Audio Electronics deals with the circuits that are designed for converting sound/pressure wave signals to electrical signals, or vise versa. These circuits are used to processes and manipulate audio signals to design different types of audio amplifiers, audio mixers, frequency controllers etc..
This section consists of a huge collection of audio circuits with schematics and detailed explanation, to help you build Audio projects and use them for your Audio designs.
We are living in the era of 5G and 5G-enabled devices; however, old technologies like the walkie-talkie system and RF communication system are still paramount in scenarios where a remote, short-distance, cheap, and low-cost communication is required. For example, if you have a building or heavy-weight bearing construction company, then your workers need to communicate with…
Maxim Integrated unveiled the MAX98396 Class D/G speaker amplifier with the industry’s lowest noise and lowest quiescent power consumption, which is nearly five times lower power than similar amplifiers. The 20V digital input audio power amplifier offers 12.7mW of quiescent power to meet and exceed the industry’s power compliance regulations, which support the always-on…
The need for home security alarm systems nowadays is a serious demand. As the number of crimes is increasing every day, there has to be something that will keep us safe. A motion sensor dog barking alarm can be a great choice for that purpose. The sound will alert you when someone approaches the house. They can also deter burglars from deciding to enter a home.

I2S is an Inter-IC Sound protocol that is used mainly to transmit or receive the audio data in a synchronous serial port between two devices. There are many applications where audio communication is required in digital devices such as adding a microphone or adding a speaker output to play some audio.
There are multiple Audio protocols available in…
Analog radios are becoming extinct in this digital world since everything, from movies to songs, is being directly streamed from the Internet today. Let’s see how an Internet radio can be made by leveraging some simple digital electronics, coding, and an active Internet connection. Now, those who are following us regularly might already know that we have built a Raspberry Pi…
VA1200 from Vesper is the piezoelectric MEMS voice accelerometer that enables high-fidelity Voice Pickup (VPU) in earbuds, TWS (True Wireless Stereo), VR (Virtual Reality), AR (Augmented Reality), smart-frames, and smart-glasses. Easily integrated into in-ear hearable products, this disruptive, low-power bone conduction vibration sensor reduces design time and design…
Doorbell is a very common and useful device used in every household. Among electronics students and hobbyists, the doorbell circuit project is quite popular. So, in this tutorial, we are going to build a simple musical doorbell using UM66T melody generator IC. This a very simple and interesting project that requires very few components. The main feature of this doorbell…
On average, 2500 songs are uploaded every hour on Spotify, Apple Music, YouTube, and other streaming platforms which makes 60,000 songs a day and a million music tracks every week. Each day, almost 3-4 hours are spent by average American users listening to their favorite songs. But, have you ever wondered about the technology behind these songs and been amazed by hearing…
