WHELEN于1952年发明了  个旋转航空灯塔,由此创立了WHELEN公司。WHELEN  航空灯的发展帮助惠伦进入汽车安全照明行业。  防,EMS和DOT专业人员以及许多其他行业提供安全照明。汽车领域的产量使惠伦能够投  自动化装配设备,以便在  围内展开竞争。在二十世纪七十年代,惠伦推出了室外警报警号 - 完全电子化,不仅能够警告音,还能够发出高功率的语音信息。WHELEN的目标是将创新的救生产品更快地推向市场,同时在整个过程中保持严格的质量控制。

 运算放大器具有双电源和单电源两种供电方式,对于采用双电源供电的运放而言,其输出值允许在零电压上下变化,差动输入电压为零时也可将输出置零;而对于采用单电源供电的运放而言,其输出值仅允许在电源与地之间的某范围内进行变化。

  对于一般运算放大器而言,其输入电位要求在负电源上面某数值到正电源下面某数值范围内,但经特殊设计后也可以使其在负电源至正电源整个范围内变化,甚至稍高于正电源或稍低于负电源,这种运放被称为轨到轨输入运算放大器。

1、扬声器的结构

扬声器有许多种类,但其基本的工作原理是相似的,均是一种将电信号转换为声音信号进行重放的元件。目前使用最为广泛的是电动式扬声器,它由振动膜、音圈、磁铁、支架等组成。

2、扬声器的工作原理

当扬声器的音圈通入音频电流后音圈在电流的作用下便产生交变的磁场,磁铁同时也产生一个大小和方向不变的恒定的磁场。由于音圈所产生磁场的大小和方向随音频电流的变化不断地在改变,这样两个磁场的相互作用使音圈作垂直于音圈中电流方向的运动,由于音圈和振动膜相连,从而带动振动膜产生振动,由振动膜振动引起空气的振动而发出声音。当输入音圈的电流越大,其磁场的作用力就越大,振动膜振动的幅度也就越大,声音则越响。扬声器发出高音的部分主要在振动膜的中央,当扬声器振动膜的中央材质越硬,则其重放的声音效果越好。扬声器发出低音的部分主要在振动膜的边缘,如果扬声器的振动膜边缘较为柔软且纸盆口径较大,则扬声器发出的低音效果越好。另外,球顶扬声器在日前市场中的音箱中使用很多。大家知道,高音扬声器由于其工作频率很高,在重放高音时其振膜会在磁铁的的磁路气隙中作高速运动,因此要求高音扬声器的振膜能够对瞬变的高频信号作出迅速的反应.并且能够承受高速运动而产生的空气压力,因此对于振膜的制作材料要求质量要轻,并要有足够的强度。
