Abstract
The utility model provides a sounder, which comprises an upper cover, an individual sounder body, a lower cover, and a basin bracket positioned between the upper cover and the lower cover. The upper cover, the basin bracket and the lower cover are assembled to form a space for accommodating the individual sounder body; the upper cover consists of a metal plate and a plastic bracket which surrounds the periphery of the metal plate to fix the metal plate; and the plastic bracket is fixed on the basin bracket. By adopting the scheme, the inner effective space of the sounder provided by the utility model is enlarged.
Description
[technical field]
The utility model relates to a kind of acoustical generator, relates in particular to a kind of ultrathin acoustical generator.
[background technology]
In the process of portable equipment fast developments such as mobile phone, people are more and more stronger to the functional requirement of product, for this function of Music Appreciation of mobile phone, in order to make entertainment effect stronger, the pattern that the music belt vibration occurred, thus, the also corresponding quickening of the development of acoustical generator.
The acoustical generator relevant with the utility model is provided with loam cake, acoustical generator monomer, lower cover and the basin frame between loam cake 40 and lower cover, the common winding of described loam cake, basin frame and lower cover forms the spatial accommodation of accommodating the acoustical generator monomer, described loam cake adopts plastic material, but loam cake need support certain intensity, therefore loam cake will be done to such an extent that thicklyer just can reach requirement, the space that has so just taken acoustical generator is many, cause the useful space of acoustical generator less relatively, reduced whole acoustical behavior.
Therefore, be necessary to provide a kind of novel acoustical generator to overcome the problems referred to above.
[utility model content]
The technical problem that the utility model need solve provides a kind of acoustical generator that can improve the inside useful space of product.
The technical solution of the utility model is as follows: a kind of acoustical generator, it comprises loam cake, acoustical generator monomer, lower cover and the basin frame between loam cake and lower cover, the common winding of described loam cake, basin frame and lower cover forms the spatial accommodation of accommodating the acoustical generator monomer, described loam cake comprises metallic plate and the plastic stent that centers on the fixed metal plate of described metallic plate periphery, and described plastic stent is fixed on the described basin frame.
Preferably, described plastic stent is provided with the first ring-shaped step portion of fixing described metal base plate.
Preferably, described metal base plate and described plastic stent are that mode by injection mo(u)lding combines.
Preferably, described basin sets up the second ring-shaped step portion of fixing described plastic stent.
Preferably, described loam cake and described basin frame are that mode by ultrasonic bonding combines.
Preferably, be covered with the first side wall under described, described the first side wall is provided with first breach, and described basin has set up second sidewall, and described second sidewall is provided with second breach, and described first breach communicates with described second breach.
Preferably, the thickness of described metallic plate is 0.1-0.2mm.
The beneficial effects of the utility model are: because loam cake comprises metallic plate and the plastic stent that centers on the fixed metal plate of described metallic plate periphery.Metal is harder than plastics, intensity good, so metallic plate can be done to such an extent that thinlyyer just can meet the requirements of intensity, so just can effectively save thickness space, has increased the useful space of acoustical generator.

Fig. 2 is the stereogram of the utility model acoustical generator;
Fig. 3 is the cutaway view along the A-A line shown in Figure 2.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, be the utility model acoustical generator 100, it comprises loam cake 10, acoustical generator monomer 20, lower cover 40 and the basin frame 30 between loam cake 10 and lower cover 40, and described loam cake 10, basin frame 30 and lower cover 40 common windings form the spatial accommodation 33 of accommodating acoustical generator monomer 20.
With reference to Fig. 2 and shown in Figure 3, lower cover 40 is provided with the first side wall 41 in the lump, and the first side wall 41 is provided with first breach 410, basin frame 30 is provided with second sidewall, 32, the second sidewalls 32 and is provided with second breach, 320, the first breach 410 and communicates with second breach 320, form leakage path, reach the purpose of balance acoustic pressure.
In the utility model acoustical generator 100, loam cake 10 is made of metallic plate 11 and plastic stent 12, improved the intensity of loam cake 10, only need the metallic plate of 0.1-0.2mm thickness just can reach the intensity of 0.5-1.2mm left and right sides plastic plate before, so just can effectively save thickness space, increase the useful space of acoustical generator.Such structure can also realize realizing ultrasonic bonding between loam cake 10 and the basin frame 30, has greatly improved the stability of producing line.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
