With reference to the Fig. 1 in the accompanying drawing, shown the illustrated and panel type loudspeaker 81 that requires in our international application no (our case number for P.5711) of common pending trial of same period therewith, it comprises the rectangular frame 1 that has spring suspension 3, and described suspension centers in it and supporting a distributed acoustic radiant panel 2 week.Such as transducer 9 with reference to detailed description in our international application no (our case number be P.56831415) of pending trial of same period therewith, intactly and exclusively be installed on the panel 2 or preset bearing that wherein limits by x and y, the calculating that illustrates in our international application no (our case number be P.5711) of pending trial of the position in its orientation by same period therewith, in panel, make panel resonance come radiation output with the emission flexural wave.
Fig. 2 a and 2b are the local typical cut-open views of the loudspeaker 81 of Fig. 1.Fig. 2 a has shown that framework 1, surround 3 and panel 2 cemented joint 20 by separately links together.The suitable frame material comprises the light weight framework, for example by the frame frame of making such as the extrusion metal or the plastics of aluminium alloy.Suitable surround material comprises the resilient material such as scum rubber and polyfoam.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 panel 2 is rigidity lightweight panel that have such as the made core 22 of rigidity plastics foam 97, this rigidity plastics foam for example is the latticed matrix 98 that interlinkage Polyvinylchloride or metal forming, plastics or analog are made, its cell extends transverse to panel 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.
Top layer layer material and the reinforce that can look forward to comprises paper, bonding ply of paper, melamine glue and such as mylar, kapton, Polyvinylchloride, phenol, polyester or relevant plastics, fibre reinforced plastics etc. and sheet metal or paper tinsel, comprises 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 panel preferential direction on every side well from drive point.
Additional this and injection moulding other thermoplastic makes injection mold have location and alignment feature such as groove or ring, in order to the transducer element of accurate location such as motor coil and magnet suspension.Some additional more weak core material it is calculated that and help increasing such as local skin depth in 150% zone that reaches transducer diameter or the annular, strengthen that piece zone and help energy of vibration is coupled in the panel.The high-frequency response will be improved with softer foamed material by this device.
The core material that can look forward to had both comprised foamed plastic or polyfoam or paper pulp material, even if suitable low-density aerosol metal, comprise the latticed of manufacturing or corrugated aluminium alloy sheet or paper tinsel again, or Kevlar (RTM), Nomex (RTM), common or bonding paper, and various synthetic plastic films.Some suitable core materials have been showed the spontaneous top layer that it is useful effectively and/or have been had natural enough intensity to be used to not have the top layer interlayer of laminate patch in its manufacture process.Known a kind of high performance its trade mark of latticed core material is called ' Rohacell ', and it can be used as radiant panel and does not have the top layer.From the aspect of reality, its objective is the comprehensive smooth finish and the intensity that obtain to be suitable for special purposes, particularly comprise the optimal components of core and top layer layer and the conduction between them.
Some optimization formulas that are used for panel use metal and metal alloy top layer, maybe can be for being the carbon fiber reinforce.All these, and the design of alloy gasoloid or wire netting trellis core, actual radio shielding feature all will be arranged, this feature is important in some EMC use.Common panel or cone loudspeaker do not have intrinsic EMC screening ability.
In addition, the preferred dynamic transducer of piezoelectricity has insignificant electromagnetic radiation or stray field.Common loudspeaker has a big magnetic field, if not adopt special compensation countermeasure will reach 1 meter distance.
The position that need to keep shielding in application can or can be used a kind of conductivity foam when the mounting edge or similar connector for electrical connector of conduction portion manufacturing of suitable DML panel.
The effectively described special application of selecting the light sheet material that damping comprises counter plate and permanent connected device.Edge and angle are significant especially to low frequency modes main and its panel dispensed in small quantity.Being fixed with along the limit of damping unit is beneficial to and produces the panel that its described light sheet material installs framework fully, although its angle may be often relatively free, such as for required low frequency operation.Connector 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 panel.The acoustic energy that sends does not from behind have very strong relation with the acoustic energy that sends previously on phase place.The result helps: acoustical power adds up in this room comprehensively, the propagation of equifrequent acoustic energy, reduced reflection and standing wave effect and helped that high-quality ground reproduces place and environment in the acoustical reproduction record.
Although the radiation of sending from the sound panel mainly is unoriented, the number percent axle of the information relevant with phase place increases outward.Because the focus after the improvement of imaginary stereoscopic image, the orientation of loudspeaker are the same with picture, on the height when usually the people is upright, thereby provide the axle outer 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 panel 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 panel loudspeaker is compared its intensity field with common loudspeaker and promoted a better stereophonic effect.This is because off-centered hearer can't suffer dual problem owing near the loudspeaker approaching; At first near the loudness of loudspeaker increases greatly, and the loudness of loudspeaker far away then is corresponding to be reduced.
Panel type loudspeaker flat, light weight also has advantage, and it is visually attractive, has good sound quality and only needs a transducer and do not have overlapping from the gamut sound that each panel membrane sends.
