Description

Technical Field

[0001] The present application relates to the technical field of camera devices, and in particular to a camera module and electronic equipment. Background Art

[0002] With the rapid development of electronic devices such as smart phones, tablet computers, and e-readers, the camera modules in electronic devices also tend to be diversified in design to meet different shooting needs. Some electronic devices are equipped with periscope camera modules to obtain higher optical magnification shooting effects, and are equipped with voice coil motor components to achieve optical zoom focus function. However, in the related art, the camera module with optical zoom function occupies a large space, which is not conducive to the structural layout of the electronic device. Summary of the invention

[0003] The embodiments of the present application provide a camera module and an electronic device to solve the problem that a camera module with an optical zoom function occupies a large space.

[0004] A camera module, comprising:

[0005] A first conductive element having a first light incident surface, a first reflective surface and a first light emitting surface, wherein the first conductive element is capable of reflecting at least part of the light incident from the first light incident surface and emitting from the first light emitting surface after being reflected by the first reflective surface;

[0006] a second conductive element, having a second light incident surface, a second reflective surface, and a second light emitting surface, wherein the second conductive element is capable of emitting at least part of the light incident from the second light incident surface through the second light emitting surface after being reflected by the second reflective surface, the second light incident surface is opposite to the first light emitting surface, and the second light emitting surface and the first light incident surface face the same side; and

[0007] A zoom lens group is arranged between the first light emitting surface and the second light incident surface. At least a part of the zoom lens group can move along the optical axis between the first conductive element and the second conductive element to realize an optical zoom function.

[0008] In the above-mentioned camera module, the second light-emitting surface and the first light-entering surface face the same side, and the first conductive element and the second conductive element cooperate to be able to deflect the optical path by 180°, so that when the image sensor is opposite to the second light-emitting surface to receive the light emitted by the second conductive element, the extension direction of the image sensor is roughly perpendicular to the light-entering direction of the camera module. Thus, when it is necessary to increase the size of the image sensor or increase the aperture of the camera module to improve the imaging quality of the camera module, it is only necessary to increase the size of the image sensor, the first light-entering surface and / or the second light-emitting surface, which will not cause the size of the camera module in the light-entering direction to increase, which is conducive to compressing the size of the electronic device corresponding to the camera module in the thickness direction, thereby facilitating the structural layout of the camera module in the electronic device. In addition, by moving the zoom lens group arranged between the first conductive element and the second conductive element to realize the optical zoom function, the moving stroke of the zoom lens group is in the direction from the first light-emitting surface to the second light-entering surface, which will not cause the size of the camera module in the light-entering direction to increase, which is conducive to compressing the size of the electronic device corresponding to the camera module in the thickness direction, thereby also facilitating the structural layout of the camera module in the electronic device.

[0009] An electronic device comprises a housing and a camera module as described above, wherein the camera module is arranged in the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0019] As used herein, "electronic device" refers to a device that can receive and / or send communication signals, including but not limited to a device that is connected via any one or more of the following connection methods:

[0020] (1) Connection via wired lines, such as Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, and direct cable connection;

[0021] (2) Via wireless interfaces, such as cellular networks, wireless local area networks (WLAN), digital television networks such as DVB-H networks, satellite networks, and AM-FM broadcast transmitters.

[0022] An electronic device configured to communicate via a wireless interface may be referred to as a "mobile terminal". Examples of mobile terminals include, but are not limited to, the following electronic devices:

[0023] (1) Satellite phone or cellular phone;

[0024] (2) Personal Communications System (PCS) terminals that can combine cellular radio telephones with data processing, fax, and data communications capabilities;

[0025] (3) Radiotelephone, pager, Internet / intranet access, Web browser, notepad, calendar, Personal Digital Assistant (PDA) equipped with a Global Positioning System (GPS) receiver;

[0026] (4) conventional laptop and / or palmtop receivers;

[0027] (5) Conventional laptop and / or palmtop radio telephone transceivers, etc.

[0028] In the related art, for electronic devices equipped with periscope camera modules, the extension direction of the image sensor usually corresponds to the thickness direction of the electronic device. When it is necessary to increase the size of the image sensor to improve the resolution of the shooting module, or to increase the size of components such as prisms to increase the aperture of the shooting module, thereby improving the imaging quality of the shooting module, it usually causes the size of the camera module corresponding to the thickness direction of the electronic device to increase. In addition, in the related art, when it is necessary to set a movable lens group to achieve zoom and focus functions, the moving direction of the lens group usually also corresponds to the thickness direction of the electronic device. In order to reserve sufficient moving space, the size of the camera module in the thickness direction of the electronic device will also increase, which is not conducive to the structural layout of the electronic device.

[0029] In order to solve the above problems, the present application provides a camera module and an electronic device.

[0030] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of the electronic device 10 in some embodiments, Figure 2 Schematic diagram of the structure of the camera module 12 in some embodiments. The electronic device 10 provided in the present application includes but is not limited to any applicable electronic device such as a smart phone, a tablet computer, an e-reader, etc. The electronic device 10 is provided with a camera module 12 to realize a shooting function, and the electronic device 10 includes a housing 11 for accommodating the camera module 12, and the housing 11 is provided with a light inlet 111, and the camera module 12 can receive at least part of the light incident into the light inlet 111 to obtain an image of the subject.

[0031] In some embodiments, the camera module 12 includes a first conduction element 121, a second conduction element 122 and a zoom lens group 123. The first conduction element 121 has a first light incident surface 1211, a first reflection surface 1212 and a first light emitting surface 1213. The light from the light input hole 111 can be incident on the first conduction element 121 from the first light incident surface 1211. The first conduction element 121 can reflect at least part of the light incident from the first light incident surface 1211 through the first reflection surface 1212 and then be emitted from the first light emitting surface 1213, thereby achieving an effect of deflecting the light path. The second conductive element 122 has a second light incident surface 1221, a second reflective surface 1222, and a second light emitting surface 1223. The second light incident surface 1221 is opposite to the first light emitting surface 1213. At least part of the light of the first conductive element 121 emitted from the first light emitting surface 1213 enters the second conductive element 122 from the second light incident surface 1221. The second conductive element 122 can reflect at least part of the light incident from the second light incident surface 1221 through the second reflective surface 1222 and then emit it from the second light emitting surface 1223, thereby achieving the effect of deflecting the light path. The second light emitting surface 1223 faces the same side as the first light incident surface 1211. In other words, the first conductive element 121 cooperates with the second conductive element 122 to deflect at least part of the light incident from the light inlet 111 into the camera module 12 by 180 degrees. The zoom lens group 123 includes at least one lens 126 with optical power. The zoom lens group 123 is disposed between the first light emitting surface 1213 of the first conductive element 121 and the second light incident surface 1221 of the second conductive element 122. The zoom lens group 123 can adjust at least part of the light emitted from the first light emitting surface 1213 to the second light incident surface 1221 to improve the imaging quality of the camera module 12. In some embodiments, at least part of the zoom lens group 123 can move along the optical axis between the first conductive element 121 and the second conductive element 122 to change the focal length of the camera module 12 and realize the optical zoom function.

[0032] In some embodiments, the camera module 12 may further include an imaging lens group 125 and an image sensor 124. The imaging lens group 125 is disposed on the side of the first light incident surface 1211 of the first conductive element 121. The light incident side of the imaging lens group 125 is disposed corresponding to the light inlet hole 111, and the light exit side is opposite to the first light incident surface 1211. The imaging lens group 125 includes at least one lens 126 with optical power. The imaging lens group 125 can collect light incident from the light inlet hole 111 into the camera module 12, adjust the light, and then emit it to the first light incident surface 1211, so as to improve the imaging quality of the camera module 12. The image sensor 124 is disposed on the side of the second light exit surface 1223 of the second conductive element 122. The photosensitive surface of the image sensor 124 is opposite to the second light exit surface 1223. At least part of the light deflected by the second conductive element 122 is emitted from the second light exit surface 1223 and emitted to the image sensor 124. The image sensor 124 includes but is not limited to a charge coupled device (CCD) or a complementary metal-oxide semiconductor device (CMOS Sensor).

[0033] It can be understood that the electronic device 10 can be roughly in the shape of a rectangular parallelepiped, the axis of the imaging lens group 125 can be parallel to the thickness direction of the electronic device 10, the axis direction of the imaging lens group 125 can be regarded as the light incident direction of the camera module 12, the light incident direction of the camera module 12 corresponds to the thickness direction of the electronic device 10, the first light incident surface 1211 and the second light emitting surface 1223 can be roughly perpendicular to the thickness direction of the electronic device 10, and the movement direction of the zoom lens group 123 relative to the first conductive element 121 and the second conductive element 122 can be roughly perpendicular to the thickness direction of the electronic device 10 ( Figure 2 The photosensitive surface of the image sensor 124 is also roughly perpendicular to the thickness direction of the electronic device 10 (in the direction indicated by the double-arrow dotted line in FIG).

[0034] In the above-mentioned camera module 12, the second light emitting surface 1223 and the first light incident surface 1211 are facing the same side, and the first conductive element 121 and the second conductive element 122 cooperate to deflect the light path by 180°, so that when the image sensor 124 is opposite to the second light emitting surface 1223 to receive the light emitted by the second conductive element 122, the extension direction of the image sensor 124 is roughly perpendicular to the light incident direction of the camera module 12, and the image sensor 124, the first light incident surface 1211 and the second light emitting surface 1223 are all roughly perpendicular to the thickness direction of the electronic device 10. Therefore, when it is necessary to increase the size of the image sensor 124 or increase the aperture of the camera module 12 to improve the imaging quality of the camera module 12, the size of the image sensor 124, the first light incident surface 1211 and / or the second light exit surface 1223 can be increased, that is, the size of the camera module 12 in a direction perpendicular to the thickness of the electronic device 10 is increased. This will not cause the size of the camera module 12 in the thickness of the electronic device 10 to increase, which is beneficial to compressing the size of the camera module 12 in the thickness direction of the electronic device 10, thereby facilitating the structural layout of the camera module 12 in the electronic device 10.

[0035] In addition, by moving the zoom lens group 123 disposed between the first conductive element 121 and the second conductive element 122 to realize the optical zoom function, the movement stroke of the zoom lens group 123 is in the direction from the first light emitting surface 1213 to the second light incident surface 1221, which corresponds to the direction perpendicular to the thickness of the electronic device 10, and will not cause the size of the camera module 12 in the light incident direction to increase, which is conducive to compressing the size of the camera module 12 in the thickness direction of the electronic device 10, and is also conducive to the structural layout of the camera module 12 in the electronic device 10. At the same time, the movement stroke of the zoom lens group 123 is not easily limited by the thickness of the electronic device 10, and can provide a larger movement stroke for the zoom lens group 123, thereby increasing the zoom range of the camera module 12 and thus increasing the scope of application of the camera module 12.

[0036] Furthermore, through the reasonable design of the light deflection direction of the first conductive element 121 and the second conductive element 122, the imaging lens group 125 and the image sensor 124 are located on the same side of the first conductive element 121 and the second conductive element 122, that is, the imaging lens group 125 and the image sensor 124 partially overlap in the thickness direction of the electronic device 10, which is also conducive to compressing the size of the camera module 12 in the thickness direction of the electronic device 10, and is conducive to the spatial layout of the electronic device 10. In addition, the light-entering side of the imaging lens group 125 is arranged corresponding to the light-entering hole 111, so that the light-entering hole 111 can be arranged in a circular shape to adapt to the shape of the imaging lens group 125. Compared with the related art in which the light-entering hole corresponds to the light-entering surface of the prism, resulting in the light-entering hole being arranged in a square shape to adapt to the shape of the prism, the circular shape of the light-entering hole 111 can be better matched with other circular holes of the electronic device 10, thereby improving the aesthetics of the electronic device 10.

[0037] The first conductive element 121 and the second conductive element 122 may both be prisms made of plastic or glass, for example, triangular prisms.

[0038] In some embodiments, the camera module 12 further includes a zoom driving element 127, which can be connected to a structural member of the zoom lens group 123, such as a lens barrel that accommodates the zoom lens group 123. The zoom driving element 127 includes but is not limited to a driving element such as a voice coil motor. The zoom driving element 127 is used to drive at least a portion of the zoom lens group 123 to move along the optical axis to achieve an optical zoom function. It can be understood that the mechanism for adjusting light in the camera module 12 is divided into an imaging lens group 125 and a zoom lens group 123, and only at least a portion of the zoom lens group 123 is moved to realize the optical focusing function of the camera module 12. Compared with the related art in which the camera module has only one lens group and the driving element needs to drive the entire lens group to move, or the driving element drives the prism to move to realize zooming, it can effectively reduce the load of the zoom driving element 127, thereby facilitating the compression of the size of the zoom driving element 127, and also facilitating the simplification of the structural design of the first conductive element 121 and / or the second conductive element 122, compressing the occupied space of the first conductive element 121 and / or the second conductive element 122, and further compressing the occupied space of the camera module 12.

[0039] In some embodiments, the imaging lens group 125 includes a piezoelectric focusing element 1251, and the piezoelectric focusing element 1251 has a piezoelectric film 1252. The piezoelectric film 1252 is configured to be deformed with the change of voltage to change the focal length of the piezoelectric focusing element 1251 and realize the optical focusing function of the camera module 12. In some embodiments, the piezoelectric focusing element 1251 may also include a deformation structure 1253. The deformation structure 1253 can play a major role in adjusting light in the piezoelectric focusing element 1251, for example, it plays a role in converging or diverging light. The focal length of the piezoelectric focusing element 1251 mainly depends on the shape of the deformation structure 1253. When the piezoelectric film 1252 is deformed, it can drive the deformation structure 1253 to deform, thereby changing the focal length of the piezoelectric focusing element 1251.

[0040] By setting a piezoelectric focusing element 1251 in the imaging lens group 125 to realize the optical focusing function, compared with the related art of realizing the optical focusing function by driving the lens group to move through a voice coil motor, the setting of the voice coil motor can be saved, and there is no need to reserve a moving stroke for the imaging lens group 125, which can effectively compress the size of the camera module 12 in the thickness direction of the electronic device 10, which is beneficial to the structural layout of the electronic device 10. It can be understood that the focal length variation range required for the camera module 12 to realize the optical focusing function is small, and the focal length variation range required to realize the optical zoom function is large. Therefore, the optical focusing function is realized by setting the piezoelectric focusing element 1251 of the imaging lens group 125, which is beneficial to compressing the size of the camera module 12 and can effectively meet the focusing range requirements of the camera module 12. The optical zoom function is realized by the zoom lens group 123. The moving direction of the zoom lens group 123 is perpendicular to the thickness direction of the electronic device 10. Without increasing the size of the camera module 12 in the thickness direction of the electronic device 10, it can provide the zoom lens group 123 with sufficient moving stroke to meet the zoom range requirements of the camera module 12, so that the structural layout of the camera module 12 is reasonable and the space is fully utilized.

[0041] The piezoelectric film 1252 may include one or more piezoelectric film structures. The material of the piezoelectric film 1252 includes, but is not limited to, piezoelectric materials such as polyvinylidene difluoride (PVDF). The type of the piezoelectric focusing element 1251 is also not limited, as long as the voltage applied to the piezoelectric film 1252 is changed to deform the piezoelectric film 1252, thereby changing the focal length of the piezoelectric focusing element 1251. In some embodiments, the piezoelectric focusing element 1251 may be a liquid piezoelectric lens, and the deformable structure 1253 may include a deformable liquid, and the deformable liquid includes, but is not limited to, liquid crystal materials, silicone oils, alcohol solutions, or water. In other embodiments, the piezoelectric focusing element 1251 can also be a solid-state piezoelectric lens, and the material of the deformation structure 1253 includes but is not limited to one or more polymer resins such as alkyd resins, amino resins, nitro resins, cellulose, perchlorethylene resins, vinyl resins, acrylic resins, polyester resins, epoxy resins, polyurethane resins, silicone resins and rubber.

[0042] In some embodiments, the imaging lens group 125 is provided with at least one lens 126 with optical power in addition to the piezoelectric focusing element 1251. The lens 126 is coaxially arranged with the piezoelectric focusing element 1251 to adjust the light together. Thus, the imaging lens group 125 can reduce the burden of adjusting the light of the zoom lens group 123 while realizing the optical focusing function, which is beneficial to improving the imaging quality of the camera module 12, and reducing the number of lenses 126 of the zoom lens group 123, thereby helping to reduce the load of the zoom driving element 127 and compressing the space occupied by the zoom driving element 127.

[0043] Combination Figure 1 and Figure 3As shown, in some embodiments, the camera module 12 further includes a first anti-shake driving element 128, and the first anti-shake driving element 128 is connected to a structural member of the imaging lens group 125, for example, connected to a lens barrel accommodating the imaging lens group 125. The first anti-shake driving element 128 includes but is not limited to any applicable optical anti-shake motor such as a voice coil motor, and the first anti-shake driving element 128 is configured to drive the imaging lens group 125 to move, for example, drive the imaging lens group 125 to deflect relative to the optical axis to achieve an optical anti-shake function. The first anti-shake driving element 128 is set to drive the imaging lens group 125 to move to achieve the optical anti-shake function. Compared with the related art that realizes the optical anti-shake function by driving the prism to shake, the first anti-shake driving element 128 has a smaller load, which is also conducive to simplifying the structural design of the first conductive element 121 and the second conductive element 122, and compressing the occupied space of the first anti-shake driving element 128, the first conductive element 121 and the second conductive element 122. At the same time, the embodiment of the present application also divides the lens group into two parts: an imaging lens group 125 and a zoom lens group 123. The first anti-shake driving element 128 only needs to drive the imaging lens group 125 to move, which is also beneficial to reducing the load of the first anti-shake driving element 128, thereby facilitating the compression of the size of the first anti-shake driving element 128, and further compressing the occupied space of the camera module 12.

[0044] Please see again Figure 2 In some embodiments, the camera module 12 further includes a second anti-shake driving element 129, which is configured to drive the image sensor 124 to move, for example, to drive the image sensor 124 to deflect relative to the axis to achieve an optical image stabilization function. The second anti-shake driving element 129 is set to drive the image sensor 124 to move to achieve the optical image stabilization function. Compared with the related art in which the optical image stabilization function is achieved by driving the prism to shake, the load of the second anti-shake driving element 129 is smaller, which is conducive to compressing the size of the second anti-shake driving element 129, thereby compressing the occupied space of the camera module 12. It should be noted that only one of the first anti-shake driving element 128 and the second anti-shake driving element 129 can be set, and by driving one of the imaging lens group 125 and the image sensor 124 to move to achieve the optical image stabilization function, it is conducive to further compressing the occupied space of the camera module 12.

[0045] In some embodiments, the camera module 12 further includes a filter 131, which is disposed between the second light emitting surface 1223 and the image sensor 124. The filter 131 can filter out infrared light or other interference light to prevent the interference light from reaching the image sensor 124 and affecting normal imaging. The filter 131 can be an infrared cut-off filter 131, for example, it can be a blue glass provided with an infrared cut-off filter film. In some embodiments, when the camera module 12 is provided with a second anti-shake driving element 129 to drive the image sensor 124 to move, the filter 131 can be fixed relative to the image sensor 124, and the second anti-shake driving element 129 can drive the image sensor 124 to move synchronously with the filter 131. For example, the image sensor 124 and the filter 131 are fixed on a unified structural member, and the second anti-shake driving element 129 is used to drive the structural member carrying the image sensor 124 and the filter 131 to move. With such arrangement, when the image sensor 124 is driven to move to realize the optical image stabilization function, the filter 131 can move synchronously with the image sensor 124, so that the incident angle of the light passing through the filter 131 on the image sensor 124 is always adapted to the image sensor 124, thereby preventing the light from being difficult to be received by the image sensor 124 due to the relative inclination of the filter 131 and the image sensor 124 due to the large incident angle, which is conducive to maintaining the good imaging quality of the camera module 12 during the image stabilization process. Of course, in other embodiments, the filter 131 can also be arranged between the first light emitting surface 1213 of the first conductive element 121 and the second light incident surface 1221 of the second conductive element 122, so that the filter 131 does not occupy the size of the camera module 12 in the thickness direction of the electronic device 10, which is conducive to compressing the size of the camera module 12 in the thickness direction of the electronic device 10.

[0046] refer to Figure 2 As mentioned above, in some embodiments, each lens 126 in the zoom lens group 123 can be fixed in the same lens barrel, and the zoom driving element 127 can drive the entire zoom lens group 123 to move to achieve an optical zoom function. Figure 4 As shown, in other embodiments, the zoom lens group 123 includes a first lens group 1231 and a second lens group 1232, and the first lens group 1231 and the second lens group 1232 are sequentially spaced in a direction from the first light exit surface 1213 to the second light incident surface 1221, and the zoom driving element 127 can drive at least one of the first lens group 1231 and the second lens group 1232 to move along the optical axis to achieve a zoom function. The zoom lens group 123 may also include a larger number of lens groups, and the zoom driving element 127 can drive any lens group in the zoom lens group 123 to move. When the zoom driving element 127 only drives one of the lens groups in the zoom lens group 123 to move to achieve a zoom function, it is beneficial to reduce the load of the zoom driving element 127, compress the size of the zoom driving element 127, and thus compress the occupied space of the camera module 12. For example, referring to Figure 4 As shown, in some embodiments, the first lens group 1231, the first conductive element 121, and the second conductive element 122 are relatively fixed, and the zoom driving element 127 can drive the second lens group 1232 to move between the first lens group 1231 and the second conductive element 122 to meet the needs of different zoom ranges. Of course, in other embodiments, when the zoom lens group 123 includes multiple lens groups, the camera module 12 may also include multiple zoom driving elements 127 to drive different lens groups to move respectively, realize the function of multi-stage zoom, improve the zoom range of the camera module 12, and improve the applicability of the camera module 12.

[0047] It should be noted that in the present application, the number and type of lenses 126 in the imaging lens group 125, the number of lens groups in the zoom lens group 123, and the number and type of lenses 126 in each lens group are not limited, and can be specifically set according to the focus, zoom requirements and imaging quality requirements of the camera module 12.

[0048] In some embodiments, the first light incident surface 1211 and the second light emitting surface 1223 are coplanar, the first light emitting surface 1213 is perpendicular to the first light incident surface 1211, the second light incident surface 1221 is perpendicular to the second light emitting surface 1223, the first reflective surface 1212 is inclined to the first light incident surface 1211 and the first light emitting surface 1213, and the second reflective surface 1222 is inclined to the second light incident surface 1221 and the second light emitting surface 1223. For example, the first reflective surface 1212 and the first light incident surface 1211 and the first light emitting surface 1213 are at an angle of 45°, and the second reflective surface 1222 and the second light incident surface 1221 and the second light emitting surface 1223 are at an angle of 45°.

The processor 508 executes various functional applications and data processing by running the applications stored in the memory 502. The memory 502 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the electronic device 10 (such as audio data, a phone book, etc.), etc. In addition, the memory 502 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory 502 can also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0052] The input unit 503 can be used to receive input digital, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touch pad, can collect user touch operations on or near it (such as operations performed by users using fingers, styluses, or any other suitable objects or accessories on or near the touch-sensitive surface), and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, 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 touch point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508.

[0053] The display unit 504 can be used to display information input by the user or information provided to the user and various graphical user interfaces of the electronic device 10, which can be composed of graphics, text, icons, videos and any combination thereof.

Furthermore, the touch-sensitive surface may cover the display panel, and when the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event, and then the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in Figure 5 In the embodiment, the touch sensitive surface and the display panel are used as two independent components to implement input and output functions, but in some embodiments, the touch sensitive surface and the display panel can be integrated to implement input and output functions. It can be understood that the display screen 110 can include an input unit 503 and a display unit 504.

[0054] The electronic device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors.

As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It 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 pedometer, tapping), etc.; as for other sensors that the electronic device 10 can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0055] The audio circuit 506 can provide an audio interface between the user and the electronic device 10 through a speaker and a microphone. The audio circuit 506 can convert the received audio data into an electrical signal, transmit it to the speaker, and convert it into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and converted into audio data, and then the audio data is output to the processor 508 for processing, and then sent to another electronic device 10 through the radio frequency circuit 501, or the audio data is output to the memory 502 for further processing. The audio circuit 506 may also include an earphone socket to provide communication between an external earphone and the electronic device 10.

[0056] Wireless Fidelity (WiFi) is a short-range wireless transmission technology. The electronic device 10 can help users send and receive emails, browse web pages, and access streaming media through the wireless fidelity module 507, which provides users with wireless broadband Internet access. Figure 5 The wireless fidelity module 507 is shown, but it is understandable that it is not a necessary component of the electronic device 10 and can be omitted as needed without changing the essence of the invention.

[0057] The processor 508 is the control center of the electronic device 10. It uses various interfaces and lines to connect various parts of the entire electronic device 10. By running or executing applications stored in the memory 502 and calling data stored in the memory 502, it executes various functions of the electronic device 10 and processes data, thereby monitoring the electronic device 10 as a whole. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 508.

[0058] The electronic device 10 also includes a power supply 509 for supplying power to various components. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, so that the power management system can manage charging, discharging, and power consumption. The power supply 509 can also include one or more DC or AC power supplies, recharging systems, power failure detection circuits, power converters or inverters, power status indicators, and other arbitrary components.

In specific implementation, the above modules can be implemented as independent entities, or can be arbitrarily combined and implemented as the same or several entities. The specific implementation of the above modules can refer to the previous method embodiment, which will not be described in detail here.

[0060] The technical features of the above-described embodiments may be arbitrarily combined.
