Iphone SE 2020 Making Random Popping sounds.

I got my Iphone SE 2020 a couple of weeks ago from apple online store.

Since I received the phone it has been making popping sounds randomly.

I'm sure it is the speaker that is doing it.

It happens when its not being used or when it is being used.

It seems to happen more while the speaker is in use though but I could be wrong on that.
