Armature, its side takes the shape of the letter U, taking the kink in the middle of described armature as starting point, one end of described armature extends to forward the upper surface of described iron core and forms one first joint face at this place, described the first joint face is fixedly connected with described upper surface, the other end of described armature extends forward and passes the through hole of described iron core as vibration section, the part of exposing forward described iron core forms one second joint face;
Guide pin, its one end is connected to described vibrating diaphragm, the other end is connected to described the second joint face;
Coil, it is arranged between described kink and iron core and is sheathed on described vibration section.
Preferably, the first above-mentioned joint face starts width by described kink and becomes gradually large.
Preferably, the area of the first above-mentioned joint face is greater than the area at least 20% of described vibration section.
Preferably, the angle of above-mentioned kink is 90 degree, and R angle is less than 0.3mm.
Preferably, on the second above-mentioned joint face, be also provided with protuberance, described guide pin is connected on described protuberance.
Preferably, on above-mentioned protuberance, offer through hole, described guide pin wears in described through hole.
Preferably, above-mentioned guide pin forms a bending part through bending after described through hole.
Adopt the beneficial effect of above technical scheme to be: to the utlity model has improved U-shaped armature and new and the syndetons such as shell, iron core and coil, than prior art, it can dwindle the width of armature, and then the overall volume of dwindling receiver, thereby the range of application of expansion receiver; U-shaped armature can form the support more firm to vibration section, improves the stability of vibration section; U-shaped armature is directly directly connected with the form of joint face with iron core, and than spot welding, not only technique is simple, also can improve the reliability of connection.
