Description
[technical field]
The utility model relates to a kind of microphone device, relates in particular to a kind of microphone device that is used in the portable type electronic product field.
[background technology]
In recent years along with the fast development of mobile communication technology; The consumer uses the mobile communication equipment that has phonetic function more and more, for example portable phone, handheld device, laptop computer, palmtop computer, multimedia player and can be through other equipment public or that dedicated communications network communicates.And microphone device is as the playing device of voice, and its design quality directly influence is used the speech performance of the product of correlation technique microphone device.
The microphone device of correlation technique comprises vibrating diaphragm, supports the basin frame of said vibrating diaphragm, places the voice coil loudspeaker voice coil in the said basin frame and be fixed on the centring disk on the said vibrating diaphragm.
Yet; Its centring disk of the microphone device of correlation technique is spring leaf or FPC; Process because spring leaf or FPC are the very low material of metal or damping coefficient, send bad sound, also can produce bad sound reflecting simultaneously when said centring disk (spring leaf or FPC) is easy to produce resonance when vibrating with vibrating diaphragm; Thereby said microphone device is caused interference, and then influence the acoustical behavior of said microphone device.
Therefore, be necessary to provide a kind of new microphone device to address the above problem in fact.
[utility model content]
The technical problem that the utility model need solve provides the good microphone device of a kind of acoustical behavior.
According to above-mentioned technical problem, designed a kind of microphone device, its objective is such realization: a kind of microphone device, it comprises the basin frame, places the voice coil loudspeaker voice coil in the said basin frame, the centring disk that is fixed on the vibrating diaphragm on the said basin frame and is fixedly linked with said vibrating diaphragm.Wherein, be compounded with a layer damping material on the said centring disk.
Preferably, said damping material covers said centring disk fully.
Preferably, said centring disk comprises main part, bends the fixed part that extends by the elasticity arm of the reverse respectively bending extension in said main part two ends with by said elasticity arm, and said damping material is compounded on the said elasticity arm.
Preferably, said damping material is foam or damping glue or rubber.
Preferably; Said centring disk also comprises by the reverse respectively rib that extends in said main part two ends; Said rib is separated by a distance with said elasticity arm respectively, and said main part and said rib are fixed on the said vibrating diaphragm, and said fixed part is fixed on the said basin frame.
Preferably, the ring portion that said vibrating diaphragm is provided with the ball top and is fixedly linked with said ball top, the main part of said centring disk and rib are folded between said ball top and the said ring portion.
Compare with correlation technique, its acoustical behavior of the microphone device of the utility model is more excellent.

Fig. 2 is that Fig. 1 is along A-A line cut-away view.
Fig. 3 is the stereochemical structure exploded view of the utility model microphone device.
Fig. 4 is the centring disk stereogram of the utility model microphone device.
[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is described further.
Shown in Fig. 1-4, a kind of microphone device 10, it comprises basin frame 1, places the voice coil loudspeaker voice coil 2 in the basin frame 1, the centring disk 4 that is fixed on the vibrating diaphragm 3 on the basin frame 1 and is fixedly linked with vibrating diaphragm 3.Wherein, be compounded with damping material 5 on the centring disk 4.Centring disk 4 is spring leaf or FPC, and its damping coefficient is very low, when it vibrates along with vibrating diaphragm 3, is easy to produce resonance, thereby sends bad sound.And because have metal material on the centring disk, it also can produce microphone device 10 is caused dysgenic sound reflecting.Therefore, the utility model is composite damping material 5 on centring disk 4, the damping coefficient of centring disk 4 is increased, thereby alleviate its resonance amplitude, has reduced the generation of bad sound.Damping material 5 can absorb sound reflecting again simultaneously, has reduced metal material and has produced the intensity of sound reflecting, and then reduced the harmful effect that sound reflecting causes microphone device 10.
Concrete, on microphone device 10 its centring disks 4 of the utility model compound damping material 5 cover centring disk 4 fully.Damping material 5 is foam or damping glue or rubber.Certainly, damping material 5 also is not limited to this, can also be the big material of other damping coefficient, like dry goods etc.
As shown in Figure 4; The microphone device 10 of the utility model; Its centring disk 4 comprises main part 41, the elasticity arm 43 that extends by the respectively reverse rib 42 that extends in main part 41 two ends, by the reverse respectively bending in main part 41 two ends and the fixed part 44 that is extended by elasticity arm 43 bendings; Rib 42 is separated by a distance with elasticity arm 43 respectively, and main part 41 is fixed on the vibrating diaphragm 3 with rib 42, and fixed part 44 is fixed on the basin frame 1.So-called reverse the extension with reverse bending extended, and is such in this execution mode, and rib 42 extends by the two ends of main part 41 are reverse respectively, and rib has two in other words, and it is extended by main part 41 two ends respectively in the opposite direction; And elasticity arm 43 is to be extended by the reverse respectively bending in main part 41 two ends, and two elasticity arms 43 also have two in other words, and it by the two ends bending earlier of main part 41, extends respectively more in the opposite direction.Because the bending of elasticity arm 43 is extended, then make rib 42 separated by a distance with elasticity arm 43 respectively, thereby make the elasticity arm 43 can be unsettled.Rib 42 respectively with elasticity arm 43 rib and the elasticity arm standoff distances that are positioned at main part 41 same ends that in this execution mode, are meant separated by a distance.Certainly, the structure of centring disk 4 is not limited only to this.The ring portion 32 that microphone device 10 its vibrating diaphragms 3 of the utility model are provided with ball top 31 and are fixedly linked with ball top 31, the main part 41 of centring disk 4 and rib 42 are folded between ball top 31 and the ring portion 32.
The above-mentioned first kind of execution mode that is the utility model microphone device 10.
The utility model microphone device 10 also has second kind of execution mode, and it is identical substantially with first kind of execution mode, and different is that damping material 5 is not to cover said centring disk 4 fully, but only is compounded on the elasticity arm 43.Elasticity arm 43 is whole centring disk 4 elastic force the best parts, also is the major part that produces resonance and harmful sound reflecting, and therefore, composite damping material 5 on elasticity arm 43, also can reach the purpose of the utility model.
Compare with correlation technique; Be compounded with damping material on its centring disk of the microphone device of the utility model; This structure has increased the damping coefficient of centring disk; Alleviate even eliminated the resonance of centring disk and the sound reflecting harmful, and then improved the acoustical behavior of relative technological products microphone device.
Above-described only is the execution mode of the 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 the protection range of the utility model.
