Realize best way of the present invention
With reference to the Fig. 1 in the accompanying drawing; shown an illustrated and claimed screen board formula loud speaker 81 in our international application (we case number P.5711) of common pending trial of same period therewith; it comprises the rectangular frame 1 that has resilient suspension 3, and described suspension a distributed acoustic radiation screen board 2 around its interior Zhou Zhicheng.As the transducer 9 of Fig. 4 explanation intactly and by oneself be installed on the screen board 2 or the interior preset bearing that limits by x and y on, the position in its orientation is by the calculating of explanation in our international application (we case number P.5711) of pending trial of same period therewith,, in screen board, screen board is resonated launch output with the emission bending wave.Transducer 9 is driven by a signal amplifier 10 such as audio frequency amplifier that is connected on the transducer by conductor 28.
Fig. 2 a and 2b are the local typical cutaway views of the loud speaker 81 of Fig. 1.Fig. 2 a has shown that framework 1, surround 3 and screen board 2 cemented joint 20 by separately links together.The suitable frame material comprises lightweight frame, for example by the frame frame of making such as the extrusion metal or the plastics of aluminium alloy.Suitable comprise elastomeric material such as foam rubber and foamed plastics around material.The viscose glue of suitable joint 20 comprises viscose glues such as epoxy, polypropylene and cyanogen propylene.
Fig. 2 b has illustrated that on the ratio of amplifying screen board 2 is rigidity light screen boards that have such as the made sandwich layer 22 of rigidity plastics foam 97, this rigidity plastics foam for example is the porous matrix 98 that interlinkage polyvinyl chloride or metal forming, plastics or analog are made, its hole extends transverse to the screen board plane, and by being enclosed such as the top layer 21 of the made opposition of paper, card, plastics or metal forming or thin plate.When its mesexine is made of plastics, can strengthen to improve their modulus in a kind of mode of knowing by using such as carbon, glass, kevlar (RTM) or similar fiber.
Disclosed skin-material and reinforce comprise paper, bonding ply of paper, melamine glue and such as polyester film, kapton, polyvinyl chloride, phenol, polyester or relevant plastics, fibre reinforced plastics etc. and sheet metal or paper tinsel, comprise that again carbon, glass, kevlar (RTM), Nomex (RTM) are the fiber of various twisting thread (lays) such as aromatic polyamide and textile-like.Investigation to the Vectra level of liquid crystal polymer thermoplastic shows that they are useful for injection moulding such as the ultra-thin property top layer below the diameter 30cm or the top layer of smaller szie.This material self has formed the crystal structure of an orientation on the direction of spraying, this orientation is that high-frequency energy is propagated into screen board preferential direction on every side well from drive point.
Disclosed core material had both comprised foamed plastic or foamed plastics or paper pulp material, suitable even low-density aerosol metal, the cellular or corrugated aluminium alloy sheet or the paper tinsel that comprise manufacturing again, or Kevlar (RTM), Nomex (RTM), common or bonding paper, and various synthetic plastic films.Some suitable core materials have been showed its spontaneous top layer useful in its manufacture process effectively and/or have been had natural enough intensity to be used to not have the top layer interlayer of laminate patch.Known a kind of high performance its trade mark of cellular core material is called ' Rohacell ', and it can be used as the radiation screen board and does not have the top layer.From the aspect of reality, its objective is that acquisition is suitable for the fineness and the intensity of the integral body of special purposes, comprise that particularly the best of core and top layer layer is formed and the conduction between them.
Suspension 3 can damping screen board 2 the edge in case the too much border movement of this screen board.In addition or replacedly adopt other damping, such as wiring, can be connected to that the too much motion of damping is come in the position of choosing in the screen board so that the even distribution of resonance on screen board.This wiring can be that asphalt-based material is made, and as employed in common loudspeaker housing, perhaps can be made by elasticity or rigidity polymerization light sheet material.Some materials, particularly paper and card and some cores can self-dampings.If desired, can non-rigid assembling viscose glue increases damping in the mechanism of screen board by using elasticity assembling viscose glue.
Effectively describedly select damping to comprise special application to the light sheet material of screen board and permanent connected device.Edge and angle are significant especially to low frequency modes main and its screen board dispensed in small quantity.The edge of damping device is fixed with to be beneficial to and produces the screen board that its described light sheet material installs framework fully, although its angle may be often relatively free, such as for the required stretching, extension of low frequency operation.Attachment can be with viscose glue or self adhesive material.The damping form that other is useful aspect meticulousr effect and/or intermediate frequency and high frequency, can or be secured to the material of being scheduled in the above zone of light sheet material on the effectively central local location by suitable material especially.
It is two-way resembling top illustrated sound-screen plate.The acoustic energy that sends from behind is not in very strong phase place with respect to the acoustic energy that sends previously.The result be help that acoustical power whole in this room add up, the minimizing of distribution, reflection and the standing wave effect of equifrequent acoustic energy and help that high-quality ground reproduces place and environment in the acoustical reproduction record.
Although the radiation of sending from the sound-screen plate mainly is unoriented, the percentage axle of the phase place relevant with information increases outward.Because the focus after the improvement of imaginary stereo image, the orientation of loud speaker are the same with picture, on the height when usually the people is upright, thereby provide the axle exterior orientation of favourable appropriateness, the stereoeffect of the best is provided for the audience who is seated usually.Equally, a triangle left side/right geometric figure with respect to the audience provides another angle component.The good stereo acquisition that comes to this.
Compare with common loudspeaker reproduction, the present invention also has the advantage at a group audience.The inherent propagation characteristic of sound-screen plate acoustic radiating has given its volume of not observing the square distance law of reciprocity of identical point source.Because the intensity that reduces with distance is much smaller than the intensity of being predicted by inverse square law, the result is for off-center and the bad hearer in position, and the screen board loud speaker is compared its intensity field with common loud speaker and promoted a better stereophonic effect.This is because off-centered hearer can't suffer dual problem owing near the loud speaker approaching: at first near the loudness of loud speaker increases greatly, and the loudness of loud speaker far away then is corresponding to be reduced.
Screen board formula loud speaker flat, lightweight also has advantage, and it is visually attractive, has good sound quality and only needs a transducer and the gamut sound that sends from each screen board film does not have overlapping.
Fig. 3 shows greeting card or its similar card that the Supreme Being has Fig. 1 and loud speaker technology shown in Figure 2.Page or leaf 145 was with back page or leaf 146 and can fold mutually before jig had.At least thereafter page or leaf 146 is to make with composite plate, and this composite plate comprises the foamed plastics sandwich layer 22 that is clipped between the Handicraft decorative plate 21, to form one as Fig. 1 and this class rigidity light distributed acoustic radiator screen board 2 shown in Figure 2.Fortune class composite plate has known that its trade name is KAPPABOARD.The screen board of also finding simultaneously the shaping of conform European standard (EuropeanStandard) " A " series is suitable.
Also should be noted that, in this structure is provided with, do not need framework 1 or periphery 3.The material that becomes by blocking and/or grip this card or it is stood up on a plane and just can provide enough big damping action.
Fig. 4 has shown a kind of transducer 9 that is used for distributed screen board 2, and its form is the crystal dish formula piezo flexure 27 that is contained on the dish 118 of brass for example, and dish 118 connects 20 by bonding agent and is fixed on the surface of screen board 2.During work, by lead 28 acoustical signal is added to and causes 27 bendings of piezoelectricity dish on the transducer 9, and make screen board 2 strain partly, thereby bending wave is transmitted in the screen board.
