The memory 502 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the terminal device 20, and the like. Further, the memory 502 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device. Accordingly, the memory 502 may also include a memory controller to provide the processor 508 and the input unit 503 access to the memory 502.

The input unit 503 may be used to receive input numbers, character information, or user characteristic information (such as a fingerprint), and generate a keyboard, mouse, joystick, optical, or trackball signal input related to user setting and function control. In particular, in one particular embodiment, the input unit 503 may include a touch-sensitive surface as well as other input devices. The touch-sensitive surface, also referred to as a touch display screen or a touch pad, may collect touch operations by a user (e.g., operations by a user on or near the touch-sensitive surface using a finger, a stylus, or any other suitable object or attachment) thereon or nearby, and drive the corresponding connection device according to a predetermined program. Alternatively, the touch sensitive surface 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 the processor 508, and can receive and execute commands sent by the processor 508.

The display unit 504 may be used to display information input by or provided to the user and various graphical user interfaces of the terminal device 20, which may be made up of graphics, text, icons, video, and any combination thereof. The display unit 504 may include a display panel. Alternatively, the Display panel may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch-sensitive surface may overlay the display panel, and when a touch operation is detected on or near the touch-sensitive surface, the touch operation is transmitted to the processor 508 to determine the type of touch event, and then the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in FIG. 18 the touch sensitive surface and the display panel are two separate components to implement input and output functions, in some embodiments the touch sensitive surface may be integrated with the display panel to implement input and output functions. It is understood that the display screen may include an input unit 503 and a display unit 504.

The terminal device 20 may also include at least one sensor 505, such as light sensors, motion sensors, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel according to the brightness of ambient light, and a proximity sensor that turns off the display panel and/or the backlight when the terminal device 20 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 can be configured on the terminal device 20, detailed description thereof is omitted.

Audio circuitry 506 may provide an audio interface between the user and terminal device 20 through a speaker, microphone. The audio circuit 506 can convert the received audio data into an electrical signal, transmit the electrical signal to a speaker, and convert the electrical signal into a sound signal to output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and converted into audio data, and the audio data is processed by the audio data output processor 508, and then sent to another terminal device 20 through the rf circuit 501, or the audio data is output to the memory 502 for further processing. Audio circuitry 506 may also include an earphone jack to provide communication of a peripheral earphone with terminal device 20.

Wireless fidelity (WiFi) belongs to short-range wireless transmission technology, and the terminal device 20 can help the user send and receive e-mail, browse web pages, access streaming media and the like through the wireless fidelity module 507, and provides wireless broadband internet access for the user. Although fig. 18 shows the wireless fidelity module 507, it is understood that it does not belong to the essential constitution of the terminal device 20, and may be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 508 is a control center of the terminal device 20 and may be sometimes referred to as a main controller, and the processor 508 connects various parts of the entire terminal device 20 by using various interfaces and lines, and performs various functions of the terminal device 20 and processes data by running or executing an application program stored in the memory 502 and calling data stored in the memory 502, thereby performing overall monitoring of the terminal device 20. Optionally, processor 508 may include one or more processing cores; alternatively, the processor 508 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 508.

The terminal device 20 also includes a power supply 509 to supply power to the various components. Preferably, the power supply 509 may be logically connected to the processor 508 through a power management system, so that the power management system may manage charging, discharging, and power consumption. The power supply 509 may also include any component such as one or more dc or ac power sources, recharging systems, power failure detection circuitry, power converters or inverters, power status indicators, and the like.

Although not shown in fig. 18, the terminal device 20 may further include a bluetooth module or the like, which is not described in detail herein. In specific implementation, the above modules may be implemented as independent entities, or may be combined arbitrarily to be implemented as the same or several entities, and specific implementation of the above modules may refer to the foregoing method embodiments, which are not described herein again.
