, exactly digital audio and video signals directly is input into audio amplifier from the USB mouth on the mainboard, again the D/A change-over circuit by built in sound box with signal processing after the audio amplifier of output again.The advantage that adopts USB speaker outwardly is to improve tonequality, because digital signal can not be interfered in transmission course, the degree of purity of signal is good, but the core of USB speaker is the D/A change-over circuit, and its conversion accuracy is very big to the performance impact of audio amplifier.The compact size of USB speaker is convenient for carrying, and dazzles cruel profile, modish fashion, and personalized collocation of colour, audio amplifier is fresh and clean.Integrate power amplifier, battery, twin loudspeaker, and this type of audio amplifier do not need long tone frequency channel wire, do not need external power supply, no matter be the pure and fresh rhythm as the high mountain and great rivers, still passionate DJ dance music can both drippingly extremely show to the greatest extent.
The miniature loudspeaker box that occurs on the market is the fore shell that loudspeaker are positioned at audio amplifier mostly at present, so when the fore shell of miniature loudspeaker box contacts with desktop or other objects, the just obvious variation of the audio of playing, because miniature loudspeaker box in use, often all be to carry to play at any time to use, fore shell can touch other objects unavoidably, therefore influences the play sound effect of audio amplifier.
Therefore the miniature loudspeaker box good, simple in structure, easy to assembly, that low production cost is easy to apply of needing a kind of play sound effect badly.
The utility model content
It is good that the purpose of this utility model provides a kind of play sound effect, miniature loudspeaker box simple in structure, easy to assembly, that low production cost is easy to apply.
To achieve these goals, the technical solution of the utility model is: a kind of miniature loudspeaker box is provided, be used to place loudspeaker, it comprises: lower casing, mesochite and upper casing, the two ends of described lower casing offer the loudspeaker containing cavity respectively, the bottom of described containing cavity is provided with horn bracket, the rectangular mount structure of described mesochite hollow and being installed on the described lower casing, the corresponding described loudspeaker containing cavity in the two ends of described upper casing offers outlet sound mouth and is installed on the described mesochite, the magnet of loudspeaker be carried on the described horn bracket and the basin chord position of loudspeaker in the rectangle frame of described mesochite and over against described outlet sound mouth.
Preferably, the top of described upper casing offers groove.Described groove is set avoids described outlet sound mouth directly to contact, influence the play sound effect of the utility model miniature loudspeaker box with external object.
Preferably, also include decoration, described decoration covers on the described groove, and described decoration is arranged to run through the mesh-structured of described decoration upper surface and lower surface over against described outlet sound mouth place.Described decoration is set has mesh-structured the more elegant in appearance of the utility model miniature loudspeaker box that can make.
Compared with prior art, in the utility model miniature loudspeaker box, the corresponding described loudspeaker containing cavity in the two ends of described upper casing offers outlet sound mouth and is installed on the described mesochite, the magnet of loudspeaker be carried on the described horn bracket and the basin chord position of loudspeaker in the rectangle frame of described mesochite and over against described outlet sound mouth.Even therefore the upper casing when the utility model audio amplifier contacts with external object, can not influence play sound effect yet.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
