The utility model discloses a compact structure has adopted the fire prevention frame of special material, has set up eight loudspeaker unit passageways, has realized the directive property of audio for the broadcast music can provide high -quality music effect.
Description
Technical field
This utility model relates to a kind of sound reproduction equipment, in particular to a kind of 8 passage active sound columns of directivity DSP.
Background technology
Existing sound column, can be divided into by whether carrying power amplifier: active sound column and passive column.By purposes can rough segmentation be: specialty sound column, home theater sound column, multimedia sound column.By enclosure material can rough segmentation be: plastics sound column, aluminum sound column, wood sound column etc..It is said that in general, the effect of aluminum sound column and wood sound column has a certain guarantee, but the process of spraying paint of only high cost, and otherwise the outward appearance of wood sound column is the most noticeable, and low-grade multimedia basic product just can use wood sound column.The sound column of some professional purpose also can use wooden material, but is usually the clamping plate used, and adds process of spraying paint, and effect also can be protected.Plastics sound column is the lowest due to outer cover intensity, and general effect is poor.Existing sound column be usually by arranged into an array for multiple speakers, produce linear sound, this design in actual use, owing to each speaker is all directed towards a direction so that the audio of side or position, back is poor, it is impossible to meet actually used demand.
Chinese patent application publication No. CN202168200U, March 14 2012 Shen Qing Publication date, in the utility model application patent of entitled " a kind of Multi-angle sound post ", disclosed Multi-angle sound post includes cylindrical body, at least two installed surface the most sequentially it is provided with on described cylindrical body lateral wall, two adjacent installed surfaces are positioned in different planes, each installed surface is provided with at least one speaker, described cylindrical body is provided with six installed surfaces, and each installed surface is sequentially staggered and is arranged in cylindrical body.Although this Multi-angle sound post can realize the polytropism of audio, but structure is complicated, profile heavy, and tonequality adjusts difficulty, and careful must adjust position in using just has optimum efficiency with inclination angle.
Utility model content
This utility model aims to provide a kind of 8 passage active sound columns of directivity DSP, poor to solve existing sound column audio, it is impossible to the problem meeting actually used demand, improves sound column device structure, the polytropism of audio is better achieved.
A kind of 8 passage active sound columns of directivity DSP, including sound column casing, described sound column casing is arranged in a quadra, the front of described sound column casing is provided with string loudspeaker unit, being further fixed on voice unit on described loudspeaker unit, the back side of described sound column casing is provided with the side upper/lower terminal of DSP display screen and sound column casing and is respectively arranged with sound column connecting hole.
Further, the quantity of described loudspeaker unit is eight, and each loudspeaker unit connects independent frequency divider.
Further, described loudspeaker unit is cylindrical, and the front of described sound column casing offers and is provided with three loudspeaker unit fixed bits on the installing hole mated with described loudspeaker unit, and described installing hole.
Further, the quantity of described voice unit is three, is located along the same line.
Further, described quadra is that the connection of fireproof aluminium section bar matter forms.
The utility model has the advantage of: these a kind of 8 passage active sound columns of directivity DSP; three loudspeaker unit fixed bits it are provided with on the installing hole mated with loudspeaker unit; thus realize high pitch polytropism; acoustical quality is good; it is also provided with the quadra of fireproof aluminium section bar matter so that this utility model is preferably protected.
