Ohhhh, I see. I guess you would just desolder the buzzer two pins and solder in two wires connected to a cable with a 3.5mm audio jack. Might need to stick an attenuator if it's too loud or an amplifier if it's too quiet, but it's simple enough to just do this first and check. Don't be wearing your headphones when you first test it.I think he wants to hear the buzzer buzz in his headset, not to hear speech or music.
Then whatever activates the buzzer with 5V can power an oscillating opamp or something that can drive the headset.
Suitability of the backup buzzer for airplane ground warning aside...My situation..
I have a "backup beeper" that increases the sound interval frequency the closer the sensor gets to something.
I want to use this in my airplane, 'on landing' the closer I get to the ground the faster the beeps. It's very noisy without headsets, and wouldn't be able to hear the current buzzer.
As far as what type of sound chip, a beep or buzz. I just cannot seem to find anything close searching "Sound output chip" among other things. What I do find are small boards with buzzer like mine soldered to them.
So what I need is something that creates a digital sound I can send to my intercom.
That is exactly what the b1tch-in-the-box tells me every time I purposely fly too close to a mountain top. She gets downright insistent on the second and third warning... She says "obstacle ahead" if I fly too close to a radio tower...The beeper is supposed to say, "Pull Up Terrain, Pull Up Terrain" like they do on the TV show Mayday.
