Adding simple (one button) Audio player using Custom Fields?

Could you please help me finding a way to adding a simple audio player to my posts using Custom Fields. The player will only have Play functionality and nothing more needed.

The use case is in some Learning website which publish new vocabularies and each vocabulary should have Pronunciation. The final result would be something like this image

Now, I worked with Custom Fields and I know how to get back custom field values. The problem is I don’t know how I can show that in this simple context for audio playing.

Thanks in advance.
