What is the use of the row of holes on the lower left corner of the iPhone 7 without the headphone jack?
|
When the iPhone 7 and iPhone 7 Plus were released, Apple executives said that removing the 3.5mm headphone jack took courage. It was because of the removal of the headphone jack that Apple was able to increase the battery capacity of the iPhone 7 and equip it with a better camera sensor. We can notice that there is a speaker on the right side of the bottom of the iPhone 7, and on the left side of the Lightning interface is a symmetrical opening that is the same as the speaker on the right side . This is not a second speaker. Apple uses the speaker of the handset as the second speaker to achieve stereo sound on the iPhone 7. So what is the use of this row of openings in the lower left corner of the iPhone? After disassembly, it can be found that this row of holes is the "ventilation hole for the air pressure sensor." From the appearance, this is the second speaker, but in fact it is just decoration. In order for the air pressure sensor to work accurately, Apple uses the original headphone jack as a "ventilation hole." This design allows the air pressure sensor to detect changes in altitude. The presence of the air pressure sensor can detect the number of floors the user has climbed.As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
