The history of audio systems can be traced back to the early days of recorded sound when the first phonograph was invented in 1877. The phonograph, which used a cylinder to record and play back sound, soon gained popularity as a way to listen to recorded music and other media.

The invention of the radio in the 1920s marked the next significant advancement in audio technology. The radio quickly gained popularity as a popular means of staying informed and amused since it allowed people to listen to live music and news broadcasts.

Over the years, audio technology has undergone an interesting evolution. The invention of digital audio players like the iPod in 2001 and streaming services like Spotify and Apple Music have made it simpler than ever to access and enjoy music.

Today, a wide range of gadgets, including smartphones, tablets, and smart speakers, allows consumers to listen to music.

With the introduction of virtual reality and artificial intelligence technology, audio systems are predicted to become even more powerful and immersive in the future.

Todun is a manufacturer of audio and video conference system equipment. We produce high-quality audio-listening products.

What is the audio system?

An audio system is a group of devices that are used to playback, amplify or record sound. It can consist of equipment like speakers, amplifiers, and microphones as well as audio equipment like CDs, records, or streaming services.

An audio system’s fundamental parts are a sound source, an amplifier, and speakers.

Sound source

Several devices, such as CD players, turntables, digital audio players, or computers, can be used as sound sources.


The device that amplifies the original sound from the source and transfers it to the speakers is described as an amplifier.


The speakers are the components that transform the amplified sound into audible sound waves that we can hear.

They are available in a variety of styles, including bookshelf speakers, floor models, in-wall models, and in-ceiling models. They are either wireless or wired.

Other components that can be included in an audio system are equalizers, crossovers, and subwoofers.

  • An equalizer enables you to alter the sound’s frequency balance
  • A crossover separates the various frequencies and sends them to the proper speakers
  • A subwoofer is a specialist speaker made to create low frequencies.
