Abstract: A bobbin unit includes a base portion and a coil winding portion on which a conductor is wound. A hole is formed in a central part of the base portion to allow an armature to pass through. Coil side terminals to which ends of the conductor are fixed and signal input terminals to which an external signal is entered are provided at opposite ends of the base portion with the hole located in between. The coil side terminals are electrically connected to their corresponding signal input terminals inside the base portion. A coil is formed on the coil winding portion by winding the conductor. The ends of the conductor are wound around the respective coil side terminals and fixed thereto by arc welding. Since the conductor is electrically connected to the signal input terminals when the ends of the conductor are fixed to the coil side terminals, connection of the ends of the conductor constituting the coil to the signal input terminals is made easy. Furthermore, the length of lead wire portions between the coil and the coil side terminals is shortened, making it possible to prevent breakage of the conductor between the coil and the coil side terminals.

Abstract translation: 线轴单元包括基部和缠绕导体的线圈绕组部分。 在基部的中央部形成有使电枢通过的孔。 固定导体的端部的线圈侧端子和输入外部信号的信号输入端子设置在基部的相对端，孔位于其间。 线圈侧端子与基座部分内部的对应的信号输入端子电连接。 通过缠绕导体在线圈绕组部分上形成线圈。 导体的端部缠绕在相应的线圈侧端子上并通过电弧焊固定。 由于当导体的端部固定到线圈侧端子时，导体电连接到信号输入端子，所以构成线圈的导体的端部与信号输入端子的连接变得容易。 此外，线圈和线圈侧端子之间的引线部分的长度被缩短，使得可以防止线圈和线圈侧端子之间的导体断裂。

Abstract: An electromagnetic receiver of a balanced armature type is employed as a receiver to be mounted in a portable telephone. The balance armature receiver has lower power consumption and higher electric acoustic conversion efficiency. The balanced armature receiver provides a required output even though small in size. The receiver occupies a considerably reduced space in the portable telephone, compared with a conventional portable telephone having a conventional dynamic receiver. The longitudinal wall of the receiver is parallel to the upper edge of a liquid crystal display panel, so that the liquid crystal display panel is extended upward and considerably enlarged.
