How a Speaker Is Made

Introduction

Speakers function through basic vibration. Sound travels in the form of waves, and thus your speaker actually creates the sound waves. Your speaker functions at a frequency where it can pump out a lot of sound quickly.

Dynamic Speaker Design

One of the most common types of speakers is the dynamic speaker. The dynamic speaker usually consists of a few different parts. A frame is made out of aluminum, the magnet is made out of ferrite, a type of iron, and the cone is made out of paper, or another easily flexible material. The dynamic speaker sends audio signals through a coil, which is connected to an audio amplifier. Once the sound travels through the audio amplifier, the voice coil travels back and forth, creating even more sound. There are four subsets of dynamic speakers. These subsets are full-range, tweeter, midrange and woofer, with each functioning in a different sound range.

Types of Dynamic Speakers

A full range speaker can produce most sounds in the human hearing range, but not all. Most extreme sounds require another type of speaker. A tweeter speaker is used for high frequency sounds. Tweeter speakers are extremely tiny, and do not use much power when compared to other types of speakers. Midrange speakers go lower on the audio spectrum, while woofers and sub woofers cover the lowest parts of the audio range that humans can hear.

Combination Speakers

While the different types of speakers allow you to hear different sounds, many speakers are being combined in order to allow people to hear the largest sound range with the smallest speaker possible. Currently, this process is allowing for the creation of smaller and smaller radios and other portable electronic devices. Technology is playing a large role in how speakers are produced. Soon, it will no longer be necessary to have a cone in the speaker in order to have it produce vibrations. There are methods being worked on that will allow for the sound to be generated straight to the amplifier.

Conclusion

Large scale manufacturing of speakers has come a long way. Not only has the process been sped up incredibly, but the amount of speakers that can be produced has been increased as well. Technology has helped humans create speakers that can serve multiple roles without having to have multiple speakers installed. Speakers including full-range, tweeter, midrange and woofer, have different ranges of sound that they cover. However, each speaker will help serve the purpose of hearing the entire possible spectrum of human audible sound. Soon, technology will be able to increase the range of sounds that humans can hear. Speakers that consist of a cone, amplifier and voice coil are constantly being replaced with more up to date designs, involving less parts and great audio output.
