        揚聲器又稱喇叭是一種十分常用的電聲>換能器件,在發聲的電子電氣設備中都能見到它。

        揚聲器在音響設備中是一個最薄弱的器件,而對于音響效果而言,它又是一個最重要的部件。揚聲器的種類繁多,而且價格相差很大。音頻電能通過電磁,壓電或靜電效應,使其紙盆或膜片振動并與周圍的空氣產生共振(共鳴)而發出聲音。按換能機理和結構分動圈式(電動式)、電容式(靜電式)、壓電式(晶體或陶瓷)、電磁式(壓簧式)、電離子式和氣動式揚聲器等,電動式揚聲器按紙盆形狀分圓形、橢圓形、雙紙盆和橡皮折環;按工作頻率分低音、中音、高音,有的還分成錄音機專用、電視機專用、普通和高保真揚聲器等;按音圈阻抗分低阻抗和高阻抗;按效果分直輻和環境聲等。
