Direction of vibration on abut the magnet frame.
The utility model sets notch, the convex block extension by setting convex block in the frame on the side wall
To the notch and the magnet frame is abutted, frame and magnet frame strong fix；It is described since the material of the frame is magnetic conductive metal
After convex block is embedded in the notch, the magnetic property that the magnet frame is lacked in the barbed portion is compensate for, ensures the magnet frame
Magnetic property do not lose, the vocal performance of the microphone device is good.
In addition, the frame, which is additionally provided with the direction of vibration perpendicular to the vibrational system, abuts the convex of the side wall
Rise, ensure the magnet frame and positioning of the frame on the direction of vibration perpendicular to the vibrational system.
In addition, glue is filled in gap between the frame and the side wall fixes the frame and the magnet frame, carry
Bond strength between the high frame and the magnet frame.
In addition, the side wall includes a pair of of the short side wall being oppositely arranged and a pair of of the long side wall being oppositely arranged, the notch
It is arranged at the centre position of the pair of short side wall or/and the pair of long side wall.
In addition, the side wall includes a pair of of the short side wall being oppositely arranged and a pair of of the long side wall being oppositely arranged, it is the pair of
Short side wall and the pair of long side wall are abutted with the protrusion respectively.
In addition, the magnetic conductive metal material is carbon steel.
