Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1-2, the utility model provides a kind of microphone device 100, including frame 1, is fixed on the frame 1
Vibrational system 2 and magnetic circuit system 3, and the leakage structure 4 through the setting of the frame 1.The frame 1, the vibrational system 2
Confined space is surrounded jointly with the magnetic circuit system 3.
The frame 1 is surrounded by side wall 10, the leakage structure 4 through the side wall 10 be arranged and with the confined space
Connection, for balancing 100 inside of the microphone device and external sound pressure equalisation.
Specifically, the frame 1 is in rectangular configuration, the side wall 10 includes two the first side walls 11 being oppositely arranged and phase
To two second sidewalls 12 of setting, the first side wall 11 and the second sidewall 12 surround the frame 1 jointly, and described
The length of one side wall 11 is more than the length of second wall 12.In present embodiment, the leakage structure 4 runs through the second side
Wall 12 is arranged, that is, is set on the shorter side wall of the frame 1.Certainly, the structure of the frame 1 is not limited to rectangle.
The vibrational system 2 includes the vibrating diaphragm 21 for being fixed on the frame 1 and the sound for driving 21 vibration sounding of vibrating diaphragm
