Search for 5mm Jack in Topics

Hello, I am trying to connect a 3.5mm jack to a speaker I salvaged from an old radio. The speaker has 2 wires: A + wire (marked yellow) A - wire (marked black) The problem is, the 3.5mm jack has 4 different wires: on one side, there is a copper one and a red one on the other, there is a copper one and a blue one. I got the speaker to work for a few seconds while plugged into my phone, but I cannot remember how it went.

If anyone knows a way to do this it would be a great help.

I have a 3.5mm audio jack on a PCB.  I want to split the signal to go to two different places on a PCB.  Do I need a diode on each "branch" or literally just split them in a T with no components in between?

I want to make it to use it as a Mic.

I'm makeing some speakers for my iphone and i want to know how to make the speakers with a female 3.5mm jack (from computer) instead of a male one

I've got a lot of earphone speakers from cheap giveaways ,and other peoples smashed earbuds. Can anybody think of something cool to do with them?

I want to build an in-line pre-amplifier with a 3.5mm in and out jack.  What I want, or at least think I want, is a simple booster that provides a small, but relatively even gain boost from an MP3 player into the main amplifier. Something along the lines of this: https://www.instructables.com/id/In-line-headphone-amplifier/ However, I would like to be able to power it off of 5V USB or off of the 12V coming into the cigar lighter. What I'm effectively trying to do is get enough gain on low volume spoken-word audio coming out of my mp3 player so that I don't have to crank the stereo up to max.  Does anyone have any good sources for instructions or advice for this sort of thing? Alternatively, someone can tell me if this is a fools errand to begin with, and that I aught to be taking a different approach altogether.

Hey guys! This is my first post, so thanks for any suggestions or ideas! :) So......I do computer repair and tutoring on the side and I just gave my 3.5mm to 3.5mm audio cable that I use for my MP3 player in my car to a client so she could get the speakers in her monitor working on her new PC because it didn't come with the cable and it's Sunday, so all the stores are closed....she needed one to Skype with her daughter and grandkids tonight in France (we're in Canada) and I knew it would mean a lot to her. Being the tinkerer that I am, I thought..."I could buy a cable from the Dollar Store tomorrow for about $3 that will work, or I have enough stuff laying around to just make one..." So, I just made one out of 2 old, non-working sets of headphones by stripping the wires and soldering the 3.5mm jacks together. Both cables have red and white wires, so I assume white is left on both leads and red is right on both leads and solder red/red, white/white, and ground/ground. As far as I can tell, this should be fine! I've double-checked and my solder joints are strong and none of the wires are touching other wires they shouldn't be as far as I can see. However, when I test them in my car with a 30-sec MP3 clip that plays sound through Both channels, then only the Left, then only the Right, I hear sound from all speakers during the "Both" test, NO sound from ANY speakers during the 'Left' test, and all sound from all speakers during the 'Right' test....what did I do wrong? Cheers and thanks! :)

Please tell me how to make a converter(without any purchases) so that i can connect my 3.5 mm jack headphones to my phones mini usb port which is 2 in one charger and audio out port My phone-htc touch  i thought out of something like this http://cdn103.iofferphoto.com/img/item/517/567/639/kMol2in1-3-5mm-headphone-adapter-for-htc-11-pin-mini-usb.jpg thank you in advance

How to I get my stereo to display AUX? (like this: http://www.higherground4x4.com/Tech/Aux-in/P1070081.JPG)  I have that exact same stereo. Is there some button combination or something? (<-- Please be something like this. =P) I know in the guide he uses a switch on the aux cable to turn it on, but I really dont want to (and can't really) do that I'm thinking of buying this, but I'm pretty sure that I need to turn aux on for it to play.  (or will the cable below work without a switch?) http://www.ebay.com/itm/NISSAN-3-5MM-MP3-iPOD-AUX-INPUT-JACK-8-PIN-M-BUS-CABLE-/200535575261?pt=Car_Audio_Video&vxp;=mtr&hash;=item2eb0da0add#ht_1869wt_1165

Hey guys, I have started to do a little project for myself to convert my PC case. While everything was going nice and smooth I decided to look for cool audio jacks for front panel. Now the problem became when I couldnt find anything cool. And so i was wondering is it possible to solder the jacks somehow to be used on a motherboard pins. Was thinking to use something like:  http://www.ebay.co.uk/itm/2-x-3-5mm-Mini-Stereo-Jack-Chassis-Panel-Mount-Headphone-Input-Socket-Connector/361451740585?_trksid=p2385738.c100677.m4598&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20160908110712%26meid%3D1f134081ba3e461ab61500c43348c0d0%26pid%3D100677%26rk%3D7%26rkt%3D18%26sd%3D322058304419 . Any ideas, instructions are more than welcome! Thanks in advance! Regards, Arnold

I want an adapter that merges the microphone and earphone 3.5 mm jacks into a single 3.5 mm jack ( basically I want to build the blue adapter thingy). The problem is how do I connect the  microphone pins from the 3.5mm jack? That is how do I connect the two leads marked "?" (see the third picture for what I want to achieve.) PS: I am not sure whether the microphone jack pinout is the same as drawn. Anybody can confirm whether this is right?

I Need to add a 3.5mm headphone jack to my gaming chair before the release of Final Fantasy 13 in march. problem is i have know idea how to do it the way i want. this is what i want. add the jack so i can use headphones with my chair, but still use the volume dial on the chair and for it to mute the chair speakers when i plug the headphones in. it don't matter if i have to leave the speakers unplugged as long as i can still use the volume dial. please use my picture as a wiring guide. Thanx guys for any help.

I would like to use a Turtle Beach HPA2 headset for my Xbox 360 for true 5.1 sound.  However, it is configured for PC usage and needs some extra stuff to work with a console.  I have everything sourced except for a way to hook up the microphone.  You can purchase a SteelCity Xbox Headset Connector but that seems like a waste of money if a cheap adapter will do.  It seems like you can use the existing HPA2 microphone cord with 3.5mm TRS/mini-stereo jack (I'm assuming it's mono, but it could be stereo), attach it to a 2.5mm reducer, and then plug it into the Xbox controller.  The existing Microsoft headset has a stereo jack, but that's because it has headphones as well and needs a separate channel for that.  I'm not sure how the two (mono) or three (stereo) conductors are situated on both the Xbox socket and the HPA2 plug.  I would assume the HPA2 microphone plug would be standard, but I'm thinking that the Xbox headset is unusual/proprietary as both the sound output and sound input are transmitted through one cord/plug as opposed to two for most PC headsets. http://en.wikipedia.org/wiki/TRS_connector https://www.instructables.com/id/Use-your-awesome-PC-Gaming-Headset-with-an-X-Box/

I was cleaning in the office I work in and found these two devices on the picture. Now I'm curious what are these for as I couldn't derive the purpose from the looks. One of them has a mono 3.5mm audio jack and two LEDs or similar looking parts - 5mm round transparent things. One side of the enclosure around each "LED" has a sticky tape. If they would be attached to something then the "LED" would face 45 degrees from the surface. The other has a stereo 2.5 mm audio jack and one dark IR-reciver-like thing in a small round enclosure. The enclosure has two small holes on the other side, but I'm not sure if they are important. I tried the one with two "LED"-s in a headphone socket but nothing happened.

hello folks, my son keeps bending the wires of all his headphones, causing them to start cutting out in either one or both channels (and now he has done it on one of my nice sets of headphones).  i was wondering if anyone could recommend a place where i can buy them in quantity.  my other question is whether there have been any improvements made in the ease of soldering.  i would think that so many headphones go bad at the jack, probably by pulling, that someone would have invented an "easy-solder" jack.  given that isn't the case, maybe a recommendation could be made on at least a sturdy plug with some sort of stress relief built in?  the large quarter inch stereo plugs used to come with spring coils. thanks for any suggestion, recommendations, comments, etc!

I am working on a voice transmission project by using Spartan 3e. My code works just fine. My problem is that i give analogue input to adc side by using a potentiometer and see the changes (as digital) on leds ( digital output is assigned to leds). Here is the problem, i cut a headphone into two and connected 3.5mm jack side to my phone to play music. There are 3 cable which are golden, blue and red. Golden one is connected to "GND" pin , Red one goes to "Va" pin (at adc input). i didnt touch the blue one. When i play music, i see no change on leds despite the fact that i did see by using potentiometer. What am i missing ? Do i have to setup an external circuit before giving the analog signal to Va input ? Thanks in advance.

I have got a pair of Sony MDR-1R headphones and a pair or Sennheiser MM30i earbuds, both featuring an in-line remote and mic.  The question I have is: does anybody know if there are some kind of splitters to split the cable in audio and microphone jacks to plug in my laptop? I'd like to use the mic on the cable, rather than the one built in my computer or, worse, wearing skype headphones just to pick up a call.. Thanks in advance!

So, here's the color organ (video form) I'm using (or going to use). I was wondering, since the input is from a 3.5 mm audio jack, could I take a direct line from a speaker instead of the jack. I want to use the speaker from this pig and have it as the direct input. Would that work? Would I have to bypass the amplifier in the color organ? All I want is to make the color organ work with the pig, but have the music playing from my iPod on the doc in the pig. (Or maybe the iPod dock might have the same output as a standard 3.5mm jack and I could split it). I am also thinking of buying two kits, one for each speaker, so that I can have the left and right LEDs flash independently. Please help!

I'm new to electronics but in love with it and I have looked around, my cat tends to chew wires, so I wanted to make it easy to replace just the wire in case it happens again. I want to make a mic circuit without the use of IC's but I do have a 555 timer on hand if absolutely necessary. It doesn't have to be stereo because I am new to the hobby and can work with just the single mic at first and learn to upgrade it later. Any help in this would be great because I can't find a simple circuit to accomplish my needs here. I need a mic for my computer and I decided I'd learn more by building one than I would by purchasing one.

Hi, I am working with a Flyron FN-M16 MP3 player module which has both output for headphones (pins 4,5, and GND = 7), and a 3-watt amplifier for speakers (pins 6 & 8).  The problem I am having is that I am unsure of how to disconnect power to the speakers when headphones are plugged into the jack.  This is easy when you have a separate amplifier circuit, but here the amplifier is built in. The easiest solution would be to find an audio jack with an isolated NC (normally closed switch) to disconnect the speakers.  They do not seem to make them in SMD packages.  I have found a 3.5mm stereo audio jack with an isolated NO (normally open) switch from Technik.HK.  Is there a mosfet type circuit that I can use to disconnect the speakers when the NO switch is closed without introducing any distortion to the speaker sound?  Any advice for an electronic disconnect?    P.S:  The manufacturer has stated that if I ground the speaker outputs for the 3-watt speakers I will blow out the internal amplifier on the flyron Mp3 player board.

Hi, I'm doing an A Level project at College, and I'm making an MP3/iPod speaker system. I'm using a 3.5mm headphone jack to connect my iPod to my speaker. I followed these instructions to wire my headphone jack to my speaker, and it worked!: https://www.instructables.com/id/How-to-wire-a-headphone-jack-to-a-speaker/ However, I want it to be a little louder, and it mentioned using an amplifier between the speaker and the headphone wire. Also I want to use a 9v battery to power my speaker, instead of using my iPod battery. I'm new to electronics. I've got a 6 ohm, 6-10watt speaker. I searched for a cheap amplifier at Maplins, and I've found a 1watt ampilifer kit, would that be ok, would it be enough to boost the volume a little? The reason why I have to buy a cheap one is because I need to stay on a low budget (specification related). So how would I wire/connect the headphone jack, the amplifier, the 9v battery connector and the speaker into one circuit? This is the 1watt amplifier I have found: http://www.maplin.co.uk/Module.aspx?ModuleNo=220054 Thanks for reading, and I hope you'll be able to help me :) -Mason

Iam wondering if I could get two walkie talkies (2 way radios but I prefer calling it walkie talkie) and add two 3.5mm jacks one for ear phones and one for a mic.  Using a splitter 3.5mm for the sockets, a 3.5mm mic and a 1m extension  for the mic so I can put the walkie talkie in a pocket. Can someone tell me if this will work please and any suggestions for improvements to my plan

Heya, I've seen many ideas on how to build FM Transmitters on the web and successfully copied a couple of them. They are generally 2 or 3 transistor circuits which aren't very powerful when used with a small aerial. I've just designed a circuit with 4 transistors (2 of them being a darlington pair). So it's pretty similar to the two I've made just hopefully more powerful! The transistors i intend to use are BC548(b)'s because they're cheap and usable for high frequencies. Due to my really bad paint skills I'll annotate a few things on the schematic. On the left i just meant to show that the mp3 player plugs straight into the 3.5mm jack connected to the 330nf cap (all of the caps in the circuit are ceramic) and on the far right the triangle is the aerial which is connected to the 33nf cap. Thanks very much for reading this. I know that the aerial will be a BIG limiting factor to the range of it, but i wanted to design a more powerful circuit before i bought a new aerial anyway! So please can you leave any feedback. Best regards Sorry, but it's impossible to see the values of the components unless it's viewed in the original size, the only way i can see how to do that is by clicking on the little "i" in the top left of the picture.

I have only a limited amount of resources to utilize in this project. I am still a rookie when it comes to physics, so I decided someone here might help. Please also note that I cannot get any additional material because it is not available locally and Amazon/Ebay don't ship to my address. I currently have the following materials: -A cut headphone's wire with a 3.5mm  output at one end, and three wires (green, blue, golden mixed with green) at the other. -A wire with the colored outputs (which you plug into a TV) at one end, and a 3.5mm output at the other -A 3.5 to 6 mm converter -Standard guitar-to-amp cable I can connect both wires to the computer and guitar, but what connection would there be in between? I don't have 6-3.5mm converter; thats basically the problem.

Hi, its been quite some time since Ive been here. And I still have the same two projects in mind. However, the project im more focused on, is a 32x16 RGB led matrix. Made up of four sections. Im following the project by the two guys over at solderlab.se. They arent very active and speak a different language so their english explanations arent as thorough as Im looking for so I figure id ask the people here :) So, the main questions I have: 1. What kind of material can I use to put the leds on? its like they use thick cardboard or wood. they drill all four holes per led so the legs go through. I want one big board instead of two.  2. What spacing would be good to make it look uniform, yet give enough space to solder?  3. How can I make the 4 controller boards to run it? - They sell them, but they arent cheap. And they dont deliver or sell to the US. So Ill have to make them somehow. I can provide images/part list of what they used.  4. What type of solder/soldering iron would I need? Obviously various temp. But what temps would be safe?  5. What power supply can I use? Ok so, any other info: -They used common anode LED's  -They connect the boards together via ethernet cable.  -They connect the led's together in four sections of 8x16, The anode is connected on each of the 8 rows. And the anodes on all the led's are connected on the 16 rows. If that doesnt make sense, the anodes are connected vertically, and all the cathodes are connected horizontally. -They connect the 48 cathode wires to ribbon cable, that goes to the controller board, same with the anode wires.   -They connect the boards to a Usb to UART connector -Lastly, Part list of one controller board:  HEXFET IRF7314 x4 TLC5940NT x 3 28 Pin IC-Socket 300mil x 4 Resistor SMD 0,25W 1% 10K x 10 Resistor SMD 0,25W 1% 2K2 x 8 Resistor SMD 0,25W 1% 2K x 3 Resistor SMD 0,25W 1% 220R x 2 Resisitor SMD 0,25W 1% 1K x 3 AtMega 328P x 1 74HC138 SMD x 1 Ceramic Capacitor 22pF, 20% x 2 Oscillator 16,0 MHz x 1 Pinheader 2x8 Pitch 2.54mm x 4 Jumper x 3 Pinheader 1x2 Pitch 2,54mm x 7 Modular Jack x 2 Ceramic Capacitor 100N, 20% x 5 Electrolytic Capacitor 680uF x 1 LED 5mm blue x 1 LED 5mm green x 1 Screw terminal 5.08mm x 1 If theres ANY more info required please ask. It said to be as detailed as possible.
