According to the current technology, the GPS module 115 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS module 115 can calculate speed information by continuously calculating current position information in real time.
The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal 100.

The user input unit 130 may generate key input data to control various operations of the mobile terminal 100 according to a command input by a user. The user input unit 130 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, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.
The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device. In practical applications, the sensing unit 140 may be implemented by a proximity sensor 141.

For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port (a typical example is a Universal Serial Bus (USB) port), a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means.
The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and the external device.
In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal 100. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal 100 is accurately mounted on the cradle.
The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.
Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 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. Depending on the particular desired implementation, mobile terminal 100 may include two or more display units (or other display devices), for example, mobile terminal 100 may include an external display unit (not shown) and an internal display unit (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 audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.
The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like.

For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (communicating communication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.
The memory 160 may store software programs or the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, etc.) that has been output or is to be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.
A communication system in which the mobile terminal 100 according to the present invention is capable of operating will now be described with reference to fig. 2.
Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.
Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC 280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC 280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 2750.
Each BS 270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS 270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz, 5MHz, etc.).
The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cell sites.
As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several satellites 300 are shown, for example, Global Positioning System (GPS) satellites 300 may be employed. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.
In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal 100 may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.
As a typical operation of the wireless communication system, the BS 270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC 280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS 270 to transmit forward link signals to the mobile terminal 100.
The mobile communication module 112 of the wireless communication unit 110 in the mobile terminal accesses the mobile communication network based on the necessary data (including the user identification information and the authentication information) of the mobile communication network (such as the mobile communication network of 2G/3G/4G, etc.) built in the mobile terminal, so as to transmit the mobile communication data (including the uplink mobile communication data and the downlink mobile communication data) for the services of web browsing, network multimedia playing, etc. of the mobile terminal user.
The wireless internet module 113 of the wireless communication unit 110 implements a function of a wireless hotspot by operating a related protocol function of the wireless hotspot, the wireless hotspot supports access by a plurality of mobile terminals (any mobile terminal other than the mobile terminal), transmits mobile communication data (including uplink mobile communication data and downlink mobile communication data) for mobile terminal user's services such as web browsing, network multimedia playing, etc. by multiplexing the mobile communication connection between the mobile communication module 112 and the mobile communication network, since the mobile terminal essentially multiplexes the mobile communication connection between the mobile terminal and the communication network for transmitting mobile communication data, the traffic of mobile communication data consumed by the mobile terminal is charged to the communication tariff of the mobile terminal by a charging entity on the side of the communication network, thereby consuming the data traffic of the mobile communication data included in the communication tariff contracted for use by the mobile terminal.

Here, the connection may particularly be a connection by a shorting pin, such as the metal piece connected with the at least one adjustable part by a shorting pin.
Specifically, the embodiments of the present invention are further described in detail with reference to fig. 5 and 6; as shown in fig. 5 and 6, the covering member is a semi-surrounding covering member, that is, the covering member is used for covering the edge area and the back area of the electronic device, and does not cover the display area of the electronic device, so that a user can browse the display area through the uncovered area; further, the metal part is disposed on a back region of the covering part, where a position on the covering part where the metal part is disposed is referred to as a target position, and the target position corresponds to at least one adjustable portion of an antenna body in the electronic device, so as to directly connect or couple the at least one adjustable portion. Further, when the antenna body is specifically disposed in the bottom region of the electronic device, the metal member is specifically disposed in the covering member at a target position corresponding to the bottom of the back region of the electronic device, and extends from one side to the other side of the back region in the electronic device, so as to increase an effective length of the antenna body disposed in the electronic device. Here, in practical applications, in order to increase the effective length of the antenna body to the maximum, the metal piece is connected or coupled to an end of the antenna body, that is, connected or coupled to an end of the working antenna corresponding to the lowest frequency band supported by the antenna body.
In a specific embodiment, the housing of the electronic device is a non-metal housing.
In another specific embodiment, the antenna body specifically includes N adjustable portions connected in series, for example, as shown in fig. 4, the N adjustable portions are respectively: antenna part 1, antenna part 2, antenna part i to antenna part N; n is a positive integer greater than or equal to 2; i is a positive integer which is more than or equal to 2 and less than or equal to N; the adjustable parts are connected through a second switch circuit, and the connection and disconnection of the adjustable parts are controlled by controlling the on-off of the second switch circuit, so that the effective length of the antenna body is adjusted.
Further, in another specific embodiment, the main body portion is connected to a first adjustable portion of the N adjustable portions through the first switch circuit, and the first adjustable portion is sequentially connected to a second adjustable portion, an ith adjustable portion, and an nth adjustable portion through a second switch circuit; for example, as shown in fig. 4, the antenna part 0 is connected to the antenna part 1 through a first switch circuit, the antenna part 1 is connected to the antenna part 2 through a second switch circuit, the antenna part 2 is connected to the antenna part 3 through a second switch circuit, and so on, and two adjacent adjustable parts are connected through a second switch circuit, so as to adjust the effective length of the antenna body. Correspondingly, the metal piece is connected with the Nth adjustable part, for example, the metal piece is connected with the antenna part N or is in near-field coupling with the antenna body, so that the effective length of the antenna body is increased by increasing the effective length of the current of the low-frequency branch, and a foundation is laid for increasing the working frequency band of the electronic equipment.
In practical application, as shown in fig. 4, the antenna body further includes a control circuit, and the control circuit is connected to the first switch circuit and all the second switch circuits, and is configured to control on/off of the first switch circuit and the second switch circuits, so as to adjust the effective length of the antenna body.
Fig. 4 is a detailed description of a specific working process of the antenna body according to the embodiment of the present invention; specifically, the antenna body may specifically include the following operating states:
in the state 1, that is, when the first switch circuit and all the second switch circuits are turned off, the antenna body only includes the antenna portion 0, and at this time, the antenna body can operate in the frequency band portion with the highest frequency, such as the high frequency band of 2300 and 2500 MHz.
Along with the increase of the effective length of the antenna body, the working frequency band of the antenna body is reduced. In particular, the amount of the solvent to be used,
and in a state 2, namely when the first switch circuit is closed and the second switch circuits are both opened, the antenna body comprises an antenna part 0 and an antenna part 1, and at the moment, the antenna body can work in a first-stage frequency band which is lower than a high-frequency band corresponding to the state 1.
And a state 3, namely when the first switch circuit and the first second switch circuit are closed, here, the closing of the first second switch circuit means that the second switch circuit between the antenna part 1 and the antenna part 2 is closed, and the antenna body comprises the antenna part 0, the antenna part 1 and the antenna part 2, at this time, the antenna can work in a second-stage frequency band which is lower than the first-stage frequency band corresponding to the state 2.
In this way, in the state N, that is, when the first switch circuit and the second switch circuit are both closed, the antenna body includes the antenna portion 0, the antenna portion 1, the antenna portion 2, and the antenna portion i to the antenna portion N, and at this time, the antenna body can operate in the frequency band portion with the lowest frequency, such as the low frequency band of 800 and 900 MHz.
Here, since the operating frequency, that is, the resonant frequency of the antenna is mainly determined by the electrical length (also referred to as the effective length in this embodiment) of the antenna, in this embodiment of the present invention, the antenna body is divided into several parts, and the used parts are connected by the switch circuit, so as to flexibly adjust the electrical length of the antenna body, for example, the effective length of the antenna body is controlled to be about one quarter of the required wavelength, so as to adjust the resonant frequency of the antenna body. Further, in practical application, as shown in fig. 4, an adjustable matching circuit may be further disposed in the antenna body, so as to further optimize the impedance of the antenna body in each switching mode, so as to optimize the performance of the antenna body. Here, the switching circuit can select an antenna switching circuit with power tolerance and non-linear characteristics meeting requirements, so as to ensure that the antenna body can work under high power and additional stray radiation is not generated.
Furthermore, in the antenna structure according to the embodiment of the present invention, the antenna body is a reconfigurable structure, that is, the effective length of the antenna body can be freely switched among a plurality of states by adjusting the switching states between the antenna portions (such as the main body portion and the adjustable portion), so that the antenna body can only support a required frequency band at the same time, the requirement of the multi-frequency antenna on the antenna space is reduced, and the miniaturization and the intellectualization of the antenna are realized.
In this way, in the antenna structure according to the embodiment of the present invention, the antenna body provided in the electronic device is connected or coupled to the metal piece in the covering member for covering at least the edge region of the electronic device, so that the purpose of increasing the effective length of the antenna body by using another metal piece other than the electronic device is achieved, and the operating frequency band of the electronic device is extended by increasing the effective length of the antenna body; meanwhile, the antenna body in the embodiment of the invention is an antenna with the effective length capable of being freely adjusted, so that the antenna structure in the embodiment of the invention expands the working frequency band of the electronic equipment, simultaneously realizes the purpose that the antenna body only supports the required frequency band at the same time, reduces the requirement of the multi-frequency antenna on the antenna space, and realizes the miniaturization and intellectualization of the antenna.
Example two
Based on the method described in the first embodiment, in this embodiment, the effective length of the antenna body may be set according to a frequency band that needs to be supported by the electronic device; specifically, the effective length of the body portion is a first length; the first length and the wavelength corresponding to the first frequency range meet a preset rule, so that the electronic equipment can utilize the main body part to enable the working frequency range of the electronic equipment to be within the first frequency range; for example, the first length is a quarter of a wavelength corresponding to an operating frequency (e.g., 2300-2500MHz high frequency band) when the antenna body is in the state 1 described in the first embodiment. Here, the first frequency band range may specifically correspond to the high frequency band of 2300 minus 2500 MHz. That is, the first length of the main body determines a frequency band range of the highest frequency that the antenna body can support.
After the main body part is sequentially connected with all the adjustable parts, the effective length of the antenna body is a second length; the second length is greater than the first length; and the second length and the wavelength corresponding to the second frequency range meet a preset rule, so that the electronic equipment can utilize the main body part and all the adjustable parts to enable the working frequency range of the electronic equipment to be in the second frequency range. In a specific embodiment, the second length may be specifically a longest effective length corresponding to the main body portion connected to all the adjustable portions in sequence, for example, the second length is a quarter of a wavelength corresponding to an operating frequency (e.g., a low frequency band of 800 MHz and 900 MHz) when the antenna body is in the state N described in the first embodiment. Here, the second frequency band range may specifically correspond to the 800-900MHz low frequency band. That is, the second length determines a frequency band range of the lowest frequency that the antenna body can support. Thus, when the effective length of the antenna body is changed between the first length and the second length, the frequency band supported by the antenna body is changed from the first frequency band range to the second frequency band range.
In practical applications, the effective length of the antenna body corresponding to the state N in the first embodiment is the longest effective length, and when the antenna body is in the longest effective length, the antenna body cannot support a lower frequency band, such as 700MHz, and at this time, the effective length of the antenna body can be increased by using the metal piece in the first embodiment of the present invention; specifically, after the metal piece is connected to the at least one adjustable portion or is in near-field coupling with the antenna body, for example, when the antenna body is in the state N described in the first embodiment, the metal piece may be connected to the antenna portion N or in near-field coupling with the antenna body, and at this time, the effective length of the antenna body is a third length; the third length is greater than the second length; thereby increasing the effective length of the antenna body; here, a preset rule (for example, the third length is one quarter of a wavelength corresponding to 700MHz) is satisfied between the third length and a wavelength corresponding to a preset target frequency range (for example, 700MHz), so that the electronic device can utilize the antenna structure to enable its own operating frequency band to be within the target frequency range.
Therefore, the purpose of increasing the effective length of the antenna body can be achieved without directly increasing the effective length of the antenna body in the electronic equipment, and therefore the method provided by the embodiment of the invention is simple and has strong operability.

Therefore, the effective length of the antenna body arranged in the electronic equipment is increased through the metal piece in the cladding piece, so that the effective length of the antenna body in the electronic equipment is increased under the condition that the antenna wiring structure of the existing electronic equipment is not changed, and the frequency range supported by the antenna body is expanded.
