Abstract
The utility model discloses a broadly-radiated sound field three-frequency-division stereo loudspeaker which comprises a rectangular case body. A basetone loudspeaker is arranged on the right half side on the front side of the case body, two high pitch loudspeakers are arranged on the left half side on the front side of the case body, a mid-frequency loudspeaker is arranged on the right half side on the top surface of the case body, and two top high pitch loudspeakers are arranged on the left half side on the top surface of the case body; the basetone loudspeaker and the top high pitch loudspeakers are concave toward the inside of the case body, and a vertical sound insulation board is arranged in the case body, so that the high pitch loudspeakers and the top high pitch loudspeakers are separated from the basetone loudspeaker and the mid-frequency loudspeaker; the loudspeakers on the case body are connected through a three-division frequency divider and an audio input bus. The structures of the high pitch loudspeakers, the mid-frequency loudspeaker and the basetone loudspeaker are respectively arranged on the front side and the top surface of the loudspeaker, the high pitch loudspeakers are concave toward the inside of the case body, so that the sound field generated by the loudspeaker can be broad, the sound and the sound pressure can be distributed uniformly, the microphone can not easily lead to howling, and the feeling of layers is strong.
Description
Technical field
The utility model relates to a kind of loud speaker, especially a kind of three frequency division boombox.
Background technology
At present, carry out music appreciation and when giving song recitals,, make sound, the better equiblibrium mass distribution of sound pressure energy, special loud speaker therefore occurred for the reasonable use space indoor.Now the loud speaker of modal indoor special use mainly contains two kinds on the market: a kind ofly be made up of casing, woofer and two high pitch loudspeakers, and all loud speakers all are installed in the front of casing, such structure is in use because the high pitch deficiency, can cause sound field narrow and small, sound, acoustic pressure skewness, can make the people produce constriction, when using microphone to carry out indoor performance, utter long and high-pitched sounds owing to microphone produces over against high pitch loudspeaker easily simultaneously.The loud speaker of another kind of indoor use is that a plurality of high pitch loudspeakers are installed on the front of casing, though it has solved the problem of high pitch deficiency, but microphone produces the problem of uttering long and high-pitched sounds and does not still solve over against high pitch loudspeaker, and the distribution of sound, acoustic pressure is also unbalanced, and because the high pitch loudspeaker of installing is many, therefore need must be bigger with cabinet design, can influence and install and attractive in appearance.The boombox that also has a kind of wide spoke sound field now, this loud speaker is separately positioned on high, medium and low sound loud speaker on several of casing, though this spline structure makes high pitch abundance, wide, the difficult generation of sound field utter long and high-pitched sounds, also reduced simultaneously the volume of casing, but the level of its music is only clear, the skewness weighing apparatus of acoustic pressure.
The utility model content
The purpose of this utility model is: a kind of wide spoke sound field three frequency division boombox is provided, and its volume is little, and sound field is wide, sound, acoustic pressure distributing equilibrium, and difficult generation is uttered long and high-pitched sounds, and the stereovision of sound is strong, to overcome the deficiencies in the prior art.
The utility model is achieved in that wide spoke sound field three frequency division boombox, the casing that comprises cuboid, the right half side woofer that is provided with in the casing front, be provided with two high pitch loudspeakers casing front left half side, at the right half side Squawker that is provided with of box top, be provided with two top high pitch loudspeakers box top left half side; Woofer and top high pitch loudspeaker be to the casing sunken inside, and be provided with vertical sound panel in casing, makes between high pitch loudspeaker and top high pitch loudspeaker and woofer and the Squawker to be separated; Be connected with the audio frequency input bus by the three frequency division frequency divider between the loud speaker on the casing.
The side and the back side at casing are equipped with the installation screw.
Be provided with two panels with the high pitch loudspeaker adjacency, the surface composition rectangular surfaces of high pitch loudspeaker and panel casing front left half side; Be provided with two top panels with top high pitch loudspeaker adjacency, the surface composition rectangular surfaces of top high pitch loudspeaker and top panel box top left half side.
Owing to adopted technique scheme, compared with prior art, the structure that the utility model is provided with high, medium and low sound loud speaker respectively at the front and the end face of loud speaker, and make high pitch loudspeaker to the casing sunken inside, the sound field that loud speaker is produced is wide, sound, acoustic pressure distributing equilibrium are difficult for that again microphone is caused and utter long and high-pitched sounds; And adopt the three frequency division frequency divider to connect between the high, medium and low sound loud speaker, to improve the stereovision of sound.The utility model is simple in structure, makes easily, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the structure of wide spoke sound field three frequency division boombox as shown in Figure 1, make the casing 1 of a cuboid, right half side installation woofer 2 in casing 1 front, two high pitch loudspeakers 3 of left half side installation in casing 1 front to casing 1 sunken inside, and at two of the left half side installations in the casing 1 front panel 4 with high pitch loudspeaker 3 adjacency, the surface composition rectangular surfaces of high pitch loudspeaker 3 and panel 4; Right half side installation Squawker 5 at casing 1 end face, two of the left half side installations of casing 1 end face to casing 1 sunken inside top high pitch loudspeaker 6 and with the top panel 7 of top high pitch loudspeaker 6 adjacency, the surface composition rectangular surfaces of top high pitch loudspeaker 6 and top panel 7; And a vertical sound panel 8 is installed in casing 1, sound panel 8 is separated high pitch loudspeaker 3 and top high pitch loudspeaker 6 with woofer 2 and Squawker 5; Be connected with the audio frequency input bus by the three frequency division frequency divider between the loud speaker on the casing 1; All load onto installation screw 9 at the side and the back side of casing 1 at last.
Owing to adopted the Audio Processing method of salary distribution of three frequency division, make that full abundance between the high, medium and low sound, sound field are open, be rich in level, four cavitys that constituted four reflection high pitchs to the high pitch loudspeaker and the panel of casing 1 sunken inside, make sound reflect alternately, thereby make the distribution of sound, acoustic pressure balanced more; In addition, because it is concentrated relatively that high pitch loudspeaker is installed, therefore woofer 2 has adopted the structure of a shared Room with Squawker 5, and separates with a sound panel between high pitch loudspeaker and low, the Squawker, thereby has reduced 6 needed volumes of loud speaker of casing 1 installation.And vertical floor stand, the lifting of vertical zenith, the lifting of horizontal zenith or horizontal floor stand are installed for for convenience casing 1, therefore loaded onto installation screw 9 at the side and the back side of casing 1, make the utility model can not only adapt to various installations, and attractive in appearance, and can save installing space; When concrete the making, can also by change high pitch loudspeaker towards, to obtain different high pitch effects.
