What Are Audio Amplifiers? How Do They Work?

By on March 9, 2022

Did you know that in 2020, 15 million new people bought streaming music subscriptions? Spotify has the most subscriptions with 31 percent of the market.

This music streaming service has many songs available for its subscribers. Some enjoy direct streaming alone, while some share this music with friends.

If you intend to share music with the public, a single phone speaker is not enough. You’ll need audio amplifiers to intensify the volume and have an excellent time.

Do you want to know about these music enhancers? Read more and learn the different mediums for great moments.

What Are Audio Amplifiers?

Amplifiers are audio enhancers that amplify small electrical signals. It receives a signal from mobile devices, cd/media players, and others.

The amplifier enlarges that original small signal to be louder. Even though amplifiers are mysterious black boxes, this tool is simple to understand.

An AudioControl can be distinct in various ways. It can be by voltage, frequency, power, and construction. It has three subgroups to amplify audio frequency which are:

  • Preamplifiers
  • Power Amplifiers
  • Stereo Amplifiers

Preamplifiers receive weak signals like mic-level signals, making them higher-level. Power amplifiers make the signal louder enough to amplify it for loudspeakers.

Stereo Amplifiers have various output receivers from devices. These amplifiers have connections to speakers, producing the sound for a bigger audience.

Choosing an audio amplifier is not complicated because stereo amplifiers are the best today. They improve the quality of the sound by using a system of speakers. That said, you’ll have the best time with friends in the company of quality music.

How Do They Work

To understand these amplifiers more, let’s see how it operates. The best audio amplifiers work through a power supply. The amplifier section receives 110-volts power, and this electrical current converts.

This current is direct and is present in batteries or power supplies. The electric current flows in a transistor from the power supply. That part of the amplifier segregates the current volume.

The input source then sends a signal. It reduces the transistor resistance to allow current flow. But there’s a catch to this: the current flowing has a basis on the source’s signal size.

The bigger the signal, the more flow allows a better amplification of the original signal. Moreover, the frequency sets the transistor’s speed operation system. If the tone sets to 100 Hz, the transistor will close and open 100 times per second.

The transistor is the valve that controls the level and frequency of the flowing current. It’s how amplifiers work, so now you can get an amplifier for yourself. Read some audio amplifier buying guide to go with you.
