Connect speakers to two sources

Question

I want to connect the speakers to two sound sources at the same time. They will reproduce both sources simultaneously or there will be some way to switch between them (like a switch) is not important.

Googled that the simplest (barbaric) method is to simply solder the wires. But I'm not going to solder anything. Can I find a suitable finished device? That is, either just something like a splitter, but on the contrary, or it is the same, but with a switch. No additional frills are needed. By the way, how is such a thing called?

It also occurred to me to use an adapter for combining headphones and a microphone, such as the one in the photo. What will happen if both of its ends are inserted into the sources of sound, and the speakers are inserted into it? Or do you need something else?

@Sergey, I don’t understand electronics at all, I don’t know how to solder, besides there’s nothing.
I want to have a ready posting for an adequate price (and not "the simplest ... mixer for 8K", as it’s googled in one of the forums).
With a primitive connection with cords, two sound sources will be connected to each other, more precisely two electrical circuits.
Not being a radio amateur, I suspect that they can adversely affect each other, and it is better to ask an experienced radio amateur than to rely on a dunn one or a coder, be it an avtaritet for level 100001 windows.
If only switching is necessary, then a paired / built toggle switch (by the number of channels) is sufficient.
For the same amount, you can probably find a cheap multi-channel av-receiver.

If you just "solder" nothing good will come of it.
The output of the final amplifier is sharpened for the periphery of a certain reactive impedance (the output to the speakers is usually 4 Ω, the headphones are about 16 Ω / 32 Ω / 300 Ω).

The mismatch of the output impedance with the load impedance drastically degrades the quality of the amplification, because the output stages of the amplifiers change the mode of operation (up to a failure!). In your case, you need to take into account the mutual influence of sound sources.

You need to decide what you need:

Sound Source Mixer
Sound source switch:

Everything is much simpler with the switch - only one load is working at a time. It can even be included in the opposite direction :)

"The output to the speakers is usually 4 Ω, to the headphones about 16 Ω / 32 Ω" - I did not understand this moment.
3.5 "jacks are usually hung on high-impedance low-power cascades (linear output). 4/8/16 relate to terminal amplifiers and are not relevant to the question. You can read more here: GOST 24838-87. 2.7 Negotiation of speakers with ULF , if interested. =)

A device that can mix 2 or more channels, as well as control their volume, turn off or turn on certain channels in solo mode - is called a mixer.

And if everything that is in "as well as" is not required? As far as I can imagine, a mixer is a rather complicated and expensive device, and only 3 pieces of wire with a switch are interested and nothing more. - Qwertiy ♦
Mass options: If one channel is a computer, the second channel can be plugged into its linear input and the computer itself will mix these 2 channels. If at all simple: Buy a two-way switch in any electric store for 20 rubles. It has 3 contacts, we attach to the first contact plus channel1, to the second (middle) plus that goes to the columns, to the third plus channel2. The second wire from the speakers is grounded to anything. - PressAnyKey
the wire from the headset will not work, since the output will be sound only from the wire on which the earphone is drawn. - PressAnyKey
