Find below is the list of audio amplifier circuits.
In this project, we are going to make a Headphone/Audio Amplifier by using self-designed PCB. This project is mainly designed for amplifying the audio signal from the headphones but we can also use it for amplifying the subwoofer or speaker output, just by switching few jumpers.
When we use headphones with our audio device like mobile, laptop, FM…
If Subwoofer in your music system is not producing enough bass then you can use this simple DIY circuit to enhance the Bass. In this project we are going to design a Subwoofer Amplifier Circuit Using IC TDA2030 with few cheap components. This TDA2030 Amplifier can produce 14watt output and this can be increased upto 30watt by using another TDA2030. Also check our previous…
It is always interesting to build things that could be used in our day to day life and it gets more interesting when the same can be built easily at a very low cost. In this tutorial we will learn how to build a simple yet powerful MP3 player that could play any MP3 song, the volume and track can also be adjusted with the help of push buttons. With some extra effort you can…
Amplifier is an electronic circuit or device which is used for amplification purpose and used mainly in sound reproduction as well in our electronic industry widely. There are many types of amplifier available by using different components like transistor based amplifier, op-amp based amplifier, transformer based amplifier. Sometimes we use a Preamp Circuit in circuits…
555 time IC is very powerful and versatile IC, it can be used in many forms. In this tutorial we are going to see how a 555 IC can be used as Audio Amplifier. A low power audio signal can be amplified using 555 Timer IC.
This circuit is divided into two parts: part one is Preamplifier circuit, which consist a BC547…
Simple Mic audio amplifier can amplify sound that is given from Microphone. This circuit can be used as “Small mic and loudspeaker system” for a small space like a room. This circuit can also be used in many applications like portable music players, intercoms, radio amplifiers, TV sound systems, Ultrasonic drivers etc. It can also be used as sound sensor for…
