[0008] In a possible implementation, the sealing assembly further includes a constraint member located in the second cavity. The constraint member extends along the first direction, and an end of the constraint member is connected with the base body. The constraint member is arranged between the battery device and the back cover, and a side surface of the constraint member away from the battery device abuts against the back cover.

[0009] In a possible implementation, the battery device includes a connecting plate and a battery. The connecting plate is electrically connected with the battery. The connecting plate is located at an end of the battery facing the first cavity. The connecting plate is clamped between the front shell and the first sealing member.

[0010] In a possible implementation, one side of the battery facing the back cover has a groove extending along the first direction. The constraint member is at least partially located in the groove.

[0011] In a possible implementation, the base is at least one of a metal piece and a plastic piece; and / or, the constraint is at least one of a metal piece and a plastic piece.

[0012] In a possible implementation, the front shell and the back cover are connected through a middle frame.

In the application, the installation cavity is divided into the first cavity and the second cavity, the part of the back cover corresponding to the first cavity can be connected with other parts in the installation cavity by means of pasting double-sided adhesive or the like to reduce the vibration amplitude, and the part of the back cover corresponding to the second cavity cannot be connected with the battery device by pasting because the position of the part of the back cover corresponding to the second cavity corresponds to the battery device, and the connection between the back cover and the battery device will affect the normal operation of the battery device. Therefore, the vibration amplitude of the part of the back cover corresponding to the second cavity cannot be reduced by pasting, and therefore the sealing assembly needs to be arranged. When the loudspeaker sounds, the sound wave is isolated by the sealing assembly and can only propagate in the first cavity. Therefore, only the first cavity forms the back sound cavity of the loudspeaker at this time, and the sound wave cannot be transmitted in the second cavity. Therefore, the vibration amplitude of the part of the back cover corresponding to the second cavity can be reduced. When the user uses the mobile device, the user mainly grips the position where the second cavity is located. Therefore, reducing the vibration amplitude of the part of the back cover corresponding to the second cavity can effectively improve the user experience of the user using the mobile device.

[0032] The above-described drawings show certain embodiments of the present application. As these embodiments are described in more detail in the following detailed description, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the above-described drawings. The application is capable of other embodiments and of being practiced or being carried out in various ways. DETAILED DESCRIPTION

[0033] The exemplary embodiments will be described in detail herein below with reference to the attached drawings. The same or similar components are denoted by the same or similar reference numerals throughout the drawings and the detailed description. The following exemplary embodiments described in the detailed description are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0034] ​As the background art shows, a speaker is usually arranged on a mobile device, in order to obtain a large volume, stereo sound and the like, the speaker of some mobile devices is arranged in a back cavity open state, that is, the speaker is communicated with the inner cavity of the mobile device, so that the inner cavity of the mobile device serves as the back cavity of the speaker.

[0035] However, in this way, when the mobile device makes sound through the speaker, the sound wave generated thereby causes the back cover of the mobile device to vibrate with a large amplitude, affecting the use experience of the mobile device.

[0036] In view of the above technical problems, the present application provides a mobile device, which comprises a front shell, a back cover, a sealing assembly, a speaker and a battery device, the back cover is arranged on the front shell and defines an installation cavity with the front shell, the sealing assembly divides the installation cavity into a first cavity and a second cavity which are isolated from each other, the speaker is arranged in the first cavity, and the battery device is arranged in the second cavity. In the prior art, the entire installation cavity serves as the back cavity of the speaker, and when the speaker makes sound, the entire back cover vibrates with a large amplitude. In the present application, the installation cavity is divided into the first cavity and the second cavity, the part of the back cover corresponding to the first cavity can be connected to other parts of the installation cavity by means of pasting double-sided adhesive or the like, so as to reduce the vibration amplitude. The part of the back cover corresponding to the second cavity is located opposite the battery device, and connecting the back cover to the battery device will affect the normal operation of the battery device, so the vibration amplitude of this part of the back cover cannot be reduced by pasting. Therefore, the sealing assembly is arranged, and when the speaker makes sound, the sound wave is isolated by the sealing assembly and can only propagate in the first cavity. At this time, only the first cavity forms the back cavity of the speaker, and no sound wave enters the second cavity. Therefore, the vibration amplitude of the part of the back cover corresponding to the second cavity can be reduced, and when the user uses the mobile device, the user mainly holds the position where the second cavity is located. Reducing the vibration amplitude of this part can effectively improve the user's use experience of the mobile device.

[0037] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings:

[0038] Referring to Figure 1As shown, the mobile device 100 of the embodiment of the present application comprises a front shell 110, a back cover 120, a sealing assembly 140 and a loudspeaker 150, wherein the back cover 120 is combined on the front shell 110 and defines an installation cavity 130 together with the front shell 110; the sealing assembly 140 is arranged in the installation cavity 130, and the sealing assembly 140 divides the installation cavity 130 into a first cavity 131 and a second cavity 132 which are isolated from each other; the loudspeaker 150 is arranged in the first cavity 131; and a battery device 160 is arranged in the second cavity 132.

[0039] In the embodiment of the present application, the back cover 120 and the front shell 110 define the installation cavity 130 together, and the loudspeaker 150 and the battery device 160 are arranged in the installation cavity 130. In the prior art, the installation cavity 130 is an entirety, the sound wave emitted by the loudspeaker 150 propagates in the entire installation cavity 130, and the entire back cover 120 vibrates greatly when emitting sound. Especially when the loudspeaker 150 works in a low frequency band, the vibration of the back cover 120 is obvious, and long-time holding of the mobile device 100 by a user will cause hand numbness and affect the use experience of the user.

[0040] In order to reduce the vibration of the back cover 120, the part of the back cover 120 corresponding to the first cavity 131 can be pasted with double-sided adhesive tape to paste the back cover 120 and other elements in the first cavity 131, so as to reduce the vibration amplitude of the part. The specific pasting manner is not limited in the embodiment of the present application. However, the part of the back cover 120 corresponding to the second cavity 132 is pasted with the surface of the battery device 160, which will cause the battery device 160 to be unable to normally operate. Therefore, it is difficult to reduce the vibration amplitude of the entire back cover 120 by only pasting with double-sided adhesive tape, and thus the sealing assembly 140 needs to be arranged.

[0041] In a specific implementation, the first cavity 131 and the second cavity 132 are separated by the sealing assembly 140, the speaker 150 is located in the first cavity 131, and the battery device 160 is located in the second cavity 132. When the mobile device 100 makes sound through the speaker 150, the sound wave generated by the speaker 150 is blocked by the sealing assembly 140 and can only propagate in the first cavity 131 and cannot enter the second cavity 132. In this way, the part of the back cover 120 corresponding to the second cavity 132 will not vibrate due to the excitation of the sound wave, so as to reduce the vibration amplitude of the part. That is, the vibration amplitude of the part of the back cover 120 corresponding to the battery device 160 can be reduced without additionally arranging other devices on the surface of the battery device 160. In addition, since the user mainly holds the part of the mobile device 100 corresponding to the second cavity 132 when using the mobile device 100, reducing the vibration amplitude of the part of the back cover 120 can improve the use experience of the mobile device 100. The part of the back cover 120 corresponding to the first cavity 131 can be further reduced in vibration by the above-mentioned pasting and the like. Thus, the vibration amplitude of the entire back cover 120 can be reduced, and the embodiments of the present application do not limit this.

[0042] Thus, the mobile device 100 provided by the embodiments of the present application separates the mounting cavity 130 into the first cavity 131 and the second cavity 132 by the sealing assembly 140, isolates the sound wave generated by the speaker 150 in the first cavity 131, and thus reduces the vibration of the part of the back cover 120 corresponding to the second cavity 132, which is conducive to improving the use experience of the mobile device 100.

[0043] In some implementable manners, as shown in Figure 1 and Figure 2 , the first cavity 131 and the second cavity 132 of the embodiments of the present application are distributed along the first direction.

[0044] In a specific implementation, Figure 1 , the X direction is the first direction, the first cavity 131 and the second cavity 132 are distributed along the first direction, the speaker 150 is arranged at the part of the first cavity 131 away from the second cavity 132, that is, at the end of the mobile device 100, so that the position of the speaker 150 corresponds to the sound hole structure and the like on the mobile device 100.

[0045] In some implementable manners, as shown in Figure 1 , Figure 3 and Figure 4As shown, the sealing assembly 140 of the embodiment of the present application comprises a base body 141, a first sealing member 142 and a second sealing member 143, wherein the base body 141 extends along a second direction, the first sealing member 142 and the second sealing member 143 are respectively arranged on opposite sides of the base body 141 along a third direction, the first sealing member 142 is in sealing cooperation with the front shell 110, and the second sealing member 143 is in sealing cooperation with the rear cover 120; the first direction, the second direction and the third direction are perpendicular to each other in pairs.

[0046] It should be noted that, Figure 2 In the Y direction, the second direction, Figure 1 In the X direction, the first direction, and the Z direction, the third direction, the base body 141 can be selected from a material with high rigidity to ensure the supportability of the base body 141, and the first sealing member 142 and the second sealing member 143 can be selected from a flexible material with elasticity to ensure the sealing performance of the sealing assembly 140. Specifically, the first sealing member 142 is in sealing cooperation with the front shell 110, and the second sealing member 143 is in sealing cooperation with the rear cover 120, so as to ensure that the first cavity 131 and the second cavity 132 are isolated from each other and that the sound waves cannot enter the second cavity 132. The base body 141 is located between the first sealing member 142 and the second sealing member 143 and can serve as a support. Since the base body 141 has high rigidity, it can support the second sealing member 143, so that the second sealing member 143 is pressed against the rear cover 120, and the first sealing member 142 is pressed against the front shell 110. This can not only improve the sealing performance, but also support the rear cover 120 and further reduce the vibration of the rear cover 120.

[0047] In some possible implementation manners, referring to Figures 1 to 4 As shown, the sealing assembly 140 of the embodiment of the present application further comprises a constraint member 144 located in the second cavity 132. The constraint member 144 extends along the first direction, and an end of the constraint member 144 is connected with the base body 141. The constraint member 144 is arranged between the battery device 160 and the rear cover 120, and a side surface of the constraint member 144 away from the battery device 160 and the rear cover 120 abut against each other.

[0048] It can be understood that, although the sound waves cannot enter the second cavity 132, when the part of the rear cover 120 corresponding to the first cavity 131 is excited by the sound waves to vibrate, the part of the second cavity 132 corresponding to the part of the rear cover 120 may also vibrate synchronously. Therefore, the constraint member 144 can be arranged in the second cavity 132. The constraint member 144 can be made of a material with high rigidity, which is the same as the base body 141. The constraint member 144 is fixed at a predetermined position by being connected with the base body 141, so that the constraint member 144 abuts against the rear cover 120. In this way, the constraint member 144 can exert a pressure on the rear cover 120 along the third direction, thereby hindering the vibration of the rear cover 120 and further reducing the vibration of the rear cover 120, and improving the user experience of the mobile device 100.

[0049] In addition, the constraint member 144 can be independently arranged and fixed to the base body 141 by welding or the like, or can be integrally formed with the base body 141, so as to improve the connection stability of the constraint member 144 and the base body 141, improve the structural strength of the constraint member 144, and guarantee the damping effect of the constraint member 144. The specific connection mode of the constraint member 144 and the base body 141 is not limited in the embodiments of the present application.

[0050] In some implementable manners, referring to Figures 1 to 4 The battery device 160 of the embodiment of the present application includes a connecting plate 161 and a battery 162, the connecting plate 161 is electrically connected to the battery 162, the connecting plate 161 is located at one end of the battery 162 facing the first cavity 131, and the connecting plate 161 is clamped between the front shell 110 and the first sealing member 142.

[0051] In some embodiments, the connecting plate 161 is fixed with elements such as a wire harness, which is used to electrically connect the battery 162 and a circuit board in the mobile device 100. In order to avoid the elements on the connecting plate 161 being pressed, the connecting plate 161 is clamped between the front shell 110 and the first sealing member 142, and the first sealing member 142 is made of a flexible material. In this way, the sealing property of the sealing assembly 140 can be guaranteed, and the connecting plate 161 can be prevented from being damaged due to excessive pressure, so as to guarantee the stability of the electrical connection between the battery 162 in the second cavity 132 and the circuit board in the first cavity 131.

[0052] In some implementable manners, referring to Figures 1 to 4 The battery 162 of the embodiment of the present application has a groove 1621 extending in the first direction on the side facing the rear cover 120, and the constraint member 144 is at least partially located in the groove 1621.

[0053] In a specific implementation, the battery 162 can include a plurality of battery cells arranged side by side, and the gap between two adjacent battery cells forms the groove 1621 on the battery 162. When the groove 1621 is arranged on the battery 162, the constraint member 144 is partially located in the groove 1621, so as to reduce the space occupied by the constraint member 144 on the premise of avoiding the constraint member 144 pressing the battery 162.

[0054] In some implementable manners, referring to Figure 1 and Figure 3 The base body 141 of the embodiment of the present application is at least one of a metal member and a plastic member; and / or, the constraint member 144 is at least one of a metal member and a plastic member.

[0055] Specifically, since the constraint member 144 and the base 141 mainly play a supporting role, the purpose of the arrangement is to apply pressure to the back cover 120 in the third direction to hinder the vibration of the back cover 120, and therefore the constraint member 144 and the base 141 need to be arranged as at least one of a metal member and a plastic member to ensure that the rigidity of the constraint member 144 and the base 141 meets the supporting requirement.

[0056] In some implementable manners, referring to Figures 1 to 4 The mobile device 100 of the embodiment of the present application further includes a middle frame, and the front shell 110 and the back cover 120 are connected through the middle frame; and the sealing assembly 140 is connected with the middle frame.

[0057] It should be noted that the mobile device 100 is internally provided with a middle frame, which serves as a supporting framework of the mobile device 100 as a whole, and connects the front shell 110 and the back cover 120 together. The sealing assembly 140 and the constraint member 144 can be fixed at predetermined positions through the middle frame. The specific connection manner is not limited in the embodiment of the present application. For example, the opposite ends of the sealing assembly 140 and the end of the constraint member 144 away from the sealing assembly 140 can be connected with the middle frame through pasting, welding, bolt fixing or the like, so as to fix the sealing assembly 140 and the constraint member 144 at predetermined positions of the mounting cavity 130, and ensure the stability of the sealing assembly 140 and the constraint member 144, thereby ensuring the vibration reduction effect of the sealing assembly 140 and the constraint member 144 on the back cover 120.

[0058] In some implementable manners, referring to Figure 1 and Figure 3 The first sealing member 142 of the embodiment of the present application is at least one of a polyurethane member, an ethylene-vinyl acetate copolymer member, a silica gel member and a rubber member, and / or the second sealing member 143 is at least one of a polyurethane member, an ethylene-vinyl acetate copolymer member, a silica gel member and a rubber member.

[0059] It can be understood that, in order to ensure the sealing effect of the sealing assembly 140, the first sealing member 142 and the second sealing member 143 need to be selected from elastic materials with good sealing performance, so as to ensure that the first sealing member 142 and the second sealing member 143 are tightly connected with the front shell 110 and the back cover 120 respectively and with each other, and ensure that sound waves cannot be transmitted into the second cavity 132, which is conducive to ensuring the vibration reduction effect of the sealing assembly 140 and further improving the use experience of the mobile device 100.

[0060] In some implementable manners, referring to Figures 3 to 5As shown, the mobile device 100 provided by the embodiment of the present application further comprises a partition plate 170, the partition plate 170 is located in the first cavity 131, and one side of the partition plate 170 facing the second cavity 132 abuts against the sealing assembly 140; the partition plate 170 divides the first cavity 131 into a first chamber 1311 facing the back cover 120 and a second chamber 1312 facing the front shell 110, and the loudspeaker 150 is located in the second chamber 1312.

[0061] In this way, when the loudspeaker 150 emits sound, the sound wave generated by the loudspeaker 150 can only propagate in the second chamber 1312 due to the blocking of the sealing assembly 140 and the partition plate 170, that is, the second chamber 1312 serves as a back sound cavity of the loudspeaker 150, at this time, the sound wave excites the partition plate 170 to emit sound and vibrate, and the back cover 120 and the partition plate 170 have the first chamber 1311 therebetween and are not in direct contact, so the back cover 120 does not vibrate synchronously, which is beneficial to reduce the vibration of the part of the back cover 120 corresponding to the first cavity 131 and further improve the use experience of the mobile device 100.

[0062] In summary, the mobile device 100 provided by the embodiment of the present application comprises the front shell 110, the back cover 120, the sealing assembly 140, the loudspeaker 150 and the battery device 160, the front shell 110 and the back cover 120 jointly enclose the mounting cavity 130, the sealing assembly 140 divides the mounting cavity 130 into the first cavity 131 and the second cavity 132, the partition plate 170 is further arranged in the first cavity 131, the partition plate 170 divides the first cavity 131 into the first chamber 1311 close to the back cover 120 and the second chamber 1312 away from the back cover 120, the loudspeaker 150 is arranged in the second chamber 1312, the battery device 160 is arranged in the second cavity 132, the second chamber 1312 serves as a back sound cavity of the loudspeaker 150, when the loudspeaker 150 emits sound, the sound wave is blocked in the second chamber 1312 by the partition plate 170 and the sealing assembly 140, so the sound wave cannot enter the first chamber 1311 and the second cavity 132, thus the back cover 120 can be prevented from vibrating greatly due to the excitation of the sound wave, and the sound wave only excites the partition plate 170 to vibrate, and the partition plate 170 is not in direct contact with the back cover 120, so the back cover 120 does not vibrate synchronously, thereby the vibration of the back cover 120 is reduced, which is beneficial to improve the use experience of the mobile device 100.
