Components of loudspeaker : A loudspeaker consists of permanent magnets, basket, voice cails, flexible supension & rigid speaker cone as shown in figure. Loudspeaker principle A light voice coil is mounted so that it can move freely inside the magnetic field of a strong permanent magnet. the paper cone is attached to the voice coil and attached with a flexble mounting to the outer ring of the support .Because there is a definite equilibrium position for the speaker cone and there is elasticity of the mounting structure, there is inevitably a free cone resonant frequency like of a mass on a spring. The frequency can be determined by adjusting the mass and stiffness of the cone and voice coil Working : The ratio drives a rapidly changing current through the coil. The current follows that vibrations of speech and the electromagnetic force follows the current changes, pushing the paper cone. Finally the air in front of the loudspeaker is set into vibration following the cone's motion, and sound waves are transmitted to the listener The principle of loudspeaker is :

A man standing 25 m away from a wall produces a sound and receives the reflected sound. Calculate the time after which he receives the reflected sound if the speed of sound in air is 350 m s^(-1) .
