What a Microphone Does. Dynamic Microphones | Condenser Microphones | Phantom Power | Other Types of Microphones. Like phono cartridges, headphones and loudspeakers, the microphone is a transducer in other words, an energy converter. It senses acoustic energy (sound) and translates it into equivalent electrical energy.
Only these two components are exclusive to the iPhone X. So technically, it only costs $105 ($80+$25) more to build the iPhone X while compared to the other regular models, yet their prices differ by over $200. The 3GB RAM that is also present on the iPhone 8 Plus doesnât come cheap either ($24).
Since the iPhone X starts at $999, Â£999 and AU$1,579, this estimate puts Apple's profit at a gross margin of 64 percent. The iPhone 8-- which costs $699, Â£699 and AU$1,079 to buy -- reaps in a gross margin of 59 percent, according to the report.
