In the application process, when the electronic device is in a call, the ultrasonic fingerprint module 10 can be used for detecting the distance between the head of a person and the display screen. After the call is connected, the receiver 20 can send out 20-40k of ultrasonic signals, meanwhile, the ultrasonic fingerprint module 10 on the upper side close to the receiver 20 can also be started to receive the ultrasonic signals, and when the head of a person is not close to the display screen 30, the ultrasonic fingerprint module 10 below the display screen 30 is limited to receive the ultrasonic signals of the receiver 20; when the people head was close to display screen 30, the people head can reflect the supersound signal of earphone 20, and supersound signal is reflected supersound fingerprint module 10 under the display screen 30, and this moment, supersound signal energy that supersound fingerprint module 10 received increases a lot. Through the difference of the ultrasonic signal energy that supersound fingerprint module 10 received around, can detect the condition that people's head is close to display screen 30, when detecting people's head and being close to display screen 30, when the ultrasonic signal energy that supersound fingerprint module 10 received obviously increased promptly, the inside software of cell-phone can control display screen 30 and rest the screen, reaches the purpose of economizing on electricity. Supersound fingerprint module 10 has fingerprint unblock function, and multiplexing supersound fingerprint module 10 is in order to be used for detecting the distance between people's head and the display screen for detection efficiency is higher. Supersound fingerprint module 10 can detect the condition that people's head is close to display screen 30 when the conversation, does not adopt MIC (microphone) pickup hole to receive supersound mode, need not to pay close attention to the frequency width design of MIC passageway, effectively improves the detection rate, and the usable effective frequency width of supersound is wideer, and sensitivity is higher, and the precision is more accurate, is difficult to the spurious triggering.
The electronic device can be a mobile phone, and when playing games, the ultrasonic fingerprint module 10 can be controlled to acquire the operation information of the finger according to the reflection signal of the received ultrasonic signal. When a user plays a game, the mobile phone is placed in a transverse screen mode, the transverse screen placement of the mobile phone can be detected through a gravity acceleration sensor inside the mobile phone, and when the mobile phone detects that game app enters, the mobile phone can start the ultrasonic fingerprint module 10 to be used as a keyboard. The realization principle is as follows: the supersound fingerprint module 10 of both sides is through detecting the removal of finger on display screen 30, and the fingerprint of finger can reflect the ultrasonic signal that supersound fingerprint module 10 sent, and supersound fingerprint module 10 can detect the mobile state of finger/double click of finger and click the reflection condition to the supersound to detect the mobility control of finger, can regard as keyboard/game paddle to control.
When the mobile phone is in a horizontal screen state and a vertical state, the mobile phone can judge whether to enter a game or not through internal gravity acceleration or whether to enter a game app; when the game is not played, the ultrasonic fingerprint module 10 at the lower part of the mobile phone can be used for unlocking the function; the upper ultrasonic fingerprint module 10 (close to the earpiece 20) may not be turned on for power saving. When a game/keyboard application is required, software can automatically detect whether a game is entered or not by detecting the entry condition of game app and the identification of a sensor inside a mobile phone, so that the ultrasonic fingerprint module 10 is automatically switched to be used for gamepad or keyboard control. In the corresponding area of supersound fingerprint module 10, can be through some software definitions, can increase some control button on the display screen 30 that corresponds it, for example button such as pause, volume add or subtract, these buttons can be realized through the reflection of fingerprint to supersound. When supersound fingerprint module 10 was as keyboard or button, can utilize supersound fingerprint module 10 to adjust loudspeaker volume/close loudspeaker sound production. When the loudspeaker produced sound, can change the energy size that supersound fingerprint module 10 received through manual touch screen, function such as automatic adjustment volume specifically can define through the inside software of cell-phone.
