The technical essentials of the three-way loudspeaker box are that the three-way loudspeaker box comprises a box body, that bass horns, an alto horn, and high-pitch horns are disposed on a side surface of the box body, that the high-pitch horns are disposed on the side edgee of the alto horn in an inclined manner, and that installing intersection angles between the high-pitch horns and the alto horn are from 155 to 170 degrees. The three-way loudspeaker box has characteristics of compact structure, reasonably-arranged horns, multidimensional wide-angular diffusion of sound wave and is used in homes or entertainment venues.
Description
Technical field
The utility model relates to a kind of audio amplifier, more particularly, relates in particular to a kind of three frequency division audio amplifier.
Background technology
Current Karaoke (KTV) audio amplifier is joined two frequency divisions of 3 cun of cone high pitchs or the three frequency division audio amplifier that same specification loudspeaker unit is made mainly with 8 cun, 10 cun, 12 cun bubble continuous ring limit basses.Because although 12 cun, 10 cun, the 8 cun bubble continuous ring limit bass horn frequency response upper limits can arrive 4KHz, conventionally only to 1KHz, just with different gradients, tumble, energy sharp-decay.Although the frequency response lower limit of 3 cun of cone high pitchs all marks and can arrive 1.3KHz, in fact their frequency response lower limit has generally just tumbled downwards with different gradients to 3KHz place.Effective frequency response lower limit of 3 cun of cone high pitchs is low not, and the sensitivity of 3 cun of cone high pitchs is low, power is also little, if without electric capacity frequency division, easily burnt out, but high pitch is after electric capacity frequency division limits energy, in response frequency, moves, frequency response lower limit is low more not.Therefore these two classes loudspeaker form after audio amplifier, generally between 1KHz～5KHz, have serious energy shortcoming (the local sound that lacks in middle pitch region), and frequency response curve depression is uneven, causes the reduction degree of audio amplifier in practical application not high, sound shortcoming roundness degree and lightness.Two frequency divisions of prior art or three frequency division audio amplifier be not in order to lose effective upper limit of bass horn, made it to be connected, all to adopt with 3 cun of cone high pitchs as much as possible bass horn without inductance, do not add the direct-passing mode of electric capacity, even if but like this, still cannot improve the problem of separating audio amplifier shortcoming middle pitch.Because sound is owed in part, audio amplifier cannot truly reduce the sound of playback song (program source), the middle pitch energy of 1KHz to 4KHz is very weak, while listening to the music, feel audio amplifier sound retrude, shortcoming sound details, shortcoming lightness, roundness degree, during singing, perceived sounds is not penetrating, sound dry, the effort relatively of singing.
In addition, the audio amplifier that prior art design is produced is in order to get a promotion the frequency response upper limit of bass horn, make it under pass-through state as far as possible with 3 cun of cone high pitch relative equilibriums be connected, make audio amplifier be unlikely to owe sound too many, conventionally adopt the voice coil loudspeaker voice coil that diameter is little, but the power that the voice coil loudspeaker voice coil of minor diameter can bear is relatively little again, and the frequency response upper limit is done relatively highly, frequency response lower limit is just low not, and F0 can move up, so just make the frequency response lower limit of audio amplifier low not, thereby make the frequency response narrowed width of audio amplifier.In order to make lower, the lower-powered 3 cun of cone high pitchs of sensitivity comparatively safe stable, in practicality, prior art is not bass straight-through (but inductance is pressed eminence), high pitch carries out frequency division (being actually current limliting limits the quantity of) through a little electric capacity, after limiting the quantity of through electric capacity frequency division limit, audio amplifier has just had energy shortcoming in various degree between 1KHZ～5KHZ, the local sound that lacks, shows on frequency response curve it is the depression that has " mountain valley shape ".
Utility model content
The purpose of this utility model is the deficiency existing for above-mentioned prior art, provides a kind of compact conformation, loudspeaker to arrange rationally, makes sound wave can reach the three frequency division audio amplifier of stereo multi-dimensinal wide-angle diffusion.
The technical solution of the utility model is achieved in that a kind of three frequency division audio amplifier, comprise casing, on the side of casing, be respectively equipped with bass horn, mediant trumpet and loudspeaker, wherein said loudspeaker is inclined at the side of mediant trumpet and the installation angle of loudspeaker and mediant trumpet is 155～170 °.
In above-mentioned a kind of three frequency division audio amplifier, described loudspeaker has two, is inclined at respectively the both sides of mediant trumpet, and the installation angle of two loudspeakers and mediant trumpet is 155～170 °.
In above-mentioned a kind of three frequency division audio amplifier, described bass horn has two, and two bass horns are corresponding two the loudspeaker downsides and identical with corresponding loudspeaker setting angle that are arranged on respectively; Further, on the casing of the outer downside of described two bass horns, be respectively equipped with paraphase hole.
In above-mentioned a kind of three frequency division audio amplifier, described bass horn is one, and this bass horn is arranged under mediant trumpet and is identical with the setting angle of mediant trumpet; Further, the casing under described bass horn is provided with paraphase hole.
In above-mentioned a kind of three frequency division audio amplifier, the casing of described bass horn, mediant trumpet and installed surface periphery, loudspeaker place is provided with protection net.
The utility model adopts after said structure, by by mediant trumpet design and installation at middle position, loudspeaker design and installation in the both sides of mediant trumpet, the installation angle of loudspeaker and mediant trumpet is 155～170 °, make audio amplifier not only can realize Sound image localization accurately, the reduction degree of sound is rationally promoted and is optimized, also make this audio amplifier can reduce more realistically stereo multi-dimensinal spatial impression and the presence of modern record type, make people's sense of hearing just as on the spot in person, make us audition sensation true, natural, feel more warm, easily empathize.This arrangement mode can also effectively be widened the horizontal coverage rate of sound wave, and the stereo multi-dimensinal sound wave of realizing wide-angle wide cut covers, and the sound field positional accuracy of audio amplifier is promoted greatly.
