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.
You must have seen someone speaking on the MIC and the amplified voice coming from the speaker, how this is possible? Is there any circuitry between MIC and speaker of we can directly connect Microphone with speaker to get it working? In this circuit, we learn to build a simple Microphone to Speaker system, in which input sound is given to the MIC and we hear the amplified…
At many places, like public speeches or some musical program, where loudspeaker is used, we hear music and voice from the same speaker. You might have noticed that as soon as someone starts speaking into the microphone, the music from the loudspeaker stops and we start to listen the voice of the speaker. And vice versa when person stops speaking, the music starts again. In…
Power amplifier is the part of audio electronics. It is designed to maximize the magnitude of the power f given input signal. In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load. In this tutorial, we will build a 100W RMS output power amplifier circuit using …
ROHM has launched a new branding “MUS-IC” for its solutions for high-fidelity audio products, which includes a range of D/A converter ICs (DAC ICs), optimized for high-fidelity reproduction, and power supply products.
The increasing adoption of high-resolution audio sources has strengthened the demand for audio…

Infrared is the most commonly used wireless data transfer medium for limited range, and we already covered about simple IR Transmitter and Receiver circuit. Today in this Article, we will learn how to build a Crude Wireless Audio Transfer Circuit Using IR LEDs. Using this circuit you should be able to play songs from your IPod, mobile or computer to an external speaker…

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words…
One of the cool projects I always wanted to build is an FM transmitter with a good range. I have always been fascinated by some of the applications of the transmitter, especially when I was younger and, like everyone else, spent most of my time imagining how cool it would be to have some of the equipment and devices used in spy movies. So recently, while going over one of my…
A transformer is a static electrical device that transfers energy between two or more circuits through electromagnetic induction. The transformer can Step up or Step down signal voltage. The transformer has no direct connection between the primary and secondary windings, the electrical energy transferred using electromagnetic induction. Due to this…
