This final paper starts with the definition and characteristics of sound. Before we go back in time to see the first speakers and how they developed, we will briefly describe the speakers. After the introductory part and introduction to speakers, we will learn that speakers can be divided into several types and by different categories. The most used type are dynamic speakers, and the focus of this paper will be exactly on them. There are several types of dynamic speakers that can be divided according to the frequency band. We will see that the speakers are stored in speaker enclosures, which are important for their acoustic characteristics, but also for their aesthetics. Several speakers can be combined in enclosures, which gives us a speaker system that can cover a certain range or the entire band of frequencies that the human ear can recognize. High quality speaker systems usually have several speaker enclosures and every enclosure is responsible for different frequency band. In the practical part, we will see how a simple version of the dynamic speaker looks like. We will need a list of the components that will be used, design process will be described, and at the end the speaker will be analyzed.
