Simulating a sound.

[Rumieus]

Im currently trying to simulate a siren circuit using multisim but no luck.
How do you simulate a sound using multisim? or is there any other software that can simulate a sound from a circuit?
Tq.

Please post the circuit.

LTspice has the ability to create WAV files from simulation circuit nodes.

I've used MultiSim in the past, but don't remember having the ability to simulate a speaker or buzzer. But that doesn't mean it doesn't. I've just never used it.

 

[Rumieus]

This is the circuit I try to simulate.
Can anyone try it and see if you guys can make it works.

 

[Hero999]

There shouldn't be any need to simulate such a simple circuit, it will work providing you assemble it correctly and all the components work.

I just want to simulate it and play around with it..
Learning electronics..
Of course this circuit would work..
If I just buy the part and assemble it, I wouldn't need a simulator..
I already done that in my final project and gain nothing.. just a high marks..
Hehe

I don't think you'll learn much by having one of us run the simulation. Try to simulate it in LTspice. LTspice has a good help file.
If you get stuck, post what you have done (you can attach .asc files here, which are the LTspice schematic files). We'll try to help.

Someone ask me to post the circuit, so I did.
Maybe there is no software that can simulate a sound?

 

[Hero999]

LTSpice can - he's already told you that.

The circuit is silly for using two 555s instead of the dual 556.

 

[Roff]

Maybe he doesn't know what a WAV file is.

i know what a wav file..
just downloaded ltspice/swcad iii..
anything i will ask you guys..
tq very much..

What is you motivation for wanting to simulate a siren?

Do you have any parts to work with? Simulators are OK, but you'll probably learn more by actually putting circuits together. You can use buzzers to simulate sirens if that's what you're after.

 

[Rumieus]

Em money is a problem..
I don't have much to spend on component and electronic tools..
I put the buzzer and still no sound..

Maybe I wrongly connect the circuit in multisim?
I'm totally a noob..

TQ for your time and help.

You would learn a lot about the siren circuit by connecting an oscilloscope and seeing the waveforms, instead of simulating them.

 

[audioguru]

Your new circuit is supposed to sweep the audio frequency up and down. The "buzzer" is supposed to be a speaker. It won't work with a buzzer.

 

[Rumieus]

What is to see in oscilloscope?
How to know what sound it makes? By watching waveform?
I remember back when i was studying electronics, all I do is measuring peak to peak, watching the waveform changes by changing the time/div volt/div..

 

[audioguru]

An oscilloscope will show if the frequency jumps from one frequency to the second frequency like sirens in Europe, or if it smoothly sweeps the frequency like sirens in North America. It shows if the wavform is a square-wave which makes a buzzing sound or if it is a sine-wave which makes a smooth sound.

If you want a sine-wave smooth sound then an oscilloscope will show if the circuit is clipping the top, the bottom or both which will make it buzz.
