Abstract
The invention discloses a novel receiver comprising a sounding unit. The sounding unit comprises an armature and an iron core. The armature is a U-shaped reed which comprises a connecting portion, a bending portion, and a vibrating portion which are connected successively. The iron core is sleeved on the vibrating portion and close to an opening of the reed. In addition, the iron core is soldered on the inner surface of the connecting portion in a surface soldering manner and forms a connecting surface on the connecting portion. The width of the connecting portion is gradually increased from the bending portion to the opening. According to the novel receiver, soldering area is greatly increased and the combination degree of the armature and the iron core is improved. Therefore, the armature and the iron core are not liable to loosen in the operation of the receiver. Thus, the integral intensity of the sounding unit is further enhanced and the service life of the receiver is prolonged.

Further, the electrode tip material that described welding adopts is beryllium copper.
Further, described phonation unit also comprises magnet, coil, conductive bar and vibrating diaphragm; Described magnet is covered on the inner surface of described iron core, and described coil is sheathed on described vibration section and near described bending part, the two ends of described conductive bar be in transmission connection respectively described vibrating diaphragm and described vibration section.
Further, described conductive bar is guide pin.
Further, described receiver also comprises screening can, and described phonation unit is arranged at wherein.
Further, inner relative two walls of described screening can are provided with step surface, and described vibrating diaphragm is arranged on described step surface.
Further, described vibrating diaphragm is divided into ante-chamber and back cavity by the inner chamber of described screening can, is provided with the vocal hole of connection on the shell wall of described ante-chamber, is provided with the pore for strengthening low frequency output on the shell wall of described back cavity.
Further, the end of described vibration section is provided with the extension for being connected with described guide pin, on described extension, offers through hole, and described guide pin is arranged in described through hole.
Adopt technique scheme, the beneficial effect of technical solution of the present invention is: armature and the welding of iron core employing face, overcome the shortcoming of spot welding, bonding area increases greatly, both conjugations have been improved, make receiver in use armature and iron core be difficult for looseningly, further increased the bulk strength of phonation unit, extended the useful life of receiver.
