Before explaining the electronic device provided by the embodiment of the present application, an application scenario of the electronic device provided by the embodiment of the present application is specifically explained:

with the demand of users for large display screens and portability of electronic devices, foldable electronic devices (e.g., foldable screen mobile phones, notebook computers, tablet computers, etc.) are increasingly popular among users. In the prior art, in order to make the electronic device be in a stable folded state after being folded, the stable folding of the electronic device can be realized by adopting a buckle, a magnetic attraction mode and the like. When the electronic device needs to be unfolded from the folded state to the unfolded state, a user is generally required to apply a force or a magnetic attraction force to the electronic device to overcome the buckle, so that the operation convenience of the user is reduced. In order to overcome the above problems, in the related art, a motor capable of providing an opening/closing force is added to the electronic device, or a magnetic member is displaced, and the polarity of the magnetic member is changed, so that the electronic device is automatically switched between the unfolded state and the folded state. However, the above-mentioned method not only causes the size of the electronic device to be larger, which is not favorable for the light and thin design of the electronic device, but also the displacement of the magnetic member may cause the magnetic field in the electronic device to change, which further causes the magnetically sensitive components in the electronic device to be affected, which affects the use effect of the electronic device and affects the user experience.

Based on the foregoing problem, an embodiment of the present application provides an electronic device, which includes: the device comprises a first device main body, a second device main body and a pneumatic telescopic mechanism; the first device body and the second device body are rotatably connected to switch the electronic device between an unfolded state and a folded state; at least one of the first equipment main body and the second equipment main body is provided with a first sound cavity, and the first sound cavity is a closed sound cavity positioned on one side of the loudspeaker; the pneumatic telescopic mechanism is arranged on the target equipment main body and communicated with the first sound cavity to form a closed airflow channel; the target device body includes: the first device body and/or the second device body; under the condition that electronic equipment is in fold condition, the speaker lets in preset current to make the vibrating diaphragm vibration of speaker forms the drive air current, the drive air current drive at least a part of pneumatic telescopic machanism stretches out the target device main part, so that electronic equipment withdraws from fold condition.

In the embodiment of the application, the driving airflow formed by vibrating diaphragm vibration of the loudspeaker is used as the driving force of the pneumatic telescopic mechanism, so that the electronic equipment can rapidly exit from a folded state, the utilization rate of the loudspeaker is improved, the problem that the driving piece used for unfolding the electronic equipment is independently arranged in the electronic equipment to cause the volume of the electronic equipment is solved, the electronic equipment can be more light and thinner, and the use experience of a user can be effectively improved.

In the embodiment of the present application, the electronic device includes, but is not limited to, a folding screen mobile phone, a folding notebook computer, a folding tablet computer, an electronic book, a learning machine, and the like.

The electronic device provided in the embodiments of the present application is described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1, a schematic structural diagram of an electronic device in an unfolded state according to an embodiment of the present application is shown. Referring to fig. 2, a schematic structural diagram of an electronic device in a folded state according to an embodiment of the present application is shown.

As shown in fig. 1 and fig. 2, in the embodiment of the present application, the electronic device may specifically include: a first apparatus body 10, a second apparatus body 20, and a pneumatic telescoping mechanism 30; the first apparatus body 10 and the second apparatus body 20 are rotatably connected to switch the electronic apparatus between the unfolded state and the folded state; at least one of the first apparatus body 10 and the second apparatus body 20 is provided with a first sound chamber 42, the first sound chamber 42 being a closed sound chamber located on the side of the speaker 40; the pneumatic telescoping mechanism 30 is arranged on the target equipment main body, and the pneumatic telescoping mechanism 30 is communicated with the first sound cavity 42 to form a closed airflow channel; the target device main body includes: the first apparatus body 10 and/or the second apparatus body 20; under the condition that the electronic device is in the folded state, a preset current is supplied to the loudspeaker 40, so that the vibrating diaphragm 41 of the loudspeaker 40 vibrates to form a driving airflow, and the driving airflow drives at least one part of the pneumatic telescopic mechanism 30 to extend out of the target device body, so that the electronic device is taken out of the folded state. In the embodiment of the present application, the driving airflow formed by vibrating the vibrating diaphragm 41 of the speaker 40 is used as the driving force of the pneumatic telescopic mechanism 30, so that the electronic device can not only exit from the folded state quickly, but also the utilization rate of the speaker 40 is improved, the problem that the driving part used for unfolding the electronic device is separately arranged in the electronic device to cause the volume of the electronic device is avoided, and further the electronic device can be made thinner and lighter.

It should be noted that, the speaker 40 is disposed in the electronic device, and sound cavity structures are formed on both sides of the diaphragm 41, where the sound cavity structure on one side is communicated with the outside through a sound outlet channel and may be referred to as a front sound cavity, and the sound cavity structure on the other side is a sealed sound cavity, which has a better sealing performance and may be referred to as a rear sound cavity, and in this embodiment, the first sound cavity 42 may be referred to as a rear sound cavity. In the embodiment of the present application, the first sound cavity 42 is a sealed sound cavity structure with better sealing performance when not communicating with the pneumatic telescoping mechanism 30. In practical applications, the structure of the speaker 40 forming the first sound cavity 42 on the electronic device may be various, for example, a circuit board and a circuit board support form an accommodating cavity, the speaker 40 is disposed in the accommodating cavity to divide the accommodating cavity into a front sound cavity and a rear sound cavity (the first sound cavity 42), and in this embodiment, a specific structural manner of the first sound cavity 42 is not limited.

In the embodiment of the present application, the first device body 10 and the second device body 20 may serve as structural bodies in the electronic device for supporting various functional components of the electronic device. The structural implementation of the rotatable connection between the first device body 10 and the second device body 20 of the electronic device may be various. For example, the first apparatus body 10 and the second apparatus body 20 are rotatably connected by a rotating shaft (folding shaft), so that the second apparatus body 20 is folded together between the first apparatus body 10 to a folded state by rotation, or spliced to an unfolded state in the same plane.

In the embodiment of the present application, the electronic device includes, but is not limited to, an electronic device that is folded by a magnetic attraction force of a magnetic member, a hinge force of a hinge, or a latching force of a buckle. As shown in fig. 1 to 4, in the embodiment of the present application, the electronic device is taken as an example to realize a folded state through the magnetic attraction force of the magnetic member 50, and the specific structure and the operation principle of the electronic device are exemplarily described, and other references may be performed.

In the embodiment of the present application, the pneumatic telescoping mechanism 30 may be understood as a mechanism that can be driven by an air flow to achieve telescoping, and the pneumatic telescoping mechanism 30 is used to provide a driving force for the electronic device to exit from the folded state. In the embodiment of the present application, when the speaker 40 is powered by a predetermined current, the diaphragm 41 will vibrate to generate a driving airflow, and the pneumatic telescoping mechanism 30 will expand (extend or contract) under the driving airflow. In the embodiment of the present application, the deformation of the pneumatic telescoping mechanism 30 during extension is mainly used to enable the electronic device to exit from the folded state.

It should be noted that the preset current passed through the speaker 40 is different from the working current when the speaker 40 works as a sound device, and in the embodiment of the present application, the preset current may be greater than the working current of the speaker 40 (i.e., the working current when playing sound). In practical applications, when the speaker 40 is in a normal sound reproduction state, a small current is supplied to realize the vibration and sound production of the diaphragm 41 of the speaker 40; when it forms drive airflow to need the vibration of speaker 40 vibrating diaphragm 41, can let in great electric current to make speaker 40 when great electric current circulates, vibrating diaphragm 41's vibration range is bigger, and then forms stronger drive airflow, and drive airflow can drive pneumatic telescopic machanism 30 and extend the deformation, so that electronic equipment withdraws from fold condition. In the embodiment of the application, the control through the loudspeaker 40 is simpler and more reliable, and the difficulty in controlling the electronic equipment to exit from the folded state can be effectively reduced.

In this application embodiment, vibrating diaphragm 41 through speaker 40 vibrates and produces the drive air current, on the one hand, can promote speaker 40's utilization ratio, on the other hand can control the size of drive air current through the electric current of control speaker 40 input, make electronic equipment withdraw from fold condition's control circuit simple reliable easy control more, the drive air current that vibrating diaphragm 41 vibrates and produces is as the drive power that drive electronic equipment withdraws from fold condition, can effectively avoid electronic equipment to be flicked and lead to the quick drastic change of complete machine atress to the harm of screen, and then can effectively promote electronic equipment's use reliability and life.

In the embodiment of the present application, the pneumatic telescoping mechanism 30 may be separately provided on the first apparatus main body 10 or the second apparatus main body 20, or the pneumatic telescoping mechanism 30 may be provided on both the first apparatus main body 10 and the second apparatus main body 20. It is to be understood that, in the case where the pneumatic telescoping mechanism 30 is provided in the first apparatus body 10, the first apparatus body 10 is a target apparatus body, and in the case where the pneumatic telescoping mechanism 30 is provided in the first apparatus body 10 and the second apparatus body 20, both the first apparatus body 10 and the second apparatus body 20 are target apparatus bodies.

In the embodiment of the present application, the pneumatic telescoping mechanism 30 and the first sound chamber 42 may be disposed on different device bodies, so as to simplify the internal layout of the electronic device. Specifically, the first apparatus body 10 and the second apparatus body 20 are provided with the pneumatic telescoping mechanism 30 on one and the first sound chamber 42 on the other. Or, the pneumatic telescopic mechanism 30 and the first sound cavity 42 may also be disposed on the same device main body, so that the airflow channel may be shorter, thereby reducing the difficulty of the layout of the airflow channel in the electronic device.

Specifically, the pneumatic telescoping mechanism 30 includes a telescoping portion 31, a mounting hole communicated with the airflow channel is provided on a first side surface of the target device main body, and the telescoping portion 31 is provided in the mounting hole; the first side is a side of the electronic apparatus opposite to the first apparatus body 10 and the second apparatus body 20 when the electronic apparatus is in the folded state; under the driving of the driving airflow, the telescopic part 31 extends out of the mounting hole, so that the electronic device exits the folded state. In practical applications, the telescopic portion 31 may be disposed near a side edge of the target apparatus body; the telescopic part 31 is extended out of the first side surface of the target apparatus body or retracted into the target apparatus body by the driving of the driving air flow. It is to be understood that, in the case where the first apparatus body 10 is a target apparatus body, the first side face is a side face of the first apparatus body 10 opposite to the second apparatus body 20 in the folded state. When the second apparatus body 20 is the target apparatus body, the first side surface is a side surface of the second apparatus body 20 facing the first apparatus body 10 in the folded state.

In the embodiment of the application, through utilizing the flexible characteristic of portion 31 under the drive of drive air current to make electronic equipment can withdraw from fold condition fast, structure and principle are simple, and maneuverability is high, can effectively avoid electronic equipment additionally to increase other devices, has saved electronic equipment inner space, is favorable to electronic equipment frivolousization.

In the embodiment of the present application, the fact that the stretchable part 31 is disposed near the side edge of the target apparatus main body may also be understood that the stretchable part 31 is near the circumferential side edge of the electronic apparatus. For example, when the electronic device has a frame structure, the extendable portion 31 is disposed on the peripheral side of the frame structure, so that the extendable portion 31 can not only avoid occupying the area of the display screen of the electronic device, but also make full use of the frame structure to reduce the difficulty in the installation layout of the extendable portion 31.

It is understood that, since the electronic apparatus is caused to exit the folded state by utilizing the characteristic of the expansion and contraction portion 31 in the embodiment of the present application, the electronic apparatus is more easily exited from the folded state when the expansion and contraction portion 31 is provided at the side edge of the target apparatus main body opposite to (or parallel to) the folding axis. The folding axis is a rotation axis (may be a non-solid axis) when the electronic device is folded.

In the embodiment of the present application, the expansion portion 31 may be an elastic member having an inner cavity, and the inner cavity of the elastic member is communicated with the airflow passage. For example, the elastic member may be a hollow elastic ball or an elastic tube closed at one end near the first side surface. In practical applications, the elastic member may be a rubber elastic member, a silicone elastic member, a plastic elastic member, or the like. Alternatively, the telescopic portion 31 may be a solid structure, and the telescopic portion is movably embedded in the mounting hole, in which case the telescopic portion 31 is understood as a movable member that can extend or retract under the driving of the driving air flow, such as a movable protrusion or a movable plug.

In an embodiment of the present application, the electronic device may further include a flexible screen; the flexible screen is disposed on the first and

second device bodies

10 and 20. In practical applications, the flexible screen may be connected to the first apparatus body 10 and the second apparatus body 20 as a single unit, and as the electronic apparatus is switched between the unfolded state and the folded state, the flexible screen is also switched between the unfolded state and the flexible bending state. In this application embodiment, in the instant that speaker 40 lets in the default current, under the effect of the elasticity of the extension of pars contractilis 31 and flexible screen's rebound resilience, need not artificial intervention, electronic equipment just can be automatic, quick withdraw from fold condition, and the user uses and experiences higher. It should be noted that the screen of the electronic device may also be a lower-cost hard screen (LCD screen or OLED screen), and this embodiment of the present application is not particularly limited, and in the embodiment of the present application, a flexible screen is taken as an example for illustrative purposes.

In the embodiment of the present application, the folded state of the electronic device may include a folded state (in which the flexible screens are hidden, this state may be referred to as a forward folded state) in which the flexible screens of the first device body 10 and the second device body 20 are opposite to each other, and a folded state (in which the flexible screens are exposed, this folded state may be referred to as a reverse folded state) in which the flexible screens of the first device body 10 and the second device body 20 are opposite to each other. When the electronic equipment is in a forward folding state, the first side face is a side face of the target equipment main body provided with the flexible screen; when the electronic device is in the unfolded state, the first side face is a side face of the target device body opposite to the flexible screen.

It should be noted that the flexible screen may also include a first flexible screen and a second flexible screen, where the first flexible screen is disposed on the first device main body 10, and the second flexible screen is disposed on the second device main body 20, when the electronic device is in a folded state, the first flexible screen and the second flexible screen are respectively in a mutually parallel folded state along with their corresponding device main bodies, and a user may respectively trigger the first flexible screen or the second flexible screen separately to trigger different functions of the electronic device; when electronic equipment was in the expansion state, first flexible screen and the concatenation of second flexible screen were a holistic display screen, and display area is bigger, and then effectively promotes the user and uses experience.

In some embodiments of the present application, the mounting hole may penetrate the target apparatus body in a first direction; the first direction is a stacking direction of the first apparatus body 10 and the second apparatus body 20 in the folded state, or the first direction may be understood as a thickness direction of the electronic apparatus; under the driving of the driving air flow, the telescopic part 31 extends out of the mounting hole from at least one end of the mounting hole. In the embodiment of the present application, the installation hole can be used for accommodating the telescopic part 31 and guiding the telescopic part 31 when the telescopic part is extended. When the electronic device is in the folded state, the expansion part 31 extends out of the mounting hole and interferes with another device body except the target device body, and when the extension force of the expansion part 31 is greater than the suction force of the electronic device in the folded state, the electronic device exits the folded state under the action of the expansion part 31.

In the embodiment of the application, the mounting holes can be replaced by mounting grooves and the like, and specific technical personnel in the field can be arranged according to actual conditions.

In the embodiment of the present application, the telescopic portion 31 is disposed in the mounting hole, so that the electronic device can be rapidly withdrawn from any one of the two folding states (forward folding and reverse folding). For example, when the electronic device has the above two folding states, the telescopic part 31 can extend out of the mounting hole from two ends of the mounting hole under the action of the driving airflow, so that the telescopic part 31 can make the electronic device quickly exit the folding state no matter the electronic device is in the forward folding state or the backward folding state.

In the embodiment of the present application, the number of the telescopic parts 31 may be one, or may be at least two, and at least two telescopic parts 31 are provided at intervals along the side edge of the target apparatus main body. In the embodiment of the present application, the at least two telescopic parts 31 are disposed on the same target device main body, so that the layout of the telescopic parts 31 is simpler, and the at least two telescopic parts 31 can make the electronic device exit from the folded state more stably and quickly. For example, when the electronic device is in the folded state under the action of the magnetic attraction force of the magnetic member 50, the number of the telescopic parts 31 may be two, and the two telescopic parts 31 are symmetrically disposed on two sides of the magnetic member 50, so that the electronic device can exit from the folded state quickly and stably under the action of the extension forces of the two telescopic parts 31. Alternatively, in the case where the number of the expansion and contraction parts 31 is plural, the plural expansion and contraction parts 31 may be provided uniformly at the circumferential side edge of the electronic apparatus.

In other embodiments of the present application, under the condition that the number of the telescopic portions 31 is at least two, at least one telescopic portion 31 is disposed on the first device body 10, and at least one telescopic portion 31 is disposed on the second device body 20, so that the telescopic portions 31 on the first device body 10 and the telescopic portions 31 on the second device body 20 can make the stress of the electronic device when the electronic device exits the folded state more uniform, and the stability of the electronic device exiting the folded state can be effectively improved.

In the embodiment of the present application, when the first device body 10 and the second device body 20 are both provided with the telescopic parts 31, the telescopic part 31 on the first device body 10 and the telescopic part 31 on the second device body 20 may be disposed oppositely or in a staggered manner, so that the telescopic parts 31 on the two device bodies may be matched with each other (it should be noted that, in the embodiment of the present application, the telescopic part 31 on one of the device bodies extends alone to enable the electronic device to exit from the folded state), thereby improving the reliability of the electronic device exiting from the folded state; alternatively, the telescopic portion 31 of the first device body 10 and the telescopic portion 31 of the second device body 20 may be disposed in a staggered manner, so that the electronic device is stressed more uniformly when exiting from the folded state.

In the embodiment of the present application, the airflow channel from the first sound cavity 42 to the pneumatic telescopic mechanism 30 may be formed by providing gaps or holes between components inside the electronic device, so as to reduce the number of components inside the electronic device and reduce the cost of the airflow channel. In the embodiment of the present application, the pneumatic telescoping mechanism 30 may further include a flow guide tube 32 connected to the telescoping portion 31; a flow guide channel connected with the first sound cavity 42 is arranged on the target equipment main body; the draft tube 32 is disposed within the draft passage, and the draft tube 32 forms at least a portion of the airflow passage. For example, the duct 32 may have a hollow structure, one end of the duct 32 is communicated with the first sound cavity 42, and the other end of the duct 32 is communicated with the telescopic portion 31 to form an airflow channel, so that the airflow channel is simpler to set, the layout difficulty inside the electronic device is further effectively reduced, and the cost of the electronic device is reduced. Or, the flow guide pipe 32 forms a part of the air flow channel, and the other part of the air flow channel is enclosed by a frame body or other structural members on the electronic device, so that the length of the flow guide pipe 32 can be effectively reduced, and the layout difficulty and the cost of the electronic device are further reduced.

In the embodiment of the present application, the flow guiding tube 32 mainly functions as an airflow flowing channel, and guides the driving airflow generated by the vibration of the diaphragm 41 to the telescopic portion 31 so as to drive the telescopic portion 31 to stretch and contract. Specifically, the flow guide tube 32 may be a flexible rubber tube, a hard plastic tube, a metal tube, or the like.

In the embodiment of the present application, the pneumatic telescoping mechanism 30 and the first sound cavity 42 are disposed on both the first device main body 10 and the second device main body 20, and the pneumatic telescoping mechanism 30 on the same target device main body is communicated with the first sound cavity 42, so that the arrangement of the air flow passage between the pneumatic telescoping mechanism 30 and the first sound cavity 42 can be made simpler.

In practical applications, the foldable electronic device may be provided with speakers 40 on both the first device body 10 and the second device body 20 to meet the use requirements of different scenes of the user. For example, when the user uses the first device main body 10 to work and the second device main body 20 is in a sleep state, the speaker 40 of the first device main body 10 can be used to work, which is more beneficial to energy saving and can effectively improve the cruising ability of the electronic device; alternatively, when the first apparatus body 10 and the second apparatus body 20 are used simultaneously, the speakers 40 on both apparatus bodies may be used simultaneously to form a better surround sound effect. In the case where the number of the speakers 40 is two and the speakers are respectively provided on the first apparatus main body 10 and the second apparatus main body 20, the number of the pneumatic telescoping mechanism 30 and the number of the speakers 40 may both be two; the first device main body 10 and the second device main body 20 are both provided with the pneumatic telescoping mechanism 30 and the speaker 40, and the pneumatic telescoping mechanism 30 on the same target device main body is communicated with the first sound cavity 42 of the speaker 40, so that the electronic device can exit from the folded state through vibration of the vibrating diaphragm 41 of the speaker 40 in different application scenes. For example, when the electronic device is in the folded state and the first device body 10 is in the working state, the driving airflow may be formed by controlling the vibration of the diaphragm 41 of the speaker 40 on the first device body 10, so as to extend the pneumatic telescopic mechanism 30, and the electronic device exits the folded state. When the electronic device is in the folded state and the second device main body 20 is in the working state, the vibrating diaphragm 41 of the speaker 40 on the second device main body 20 is controlled to vibrate to form a driving airflow, so that the pneumatic telescopic mechanism 30 is extended, and the electronic device exits the folded state.

In practical applications, the first device body 10 and the second device body 20 are both provided with the speaker 40 and the pneumatic telescopic mechanism 30, and under the condition that the speaker 40 and the pneumatic telescopic mechanism 30 correspond to each other one by one, the speaker 40 and the pneumatic telescopic mechanism 30 on the two devices can also be backed up with each other, so as to improve the reliability of the electronic device.

In other embodiments of the present application, in the case that the speakers 40 are disposed on both the first device body 10 and the second device body 20, the first sound cavities 42 of both speakers 40 may be connected to the same pneumatic telescoping mechanism 30, so that both speakers 40 may provide driving air flow for the pneumatic telescoping mechanism 30, both speakers 40 may back up each other, or both speakers 40 may provide driving air flow for the pneumatic telescoping mechanism 30 when the electronic device exits the folded state.

It should be noted that, in the embodiment of the present application, when the electronic device exits the folded state, the power key or the volume key of the electronic device may be used as the trigger key, so as to reduce the number of keys of the electronic device and improve the reuse rate of the power key or the volume key.

The electronic device is briefly described below with reference to fig. 3 and 4.

As shown in fig. 3, when the electronic device is in the folded state, the magnetic poles of the magnetic member 50 of the first device body 10 and the magnetic poles of the magnetic member 50 of the second device body 20 are opposite magnetic poles, and the electronic device can be attracted by the magnetic force between the two magnetic members 50, so that the electronic device is in the stable folded state. When the user need open the screen and make electronic equipment withdraw from fold condition, the accessible presses volume key or power key, make speaker 40 let in heavy current in the twinkling of an eye, the big amplitude motion is upwards made to speaker 40's vibrating diaphragm 41, make the interior gas compression of airflow channel, produce drive airflow, drive airflow flows to pars contractilis 31 along airflow channel, and then drive pars contractilis 31 stretches out outside the mounting hole (as shown in figure 4), magnetic attraction between magnetic part 50 is overcome to pars contractilis 31, the clearance increase between first equipment main part 10 and the second equipment main part 20, electronic equipment withdraws from fold condition. When it is detected that the electronic device is bounced off by a certain angle, that is, the gap between the first device body 10 and the second device body 20 is increased to a point where the magnetic attraction between the magnetic members 50 is not enough to pull the electronic device to the folded state again, the electronic device is further unfolded to the state shown in fig. 1 by combining with the action of human hands. In the embodiment of the application, the vibrating diaphragm 41 of the loudspeaker 40 vibrates to enable the electronic device to exit from the folded state, so that the operation is simpler and more convenient.
