Description

Combined box

Technical field

The utility model relates to audio amplifier, more particularly, relates to a kind of combined box that comprises high sound box with sound and woofer.

Background technology

Generally include casing, loudspeaker and bass horn in traditional bookshelf audio amplifier.Wherein, normally be provided with upper and lower two loudspeaker installing holes in the front of casing, then loudspeaker be loaded on the top installing hole, bass horn then is loaded on the bottom installing hole.In order to produce good sounding effect, normally be provided with pore, so that the air of box house can communicate with extraneous air in the front or the back of casing.When pore was located at the casing back, in use must guarantee had suitable distance between casing back and the metope, can not have other object to be close to the casing back and pore is blocked, because this all can influence the sounding effect of audio amplifier.Equally, be located at casing when positive when pore, it is positive and pore is blocked to have other object to be close to casing.As seen, this audio amplifier has special requirement for placing environment, when there is object its casing front or back, will blocks pore and influences the sounding effect of audio amplifier.

The utility model content

At the above-mentioned defective of prior art, it is higher for placing environmental requirement that the utility model will solve existing bookshelf audio amplifier, and the pore of its casing front or back easily is blocked and influences the sounding effect problem.

The technical scheme that the utility model solves the problems of the technologies described above is: construct a kind of combined box, comprise a high sound box with sound and a woofer; Wherein, the front of described high sound box with sound is provided with the loudspeaker installing hole, and the bottom surface is provided with a pore, and all the other each faces are enclosed construction; The front of described woofer is provided with the bass horn installing hole, and end face is provided with a pore, and all the other each faces are enclosed construction; The underrun support column of described high sound box with sound is installed in the end face of described woofer, and a gap is arranged between the end face of its bottom surface and described woofer, and the pore of the pore of its bottom surface and described woofer end face over against.

In the utility model, the front of described woofer is preferably incline structure, and and the bottom surface between be 65-75 degree angle, preferably be 70 the degree angles.In addition, the junction of the front of described woofer and bottom surface preferably is cut and forms a vertical plane.

In the utility model, the front of described high sound box with sound is preferably opposite low dip structure, and and end face between be 83-90 degree angle, preferably be 85 the degree angles.

In the utility model, the gap between the bottom surface of described high sound box with sound and the end face of woofer can be 0.5-3 centimetre; In addition, the pore of the pore of described high sound box with sound bottom surface and woofer end face can be the rectangular opening of same size.

By such scheme as can be known, high sound box with sound can be by pore and the gap between two audio amplifiers and outside ventilation of its bottom surface, woofer also can be by pore and the described gap and outside ventilation of its end face, that is to say, this combined box can 360 the degree exhausts, thereby broken through the placement of traditional audio amplifier and the restriction of sound field diffusion aspect, make small-sized bookshelf audio amplifier can set up grand large presence, even, also can keep good sounding effect in that the environment of foreign material is arranged.

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the right view of Fig. 1;

Fig. 4 is the B-B cutaway view of Fig. 3;

Fig. 5 is the upward view of high sound box with sound shown in Fig. 1;

Fig. 6 is the vertical view of woofer shown in Fig. 1.

Embodiment

A preferred embodiment of the present utility model such as Fig. 1 are to shown in Figure 6, and as can be seen from the figure, this combined box comprises a high sound box with sound 100 and a woofer 200, and high sound box with sound is loaded on top, and woofer is loaded on the bottom.

As can be seen from the figure, be provided with loudspeaker installing hole 101 in the front of high sound box with sound 100, and be provided with a pore 102 in its bottom surface, all the other each faces are all enclosed construction; In addition, around pore 102, be provided with four screws 103 that are used to install support column.Correspondingly, be provided with bass horn installing hole 201 in the front of woofer 200, and be provided with a pore 202 at its end face, all the other each faces are all enclosed construction.Wherein, the woofer back is an aluminium matter backboard, can be used for installing input signal binding post, volume control knob etc.In addition, around pore 202, also be provided with four screws 203 that are used to install support column.

As can be seen from the figure, in the present embodiment, the pore of high sound box with sound bottom surface 102 is the rectangular opening of same size with the pore 202 of woofer end face, when specifically implementing, can also be the pore of other switch, circular hole for example, elliptical aperture etc.; Simultaneously, four metallic support posts 300 of the underrun of high sound box with sound 100 are installed in the end face of woofer 200, and the pore that makes the pore of high sound box with sound bottom surface and woofer end face mutually over against; These four support columns can be common screw, and its number can also be three, five or more.

As can be seen from the figure, between the end face of the bottom surface of high sound box with sound and woofer a gap is arranged, its size can be 0.5-3 centimetre, thus, high sound box with sound can be by its pore 102 and this gap and outside ventilation, and woofer also can be by its pore 202 and this gap and outside ventilation.The high sound box with sound of this combined box and woofer can 360 the degree exhausts, thereby broken through the placement of traditional audio amplifier and the restriction of sound field diffusion aspect, make small-sized bookshelf audio amplifier can set up grand large presence.During use, place even audio amplifier is close to metope, the front in this gap, the left side and the right side still can communicate with extraneous air; Equally, when one of them of audio amplifier, two even three faces were blocked by exterior object, this gap still had at least one face to communicate with extraneous air.So this sound is more much lower than traditional audio amplifier for placing environment requirement, even in that the environment of foreign material is arranged, also can keep good sounding effect.

In the present embodiment, the front of woofer is an incline structure, and and the bottom surface between be 70 the degree angles; Simultaneously, the front of high sound box with sound is opposite low dip structure, and and end face between be 85 the degree angles.This structure can produce focus and phase place is corrected (Focus Point and Phasing Correction) effect, corrects high and low sound significantly and arrives the phase place and the time difference of listening the hearer, makes sound localization and gathering reach unprecedented absolutely accurate.During concrete enforcement, the front of woofer and the angle between the bottom surface can change between the 65-75 degree, and the front of high sound box with sound and the angle between the end face can change between the 83-90 degree.

In addition, in the present embodiment, the front of woofer 200 and the junction of bottom surface have been cut a bit of, thereby form a vertical plane.Because inclinations that face up of woofer makes when this combined box is positioned on the table top, the bass that it sent can not form 90 degree reflections with table top and produce muddiness and sound dyes.
