Subbing in a chime for the buzzer
 

I was interested in if it was possible to place a chime from a modern S-Class (circa 2007) into the 300D instead of the buzzer? It would probably take some creative wiring, but I was curious if anyone had ever tried to do it? Or is it too much of a headache to even attempt?

Should be fairly easy actually, the buzzing part of the buzzer unit just gets power to make sound. So you could just remove that part and connect up any other sounding device.

Note that the dinger on a modern merc is not a desecrate unit anymore. Its probably built into the cluster.

At least your car has the nicer sounding buzzer :)

wire it up to a door bell. that'd be interesting for awhile. then annoying.

Or to the dinger from an 80s volvo. They sound like a bell.

if you want to go nuts you can get a Electrobell from a locomotive... make you want to turn the key faster

Get one they use in a Submarine, AHOOOOOGA AHOOOOOGA, Dive Dive.


Charlie :D

It's called a klaxton.

And I actually just had my seat belt buzzer from my '83 240d out and was fixing it. To replace the actual buzzer would mainly depend on the size of what's replacing it. I can pull mine out tomorrow to get actual measurements.

Side note: Is the buzzing noise actually created by arcing electricity for others who actually know more about classic electric circuits?

I know I'd like to know, There;s a couple people around I'd love to swap in a sound chip with a cow mooing. I'd find it amusing

I know I've got one of those fling toys that's a cow that moos... I wonder what the voltage is on it.

The buzzing is created by a buzzer :) Basically a relay connected to itself that cycles rapidly. The sound you hear is the mechanical sound of the relay contact clicking on and off.

The buzzer gets sound from a simple addition of power, A tone generally needs an IC and a speaker. I havent seen one as a stand alone unit, their cost savings is usually realized by adding it to another circuit

Lots of 1980s cars have standalone dinger units. Just like with mercedes the buzzer / dinger was part of the seatbelt reminder and lights on / key in ignition reminder unit. The only problem is lots of those dingers sound... not very good.

I meant stand alone in the sense you could remove it from a donor, attach 2 wires and it would work. In most dingers the actual sound generation will need circuits on the board so you could not just remove it without bringing the whole seatbelt whatever circuit with it. to make it work with 2 wires you would need to understand the donor circuit

Okay. I'm interested in actually making this work. Of course, I'll have to find a modern S-Class in the junkyard somewhere or I'll have to order the chime from MB. That could be a few more pesos than I'd want to spend, however.

I've heard of folks swapping in a GM chime unit for the buzzer on here before but can't find a thread :(. FWIW the buzzer is just a piezo-type element that applies circuit to two disks (one usually copper or steel, the other ceramic) and the resistance causes it to buzz. Used in reverse, the same principle is used by microphones, and I have tons of piezo elements to use as pickups for my electronic drums. Cost: about $0.25 a piece, a buck or two from radioshack with the plastic "buzzer" housing.
