Fig. 3 is the structure chart according to the microphone of the utility model one embodiment.
Embodiment
See also Fig. 1, Fig. 1 is the structural representation according to the vibrating diaphragm of the utility model one embodiment.As shown in Figure 1, the end face of vibrating diaphragm 100 is effective vibrating membrane 101, and the bottom surface of vibrating diaphragm 100 is a supporting surface 102, effectively has first foldable layer 103 and second foldable layer 104 between vibrating membrane 101 and the supporting surface 102.
Wherein, stepped setting between first foldable layer 103 and second foldable layer 104.And first foldable layer 103 is arranged between the effective vibrating membrane 101 and second foldable layer 104, and second foldable layer 104 is arranged between first foldable layer 103 and the supporting surface 102.
In other embodiment of the present utility model, the quantity of foldable layer can be more than two, and concrete quantity can be chosen according to actual needs.
Please further referring to Fig. 2, wherein Fig. 2 is according to the cross sectional representation of the vibrating diaphragm of the utility model one embodiment.As shown in Figure 2, vibrating diaphragm 100 is hollow halfpace shape, and, have a cavity 105 between vibration effective film 101, supporting surface 102, first foldable layer 103 and second foldable layer 104.
It should be noted that, in Fig. 1 and Fig. 2, vibrating diaphragm 100 illustrated be the circular hollow halfpace, but, in other embodiment of the present utility model, vibrating diaphragm 100 also can be any one in oval hollow halfpace, rectangle hollow halfpace, the square hollow halfpace or in the hollow stage of other shapes, and the utility model is not done concrete qualification to this.
See also Fig. 3, Fig. 3 is the structural representation according to the microphone of the utility model one embodiment.As shown in Figure 3, microphone 500 comprises substrate 300, backboard 200 and vibrating diaphragm 100, and wherein vibrating diaphragm 100 is the vibrating diaphragm that Fig. 1 and Fig. 2 introduced.And vibrating diaphragm 100 is arranged between substrate 300 and the backboard 200, and vibrating diaphragm 100 is fixed in the substrate 300 by supporting surface 102.
Insulation is provided with between vibrating diaphragm 100 and the backboard 200, and applies voltage respectively, makes vibrating diaphragm 100 and backboard 200 be equivalent to electric capacity (being that vibrating diaphragm 100 is two pole plates of electric capacity with backboard 200 difference equivalences).Hole 201 is set on backboard 200, when carrying out voice when picking up, sound wave imports into the cavity 400 from sound hole 201, vibrating diaphragm 100 is influenced by sound wave, produce vibration, thereby make the distance between backboard 200 and the vibrating diaphragm 100 change, and because vibrating diaphragm 100 and backboard 200 are equivalent to two pole plates of electric capacity respectively, and when the variable in distance between the pole plate of electric capacity, the capacitance of electric capacity can change, so when vibration takes place vibrating diaphragm 100, the voltage that can change between vibrating diaphragm 100 and the backboard 200, thus acoustic signals can be converted into the corresponding signal of telecommunication.
