Below in conjunction with drawings and embodiments, the invention will be further described.
Please join simultaneously shown in Fig. 1-3, the present invention provides a kind of microphone device 100, including frame 1, is fixedly supported to respectively
The vibrational system 2 and magnetic circuit system 3 of the frame 1, the protecgulum 4 and fixed column 5 for being fixed on the frame 1.
The frame 1 is made of metal material comprising side wall 11 and the card hole 12 being arranged through the side wall 11.Metal
The frame 1 of material may act as a part for magnetic circuit system 3 for keeping off magnetic, the performance of magnetic circuit system 3 is effectively improved, to make
The acoustical behavior for obtaining microphone device 100 is more excellent.
In present embodiment, by the frame 1 be rectangular configuration for illustrate, i.e., the described side wall 11 include four and
The frame 1 is surrounded jointly, and the card hole 12 includes at least two and spaced setting.Card hole 12 described in present embodiment
Including four and be located at the frame 1 four angles position.
Certainly, the quantity of the structure of the frame 1 and the card hole 12 is not limited to this, for example, the frame 1 is alternatively
The quantity of circle etc., the card hole 12 can be spaced set, this is all feasible.
The vibrational system 2 includes the sound that support is fixed on the vibrating diaphragm 21 of the frame 1 and the vibrating diaphragm 21 is driven to vibrate
Circle 22.
Electromagnetic field is collectively formed with the magnetic circuit system 3 in the vibrational system 2, drives 2 vibration sounding of the vibrational system.
The pressure of the protecgulum 4 is set on the vibrating diaphragm 21 and is fixed on the frame 1.The protecgulum is equipped with through speaking thereon
Hole 41 and it is recessed the card slot 42 formed by laterally closer 21 direction of the vibrating diaphragm of its one far from the vibrating diaphragm 21.
It is described go out acoustic aperture 41 be oppositely arranged with the vibrating diaphragm 21, for speaking.More preferably, it is described go out acoustic aperture 41 shake with described
21 face of film is arranged.
The fixed column 5 is fixed on the frame 1 and is extended by the frame 1 described for the protecgulum 4 to be fixed on
Frame 1.
The fixed column 5 includes at least two and spaced setting.For example, the fixed column 5 is arranged at equal intervals.This reality
It applies in mode, the fixed column 5 is integrated injection molding with the frame 1.By the part, injection molding manner makes metal material
The frame 1 forms the fixed column 5 of the fixed protecgulum 4.
