Electronic equipment

Technical Field

The application relates to the technical field of terminals, in particular to an electronic device.

Background

The FM (frequency modulation) function of a conventional electronic device (e.g., a mobile phone, a tablet computer, etc.) is generally implemented by using a pull-rod antenna, or using an earphone cable as an FM broadcast antenna, or using an independent built-in FM broadcast antenna (e.g., an antenna device made of a dedicated flexible line antenna or a magnetic core copper wire).

The scheme of the pull rod type FM antenna can affect the attractiveness and the use convenience of the mobile phone, and the pull rod type FM antenna is poor in reliability and high in cost, so that the structure is gradually eliminated; the scheme that the earphone wire is used as the FM antenna needs to insert earphones when listening to the broadcast, so that the normal use and convenience of the mobile phone are influenced, and when the earphone wire is used as the FM antenna, a plurality of people cannot be allowed to listen to the FM broadcast on one electronic device at the same time, so that the earphone wire is used as the built-in FM antenna to limit the application of the FM broadcast; the solution of using a separate built-in FM antenna requires an expensive built-in antenna device due to the size and headroom limitations of the electronic device, and the number of channels searched and the broadcasting performance are poor.

Moreover, along with the development of science and technology, the structural design of the electronic equipment becomes more and more refined and complicated, the antenna clearance area required when the frequency modulation broadcasting function is set on the electronic equipment is limited, and the fully-built-in FM antenna is trapped in the bottleneck.

The electronic equipment comprises an equipment body, wherein the equipment body is provided with a rear camera assembly, and a frequency modulation broadcasting circuit and a conductive connecting body are arranged in the equipment body; the rear camera component comprises a camera and a camera structural component, wherein a mounting hole matched with the camera is formed in the camera structural component and used for fixing the camera, and when the camera and the camera component are mounted, the camera penetrates through the mounting hole in the camera structural component and protrudes out of the equipment body; a metal ring is arranged on the camera structure part in a manner of surrounding the camera, and the metal ring is used for forming an FM antenna; the frequency modulation broadcasting circuit comprises a processing module, an amplifier and a filtering module, wherein the amplifier is respectively coupled with the processing module and the filtering module, and the filtering module is grounded; the metal ring is coupled with the frequency modulation broadcasting circuit through the conductive connector, and the metal ring is used as an FM antenna to facilitate the receiving of broadcasting signals so as to realize the good channel searching quantity and broadcasting performance of the frequency modulation broadcasting circuit; the broadcast signals received by the metal ring are transmitted to the amplifier through the signal transmission medium, and the weak broadcast signals are amplified by the amplifier and then sent to the processing module for processing, so that the processing of the broadcast signals and the sound playing are realized. The filtering module is used for eliminating noise signals outside the frequency band of the received broadcast signals, so that the amplifier receives more accurate broadcast signals. Of course, depending on the type of the electronic device, the rear camera assembly may be replaced by a fingerprint interaction assembly, an earpiece dust screen assembly, a battery cover assembly, or a combination of at least two of the above structures. It can be seen that the FM antenna which adopts the metal structure on the structural component of the electronic equipment (for example, the metal ring on the camera structural component of the rear camera component) as the built-in FM broadcast makes full use of the clearance environment of the electronic equipment, does not additionally increase the structure, can ensure the use convenience and the aesthetic property of the electronic equipment while reducing the cost, and brings more comfortable use experience for consumers.

The structure of the metal ring can be a metal part embedded in the camera body, can also be a metal coating formed on the camera body, and can also be a metal structure in other forms, so that the FM function can be realized.

The conductive connector can be made of at least one of metal, conductive adhesive or conductive foam, and the conductive connector made of the materials can achieve a good conductive effect, so that broadcast signals received by a metal ring of the rear camera assembly can be conveniently transmitted to the frequency modulation broadcast circuit. According to the type of the selected structural component (such as any one or the combination of two of a rear camera component, a fingerprint interaction component, a receiver dustproof net component and a battery cover component) and the difference of the setting position, when the material of the conductive connecting body is selected from metal, the specific realization structure of the conductive connecting body can be at least one of a spring sheet, a screw or a lead in order to adapt to the specific use environment; the metal can be one or more of copper, iron, aluminum, steel, aluminum alloy and nickel-copper alloy.

In a possible implementation manner, the filtering module includes a filtering capacitor and a filtering inductor which are arranged in parallel. The filter capacitor and the filter inductor which are arranged in parallel form an LC type passive filter, which not only can play a role in filtering, but also can meet the requirement of reactive compensation. In addition, in order to eliminate the problem that the rear camera assembly may generate static electricity, the fm broadcast circuit further includes an electrostatic discharge processing module, one end of the electrostatic discharge processing module is coupled to the amplifier and the conductive connecting body, and the other end of the electrostatic discharge processing module is grounded.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

First, an application scenario of the present application is introduced: the FM function is a very common application function in daily life, and an FM antenna of the conventional electronic device is poor in reliability and high in cost, or affects convenience and attractiveness of normal use of a mobile phone; and along with scientific and technological development, electronic equipment's structural design is more and more refined and complicated, and required antenna clearance area has received great restriction when setting up FM on electronic equipment for realize the design of full built-in FM antenna and fall into the bottleneck in electronic equipment.

Based on the application scenario, the embodiment of the application provides an electronic device, which can be a mobile phone or a tablet computer, and the metal structure of the structural component of the electronic device is used as the FM antenna of the built-in broadcast circuit of the electronic device, so that the requirements of the electronic device on portability and aesthetic property are met while good broadcast performance is ensured. As shown in fig. 1 and fig. 2, taking the electronic device as an example of a mobile phone, the structural components of the mobile phone itself may be a rear camera component 11a, a fingerprint interaction component 11b, a battery cover component 11c as shown in fig. 1, or a headphone dust screen component 11d as shown in fig. 2, and as long as the structural components have a metal material portion, the metal material portion may be used as an FM antenna of the mobile phone built-in broadcasting circuit of this embodiment.

The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of this application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

As shown in fig. 3 to fig. 5, the structure component 11 of the device body 1 of the electronic device provided in this embodiment has a metal material portion, and the specific implementation structure of the structure component 11 may be any one of or a combination of at least two of the rear camera component 11a, the fingerprint interaction component 11b, the battery cover component 11c, and the earpiece dust screen component 11d shown in fig. 1 and fig. 2. In the apparatus body 1, these structural components 11 described above each have a good clearance environment. In some embodiments, the metal material portion of the structural component 11 may be used as an FM antenna for receiving or radiating broadcast signals during communication of the electronic device. Illustratively, the structural component 11 shown in fig. 3 is made of metal as a whole, or a portion (shown as a shaded portion M in fig. 4) of the structural component 11 shown in fig. 4 is made of metal. As shown in fig. 5, the casing 1a of the device main body 1 is generally made of an insulating material, and even if the metal material portion (e.g., the hatched portion N in fig. 5) of the component 11 is not exposed to the device main body 1, the insulating material casing 1a does not affect the antenna performance of the metal material portion of the component 11, and the metal material portion of the component 11 can still exhibit a good signal receiving or radiating effect. It should be understood that the metal material portion of the structural component 11 has no direct coupling relationship with other metal structures of the device body 1 other than the coupling relationship with the built-in FM broadcast, and only serves as an FM antenna for coupling with the built-in FM broadcast.

As shown in fig. 3 to 5, a conductive connector 4 is disposed in the device body 1 for coupling the metal material portion of the structural component 11 and the FM broadcast circuit 2, so as to realize signal transmission between the metal material portion of the structural component 11 serving as the FM antenna and the FM broadcast circuit 2. As shown in fig. 3 to 5, the fm broadcast circuit 2 may specifically include a filtering module 24, an amplifier 22, a processing module 23, an electrostatic discharge processing module 25, and a connecting elastic sheet 21 for connecting the conductive connector 4, which are disposed on the main board 3. Thus, the broadcast signal received by the metal material part of the structural component 11 is transmitted to the connecting elastic sheet 21 through the conductive connector 4, enters the fm broadcast circuit 2 through the connecting elastic sheet 21, and then reaches the processing module 23 for signal processing after being processed by the electrostatic discharge processing module 25, the filtering module 24 and the amplifier 22 in sequence.

Aiming at the original structure of the structural assembly 11 on the device body 1, the structural assembly 11 may have an Electrostatic Discharge (EDS) problem, and the electrostatic discharge phenomenon occurring in the structural assembly 11 can be prevented by the connection between the electrostatic discharge processing module 25 and the connecting elastic sheet 21. The filtering module 24 may be configured to eliminate a noise signal outside a broadcast signal frequency band in the received signal, and the amplifier 22 may amplify the received weak broadcast signal, which is beneficial for the processing module 23 to obtain a broadcast signal with high quality.

In an exemplary implementation of the structural component 11, a portion of which is made of a metal material, as shown in fig. 6 to 8, the structural component 11 may include a structural body 111 made of a non-metal material and a metal structural body 112 disposed on the structural body 111. The metal structure 112 may be mounted on the structure body 111 by means of embedding, adhering, coating, or the like. According to different configurations, the metal structure 112 may be a metal component embedded in the structure body 111 (as shown in fig. 6, a cross-sectional structure of the metal structure 112 embedded in the structure body 111, or as shown in fig. 7, a cross-sectional structure of the metal structure 112 embedded in the structure body 111 and exposed out of the surface of the structure body 111), or the metal structure 112 may be a metal plating film formed on the structure body 111 (as shown in fig. 8, a cross-sectional structure).

For example, the conductive connector 4 may be made of at least one of metal, conductive adhesive or conductive foam having good conductivity, and the conductive connector 4 made of these materials can achieve a good electrical connection effect, so that the broadcast signal received by the metal material of the structural component 11 can be transmitted to the fm broadcast circuit 2 built in the electronic device in time. Specifically, when the metal material is selected, one or a combination of more of copper, iron, aluminum, steel, an aluminum alloy, and a nickel-copper alloy may be selected. It should be noted that, if the conductive connecting body 4 is made of at least two metal materials, the at least two metal materials may be combined together by a process such as splicing, welding, rolling, and the like. Meanwhile, when the conductive connecting body 4 is made of metal, different structural implementation manners can be selected by considering the internal structure of the electronic device and the position of the frequency modulation broadcasting circuit 2 on the main board 3, for example, the conductive connecting body 4 may be a metal elastic sheet with a sheet structure, a metal wire with a wire body structure, a metal screw with a rod-shaped structure, or the like.

The above description merely exemplifies various implementations of the structural component 11, and specifically adopts which implementation or adopts other structures besides the above implementations as the structural component 11, and the embodiment is not limited here.

Of course, the metal ring a1 can also be formed on the camera body a by metal plating.

The conductive connector 4 may be a metal screw, and the tail of the metal screw passes through the metal extension structure B in the earpiece dust screen assembly 11d, extends toward the main board 3 (not shown in fig. 12) of the mobile phone, and is connected to the connection spring 21 of the fm broadcast circuit 2. It should be understood that other structural descriptions and broadcast signal receiving processing procedures in this example can refer to the detailed description of example 1 above, and are not repeated here.

Example 5: as shown in fig. 13, the structural component 11 may be a handset dust screen component 11D of a mobile phone, and unlike example 3, the handset dust screen component 11D has an insulating material structure D and a metal extension structure D1 (shown as a shaded area at one end of the length direction of the handset dust screen component 11D in fig. 13) disposed at one end of the insulating material structure D in an embedded manner, where the metal extension structure D1 may form an FM antenna. The conductive connector 4 may be a metal screw, and the tail of the metal screw passes through the metal extension structure D1 in the earpiece dust screen assembly 11D, extends toward the main board 3 (not shown in fig. 13) of the mobile phone, and is connected to the connection spring 21 of the fm broadcast circuit 2. It should be understood that other structural descriptions and broadcast signal receiving processing procedures in this example can refer to the detailed description of example 1 above, and are not repeated here.

The two connecting

elastic pieces

21a and 21d are connected and converged at point P by routing and then enter the tuner broadcasting circuit 2. In this example, the camera structure 11a-2 and the earpiece dust screen assembly 11d collectively function as an FM antenna to receive broadcast signals. It should be noted that, in this example, the connection meeting point P of the two connection

elastic pieces

21a and 21d is located before the other module structures of the FM broadcast circuit 2, that is, before the broadcast signals transmitted by the two FM antennas enter the point P of the FM broadcast circuit 2, only the signal transmission is performed but the signal processing is not performed, and after the broadcast signals enter the FM broadcast circuit 2, the broadcast signals are processed by the electrostatic discharge processing module 25, the filter module 24, the amplifier 22, and the processing module 23. It should be understood that other structural descriptions and broadcast signal receiving processing procedures in this example can refer to the detailed description of example 1 above, and are not repeated here.

Example 7: as shown in fig. 15, the structural assembly 11 may be a combination of a rear camera assembly 11a, a headphone dust screen assembly 11d, and a battery cover structural member 11c (not shown in fig. 15) of the cellular phone.

The fm broadcast circuit 2 is correspondingly provided with a conductive connector 4a connected with the elastic sheet 21a to connect with the camera structural member 11a-2, a conductive connector 4D connected with the elastic sheet 21D to connect with the metal extension structure D1 of the earpiece dust screen assembly 11D, and a conductive connector 4C connected with the elastic sheet 21C to connect with the metal plating layer C of the battery cover structural member 11C.

It should be noted that, in this example, the connection meeting point P of the three connection

elastic pieces

It should be understood that other structural descriptions and broadcast signal receiving processing procedures in this example can refer to the detailed description of example 1 above, and are not repeated here.

Of course, the above examples are merely illustrative of a few possible embodiments, and additional implementations are possible. For the structure setting of the connection elastic sheet 21, it is necessary to avoid other structures inside the electronic device as much as possible and approach the main board 3 as much as possible, so that the distance between the conductive connection body 4 and the connection elastic sheet 21 is the shortest, and it is to be ensured that no FM frequency band interference source exists near the position of the connection elastic sheet 21. It is to be understood that the arrangement positions and structures of the structural components 11 in the drawings corresponding to the above examples are only schematic illustrations made for explaining the coupling relationship between the structures in the present embodiment, and do not limit the specific positions and structures of the suspended structural components 11 on the electronic device in practical applications, for example, the fingerprint interaction structural component 11b on the electronic device may also be used as the structural component 11.

For example, on the basis of the electronic device shown in fig. 3, as shown in fig. 16, an amplifier 22, a processing module 23, and a filtering module 24 may be disposed on the main board 3, and one end of the amplifier 22 is coupled to the connecting elastic sheet 21 and the processing module 23 through a connecting line; one end of the filter module 24 is coupled to the connection elastic sheet 21 and the amplifier 22, and the other end is grounded. Further, the processing module 23 may specifically include a signal processing component 231 and an audio processing component 232 connected, and the signal processing component 231 is coupled with the amplifier 22. The broadcast signal received by the connecting elastic sheet 21 is identified and converted into an electric signal by the signal processing component 231, and the information carried by the electric signal is converted by the audio processing component 232 to obtain a sound signal and played, so that the user can listen to the sound signal conveniently. It is understood that the signal processing component 231 herein may be a processor of the electronic device itself, and the audio processing component 232 herein may further include a speaker for playing sound, where the speaker may be a speaker of the electronic device itself, or an external speaker device (e.g., a headset, a sound box, etc.) plugged into the electronic device.

In addition, as shown in fig. 17, on the basis of the electronic device shown in fig. 16, the filtering module 24 may adopt an LC filter, and specifically may include a filtering capacitor and a filtering inductor which are arranged in parallel. The filter capacitor and the filter inductor which are arranged in parallel form an LC type passive filter, which not only can play a role in filtering, but also can meet the requirement of reactive compensation, and is suitable for signal processing.

It should be noted that, as shown in fig. 3 to 5 and fig. 9 to 17, the esd processing module 25 and the filter module 24 are both disposed between the connecting elastic sheet 21 and the amplifier 22, but the esd processing module 25 may be disposed at a position closer to the connecting elastic sheet 21 than the filter module 24.

As can be seen from the foregoing description, in the present application, the metal part in the structural component 11 of the electronic device itself (for example, the rear camera component of the mobile phone) is used as an FM antenna with a built-in FM broadcast circuit, so that broadcast signals are received conveniently, and good channel searching quantity and broadcast performance can be achieved; meanwhile, the antenna structure fully utilizes the clearance environment of the electronic equipment, the structure and the volume of the electronic equipment cannot be additionally increased, the use convenience and the attractiveness of the electronic equipment can be ensured while the cost is reduced, and more comfortable use experience is brought to consumers.
