Output Voltage Of Computer Audio Jack

What is the typical max voltage out of a PC speaker Jack?

https://electronics.stackexchange.com/questions/37926/what-is-the-typical-max-voltage-out-of-a-pc-speaker-jack

I just measured the voltage from my smartphone headphone jack, which should be similar to what you'd get from a PC headphone jack. I got +/- 1.5v (3.0 volts peak to peak). This was not under controlled conditions with a known audio source. I would guess that the output could peak at higher than +/- 3v (6v peak to peak).

Since I don't want to fry the thing and I'm not really very good with electronics I figured it might be a good idea to ask what the microphone output voltage of, say, an iPhone is? I'm assuming that all I have to do is simply connect N Volts to the 'Mic' part of the 3,5mm jack on the anemometer and connect the 'Ground' section of the 3,5mm jack ...

To develop the same power the voltage needs to be much higher - therefore, they will sound quiet on normal line-out outputs and would require headphone amplifiers designed for this purpose. Source. As a matter of fact OPAMPs ARE used for output stages on computers.

Strangly when i insert an audio to audio cabel into the the smarthphone audio jack the multimeter shows me max. 0.1 V. But if the cabel is just half inserted in the audio jack the multimeter shows me a Voltage of 2.4V

The 3.5 mm headphone jack on the MacBook Pro (14-inch, 2021) or MacBook Pro (16-inch, 2021) features DC load detection and adaptive voltage output. Mac can detect the impedance of the connected device and will adapt its output for low- and high-impedance headphones, as well as for line-level audio devices.

No. Think of it this way: The amplifier that drives the "headphone/line out" jack is an audio amplifier chip. That chip is powered on an internal system voltage, likely on the order of ~6V. This means that the chip can drive the audio output to about 5V peak-to-peak (which is ~1.7V rms) into a high impedance.

“Clipping” occurs if the power is too high; see the last picture with the funky waveforms. If you get an output like this, reduce the power until you have a smoother output. For us, 55% of full volume (680 mV in) from the audio input gave us a clean output of 1.88 V …

Maybe that is what the computer senses to activate the mic input. I recommended adding a 3900 ohms resistor to ground at the mic input to draw 0.4mA DC so the pc senses "a mic". You wrongly show a DC voltage of 1V from your headphones output but it is probably a 1V peak audio signal which is not DC.
