Thin Speaker Really Quiet - Do I Need An Amp?

Hey,

I purchased a Thin Speaker ( https://shop.pimoroni.com/products/thin-speaker ) a while back and only got chance to test it. I’ve connected it to a 3.5mm headphone jack and connected it to the Raspberry Pi. The audio out of the speaker is VERY quiet, however. It’s audible if you put the speaker right next to your ear, but other than that you can’t hear it.

Do I need to get some sort of amp for it? And if so, please could you recommend a decent one?

Thank you in advance,
Sam
