In this modern world of electronics, merging technology and nature gives us a unique project on 'bird sound simulator' circuit design as a simple and useful hobby circuit for electronics enthusiasts. This project emulates the chirping sound of a bird using two transistors used ingeniously as a multivibrator technique. Apart from that the project's power source is very cost effective avoiding bulk power supply transformer in the design. We shall now go deep into the design to learn more and build a useful project.
Know your circuit
A very simple straightforward circuit schematic of this bird sound simulator circuit is given here.
It just uses two transistors and is built around it to produce just like bird chirping sounds you can think of many uses of it to put the circuit in any fascinating project.
Two efficient transistors such as BC148 are employed to work as multivibrator which produces square wave signals which cause the circuit to oscillate and produce sounds like a chirping bird with the combination of resistors and capacitors.
The frequency and duration of the chirps can be finely tuned to closely resemble those of real birds. Study the circuit and how it has been configured and connected to the speaker to produce the sound. A transformerless power supply is used using a resistor diode combination and regulated by a zener diode for stability of the power supply along with a capacitor.
The circuit can be divided into three sections -power supply, multivibrator section and sound output speaker. |

Know your design
The heart of the circuit is designed around the oscillator circuit which produces the chirping bird sound.
The circuit is designed using the two BC148 transistors, the main components for the multivibrator function. It is built in such a way the resistor-capacitor combination makes the circuit oscillate in a multivibrator fashion. The output frequency and duty cycle can be adjusted by the 220K preset. As such the pitch and rhythm of the sound output is achieved to the desired level.
To reduce the space and cost of the project hefty power transformer is avoided in the power supply design. A transformerless power supply is used in this design.
Know your assembling
The circuit can be assembled on any general-purpose Vero board as the design is simple and fewer components are used.
