High Frequency Sound Generator Circuit
This tone generator circuit is suitable for indicators emergency alarms etc.
High frequency sound generator circuit. This will increase decrease the frequency by 1hz at a time. High frequency waveform generator is very useful in electronic experiment and design. Copy the circuit drawing above and you can have both. The circuit can also easily allow for amplitude adjustment.
The circuit can be mounted in a plastic box like i have done. This is a simple high pitch noise generator circuit. Radioshack sells a digital voltage meter which has a setting for frequencies. To adjust it by 0 001 hz press ctrl shift and ctrl shift to halve double the frequency go down up one octave click and 2.
This circuit generate sine wave oscillation but actually we can modify the circuit to generate triangle or square wave function. The circuit consists of two astable multivibrator circuits one with a very low oscillation frequency and the other with a high frequency tone. The core of this waveform generator is max038. In the given circuit the multivibrator section ic1 and ic2 has an oscillation frequency about 1hz and 700hz respectively.
To adjust the frequency by 0 01 hz press ctrl and ctrl. If you hold the shift key at the same time the frequency will change by plus or minus 10hz at a time instead. Instantly it says the exact frequency the dial is tuned too. A function generator is a electronic device that can produce a variety of different waveforms.
You can smoothly increment the frequency by clicking in the generator s input box and pressing and holding the up or down arrow on your keyboard. The good thing about high frequency sounds is that it is very hard to find where they are coming from. This circuit generate sine wave oscillation. All i do is connect the output from the generator to the meter s input wires.
We get ours through a potentiometer. It has a timer oscillator with a frequency variable from 15khz 30khz. Like standard function generators the circuit allows for frequency adjustment.
