Electronic Design: Wind Sound Generator Circuit using Transistor

Generator Circuit. - This is the other electronic design circuit for implementating of transistors and transformer in this time for you. This electronic design circuit mentioned with wind sound generator using transistors as the major component used.

The electronic design circuit of wind sound generator circuit look like shown in Figure 1 below. From the circuit shown, that there many other major component used like resistor, capacitor, speaker, and transformer.

Beside we will show you electronic design circuit and component parts need, we also will give you global description about this circuit. So, please enjoy to continue reading this article until finish and get more useful.

Description

The electronic circuit design like in Figure 1 above show you wind sound generator circuit using transistors. Other component need also that can supply with low voltage DC 9V source to charge this transistor and all system component. With this electronic design circuit you can produce wind sound generator that useful now.

According ElectronicProjects blog mentioned that using this simple circuit, one can generate the sound of wind. The circuit is basically an astable multivibrator build around two NPN transistors.
By adjusting the 1M potentiometer (VR1), the sound can be changed from that of wind to storm, sound of sea, hiss of escaping gas from a container through a small hole etc. A 9-Volt or 6-volt unregulated power supply is enough. How-ever, a battery may be used instead. The output sound will be slightly changed. The prototype has been successful tested with the given power supply. Also and 8-ohm, 5cm, low wattage speaker is recommended.
