 A LOUDSPEAKER IS AN ELECTROACOUSTIC TRANSDUCER, A DEVICE WHICH CONVERTS AN ELECTRICAL AUDIO SIGNAL INTO A CORRESPONDING  SOUND. THE MOST WIDELY USED TYPE OF SPEAKER IS THE DYNAMIC SPEAKER. THE SOUND SOURCE AMPLIFIER BEFORE THE SIGNAL IS SENT TO THE SPEAKER .

THE DYNAMIC SPEAKER WAS INVERTED IN 1924 BY EDWARD W.KELLOGG AND CHESTER W . RICE. THE DYNAMIC SPEAKER OPERATES ON THE SAME BASIC PRINCIPLE AS A DYNAMIC MICROPHONE, BUT IN REVERSE, TO PRODUCE SOUND FROM AN ELECTRICAL SIGNALS. WHEN AN ALTERNATING CURRENT ELECTRICAL AUDIO SIGNAL IS APPLIED TO ITS VOICE COIL OF WIRE SUSPENDED IN A CIRCULAR GAP BETWEEN THE POLES OF A PERMANENT MAGNET, THE COIL IS FORCED TO MOVE RAPIDLY BACK AND FORTH DUE TO FARADAY'S LAW OF INDUCTION, WHICH CAUSES A DIAPHRAGM ATTACHED TO THE COIL TO MOVE BACK AND FORTH  , PUSHING ON THE AIR TO CREATE SOUND WAVES . BESIDES THIS MOST COMMON METHOD, THERE  ARE SEVERAL ALTERNATIVE TECHNOLOGIES THAT CAN BE USED TO CONVERT AN ELECTRICAL SIGNAL INTO SOUND.

SPEAKER ARE TYPICALLY HOUSED IN A SPEAKER ENCLOSURE CABINET WHICH IS OFTEN A RECTANGLE SQUARE BOX MADE OF SEVERAL FORMS OF WOODS OF WOOD, OR SOMETIMES PLASTIC.THE ENCLOSURE'S MATERIAL AND DESIGN PLAY AN IMPORTANT  ROLE IN THE QUALITY OF THE SOUND.THE ENCLOSURE 'S  MATERIALS AND DESIGN PLAY AN IMPORTANT ROLE IN THE QUALITY OF THE SOUND. THE ENCLOSURE GENIALLY MUST BE AS STIFF AND NON-RESONANT AS PRACTICALLY POSSIBLE. WHERE HIGH FIDELITY. REPRODUCTION OF SOUND IS REQUIRED, MULTIPLE LOUDSPEAKER TRANSDUCERS ARE OFTEN MOUNTED IN THE SAME ENCLOSURE, EACH REPRODUCING A PART OF THE AUDIBLE FREQUENCY RANGE. IN THIS CASE, THE INDIVIDUAL SPEAKER ARE REFERRED TO AS DRIVERS AND THE ENIRE UNIT IS CALLED A LOUDSPEAKER.

                           DIVERS MADE FOR REPRODUCING HIGH AUDIO FREQUENCIES ARE CALLED TWEETERS, THOSE FOR MIDDLE FREQUENCIES ARE CALLED MID RANGE DRIVERS AND THOSE FOR LOW FREQUENCIES ARE CALLED WOOFERS. EXTREMELY LOW FREQUENCIES [16Hz-100Hz] MAY BE REPRODUCED BY SEPARATE SUB WOOFERS.
