Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The mobile phone in the prior art can generally realize the conventional call function and the public network talkback and DMR (digital mobile radio) talkback function. For example, conventional telephony functions typically include handset telephony, hands-free telephony, headset telephony, and bluetooth telephony. The public network talkback and DMR talkback functions comprise hands-free talkback and earphone talkback. Although the mobile phone can realize the functions, some inconvenience still exists in the application. For example, when a headset or a microphone device with an M6 interface is required to perform talk, the existing mobile phone cannot realize the function. The function of the earphone or the hand microphone device talkback through the M6 interface is realized through the following design.

Fig. 1 is a schematic diagram of a hardware structure of an optional mobile phone for implementing various embodiments of the present application.

The cellular phone 100 may include a user input unit 110, a sensing unit 120, an output unit 130, a memory 140, a processor 150, a power supply unit 160, and a radio frequency module 170, etc. Fig. 1 shows a cell phone 100 having various components, but it is understood that not all of the illustrated components are required to be implemented, and that more or fewer components may alternatively be implemented, the elements of the cell phone 100 being described in detail below.

The user input unit 110 may generate key input data to control various operations of the cellular phone 100 according to a command input by a user. The user input unit 110 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, etc. due to being touched), scroll wheel, joystick, etc. In particular, when the touch panel is superimposed on the display sub-module 131 in the form of a layer, a touch screen may be formed.

The sensing unit 120 detects a current state of the cellular phone 100 (e.g., an open or closed state of the cellular phone 100), a position of the cellular phone 100, presence or absence of contact (i.e., touch input) of the user with the cellular phone 100, an orientation of the cellular phone 100, acceleration or deceleration movement and direction of the cellular phone 100, and the like, and generates a command or signal for controlling an operation of the cellular phone 100. For example, when the cell phone 100 is implemented as a slide type mobile phone, the sensing unit 120 may sense whether the slide type phone is opened or closed. In addition, the sensing unit 120 can detect whether the power supply unit 160 supplies power. The sensing unit 120 may include a proximity sensor 121.

The output unit 130 may include a display sub-module 131 and the like.

When the handset 100 is in a video call mode or image. In the capture mode, the display sub-module 131 may display captured images and/or received images, a UI or GUI showing video or images and related functions, and the like.

The display sub module 131 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. According to certain desired embodiments, the handset 100 may include two or more display modules (or other display devices), for example, the handset 100 may include an external display module (not shown) and an internal display module (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The memory 140 may store software programs or the like for processing and controlling operations performed by the processor 150, or may temporarily store data (e.g., a phonebook, messages, still images, video, etc.) that has been or will be output. Also, the memory 140 may store data regarding various manners of vibration and audio signals output when a touch is applied to the touch screen.

The memory 140 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and so on. Also, the handset 100 may cooperate with a network storage device that performs the storage function of the memory 140 through a network connection.

The processor 150 generally controls the overall operation of the handset 100. For example, the processor 150 performs control and processing related to voice calls, data communications, video calls, public network talkback, data mobile radio talkback data analysis, and so forth. The processor 150 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images.

The power supply unit 160 receives external power or internal power and provides appropriate power required to operate the elements and components under the control of the processor 150.

The rf module 170 receives an analog signal and converts the analog signal into a digital signal through the antenna under the control of the processor 150, or converts the digital signal transmitted by the processor 150 into an analog signal and transmits the analog signal through the antenna, thereby implementing a call function of the terminal.
