How can a cell phone (Razor Phone, S9 Galaxy) advertise 80+dba?

How are they achieving this with a small speaker? :eek:

Asking is for my project. I need a speaker that is micro size.

Less than 1.5" wide X 1.5" tall X .5" deep

This is for a video intercom, so voice only, no heavy bass necessary.

I want to get 90+dba for super loud compact intercom.

Please help me locate speaker. Alibaba, ebay all good. ;)

These tiny speakers are often measured at a distance of 10cm:D
