The memory can be used for storing software programs and modules, and the processor executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory. The memory can mainly comprise a program storage area and a data storage area, wherein the program storage area can store an operating system, application programs (such as a sound playing function and an image playing function) required by at least one function and the like; the storage data area may store data (e.g., audio data, a phonebook, etc.) created according to the use of the cellular phone, etc. Further, the memory 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.

The input unit may be used to receive input numeric or character information and generate key signals related to user settings and function control of the cellular phone. Specifically, the input unit may include a touch panel and other input devices. The touch panel, also called a touch screen, may collect touch operations of a user (for example, operations of the user on or near the touch panel using any suitable object or accessory such as a finger, a stylus, etc.) and drive the corresponding connection device according to a preset program. Alternatively, the touch panel may include two parts of a touch detection device 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 detection device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor, and can receive and execute commands sent by the processor. In addition, the touch panel may be implemented in various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit may include other input devices in addition to the touch panel.

In addition, the handset may also include at least one sensor, such as an attitude sensor, a light sensor, and other sensors.

Specifically, the attitude sensor may also be referred to as a motion sensor, and as one of the motion sensors, a gravity sensor may be cited, which uses an elastic sensing element to make a cantilever-type displacer and uses an energy storage spring made of the elastic sensing element to drive an electrical contact, thereby realizing conversion of a change in gravity into a change in an electrical signal.

Another example of the motion sensor is an accelerometer sensor, which can detect the magnitude of acceleration in each direction (generally, three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications for recognizing the posture of a 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.

In the embodiment of the present invention, the motion sensor listed above may be used as an element for obtaining the "attitude parameter" described later, but the present invention is not limited thereto, and other sensors capable of obtaining the "attitude parameter" fall within the protection scope of the present invention, for example, a gyroscope, etc., and the operation principle and the data processing procedure of the gyroscope may be similar to those of the prior art, and the detailed description thereof is omitted here for avoiding redundancy.

In addition, in the embodiment of the present invention, as the sensor, other sensors such as a barometer, a hygrometer, a thermometer, and an infrared sensor may be further configured, which are not described herein again.

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 mobile phone is moved to the ear.

The audio circuitry, speaker and microphone may provide an audio interface between the user and the handset. The audio circuit can transmit the electric signal converted from the received audio data to the loudspeaker, and the electric signal is converted into a sound signal by the loudspeaker to be output; on the other hand, the microphone converts the collected sound signal into an electric signal, the electric signal is received by the audio circuit and then converted into audio data, and the audio data is processed by the audio data output processor and then sent to another mobile phone through the radio frequency circuit or output to the memory for further processing.

WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through a WiFi module, and provides wireless broadband internet access for the user. The processor is a control center of the mobile phone, is connected with each part of the whole mobile phone by various interfaces and lines, and executes various functions and processes data of the mobile phone by running or executing software programs and/or modules stored in the memory and calling the data stored in the memory, thereby carrying out the integral monitoring on the mobile phone. Alternatively, a processor may include one or more processing units; preferably, the processor may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.

It will be appreciated that the modem processor described above may not be integrated into the processor.

Also, the processor may perform the same or similar functions as the processing unit as the implementation elements of the processing unit.

The handset also includes a power source (such as a battery) to power the various components.

Preferably, the power supply may be logically connected to the processor through a power management system, so that functions of managing charging, discharging, power consumption management, and the like are realized through the power management system.
