The first closure member 400 is capable of closing off the first sound conduction channel 110 when the first acoustic device 200 is not required to operate. In an alternative scheme, the first blocking piece 400 may be an elastic blocking piece, and when the elastic blocking piece blocks the first sound guide channel 110, the outer surface of the elastic blocking piece and the inner surface of the first sound guide channel 110 are elastically attached by the elastic force generated by the elastic blocking piece, so that the blocking effect of the first blocking piece 400 on the first sound guide channel 110 is good.

The driving device 300 is disposed in the housing 100 and is in driving connection with the first blocking member 400, and the driving device 300 can drive the first blocking member 400 to move between the first position and the second position. Specifically, the driving device 300 may be various, such as a driving motor, a hydraulic telescopic mechanism, a pneumatic telescopic mechanism, or the like, and the embodiment of the present invention is not limited to the kind of the driving device 300.

With the first blocking piece 400 in the first position, the first blocking piece 400 is at least partially located within the first sound-guiding channel 110 to block the first sound-guiding channel 110; with the first blocking element 400 in the second position, the first blocking element 400 is located outside the first sound-guiding channel 110, so as to avoid the first sound-guiding channel 110.

In the electronic device disclosed by the invention, the driving device 300 can drive the first blocking piece 400 to move, so that the first blocking piece 400 can block or avoid the first sound guide channel 110, when the first acoustic device 200 needs to be operated, the driving device 300 drives the first blocking piece 400 to avoid the first sound guide channel 110, thereby ensuring that the acoustic signal is able to pass between the external environment and the first acoustic device 200 through the first sound guiding channel 110 normally, when the first acoustic device 200 does not need to be operated, the driving device 300 drives the first blocking member 400 to block the first sound guiding passage 110, so that foreign substances such as dust can be prevented from entering the first sound guiding passage 110, so that the first sound guiding channel 110 opened on the casing 100 of the electronic device has a dustproof function, further, the first sound guiding channel 110 can be effectively prevented from being blocked due to the accumulation of foreign matters such as dust, and the reliability of the electronic device is finally improved.

In general, the electronic device may have a plurality of acoustic devices, please refer to fig. 3, in a further alternative, the electronic device may further include a second acoustic device 500 and a second blocking member 600, the housing 100 may further have a second sound guiding channel 120, one end of the second sound guiding channel 120 is communicated with the outside of the housing 100, and the other end of the second sound guiding channel 120 is communicated with the second acoustic device 500, so as to ensure that the acoustic signal can be normally transmitted between the external environment and the second acoustic device 500 through the second sound guiding channel 120. The driving device 300 can also drive the second blocking piece 600 to move between a third position and a fourth position, in which case the second blocking piece 600 is located at least partially in the second sound guiding channel 120; with the second closure 600 in the fourth position, the second closure 600 is located outside the second sound-guiding channel 120. With this structure, when the second acoustic device 500 needs to operate, the driving device 300 drives the second blocking element 600 to avoid the second sound guiding channel 120, so as to ensure that the acoustic signal can be transmitted between the external environment and the second acoustic device 500 through the second sound guiding channel 120 normally. When the second acoustic device 500 does not need to work, the driving device 300 drives the second blocking piece 600 to block the second sound guiding channel 120, so that foreign matters such as dust can be prevented from entering the second sound guiding channel 120, the blockage of the second sound guiding channel 120 caused by the accumulation of the foreign matters such as dust can be effectively avoided, and the second acoustic device 500 can be better protected.

In the embodiment of the present invention, the electronic apparatus is provided with the first acoustic device 200 and the second acoustic device 500, and when the acoustic signal transmission is performed between the electronic apparatus and the external environment, the first acoustic device 200 may be normally operated, and the second acoustic device 500 may be stopped. Of course, the second acoustic device 500 may be operated normally, and the first acoustic device 200 may be stopped. In an optional scheme, when the first blocking piece 400 is located at the first position, the second blocking piece 600 may be located at the third position, and when the first blocking piece 400 is located at the second position, the second blocking piece 600 may be located at the fourth position, so that the first acoustic device 200 and the second acoustic device 500 can work simultaneously, and therefore transmission of acoustic signals between the electronic device and an external environment can be well achieved, and sensitivity of the electronic device in transmitting the acoustic signals is improved.

Of course, in another alternative, the second closure member 600 may be in the fourth position with the first closure member 400 in the first position and the second closure member 600 may be in the third position with the first closure member 400 in the second position, enabling complementary operation of the first acoustic device 200 and the second acoustic device 500.

As described above, the driving device 300 needs to drive the first and second occluding

members

400 and 600 to move simultaneously, so that the driving device 300 cannot be directly drive-connected to the first and second occluding

members

400 and 600 simultaneously due to the relatively long distance between the first and second

occluding members

400 and 600. Based on this, in an optional scheme, the electronic device may further include a transmission device 700, the driving device 300 drives the second blocking piece 600 to move between the third position and the fourth position through the transmission device 700, and the first blocking piece 400 and the second blocking piece 600 move simultaneously, so that the driving device 300 can drive the first blocking piece 400 and the second blocking piece 600 to move simultaneously, and thus the number of the driving devices 300 in the electronic device can be reduced, which can reduce the material cost of the electronic device, and can also save the installation space of a plurality of driving devices 300 in the electronic device, thereby reducing the stacking difficulty of other components in the electronic device.

Specifically, the transmission 700 may be variously classified, for example, a gear transmission, a chain transmission, or a belt transmission, and the classification of the transmission 700 is not limited in the embodiment of the present invention. In a further embodiment, the transmission device 700 may include a first link 710, a second link 720 and a third link 730, wherein one end of the first link 710 is hinged to one end of the second link 720, the other end of the second link 720 is hinged to one end of the third link 730, the second link 720 is rotatably disposed in the housing 100, a connection point between the second link 720 and the housing 100 is located between two ends of the second link 720, the other end of the first link 710 is drivingly connected to the driving device 300, and the other end of the third link 730 is connected to the second blocking element 600. The driving device 300 can drive the second plugging member 600 through the transmission device 700, and the transmission device 700 has the advantages of simple structure, convenient arrangement, reliable transmission and the like. In a specific movement process, the driving device 300 drives the first link 710 to move, so that the second link 720 rotates, thereby driving the third link 730 to move, and further driving the second plugging member 600 to move.

The second link 720 can be rotatably disposed relative to the housing 100 in various ways, for example, a connecting cavity is formed on the housing 100, and a limiting ball is connected to the second link 720, is disposed in the connecting cavity, and is rotatably matched with the connecting cavity; or the transmission 700 further includes a rotating shaft 740, and the second link 720 is rotatably disposed at the housing 100 through the rotating shaft 740. Both of the above manners may allow the second link 720 to be rotatably disposed on the housing 100. In the second arrangement, compared to the first arrangement, the rotation shaft 740 is conveniently arranged, so that the second link 720 can be conveniently and rotatably arranged on the housing 100. Meanwhile, the second connecting rod 720 has less rotational freedom through the rotating shaft 740, so that the movement of the transmission device 700 can be controlled more accurately, and the second blocking piece 600 can avoid or block the second sound guide channel 120 more accurately. Specifically, the embodiment of the present invention does not limit the manner in which the second link 720 is rotatably disposed with respect to the housing 100.

In the embodiment of the present invention, there are various types of the first acoustic device 200 and the second acoustic device 500, and in an alternative, the second acoustic device 500 is a microphone or a receiver; and/or the first acoustic device 200 is a microphone or a receiver. Specifically, the first acoustic device 200 and the second acoustic device 500 may be a microphone at the same time, and may also be a receiver at the same time; or while the first acoustic device 200 is a microphone, the second acoustic device 500 may be a receiver, or while the first acoustic device 200 is a receiver, the second acoustic device 500 may be a microphone, which is not limited in the embodiments of the present invention.

The first blocking piece 400 blocks the first sound guiding channel 110 by being at least partially located in the first sound guiding channel 110, and the position of the first blocking piece 400 in the first sound guiding channel 110 greatly affects the blocking effect of the first blocking piece 400 on the first sound guiding channel 110. Therefore, in an alternative scheme, with the first blocking piece 400 located at the first position, the second end surface of the first blocking piece 400 facing the outside of the housing 100 may be aligned with the outer surface of the housing 100, and this scheme can enable the port of the first sound guide channel 110 to be blocked by the first blocking piece 400 as much as possible, so that the first blocking piece 400 can better block the first sound guide channel 110, thereby improving the blocking effect.

Likewise, in order to enable the second blocking element 600 to better block the second sound guiding channel 120, in an alternative, with the second blocking element 600 located in the third position, the first end surface of the second blocking element 600 facing the outside of the housing 100 may be aligned with the outer surface of the housing 100, so that the port of the second sound guiding channel 120 is blocked by the second blocking element 600 as much as possible, thereby improving the blocking effect of the second blocking element 600 on the second sound guiding channel 120.

As mentioned above, the driving device 300 may drive the first blocking member 400 to move between the first position and the second position, in particular, the first blocking member 400 may be rotationally moved between the first position and the second position, in an alternative, the first blocking member 400 may be movably disposed within the housing 100, such that the driving device 300 may drive the first blocking member 400 to move between the first position and the second position. This way, the first blocking element 400 is easy to control, so that the first blocking element 400 can have a faster response and a higher blocking accuracy.

Of course, in order to enable the second blocking piece 600 to have the technical effects described above as well, optionally, the second blocking piece 600 is also movably arranged in the housing 100.

In the embodiment of the present invention, when the first blocking member 400 moves between the first position and the second position, a situation of jamming or unstable movement may occur, which may cause the first blocking member 400 or other parts of the electronic device to be damaged because the driving device 300 and the first blocking member 400 may be rigidly connected. Based on this, in an alternative scheme, the driving device 300 may include a moving portion 310 and an elastic member 320, the moving portion 310 is connected to the first blocking member 400 through the elastic member 320, the elastic member 320 extends along the moving direction of the first blocking member 400, and the moving portion 310 may drive the first blocking member 400 to move between the first position and the second position. The elastic member 320 may play a role of buffering when the first blocking member 400 is jammed or moves unstably, and prevent the first blocking member 400 or other parts of the electronic device from being damaged by a large force, thereby improving reliability of the electronic device. The elastic member 320 may be a spring, and the driving device 300 may further include a bracket 350, and the elastic member 320 may be disposed on the bracket 350, and the bracket 350 may be directly connected to the first blocking member 400.

Generally, there are various ways in which the moving part 310 is driven, and in an alternative, the driving device 300 may further include a driving source 330 and a lead screw 340, the lead screw 340 is in threaded fit with the moving part 310, and the driving source 330 is in driving connection with the moving part 310 through the lead screw 340, and this driving connection way has a simple structure, is easy to set, and has stable and reliable transmission and high precision.

In general, other devices to be driven may be disposed in the electronic device, and in a further embodiment, the electronic device may further include a pop-up module, the driving device 300 is drivingly connected to the pop-up module, and the driving device 300 may drive the pop-up module to at least partially extend out of the housing 100 or retract into the housing 100, so that the driving device 300 can drive more devices, thereby reducing the number of the driving devices 300 in the electronic device.

However, the pop-up module and the first closure 400 generally work relatively independently, i.e., when the pop-up module needs to move, the first closure 400 does not need to move; alternatively, the pop-up module need not move when the first closure 400 needs to move. Therefore, in other alternatives, the driving device 300 may have a first state and a second state, in which case the driving device 300 is in the first state, the driving device 300 is in driving connection with the first closure 400, and the driving device 300 is separated from the pop-up module; in the case where the driving means 300 is in the second state, the driving means 300 is separated from the first closure 400, and the driving means 300 is drivingly connected to the pop-up module. This scheme enables the driving device 300 to separately drive either the pop-up module or the first closure 400, so that the driving device 300 can drive the pop-up module or the first closure 400 in a targeted manner, thereby reducing power consumption of the electronic device and improving user experience.

In another embodiment, the driving device 300 may further have a third state, and when the driving device 300 is in the third state, the first block piece 400 and the pop-up module are both in driving connection with the driving device 300, and the driving device 300 can drive the first block piece 400 and the pop-up module to move simultaneously.

Specifically, the driving device 300 can be switched between the first state and the second state by the magnetic attraction member. Of course, the pop-up module may be a camera module, and the like, and the embodiment of the present invention is not limited.

The electronic device disclosed in the embodiment of the present invention may be a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), an electronic game machine, or the like, and the specific type of the electronic device is not limited in the embodiment of the present invention.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present invention, and is not intended to limit the present invention.
