The casing 10 is a middle frame or a battery cover of the electronic device 100, and is used for carrying a circuit board, a display screen, various electronic devices, and the like. In this application, a first through groove 12 is formed in the housing 10, and the first through groove 12 is used for arranging the camera assembly 20 and the sensor assembly 30. The glass cover 101 is provided with a light-transmitting portion 102, and as shown in fig. 4, the light-transmitting portion 102 is a position where ink is not applied and through which light passes.

It is to be understood that the terms "first" and "second" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature. The camera 21 includes a base 22 and a lens assembly 24 connected to the base 22, and a portion of the first flexible printed circuit board 50 is disposed in the base 22 for transmitting picture information captured by the lens assembly 20 to the circuit board. Specifically, the base 22 is further provided with an image sensor and the like, which is not described in detail. The lens assembly 24 includes a plurality of optical lenses, an infrared filter, and the like, and is used to take a picture.

The sensor assembly 30 comprises a second flexible printed circuit board 31 and a sensor 40 fixed on the second flexible printed circuit board 31, wherein the second flexible printed circuit board 31 is fixedly connected to the camera assembly 20 and is connected with the circuit main board so as to transmit the information collected by the sensor 40 to the circuit main board. It is understood that the sensor 40 and the camera 21 in the present application are connected to the circuit board through different flexible printed circuit boards. The sensor 40 is fixed on the second flexible printed circuit board 31 such that the sensor 40 and the camera assembly 20 are integrated through the second flexible printed circuit board 31, and the sensor 40 transmits or receives external light through the first through groove 12.

Further, in an embodiment, a projection of the sensor 40 in a direction perpendicular to the housing 10 at least partially overlaps the base 22, so that the sensor 40 is integrated with the camera 21 to a higher degree and occupies a smaller space. Specifically, the sensor 40 may include only one of the proximity device 42 and the light-sensing element 44, or may be a combined assembly including two or three of the proximity device 42 and the light-sensing element 44, as further described below with reference to various embodiments.

In the embodiment in which the sensor 40 comprises the proximity device 42, the working principle of the electronic device 100 with the above solution is explained below. The functions realized by the scheme at least comprise: when the electronic device 100 is in use, the screen and the use scene of the user are matched, so that the screen of the display screen is turned off when the user answers the phone, after the screen of the display screen is turned off, the light emitted by the sensor 40 passes through the first through groove 12 and the glass cover plate 101, and whether the display screen is in a non-phone answering state or not and whether the display screen needs to be turned on or not is judged according to the received reflected light.

Specifically, when the user uses the electronic device 100 to place the electronic device 100 at the ear for a call, the screen of the electronic device 100 is close to or contacts the ear or the face, so that the capacitance value in the display screen changes, and when the capacitance value is within the preset range, it indicates that the user is using the electronic device 100 for a call to perform a screen-off operation. It can be understood that when the electronic device 100 is close to the ear and the face, the area of the whole screen close to the face or the ear is relatively large, and when the user is listening to a phone call with an earphone or hands-free, if the user only uses a finger to approach or touch the screen to perform other operations besides a call, since the area of the finger approaching or touching the screen is significantly smaller than the area of the face or the ear approaching or touching the display screen when the user holds the electronic device 100 to talk at the ear, the capacitance value in the display screen is in different ranges in the above two cases. Therefore, the screen can be actively turned off only when the user answers the phone by holding the electronic device 100, and the screen can not be turned off when the user touches the screen to perform other operations in other states, such as answering the phone as described above.

And after the screen of putting out appears in the display screen, sensor 40 can constantly send light under the time interval that predetermines, this light is infrared light, infrared light passes first logical groove 12 and glass apron 101 in proper order, when the user is using electronic device 100 to converse, the infrared light that sensor 40 sent is beaten on user's ear, perhaps on the face, perhaps on the head, then infrared light reflection loops through glass apron again and transmits to sensor 40 on, sensor 40 judges whether present user handheld electronic device 100 converses in the ear according to the SNR of received infrared light. Because the display screen is in close proximity to the user's face or ear while the user is holding the electronic device 100 in the ear, the signal-to-noise ratio of the infrared light reflected back is different from the signal-to-noise ratio of the infrared light received when the electronic device 100 has moved away from the user's ear or face. Therefore, on the premise of implementing the screen-off according to the change of the capacitance value of the display screen, the operation of turning on the screen is performed by continuously emitting infrared rays and judging whether the electronic device 100 has left the ear or the face of the user according to the signal-to-noise ratio formed by the infrared rays received after the emission.

In the embodiment where the sensor 40 includes the light sensing element 44, the light sensing element 44 receives the ambient light outside the cover glass 101, so that the display screen can adjust the brightness of the display screen according to the ambient light sensed by the light sensing element 44. When the user uses the electronic device 100, the situation that the display screen is dark, the user cannot see the picture on the display screen clearly, or the user needs to feel hard to see the picture on the display screen clearly under the condition that the ambient light is bright is avoided; and the condition that the display screen is abnormally bright to make a user feel dazzling when the ambient light is dark is avoided.

In other embodiments, the housing 242 may be made in other shapes, such as a cylinder, a rectangular parallelepiped, etc., and is not limited in this respect.

In another embodiment, an adhesive layer (not shown) is disposed between the inner wall of the second through groove 32 and the outer wall of the lens assembly 24, that is, between the inner wall of the second through groove 32 and the outer wall of the housing 242.
