convert an electrical signal from a radio‚ television set or electric musical instrument into sound. For a loudspeaker to produce sound‚ the signal from the radio‚ television set‚ or electric musical instrument needs to be connected to an electronic amplifier. Loudspeakers are usually built by using stiff paper cone‚ a coil of thin copper wire‚ and a circular magnet. The cone‚ copper wire‚ and magnet are usually mounted in a rectangle-shaped wood cabinet. The coil of copper wire moves back and forth

Limitation of hearing can be overcome by using appropriate hearing aids such as microphone‚ stethoscope‚ amplifier and others. Function: A microscope is an instrument used to see objects that are too small for the naked eye. Telescope Function: A telescope is used for viewing distant objects like stars‚ planets‚ the moon and others. Periscope Function: A periscope

final design and its parameters may differ with some little modification according to the market availability of components and instruments to be used. Transistor Circuit Design: This two transistor simple FM transmitter is built around two amplifiers‚ Q1 is a common emitter with a dc gain of 1 and Ac gain that can be set by potentiometer R4 and this will amplify the signal from the electret and pass it to the next stage by coupling capacitor C3.
