A line control device of an earphone, comprising: an upper cover; a middle cover, the middle cover being detachably and fixedly connected to the upper cover, and an arranging space for arranging a control panel being enclosed between the upper cover and the middle cover; and a lower cover, the lower cover being fixedly connected to the middle cover, housings which surround the control panel and the middle cover being oppositely formed on the lower cover and the upper cover, shielding parts being formed on the edges at both sides of the middle cover, and the shielding parts being used for correspondingly closing the gaps between the opposite edges of the upper cover and the lower cover. The present invention can achieve multi-function control by using the structure; at the same time, it is convenient to disassemble and replace damaged parts and components in a simple snap-fitting manner, so that the costs are low; and at the same time, perspiration and dust can be prevented from entering the inside of a line control assembly via the shielding parts of the middle part, so that it is avoided that the function is influenced because the control panel is corroded. |
