The physical size and power handling of the speaker, combined with the volume set by the output, can push this number up to 100V or more. Big speakers have large, stiff components that need a lot of juice to move. Because of the higher voltage and wattage used by speakers, we connect them up using heavy-gauge, bare-wire speaker cable.
headphones - Understanding voltage levels on 3.5 mm audio ...
https://electronics.stackexchange.com/questions/298573/understanding-voltage-levels-on-3-5-mm-audio-output
When no audio is playing, there's a voltage of about 2 mV. When I output a constant audio signal, the voltage rises initially to 0.5 V, but drops back to 2 mV after 2-3 seconds. What purpose does this 2 mV bias voltage serve? Does audio output circuitry usually contain DC blocking capacitors, or is DC blocked via some other means? audio headphones

While "line level" audio is typically 1 mW into 600 Ω, and this comes out to 1.1 V p for a sine, audio is far from a sine. Even if the spec is adhered to and you only get 775 mV RMS on average, the peaks can be considerably higher than 1.1 V. It is generally good to accept and handle without distortion peaks up to ± 5 V at least. Share
Computer Audio Amplifier Circuit with Preamplification
https://circuits-diy.com/computer-audio-amplifier-circuit-with-preamplification/
The IC TDA7056 is a 3 Watt audio amp IC. Moreover, the total quiescent current of the IC is as low as 5mA to 7mA. But here the audio amplifier has a preamplifier. Preamplification is carried out by the transistor 2N4401. The weak audio signal from the computer goes from a stereo plug into the amplifier circuit.
How to connect your computer audio output to your …
https://www.ramelectronics.net/howto-pc-audio.aspx
The easiest way to connect the audio output of your computer is to use the "line" output of your sound card. We recommend a stereo 3.5mm mini phone plug to dual RCA cable or mini plug to dual RCA jack adapter with a RCA jack stereo cable to go to the audio input of your sound system, such as the "aux" input. The longer the length of the cable ...
