一种自动调节的麦克风
技术领域
本发明涉及一种扩音设备,尤其涉及一种自动调整方位的麦克风。 背景技术
麦克风分为有线麦克风和无线麦克风,它是会议和舞台上常用的 扩音装置, 一般是摆放在会议桌上或架设在舞台前。 由于有时需要多 人轮流或同时使用麦克风,或者需要根据不同的使用角度和不同的使 用高矮程度而进行适应性调节。
现有的麦克风一般是架设在可调整仰角和高矮的三脚架上,以根 据使用的需要由使用者来做出调整。 这种调整方式很不方便, 它需要 演讲人或表演人对麦克风做出经常的移动性操作、交换性操作或者变 换人体自身的位置, 不仅影响会议或表演的气氛、延误会议或表演的 时间、分散演讲人或表演人的精力,有时还会造成传递或调整中的失 误, 影响音响效果, 甚至 被拖在地面或空间的信号传输线所缠绊。
