The small hole next to the iphone13 camera is a microphone, which adopts a dual-mark noise reduction design. It is used to assist the secondary microphone to collect sound. It can be used to reduce environmental noise and improve the clarity of call speech. Since the subject's sound reception is poor due to environmental noise when shooting video, most smartphones are currently equipped with multiple noise reduction microphones on the body to record the noise of the surrounding environment, combined with noise reduction. Algorithm to achieve noise reduction effect.

The small hole next to the iphone13 camera is a microphone. It adopts a double-mark noise reduction design. It is used to assist the secondary microphone to collect sound. It can be used to reduce environmental noise and improve the clarity of the call voice; generally the outer layer There is a mesh protective net to prevent dust from entering. Since the subject's sound reception is poor due to environmental noise when shooting video, most smartphones are currently equipped with multiple noise reduction microphones on the body to record the noise of the surrounding environment, combined with noise reduction. Algorithm to achieve noise reduction effect.
iPhone 13 is an iPhone phone released by Apple in the United States at Apple Park at 1 am on September 15, 2021, Beijing time.
iPhone 13 uses a 6.1-inch OLED screen; height is about 146.7 mm, width is about 71.5 mm, thickness is about 7.65 mm, weight is about 173 grams; available in red, starlight, midnight, blue, pink, green Six colors.
The iPhone 13 is equipped with the A15 Bionic chip, which is based on a 5-nanometer design and has improved performance and energy efficiency. The A15 Bionic CPU has a 50% performance improvement. Graphics performance has a 30% performance improvement. With the 16-core neural network engine, machine learning capabilities can also be achieved.
The iPhone 13 uses a 12-megapixel front camera with a 2.4nm aperture and a 120-degree wide angle. It supports 4k60-frame HDR shooting, movie effect mode and low-light shooting. The rear uses a 12-megapixel wide-angle lens and a 12-megapixel ultra-wide-angle lens, which supports 2x optical zoom and 5x digital zoom. The wide-angle lens supports sensor-shift optical image stabilization and other functions.
The operating ambient temperature of iPhone 13 is 0 degrees Celsius to 35 degrees Celsius (32 degrees Fahrenheit to 95 degrees Fahrenheit), and the non-operating temperature is −20 degrees Celsius to 45 degrees Celsius (−4 degrees Fahrenheit to 113 degrees Fahrenheit), Relative humidity is 5% to 95% in non-condensing conditions, and operating altitudes are tested up to 3,000 meters (10,000 feet).
Appearance features
Dimensions and weight
The height of iPhone 13 is approximately 146.7 mm, and the width is approximately It is 71.5 mm, the thickness is about 7.65 mm, and the weight is about 173 grams.
Body design
The appearance design of iPhone 13 is by moving the earpiece upward. The successful reduction of bangs not only brings about a further improvement in the screen-to-body ratio, but also represents a further upgrade in the Face ID area.
On the front of the iPhone 13, the Face ID area integrates a microphone, speaker, front camera, ambient light sensor, proximity sensor, infrared lens, flood illuminator, and dot matrix projection devices and other components. Reduce bangs by 20%.
The dual-camera lens on the back of the iPhone 13 adopts a diagonal design. This design is to reserve more space for the battery. At the same time, the iPhone 13 uses an XDR screen on the front, with a screen brightness of 800 nits and a peak brightness of 1,200 nits in HDR mode.
