ã€Global Science and Technology Report】 Our common headphones not only listen to music, but also can help answer the call. According to the British "Daily Mail" reported on February 7, what is the difference between Apple's patent for headphones?
This patent was filed in May 2011 and gives the following description. When a special sensor is added to the device, the "trumpet mode" is activated when the headset is in a specific position. Therefore, the headset is "dual mode", the user can rotate the earbuds or ear clip 90 ° to complete the free switching of the listening mode and the speaker mode, whether it is in-ear headphones or clip-on headphones are applicable.
In addition to being able to switch freely, the headset has the following highlights. First, there are various kinds of special sensors and their sources are wide. Mechanical flow sensors, photoresist sensors, capacitance sensors, distance sensors, infrared sensors, photometric sensors, and impedance sensors can be applied. Second, the earphone mode design is extremely user-friendly and intelligent in operation. For example, thanks to the distance sensor, the speaker mode is automatically turned off when the earphone is close to the ear. When the ear clip is everted, the sensor switches to speaker mode and automatically raises the volume.
According to Apple internal personnel, this design will also be used for Earpods and Airpods, and may add buttons to allow users to automatically switch modes. (Internship compilation: Wang Xiangyu reviewer: Li Zongze)
