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 in the mobile terminal 100, detailed descriptions thereof are omitted.

Audio circuitry 160, speaker 161, and microphone 162 may provide an audio interface between a user and mobile terminal 100. The audio circuit 160 may transmit the electrical signal converted from the received audio data to the speaker 161, and convert the electrical signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signal into an electric signal, converts the electric signal into audio data after being received by the audio circuit 160, and then outputs the audio data to the processor 180 for processing, and then to the RF circuit 110 to be transmitted to, for example, another terminal, or outputs the audio data to the memory 120 for further processing. The audio circuit 160 may also include an earbud jack to provide communication of a peripheral headset with the mobile terminal 100.

The mobile terminal 100, which can assist the user in receiving requests, transmitting information, etc., through the transmission module 170 (e.g., Wi-Fi module), provides the user with wireless broadband internet access. Although the transmission module 170 is shown in the drawings, it is understood that it does not belong to the essential constitution of the mobile terminal 100 and may be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 180 is a control center of the mobile terminal 100, connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions of the mobile terminal 100 and processes data by operating or executing software programs and/or modules stored in the memory 120 and calling data stored in the memory 120, thereby integrally monitoring the mobile terminal. Optionally, processor 180 may include one or more processing cores; in some embodiments, the processor 180 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 180.

The mobile terminal 100 may also include a power supply 190 (e.g., a battery) for powering the various components, which may be logically coupled to the processor 180 via a power management system that may be used to manage charging, discharging, and power consumption management functions in some embodiments. The power supply 190 may also include any component including one or more of a dc or ac power source, a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator, and the like.

Although not shown, the mobile terminal 100 further includes a camera (e.g., a front camera, a rear camera, etc.), a bluetooth module, a flashlight, etc., which will not be described herein. Specifically, in the present embodiment, the display unit of the mobile terminal 100 is a touch screen display.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalents or equivalent substitutions fall within the protection scope of the claims of the present invention.

In summary, although the preferred embodiments of the present invention have been described above, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
