Taking the electronic device as a mobile phone as an example, the speaker in the mobile phone includes a core and a sealing metal sheet, and the diaphragm of the core and the sealing metal sheet of the speaker form a front cavity of the speaker, and the front cavity is connected to the sound outlet of the speaker. The diaphragm can vibrate in the front cavity, so that the speaker can make sounds, and in order to ensure the normal function of the speaker, it is necessary to have a good seal between the sound outlet of the speaker and the middle frame of the mobile phone, and a good seal is generally achieved by a sufficient sealing width. If the sealing width is insufficient, audio leakage and liquid inflow into the sound outlet are prone to occur, which can easily cause the speaker to malfunction; accordingly, the sealing scheme adopted by the speaker is: the sound outlet and the middle frame are sealed by a sealing ring, so that the projection height of the sealing structure in the height direction of the speaker includes the upper width projection of the sealing ring, the height of the sound outlet and the lower width projection of the sealing ring. Therefore, for the thinning of electronic devices, after the speaker itself is thinned, the sealing structure needs to be designed to ensure the normal function of the speaker. Summary of the invention

[0003] The present application provides a speaker sealing structure, a housing assembly and an electronic device, so that after the speaker itself is thinned, the speaker sealing structure is utilized to ensure the normal function of the speaker.

In this way, the soft sealing strip can be elastically deformed during assembly to ensure that the first sound outlet hole and the sound outlet of the speaker are connected. The sound is not easy to leak from the connection between the sealing frame and the speaker, thereby ensuring the sound quality of the speaker. In addition, the edge seal is used to achieve the sealing between the front cavity of the speaker and the shell of the electronic device, thereby ensuring the sealing between the front cavity and the shell.

DETAILED DESCRIPTION

[0062] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0063] It should be understood that the "multiple" mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0064] In related art, see Figure 1As shown, the speaker in the mobile phone (abbreviated as: SPK-BOX, full name in English: Speaker BOX) includes a core and a sealing metal sheet 11. The front cavity of the speaker is formed between the diaphragm of the core and the sealing metal sheet of the speaker. The front cavity of this type of speaker is closed; the front cavity is connected to the sound outlet 12 of the speaker, and the diaphragm can vibrate in the front cavity, so that the speaker can make sound. In order to ensure the normal function of the speaker, it is necessary to have a good seal between the sound outlet of the speaker and the middle frame of the mobile phone. A good seal is generally achieved by a sufficient sealing width. If the sealing width is insufficient, audio leakage and liquid ingress into the sound outlet are likely to occur, which may easily cause the speaker to malfunction. Accordingly, the sealing scheme adopted by the speaker is: a sealing ring 13 is passed between the sound outlet 12 and the middle frame 14. The sealing is performed, so that the projected height of the sealing structure in the height direction of the speaker includes the upper width projection of the sealing ring 13, the height of the sound outlet 12 and the lower width projection of the sealing ring 13, wherein the height direction of the speaker is parallel to the thickness direction of the mobile phone; in order to thin the speaker, a speaker with an open front cavity is designed, so that the speaker with an open front cavity omits the sealing metal sheet 11 compared to the speaker with a closed front cavity, so that the thickness of the speaker with an open front cavity can be thinned, and for the speaker with an open front cavity, in order to ensure its sealing, its sealing structure needs to be redesigned to ensure its sealing, thereby ensuring that the speaker with an open front cavity functions normally. Therefore, an embodiment of the present application provides a speaker sealing structure to solve the problem of the sealing performance of the speaker with an open front cavity. At the same time, the present application also provides a shell assembly with the speaker sealing structure to use an electronic device with the shell assembly.

In this way, the soft sealing strip 104 can be elastically deformed during assembly to ensure that the first sound outlet hole 103 and the sound outlet 310 of the speaker are connected. In this way, sound is not easily leaked from the connection between the sealing frame 101 and the speaker, thereby ensuring the sound quality of the speaker. In addition, the edge seal 102 is used to achieve the sealing between the front cavity 309 of the speaker and the shell of the electronic device, thereby ensuring the sealing between the front cavity 309 and the shell.

[0083] In some embodiments, the sealing frame 101 is made of a hard material, which can provide support for the dustproof net 206 and facilitate the installation of the dustproof net 206. The hard material can be metal or plastic, the metal can be aluminum alloy or stainless steel; the plastic can be polycarbonate plastic, polyvinyl chloride plastic or acrylonitrile-butadiene-styrene copolymer plastic.

[0084] In some embodiments, the edge seal 102 is made of foam, which is beneficial to weight reduction and ensures good sealing. The foam can be installed on the housing of the electronic device through adhesive, which can ensure the stability of the foam installation.

[0085] See also Fig.16 and Fig.18 As shown, in one or more embodiments, the present application also provides a housing assembly, which includes a housing and a speaker sealing structure in any embodiment, the housing includes a substrate 201 and a frame 202, the frame 202 is arranged around the substrate 201; the sealing frame 101 is installed at the connection between the frame 202 and the substrate 201, and the edge seal 102 is fixed on the substrate 201, so that after the speaker sealing structure is installed on the housing, it is helpful to ensure the normal function of the speaker. The first sub-surface 116 is opposite to the frame 202, and the second sub-surface 117 is opposite to the substrate 201.

[0086] For example, when the electronic device is a mobile phone, the housing can be the middle frame of the mobile phone; a second sound outlet through hole is opened on the frame 202, and the first sound outlet through hole 103 of the sealing frame 101 is connected to the second sound outlet through hole, so as to achieve the transmission of the sound emitted by the speaker; the number of the second sound outlet through holes can be multiple, and the second sound outlet through holes can be circular through holes; see Fig. 20 As shown, the middle frame has a top 203 and a bottom 204 relative to each other in the length direction. The top 203 of the middle frame is generally where the camera of the mobile phone is located, and the bottom 204 of the middle frame is generally where the charging port of the mobile phone is located. A second sound outlet hole is provided at the top 203 of the middle frame, and / or a second sound outlet hole is provided at the bottom 204 of the middle frame. Since the second sound outlet hole can be provided at the top 203 or the bottom 204 of the middle frame, a speaker can be installed at the top 203 or the bottom 204 of the middle frame. Fig.18 and Fig.19 As shown, the corresponding speaker sealing structure can be set at the top 203 of the middle frame; combined with Fig.16 and Fig.17 As shown, a corresponding speaker sealing structure may also be provided at the bottom 204 of the middle frame.

In this way, by opening the preset through hole 205 on the substrate 201, the front cavity 309 of the speaker and the preset through hole 205 can form a larger space together, that is, the front cavity 309 of the speaker and the preset through hole 205 together form the vibration space of the speaker, which has the effect of expanding the sound of the speaker. In one embodiment, the edge seal 102 can be bonded to the substrate 201 by adhesive, which is conducive to ensuring the stability of the connection and the sealing during use. The edge contour of the preset through hole 205 is adapted to the edge contour of the front cavity 309 of the speaker, that is, the orifice area of ​​the preset through hole 205 is the same or substantially the same as the cavity area of ​​the front cavity 309 of the speaker, which is conducive to ensuring the sound quality of the speaker. It should be noted that the orifice area of ​​the preset through hole 205 can also be larger than the cavity area of ​​the front cavity 309 of the speaker, which is conducive to increasing the vibration space of the speaker; of course, the orifice area size of the preset through hole 205 can also be adjusted according to other situations.

[0088] See also Figure 3 and Fig.10 As shown, in some embodiments, the shell assembly also includes a dustproof net 206, and the dustproof net 206 is connected to the sealing frame 101. Since the dustproof net 206 is thin or soft, it can be installed on the sealing frame 101 first, and then the sealing frame 101 is installed on the shell, thereby realizing the installation of the dustproof net 206. The dustproof net 206 can reduce the entry of foreign matter into the front cavity 309 of the speaker, thereby ensuring the sound quality of the speaker. In one embodiment, one side of the dustproof net 206 is bonded to the second side surface 115 of the sealing frame 101 by adhesive, and the other side opposite to the dustproof net 206 is bonded to the shell of the electronic device, for example, the middle frame of a mobile phone by adhesive; in the specific assembly process, the dustproof net 206 can be bonded to the sealing frame 101 by adhesive, and then adhesive is affixed to the other side opposite to the dustproof net 206, and finally, the sealing frame 101 is installed in the corresponding position of the shell of the electronic device, so that the adhesive on the other side opposite to the dustproof net 206 is bonded to the shell of the electronic device.

[0089] Combination Figure 3 and Figure 5As shown, in one embodiment, when the first sub-surface 116 and the second sub-surface 117 are connected by the transition curved surface 118, the first sub-surface 116, the second sub-surface 117 and the transition curved surface 118 are all covered with a backing adhesive bonded to the dustproof net 206, so as to conveniently improve the installation stability of the sealing frame 101; in addition, the dustproof net 206 is supported by the sealing frame 101 to achieve the coordination between the dustproof net 206 and the arc surface of the middle frame, and while ensuring the sealing width at both ends of the sound outlet 310, the width of the sound outlet 310 is expanded, thereby improving the audio performance and realizing the overall dustproof and waterproof properties of the mobile phone.

[0090] Combination Fig.10 and Fig.12 As shown, in another embodiment, when there is an edge 119 at the connection between the first sub-surface 116 and the second sub-surface 117, only the first sub-surface 116 is covered with a backing adhesive bonded to the dustproof net 206, so that the dustproof net 206 and the first sub-surface 116 are connected in a planar bonding manner. In this way, the sealing frame 101 as a supporting structure is more conducive to the assembly of the dustproof net 206 through a planar bonding method, and the sealing frame 101 and the middle frame are more effectively ensured to be sealed.

[0091] Combination Fig. 20 and Fig.21 As shown, in one or more embodiments, the present application further provides an electronic device, which includes a speaker and a housing assembly in any embodiment; the speaker includes a box body 301 and a core 302, the box body 301 has an open cavity, the core 302 is installed in the cavity, and the diaphragm of the core 302 faces the open side of the cavity;
