A kind of embodiment, can arrange acoustical cotton (not shown in figure 1) in woofer case shell 20 inside, strengthens the acoustical quality of woofer;
A kind of embodiment, needs to arrange the acoustical quality that paraphase hole (not shown in figure 1) strengthens woofer on the woofer case shell 20 except interface surface 201 according to actual design.
Another embodiment, can also arrange reinforcement on woofer case shell 20, to strengthen the firm intensive properties of woofer case shell, prevents resonance, improves the durability of woofer case shell 20.
Owing to there is no circuit element in the inside of woofer case shell 20, thus the restriction of space structure aspect only can be considered to the design of woofer case shell 20, woofer case shell 20 is made arbitrary shape and thickness, to adapt to the headspace of the corresponding type of panel TV to greatest extent, ensure woofer acoustical quality.
As shown in Fig. 2 (a)-(c), same woofer main body 10 can the woofer case shell 20 of adaptive multiple difformity and thickness, thus enhance the versatility of woofer main body 10, shorten the construction cycle of woofer entirety, reduce components and parts cost.
Further, in order to strengthen the versatility of woofer case shell 20, woofer case shell 20 can also be sealed by plural case shell unit and be spliced (there is encapsulant junction, ensures air tight), to strengthen the versatility of case shell further.As shown in Figure 3, woofer case shell in Fig. 2 (b) is sealed splicing by the case shell unit (b1, b2, b3) of several general minor structure complete, similar splicing building blocks are the same, like this when needing larger case shell-space, just can be spliced by the case shell unit of these minor structures.
The woofer of the embodiment of the present invention, by woofer being divided into woofer main body 10 and woofer case shell 20 two parts, on the one hand because woofer case shell 20 inside does not have circuit element, facilitate the shape of woofer case shell and the design of thickness, adapt to the headspace of the corresponding type of panel TV to greatest extent, thus ensure that woofer acoustical quality, on the other hand because same woofer main body can the woofer case shell of adaptive multiple difformity and thickness, thus enhance the versatility of woofer.
It should be noted that, the current needs in order to adapt to ultrathin flat television set type, needing must be as far as possible thin by the Thickness Design of woofer main body 10, such as, be designed to the thickness of 15mm or 13mm or thinner.Common way is, after the thickness of woofer main body 10 reaches requirement (such as 15mm or 13mm), change no longer easily, this is because once woofer main body 10 thickness changes, the structure needed the loudspeaker unit 101 that it comprises is redesigned, have all circuit elements of woofer owing to assembling in loudspeaker unit 101, the change of its structure will increase the debugging difficulty of circuit element in loudspeaker unit 101.
In addition, in order to strengthen the versatility of woofer main body 10, also must consider that the woofer case shell 20 matched wraps up the volume of air, this bulking value can in a floating scope, within such as 50%.Illustrate, the woofer main body of a 13mm thickness, woofer case shell optimal volume adaptive with it may be 0.6L, but the volume between 0.3L to 1.2L, its acoustical quality is also fine.Therefore to arbitrary money woofer main body, in order under the prerequisite ensureing acoustical quality, strengthen the generalization degree of woofer, also must consider the volume of the woofer case shell that multiple panel TV types adaptive with it can allow.
The panel TV of a kind of built-in woofer that the embodiment of the present invention provides, described built-in woofer comprises the technical characteristic of the invention described above embodiment woofer.In use, first woofer main body and woofer case shell two parts can be spliced to form a woofer entirety, and then be built in panel TV as the woofer of existing integral type.
Embodiment one, for 42 cun, 47 cun and 55 cun of these three kinds of panel TV types, by shape-designing requirement, is respectively 20mm, 25mm and 30mm from screen to the distance of back cover.If mentality of designing traditionally, the woofer (increasing development time and components and parts cost) of design three kinds of different-thickness, entirely design woofer (47 cun and 55 cun of general woofers of 42 cun by the thickness of 42 cun, but the inner space of 47 cun and 55 cun types does not make full use of, bass effect can only reach the level of 42 cun).If but adopt mentality of designing of the present invention, then can design the case shell of general woofer main body that a thickness is 15mm (having considered the gap of woofer main body and screen and back cover) and three different-thickness.42 cun of type case thickness of the shell 15mm, 47 cun of type case thickness of the shell 20mm, 55 cun of type case thickness of the shell 25mm.Because 55 cun of type case shell-spaces are maximum, its bass effect is best, and 47 cun of bass effects take second place, and the bass effect of 42 cun is relatively more weak (but the casing internal space of 42 cun takes full advantage of, and does not regret in design).Therefore, the embodiment of the present invention can better meet product design needs, realizes the product orientation of different panel TV.
Embodiment two, see accompanying drawing 4-6, the forward and backward shell of certain panel TV of 42 cun, needs general A, B, C tri-kinds screen.Nut column 300 positions on three kinds of screens are different, and wiring board 400 (as LED drive board, the T-con plate etc.) size that screen carries, position are also different.
Accompanying drawing 4-6 is the dorsal view of flat television complete machine, other critical pieces on screen: mainboard, power panel, main sound channel loud speaker 500 can comparatively be easy to accomplish general, built-in woofer only, are difficult to general, reason is, (A) see in accompanying drawing 4-6:
1) A screen is common LED screen, and the structure of screen is comparatively regular;
2) B screen is LED screen with 3D function, how one piece of wiring board iii on screen, and the position of wiring board i with ii and size are also shielded different from A, bring difficulty to built-in woofer generalization;
3) C screen is common LED screen, but screen on the wiring board ii left side many 2 protruding posts 350, woofer cannot be placed by protruding post 350 place;
4) because back cover requires general, back cover can hold sound mouth in the position of woofer loudspeaker unit, but due to the reason such as structural strength, aesthetics, sound mouth can only be opened in a fixing region, also namely for these three kinds screens, woofer unit relative position can not become.
If adopt traditional mentality of designing, designing the built-in woofer of a general above-mentioned three kinds of screens, is almost impossible.But adopt mentality of designing of the present invention, see (D) in accompanying drawing 4-5, can a general woofer main body 600, join 4 woofer case shells (a, b, c, d) in addition.Can splice between its raising middle flask shell c and case shell d, the common C of adaptation shields.Certainly, case shell c and case shell d is made an overall case shell, is also fine.It can thus be appreciated that the embodiment of the present invention can better meet product design needs, ensure that the volume of woofer, achieve the doulbe-sides' victory of generalization and good tonequality.
Above-mentioned specific embodiment is not in order to limit the present invention; for those skilled in the art; under the premise without departing from the principles of the invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
