How to repair computer speakers ? They have no screws how to open them ? i tried to pull but nothing?

buy some new ones

They are cheap, buy new ones!

Laptop speakers are tiny, have no segments to separate.  Drop in and screw down, connect the wiring is how to replace them.

External or desktop speakers are usually made quite cheaply.  Few repair parts are available.  You might just spend a few bucks to get new ones.

Mine never break...............

you aren't supposed to open them.

how can you repair them if you can't even get them open without damaging them?

and how are we supposed to know what model yhey are? we are not psychic...

A lot of cheaper ones are just glued together.

Other may have screws under labels or snap-in grilles, so examine those carefully.

If there are no screws anywhere, start working around the casing joints with a sharp knife or metal spudger until they loosen and start to separate...

Which computer?

Get the brand and model number- then google the question- something like this- "how to remove speaker from Asus K-52F".

You'll probably get several hits like that. Try it.

My laptops have screws.  Desktops just pull apart.
