In this latest video from our ongoing iPhone Basics series, we investigate the question that seems to forever permeate the iPhone community. Just what is the deal with the iPhone speakers? Why is sound only coming from one speaker?

Likely, you already know the answer to this question, but for new iPhone owners, it’s a legitimate inquiry. Check inside as we spill the beans on the iPhone’s speaker issues, along with a brief history lesson as well…

As you’ll see in the video above, the iPhone 4, and all other versions of the iPhone for that matter only feature one speaker at the bottom of the iPhone. The other “speaker” is actually the phone’s primary microphone.

Interestingly enough, the position of the microphone and the speaker was swapped around for the iPhone 4, so if you’re used to one of the older iPhones, it may take an adjustment for you to get used to the iPhone 4
