Electronic bird sounds

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.
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.

Create natural sound using ic MM5837

Normal voice we hear is from frequencies that are a combination of both high frequency and low frequency. Signal strength is not equal, will result in a different voice.

Operation of the circuit. When the power supply to IC1 by IC1 will work out the frequency produced by the pin 13 pin 3 is press the switch on left off. C to a value that will be connected to each circuit by the C makes the sound different.

Of the signal from pin 3 of IC1 is through R1 and VR1 is responsible for adjusting the strength of the signal will be expanded to IC2, which IC2 is IC amplifier with growing 1W signal that originates in the leg 5. The high frequency. And noise will be R3, C8 filter to ground the remaining signal is Retail Oil Link to C9 on the speakers.

Mini Trombone Sound generator by LM3909

This be Mini Trombone Sound generator circuit. By using integrated circuit the number LM3909 of NS. In using loudspeaker 25 Ohm sizes work by use voltage from AA 1.5V battery. In sound occurrence that resemble with trombone.
It have the work depends on the principle uses voltage, which the generator by the occurrence Resonance of sound coil of a loudspeaker is feeding gets back to the way adds to give with integrated that circuit was set up in large-sized box,which there is the capacity about 64 inch cubic which one side of a box has can to move in and out resemble a cylinder a position of a piston.
The work of switch press will cause the tone of voice that resemble very integrated loudspeaker circuit and battery touch set up on a piston , which there are 5 size inch pipes. For be born air push reaches and go out while a piston moves by don’t affect to build the frequency Resonance. The frequency of origin frequency circuit will begin to equal to the frequency Resonance of a box.
