iPhone5
Creating an entirely new design meant inventing entirely new technology
When we envisioned the new iPhone, we landed on a remarkably thin and light design. But it’s nearly impossible to make a device so thin and so light without sacrificing features or performance.
We could have taken the easy way out and designed something more reasonable and less remarkable. But we didn’t. If the technology didn’t exist, we invented it. If a component wasn’t small enough, we re-imagined it. If convention was standing in the way, we left it behind. The result is iPhone 5: the thinnest, lightest, fastest iPhone ever.
iPhone 5 is just 7.6 millimeters thin. To make that happen, Apple engineers had to think small, component by component. They created a nano-SIM card, which is 44 percent smaller than a micro-SIM. They also developed a unique cellular solution for iPhone 5. The conventional approach to building LTE into a world phone uses two chips — one for voice, one for data. On iPhone 5, both are on a single chip. The intelligent, reversible Lightning connector is 80 percent smaller than the 30-pin connector. The 8MP iSight camera has even more features - like panorama and dynamic low-light mode - yet it's 25 percent smaller. And the new A6 chip is up to 2x faster than the A5 chip but 22 percent smaller. Even with so much inside, iPhone 5 is 20 percent lighter and 18 percent thinner than iPhone 4S.
It’s our thinnest display ever. And it’s the first of its kind.
Making a thinner, lighter iPhone meant even the display had to be thinner. Apple engineers accomplished that by creating the first Retina display with integrated touch technology. Which means instead of a separate layer of touch electrodes between display pixels, the pixels do double duty — acting as touch-sensing electrodes while displaying the image at the same time. With one less layer between you and what you see on iPhone 5, you experience more clarity than ever before. All on a display that’s 30 percent thinner than before.
iPhone 5 is made with a level of precision
you’d expect from a finely crafted watch-not a smartphone
Look at iPhone 5 and you can’t help but notice the exquisite chamfer surrounding the display. A crystalline diamond cuts this beveled edge. It’s what gives iPhone 5 its distinctive lines. Fitting for a phone so brilliant.
Instead of starting
wih the speaker we started with the ear.
It’s not easy to
create earbud-style headphones that not only feel good in your ears, but also
sit securely in your ears. That’s because everyone’s ears are different. Using
optical scans combined with silicone molding, Apple designers created 3D models
of various ear types to find a common shape across many different people. That
shape led to the unique look of the new Apple EarPods. Unlike traditional
circular earbuds, their design is defined by the geometry of the ear. Which
makes them more comfortable for more people than any other earbud-style
headphones.
They’re more stable and
durable, too. Apple engineers asked more than 600 people to test over 100
iterations of the Apple EarPods. Testers ran on treadmills in extreme heat and
extreme cold. They performed various cardio workouts. They were even asked to
shake their heads side to side, up and down. The result: Apple EarPods provide
stronger protection from sweat and water, and they’re remarkably stable in the
ear. Which means they stay in, even when you’re on the go.
It’s not just
about comfort. It’s also about acoustics.
At the same time
Apple designers were trying to define an ideal earbud shape, Apple sound
engineers — acousticians — were focused on improving sound quality. First, they
established a target sound for the Apple EarPods. That target: a person sitting
in a room listening to high-quality speakers.
The biggest determinant of what you hear from any speaker is the
movement of its diaphragm. The inward and outward motion is what creates sound.
But earbud speaker diaphragms are typically made from a single material, which
can limit sound output.
So Apple acousticians re-engineered an earbud speaker diaphragm
with both rigid and flexible materials to minimize sound loss and maximize
sound output. Adding to the superior audio quality are strategically placed
acoustic vents. The most notable of these vents is the one located in the stem
of each EarPod. It allows air inside the stem, which acts as an acoustic
chamber, to flow out. So you hear deeper, richer bass tones. The overall audio
quality of Apple EarPods is so impressive, they rival high-end headphones that
cost hundreds of dollars more.
The thought and
consideration we put into our products go well beyond design.
How a product looks
and performs matters, but so does its impact on the environment. That’s why
nearly every Apple product is made from highly recyclable materials like
aluminum, and why we refuse to use harmful toxins in our components.
Every iPhone starting
with iPhone 3GS is free of brominated flame retardants (BFRs) and polyvinyl
chloride (PVC). That includes our newest iPhone — iPhone 5. In fact, Apple
has one of the strictest BFR-free and PVC-free standards in the industry. And
we expect the same from our suppliers. We go so far as to disassemble our
products into individual components and materials in our Cupertino lab. Then we
test them using many methods, including X-ray fluorescence spectroscopy and ion
chromatography. We do this to ensure that every product we release meets our
environmental standards.
