Abstract
The invention discloses a bone-conducting receiver with an improved driving structure. The bone-conducting receiver comprises a housing, a vibrating diaphragm, an iron core, an armature, a guide probe, and a coil. The bottom end face of the iron core is fixedly connected with the vibrating diaphragm. A magnet is pasted on a through hole of the iron core. The side surface of the armature is in a U shape. By using a bending portion in the middle of the armature as an origin, one end of the armature is extended forwardly to the top end face of the iron core and forms a first connecting face at the top end face of the iron core. The first connecting face is fixedly connected with the top end face. Used as a vibrating portion, the other end of the armature is extended forwardly and passes through the through hole of the iron core. A part, exposed out of the iron core, of the other end of the armature forms a second connecting face. One end of the guide probe is connected with the inner wall of the housing, while the other end of the guide probe is connected with the second connecting surface. The coil is disposed between the bending portion and the iron core and is sleeved on the vibrating portion. The bone-conducting receiver has decreased integral volume and enhanced integral stability.

Guide pin, inwall, the other end that its one end is connected to described housing are connected to described the second joint face;
Coil, it is arranged between described kink and iron core portion 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 the second joint face.
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: the present invention 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 osteoacusis formula receiver, thereby expand its range of application; 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.
