While using amplifiers, we sometimes experience this very annoying thump sound, popping up in loudspeakers whenever the amplifier is switched ON or OFF. This normally happens with amplifiers that are of low quality or lack the feature of a thump eliminator circuit built-in in the amplifier. The thump sound in loudspeakers can be not only […]

Electronic Drum Sound Simulator Circuits
In this post we talk about a couple electronic drum sound simulator circuits which can be used for replicating actual drum beat sound electronically, using a few op amps and few other passive electronic components. Using Capacitor as the Sensor Instead of Piezo Conventional electronic drum kits incorporate the use of piezo disc affixed to […]
Making a Center Speaker Box C80 for Surround Sound Systems
A Hi-Fi surround sound system (5.1) typically consists of 4 speakers at the corners of the room, and a center speaker just below or above the TV or the video system. This center speaker becomes the main speaker box of the surround sound since it is responsible for delivering the high quality voice output from […]
Sound Triggered Halloween Eyes Project – “Don’t Wake the Devil”
This can be a perfect circuit project for Halloween, although sound activated gadgets likewise may have plenty of other applications. When somebody enters the Halloween house, a sensitive MIC detects the sound vibrations and spins the eye balls of the scary looking beard man, as if it was waken up by the sound, and is […]
Laughter Sound Simulator Circuit
As the name suggests, this device generates electronic sound, resembling human laughter. BASIC DESIGN To enable the circuit start the proposed operations, it must have a fundamental sound input or frequency for processing. This basic frequency is established through a simple oscillator operating at 1 kHz frequency. The next, requirement would be to process this […]
Loud Pistol Sound Simulator Circuit
The proposed circuit is an oscillator circuit designed to generate a loud pistol like sound over a loudspeaker. A pistol sound generator circuit presented here can be used as button operated starting sound during racing events or marathons, or simply to deter wild animals and thieves in remote areas. The concept could be also effectively […]
