The following article presents a simple sound operated/activated amplifier muting circuit which enables the amplifier to silence itself as soon a voice or an external sound occurs across the detector MIC. The circuit was requested by Mr. Seok Sothea. Technical Specifications I want to make a circuit about voice interrupt music..this circuit consists of two input, audio […]

Simple Surround Sound Decoder Circuit
This article is written with an intent to explain in detail behind the making of a simple surround-sound decoder circuit. By: Dhrubajyoti Biswas Overview The concept of the decoder was first introduced by David Hafler in the 70s. His research illustrates the way to use two speakers as rear speakers on a surround system. The […]
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 […]
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 […]
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 […]
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 […]
