DIY Guide: Create a 3.5mm Jack to USB Microphone Adapter for Laptop Using 2 Parts

Best answers LABEL_AI_GENERATED

Can I make a passive adapter that connects a 3.5 mm microphone or headset jack to a laptop’s USB port by wiring two parts together?

No, you cannot connect an analog 3.5 mm microphone signal directly to USB with a simple wire adapter; the USB side needs conversion electronics, so “adapters” are really USB sound cards [#16382461][#16382886][#16382892] A 1:1 pin connection is not possible here because USB and analog audio use different signals and contacts [#16382461][#16382892] If you want to use your headset/mic with the laptop, you need a USB audio adapter/interface that contains the necessary electronic circuitry, not just a passive connector [#16382892]

    As the topic. I have 2 parts to do this item. My point is for someone to prompt or draw which pin to which should be connected to make everything work. I will connect a microphone to this, because I have a 2x 3.5 jack headset and I only have 1 input in the laptop: / I would like to do this adapter without any loss of money.

    Even if you try, it will look bad. And I'm not saying you don't have the ability or you can't. There are adapters literally for ~ 12 zlotys to buy, but they can hide some additional electronic elements under the housing. And here the trouble can arise. So I don't know if a 1: 1 connection is possible.

    And now my question is. I can see, the item on the left is a female jack?

    @Sinister Do you know what you are writing about? Do you want to connect the analog audio signal to USB ???

    You can see this is a tired female jack. Ie the predecessor wrote that there is NO direct connection possible. "Adapters" are actually USB sound cards.

    The bull was quite large. Fact. Now, when I read it, I see an error. I forgot about the analog signal, I only thought about the connection.

    It is correct.

    Different size, different shape, different contacts. Can't be done.

  • Need to specify the exact plug and device

Topic summary

LABEL_AI_GENERATED
The discussion concludes that a passive 3.5 mm jack to USB microphone adapter cannot be made by directly wiring pins together, because the laptop’s USB port and the analog microphone jack use different signal types and contacts. Several replies explain that such “adapters” are actually USB sound cards with internal electronics, not simple 1:1 connectors. A ready-made USB audio adapter or external USB sound card is suggested as the practical solution.
