[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As Figure 1-3, a kind of microphone device 10, it comprises basin frame 1, is fixed on vibrational system 2 and magnetic circuit system 3 on basin frame 1.Vibrational system 2 comprises vibrating diaphragm 21 and drives the voice coil loudspeaker voice coil 22 of vibrating diaphragm 21 vibrations; Magnetic circuit system 3 bags are fixed on the magnetic bowl 31 on basin frame 1.Magnetic bowl 31 comprises diapire 311 and grows limits vertically extending long sidewalls 312 respectively by two of diapire 311.That is to say that the utility model microphone device 10 is rectangle.Wherein, magnetic bowl 31 also comprises by two of diapire 311 grows limits respectively to the extended buffer part 3111 of direction near basin frame 1, buffer part 3111 butt basin framves 1, and buffer part 3111 and long sidewall 312 be not at same plane.In present embodiment, buffer part 3111 is positioned at same plane with diapire 311, and this structure makes buffer part 3111 can bear to greatest extent the impact of external force.Certainly, buffer part 3111 also can be at same plane with diapire 311, and namely buffer part 3111 is extended to form by diapire 311 bendings, and buffer part 3111 is not positioned at same plane with long sidewall 312, and this is also feasible, but principle all.
The utility model microphone device 10 arranges respectively buffer part 3111 because of two long limits at the diapire 311 of magnetic bowl 31, and buffer part 3111 butt basin framves 1.When the long side (not label) of the long axis direction of basin frame 1 when being subject to external impact force, 3111 of buffer part are equivalent to strengthen the intensity of the long side on the long axis direction of basin frame 1, most of impulsive force that basin frame long side is subject to cushions and is transferred to the diapire 311 of magnetic bowl 31, thereby the impulsive force that the long sidewall 312 that makes magnetic bowl 31 is subject to greatly reduces, avoid long sidewall 312 even to come off because of the time distortion of being hit, strengthened the impact resistance of microphone device 10.And then improved the unfailing performance of microphone device 10.In present embodiment, buffer part 3111 lays respectively at the centre position on two long limits of diapire 311, and this structure makes the power that withstands shocks that buffer part 3111 can more effective more balance.
In the utility model microphone device 10, magnetic bowl 31 be included in also that the end positions of long sidewall 312 arranges respectively by the extended auxiliary buffer part 3112 of diapire 311, auxiliary buffer part 3112 butt basin framves 1.Certainly, the setting of auxiliary buffer part 3112 is the basin frame 1 suffered impulsive force of long axis direction side in order to cushion microphone device 10 too.
The centre position of long sidewall 312 also is provided with notch part 3121, and the inboard of basin frame 1 also is provided with the resettlement section 11 of the long sidewall 312 of accommodating magnetic bowl 31, and resettlement section 11 is provided with the limiting section 111 that protrudes to magnetic bowl 31 directions, and limiting section 111 is fastened in notch part 3121.The cooperation of notch part 3121 and limiting section 111 makes basin frame 1 and magnetic bowl 31 fix more firmly, and basin frame 1 and magnetic bowl 31 can accurately be fixed.
Compare with correlation technique, the utility model microphone device is provided with buffer part and butt basin frame on the long axis direction of the diapire of magnetic bowl, thereby the impulsive force that basin frame long axis direction is subject to is cushioned and transfer to magnetic bowl wall, avoided the long sidewall of magnetic bowl because being subjected to external impacts be out of shape or come off.Strengthen the anti-impact force of microphone device long axis direction, improved the reliability of microphone device.Particularly for the larger microphone device of Aspect Ratio, this reliability more remarkable effect.
Above-described is only execution mode of the present 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 protection range of the present utility model.
