How to Make Ultrasonic Directive Speaker Circuit
In this post I have explained the construction of a ultrasonic directive speaker system also called parametric speaker which may be used to transmit an audio frequency over a targeted spot or zone such that the person situated exactly at that spot is able to hear the sound while the person next to him or […]
Modify Human Speech with this Digital Voice Changer Circuit
In this post I have explained a voice modulator circuit which will change or transform an individuals unique voice into a completely new form. The new voice will be different to the original voice tone and unrecognizable. The Circuit Concept The characteristic tone of every individuals voice is specifically unique in all circumstances. How often […]
Music Triggered Amplifier Speaker Circuit
The circuit idea I have explained below enables a power amplifier loudspeakers to switch ON only when there’s an input music available, otherwise it makes sure that the loudspeakers remain shut off. The idea ws requested by Mr. David Alda. Technical Specifications Your site is just awesome. I’m hoping you can post a tweak to […]
