Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further elaborated。
With reference to shown in Fig. 1 and Fig. 2, an embodiment of the present utility model is a kind of frame for speaker, including frame body 1, this frame body 1 includes the chassis 11 with centre bore 111, this chassis 11 is provided with in trumpet-shaped stake body, stake body also needs to be connected along 12 with ringwise front, what is more important, aforementioned brackets body includes the support chip 13 of multiple radially divergent shape, these support chips 13 are placed in chassis 11 and front along between 12, also arranging the venthole 14 of multiple radial direction in the side on chassis 11。Install on a speaker for ease of frame, also can in front along 12 multiple frame installing holes 18, then on chassis 11, be provided with multiple washer installing hole 19。
In the present embodiment, by the multiple support chips 13 in stake body are located at chassis 11 and front along between 12 in divergent shape, can not only ensure that frame has stronger resistance to compression and tensile strength on each Impact direction, and the total area of frame stake body can be greatly reduced, effectively reduce air resistance coefficient such that it is able to reach improve the electro-acoustic conversion efficiency of cone speaker and improve the effect of sound reproduction quality.
As mentioned here above, in frame open circles radially, its quantity is preferably arranged to 4 to 18 to the thickness of stake body, and the distance between adjacent supports sheet 13 it is preferably provided as equal；Being specially the size according to speaker frame opening is divided into 4.5 cun of frame to be 4 support chips 13,6.5 cun of frame are 5 support chips 13,8 cun of frame are 6 support chips 13,10 cun of frame are 8 support chips 13,12 cun of frame are 12 support chips 13,15 cun of frame are 13,18 cun of frame of 13 support chips be 13,21 cun of frame of 16 support chips is 18 support chips 13；Incomplete test according to inventor, the air resistance coefficient of the transverse section of above-mentioned stake body down wind is that K, K value is less than 0.65。
Preferably, one end of support chip 13 all extends in the middle part of the radial direction on chassis 11, and has the projection 2 axial relative to chassis 11, in order to and between speaker T ferrum 4 and washer 6, keep gap；
Further, install for ease of binding post bearing 17, also ring support 15 can be set up in above-mentioned stake body, this ring support 15 is installed on multiple support chip 13, and then can binding post bearing 17 be arranged on ring support 15, in addition, on aforementioned toroidal support 15, terminal mounting seat 16 is also set up again。
Going out as shown in Figure 2, in another embodiment of the present utility model, venthole 14, in order to further reduce the windage that stake body causes, also can be placed in the gap between support chip 13 by inventor；And outside support chip 13, the position corresponding with venthole 14 is respectively provided with meniscate recess 3；
With reference to shown in Fig. 3, another embodiment of the present utility model is the speaker of above-mentioned frame application, including T ferrum 4, this T ferrum 4 is provided with toroidal magnet 5, the top of toroidal magnet 5 is additionally provided with washer 6, and T ferrum 4 is provided with above-mentioned frame body 1, and make the centre bore 111 on the chassis 11 of frame body 1 corresponding with pole piece post through hole 41 position of T ferrum 4；Radially going back of T ferrum 4 has toroid gap between toroidal magnet 5, washer 6 simultaneously, is provided with voice coil loudspeaker voice coil 7 in toroid gap；Preferably washer 6 is connected with the chassis 11 of frame body 1 by washer installing hole 19；Described voice coil loudspeaker voice coil 7 is placed in the centre bore 111 on the chassis 11 of frame body 1。
Preferably, above-mentioned frame body adopts the materials such as fiberglass, aluminium alloy or plastics to be processed into, and moulding process adopts integrated mode, namely formed by the processes such as reverse mould, die casting, essence casting, injection moulding, there is bigger structural strength, in the selection of thickness, have bigger degree of freedom simultaneously, and be not magnetic conductor, in actually used process, magnetic Circuit Design will not be impacted by frame body 1, and practicality is stronger。
Wind-force backward is just created when the vibrating diaphragm of speaker promotes backward, the acoustic wave energy that this part wind-force is namely transformed by electric energy, from the energy indexing of speaker, the acoustic wave energy being transformed loses more few in the process propagated, then the transformation efficiency of cone speaker is more high。But the phenomenon that acoustic wave energy is destroyed by external object in the unavoidable existence of process propagated, this just requires that the stake body of frame body 1 has less wind resistance。Wind load according to " engineering mechanics " is theoretical, and object, under the effect of wind load, will produce three kinds of power: the resistance of down wind, transverse direction power, torsional moment。Frame simulate wind-tunnel measure in air-flow walk around frame be uniformly distributed radiation lamellar stake body model time, it is uniformly distributed radiation lamellar stake body to drag minimization produced by air-flow, this is that the air resistance coefficient K value owing to being uniformly distributed the transverse section radiating lamellar stake body down wind is less than 0.65, and at present on the market the air resistance coefficient K value of the transverse section of cone loudspeaker support body down wind all in 1.2, therefore frame is uniformly distributed the radiation lamellar stake body vibrating diaphragm drag minimization that produced sound wave air-flow produces backward to cone speaker, also just improve the efficiency of electroacoustic energy conversion, also the interference of sound wave is tailed off, and the accuracy of the sound wave improved and sound reproduction。
Than that described above, it can further be stated that " embodiment ", " another embodiment ", " embodiment " spoken of in this manual etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and include at least one embodiment that the application generality describes。Multiple local appearance statement of the same race is not necessarily refer to same embodiment in the description。Furthermore, it is understood that when describing a specific features, structure or feature in conjunction with any embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments。
Although reference be made herein to this utility model is described by multiple explanatory embodiment of the present utility model, but, should be appreciated that, those skilled in the art can be designed that a lot of other amendments and embodiment, and these amendments and embodiment will drop within spirit disclosed in the present application and spirit。More specifically, disclosure, drawings and claims scope in, it is possible to building block and/or layout to theme composite configuration carry out multiple modification and improvement。Except the modification that building block and/or layout are carried out and improvement, to those skilled in the art, other purposes also will be apparent from。
