We made an inventory of the classic PC designs in Apple's history a few days ago, and its colorful candy colored shell won praise from users, The popularity of Mac has also become the stepping stone of Apple's re emergence. Under the leadership of Jobs, Apple launched another landmark product line in Apple's history - iPod, which has changed the pattern of digital music and even the entire record market since then. Although the first generation iPod is not as beautiful as its predecessor, and only has a monochrome black and white screen, compared with other competitors at that time, its appearance design has been quite amazing. It uses a ring mounted roller disc called iPod Click Whell to operate. This classic design has also been continued in the iPod product line.

One of the most classic is the well-known classic series, and classic 3 is the last product of this series. As the most orthodox pedigree of the iPod, classic can be said to be handed down in one continuous line, continuing the classic appearance design of the old iPod, revealing exquisite manufacturing technology and design aesthetics in the minimalism, and classic3 is also the most representative product of the iPod.

As a portable music device, the larger body of the iPod is somewhat inconsistent with the concept of "Walkman". Therefore, Apple launched the compact iPod mini in 2005, which uses a micro hard disk as the memory, reducing the volume by 69% compared with the iPod, and bringing a colorful anodized aluminum body. The iPod is gradually moving towards a lively, young and energetic route.

Compared with other predecessors who use hard disk as storage medium, the iPod nano with flash memory as the medium is the orthodox successor of the mini series. With the gradual reduction of the cost of flash memory chips, Apple has also begun to use flash memory chips as storage materials, which not only saves more power, but also makes the nano series more compact, which is 62% smaller than the predecessor mini in size, And for the first time, 32768 color screens were added to the mini model.

The appearance of the second generation iPod nano has been slightly improved. Instead of using the acrylic+metal back cover design, it uses an aluminum plated shell, which has improved its durability to a certain extent, and provides users with black, silver, pink, blue, green and other colors to choose from.

The third generation iPod nano is the cutest one in the series, commonly known as "Little Fatty". It is different from its brothers and sisters' slender shape, but has a short and thick body similar to Classic. The short, short, fat and cute shape is popular among users.

After a brief experience with the short and cute nano 3, the nano 4 has returned to its slender figure. The nano 4 basically continues the configuration of the previous generation. The same 2-inch color screen has been changed from horizontal to vertical. The nano 4 provides 8GB/16GB capacity options, as well as pink, red, orange, yellow, green, blue, purple, black and silver body colors, which are quite eye-catching.

The fifth generation nano 5 continues the design of the fourth generation in appearance, but the screen has increased to 2.2 inches, the resolution has also increased to 240 × 376, and a 300000 pixel camera has been added, which can be used to record video with 640 × 480 resolution. Although the appearance and color remain the same as that of Generation 4, the nano 5 is changed from aluminized alloy to polished aluminized, which makes the color more bright.

The iPod nano 6 is the smallest nano family. Compared with the previous generation, The nano 7 has reduced its size by 46%, which is a little larger than the four Shuffles. It is quite small and exquisite, and uses a back clip design similar to Shuffles. It can be transformed into a "nano smart watch" through a customized strap. However, this design only used one generation, and the subsequent nano 7 abandoned this design.

In addition to the classic/mini/nano, don't forget about the compact shuffle series. As a relatively inexpensive iPod option, the whole series of the device is not equipped with a display screen, so it can only perform simple operations, such as sequential play/random play, pause of the next song and other basic operations. The 2nd, 3rd and 4th generation models of this series are all equipped with a back clip design, which can be clipped on clothes, so that users can carry them with them when exercising or outdoors.
