Description

Method and device for detecting rear cover of mobile terminal and computer readable storage medium

Technical Field

The present invention relates to the field of mobile terminal application technologies, and in particular, to a method and an apparatus for detecting a rear cover of a mobile terminal, and a computer-readable storage medium.

Background

The rear cover is a main protective external surface part of the mobile terminal, the rear cover is less concerned in the prior art, and the rear cover is the longest touch place with the outside at the outermost edge of the mobile terminal in daily use; when the mobile terminal is placed in a bag or a pocket, the rear cover is easy to collide and rub hard objects such as coins and keys. When the mobile terminal falls on the ground, the rear cover collides with the ground and rubs against the ground.

If the user uses a non-standard manufacturer's back cover, because the manufacturer is mimicking the pattern in the standard manufacturer's back cover, the electrical characteristics are likely to be incorrect given that the antenna, wires, etc. are more precise, such as the antennas having 1 mm difference in position, and the performance is much different.

Therefore, the prior art lacks or omits a method related to rear cover identification and detection, and needs to be improved and developed.

Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

Theinput unit 330 may be used to receive input numeric or character information and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, theinput unit 330 may include a touch-sensitive surface 331 as well asother input devices 332. The touch-sensitive surface 331, also referred to as a touch screen or touch pad, may collect touch operations by a user on or near the touch-sensitive surface 331 (e.g., operations by a user on or near the touch-sensitive surface 331 using a finger, a stylus, or any other suitable object or attachment), and drive the corresponding connection device according to a predetermined program. Alternatively, the touchsensitive surface 331 may comprise two parts, a touch detection means and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to theprocessor 380, and can receive and execute commands sent by theprocessor 380. In addition, the touch-sensitive surface 331 may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves. Theinput unit 330 may compriseother input devices 332 in addition to the touchsensitive surface 331. In particular,other input devices 332 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

Thedisplay unit 340 may be used to display information input by or provided to the user and various graphical user interfaces of the mobile terminal 300, which may be made up of graphics, text, icons, video, and any combination thereof. TheDisplay unit 340 may include aDisplay panel 341, and optionally, theDisplay panel 341 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, touch-sensitive surface 331 mayoverlay display panel 341, and when touch-sensitive surface 331 detects a touch operation thereon or thereabout, communicate toprocessor 380 to determine the type of touch event, andprocessor 380 then provides a corresponding visual output ondisplay panel 341 in accordance with the type of touch event. Although in FIG. 5, touch-sensitive surface 331 anddisplay panel 341 are implemented as two separate components for input and output functions, in some embodiments, touch-sensitive surface 331 anddisplay panel 341 may be integrated for input and output functions.

The mobile terminal 300 includes at least onesensor 350, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of thedisplay panel 341 according to the brightness of ambient light, and a proximity sensor that may turn off thedisplay panel 341 and/or the backlight when the mobile terminal 300 is moved to the ear. As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when the mobile phone is stationary, and can be used for applications of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be further configured on the mobile terminal 300, detailed descriptions thereof are omitted.

Audio circuitry 360,speaker 361, andmicrophone 362 may provide an audio interface between a user and the mobile terminal 300. Theaudio circuit 360 may transmit the electrical signal converted from the received audio data to thespeaker 361, and the audio signal is converted by thespeaker 361 and output; on the other hand, themicrophone 362 converts the collected sound signal into an electrical signal, which is received by theaudio circuit 360 and converted into audio data, which is then processed by the audiodata output processor 380 and then transmitted to, for example, another terminal via theRF circuit 310, or the audio data is output to thememory 320 for further processing. Theaudio circuit 360 may also include an earbud jack to provide communication of a peripheral headset with the mobile terminal 300.

The mobile terminal 300, which may assist the user in e-mail, web browsing, streaming media access, etc., through the transmission module 370 (e.g., a Wi-Fi module), provides the user with wireless broadband internet access. Although fig. 5 shows thetransmission module 370, it is understood that it does not belong to the essential constitution of the mobile terminal 300 and may be omitted entirely within the scope not changing the essence of the invention as needed.

Theprocessor 380 is a control center of the mobile terminal 300, connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions of the mobile terminal 300 and processes data by operating or executing software programs and/or modules stored in thememory 320 and calling data stored in thememory 320, thereby integrally monitoring the mobile phone. Optionally,processor 380 may include one or more processing cores; in some embodiments,processor 380 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications.
