Description
Technical field
The utility model belongs to stage sound box technology field, specifically relates to a kind of 20 cun of high-power light of stage audio amplifiers.
Background technology
High-power light of stage audio amplifier in the market, audio amplifier is together with being seldom fused into an integral body in lighting system design.All separately independent.On light of stage loudspeaker box structure, be generally combined set, 15 cun of above super-bass loudspeaker box separate units add a low high-pitched sound box unit in addition and support the use.This suit is design separately, has increased the cost of each side, and different unit combination has increased design difficulty and the harmony of frequency divider.Different environment, place, personnel's operation all can affect sound reproduction effect.Meanwhile, for meeting the needs of the different places such as broadcast, meeting, stage performance, need to increase various electric power connection lines and interface, these annexes have increased the load of sound, make both poor sound quality.
Also has a kind of mostly Shi Eryin road two divided-frequency separate unit series that is less than on the high-power light of stage loudspeaker box structure of 15 cun, this two sounds two divided-frequency series sound is at playback time, low, in, it is balanced that high pitch cannot reach on audio, cannot meet reduction and the playback of the basic, normal, high sound of music, resolution is inadequate.This separate unit bass part is that selvedge+cone drives radiation, and high frequency unit is that bugle compression drives radiation, and low frequency cell cannot meet high-power output requirement increasing on market, and audio amplifier cannot mate mutually with high-power power amplifier.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, a kind of 20 cun of high-power light of stage audio amplifiers are provided, by bass unit, alto units, voice unit are incorporated in audio amplifier same panel, form San Yin road three frequency division, met the frequency range of whole audio frequency needs, avoid the mutual interference of electronic component phase, there is the features such as modern design, high directive factor, constant directive property; And by light of stage built in sound box Bluetooth chip, realize mobile phone music and share, broken away from the constraint of electric wire.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of 20 cun of high-power light of stage audio amplifiers, comprise wooden box body, and wooden box body panel is set on described wooden box body, the described wooden box body panel upper left corner arranges mediant trumpet; The described wooden box body panel upper right corner arranges loudspeaker; Described mediant trumpet and loudspeaker below arrange bass horn; Described bass horn below arranges two airducts, and described airduct plays inverting function, prevents acoustic short circuit simultaneously.
As preferably, on described bass horn, mediant trumpet and loudspeaker, loudspeaker iron net is set, described loudspeaker iron net is for dustproof.
As preferably, described wooden box body both sides arrange handle, and described handle is used for mentioning audio amplifier; Plastic surface shell is also set on the corner angle of described wooden box body, and described plastic surface shell is for shockproof, shatter-resistant.
As preferably, described loudspeaker, mediant trumpet, bass horn and airduct arrange case ring outward.
As preferably, described bass horn also arranges reflex reflector lens outward, and described eyeglass, for sky light, increases the lighting effects of stage.
As preferably, between described loudspeaker, mediant trumpet and bass horn, dividing plate is set, described dividing plate can prevent phase mutual interference between loudspeaker, mediant trumpet and bass horn.
The beneficial effect the utlity model has: by bass unit, alto units, voice unit are incorporated in audio amplifier same panel, form San Yin road three frequency division, met the frequency range of whole audio frequency needs, avoid the mutual interference of electronic component phase, there is the features such as modern design, high directive factor, constant directive property; And by light of stage built in sound box Bluetooth chip, realize mobile phone music and share, broken away from the constraint of electric wire.Therefore the utlity model has the features such as simple in structure, reasonable in design.
