Background

As user demands increase, performance of electronic devices continues to optimize. Among them, the acoustic performance of electronic devices is getting better.

Obviously, this results in that the sound performance of the electronic device cannot be further improved. The acoustic performance of the electronic devices involved in the related art is still at a poor level.

It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The technical scheme disclosed by the embodiment of the application is described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, an embodiment of the present application discloses an electronic device, which includes a first housing 100, a second housing 200, and a speaker 300.

The first and second cases 100 and 200 are basic members of the electronic device, may provide a mounting basis for a part of functional devices of the electronic device, such as the speaker 300 and the PCB 600, and the speaker 300 may be electrically connected to the PCB 600.

The first housing 100 and the second housing 200 are relatively movable. The speaker 300 includes a speaker body 310 and a telescopic rear cavity 320, wherein the speaker body 310 is disposed on the first housing 100 and can move along with the first housing 100, and the telescopic rear cavity 320 is connected between the speaker body 310 and the second housing 200.

The electronic device is switchable between an expanded state and a contracted state with the relative movement of the first housing 100 and the second housing 200.

In the process of switching the electronic device to the unfolded state, the first housing 100 and the second housing 200 move in the direction away from each other, the distance between the first housing 100 and the second housing 200 increases, the internal space of the electronic device increases, a required space is provided for the unfolding of the telescopic rear cavity 320, and the speaker main body 310 connected with the first housing 100 moves synchronously with the first housing 100, so that the telescopic rear cavity 320 connected between the speaker main body 310 and the second housing 200 is stretched, and the volume of the inner cavity of the telescopic rear cavity 320 gradually increases until the volume of the inner cavity of the telescopic rear cavity 320 increases to the first volume when the electronic device is in the unfolded state.

In the process of switching the electronic device to the contracted state, the first housing 100 and the second housing 200 move in directions close to each other, the distance between the first housing 100 and the second housing 200 decreases, the volume of the internal space of the electronic device decreases, the speaker main body 310 connected with the first housing 100 moves synchronously with the first housing 100, the telescopic rear cavity 320 connected between the speaker main body 310 and the second housing 200 is compressed, and then the volume of the inner cavity of the telescopic rear cavity 320 is gradually reduced until the volume of the inner cavity of the telescopic rear cavity 320 decreases to a second volume when the electronic device is in the contracted state, and the second volume is smaller than the first volume.

In the embodiment disclosed by the application, the electronic equipment is switched between the unfolding state and the shrinking state, and the electronic equipment compresses the telescopic rear cavity 320 in the shrinking process, so that the volume of the electronic equipment is reduced to a second volume, and correspondingly, the volume of the electronic equipment is reduced, so that the space layout in the inner cavity of the equipment is more compact, and the pursuit of a user for higher integration level of the electronic equipment at present is met; the electronic device stretches the telescopic rear cavity 320 in the unfolding process, so that the volume of the telescopic rear cavity is increased to the first volume, and therefore sound played by the loudspeaker 300 has a better low-frequency effect, and further the sound played by the loudspeaker 300 is clearer and brighter. Therefore, the electronic equipment disclosed by the embodiment of the application can solve the problem that the acoustic performance of the electronic equipment related to the related technology is still in a poor level.

In a further technical solution, the electronic device disclosed in the embodiments of the present application may further include a display screen 400, where the display screen 400 may be mounted on the first housing 100 or the second housing 200. However, when the display screen 400 is mounted on the first housing 100 or the second housing 200, the display screen 400 cannot be presented on the electronic device in a larger area, so that the aesthetic appearance of the electronic device is not only affected, but also the pursuit of a large screen by a user cannot be satisfied, and finally the use experience of the user is affected, so that the electronic device with the structure has no competitiveness in like products.

In order to solve the above-described problems, in the disclosed embodiment of the present application, a first end portion of the display screen 400 may be movably coupled to the first housing 100, and a second end portion of the display screen 400 may be coupled to the second housing 200. When the electronic device is in the unfolded state, the area of the portion of the display screen 400 exposed outside the electronic device is the first area; when the electronic device is in the contracted state, the area of the portion of the display screen 400 exposed outside the electronic device is a second area, and the first area is larger than the second area. That is, the size of the portion of the display screen 400 exposed outside the electronic device may be adaptively changed according to the change in the size of the electronic device. In the process of unfolding the electronic equipment, part or all of the display screen 400 stored in the electronic equipment moves out of the electronic equipment, so that the area of the part of the display screen 400 exposed out of the electronic equipment is increased, and the use experience of a user is improved; during the shrinking process of the electronic device, a portion of the display screen 400 moves into the electronic device, so that more area of the display screen 400 is accommodated in the first housing 100 or the second housing 200, and further, the area of the portion of the display screen 400 exposed outside the electronic device is reduced.

In the above-described aspect, the display screen 400 may be housed inside the electronic device by winding or folding.

Alternatively, the display screen 400 may be a curled screen, which may be capable of being curled and bent so as to be at least partially retractable in the first housing 100. When the electronic device is in the unfolded state, the curled screen can be extended from the inside of the first housing 100 and unfolded out of the first housing 100, and at this time, the area of the curled screen exposed out of the electronic device increases. In a case where the electronic apparatus is in a contracted state, a portion of the curled screen is contracted into the first housing 100, so that an area of the curled screen exposed to the outside of the electronic apparatus is reduced. Other types of display screens 400 may also be employed for the display screen 400, as this is not limiting.

In order to enable at least part of the curled screen to be retractable into the first housing 100 and to extend out of the first housing 100, in the disclosed embodiment of the application, the first housing 100 may be provided with an opening, a rotatable shaft 700 may be disposed in the first housing 100, a first end portion of the curled screen is connected to the shaft 700, and the curled screen may be rolled in the first housing 100 through the opening or extend out of the first housing 100 through the opening.

In a specific operation, when the first and second cases 100 and 200 are moved in a direction approaching each other, at least a portion of the crimp screen is contracted into the first case 100 through the opening, and the portion of the crimp screen contracted into the first case 100 is wound around the rotation shaft 700 to reduce an area of the crimp screen protruding to the outside of the electronic device, while the rotation shaft 700 is a cylindrical member, and also to prevent the crimp screen from being bent to be damaged.

When the first and second cases 100 and 200 are moved in a direction away from each other, at least a portion of the crimp screen protrudes outside the first case 100 through the opening, and in the process, a portion of the crimp screen wound around the rotation shaft 700 protrudes outside the first case 100 through the opening and is spread out outside the first case 100.

In order to prevent the curled screen from being cracked due to excessive tension applied to the curled screen during the relative movement of the first and second housings 100 and 200, the rotating shaft 700 may rotate around its axis with respect to the first housing 100, and the curled screen may be wound around the rotating shaft 700 or released from the rotating shaft 700 during the rotation of the rotating shaft 700. The curled screen can be contracted in the first housing 100 or extended and unfolded from the inside of the first housing 100 by changing the rotation direction of the rotation shaft 700, so that the extension and contraction processes of the curled screen can be more convenient, and the curled screen can be protected from being damaged.

In the above-mentioned scheme, if the moving path is shifted during the relative movement of the first housing 100 and the second housing 200, the functional devices in the electronic apparatus may collide or squeeze each other, resulting in damage of the functional devices. In order to solve the above-mentioned problem, the first housing 100 may further include a guide portion 110, the guide portion 110 may be inserted into the second housing 200, and the guide portion 110 is slidably engaged with the second housing 200. At least a portion of the guide 110 is located outside the second housing 200 in the case where the electronic device is in the unfolded state, and the guide 110 is located inside the second housing 200 in the case where the electronic device is in the folded state.

The guide 110 restricts the movement path of the first housing 100 and the second housing 200, thereby improving the accuracy of the relative movement between the two. In addition, the guide portion 110 is inserted into the second housing 200, and the mating relationship between the first housing 100 and the second housing 200 is not required to be changed.

In the electronic device disclosed in the embodiment of the present application, there may be various sound emitting structures of the speaker 300, for example, there are assembly gaps between components of the electronic device, and the speaker 300 may implement sound through the assembly gaps. Of course, the electronic device may also be specially provided with a sound output structure to realize sound. In an alternative solution, the speaker main body 310 may be disposed in a space surrounded by the guide portion 110 of the first housing 100, the speaker main body 310 may be provided with a first sound outlet 312, the guide portion 110 may be provided with a first sound guide hole 111, the second housing 200 may be provided with a second sound guide hole 210, and the first sound outlet 312 may be communicated with the first sound guide hole 111.

When the electronic device is in the unfolded state, the first sound guiding hole 111 moves along with the guiding portion 110 to outside the second housing 200, and the first sound guiding hole 111 and the second sound guiding hole 210 are distributed in a staggered manner. In this case, the sound signal emitted from the speaker 300 is sequentially transmitted to the outside of the electronic device through the first sound outlet 312 and the first sound guiding hole 111, the second sound guiding hole 210 is blocked, and the sound signal cannot be transmitted in the second sound guiding hole 210.

When the electronic device is in the contracted state, the first sound guiding hole 111 moves into the second housing 200 along with the guiding portion 110, and the first sound guiding hole 111 is disposed opposite to and in communication with the second sound guiding hole 210, and the first sound outlet hole 312 and the second sound guiding hole 210 are in communication by the first sound guiding hole 111. In this case, the sound signal emitted from the speaker 300 is transmitted to the outside of the electronic device through the first sound outlet 312, the first sound guiding hole 111, and the second sound guiding hole 210 in sequence.

The above-mentioned sound outputting structure can better adapt to the matching change between the first housing 100 and the second housing 200 including the guiding portion 110, so as to avoid the sound outputting of the speaker 300 from being affected by the change of the relative positions between the first housing 100 and the second housing 200. Meanwhile, the sound emitting structure is beneficial to realizing the arrangement of the sound emitting structure on the side face of the electronic equipment, and is free from the influence of the display screen 400, so that a user cannot easily see the sound emitting structure on the front face of the electronic equipment, and the appearance performance of the electronic equipment is improved.

In the embodiment disclosed in the present application, the electronic device may further include a receiver 500, where the receiver 500 is disposed in a space surrounded by the guide portion 110 of the first housing 100, the receiver 500 is provided with a second sound outlet, the receiver 500 is adjacent to one end of the guide portion 110, and the speaker 300 is adjacent to the other end of the guide portion 110. The guide portion 110 is provided with a third sound guiding hole 112, and the second housing 200 is provided with a fourth sound guiding hole.

When the electronic device is in the unfolded state, the third sound guiding hole 112 moves along with the guiding portion 110 to the outside of the second housing 200, and the third sound guiding hole 112 and the fourth sound guiding hole are distributed in a staggered manner. In this case, the sound signal emitted by the receiver 500 is sequentially transmitted to the outside of the electronic device through the second sound outlet hole and the third sound guiding hole 112, the fourth sound guiding hole is blocked, and the sound signal cannot be transmitted in the fourth sound guiding hole.

When the electronic device is in the contracted state, the third sound guiding hole 112 moves into the second housing 200 along with the guiding portion 110, and the third sound guiding hole 112 is opposite to and communicates with the fourth sound guiding hole, and the second sound outlet hole and the fourth sound guiding hole are communicated by the third sound guiding hole 112. At this time, the sound signal emitted by the receiver 500 is transmitted to the outside of the electronic device through the second sound outlet, the third sound guiding hole 112 and the fourth sound guiding hole in sequence.

The above-mentioned sound outputting structure can better adapt to the matching change between the first housing 100 and the second housing 200 including the guiding portion 110, so as to avoid the sound outputting of the receiver 500 from being affected by the change of the relative positions between the first housing 100 and the second housing 200. Meanwhile, the sound emitting structure is beneficial to realizing the arrangement of the sound emitting structure on the side face of the electronic equipment, and is free from the influence of the display screen 400, so that a user cannot easily see the sound emitting structure on the front face of the electronic equipment, and the appearance performance of the electronic equipment is improved.

In the embodiment of the present application, the structure of the telescopic rear cavity 320 may be various, for example, the telescopic rear cavity 320 may be a flexible structural member, for example, the telescopic rear cavity 320 may be a flexible bag.

Of course, other structures may be adopted for the telescopic rear cavity 320, and the embodiment of the present application does not limit the specific structure of the telescopic rear cavity 320. Referring to fig. 5 and 6, the present application discloses a specific structure of the telescopic rear cavity 320. Specifically, the speaker main body 310 may be provided with the rear cavity interface 311, the telescopic rear cavity 320 may include a telescopic cylinder 321, a first plugging plate 322 and a second plugging plate 323, two opposite ports of the telescopic cylinder 321 are a first port and a second port respectively, along the telescopic direction of the telescopic cylinder 321, the first port and the second port are respectively provided at two ends of the telescopic cylinder 321, the first plugging plate 322 is plugged at the first port, the first plugging plate 322 is fixedly connected with the second housing 200, the second plugging plate 323 is plugged at a first area of the second port, and a second area of the second port is communicated with the rear cavity interface 311. The first closure plate 322 may be sealingly connected to the first port by means of adhesive or the like.

In the above-mentioned scheme, the second area of the second port is communicated with the rear cavity interface 311, so that the speaker main body 310 is communicated with the telescopic rear cavity 320, and the first area of the second port of the telescopic rear cavity 320 and the first port of the telescopic rear cavity 320 are plugged by the second plugging plate 323 and the first plugging plate 322 respectively, so that the telescopic rear cavity 320 and the equipment inner cavity of the electronic equipment are better isolated from each other, and thus leakage sound is better prevented.

In addition, when the telescopic rear cavity 320 is mounted on the second housing 200, in order to ensure good sealing performance inside the telescopic rear cavity 320, the telescopic rear cavity 320 needs to be in sealing connection with the contact position of the second housing 200, if the first plugging plate 322 is not provided, the telescopic cylinder 321 is directly mounted on the second housing 200, because the telescopic cylinder 321 needs to be fixedly connected with the second housing 200 everywhere, and the operability space of the equipment inner cavity of the electronic equipment is smaller, so that the mounting operation is difficult. In the embodiment disclosed by the application, before installation, the first plugging plate 322 can be fixedly connected with the first port in a sealing way, and then the first plugging plate 322 is fixedly connected with the second shell 200, so that the telescopic rear cavity 320 is installed in the second shell 200, and as the first plugging plate 322 has better rigidity, the first plugging plate 322 is only connected with the inner wall of the second shell 200 through a structure such as a screw, thereby greatly reducing the installation difficulty.

Similarly, the second plugging plate 323 may be sealed and fixed at the second port, and then the second plugging plate 323 is connected with the first housing 100. In this case, the sealing of the telescopic rear chamber 320 and the fitting connection with the first housing 100 are also facilitated.

In an alternative embodiment, the second plugging plate 323 may be fixedly connected to the speaker main body 310, and since the speaker main body 310 is disposed on the first housing 100, the second plugging plate 323 is indirectly disposed on the first housing 100, and further moves along with the first housing 100 under the driving of the speaker main body 310. Under such circumstances, when the speaker main body 310 moves, the second plugging plate 323 drives the telescopic cylinder 321 to move along the direction of the second port, and as the second plugging plate 323 can drive more edges of the second port to move, the second port is uniformly stressed, so that the movement direction of the telescopic cylinder 321 is prevented from being deviated due to uneven stress of the second port, and unnecessary interference can be avoided.

Alternatively, the telescopic cylinder 321 may be a bellows-shaped structural member, and of course, may be other structural members capable of changing the volume of the internal space by telescopic operation.

In an alternative solution, the bellows-like structure may include a plurality of frameworks and a flexible sleeve sleeved on the plurality of frameworks, where the plurality of frameworks are sequentially arranged at intervals in the telescopic direction of the telescopic cylinder 321. In the process of relatively moving the first housing 100 and the second housing 200, the plurality of frames are close to or far away from each other, thereby realizing the expansion and contraction of the flexible sleeve. The flexible sleeve body has good folding and deforming capacity and can deform along with the expansion applicability of the framework. Referring to fig. 4, in the case where the electronic device is in the unfolded state, along the direction in which the first housing 100 and the second housing 200 relatively move, the plurality of frames are far away from each other, so that the flexible sleeve is unfolded, and the volume of the telescopic cylinder 321 is further increased to the first volume; referring to fig. 3, in the case where the electronic device is in the contracted state, the plurality of frames are close to each other along the direction in which the first and second housings 100 and 200 are relatively moved, and the flexible sleeve is folded or contracted, so that the volume of the telescopic cylinder 321 is reduced to the second volume. In this case, the bellows-shaped structural member has a telescopic performance in the penetrating direction, and has a better strength under the support of a plurality of frameworks in the direction perpendicular to the penetrating direction, so that the telescopic cylinder 321 with the structure can not be easily shrunken to affect the cavity expansion effect of the telescopic rear cavity 320. The flexible sleeve may be a flexible film member.

In the disclosed embodiment of the present application, the relative movement of the first housing 100 and the second housing 200 may be achieved by a manual operation. For example, the two hands of the user grasp the first and second housings 100 and 200, respectively, and thus manipulate the first and second housings 100 and 200 toward or away from each other, ultimately effecting relative movement of the first and second housings 100 and 200. However, since the method is easily affected by human factors, it is not easy to precisely control the relative movement distance of the first housing 100 and the second housing 200, and when the external force is too large, the relative movement distance of the first housing 100 and the second housing 200 is easily too large, resulting in the disconnection or bending of the first housing 100 and the second housing 200.

In order to solve the above-described problems, in the disclosed embodiment of the present application, the electronic apparatus may further include a driving mechanism provided between the first housing 100 and the second housing 200, the driving mechanism driving the first housing 100 and the second housing 200 to be away from or close to each other. Alternatively, the driving mechanism may be a linear motor, an air cylinder, or a stepper motor, and when the driving mechanism is a stepper motor, the stepper motor may be connected to the first housing 100 or the second housing 200 through a transmission member such as a ball screw. The driving mechanism can enable the control of the electronic equipment to be more automatic and intelligent, and is further beneficial to improving the service performance of the electronic equipment.

As described above, the display screen 400 may be a curled screen, the curled screen needs to be retracted in the first housing 100 or extend out of the first housing 100 by means of the rotation of the rotating shaft 700, and the power device is required to provide the driving force for the rotation of the rotating shaft 700. The drive motor may be a stepper motor.

Of course, it should be noted that the curled screen can be extended or retracted by itself to drive the relative movement between the first housing 100 and the second housing 200, which requires that the curled screen has better strength, and thus better force transmission can be achieved.

In this case, it is possible to ensure that the extension distance or the contraction distance of the roll screen is equal to the distance in which the first housing 100 and the second housing 200 relatively move from time to time, preventing the relative movement distance of the first housing 100 and the second housing 200 from being greater than the extension distance of the roll screen, resulting in the roll screen being excessively stretched or bent by an external force.

The electronic device disclosed by the embodiment of the application can be a smart phone, a tablet personal computer, an electronic book reader or a wearable device. Of course, the electronic device may be another device, which is not limited in accordance with the embodiments of the present application.
