All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

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 not limited to the number of objects, e.g., 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.

Referring to fig. 1 to 15, an electronic device provided in an embodiment of the present application includes a telescopic device 200, where the telescopic device 200 includes a first sliding sleeve 101 and a second sliding sleeve 102, and the first sliding sleeve 101 is slidably inserted into the second sliding sleeve 102;

the first sliding sleeve 101 and the second sliding sleeve 102 enclose a sound cavity 105; the telescopic device 200 is switched between an extended state and a retracted state when the first sliding sleeve 101 slides in the second sliding sleeve 102;

with the telescopic device 200 in the extended state, the sound cavity 105 has a first volume;

with the telescopic device 200 in the retracted state, the acoustic cavity 105 has a second volume, the first volume being greater than the second volume.

The above-mentioned telescopic device 200 may be a telescopic device 200 for controlling a device in an electronic apparatus to be telescopic in the electronic apparatus, for example, the telescopic device 200 may be a telescopic device 200 for adjusting a display area of a display screen of the electronic apparatus, or when the electronic apparatus is a slide type electronic apparatus, the telescopic device 200 may be a device for controlling a display screen of the electronic apparatus to slide, and in addition, the telescopic device 200 may be a control device for controlling a device in the electronic apparatus to be telescopic out of the electronic apparatus or retracted into the electronic apparatus, where a specific function of the telescopic device 200 in the electronic apparatus is not limited.

Referring to fig. 6 and fig. 10, in one embodiment of the present application, a first accommodating cavity is formed in the first sliding sleeve 101, and one end of the first sliding sleeve 101 is open, and the other end is closed; correspondingly, a second accommodating cavity is formed in the second sliding sleeve 102, and one end of the second sliding sleeve 102 is opened, and the other end is closed. The open end of the first sliding sleeve 101 is opposite to the open end of the second sliding sleeve 102, and the open end of the first sliding sleeve 101 is inserted into the second sliding sleeve 102 through the open end of the second sliding sleeve 102, so as to realize sliding connection between the first sliding sleeve 101 and the second sliding sleeve 102.

In the process that the first sliding sleeve 101 slides towards the side of the second sliding sleeve 102, the overlapping portion between the first sliding sleeve 101 and the second sliding sleeve 102 is increased, so that the volume of the sound cavity 105 formed by enclosing between the first sliding sleeve 101 and the second sliding sleeve 102 is gradually reduced. When the first sliding sleeve 101 is completely accommodated in the second sliding sleeve 102, that is, when the telescopic device 200 is in the retracted state, the sound cavity 105 has a second volume, and at this time, the second volume may refer to the volume of the second accommodating cavity.

Accordingly, in the process that the first sliding sleeve 101 slides away from the second sliding sleeve 102, the overlapping portion between the first sliding sleeve 101 and the second sliding sleeve 102 is continuously reduced, so that the volume of the sound cavity 105 formed by enclosing between the first sliding sleeve 101 and the second sliding sleeve 102 is gradually increased. When the telescopic device 200 is in the extended state, the sound cavity 105 has a first volume, and the first volume may be a union of the volume of the first receiving cavity and the volume of the second receiving cavity.

It may be appreciated that, in implementation, an opening for connecting the acoustic device with the rear cavity may be formed in the first sliding sleeve 101 and/or the second sliding sleeve 102, so that the acoustic cavity 105 may form the rear cavity of the acoustic device, thereby effectively increasing the volume of the rear cavity of the acoustic device, and further improving the audio output effect of the acoustic device. The acoustic device may be a receiver 221, a microphone, a speaker 215, etc.

In this embodiment, by forming the sound cavity 105 in the telescopic device 200 of the electronic apparatus and communicating the sound cavity 105 with the rear cavity of the acoustic device, the volume of the rear cavity of the acoustic device can be effectively increased, and thus the audio output effect of the acoustic device can be improved. Meanwhile, since the volume of the sound cavity 105 may be changed along with the expansion and contraction of the expansion and contraction device 200, the volume of the sound cavity 105 may be adjusted according to the type of the audio output by the acoustic device, so that the effect of the audio output by the acoustic device may be further improved.

Optionally, the electronic device has a first display side 201, the telescopic device 200 includes a first bracket 205 and a second bracket 206, and the first bracket 205 and the second bracket 206 are stacked;

the first sliding sleeve 101 is formed on the first support 205, the second sliding sleeve 102 is formed on the second support 206, the first support 205 is slidably connected with the second support 206 through the first sliding sleeve 101, and the first support 205 can be switched between the extended state and the retracted state relative to the second support 206 so as to adjust the display area of the first display side 201;

the first display side 201 has a first display area with the telescopic device 200 in the extended state;

in the case where the telescopic device 200 is in the retracted state, the first display side 201 has a second display area, and the first display area is larger than the second display area.

Referring to fig. 2 to 3, the telescopic device 200 operates on the following principle that the display area of the first display side 201 is adjusted: the display area of the first display side 201 is continuously changed during the telescopic movement of the telescopic device 200, wherein the display area of the first display side 201 is increased when the telescopic device 200 is extended, and the display area of the first display side 201 is maximized when the telescopic device 200 is located at the extended position shown in fig. 3. Accordingly, the display area of the first display side 201 is reduced when the telescopic device 200 is retracted, and the display area of the first display side 201 is minimized when the telescopic device 200 is in the retracted position shown in fig. 2.

The first support 205 may be slidably connected to the second support 206, where the position of the first support 205 is offset relative to the position of the second support 206 when the telescopic device 200 is in the extended state, and the first support 205 overlaps with the second support 206 when the telescopic device 200 is in the retracted state, so as to implement the telescopic operation of the telescopic device 200.

Referring to fig. 6 and 10, the first sliding sleeve 101 may be fixedly connected to the first bracket 205, or may be integrally formed with the first bracket 205. In this embodiment, the first sliding sleeve 101 is fixedly connected to the first support 205, and an open end of the first sliding sleeve 101 faces an open end of the second sliding sleeve 102 on the second support 206. Accordingly, the second sliding sleeve 102 may be fixedly connected to the second bracket 206, or may be integrally formed with the second bracket 206. In this embodiment, the second sliding sleeve 102 is integrally formed with the second bracket 206, and the open end of the second sliding sleeve 102 faces the open end of the first sliding sleeve 101 on the first bracket 205. And the first sliding sleeve 101 is inserted into the second sliding sleeve 102 through the opening end of the second sliding sleeve 102. A sealing member for sealing a gap between the first sliding sleeve 101 and the second sliding sleeve 102 may be disposed between an outer wall of the first sliding sleeve 101 and an inner wall of the second sliding sleeve 102, so as to ensure tightness of the formed sound cavity 105.

Optionally, a first through hole 103 is formed in a side wall of the first sliding sleeve 101, and a second through hole 104 is formed in a side wall of the second sliding sleeve 102;

in the case that the telescopic device 200 is in the extended state, the second through hole 104 forms an inlet of the sound cavity 105, and the second sliding sleeve 102 shields the first through hole 103 to close the first through hole 103;

with the telescopic device 200 in the retracted state, the first through hole 103 is opposite to the second through hole 104, and the first through hole 103 and the second through hole 104 together form the inlet of the sound cavity 105.

Referring to fig. 6, when the telescopic device 200 is in the extended state, the first through hole 103 and the second through hole 104 are staggered relatively, and the first through hole 103 is blocked by the inner wall of the second sliding sleeve 102, so as to close the first through hole 103, and at this time, the rear cavity of the acoustic device may be communicated with the sound cavity 105 through the first through hole 103. Accordingly, referring to fig. 7, when the telescopic device 200 is in the retracted state, the first through hole 103 is opposite to the second through hole 104, and at this time, the rear cavity of the acoustic device is communicated with the sound cavity 105 through the second through hole 104 and the first through hole 103 in sequence.

When the positions of the first through hole 103 and the second through hole 104 are offset, that is, when there is no intersection between the first through hole 103 and the second through hole 104, the first through hole 103 and the second through hole 104 cannot form different inlets of the acoustic cavity 105, respectively, because if the first through hole 103 and the second through hole 104 form the inlets of the acoustic cavity 105, respectively, the audio signals entering the acoustic cavity 105 from the first through hole 103 and the second through hole 104 cancel each other due to opposite phases, thereby reducing the audio output effect of the acoustic device. Therefore, during the process of extending the first sliding sleeve 101 relative to the second sliding sleeve 102, the stroke of the first sliding sleeve 101 is the distance between the first through hole 103 and the closed end of the first sliding sleeve 101, and the first through hole 103 cannot be exposed out of the second sliding sleeve 102. Wherein the closed end of the first sliding sleeve 101 is an end opposite to the open end of the first sliding sleeve 101.

Optionally, the electronic device further comprises a first acoustic device, the first acoustic device is connected to the second support 206, and a rear cavity of the first acoustic device is communicated with the sound cavity 105 through an inlet of the sound cavity 105.

In this embodiment, the first acoustic device is connected to the second support 206, and the rear cavity of the first acoustic device is communicated with the sound cavity 105 through the inlet of the sound cavity 105, so that the rear cavity space of the first acoustic device can be increased, and the output effect of the sound cavity 105 of the first acoustic device is improved.

Optionally, the telescopic device 200 includes a telescopic end and a fixed end that are disposed opposite to each other, the telescopic end is formed on the first bracket 205, and the fixed end is formed on the second bracket 206;

the first through hole 103 is located on a side wall of one end, far away from the telescopic end, of the first sliding sleeve 101, and the second through hole 104 is located on a side wall of one end, close to the fixed end, of the second sliding sleeve 102.

Specifically, referring to fig. 10, the first through hole 103 is located on a side wall of the first sliding sleeve 101 at an end far away from the telescopic end, that is, the first through hole 103 is near to the open end of the first sliding sleeve 101; the second through hole 104 is located on a side wall of the second sliding sleeve 102 near the fixed end, that is, the second opening is far away from the open end of the second sliding sleeve 102, and the first opening and the second opening are located on the same side.

In this embodiment, the first through hole 103 is disposed on a side wall of the first sliding sleeve 101, which is far away from the end of the telescopic end, and the second through hole 104 is disposed on a side wall of the second sliding sleeve 102, which is close to the end of the fixed end, so that the stroke of the first sliding sleeve 101 can be increased, and the adjustment range of the volume of the sound cavity 105 can be increased.

Optionally, the electronic device further has a second display side 202 opposite to the first display side 201, the electronic device further comprising a drive assembly 300 and a flexible screen 400;

the flexible screen 400 is laid on the surface of the telescopic device 200, the first end 401 of the flexible screen 400 is connected with the first bracket 205, and the second end 402 of the flexible screen 400 is connected with the driving assembly 300;

the driving assembly 300 is used for driving the flexible screen 400 to move so as to drive the first bracket 205 to switch between the extending state and the retracting state;

with the first stand 205 in the extended state, the first display side 201 includes a first region 203 and a second region 204, and the flexible screen 400 covers the first region 203 and the second region 204;

With the first bracket 205 in the retracted state, the flexible screen 400 covers the first region 203 and the second display side 202.

Referring to fig. 3, fig. 3 is a schematic structural diagram of the electronic device when the telescopic device 200 is in the extended state, where the display area of the first display side 201 is the largest, and the first display side 201 includes a first area 203 and a second area 204. During the gradual retraction of the telescopic device 200 from the extended state, the display area of the second area 204 gradually decreases until the telescopic device 200 is fully retracted to the retracted state as depicted in fig. 2, at which time the first display side 201 comprises only the first area 203.

It will be appreciated that the telescopic device 200 may be moved to any telescopic position between the telescopic state and the retracted state, in addition to the extended state and the retracted state, so that the adjustment of the display area of the first display side 201 may be achieved by controlling the telescopic movement of the telescopic device 200.

In addition, referring to fig. 2, in the case where the folder 200 is in the retracted state, since the flexible screen 400 covers both the first display side 201 and the second display side 202 of the folder 200, the electronic apparatus may also form a double-sided screen in this state. Thereby further improving the adjustability of the form of the flexible screen 400 and alleviating the problem that the existing display screen is not adjustable in form.

Referring to fig. 3, in the process of adjusting the shape of the flexible screen 400, the driving device drives the second end 402 of the flexible screen 400 to move in the second display side 202 along the side facing the first end 401 of the flexible screen 400, and in this process, the first end 401 of the flexible screen 400 drives the telescopic device 200 to retract, that is, drives the first support 205 of the telescopic device 200 to move toward the second support 206, and the display area of the first display side 201 gradually decreases, and the display area of the second display side 202 gradually increases until moving to the retracted state as described in fig. 2.

In this embodiment, the flexible screen 400 is laid on the surface of the telescopic device 200, so that the flexible screen 400 and the telescopic device 200 synchronously move under the driving of the driving device, so as to change the shape of the flexible screen 400, wherein the flexible screen 400 can form a telescopic screen in the telescopic process of the telescopic device 200, and the flexible screen 400 can form a double-sided screen when the telescopic device 200 is in a retracted state, thereby effectively improving the shape adjustability of the flexible screen 400 and alleviating the problem that the existing display screen is not adjustable in shape.

A first end 401 of the flexible screen 400 is connected with the telescopic end, a second end 402 of the flexible screen 400 sequentially bypasses the first display side 201 and the fixed end and extends to the second display side 202, and the driving assembly 300 is used for driving the second end to move in the second display side 202;

the second end 402 of the flexible screen 400 is adjacent to the fixed end with the first bracket 205 in the extended state and the second end 402 of the flexible screen 400 is adjacent to the telescoping end with the first bracket 205 in the retracted state.

Wherein the fixed end may be located on the second bracket 206, and the telescopic end may be located on the first bracket 205.

The telescopic end may refer to an end that reciprocates during the telescopic operation of the telescopic device 200, and the fixed end may refer to an end that maintains a constant position during the telescopic operation of the telescopic device 200. It will be appreciated that the distance between the telescopic end and the fixed end is continuously changed during the telescopic movement of the telescopic device 200, the distance between the telescopic end and the fixed end is increased during the extension of the telescopic device 200, and the distance between the telescopic end and the fixed end is gradually decreased during the retraction of the telescopic device 200.

In this embodiment, the first end 401 of the flexible screen 400 is connected to the telescopic end, and the second end 402 of the flexible screen 400 sequentially bypasses the first display side 201 and the fixed end and extends to the second display side 202, so that, as shown in fig. 3, when the driving device drives the second end 402 of the flexible screen 400 to move towards the telescopic end, the first end 401 of the flexible screen 400 can pull the telescopic end to retract. Accordingly, as shown in fig. 2, when the telescopic device 200 drives the second end 402 of the flexible screen 400 to move towards the fixed end, the second end 402 of the flexible screen 400 may push the telescopic end to extend. Thus, the telescopic movement of the telescopic device 200 can be controlled.

Optionally, the driving assembly 300 includes a driving module and a conveyor belt 301, and a length direction of the conveyor belt 301 is the same as a telescoping direction of the telescoping device 200;

the driving module is connected with the conveyor belt 301 to drive the conveyor belt 301 to rotate forward or backward;

the second end 402 of the flexible screen 400 is connected to the conveyor belt 301, and the second end is driven by the conveyor belt 301 to reciprocate in the second display side 202 during the forward rotation or the reverse rotation of the conveyor belt 301.

Referring to fig. 2 to 3, the conveyor belt 301 may be mounted on the second bracket 206, for example, the conveyor belt 301 may be mounted on a side portion of the second bracket 206, an upper surface of the conveyor belt may be flush with the first display side 201, and a lower surface of the conveyor belt may be flush with the second display side 202.

The second end 402 of the flexible screen 400 may be adhered to the conveyor belt 301, and the flexible screen 400 may be slid with respect to the second support 206, i.e., the position between the flexible screen 400 and the second support 206 may be relatively changed. Thus, during the forward and reverse rotation of the conveyor belt 301, the conveyor belt 301 may drive the second end 402 of the flexible screen 400 to reciprocate within the second display side 202. Specifically, referring to fig. 2, when the conveyor belt 301 rotates clockwise, the second end 402 of the flexible screen 400 will move leftwards, i.e. to the fixed end, along with the conveyor belt 301 due to the fixed connection between the conveyor belt and the second end 402 of the flexible screen 400, and at this time, the flexible screen 400 slides integrally to the second display side 202 of the telescopic device 200, and the first end 401 of the flexible screen 400 pushes the first bracket 205 to extend, so that the area of the flexible screen 400 located in the first display side 201 is increased, i.e. the display area of the first display side 201 is increased. Accordingly, when the driving belt rotates counterclockwise, the first end 401 of the flexible screen 400 pulls the first bracket 205 to retract, and at the same time, the flexible screen 400 slides toward the second display side 202 as a whole, the display area of the first area decreases, and the display area of the second display side 202 increases.

Optionally, the driving module includes a driving member 302, a driving shaft 303, a driven shaft 304, a driving wheel 305, and a driven wheel 306, where the driving member 302 is connected to the driving shaft 303 to drive the driving shaft 303 to rotate;

the driving wheel 305 is sleeved on the driving wheel 303, the driven wheel 306 is sleeved on the driven wheel 304, and the conveying belt 301 is arranged on the driving wheel 305 and the driving wheel;

during the rotation of the driving shaft 303, the driving shaft 303 drives the conveyor belt 301 to rotate in a forward or reverse direction, and the driven wheel 306 follows the conveyor belt 301 to rotate.

Referring to fig. 2 to 3, the driving shaft 303 and the driven shaft 304 may be disposed at both ends of the second bracket 206, respectively, and the driving shaft 303 and the driven shaft 304 may be disposed perpendicular to the telescopic direction of the telescopic device 200, respectively. Thus, when the driving shaft 303 rotates, any point on the conveyor 301 reciprocates along the telescopic direction of the telescopic device 200, and since the second end 402 of the flexible screen 400 is connected to a certain position on the conveyor 301, the conveyor 301 will drive the second end 402 of the flexible screen 400 to reciprocate along the telescopic direction of the telescopic device 200, so as to push the first bracket 205 to perform telescopic motion.

Referring to fig. 1, in one embodiment of the present application, the number of driving shafts 303 is 2, two ends of the 2 driving shafts 303 respectively extend out of the second bracket 206 from two sides of the second bracket 206, and two driving shafts 303 are respectively provided with one driving wheel 305. The number of driven shafts 304 may be 1, and two ends of the driven shafts 304 extend from two sides of the second support 206, where, of course, the number of driven shafts 304 may be 2, two ends of 2 driven shafts 304 extend from two sides of the second support 206 outside the second support 206, and driven shafts 304 extending from two sides of the second support 206 are respectively sleeved with one driven wheel 306. Correspondingly, the number of the driving belts is 2, and 2 driving belts 301 are respectively arranged on the driving wheel 305 and the driven wheel 306 at two sides of the second bracket 206. In a specific implementation, two driving members 302 may be used to drive two driving shafts 303 respectively, and of course, a motor including two output shafts as shown in fig. 1 may also be used, where the motor and the two driving shafts 303 are arranged on the same line, and the two output shafts of the motor are connected to the two driving shafts 303 through a speed reducer 307 respectively, so as to drive the two driving shafts 303 to rotate synchronously.
