Background

Electronic devices are usually configured with acoustic devices such as microphones and speakers, so as to realize the acoustic functions of the electronic devices. The acoustic device is usually installed in a casing of the electronic device, a sound guide channel is formed in the casing of the electronic device, and the acoustic device conducts sound through the sound guide channel, so that sound is collected from the environment or is emitted to the environment.

The sound guide channel needs to be directly communicated with the environment, the external port of the existing sound guide channel is covered with a mesh structure part in consideration of the appearance of the electronic equipment and the probability that the sound guide channel is blocked, and in the working process, sound can be transmitted through the sound guide channel and the mesh of the mesh structure part. However, after the electronic device is used for a long time, the mesh structure is easy to accumulate dust, and then a plugging phenomenon occurs, and further the sound guide channel is plugged. The mesh of the mesh structure is usually small and therefore not easy to clean by the user, eventually resulting in the acoustic performance of the acoustic device being affected. The phenomenon that acoustic performance of the existing electronic equipment is reduced after the electronic equipment is used for a period of time generally exists, and the use experience of a user is influenced finally.

In order to solve the problems, the invention adopts the following technical scheme:

The technical scheme adopted by the invention can achieve the following beneficial effects:

according to the electronic equipment disclosed by the embodiment of the invention, the elastic covering part and the driving mechanism are configured, and the driving mechanism drives the acoustic device to move, so that the elastic covering part is switched between the first state and the second state, and the change of the aperture of the sound guide hole of the elastic covering part is realized. In the working process of the acoustic device, the elastic covering part can be in the first state under the action of the driving mechanism, and the aperture of the sound guide hole is larger in the first state, so that sound conduction is smoothly realized. After the acoustic device finishes working, the elastic covering part is in a second state under the action of the driving mechanism, and the aperture of the sound guide hole is reduced in the second state.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, an electronic device according to an embodiment of the present invention includes an acoustic device 100, a driving mechanism 200, and an elastic cover 300.

The acoustic device 100 is a functional device for realizing the acoustic performance of the electronic device, and the acoustic device 100 may be a receiver, a speaker, a microphone, and the like, and the specific type of the acoustic device 100 is not limited in the embodiments of the present invention. In an embodiment of the present invention, the acoustic device 100 has a sound guide port 110, and the sound guide port 110 enables conduction of sound.

The elastic cover 300 has elasticity and is thus capable of being deformed by an external force. In the embodiment of the present invention, the elastic cover 300 has the sound guide hole 311, and the sound guide hole 311 enables the conduction of sound. The elastic cover 300 covers the sound guide opening 110.

The electronic device disclosed by the embodiment of the invention comprises a shell, and particularly, the elastic covering piece 300 can be arranged inside the shell or outside the shell. Under general conditions, electronic equipment can also include the display screen, and the display screen setting is on the casing, and the display screen coats and is stamped the printing opacity apron, and the printing opacity apron passes through the optics glue film bonding with the display screen and fixes. The edge of the light-transmitting cover plate is fixed on the shell in a lap joint mode and is fixedly connected with the shell, and therefore the light-transmitting cover plate and the display screen are integrally installed on the shell. In this case, the elastic cover 300 may also be fixed between the light-transmissive cover plate and the housing. Of course, there are various ways to mount the elastic covering member 300 on the electronic device, and the embodiment of the present invention is not limited thereto.

The driving mechanism 200 is in driving connection with the acoustic device 100, and the acoustic device 100 can move under the driving of the driving mechanism 200. The elastic cover 300 is deformable with the movement of the acoustic device 100 to switch between the first state and the second state. In the embodiment of the present invention, the driving mechanism 200 drives the acoustic device 100 to move, the movement of the acoustic device 100 interferes with the elastic cover 300, and the elastic cover 300 is deformed by the interference of the acoustic device 100. The state of the elastic cover 300 after the deformation is the first state, and the state of the elastic cover 300 before the deformation is the second state.

In the case where the elastic cover 300 is in the first state in which the hole diameter of the sound guide hole 311 is the first hole diameter and the sound guide hole 311 is communicated with the sound guide port 110, the sound guide port 110 and the sound guide hole 311 are communicated, and finally the transmission of sound can be achieved, the sound guide hole 311 is in the expanded state. Under the condition that the elastic covering member 300 is in the second state, the aperture of the sound guide hole 311 is the second aperture, the first aperture is larger than the second aperture, and when the driving mechanism 200 drives the acoustic device 100 to move back, the interference between the acoustic device 100 and the elastic covering member 300 is reduced, so that the aperture of the sound guide hole 311 can be reduced.

Through the above process, in the process of moving the acoustic device 100 toward the elastic cover 300, the second aperture of the sound guide hole 311 can be changed into the first aperture, so that the aperture of the sound guide hole 311 is increased, and the transmission of sound is realized. In the process that the acoustic device 100 moves away from the elastic cover 300, the interference of the acoustic device 100 on the elastic cover 300 is reduced, and the elastic cover 300 is restored by the elastic deformation of itself, so that the sound guide hole 311 is changed from the first aperture to the second aperture.

According to the electronic device disclosed by the embodiment of the invention, the elastic covering piece 300 and the driving mechanism 200 are configured, the driving mechanism 200 drives the acoustic device 100 to move, and further the elastic covering piece 300 is switched between the first state and the second state, so that the aperture of the sound guide hole 311 of the elastic covering piece 300 is changed. During the operation of the acoustic device 100, the elastic covering member 300 can be in the first state under the action of the driving mechanism 200, and in the first state, the aperture of the sound guide hole 311 is large, so that the sound conduction is smoothly realized. After the operation of the acoustic device 100 is completed, the elastic cover 300 is in the second state by the driving mechanism 200, and in the second state, the aperture of the sound guide hole 311 is reduced. In this case, since the hole diameter of the sound guide hole 311 is reduced, the problem that the sound guide hole 311 is closed can be alleviated.

As described above, the sound leading port 110 and the sound leading hole 311 communicate in the first state of the elastic cover 300. In order to further reduce the probability of blocking the sound guide holes 311 on the premise of achieving communication, in a preferable embodiment, the projection of each sound guide hole 311 may be located in the sound guide hole 110 in the axial direction of the sound guide hole 311. In this case, the aperture of the sound guide hole 311 is smaller than the aperture of the sound guide port 110, and it is possible to prevent foreign substances from entering the sound guide port 110 to some extent.

However, in the above case, since the hole diameter of the sound guide port 110 is large, the partial structure of the elastic covering member 300 is likely to collapse. Based on this, in a preferable scheme, the number of the sound guide ports 110 and the number of the sound guide holes 311 may be equal and are multiple, each sound guide port 110 is disposed opposite to one sound guide hole 311, and in the first state, each sound guide port 110 is communicated with one sound guide hole 311. In this case, the elastic cover 300 can be supported well by the acoustic device 100.

In the electronic device disclosed in the embodiment of the present invention, one sound guiding port 110 may be disposed opposite to and communicated with the plurality of sound guiding ports 311, and one sound guiding port 311 may also be disposed opposite to and communicated with the plurality of sound guiding ports 110. The embodiment of the present invention does not limit the number relationship between the sound guide port 110 and the sound guide hole 311.

As described above, the acoustic device 100 is driven by the driving mechanism 200 to move, thereby achieving deformation of the elastic cover 300. Specifically, the acoustic device 100 may have a gap with the elastic cover 300, and under the driving action of the driving mechanism 200, the acoustic device 100 moves a distance and then contacts with the elastic cover 300, and then as the acoustic device 100 continues to move, the elastic cover 300 deforms, so that the aperture of the sound guide hole 311 increases.

Of course, there may be no gap between the acoustic device 100 and the elastic cover 300. Based on this, in a more preferable aspect, the acoustic device 100 is in contact with the elastic cover 300 in the second state. In this case, the acoustic device 100 can immediately drive the elastic cover 300 to deform during the process of driving the acoustic device 100 towards the elastic cover 300 by the driving mechanism 200, which undoubtedly has the advantage of being more sensitive.

As described above, the electronic device disclosed in the embodiment of the present invention may include a housing, and the driving mechanism 200 may be disposed in the housing. The positional relationship of the driving mechanism 200 to the acoustic device 100 may be varied as long as the acoustic device 100 is driven to move as described above. Referring again to fig. 1 and 2, in a preferred embodiment, the driving mechanism 200 may be disposed on a side of the acoustic device 100 facing away from the elastic cover 300. In this case, the driving mechanism 200 can apply force to the acoustic device 100 by pushing and pulling well. In the embodiment of the present invention, the driving mechanism 200 may be various types, and the driving mechanism 200 is a linear motor, a hydraulic expansion member, a pneumatic expansion member, or the like, and the embodiment of the present invention does not limit the specific type of the driving mechanism 200.

As described above, in the case where the elastic cover 300 is in the second state, the aperture of the sound guide hole 311 becomes small. Specifically, in the second state, the aperture of the sound guide hole 311 may be zero, that is, in this case, the sound guide hole 311 is in the completely closed state. Of course, the scheme can certainly achieve the purpose of better anti-blocking.

Of course, in the case where the elastic cover 300 is in the second state, the aperture of the sound guide hole 311 may be larger than zero, and in this case, even if the driving mechanism 200 is damaged and the acoustic device 100 cannot move, the sound guide hole 311 is not completely closed, and the user may use at least the electronic device.

As mentioned above, the electronic device may include a housing, and referring to fig. 3-4 again, the elastic cover 300 may be provided with at least two positioning holes 321 distributed along an edge thereof, and the housing may include a positioning portion, such as a positioning protrusion. The positioning hole 321 cooperates with the positioning portion by positioning, so as to realize the installation of the elastic covering piece 300 on the housing.

In a more preferred aspect, the elastic cover 300 may include a first region 310 and a second region 320, and the second region 320 may be disposed around the first region 310. The positioning holes 321 are disposed on the second region 320, and the sound guide holes 311 are disposed on the first region 310. Since the positioning hole 321 is provided on the second region 320, and the positioning hole 321 is used for achieving the installation of the elastic covering member 300, the smaller the deformation of the second region 320 is, the more stable the installation of the elastic covering member 300 is. Meanwhile, since the sound guide hole 311 is opened in the first region 310, the larger the deformation of the first region 310, the more advantageous the change of the aperture of the sound guide hole 311. Based on this, the thickness of the first region 310 may be smaller than the thickness of the second region 320, or the elastic coefficient of the first region 310 may be smaller than the elastic coefficient of the second region 320.

In the embodiment of the present invention, the elastic covering member 300 may be made of an elastic material, and the structure of the elastic covering member 300 may be various, and in a specific embodiment, the elastic covering member 300 may be an elastic membrane. The elastic covering member 300 may be an elastic polymer material, for example, the elastic covering member 300 may be a silicone sheet. The embodiment of the present invention does not limit the specific type and material of the elastic covering member 300.

The electronic device disclosed by the embodiment of the invention can be a mobile phone, a tablet computer, an electronic book reader, a game machine, an intelligent watch, a vehicle-mounted navigator and other devices, of course, the electronic device can be of other types, and the embodiment of the invention does not limit the specific type of the electronic device.

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. Various modifications and alterations to this invention will become apparent to those skilled in the art.
