WHELEN于1952年發(fā)明了  個旋轉航空燈塔，由此創(chuàng)立了WHELEN公司。WHELEN  航空燈的發(fā)展幫助惠倫進入汽車安全照明行業(yè)。  防，EMS和DOT專業(yè)人員以及許多其他行業(yè)提供安全照明。汽車領域的產(chǎn)量使惠倫能夠投  自動化裝配設備，以便在  圍內展開競爭。在二十世紀七十年代，惠倫推出了室外警報警號 - *電子化，不僅能夠警告音，還能夠發(fā)出高功率的語音信息。WHELEN的目標是將創(chuàng)新的救生產(chǎn)品更快地推向市場，同時在整個過程中保持嚴格的質量控制。

　運算放大器具有雙電源和單電源兩種供電方式，對于采用雙電源供電的運放而言，其輸出值允許在零電壓上下變化，差動輸入電壓為零時也可將輸出置零;而對于采用單電源供電的運放而言，其輸出值僅允許在電源與地之間的某范圍內進行變化。

　　對于一般運算放大器而言，其輸入電位要求在負電源上面某數(shù)值到正電源下面某數(shù)值范圍內，但經(jīng)特殊設計后也可以使其在負電源至正電源整個范圍內變化，甚至稍高于正電源或稍低于負電源，這種運放被稱為軌到軌輸入運算放大器。

１、揚聲器的結構

揚聲器有許多種類，但其基本的工作原理是相似的，均是一種將電信號轉換為聲音信號進行重放的元件。目前使用最為廣泛的是電動式揚聲器，它由振動膜、音圈、磁鐵、支架等組成。

２、揚聲器的工作原理

當揚聲器的音圈通入音頻電流后音圈在電流的作用下便產(chǎn)生交變的磁場，磁鐵同時也產(chǎn)生一個大小和方向不變的恒定的磁場。由于音圈所產(chǎn)生磁場的大小和方向隨音頻電流的變化不斷地在改變，這樣兩個磁場的相互作用使音圈作垂直于音圈中電流方向的運動，由于音圈和振動膜相連，從而帶動振動膜產(chǎn)生振動，由振動膜振動引起空氣的振動而發(fā)出聲音。當輸入音圈的電流越大，其磁場的作用力就越大，振動膜振動的幅度也就越大，聲音則越響。揚聲器發(fā)出高音的部分主要在振動膜的中央，當揚聲器振動膜的中央材質越硬，則其重放的聲音效果越好。揚聲器發(fā)出低音的部分主要在振動膜的邊緣，如果揚聲器的振動膜邊緣較為柔軟且紙盆口徑較大，則揚聲器發(fā)出的低音效果越好。另外，球頂揚聲器在日前市場中的音箱中使用很多。大家知道，高音揚聲器由于其工作頻率很高，在重放高音時其振膜會在磁鐵的的磁路氣隙中作高速運動，因此要求高音揚聲器的振膜能夠對瞬變的高頻信號作出迅速的反應．并且能夠承受高速運動而產(chǎn)生的空氣壓力，因此對于振膜的制作材料要求質量要輕，并要有足夠的強度。
