ABSTRACT
Audio loudspeaker (output transducer) is on of the most essential and powerful device used in telecommunication system. This is device capable of converting electrical signal into sound and vice versa. It is made up of few time of non-magnetic wire wound on a light cylindrical former that is mounted so that it can move freely insides the magnetic field of a strong permanent magnet. The speaker cone it attached to the voice coil and attached with a flexible mounting to outer ting of the speaker support.
The device was contracted and operated based on the principles of electromagnetic induction which was clearly stated by faradays and langue laws of electromagnetic induction. This speaker has power rating of low watts and 16ohms impedance
The materials used in made up of particle board of ¾ thickness tweeter and cross over network..
This device constructed locally can compete favourably well with the imported one (with international standard) the information in this write up comprises of the construction operation a detailed information of each component parts and various used of output transducer (loudspeaker).
