The rear cover 240 and the middle frame 220 are fixedly connected to form a receiving cavity 220 for receiving devices of the electronic apparatus 20, such as a battery, a circuit board 600, etc., so that the rear cover 240 can be covered on the middle frame 220 to cover the battery, the circuit board 600, etc. It can be understood that the display screen 100 and the rear cover 240 are disposed on two opposite sides of the middle frame 220, the display screen 100 may be disposed on the display surface of the middle frame 220 to display a picture, and in particular, the display screen 100 may be used to display a preview image of an object to be photographed, which is acquired by the camera.
The middle frame 220 may have a plurality of sides 222, and the plurality of sides 222 of the middle frame 220 are all located on the periphery of the base of the middle frame 220. The lengths of the sides 222 of the middle frame 220 may be the same or different. Such as the middle frame 220, may have a long side with a longer length and a short side with a shorter length, i.e., the length of the long side is greater than the length of the short side. Wherein the long sides can include a first side 2227 and a second side 2228. At least one touch module 400 is disposed on each of the first side 2227 and the second side 2228, for example, the first side 2227 is provided with a first touch module 401, and the second side 2228 is provided with a second touch module 402, so that the touch operations of the user on the first side 2227 and the second side 2228 can be determined by the corresponding touch modules 400 on the first side 2227 and the second side 2228, and the touch modules 400 are further configured to receive corresponding touch signals.
It should be noted that the touch module 400 may also be disposed on the side 222 with a shorter length. It is understood that, when the lengths of the side edges 222 are the same, the touch module 400 can be disposed on any one of the side edges 222 or any plurality of the side edges 222. It is also understood that the touch module 400 can be disposed at a connecting position of the two connecting sides 222, or at a corner position of the middle frame 220. It is also understood that one or more touch modules 400 may be disposed on one of the side edges 222. In some embodiments, corresponding touch areas 2222 may be disposed on the first side 2227 and the second side 2228, so as to determine a focusing mode of the camera 800 according to a touch operation of the touch areas. Of course, it is also possible to arrange the touch module 400 at all positions of the side 222, that is, the touch area 2222 is the entire side 222.
In some embodiments, a self-luminous material may be disposed at the location of touch area 2222 so that the user can identify touch area 2222. The color setting at the position of the touch area 2222 may be different from the color setting at other positions of the side 222. A light emitting lamp may be further disposed in the touch area 2222.
In the related art, a plurality of physical keys, such as an on-off key, a volume key, a shortcut key, etc., are disposed on a side of the electronic device. The physical keys generally protrude out of the side edges, and gaps are formed between the physical keys and the side edges of the electronic equipment, so that water leakage and dust entering are easy to occur.
Based on this, in the embodiment of the application, the touch module 400 is disposed on the inner surfaces of the first side 2227 and the second side 2228, and the user can directly operate the touch area 2222 to control the touch module 400. The integrity of the side edges 222 may be maintained, and the electronic device 20 may be made waterproof and dustproof.
The side 222 can be provided with a first receiving groove 2224 for receiving and operating the touch module 400. The first receiving groove 2224 may communicate with the receiving cavity 260. The depth of the first receiving groove 2224 may be much greater than the thickness of the touch module 400, that is, after the touch module 400 is placed in the first receiving groove 2224, a hollow cavity is formed at a position where the first receiving groove 2224 is communicated with the receiving cavity 260, so that the touch area 2222 at the position of the first receiving groove 2224 is deformed. Such as: the distance between the touch module 400 and the receiving cavity 260 is about 5 mm. The length of the first receiving groove 2224 is the distance of the first receiving groove 2224 along the length direction of the side 222, and the length of the first receiving groove 2224 can be determined according to actual requirements. The width of the first receiving groove 2224 is a distance along the width direction of the side 222, and the width of the first receiving groove 2224 may be between 1.6 mm and 2 mm.
The outer surface of the side 222 may be of various shapes, such as: arc, rectangular, rounded rectangular, etc. The outer surface of the side 222 may also be curved. At least one of the rear cover 240 and the display screen 100 may be arranged in an arc shape and cover at least a portion of the side edge 222.
The touch module 400 is disposed in the touch area 2222 and disposed on the inner surfaces of the first side 2227 and the second side 2228. The touch module 400 can be electrically connected to the circuit board 600 of the electronic device 20. The circuit board 600 of the electronic device 20 may have integrated thereon a processor, a memory, etc., which may be used to process various operations of the electronic device 20. Such as: the processor may control a focusing mode of the camera 800 in the electronic device 20, and the touch module 400 may receive a corresponding touch signal in the touch area 2222, where the touch signal may be a signal for controlling the camera 800 to enter the first focusing mode, the touch signal may be a signal for controlling the camera 800 in the electronic device 20 to perform a photographing operation, and the control signal may be a signal for adjusting a photographing parameter of the camera 800.
In the embodiment of the application, the touch module 400 is disposed on the inner surfaces of the first side 2227 and the second side 2228, and the first side 2227 and the second side 2228 are not provided with the hole structures for avoiding the touch module 400, so that a user can drive the touch module 400 through the side 222 at the position of the touch area 2222 and the control signal to control the electronic device 20, such as controlling the electronic device 20 to determine the focusing mode of the camera 800, controlling the electronic device 20 to perform the photographing operation, and adjusting the photographing parameters of the camera 800.
It should be noted that the focusing modes of the camera include a first focusing mode and a second focusing mode, the first focusing mode is a manual focusing mode, the second focusing mode is an automatic focusing mode, the automatic focusing mode is a preset focusing mode, when the camera is turned off and then is turned on again, the focusing mode when the camera is turned on again is a default second focusing mode, that is, the automatic focusing mode, and when the touch modules of the multiple touch areas receive the first touch signal at the same time, the camera is controlled to enter the first focusing mode according to the multiple touch signals, that is, the focusing mode of the camera is controlled to be switched from the second focusing mode to the first focusing mode.
When the focusing mode of the camera is determined to be the manual focusing mode, because the focus position of the camera in the manual focusing mode is the fixed focus position, the fixed focus position cannot be changed due to the movement of the electronic equipment or the change of the object position in the camera view frame, that is, when the camera is in the first focusing mode, only when a received refocusing instruction is received, such as a user performs touch operation on a display screen or a touch module receives a corresponding focusing touch signal, the fixed focus position can be adjusted by moving the position of the camera lens to realize refocusing.
When the focusing mode of camera confirms for the auto focus mode, when the image of the object of waiting to shoot that the camera acquireed, the lens that camera module in just can drive the camera moves from the bottom to the top, and at this in-process, pixel sensor will carry out the comprehensive detection in the depth direction to whole scene scope to contrast numerical value such as contrast is continuously recorded. After the position with the maximum contrast is found, the lens moving to the top returns to the position again, and the final automatic focusing process is completed.
It can be understood that, when the camera is in the automatic focusing mode to take a picture, if the position of the object in the viewing frame, the content of the picture and the light of the picture are changed, the electronic device needs to automatically focus again, and when the electronic device is in the motion state, the electronic device carries out continuous focusing due to the position change of an object in the viewfinder, and the image of the object to be shot acquired by the camera is not clear enough due to the movement of the lens position of the camera in the continuous focusing process, namely, when the electronic device is in a motion state, it is inconvenient for the user to acquire a high-quality image when the camera is in the auto-focus mode, so when the user cannot acquire a high-quality image in the auto-focus mode, the automatic focusing mode can be quickly switched to the manual focusing mode for shooting through touch operation on the touch area, so that a user can conveniently and quickly switch the focusing mode of the camera.
Referring to fig. 3, fig. 3 is a schematic view illustrating a first structure of a touch module in the electronic device shown in fig. 2. The touch module 400 may include an ultrasonic detection module 410, and the ultrasonic detection module 410 may include a first flexible circuit board 412, a signal transmitting part 414, and a signal receiving part 416. The signal emitting portion 414 and the signal receiving portion 416 are electrically connected to the first flexible circuit board 412. The signal emitting portion 414 and the signal receiving portion 416 may both be made of a piezoelectric ceramic material. The first flexible circuit board 412 may be disposed on an inner surface of the side 222 of the touch area 2222, and is adhered to the inner surface of the side 222, such as by glue, double-sided tape, or the like. The ultrasonic detection module 410 may receive different touch signals, such as different operation modes, and may determine the touch signal through the operation modes to control the camera 800 of the electronic device 20 according to the touch signal.
The ultrasonic detection module 410 can detect the pressed position of the touch area 2222 to achieve positioning. Or the ultrasonic detection module 410 may detect a specific position for placing a finger on the touch area 2222, so as to achieve positioning of touch operation, specifically, when the ultrasonic detection module 410 detects a pressing acting force at a preset position, the ultrasonic detection module 410 may receive a pressing touch signal, determine the pressing touch signal as a first touch signal, and when the ultrasonic detection module 410 detects that the ultrasonic modules 410 on the first side 2227 and the second side 2228 receive the first touch signal at the same time, convert the first touch signal into an electrical signal and transmit the electrical signal to the processor of the circuit board 600, and the processor may control the camera 800 to enter the first focus mode according to the first touch signal.
In some embodiments, after the camera 800 is in the first focus mode, the processor may acquire a focus position of the camera 800, determine the focus position as a fixed focus position in the first focus mode, and simultaneously display the fixed focus position on the preview image of the display screen 100, so as to facilitate a user to adjust a position of a shooting subject in an object to be shot in real time through the focus position on the display screen 100, and move the shooting subject to an area coinciding with the focus position, so as to facilitate shooting by the user. It is understood that, when the electronic device receives a focusing instruction, the processor may further adjust the fixed focus position according to the focusing instruction, so as to implement a refocusing operation of the camera.
In some embodiments, when the pressing force detected by the ultrasonic detection module 410 continuously moves after the camera 800 is in the first focusing mode, or when it is detected that the finger of the user performs a sliding operation on the touch area 2222, the ultrasonic detection module 410 may receive the sliding operation signal, convert the sliding operation signal into an electrical signal, and transmit the electrical signal to the processor of the circuit board 600, and the processor adjusts the fixed focus position of the camera 800 according to the sliding operation signal, so as to achieve a refocusing operation of the camera.
For example, when the ultrasonic sensor 410 located at the first side 2228 receives the sliding operation signal, the sliding operation signal may be determined as a second touch signal, the second touch signal may be converted into an electrical signal and transmitted to the processor of the circuit board 600, and the processor may adjust the focal position of the camera according to the second touch signal. The sliding operation may be an operation along the length of the side edge or along the width direction of the side edge, and when the sliding operation along the length of the side edge is detected, the position of the fixed focus on the display screen may be controlled according to the sliding distance and the sliding direction of the sliding operation and adjusted accordingly along the sliding direction. Or when the sliding operation along the width of the side edge is detected, the position of the fixed focus on the display screen can be controlled according to the sliding distance and the sliding direction of the sliding operation to be correspondingly adjusted along the sliding direction.
In some embodiments, after the camera 800 enters the first focusing mode, when the pressing force detected by the ultrasonic detection module 410 continuously moves, or when it is detected that the finger of the user performs a sliding operation on the touch area 2222, the ultrasonic detection module 410 may receive the sliding operation signal, convert the sliding operation signal into an electrical signal, and transmit the electrical signal to the processor of the circuit board 600, and the processor adjusts the shooting parameters of the camera 800 according to the sliding operation signal.
For example, when the ultrasonic sensor 410 located on the first side 2227 receives the sliding operation signal, the sliding operation signal may be determined as a third touch signal, the third touch signal may be converted into an electrical signal and transmitted to the processor of the circuit board 600, and the processor may adjust the shooting parameters of the camera according to the third touch signal. The shooting parameters of the camera include a shooting mode, a shutter speed, an aperture parameter, a focal length parameter, a sensitivity parameter, a white balance parameter, an exposure parameter and the like. Further, the shooting mode may include a portrait mode, a night view mode, an outdoor mode, a macro mode, a wide-angle mode, a self-timer mode, a panorama mode, a slow lens mode, and the like, the processor may adjust one of the plurality of shooting parameters of the camera according to the third touch signal, and similarly, the processor may simultaneously adjust a plurality of shooting parameters according to the third touch signal. For example, the processor may adjust a focal length parameter of the camera according to the third touch signal. Or, the processor simultaneously adjusts the shooting mode and the sensitivity parameter of the camera according to the third touch signal, and if the shooting mode of the camera is switched from the outdoor mode to the night view mode according to the third touch signal, the processor correspondingly adjusts the sensitivity parameter according to the third touch signal, that is, the sensitivity parameter is correspondingly increased, so that the shooting requirement in the night view mode is met.
Further, the sliding operation is an operation of sliding along the length direction or the width direction of the side, specifically, the sliding operation along the length direction of the side may be an operation of sliding from the center position of the ultrasonic detection module 410 to the end portion along the length direction of the side, where the ultrasonic detection module 410 includes a first end portion, a center portion and a third end portion, and the center portion is the center of the touch module 400 along the length direction of the side. When the user's finger slides from the center position to the first end along the touch module 400, one or more parameter values among the shutter speed, the aperture parameter, the focal length parameter, the sensitivity parameter, the white balance parameter, and the exposure parameter of the camera can be increased, and when the user's finger slides from the center position to the third end along the touch module 400, one or more parameter values among the shutter speed, the aperture parameter, the focal length parameter, the sensitivity parameter, the white balance parameter, and the exposure parameter of the camera can be decreased.
The sliding operation in the lateral width direction may be an operation of sliding the center position of the ultrasonic detection module 410 toward the non-display surface in the lateral width direction, or an operation of sliding the center position of the ultrasonic detection module 410 toward the display surface in the lateral width direction. When the user's finger slides from the center position to the side of the display surface along the touch module 400, the electronic device 20 can be controlled to select the next shooting mode, and when the user's finger slides from the center position to the side of the non-display surface along the touch module 400, the electronic device 20 can be controlled to return to the previous shooting mode.
It is understood that the ultrasonic detection module 410 may also detect other operations, such as a tap operation. The ultrasonic detection module 410 may also control other functions of the electronic device 20 according to other operations or different sliding operations.
It is understood that a signal emitting portion 414 and a signal receiving portion 416 may be disposed at an interval on the ultrasonic detection module 410. A plurality of signal transmitting sections 414 and a plurality of signal receiving sections 416 may be provided at intervals.
Referring to fig. 4, fig. 4 is a schematic view illustrating a second structure of a touch module in the electronic device shown in fig. 2. The touch module 400 may include a pressure detection module 420, and the pressure detection module 420 may include a second flexible circuit board 422 and a pressure detector 424 electrically connected to the second flexible circuit board 422. The second flexible circuit board 422 may be disposed on an inner surface of the side 222, such as by being adhered to the inner surface of the side 222 with glue, double-sided tape, or the like. The width of the first receiving groove 2224 may be about 1.6 mm or about 2 mm.
The pressure detector 424 may include a resistive sensor or a capacitive sensor, among others. It should be noted that when the pressure detector 424 includes a capacitive sensor, no metal is disposed at the position of the pressure detector 424 to ensure the accuracy of the detection of the capacitive sensor. The resistive sensor may be a MEMS (micro electro Mechanical Systems) sensor, which requires the width of the first receiving groove 2224 to be 1.6 mm. The resistive sensor is not limited to the MEMS piezoresistive IC, and the resistive sensor may be a strain gauge, and the strain gauge needs to have a width of the first receiving groove 2224 of about 2 mm.
It is understood that the side 222 is thin and deformable by the pressing force, and the second flexible circuit board 422 and the pressure detector 424 are disposed on the inner surface of the side 222. When the side 222 is pressed, the side 222 deforms, and drives the second flexible circuit board 422 and the pressure detector 424 to deform together, and converts the pressure into an electrical signal to be transmitted to the processor of the circuit board 600, and the processor can control the display scale of the input frame on the display screen of the electronic device 20 according to the pressing operation. And when the processor detects that the pressing force of the pressing operation is greater than a preset value, judging that the pressing operation is effective pressing operation, and adjusting the display scale of the input frame currently displayed on the display screen according to the pressing operation. The pressing operation may include one pressing, how many presses, long pressing, and the like. The long press is that the press duration exceeds the preset duration. The pressing down may be a pressing operation detected a plurality of times within a preset time.
In some embodiments, after the pressure detection module 420 detects the pressing operation, the pressing strength is obtained and sent to the processor, when the processor determines that the pressing operation is an effective pressing operation according to the pressing strength, the number of times of the effective pressing operation within a preset time duration may also be obtained, and when the number of times is greater than the preset number of times, the display ratio of the input frame currently displayed on the display screen is adjusted.
It should be noted that, in the actual assembly process, since the second flexible circuit board 422 is made of a soft material, deformation is easily generated, and in order to reduce the deformation of the second flexible circuit board 422 in the assembly process, the thickness of the second flexible circuit board 422 may be increased. Of course, a reinforcing plate may be fixedly connected to the second flexible circuit board 422.
Referring to fig. 5, fig. 5 is a schematic view illustrating a third structure of a touch module in the electronic device shown in fig. 2. The touch module 420 may further include a reinforcing sheet 426, the reinforcing sheet 426 is fixedly connected to the second flexible circuit board 422, and the reinforcing sheet 426 and the pressure detector 424 are respectively disposed on two sides of the second flexible circuit board 422. The reinforcing sheet 426 is fixedly connected to the inner surface of the side 222 at the position of the touch area 2222. The reinforcing plate 426 may increase the overall strength of the pressure detecting module 420 for assembly, thereby preventing deformation during assembly and difficulty in assembly. It should be noted that the pressure detector 424 and the reinforcing sheet 426 may not be provided on both sides of the first flexible circuit board 426.
Referring to fig. 6, fig. 6 is a schematic diagram illustrating a fourth structure of a touch module in the electronic device shown in fig. 2. The reinforcing sheet 426 and the pressure detector 424 may be disposed on the same side of the second flexible circuit board 422, the pressure detector 424 may be disposed within a gap 428 of the reinforcing sheet 426, and the space of the gap 428 is larger than the size of the pressure detector 424. Such as the thickness of the reinforcing sheet 426 is greater than the thickness of the pressure detector 424, the reinforcing sheet 426 and the pressure detector 424 do not touch. Therefore, the pressure detector 424 is ensured not to contact with the reinforcing sheet 426 or the side edge 222 when being deformed by the pressure, so that the accuracy of the pressure detector 424 for detecting the pressing force is affected.
It will be appreciated that in order for the pressure detector 424 to be able to effectively detect pressure, a void 428 may be provided in the reinforcing sheet 426, with the pressure detector 424 being spatially located within the void 428. Therefore, when the side 222 of the touch area 2222 receives an applied force, the stress of the applied force is applied to the pressure detector 424 at the position of the gap 428 due to the arrangement of the reinforcing sheet 426, so that the signal detected by the pressure detection module 420 can be more accurate. In some embodiments, two reinforcing sheets 426 may be connected to the second flexible circuit board 422 to form the gap 428, or a gap 428 may be opened on one reinforcing sheet 426.
It should be noted that, without the enhancement sheet 426, the accuracy of the signal detected by the pressure detection module 420 may also be improved, such as disposing a groove on the side 222 of the touch area 2222 to dispose the pressure detector 424 in the groove, so that the thickness of the two sides of the groove is larger, and thus the thickness of the position of the pressure detector 424 is smaller and is also easy to deform.
It should be noted that the pressure detection module 420 may also detect other operations, such as a sliding operation. The pressure detection module 420 may determine that it is continuously moving based on the pressure it detects. When the pressure detection module 420 detects a sliding operation and sends the sliding operation signal to the processor, the processor may control the size of the input frame currently displayed on the display screen according to the sliding operation signal.
It should be noted that the touch module 400 is not limited to the ultrasonic detection module 410, nor to the pressure detection module 420. In some embodiments, the touch module 400 may include a pressure detection module and an ultrasonic detection module. Such as disposing the pressure detector, the ultrasonic-wave signal transmitting section, and the ultrasonic-wave signal receiving section on the same flexible circuit board. For example: a pressure detector is disposed between a signal transmitting portion and a signal receiving portion. Of course, if the pressure detector is plural, each pressure detector is disposed between one signal transmitting portion and one signal receiving portion. Touch module 400 includes pressure detector promptly, includes ultrasonic detector again, can effectively detect the pressure degree through pressure detector, can effectively detect the position of pressing through ultrasonic detector.
It should be noted that the electronic device 20 may further include one or more ultrasonic detectors and one or more pressure detectors in different touch areas 2222.
It is understood that, when the touch module 400 includes the ultrasonic detector and the pressure detector, the arrangement manner is not limited thereto.
