These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0094] It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0095] In subsequent descriptions, the suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of explaining this application, and they have no specific meaning in themselves. Therefore, "module", "component", or "unit" can be used interchangeably.

[0102] WiFi belongs to short-distance wireless transmission technology. The mobile terminal can help users receive and send emails, browse the web, and access streaming media through the WiFi module 102, which provides users with wireless broadband Internet access. Although Figure 1 the WiFi module 102 is shown, it can be understood that it does not belong to an essential component of the mobile terminal and can be omitted entirely within the scope of not changing the essence of the invention as needed.

[0103] The audio output unit 103 can convert the audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in modes such as a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, and so on. Moreover, the audio output unit 103 can also provide an audio output related to a specific function executed by the mobile terminal 100 (for example, a call signal reception sound, a message reception sound, etc.).

The processed audio (voice) data can be output in a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in the case of a phone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) the noise or interference generated during the reception and transmission of the audio signal.

[0105] The mobile terminal 100 further includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a kind of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary, and can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as a pedometer, a knock), etc.; as for other sensors that the mobile phone can also be configured with, such as a fingerprint sensor, a pressure sensor, an iris sensor, a molecular sensor, a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, etc., they will not be elaborated here.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the touch operations of the user on or near it (such as the operations of the user using a finger, a stylus, or any suitable object or accessory on or near the touch panel 1071), and drive the corresponding connection device according to a preset program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the touch position of the user and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 110, and can receive the commands sent by the processor 110 and execute them. And / or, the touch panel 1071 can be implemented in multiple types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072.

[0108] Optionally, the touch panel 1071 may cover the display panel 1061. After the touch panel 1071 detects a touch operation on or near it, it transmits the operation to the processor 110 to determine the type of the touch event. Subsequently, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Although in Figure 1 the touch panel 1071 and the display panel 1061 are implemented as two independent components to realize the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to realize the input and output functions of the mobile terminal, and specific details are not limited here.

The interface unit 108 can be used to receive inputs from the external device (such as data information, power, etc.) and transmit the received inputs to one or more components within the mobile terminal 100, or can be used to transfer data between the mobile terminal 100 and the external device.

[0110] The memory 109 can be used to store software programs and various data. The memory 109 mainly includes a program storage area and a data storage area. Optionally, the program storage area can store an operating system, applications required for at least one function (such as a sound playback function, an image playback function, etc.); the data storage area can store data created according to the use of the mobile phone (such as audio data, phone book, etc.). And / or, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one magnetic disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0111] The processor 110 is the control center of the mobile terminal, connecting various parts of the entire mobile terminal using various interfaces and lines. By running or executing the software programs and / or modules stored in the memory 109, and calling the data stored in the memory 109, it performs various functions of the mobile terminal and processes data, thereby monitoring the mobile terminal as a whole. The processor 110 can include one or more processing units; preferably, the processor 110 can integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and applications, etc., and the modem processor mainly processes wireless communication. It can be understood that the above-mentioned modem processor may not be integrated into the processor 110.

[0112] The mobile terminal 100 can also include a power supply 111 (such as a battery) for powering each component. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby implementing functions such as management of charging, discharging, and power consumption management through the power management system.
