Referring to fig. 1-3 and fig. 5 together, an electronic device 200 according to an embodiment of the invention includes a housing 10, an electroacoustic element 20, a cover 30, a dust-proof member 40 and a driving part 100. The case 10 has a first through hole 10a, a cover plate 30 is provided on the front side of the case 10, the cover plate 30 is provided with a second through hole 31, and the second through hole 31 is provided substantially in alignment with the first through hole 10a and forms a sound signal transmission channel (hereinafter referred to as a sound channel) of the electroacoustic element 20.

The driving part 100 is connected to the dust-proof member 40 for driving the dust-proof member 40 to rotate between a first position, in which the dust-proof member 40 shields the second through hole 31, and a second position, in which the dust-proof member 40 opens the second through hole 31.

Referring to fig. 4, an electronic device 200 according to an embodiment of the invention is an electronic device such as a mobile phone, an intelligent wearable device, or a tablet computer. It is understood that the electronic device 200 includes, but is not limited to, examples of the present embodiment.

In the electronic device 200 according to the embodiment of the invention, the dust-proof member 40 can shield the second through hole 31 according to the requirement, thereby preventing impurities such as dust from entering the electronic device 200 from the second through hole 31, avoiding the malfunction of the electronic device 200 caused by the impurities such as dust, and prolonging the service life of the electronic device 200.

Specifically, the electroacoustic element 20 corresponds to the second through hole 31, and the second through hole 31 corresponds to the electroacoustic element 20 means that the sound emitted by the electroacoustic element 20 can be transmitted to the outside of the electronic device 200 through the second through hole 31. The second through hole 31 may be disposed opposite to the electroacoustic element 20 or may be disposed in a staggered manner with respect to the electroacoustic element 20.

The housing 10 is, for example, a front housing of the electronic device 200, the housing 10 is substantially rectangular parallelepiped, the housing 10 is a carrier of the electronic device 200, and most parts of the electronic device 200 are mounted on the housing 10. The electronic device 200 further comprises a back cover 220, the back cover 220 covering the internal parts of the electronic device 200, e.g. the back cover 220 may cover the battery (not shown), the electroacoustic element 20 etc. The rear cover 220 is made of plastic or glass, for example. It is understood that a battery is used to power the electronic device 200.

Electroacoustic element 20 is an element that can convert an electrical signal into an acoustic signal, for example electroacoustic element 20 is a speaker. In this embodiment, the electroacoustic element 20 is a receiver, and the electroacoustic element 20 is located on the top of the electronic device 200, so as to facilitate the user to answer the call.

The cover plate 30 covers the display screen 210 of the electronic device 200, so that the display screen 210 is prevented from being damaged by touching. The cover plate 30 may be made of a light-transmitting material such as glass, plastic, or the like. The second through hole 31 formed in the cover plate 30 penetrates through two opposite surfaces of the cover plate 30. The second through hole 31 has a rectangular cross section, for example.

The color of the dust-proof member 40 may be consistent with the color around the dust-proof member 40 so that the user does not easily perceive the presence of the dust-proof member 40, which may improve the appearance performance of the electronic device 200. Of course, the color of the dust-proof member 40 may be different from the color around the dust-proof member 40, for example, the color of the dust-proof member 40 is red, and the color around the dust-proof member 40 is black. This allows the dust guard 40 to play a decorative role and identifies the location of the electroacoustic element 20 for the convenience of the user to use the electroacoustic element 20.

The shielding of the second through hole 31 by the dust-proof member 40 means that the dust-proof member 40 blocks the second through hole 31 from communicating with the interior of the electronic device 200, for example, the dust-proof member 40 may be attached to the surface of the cover plate 30 so as to shield the second through hole 31. The dust-proof member 40 opening the second through hole 31 means that the dust-proof member 40 forms a certain gap with the surface of the cover plate 30, so that the second through hole 31 communicates with the inside of the electronic device 200. It can be understood that a sound channel is formed between the second through hole 31 and the electroacoustic device 20, and when the dust-proof member 40 shields the second through hole 31, the dust-proof member 40 blocks the sound channel, and the sound generated by the electroacoustic device 20 cannot be transmitted to the outside of the electronic device 200 through the second through hole 31.

Referring again to fig. 1-3, in some embodiments, the housing 10 includes a front surface 11, the cover 30 is disposed on the front surface 11, the housing 10 is formed with a relief groove 12, the relief groove 12 extends from the front surface 11 in a direction away from the dust-proof member 40, and the relief groove 12 is configured to provide a movable space for rotation of the dust-proof member 40. In this way, the escape groove 12 can avoid interference of the dust-proof member 40 with the housing 10. It will be appreciated that the size of the relief groove 12 is greater than the size of the dust guard 40 so that the relief groove 12 provides sufficient room for the dust guard 40 to move.

In some embodiments, the dust guard 40 is rotatable about the rotation shaft 41 to shield or open the second through hole 31, the rotation shaft 41 extending in the lateral direction of the housing 10. In this way, the dust-proof member 40 can rotate in the lateral direction around the housing 10. As shown in the azimuth of fig. 1, the lateral direction of the housing 10 is the left-right direction, that is, the rotation shaft 41 extends in the left-right direction. As shown in the orientation of 2, the dust guard 40 may swing in the front-rear direction. When the dust-proof member 40 swings backward, the dust-proof member 40 opens the second through hole 31; when the dust-proof member 40 swings forward, the dust-proof member 40 shields the second through hole 31.

It can be understood that the dust-proof member 40 is fixedly connected to the rotating shaft 41, and in this embodiment, the dust-proof member 40 is clamped and fixed to the rotating shaft 41. Of course, in other embodiments, the dust-proof member 40 and the rotating shaft 41 may be integrally formed or fixedly connected by welding.

In some embodiments, one end of the rotating shaft 41 is connected with the rotating arm 42, the rotating arm 42 penetrates through the housing 10, the driving component 100 includes a driving mechanism 50 and a driving device 60, the driving mechanism 50 and the driving device 60 are located on one side of the housing 10 opposite to the cover plate 30, the driving mechanism 50 is connected with the rotating arm 42, and the driving device 60 is used for driving the rotating arm 42 to swing through the driving mechanism 50 so as to enable the dust-proof piece 40 to rotate.

In this way, the structure of driving the dust-proof member 40 to rotate by the swivel arm 42 is simple. As shown in the orientation of fig. 2, when the dust-proof member 40 shields the second through hole 31, the rotary arm 42 swings downward, and at this time, the rotary arm 42 provides a torque to the dust-proof member 40, and the dust-proof member 40 rotates backward under the torque to open the second through hole 31. When the dust-proof member 40 opens the second through hole 31, the rotary arm 42 swings upward, and at this time, the rotary arm 42 provides a torque to the dust-proof member 40, and the dust-proof member 40 rotates forward under the action of the torque to shield the second through hole 31.

In the present embodiment, the rotation shaft 41 and the rotation arm 42 are integrally formed. For example, the rotating shaft 41 and the rotating arm 42 may be punched by a process of punching a bar-shaped metal member.

In some embodiments, the driving mechanism 50 includes a push rod 51 and a cam 52, one end of the push rod 51 is connected to the rotating arm 42, the other end of the push rod 51 is connected to the cam 52, and the driving device 60 is used for driving the cam 52 to rotate, so as to push the push rod 51 to move to drive the rotating arm 42 to swing.

Thus, the cam 52 and the push rod 51 can be matched to convert rotary motion into movement, and the structure is simple. As shown in the orientation of fig. 2, the push rod 51 can push the rotary arm 42 to swing up and down when moving up and down, so that the dust-proof member 40 shields or opens the second through hole 31. In the present embodiment, the driving device 60 is an electric motor, and it is understood that an output shaft of the electric motor is connected to the cam 52, so that the driving device 60 drives the cam 52 to rotate when in operation, thereby driving the push rod 51 to reciprocate.

In some embodiments, one end of the push rod 51 is snapped into engagement with the swivel arm 42. In this way, the push rod 51 and the swivel arm 42 are easily attached and detached. Specifically, a clamping groove 511 is formed at one end of the push rod 51, a buckle 421 is formed at one end of the rotating arm 42, and the buckle 421 is clamped in the clamping groove 511, so that the push rod 51 and the rotating arm 42 are clamped together.

In some embodiments, the electronic device 200 includes a bracket 70, the bracket 70 is disposed on the housing 10, the driving device 60 and the driving mechanism 50 are both mounted on the bracket 70, the bracket 70 is formed with a limiting hole 71, and the push rod 51 is inserted into the limiting hole 71.

Thus, the bracket 70 can bear the parts such as the driving device 60 and the push rod 51, and the limiting hole 71 can limit the freedom degree of the push rod 51, so that the push rod 51 moves more stably. Specifically, the driving device 60 may be mounted on the bracket 70 by means of a snap-fit connection. In order to reduce friction between the push rod 51 and the bracket 70, the push rod 51 may be coated with lubricating oil.

In some embodiments, the driving mechanism 50 includes a resilient member 53 sleeved on the push rod 51, where the resilient member 53 is, for example, a spring, and two ends of the resilient member 53 respectively abut against the push rod 51 and the bracket 70 to keep the push rod 51 in contact with the cam 52.

Specifically, referring to fig. 2 and 3, the push rod 51 is formed with a shoulder 512, and one end of the elastic element 53 abuts against the shoulder 512 and the other end abuts against the bracket 70. As shown in fig. 2, when the cam 52 pushes the push rod 51 to move upward, the elastic member 53 compresses and provides a downward force to the push rod 51 so that one end of the push rod 51 is abutted against the cam 52, thereby allowing the cam 52 to continuously push the push rod 51 to move upward.

In one example, when the electronic device 200 is installed, the dustproof member 40, the electroacoustic element 20 and the rotating shaft 41 may be installed on the housing 10, and the driving device 60, the cam 52, the push rod 51 and the elastic element 53 may be installed on the bracket 70 to form a mounting module, then the mounting module is installed on the housing 10, and finally the push rod 51 is clamped with the rotating arm 42, so that the driving device 60 may drive the dustproof member 40 to rotate through the push rod 51 and other elements.

Specifically, referring to fig. 2 and 5, the driving unit 100 drives the dust-proof member 40 to rotate as follows: the driving device 60 drives the cam 52 to rotate, and the cam 52 pushes the push rod 51 to move up and down when rotating, and pushes the rotary arm 42 to swing when the push rod 51 moves up and down, so that the dust-proof member 40 rotates, and the dust-proof member 40 shields or opens the second through hole 31.

In some embodiments, when the electronic device 200 is talking, the driving device 60 drives the dust-proof member 60 to open the second through hole 31 through the driving mechanism 50, so that the user can talk smoothly.
