Who knows how to make a squeaker?

Added 14 comments
I want to make in my Lada to be heard when the turn is on. The turn light is exactly in front of the steering wheel and I don’t see it, I have to bend down specially and see if it blinks there or not. And during the day it’s generally not visible nichrome.

I just thought to connect a speaker to the relay, but it will just click. Not interesting, I wanted a tone. What can be connected to the speaker so that a tone appears?

The relay is ordinary, thermal, mechanical.

Of course, the order of the contacts on the circuit of the relay may be wrong, I don’t remember how it is

And the capacitor must be with an operating voltage of> 12V. Forgot to write. You can ceramic, you can electrolyte.

that long song. I connected the relay through the diode to the tape recorder's column: wink: At first, the sound was certainly too powerful, I put the capacitor in series, and a pretty nice and quiet click came out. The smaller the capacity, the quieter the clicks.

Now there will be much less nerves on the road. Turned on and immediately everything is clear.

I wrote - to solder the simplest multivibrator .. Schemes, I think, the sea on the Internet.

Well, damn it, when you apply voltage to the speaker, I want it to buzz or squeak.

Well Classic, from a penny to six :)

Yes, there is a separate output specifically for the panel, you can connect it to it. The problem is in tone. Well, all right, I’ll just connect the speaker to the edge. I thought maybe someone knows how to simply change the tone.

In general .... you can power the relay ... another relay, and from it - an audible signal. )))))))). And fasten it to the rack, directing it to the left ear)))))

In my youth, I assembled a simple multivibrator on two transistors MP38 and MP42 (direct and reverse). He put on a motorcycle. Now I do not understand why))))
And in the car, it is not at all necessary ... It will get out, as they correctly noted. Especially when you have to stand on the emergency gang. But what, is it not heard clicks relyushki? Well they are a specialist in all cars with this purpose in the cabin. Normally they are usually heard ...

they say that the capacitor can be put in series with the speaker, the tone will change, I'll try tomorrow

Better let it snap than squeak. I’ll get tired immediately. Put an additional parallel to the control light, another in a conspicuous place.
