Where can I find small speakers like the ones in smartphones?

The speakers in smartphones are very loud for their size. Where can I find a small one like this? Everything on Amazon or eBay is significantly larger. There are small speakers online but they are no where near as loud as the smartphone ones.

Thanks in advance.

By the way, when researching a related thread (https://www.physicsforums.com/threads/modern-speaker-technology.979639/#post-6254004)

I ran across a comment that said that smart phone designers were also very clever in using the case and the volume inside the case to facilitate sound propagation. So it is more than just buying the component.
