When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification.

[0034] The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. Unless otherwise defined, technical and scientific terms used in this specification and the appended claims should have the meaning commonly understood by one of ordinary skill in the art to which this disclosure belongs.

Also, the use of the terms "one" or "a" or "an" do not denote a limitation of quantity but rather denote the presence of one or more of the referenced items. The use of the term "or" in reference to a list of items means that at least one of the items, but not necessarily more than one of the items is encompassed by the term. The use of the terms "front", "back", "lower", and / or "upper" are used for convenience and are not intended to be limiting as to a particular orientation with respect to one another or the spatial orientation of the device.

[0035] The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The use of the terms "a" and "the" and "said" in this specification and the appended claims is not meant to denote a limitation on the number of entities referenced by these terms. Also, the use of the term "or" in reference to a list of items should be understood to mean that at least one of the items, but not necessarily more than one of the items is encompassed by the term.

[0036] An electronic device generally includes a speaker assembly for implementing a corresponding playing function. As the requirement for thinness of the electronic device increases, the speaker assembly also needs to be thinned. In the related art, a half-cavity speaker containing only a front cavity is formed by using a speaker housing and a sound-producing body, and a rear cavity is obtained by sealing the electronic device housing and the speaker housing, the above scheme can effectively thin the speaker assembly, but there is a risk that water leaking into the speaker will leak into the internal part of the electronic device.

[0037] It should be noted that the requirements for waterproofing levels of electronic devices are different in different use scenarios, and when the waterproofing level of the electronic device is required to be high, a waterproof structure matching the waterproofing level needs to be set. For example, taking a seal formed by an injection body as an example, when the width of the injection body is a first size, the waterproofing requirement of IP65 level can be met, and when the waterproofing level increases to IP68, the width of the injection body needs to be increased from the first size to a second size. The increase in the width of the injection body is easy to cause the seal to fail due to the shrinkage of the plastic during the injection process.

[0038] The present disclosure provides a speaker assembly.Figure 1 is a perspective exploded structural schematic diagram of a loudspeaker in an example embodiment of the present disclosure, Figure 2 is a cross-sectional structural schematic diagram of a loudspeaker assembly in an example embodiment of the present disclosure, Figure 3 is a perspective structural schematic diagram of a structural member in an example embodiment of the present disclosure, Figure 4 is a perspective structural schematic diagram of a loudspeaker assembly in an example embodiment of the present disclosure, Figure 5 is a perspective structural schematic diagram of a loudspeaker assembly in another example embodiment of the present disclosure, as shown in Figures 1-5 The loudspeaker assembly 1 includes a housing 12 and a sound emitting body 11 assembled to the housing 12, and the housing 12 includes a housing body 121, a structural member 122, and an injection molded body 123. The housing body 121, the structural member 122, and the sound emitting body 11 enclose a front cavity 14, and the housing body 121 is provided with a first opening 1212 communicating the front cavity 14 and the outside of the loudspeaker assembly 1. The structural member 122 includes a first region 1226 located at the periphery of the sound emitting body 11, and the first region 1226 is provided with a through hole 1223 penetrating the structural member 122. The injection molded body 123 includes a glue presenting structure 1231 and an extension structure 1232, the glue presenting structure 1231 is located around the sound emitting body 11 to form a seal between the glue presenting structure 1231 and the sound emitting body 11. The extension structure 1232 connects the glue presenting structure 1231 and the outer side of the structural member 122 opposite to the glue presenting structure 1231 through the through hole 1223 to fix the structural member 122.

[0039] In the above embodiment, the housing body 121, the structural member 122, and the sound emitting body 11 enclose the front cavity 14, and the structural member 122 independent of the housing body 121 can thin the thickness of the housing 12 by using its own structural properties. In addition, the injection molded body 123 of the housing 12 includes the glue presenting structure 1231 and the extension structure 1232, the glue presenting structure 1231 is located around the sound emitting body 11 to form a seal between the glue presenting structure 1231 and the sound emitting body 11, and the extension structure 1232 connects the glue presenting structure 1231 and the outer side of the structural member 122 opposite to the glue presenting structure 1231 through the through hole 1223 of the structural member 122 to fix the structural member 122. The above-mentioned extension structure 1232 enhances the fixing reliability of the structural member 122, avoids the seal failure caused by the separation from the structural member 122 due to the volume shrinkage after injection molding, and helps to improve the waterproof performance of the loudspeaker assembly 1 and the electronic device.

[0040] In some embodiments, the through holes 1223 are uniformly distributed around the sound emitting body 11 in the first region 1226, which can form the glue presenting structure 1231 along the periphery of the sound emitting body 11 and the uniformly distributed extension structure 1232 through each through hole 1223 when the injection molded part is formed, thereby improving the fixing stability and reliability of the structural member 122. For example, the first region 1226 can beFigure 1 The half-frame structure with a preset width is shown by a dashed line, and the preset width of the half-frame structure can be indicated by W. When the diameter of the through hole 1223 is slightly smaller than the width W of the half-frame structure, the through hole 1223 can be arranged at the periphery of the sound production body 11 along the frame structure. Alternatively, the first area 1226 described above can also be a rectangular frame, a circular ring, an irregular structure, or the like with a preset width, and the present disclosure does not limit this.

[0041] In other embodiments, the through hole 1223 can also be arranged at the periphery of the sound production body 11 in a non-uniform manner according to specific fixed connection requirements, and the present disclosure does not limit the arrangement scheme of the through hole 1223.

[0042] In the above embodiments, as shown in Figure 6 The structure 122 includes oppositely arranged inner surfaces 1224 and outer sides 1225, and the through hole 1223 includes oppositely arranged first and second end surfaces. The cross-sectional area of the first end surface of the through hole at the outer side 1225 is greater than that of the second end surface. When the extension structure 1232 is formed, a structure with a smaller cross-sectional area at the second end surface than at the first end surface can be obtained, avoiding the extension structure 1232 from being pulled out of the through hole 1223.

[0043] The connection between the through hole 1223 and the outer side 1225 is provided with an arc-shaped edge to improve the flow smoothness of the injection molded body 123 during the molding process and reduce the molding difficulty of the extension structure 1232.

[0044] In some embodiments, the structure 122 can be a plate structure, and the through hole 1223 is a through hole 1223 obtained by cutting part of the structure on both sides of the plate structure.

[0045] Alternatively, the structure 122 can be a plate structure, and the depth of the through hole 1223 is greater than the thickness of the plate structure. For example, the through hole 1223 can also be a through hole 1223 obtained by drawing and punching on the plate structure. The structure protruding towards the sound production body 11 after drawing and punching deformation and the hole position on the plate structure together form the through hole 1223, and the depth of the through hole 1223 is greater than the thickness of the plate structure to improve the glue grabbing reliability. In other embodiments, the structure 122 can include a plate structure and a protrusion on the side of the plate structure facing the sound production body 11. By cutting part of the structure at the protrusion position, the depth of the through hole 1223 can be greater than the thickness of the plate structure to improve the glue grabbing reliability.

[0046] In embodiments of the present disclosure, the material of the shell body 121 can be plastic, rubber, metal, etc., and the present disclosure does not limit this. The material of the structural member 122 can be selected to have a structural strength greater than that of the shell body 121, so that the structural member 122 has a thin and light attribute while achieving the desired structural strength. For example, the material of the structural member 122 can be metal or alloy.

[0047] Taking the material of the structural member 122 as steel and the structure of the shell body 121 as plastic as an example, the structural member 122 can be formed integrally with the shell body 121 as an insert during injection molding of the shell body 121. Alternatively, the structural member 122 and the shell body 121 can be assembled and fixed by clamping, bonding or other means, and the present disclosure does not limit this. Since the structural member 122 is made of steel and has good structural strength, the thickness of the structural member 122 can be thinner than that of the shell body 121, and when the two are combined to form the shell 12, the overall thickness of the shell 12 can be reduced, improving the thinness of the shell 12 and the loudspeaker assembly 1.

[0048] In some embodiments, the shell body 121 has a second opening 1211 on one side in the thickness direction of the loudspeaker assembly 1, and the structural member 122 blocks the second opening 1211. By arranging the structural member 122 at the second opening 1211 on one side of the shell body 121, the molding convenience of the structural member 122 and the overall thinness of the shell 12 can be improved.

[0049] In some embodiments, the structural member 122 includes an intermediate portion 1221 and at least one glue-catching structure 1222 arranged at the edge of the intermediate portion 1221, and the at least one glue-catching structure 1222 is bent relative to the intermediate portion 1221. When the shell body 121 is injection molded, the glue-catching structure 1222 can catch the plastic structure of the shell body 121, improving the connection reliability of the structural member 122 and the shell body 121.

[0050] In some embodiments, the shell body 121 is assembled to the device shell 2112, and the device shell 2112, the shell body 121 and the sound emitting body 11 enclose the rear cavity 15. Forming the rear cavity 15 by means of the device shell 2112 helps to reduce the overall thickness of the loudspeaker assembly 1 and can reduce the space occupied by the loudspeaker assembly 1.

[0051] In some embodiments, the loudspeaker assembly 1 further includes a waterproof and breathable membrane 13, which is assembled to the shell body 121 and covers the first opening 1212. The waterproof and breathable membrane 13 can prevent external liquid from entering the front cavity 14 through the first opening 1212 at a certain waterproof level, and can form a basic waterproof effect.

[0052] When the loudspeaker assembly 1 is in a water-in scenario greater than the waterproof level of the waterproof and breathable film 13, the external liquid enters the front cavity 14, but the injection molding part and the glue between the injection molding part and the sound generating body 11 can form a reliable seal to prevent the external liquid from entering the rear cavity 15 and the internal part of the electronic device.

[0053] The present disclosure further provides an electronic device, which comprises the above loudspeaker assembly 1.

[0054] The shell body 121, the structural part 122 and the sound generating body 11 enclose the front cavity 14, and the structural part 122 independent of the shell body 121 can thin the thickness of the shell 12 by using its own structural properties. In addition, the injection molding body 123 of the shell 12 comprises a glue structure 1231 and an extension structure 1232, the glue structure 1231 is located around the sound generating body 11 to form a seal between the glue structure 1231 and the sound generating body 11, and the extension structure 1232 connects the glue structure 1231 and the outer side of the structural part 122 opposite to the glue structure 1231 through the through hole 1223 of the structural part 122 to realize the fixation of the structural part 122. The above-mentioned extension structure 1232 strengthens the fixation reliability of the structural part 122, avoids the seal failure caused by the volume shrinkage and glue shrinkage after injection molding, and helps to improve the waterproof performance of the loudspeaker assembly 1 and the electronic device.

[0055] It should be noted that the above-mentioned electronic device can be a mobile phone, a tablet computer, a smart speaker, a vehicle-mounted terminal, a medical terminal, a wearable device, a robot, etc., and the present disclosure does not limit this.

[0056] The above is only the preferred embodiment of the present disclosure, and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as the above preferred embodiment, it is not intended to limit the present disclosure. Any person skilled in the art can make some changes or modifications to the above-mentioned disclosed technical content without departing from the scope of the technical solution of the present disclosure, and any simple modification, equivalent change and modification of the above-mentioned embodiment according to the technical essence of the present disclosure are still within the scope of the technical solution of the present disclosure.
