    • An accessory device having a first and second body is described. The second body may include a force feedback mechanism that responds to an input received at the first body causing a force feedback. The force feedback mechanism includes coils distributed throughout the second body, with each coil configured to receive an electrical current such that each coil provides an external magnetic field to magnetically couple with one or more magnets disposed in the first body, causing the first body to move in a direction toward the second body. The first body may return to its original position when the external magnetic field is no longer applied. In this regard, the movement of the first body defines the force feedback. Also, the first body may include a keyboard or a touch screen functioning with the force feedback mechanism. The accessory device may be used in conjunction with an electronic device.
    • 描述具有第一和第二主体的附件装置。 第二主体可以包括力反馈机构,其响应于在第一主体处接收的输入引起力反馈。 力反馈机构包括分布在整个第二主体中的线圈,其中每个线圈被配置成接收电流,使得每个线圈提供外部磁场以与布置在第一主体中的一个或多个磁体磁耦合,从而使第一主体移动 朝向第二身体的方向。 当不再施加外部磁场时,第一机体可能返回到其原始位置。 在这方面,第一体的运动定义力反馈。 此外,第一主体可以包括与力反馈机构一起工作的键盘或触摸屏。 附件装置可以与电子装置结合使用。
