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 insulating bushing of an electret condenser microphone is disposed on the rear side of a back electrode portion and abuts against the rear surface of back electrode plate. When a predetermined force is applied to the insulating bushing from the opened end of the case by way of a fixing ring and a printed circuit board, the insulating bushing deforms so as to fit into a gap formed between the inner peripheral face of the case and an end portion of the back electrode plate. Since the insulating bushing fits between the inner peripheral face of the case and the end portion of the back electrode plate, the back electrode plate is positioned and fixed with respect to the case in a state where the back electrode plate and the case are electrically insulated from each other.
