    • The present disclosure provides a three-coil type round window driving vibrator, which includes a permanent magnet having the same magnetic poles adjoining each other and is designed to allow electric current flowing through coils to run in opposite directions in order to increase driving force without being affected by an external magnetic field. The round window driving vibrator includes a permanent magnet having three poles of SNS or NSN, a coil member wound around an outer periphery of the permanent magnet, and a vibration member connected to one end of the permanent magnet. Here, the coil member includes a first coil wound around a middle section of the permanent magnet and second and third coils wound around upper and lower sections of the permanent magnet, respectively.
    • 本公开提供一种三线圈式圆窗驱动振动器,其包括具有彼此相邻的相同磁极的永磁体,并且被设计成允许电流流过线圈以相反的方向运行,以便增加驱动力而不会 受外部磁场的影响。 圆窗驱动振动器包括具有SNS或NSN的三极的永磁体,缠绕在永磁体的外周的线圈构件和连接到永磁体的一端的振动构件。 这里,线圈构件包括缠绕在永磁体的中间部分的第一线圈和分别缠绕在永磁体的上部和下部的第二和第三线圈。
