    • The present invention discloses a portable Karaoke system. The portable Karaoke system has a separate radio auxiliary microphone receiving module and a separate FM transmission module, which can be inserted/separated into/from the portable Karaoke system, such that a user can select and purchase only a required function module and easily carry and keep the portable Karaoke system. The portable system has hooks, which are provided at both sides of a battery case to prevent a battery from being easily separated from the battery case, and semicircular recesses, which are formed at the top edges of both sidewalls of the battery case to allow a user to easily remove the battery from the battery case. Furthermore, the portable Karaoke system has first and second gears formed at stepped portions of the end of a microphone body such that the first gear is combined with a general microphone net and the second gear is combined with a ball-type microphone net.
    • 本发明公开了一种便携式卡拉OK系统。 便携式卡拉OK系统具有单独的无线电辅助麦克风接收模块和独立的FM传输模块,其可以从便携式卡拉OK系统插入/分离,使得用户只能选择和购买所需的功能模块并且容易携带和 保持便携式卡拉OK系统。 便携式系统具有钩子,其设置在电池壳体的两侧以防止电池容易地从电池壳体分离;以及半圆形凹部,其形成在电池壳体的两个侧壁的顶部边缘处,以允许 用户可以轻松地从电池盒中取出电池。 此外,便携式卡拉OK系统具有形成在麦克风主体的端部的阶梯部分的第一和第二齿轮,使得第一齿轮与通用麦克风网络组合,并且第二齿轮与球型麦克风网络组合。
