Embodiment
Now in conjunction with the accompanying drawings the utility model is done further and specified.
As Fig. 1,2, shown in 3, what show is a kind of syndeton that each sound channel of the utility model combines with general TV when having two rotatable loud speakers, upper left loud speaker 21 and lower-left loud speaker 22 are equipped with in television cabin 1 left side, they are by modular support 23,24,25 are fixed in TV left side, wherein, the right side of support is connected with television cabin 1 left hand external, its concrete mode can have a variety of, in this measure one example, have the reversed F-typed of bending as support 23, at its right side planar section through hole 231 that screws, through hole is at least two and highly equal, on TV shell 1, beat screwed hole corresponding, then can utilize screw support 23 to be fixed in the side of casing 1 with it.The fixed form of support 24,25 can be approximate with support 23.Like this, can between support 23,24, place upper left loud speaker 21, between support 24,25, place lower-left loud speaker 22.
After allowing loud speaker 21 put into, have location and rotating flexibility preferably, also can adopt multiple mode.In this measure one example, as making cylindrical projections part 232, make groove 211 at upper left loud speaker 21 center of top counterparts simultaneously, like this in support 23 downsides central authorities, can guarantee the fixing firm of support and loud speaker, can make upper left loud speaker 21 again serves as the axle rotation with cylindrical protrusion 232.Lower-left loud speaker 22 is if fixing, and principle is same therewith, and the screw through-hole 241,251 of support 24,25 and the cylindrical projections part 242 of support 24 are with support 23.
Fixing and the connected mode of upper right loud speaker 31 and bottom right loud speaker 32 can be identical with the left side.
Rotatable speaker unit described in the utility model is not to be hung on the outer left and right sides of television set, because emerged in large numbers a large amount of free-standing speaker units at present, this free-standing loud speaker is can erect to place the TV both sides, but not being tightly be hung on about TV, neither be one with TV.As shown in Figure 4, showed a kind of rotatable free-standing speaker unit, left speaker has upper left loud speaker 21 and lower-left 22 loud speakers, and right loud speaker has upper right loud speaker 31 and bottom right loud speaker 32.TV left side voice signal output source can be divided into two holding wire branches and be connected to upper left and the lower-left loud speaker, and TV right side voice signal output source also can be divided into two holding wire branches and be connected to upper right and the bottom right loud speaker.The locus that left and right sides two stands has support section respectively and holds single loud speaker.At this, also can adopt the rotating shaft among similar Fig. 2 and Fig. 3 so that single loud speaker is easier to rotation.
As shown in Figure 5, existing sound reception principle to rotatable speaker unit is described in further details.As figure, the O point is the video screen central point, its left side is upper left loud speaker 21 and lower-left loud speaker 22, general when the equal subtend of all loud speakers dead ahead, then C can obtain preferable sound effect to the audience in the D point, because sound has higher intensity certainly on the forward-propagating direction, with N in scheming to sound be example, it certainly will have intensity preferably when passing to the C point, sound then and can decay to some extent at the E point, simultaneously E point audience hears that the D point sound on another right side is more weak, and considers the factor after itself and the right side sound mix, certainly will feel not so good on audio.Particularly there is stronger directivity requirement the high pitch loudspeaker unit to sound field, and this point just shows more outstandingly.
In disclosed Chinese patent 200520034698.5, mention left and right difference is rotated to the inside, to aim at dead ahead audience A, though this moment, A point intensity was the highest, effective, the audience that B point, E are ordered all can not satisfy the demands.The utility model has then well solved this problem of attending to one thing and lose sight of another, and that makes two respectively with left and right loud speaker exactly, and can rotate in the horizontal plane.As A, B, when the E point all has the audience, can regulate upper left or the lower-left loud speaker, another laterally rotates slightly towards the dead ahead to make one, like this, because the M sound wave is sent to the E point, the audience that E, B are ordered also can satisfy the demands, thereby reaches a kind of equilibrium, promptly no matter with TV over against the still right audience of side slightly, the sound intensity that it is felt and sound effect are close, do not have the branch of obvious power.
In addition, when having only the audience to be positioned at the A point, because personal like's difference, he likes changeing in the two-loudspeaker of the left and right sides directly to the A point, at this moment, because the rotatability of four independent loud speakers, determined to form multiple different sound effect style, for example, with upper left loud speaker 21 and upper right loud speaker 31 over against the place ahead, and will lower-left loud speaker 22 and bottom right loud speaker 32 outer commentaries on classics aim at indoor walls, rely on the sound of reflected back of wall and forward (as N among Fig. 5 to) sound mix forms different-effect.
As the free-standing loud speaker among Fig. 4, its effect principle similar the above.
Based on above-mentioned principle, described in the utility model, have at least a left speaker to rotate in the horizontal direction, have at least a right speaker to rotate in the horizontal direction, that is to say, four loud speakers can horizontally rotate, also can be that upper left loud speaker 21, upper right loud speaker 31 maintain static as conventional loud speaker, and only lower-left loud speaker 22, bottom right loud speaker 32 can horizontally rotate, perhaps approximate combination, and these variations can decide according to product demand.
Above-mentioned only is a preferable enforcement example of the present utility model; can not limit protection range of the present utility model with this, these those skilled in the art are not breaking away from the many variations of making under the utility model spirit and scope situation and are modifying all within the scope that the utility model covers.
