Hello, I have a MacBook, a PC, and an iPhone, all three have a jack output (or input, I'm not sure), anyway, a hole where you plug in a jack. I also have a 2.1 Harman/Kardon speaker kit.

What I would like is for the sound from these three devices to come through the speakers without having to plug/unplug each time.

I wanted to know what's best, to connect them all at once or alternately?

What method should I use?

How much will it cost?

I also wanted to ask you what a jack output is and what an input is; is the hole the input or is the hole the output?

Best regards.
Configuration: Windows 7 Internet Explorer 7.0

Oula I don’t know, I'm not very familiar with it, these are the Harman/Kardon 2.1 SoundSticks II.

So, a little lesson ^^ outputs are made to go outside of the device. Inputs are made to go inside ^^ you can guess that everything that is a player (mp3, ipod, ...) is equipped with audio outputs because you want the sound from this device to "go" to something else. On the other hand, systems (HI-FI, home cinema...) are equipped with inputs because you want the sound to "come in". Do you understand?

Then, you have products that have both, inputs and outputs. So how do you tell the difference? ^^ Well, the inputs are often colored red and white and labeled "in" while the outputs are labeled "out". This means that if you have a TV, for example, with these jacks, the jacks labeled "in" mean that you want the sound from your device (player or other) to enter the TV, so the TV serves as a sound system, and the jacks labeled "out" are meant to send, so to speak, the sound from the TV to the outside. These are the jacks, you can imagine, that are most used, because they are used to get, for example, the sound from the TV to the HI-FI system (that you will connect to the "in" of the system, if you understood correctly ^^)

Thank you, but isn't there simply an amplifier or a switch or something simpler?

As Julien points out, I don't know if the Jack triplets exist. Otherwise, how many audio inputs does your kit 2.1 have? Describe the connections on top.

Just a simple small mixer with two inputs.
You connect the two PCs to the two inputs of the mixer and output "out" to your speaker system.
And then you control the sound volume either through the mixer or through your PCs.
A small second-hand mixer costs about 20 euros.

I don't know if there is a kind of jack triplet, but it's easily made.
What you need:
4 male 3.5 mm jack connectors

You just need to take 3 and solder them together (red wire to red, white wire to white). Then, once the first 3 are connected, take the 4th and solder it to that as well, so you'll have 3 jacks for your devices and the 4th will connect to your H.K kit.

If you like DIY projects, you can make a little switch yourself with just 3 switches (which you can find at car stores like Norauto, Leclerc Auto, etc.) along with a nice box (plastic or wood), and with these 3 buttons you'll be able to select the desired audio source or even all at once if you want.

As for the holes you mentioned, they are either inputs or outputs; generally, there will be indications nearby for IN or OUT, with IN referring to input and OUT referring to output.

The difference between the two is that an input is usually found on TVs, amplifiers, or kits like yours; it serves to connect an audio or video source (console, PC, DVD player, etc.).

Audio outputs are found on audio or video sources (console, PC, DVD player, etc.) to ensure that sound or image is received by a device (amplifier, speaker kit, TV, etc.).

PS: Sorry for all these beautiful mistakes.
