Project Overview

<p> </p><p><strong>BACKGROUND OF THE STUDY</strong></p><p><strong>1.1 &nbsp; &nbsp; INTRODUCTION</strong></p><p>A speaker driver is an individual transducer that converts electrical energy to sound waves, typically as part of a loudspeaker, television, or other electronics device. Sometimes the transducer is itself referred to as a speaker, particularly when a single one is mounted in an enclosure or as surface-mounted device (as in a wall-mounted speaker, car audio speaker, and so on). There are many different types of speaker drivers. The most common ones are the woofer, mid-range and tweeter, as well as subwoofers which are becoming very common.</p><p>Most loudspeakers use multiple drivers and employ crossover networks to route the appropriate frequency ranges to the different drivers. To achieve this passive and inductive elements are used in it desire, they include resistor, capacitor and inductor, operational amplifier etc. In this project, each element will be examined in details and the basic configuration to for a crossover network used today. </p><p><strong>1.2 &nbsp; &nbsp; STATEMENT OF THE PROBLEM</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; With an- ever increasing musical equipments, our listening facilities, too, are becoming more and more demanding. A speaker system with impedance mismatched networks can pass a lot of hearing problems when listening. Music without sharpness or a voice with no depth is quite boring. No one enjoys listening to a speaker system without a precision clarity in it. This issue can be resolved if crossover networks are used to split the audio signal into separate frequency bands that can be separately routed to loudspeakers optimized for those bands. The crossover networks can either be low-pass, high-pass or band-pass. For hi-fidelity output; the combinations is used.</p><p><strong>1.3 &nbsp; &nbsp; SIGNIFICANCE OF THE STUDY</strong></p><p>This project is to design a speaker unit with crossover network using off-the-shelf drivers and an original design for the speaker cabinets. A crossover network would also be implemented to compliment the characteristics of the speakers. The primary reason of the design exercise is for associated learning experience. The quality of the end result is most important factor as this design system will be very useful to the school of engineering during their fasting and prayer meeting, seminar and open occasion. </p> <br><p></p>
