Abstract

本实用新型涉及一种教学仪器,尤其是涉及一种带镜子的音叉。在音叉一股外侧的上部设有一平面镜。实验时用一束激光照射到平面镜,经反射后投射到远处的白墙上,当敲击音叉时,墙上的光点会发生振动,学生就能从墙上光点的振动体会到音叉的振动。所以本实用新型具有结构简单、操作方便、成本低廉等优点。

Description

带镜子的音叉
所属技术领域
本实用新型涉及一种教学仪器,尤其是涉及一种带镜子的音叉。 
背景技术
目前在课堂教学中演示音叉的振动一般是用手触摸的方法,不能让全体学生直接观察得到。 
发明内容
本实用新型的目的是提供一种这样的带镜子的音叉,上课演示时能让学生直接观察到。 
本实用新型解决其技术问题所采用的技术方案是:在音叉一股外侧的上部设有一平面镜。 
本实用新型的有益效果是:由于采用了上述方案,在做实验时,学生能直接观察到音叉的振动,而不要用手去触摸。所以它有结构简单、操作方便、成本低廉等优点。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。 
图中所示的是本实用新型的结构示意图; 
图中1、音叉,2、平面镜。 
具体实施方式
本实用新型可以用胶水在音叉1的其中一股的外侧的上部贴上一平面镜2。实验时用一束激光照射到平面镜,经反射后投射到远处的白墙上,当敲击音叉时,墙上的光点会发生振动,学生就能从墙上光点的振动体会到音叉的振动。所以本实用新型具有结构简单、操作方便、成本低廉等优点。
