Therefore, be necessary to provide a kind of novel acoustical generator to solve the problems referred to above.
[utility model content]
The purpose of this utility model is to provide a kind of acoustical generator that strengthens the intensity of upper cover.
The technical solution of the utility model is as follows: a kind of acoustical generator, it comprises upper cover, be provided with the acoustical generator monomer of magnetic bowl and vibrating diaphragm, lower cover and the basin frame between upper cover and lower cover, the common winding of described upper cover, basin frame and lower cover forms the spatial accommodation of accommodating the acoustical generator monomer, described upper cover comprises the plastic stent of metallic plate and fixed metal plate, the madial wall that described metallic plate is provided with some through holes and forms described through hole, madial wall from through hole extends flange, described flange is embedded in described plastic stent, and described plastic stent covers through hole fully.
Preferably, described flange is that madial wall from through hole is to extended away from the direction of described acoustical generator monomer.
Preferably, described through hole is arranged in a row, and is positioned at a side of metallic plate, and plastic stent is provided with the corresponding lug boss that covers all through holes.
Preferably, the periphery of described metallic plate also is provided with the kink that bending is extended, and described kink is embedded in described plastic stent.
Preferably, described plastic stent and metallic plate are that mode by injection mo(u)lding combines.
Preferably, described magnetic bowl is provided with a bowl wall, and described bowl wall is provided with breach, and described basin has set up inner surface, and described basin sets up the locating piece that protrudes out to spatial accommodation from inner surface, and described locating piece is placed in breach.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1 to Figure 3, be acoustical generator 100 of the present utility model, it comprises upper cover 10, acoustical generator monomer 20, lower cover 40 and the basin frame 30 between upper cover 10 and lower cover 40, and the common winding of described upper cover 10, basin frame 30 and lower cover 40 forms the spatial accommodation 31 of accommodating acoustical generator monomer 20.
In the utility model acoustical generator 100, in order to strengthen the intensity of upper cover 10, upper cover 10 comprises the plastic stent 11 of metallic plate 12 and fixed metal plate 12, and metallic plate 12 combines with the mode of plastic stent 11 by injection mo(u)lding.One side of metallic plate 12 is provided with the some through holes 121 that are arranged in a row, and plastic stent 11 is provided with the corresponding lug boss 110 that covers all through holes 121, has reduced thus the risk of gas leakage.In other embodiments, the shape of through hole 121, size, number, arrangement mode etc. do not limit.In addition, the madial wall that metallic plate 12 forms through hole 121 is provided with the flange 1210 that extends to away from the direction of acoustical generator monomer 20, and described flange 1210 is embedded in plastic stent 11.Thus, strengthen combination degree between plastic stent 11 and metallic plate 12, prevented that metallic plate 12 and plastic stent 11 from peeling off, also can not cause resonance during vibrating diaphragm 200 vibration, finally improved the intensity of upper cover 10.Wherein, flange 1210 can be the circulus around through hole 121, also can be just around the part of through hole 121.In other embodiments, flange also can extend downwards and be embedded in plastic stent, so just can save lug boss.For the intensity of further upper cover, the periphery of metallic plate 12 also is provided with the kink 122 that extends towards the bending of oblique below, and kink 122 is embedded in plastic stent 11.
In above-mentioned utility model acoustical generator 100, described magnetic bowl 26 is provided with bowl wall 260, is provided with breach 261 between adjacent bowl wall 260, and from the locating piece 32 that the inner surface of basin frame 30 protrudes out to spatial accommodation 31, described locating piece 32 is placed in breach 260.This kind structure can strengthen the location of magnetic bowl 26 and basin frame 30.In addition, the sidewall 33 of basin frame 30 is provided with sound hole 34, and the bearing of trend in sound hole 34 makes acoustical generator 100 side sounding thus perpendicular to the direction of vibration of vibrating diaphragm 200, so just can reserve more space to mobile phone screen.
