Because the functional requirements of users on electronic equipment are also increasing, especially in the sound emitting mode of electronic equipment, it is now common to set up an individual positive sound emitting structure (i.e. a structure emitting sound towards the display screen direction of the electronic equipment), an individual top sound emitting structure (i.e. a structure emitting sound towards the top end of the electronic equipment) or a side sound emitting structure (i.e. a structure emitting sound towards the side edge of the electronic equipment) in the electronic equipment to realize the stereo effect of the electronic equipment, thereby satisfying the requirements of users. However, as the size of the electronic device gradually tends to be miniaturized, and the sound emitting structure needs to satisfy a certain sound emitting area, there is not enough space in the electronic device to arrange a single front sound emitting structure and a single top sound emitting structure or a side sound emitting structure, so that in the design process of the electronic device, contradictions are generated on the requirements of the function and the size, and the design difficulty of the electronic device is increased.

Based on this, the embodiment of the application discloses a shell structure and an electronic device, and the shell structure is applied to the electronic device and used as a shell of the electronic device. Specifically, electronic equipment still includes earphone module and display screen except this shell structure, and earphone module and display screen all install in shell structure, utilize at shell structure setting with the biography sound passageway, first phonate hole and the second phonate hole of earphone module intercommunication, realize the biography sound of earphone module. It is thus clear that, adopt the shell structure of this application embodiment, the same sound conduction passageway of accessible first sound hole and second sound hole sharing and earphone module to can simplify shell structure's design and reduce and occupy shell structure's inner space, make shell structure can satisfy electronic equipment's miniaturized design demand. In addition, because the opening directions of the first sound outlet and the second sound outlet are different, the first sound outlet and the second sound outlet can form a stereo effect at the moment, so that the use experience of a user is improved.

In order to facilitate understanding of the connection relationship between the housing structure and the earphone module in the electronic device and the formation manner of the sound cavity (i.e. the sound transmission channel, the first sound outlet and the second sound outlet) of the housing structure, the following will further describe the technical solution of the present invention with reference to the embodiments and the drawings.

Referring to fig. 1 to 3 together, the present invention discloses an electronic device 200, wherein the electronic device 200 may be a mobile device such as a mobile phone, a tablet computer, a notebook computer, and an intelligent wearable device. Specifically, the electronic device 200 includes a housing structure 100, an earpiece module 210, a cover component 220, and a display screen 230. The housing structure 100 has a space for installing the display screen 230, the earphone module 210 is installed on the housing structure 100, the cover member 220 is installed on the side of the housing structure 100 where the display screen 230 is installed, and the cover member 220 is used for covering the sound cavity of the housing structure 100 corresponding to the earphone module 210.

Specifically, during actual installation, the earphone module 210 may be installed on one side of the housing structure 100, and the display screen 230 and the cover component 220 are installed on the other side of the housing structure 100, so that the internal space of the housing structure 100 may be reasonably utilized, which is beneficial to implementing a light and thin design of the electronic device 200. It is understood that in other embodiments, the earphone module 210 and the display screen 230 may be disposed on the same side of the housing structure 100.

Further, considering that the earphone module 210 and the display screen 230 are disposed on different sides of the housing structure 100, and usually, the sound outlet of the earphone module 210 is disposed on the side of the housing structure 100 where the display screen 230 is disposed, in order to implement sound transmission of the earphone module 210, a sound transmission channel and a sound outlet are disposed on the side of the housing structure 100 where the display screen 230 is disposed, and then the sound transmission channel is covered (i.e., connected to the housing structure 100) by the cover member 220, so that sound is finally emitted from the sound outlet on the housing structure 100. Specifically, the cover member 220 may be a separate member from the housing structure 100, and the two members may be connected by clamping, gluing, welding, or the like; alternatively, the cover member 220 may be integrally formed on the housing structure 100, i.e., an integral part with the housing structure 100.

Considering that both the earpiece module 210 and the cover component 220 are engaged with the housing structure 100, the following detailed description will be made in terms of the specific structure of the housing structure 100 and the engagement relationship between the earpiece module 210 and the cover component 220:

referring to fig. 4 to fig. 6, the housing structure 100 includes a base plate 10 and a side plate 20, the base plate 10 can be used for mounting the earphone module 210, a sound channel 30 is disposed on the base plate 10, and the sound channel 30 is used for transmitting sound emitted by the earphone module 210. The side plate 20 surrounds the outer edge of the substrate 10, and forms a space for accommodating the display screen 230 with the substrate 10. The side plate 20 is provided with a first sound outlet 40 opening along a first direction X, the side plate 20 is further provided with a second sound outlet 50 opening along a second direction Y, and the first sound outlet 40 and the second sound outlet 50 are communicated with the sound transmission channel 30, so that sound emitted by the earphone module 210 is output through the sound transmission channel 30 and the first sound outlet 40 and the second sound outlet 50.

The first direction X is the same direction as the display screen 230 on the housing structure 100, and the second direction Y is perpendicular to the first direction. That is, the first sound outlet 40 may realize a positive sound outlet, and the second sound outlet 50 may be directed to a top sound outlet or a side sound outlet. When the first sound outlet hole 40 is the ejecting sound and the second sound outlet hole 50 is the ejecting sound, the stereo effect of the electronic device 200 is better, and the ejecting sound is still provided for the user because the sound is easily shielded in the using process, so that the user is prevented from being influenced by the shielding object, the user can be ensured to effectively receive the sound of the electronic device 200 under any condition, and the use experience and convenience of the user can be improved. When the first sound outlet 40 is a top sound and the second sound outlet 50 is a side sound, the above situation is similar, and the description is omitted here.

It can be seen that the housing structure 100 disclosed in the embodiment of the present application is formed by the substrate 10 and the side plate 20 together, and a space for installing the display screen 230 may be formed, so as to fix the display screen 230 on the electronic device 200, and meanwhile, on the substrate 10 of the housing structure 100, other electronic components may also be disposed, that is, the substrate 10 may provide an installation space for the electronic components in the electronic device 200, and at this time, the earpiece module 210 is also disposed on the substrate 10. The sound transmission channel 30 for transmitting the earphone module 210 is disposed on the substrate 10, so that the sound of the earphone module 210 disposed inside the electronic device 200 can be transmitted to the outside of the electronic device 200, thereby facilitating the use of the user. Meanwhile, the side plate 20 is provided with the first sound outlet hole 40 and the second sound outlet hole 50 which are opened in different directions, and the first sound outlet hole 40 and the second sound outlet hole 50 are communicated with the sound transmission channel 30, so that the sound of the sound transmission channel 30 can be output in different directions.

In this embodiment, only one earphone module 210 is utilized, and sound is realized through the same sound transmission channel 30 through the first sound outlet hole 40 and the second sound outlet hole 50 which are opened along different directions, so that stereo sound is realized. That is, the shell structure 100 of the embodiment of the present application, through the rational design to the shell structure 100, has replaced the mode that needs set up earphone module and sound outlet structure respectively when realizing two directions sound outlet in the correlation technique, has effectively simplified the arrangement of the inside electronic components of electronic equipment 200, and then can adapt to the miniaturized requirement of electronic equipment 200 better.

In order to better understand the solution of the present embodiment, the present embodiment takes the electronic device 200 as a mobile phone, and the housing structure 100 as a square housing structure for example.

In some embodiments, the substrate 10 has a first end 11 and a second end 12 opposite to each other, and the first end 11 and the second end 12 are two ends of the substrate 10 along its own length. The sound transmission channel 30 is located at the first end 11, the first sound outlet hole 40 and the second sound outlet hole 50 are located at one side of the side plate 20 connected to the first end 11 of the base plate 10, and the side plate 20 includes a first surface 21 and a second surface 22 perpendicular to and connected to the first surface 21. The first surface 21 is disposed toward the display screen 230, that is, the first surface 21 can be an upper surface of the housing structure 100, and the second surface 22 can be a side surface or an end surface of the housing structure 100. A first sound outlet 40 is arranged on the first surface 21, the first sound outlet 40 is located at the center of the first surface 21 corresponding to the first end 11, a second sound outlet 50 is arranged on the second surface 22, and the projection of the second sound outlet 50 on the first surface 21 is staggered with the first sound outlet 40. That is, the sound channel 30 is disposed near the top end of the substrate 10 or the electronic device 200, and the first sound outlet 40 and the second sound outlet 50 are also disposed near the top end of the substrate 10 or the electronic device 200, so as to reduce the distance between the first sound outlet 40 and the second sound outlet 50 and the sound channel 30, and further enable the sound in the earphone module 210 to be transmitted to the first sound outlet 40 and the second sound outlet 50 more quickly, and further enable the positions of the first sound outlet 40 and the second sound outlet 50 to conform to the usage habit of the user, thereby improving the usage experience of the user.

In addition, the first sound outlet hole 40 is disposed at a position of the first surface 21 corresponding to the center of the first end 11, and when the user uses the electronic device 200 to perform an earpiece mode, the first sound outlet hole 40 can be disposed approximately corresponding to the ear of the user, so as to conform to an ergonomic design and facilitate the user. And through restricting the projection of second sound outlet 50 on first surface 21 and staggering the setting with first sound outlet 40, can avoid second sound outlet 50 and the overlapping setting of first sound outlet 40, reduced the condition in the space of sound transmission, effectively improve the sound effect of first sound outlet 40, second sound outlet 50.

Further, considering that the housing structure 100 is a mobile phone housing, in order to realize a light and thin design of a mobile phone, the width of the side plate 20 is generally small, and thus, when the second sound outlet 50 is disposed on the side plate 20, since the second sound outlet 50 emits sound from the top end, the size of the opening of the second sound outlet 50 is also limited by the width of the side plate 20, that is, the size of the opening of the second sound outlet 50 is very limited, and sound transmission often requires a sufficient sound emitting area, and the small opening of the second sound outlet 50 seriously affects the sound emitting effect of the second sound outlet 50. In this regard, the sound conduction channel 30 has a first transition surface 52 connected to an inner wall surface 51 of the second sound outlet hole 50, the first transition surface 52 serving to guide the sound transmitted to the second sound outlet hole 50 through the sound conduction channel 30, thereby enlarging the sound outlet area of the second sound outlet hole 50. Specifically, the first transition surface 52 may be an arc-shaped surface, and the first transition surface 52 may extend from one end of the sound transmission channel 30, which is communicated with the second sound outlet 50, to the inner wall surface 51 of the second sound outlet 50, so as to guide sound to be transmitted from the sound transmission channel 30 to the second sound outlet 50 through the first transition surface 52, enlarge the sound outlet area of the second sound outlet 50, and improve the sound outlet effect of the second sound outlet 50.

In some embodiments, the base plate 10 includes a first surface 13 and a second surface 14 opposite to each other, the first surface 13 is located in a space enclosed by the base plate 10 and the side plate 20, a sound transmission channel 30 and a mounting hole 15 penetrating through the first surface 13 to the second surface 14 are provided on the first surface 13, and the second surface 14 is used for providing the earpiece module 210 at a position corresponding to the mounting hole 15. Through setting up mounting hole 15 for the setting realizes the intercommunication at the acoustic channel 30 of first face 13 and the earphone module 210 of second face 14, and the sound of earphone module 210 can transmit to acoustic channel 30 via mounting hole 15 promptly, in order to avoid setting up earphone module 210 and acoustic channel 30 in the both sides of base plate 10, the unable condition of transmitting to acoustic channel 30 of sound of earphone module 210.

Further, the mounting hole 15 includes a first opening 151 and a second opening 152 opposite to each other, the first opening 151 is covered by the earphone module 210, the second opening 152 is communicated with the sound transmission channel 30, and the covering member 220 is connected to the second opening 152 and the sound transmission channel 30, so that the sound transmission channel 30 and the mounting hole 15 form a sealed sound cavity. Since the mounting holes 15 are disposed through the first and

second sides

13 and 14 of the substrate 10, when the earphone module 210 is disposed at a position of the second side 14 corresponding to the mounting holes 15, i.e., a position of the first opening 151, the earphone module 210 can seal the first opening 151, and the second opening 152 is still open. Since the sound in the housing structure 100 needs to be transmitted in a sealed space, a sealed sound cavity can be formed in the housing structure 100 by connecting the cover member 220 to the second opening 152 and the sound transmission channel 30 communicated with the second opening 152, so as to prevent the sound from leaking out during the transmission process.

Further, in actual installation, an installation boss 141 surrounding the first opening 151 may be disposed on the second surface 14, and an installation cavity 142 for accommodating the earpiece module 210 may be formed between the installation boss 141 and the first opening 151, at this time, the earpiece module 210 may be fitted in the installation cavity 142, so as to seal the first opening 151, and the installation boss 141 may also protect the earpiece module 210.

Furthermore, the earphone module 210 and the second surface 14 can be bonded through foam, so that the connection between the earphone module 210 and the second surface 14 is sealed, and the foam has a certain elastic deformation amount, so that when the earphone module 210 is extruded from the outside, the foam can provide a certain deformation space to further protect the earphone module 210.

In some embodiments, as shown in fig. 7 and 8, in order to cover the sound transmission channel 30 and the second opening 152 and simultaneously achieve communication between the earphone module 210 and the sound transmission channel 30, the first surface 13 is provided with a first groove 131 and a second groove 132, the mounting hole 15 is disposed on the bottom surface of the first groove 131, and at this time, the second opening 152 is communicated with the first groove 131. The second groove 132 is also disposed on the bottom surface of the first groove 131 and located on the outer periphery of the mounting hole 15, so that the second groove 132 is communicated with the second opening 152 and located on the outer periphery of the second opening 152, and the second groove 132 is used to form the sound transmission channel 30. Since the sound transmission channel 30 is sealed and the second groove 132 is open, the cover member 220 covers the second opening 152 and also covers the second groove 132, and at this time, the partial groove bottom surface of the first groove 131, on which the mounting hole 15 and the second groove 132 are not disposed, is used for connecting the cover member 220, so that the sound emitted from the earphone module 210 can be transmitted to the first sound outlet 40 and the second sound outlet 50 through the closed mounting hole 15 and the sound transmission channel 30.

Specifically, the first groove 131 may be a substantially square groove, the first groove 131 has a four-peripheral side, the second groove 132 is located at one side of the first groove 131, and the other side of the first groove 131 may be used to connect the cover member 220, so that the sound of the mounting hole 15 can be transmitted only through the second groove 132 and leaked along the other side of the first groove 131. More specifically, in order to improve the sealing effect, when the cover member 220 is connected to the first groove 131, the cover member may be connected by a back adhesive or a foam-combined sealant, as long as the other peripheral sides of the first groove 131 can be sealed, which is not particularly limited in this embodiment.

Further, since the cover member 220 is thin, the cover member 220 is easily broken when external force is applied thereto when the cover member 220 is covered on the second groove 132 and the second opening 152, and based on this, a first supporting portion 1321 for supporting the cover member 220 connected to the first groove 131 is provided on the groove bottom surface of the second groove 132. In this way, the cover member 220 can be supported by the first support portion 1321, so that the cover member 220 is prevented from being broken and the sealing performance of the sealed sound cavity is prevented from being affected. Specifically, the first supporting portion 1321 may be a boss or a protrusion protruding from the bottom surface of the second groove 132.
