In summary, an inline microphone is a type of microphone built into a cable for convenient hands-free communication. It has two wires, ground and hot, which carry the audio signal to the device it is connected to. The microphone requires a 1.7V DC voltage to function properly and produces output voltages that may vary. To use an inline microphone, simply plug it into the device and position it close to your mouth for optimal sound quality. Some devices may require adjustments to the microphone settings for best performance.

In a standard set of headphones, the inline microphone only has two leads, ground and hot. I took a multi-meter to the microphone input of one of my devices and there was 1.7V DC waiting.

So I'm wondering how such a microphone operates (just that type of mic in general). I searched online for a diagram, but no success. Does it vary the 1.7V DC that's fed into it?

Also, what output voltage are those inline mics usually at?

Thanks

FAQ: Inline Microphone: Ground & Hot, 1.7V DC & Output Voltages

What is an inline microphone?

An inline microphone is a type of microphone that is built into a cable, allowing for easier and more convenient use. It is commonly used for hands-free communication, such as in headphones or headsets.

What does "ground" and "hot" refer to in an inline microphone?

"Ground" refers to the electrical connection that serves as a reference point for the electrical circuit, while "hot" refers to the part of the circuit that carries the audio signal. In an inline microphone, ground and hot are the two wires that carry the audio signal from the microphone to the device it is connected to.

What is the significance of 1.7V DC in an inline microphone?

1.7V DC refers to the direct current voltage that is required to power the inline microphone. This voltage is necessary for the microphone to function properly and produce an audio signal.

What are output voltages in an inline microphone?

Output voltages refer to the electrical signal that is produced by the microphone and sent to the device it is connected to. This voltage can vary depending on the strength of the audio signal and the sensitivity of the microphone.

How do I use an inline microphone?

To use an inline microphone, simply plug it into the device (such as a smartphone or computer) using the appropriate connector. Make sure the microphone is positioned close to your mouth for optimal sound quality. Some devices may also require you to adjust the microphone settings for better performance.
