Many Electronic circuit projects in simple ways of learning

Free 4 ideas of tone generator circuit using FET, SCR, transistors

If you are looking for a tone generator circuit.  First, you will use IC. Because it is easy and small.  But you can get others ideas of the sound generator.  Sometimes you may like it. Since you may have these components in your store.  I love to look a different circuit. If I have free times. I will build it. Here is 4 circuits ideas list:

Simple Warble tone generator circuit

The Simple Warble tone generator circuit  is see this it , sound generator warbling tone , which hear distinct in swoop down that have a voice disturb , get more than , single tone. By the transistor Tr2-TR3 assemble the circuit tone Generator. Which frequency modulated with output of TR1 which it frequency generator saw tooth sound generator sound signal can fine can decorate with R7 effectively follow want.

Simple Warble tone generator circuit

And still can fine C1 for make which frequency modulated change to with. By a loudspeaker that use to is supposed to impedance 35 ohm railings are if use lower this be supposed to resistors , build serial keep with. For decrease the popularity will down. And may lead output go to feed reach still power amplifier circuit , get change capacitors 4 uF. The detail is other , see in the circuit yes.

Tone Generator Circuit using 2N4891

Tone Generator Circuit using 2N4891

This be Basic Tone Generator by UJT Transistor 2N4891 numbers. By it s can give with small-sized loudspeaker s have a voice electric loud bell moderately. The value of C1 be valuable a little for enhance the speed in the package and disgorge to load. In each round (Cycle) that get be sound frequency at shine depart a loudspeaker. By can fine sound frequency get with R2 – 100K the value Resistance low tall frequency. But if the value is Resistance the tall low voice frequency. This circuit has can to develop next again. Request enjoy something sound electric bell this circuit please sir, be lucky.


Cricket Generator circuit using 2N4891

Cricket  Generator  circuit using 2N4891

This circuit gives sound handful that modifies interestedly, occurrence sound rate cricket Fixed. By R3 should experience change the value C1,R5 and C2 effective that differently. A loudspeaker that use should is model Piezo Tweeter. The Transistor use get many the number. but that use Q1,Q2 be 2N4891 numbers or the number replaces. For power supply source use 9V. Detail other sizes see in the circuit request friends have fun Cricket Generator Circuit.

Electronic bird sound

      Operation of the circuit.When pressed, switch S1. Circuits will work out a sound of birds.The R1, R2, C3 forward control transistor Q1 to work intermittently.

    The capacitor C4 determines the latency time, for each voice singing. In addition, there C2 as the feedback signal.If the C2 is much value,will make the bass sound. However if C2 is less,will make the treble sound. When Q1 bias, will has the current flowing through the primary winding of the transformer T1. Resulting in the induction coil secondary signal to drive speakers.
