For example, the electronics body section 10 may also include more or fewer components than shown in FIG. 15, or have a different configuration than shown in FIG. 15.

Those skilled in the art will appreciate that all other components are peripheral devices with respect to the processor 102, and the processor 102 is coupled to the peripheral devices through a plurality of peripheral interfaces 124. The peripheral interface 124 may be implemented based on the following criteria: universal Asynchronous Receiver/Transmitter (UART), General Purpose Input/Output (GPIO), Serial Peripheral Interface (SPI), and Inter-Integrated Circuit (I2C), but the present invention is not limited to these standards. In some examples, the peripheral interface 124 may comprise only a bus; in other examples, the peripheral interface 124 may also include other elements, such as one or more controllers, for example, a display controller for interfacing with the display panel 111 or a memory controller for interfacing with a memory. These controllers may also be separate from the peripheral interface 124 and integrated within the processor 102 or a corresponding peripheral.

The memory 104 may be used to store software programs and modules, and the processor 102 executes various functional applications and data processing by executing the software programs and modules stored in the memory 104. The memory 104 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include memory located remotely from the processor 102, which may be connected to the electronic body portion 10 or the primary display 120 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The RF module 106 may include various existing circuit elements for performing these functions, such as an antenna, a radio frequency transceiver, a digital signal processor, an encryption/decryption chip, a Subscriber Identity Module (SIM) card, memory, and so forth. The RF module 106 may communicate with various networks such as the internet, an intranet, a wireless network, or with other devices via a wireless network. The wireless network may comprise a cellular telephone network, a wireless local area network, or a metropolitan area network. The Wireless network may use various Communication standards, protocols and technologies, including, but not limited to, Global System for Mobile Communication (GSM), Enhanced Mobile Communication (Enhanced Data GSM Environment, EDGE), wideband Code division multiple Access (W-CDMA), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Wireless Fidelity (WiFi) (e.g., IEEE 802.10A, IEEE802.11b, IEEE802.11g and/or IEEE802.11 n), Voice over internet protocol (VoIP), world wide mail Access (Microwave for Wireless communications, Max), and other short message Communication protocols, as well as any other suitable communication protocols, and may even include those that have not yet been developed.

The audio circuitry 110, earpiece 101, sound jack 103, microphone 105 collectively provide an audio interface between a user and the electronic body portion 10 or the main display 120. Specifically, the audio circuit 110 receives sound data from the processor 102, converts the sound data into an electrical signal, and transmits the electrical signal to the earpiece 101. The earpiece 101 converts the electrical signal into sound waves that can be heard by the human ear. The audio circuitry 110 also receives electrical signals from the microphone 105, converts the electrical signals to sound data, and transmits the sound data to the processor 102 for further processing. Audio data may be retrieved from the memory 104 or through the RF module 106. In addition, audio data may also be stored in the memory 104 or transmitted through the RF module 106.

That is, the pressure sensor 114G detects pressure generated by contact or pressing between the user and the mobile terminal, for example, contact or pressing between the user's ear and the mobile terminal. Accordingly, the pressure sensor 114G may be used to determine whether contact or pressing has occurred between the user and the mobile terminal 100, as well as the magnitude of the pressure.

Referring to fig. 15 again, in the embodiment shown in fig. 15, the light sensor 114F and the pressure sensor 114G are disposed adjacent to the display panel 111.

Optionally, the touch screen 109 may include 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 102, and can receive and execute commands sent by the processor 102. In addition, the touch detection function of the touch screen 109 may be implemented by various types, such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch screen 109, in other variations, the input module 118 may include other input devices, such as keys 107. The keys 107 may include, for example, character keys for inputting characters, and control keys for activating control functions. Examples of such control keys include a "back to home" key, a power on/off key, and the like.

The main display 120 is used to display information input by a user, information provided to the user, and various graphic user interfaces of the electronic body section 10, which may be composed of graphics, text, icons, numbers, video, and any combination thereof, and in one example, the touch screen 109 may be provided on the display panel 111 so as to be integrated with the display panel 111.
