Description

Technical Field

[0001] This application belongs to the field of acoustic technology, specifically relating to a loudspeaker module and electronic device. Background Technology

[0002] In the field of acoustic technology, sound-absorbing particles are usually filled inside the speaker module housing to improve the acoustic performance of the speaker module.

[0003] In related technologies, the speaker module housing has openings through which sound-absorbing particles are filled. To ensure that the sound-absorbing particles can flow smoothly to all positions within the speaker housing, channels need to be reserved at the locations of the speaker units within the housing for the sound-absorbing particles to pass through. Therefore, certain requirements are placed on the structural design of the speaker housing. Moreover, sound-absorbing particles are highly mobile and fluid, and in some areas within the speaker housing, there may be a high density of sound-absorbing particles, leading to uneven distribution of the particles and consequently affecting the acoustic performance of the speaker module. Summary of the Invention

[0004] The purpose of this application is to provide a speaker module and electronic device that can solve the problem of poor acoustic performance of speaker modules in related technologies.

[0005] In a first aspect, embodiments of this application provide a loudspeaker module, including a housing, a loudspeaker unit, and a sound-absorbing structural component. The loudspeaker unit and the sound-absorbing structural component are both disposed within the housing. The sound-absorbing structural component has a plurality of channels, and at least a portion of the plurality of channels extends to the surface of the sound-absorbing structural component. The duct is filled with sound-absorbing particles, which are confined within the duct and can move relative to the sound-absorbing structure along the extension direction of the duct to be distributed at different positions in the duct.

[0006] Secondly, embodiments of this application also provide an electronic device, including a device housing and the aforementioned speaker module, wherein the speaker module is disposed in the device housing.

[0007] In this embodiment, a sound-absorbing structure is added inside the speaker housing. The sound-absorbing structure is filled with sound-absorbing particles through its channels. While the sound-absorbing structure itself has a sound-absorbing function, it also serves as a supporting skeleton for the sound-absorbing particles, supporting and limiting their movement. This ensures that the sound-absorbing particles have a certain degree of mobility within the channels, allowing them to flow to different positions within the sound-absorbing structure and subsequently to different positions within the speaker housing. At the same time, the walls of the channels limit the movement of the sound-absorbing particles, preventing excessive movement that could lead to localized density or sparseness. The multiple channels make the distribution of sound-absorbing particles more uniform within the speaker housing, which is beneficial for improving the uniformity of particle distribution and enhancing the acoustic performance of the speaker module.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The speaker module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0013] Please refer to Figures 1 to 3 The speaker module disclosed in this application includes a speaker housing 100, a speaker unit 200, and a sound-absorbing structural component 300. The speaker housing 100 serves as the outer shell of the speaker module and is used to install the speaker unit 200 and the sound-absorbing structural component 300. The speaker housing 100 forms the rear cavity of the speaker module. The speaker unit 200 serves as a sound-emitting unit and realizes the sound-emitting function. The sound-absorbing structural component 300 is filled with sound-absorbing particles 400.

[0014] Both the loudspeaker driver 200 and the sound-absorbing structural component 300 are disposed within the loudspeaker housing 100. Optionally, the loudspeaker driver 200 can be disposed within the loudspeaker housing 100 by means of welding, bonding, etc., and the sound-absorbing structural component 300 is located in the space within the loudspeaker housing 100 other than the loudspeaker driver 200; the sound-absorbing structural component 300 can contact the inner wall surface of the loudspeaker housing 100, and the sound-absorbing structural component 300 directly abuts against the inner wall surface of the loudspeaker housing 100, without the need for further connection between the sound-absorbing structural component 300 and the inner wall surface of the loudspeaker housing 100.

[0015] The sound-absorbing structural member 300 is provided with a plurality of channels 300a, at least a portion of which extends to the surface of the sound-absorbing structural member 300. Specifically, a portion of each channel 300a may extend to the surface of the sound-absorbing structural member 300, or each channel 300a may extend to the surface of the sound-absorbing structural member 300. Optionally, one end of a channel 300a may extend to the surface of the sound-absorbing structural member 300, or both ends of the same channel 300a may extend to the surface of the sound-absorbing channel. In short, the channels 300a form openings on the surface of the sound-absorbing structural member 300, through which sound-absorbing particles 400 can be filled.

[0016] The duct 300a can be a circular duct 300a, a square duct 300a, etc. The embodiments of this application do not limit the specific structural form of the duct 300a.

[0017] Sound-absorbing particles 400 are filled into the duct 300a. The sound-absorbing particles 400 enter the duct 300a through openings formed on the surface of the sound-absorbing structure 300. Optionally, each duct 300a is filled with sound-absorbing particles 400, or a portion of the ducts 300a is filled with sound-absorbing particles 400. The sound-absorbing particles 400 are in contact with the wall of the duct 300a, are confined within the duct 300a, and can move relative to the sound-absorbing structure 300 along the extension direction of the duct 300a to be distributed at different positions in the duct 300a, so that different positions in the duct 300a are respectively filled with sound-absorbing particles 400.

[0018] Specifically, the sound-absorbing structural component 300 serves as the supporting framework for the sound-absorbing particles 400. It incorporates pores 300a to fill the sound-absorbing particles 400, thus restricting their movement. Simultaneously, the sound-absorbing structural component 300 is breathable, allowing sound waves to penetrate and be absorbed by the sound-absorbing particles 400, ensuring acoustic performance. Optionally, the sound-absorbing structural component 300 can be a porous foam, a sintered fiber body, etc. In short, the sound-absorbing structural component 300 should be both breathable and able to restrict the movement of the sound-absorbing channels by filling the pores 300a with sound-absorbing particles 400.

[0019] Optionally, the sound-absorbing structural member 300 can be a cubic structure, with only one end of the channel 300a extending to the upper surface of the sound-absorbing structural member 300. Sound-absorbing particles 400 are filled into the channel 300a through the opening on the upper surface of the sound-absorbing structural member 300. In this case, the sound-absorbing structural member 300 itself confines the sound-absorbing particles 400 within the channel 300a, eliminating the need for other sealing structures to block the opening, and preventing the sound-absorbing particles 400 from falling out of the channel 300a. Alternatively, both ends of the channel 300a may extend... On different surfaces of the sound-absorbing structural component 300, some channels 300a extend to the side of the sound-absorbing structural component 300, and some channels 300a extend to the bottom surface of the sound-absorbing structural component 300. In order to prevent the sound-absorbing particles 400 from falling out of the channels 300a, a sealing structure (such as the breathable barrier layer 500 mentioned later) is provided on the surface of the sound-absorbing structural component 300. The sealing structure is used to seal the openings formed by the channels 300a on the surface of the sound-absorbing structural component 300, so as to confine the sound-absorbing particles 400 within the channels 300a.

[0020] In summary, regardless of whether the sound-absorbing structural component 300 or other sealing structures are used, the sound-absorbing particles 400 are confined within the duct 300a and will not fall out of the duct 300a. Of course, the sound-absorbing structural component 300 can also adopt other shapes.

[0021] In this embodiment, a sound-absorbing structure 300 is added inside the speaker housing 100. The sound-absorbing particles 400 are filled in the channels 300a of the sound-absorbing structure 300. The sound-absorbing structure 300 itself has a sound-absorbing function and also serves as a supporting skeleton for the sound-absorbing particles 400, supporting and limiting the sound-absorbing particles 400. This ensures that the sound-absorbing particles 400 have a certain degree of mobility in the channels 300a, allowing them to flow to different positions in the sound-absorbing structure 300 and then to different positions in the speaker housing 100. At the same time, the walls of the channels 300a limit the sound-absorbing particles 400, preventing excessive mobility of the sound-absorbing particles 400 from causing localized dense or sparse areas.

[0022] Therefore, the sound-absorbing particles 400 are more evenly distributed in the speaker housing 100 by the multiple channels 300a of the sound-absorbing structure 300, which is beneficial to improving the uniformity of the distribution of the sound-absorbing particles 400 and improving the acoustic performance of the speaker module.

[0023] In addition, by filling the interior of the sound-absorbing structure 300 with sound-absorbing particles 400 and installing the sound-absorbing structure 300 inside the speaker housing 100, the sound-absorbing particles 400 can be distributed in various positions of the speaker housing 100. Therefore, the speaker housing 100 does not need to be specially designed with openings to fill in the sound-absorbing particles 400, thus avoiding the additional processing steps caused by openings.

[0024] In an optional embodiment, the sound-absorbing structural component 300 is a foamed structure, which has a closed, dense surface layer and an internal microporous structure. The foamed structure has multiple pores, the pore diameter of which is smaller than the pore diameter of the channel 300a. That is, the pore diameter is smaller, and the pores are mainly used for air permeability, allowing sound waves to pass through; the pore diameter of the channel 300a is larger, and the channel 300a is mainly used to fill the sound-absorbing particles 400.

[0025] It should be noted that the pore diameter can be understood as the diameter of the pore; the pore diameter of channel 300a can be understood as the width of channel 300a. When channel 300a is a circular channel, the pore diameter of channel 300a can be understood as the diameter of the circular channel.

[0026] Optionally, the foamed structure can be sound-absorbing cotton, sponge, foam, etc. The pore size of the sound-absorbing cotton is on the micrometer scale, specifically between tens and hundreds of micrometers.

[0027] In this embodiment, because the foamed structure is made of a relatively porous material with multiple interconnected pores, sound waves can penetrate the sound-absorbing structure 300 through these pores and reach the sound-absorbing particles 400, ensuring good air permeability and sound absorption performance. Furthermore, the foamed structure has a simple manufacturing process and low cost.

[0028] Of course, in other embodiments, the sound-absorbing structure 300 may be made of other breathable structures besides foam structures.

[0029] In an optional embodiment, the sound-absorbing structure 300 is a porous interconnected structure with multiple interconnected channels 300a, each channel 300a being simultaneously connected to multiple channels 300a. The interconnected channels 300a form a mesh-like diffusion structure, which facilitates the rapid flow of sound-absorbing particles 400 through the channels 300a to various locations, and promotes the rapid distribution of sound-absorbing particles 400 across the sound-absorbing structure 300.

[0030] In this embodiment, relying on the porous interconnected structure, only a portion of the channels 300a need to be filled with sound-absorbing particles 400 to allow the particles to flow to each channel 300a, eliminating the need to fill each channel 300a separately. This simplifies the filling process. Furthermore, the interconnectedness of the multiple channels 300a facilitates the distribution of the sound-absorbing particles 400 across the sound-absorbing structural component 300, improving the uniformity of particle distribution.

[0031] Of course, in other embodiments, the sound-absorbing structure 300 may not be a porous interconnected structure, that is, the multiple channels 300a are not interconnected. In this case, it is necessary to fill each channel 300a with sound-absorbing particles 400 separately.

[0032] In an optional embodiment, the multiple channels 300a are arranged in an array. Optionally, the multiple channels 300a can be arranged in a linear array, a square array, a circular array, etc. The embodiments of this application do not limit the array distribution of the channels 300a.

[0033] Further optional, refer to Figure 2 As shown, the plurality of channels 300a includes a first channel and a second channel. The first channel extends along a first direction, and the second channel extends along a second direction. The first direction and the second direction are perpendicular. The plurality of first channels are spaced apart along the second direction, and the plurality of second channels are spaced apart along the first direction. The first direction can be understood as... Figure 2 The first direction is the height direction, and the second direction can be understood as... Figure 2 The horizontal direction.

[0034] In this embodiment, the channels 300a are arranged in an array, indicating that the channels 300a adopt a relatively regular arrangement. Each channel 300a is filled with sound-absorbing particles 400. Therefore, the distribution area of ​​the sound-absorbing particles 400 is also relatively regular and uniform, which is more conducive to improving the distribution uniformity of the sound-absorbing particles 400 and further improving the acoustic performance of the speaker module.

[0035] Of course, in other embodiments, reference Figure 1 As shown, the multiple channels 300a may not be arranged in an array. Specifically, among the multiple channels 300a, some channels 300a extend in a direction parallel to the surface of the sound-absorbing structure 300, while some channels 300a extend in a direction intersecting the surface of the sound-absorbing structure 300. That is, some channels 300a are inclined, and the inclination angles of the different channels 300a are also different.

[0036] In an optional embodiment, refer to Figure 1 and Figure 2 As shown, the sound-absorbing structure 300 includes a first sound-absorbing part 310 and a second sound-absorbing part 320. The first sound-absorbing part 310 is located on the first side of the speaker unit 200, and the second sound-absorbing part 320 is located on the second side of the speaker unit 200. The first side and the second side are opposite sides of the speaker unit 200, respectively. Both the first sound-absorbing part 310 and the second sound-absorbing part 320 are provided with a channel 300a, and the channel 300a is filled with sound-absorbing particles 400. Therefore, sound-absorbing particles 400 are provided on both opposite sides of the speaker unit 200.

[0037] In this embodiment, the first sound-absorbing portion 310 and the second sound-absorbing portion 320 are respectively distributed on opposite sides of the speaker unit 200. The sound-absorbing particles 400 are filled through the channels 300a in these two sound-absorbing portions, so that the sound-absorbing particles 400 are distributed on both sides of the speaker unit 200. Therefore, there is no need to reserve a channel for the sound-absorbing particles 400 to move from one side of the speaker unit 200 to the other side. Therefore, there is no need to make special designs for the speaker housing 100 to reserve a channel. The sound-absorbing structural component 300 acts as a transition component, so that the sound-absorbing particles 400 are directly distributed on both sides of the speaker unit 200, which helps to reduce the design requirements of the speaker housing 100.

[0038] Of course, in other embodiments, the sound-absorbing structure 300 may not include the first sound-absorbing part 310 and the second sound-absorbing part 320 described above. The sound-absorbing structure 300 is disposed in other spaces within the speaker housing 100. The spaces on opposite sides of the speaker unit 200 can be connected by a reserved channel, so that the sound-absorbing particles 400 can reach the other side of the speaker unit 200 from one side space of the speaker unit 200.

[0039] In an optional embodiment, the distance between the surface of the sound-absorbing structure 300 and the inner wall of the speaker housing 100 is less than a preset value, indicating that the distance between the surface of the sound-absorbing structure 300 and the inner wall of the speaker housing 100 is small, and the surface of the sound-absorbing structure 300 is close to the inner wall of the speaker housing 100.

[0040] It should be noted that the preset values ​​can be set as needed.

[0041] Optionally, the sound-absorbing structure 300 is a polyhedral structure, with different surfaces of the sound-absorbing structure 300 being parallel to different inner wall surfaces of the speaker housing 100, and the distance between each surface of the sound-absorbing structure 300 and its corresponding inner wall surface of the speaker housing 100 being less than a preset value.

[0042] Alternatively, the sound-absorbing structure 300 is adapted to the structure of the speaker housing 100, and different surfaces of the sound-absorbing structure 300 contact different inner wall surfaces of the speaker housing 100 respectively.

[0043] In this embodiment, the distance between the surface of the sound-absorbing structural component 300 and the inner wall of the speaker housing 100 is small, indicating that the surface of the sound-absorbing structural component 300 is close to the inner wall of the speaker housing 100. The structure of the sound-absorbing structural component 300 is well-suited to the shape of the speaker housing 100. Therefore, the sound-absorbing structural component 300 fills most of the space inside the speaker housing 100 except for the speaker unit 200, and the sound-absorbing particles 400 also fill most of the space inside the speaker housing 100 except for the speaker unit 200. This is beneficial to further increase the distribution area of ​​the sound-absorbing particles 400, improve the sound absorption effect, and ensure acoustic performance.

[0044] In the alternative solutions of this application, refer to Figure 1 As shown, the surface of the sound-absorbing structure 300 includes a first surface 301 and a second surface 302 connected together. The first surface 301 is opposite to the speaker unit 200, and the second surface 302 is not opposite to the speaker unit 200. The channel 300a extends to the second surface 302. That is, the channel 300a extends to the surface that is not opposite to the speaker unit 200.

[0045] In this embodiment, the duct 300a extends to the surface area of ​​the sound-absorbing structure 300 that is not opposite to the speaker unit 200. Therefore, the opening of the duct 300a on the surface of the sound-absorbing structure 300 will not be opposite to the speaker unit 200, so that the sound-absorbing particles 400 in the duct 300a avoid risky parts such as the metal sheet on the back of the speaker unit 200, and avoid the metal sheet on the back of the speaker unit 200 affecting the sound-absorbing particles 400 during the filling process.

[0046] In an optional embodiment, refer to Figure 1As shown, the sound-absorbing structural member 300 is provided with a clearance groove 300b, which is used to avoid the speaker unit 200. The speaker unit 200 is located inside the clearance groove 300b, and the groove wall surface of the clearance groove 300b serves as the first surface 301, that is, the channel 300a does not extend to the groove wall surface of the clearance groove 300b. The surface of the speaker unit 200 other than the groove wall surface of the clearance groove 300b is the first surface 301.

[0047] Optionally, the clearance groove 300b can be a square groove or a groove of other shapes, as long as it can allow the speaker unit 200 to pass. Further, the clearance groove 300b can be the same shape as the speaker unit 200 to better limit and fix the speaker unit 200.

[0048] In this embodiment, the sound-absorbing structure 300 is further provided with a clearance groove 300b, which is used to accommodate the speaker unit 200, thus providing clearance for the speaker unit 200 and facilitating its stable fixation. Moreover, the sound-absorbing structure 300 does not require deformation to compress and fix the speaker unit 200, thereby avoiding the impact of deformation on the channel 300a and the sound-absorbing particles 400, which helps to ensure stable acoustic performance.

[0049] Of course, in other embodiments, the sound-absorbing structure 300 may not have the clearance groove 300b. The sound-absorbing structure 300 is sound-absorbing cotton, which has certain deformation properties. The sound-absorbing cotton can fix the speaker unit 200 between the sound-absorbing structure 300 and the inner wall of the speaker housing 100 by compression.

[0050] In the alternative solutions of this application, refer to Figure 3 As shown, the speaker module also includes a breathable barrier layer 500, which is disposed on the surface of the sound-absorbing structure 300. The breathable barrier layer 500 closes the openings formed by the channels 300a on the surface of the sound-absorbing structure 300, thereby confining the sound-absorbing particles 400 within the channels 300a. Optionally, the breathable barrier layer 500 may cover the entire surface of the sound-absorbing structure 300, or it may cover a portion of the surface of the sound-absorbing structure 300. The breathable barrier layer 500 may be disposed on the surface of the sound-absorbing structure 300 by adhesive bonding or other means. In short, the breathable barrier layer 500 closes the openings formed by each channel 300a on the surface of the sound-absorbing structure 300, preventing the sound-absorbing particles 400 within the channels 300a from leaking out.

[0051] The breathable barrier layer 500 can be made of non-woven fabric, which has small pores and good air permeability. The breathable barrier layer 500 can also be other barrier layer structures with breathable properties. This application does not limit the specific structure of the breathable barrier layer 500. In summary, the breathable barrier layer 500 has both breathable properties, ensuring acoustic performance, and can block the openings formed by the channels 300a on the surface of the sound-absorbing structure 300, preventing the sound-absorbing particles 400 from leaking out.

[0052] In this embodiment, a breathable barrier layer 500 is added to the loudspeaker. This layer seals the openings of each channel 300a, preventing the sound-absorbing particles 400 from leaking out. This facilitates the stable distribution of the sound-absorbing particles 400 within each channel 300a, and consequently, their stable distribution across the loudspeaker housing 100, thus ensuring the sound absorption performance of the particles 400. Simultaneously, the breathable barrier layer 500 is breathable, allowing sound waves to pass through it and enter the interior of the sound-absorbing structure 300, ensuring successful sound absorption by the particles 400.

[0053] Of course, in other embodiments, the breathable barrier layer 500 can be replaced by a sealing block or other structure. The sealing block directly seals the opening formed by the channel 300a on the surface of the sound-absorbing structure 300, thereby confining the sound-absorbing particles 400 within the channel 300a. The sealing block and the sound-absorbing structure 300 can be connected by means of bonding or other methods.

[0054] When designing the shape of the channel 300a of the sound-absorbing structural component 300, considering that the speaker housing 100 has a relatively irregular structure, such as... Figure 1 The speaker housing 100 structure shown also allows for an irregular design of the channel 300a to improve the porosity of the sound-absorbing structural component 300; for a more regular structure like the speaker housing 100, such as... Figure 2 The speaker housing 100 structure shown can also be designed with a more regular structure, such as the channel 300a arranged in an array.

[0055] For cases where irregular pores 300a need to be designed, a specific foaming mold needs to be designed according to the structure of the sound-absorbing structural component 300. Then, a crossbeam is placed at the position where the pores 300a need to be designed. After foaming is completed in the foaming mold, the crossbeam is removed from the foaming mold to obtain a sound-absorbing structural component 300 with multiple pores 300a.

[0056] For cases requiring regularly shaped channels 300a, a detachable, regularly shaped mesh structure can be placed inside a regularly shaped foaming mold. After foaming, the mesh structure can be disassembled and removed to form a sound-absorbing structural component 300 with multiple channels 300a. Finally, the sound-absorbing structural component 300 is die-cut according to the required shape to fit the internal space shape of the speaker housing 100.

[0057] In this embodiment, the diameter of the sound-absorbing particles 400 is in the range of 0.3mm-0.4mm, and the aperture of the channel 300a needs to be designed according to at least 0.6mm (i.e. the diameter of two sound-absorbing particles 400). For areas with relatively narrow space inside the speaker housing 100, the channel 300a can be reserved according to the aperture range of 0.3mm-0.4mm. At this time, the sound-absorbing structure 300 mainly serves to fix the sound-absorbing particles 400.

[0058] In practical applications, if the number of openings formed by the channel 300a on the surface of the sound-absorbing structure 300 is small, then some openings can be sealed with non-woven fabric, and sound-absorbing particles 400 can be filled into the channel 300a from the other unsealed openings. After filling, the unsealed openings are sealed. If the channel 300a forms openings on multiple surfaces of the sound-absorbing structure 300, and the number of openings is large, then for ease of processing, the openings on multiple surfaces of the sound-absorbing structure 300 are first sealed with non-woven fabric, leaving only one surface opening. Sound-absorbing particles 400 are then filled into the channel 300a from the remaining surface opening. After filling, the unsealed openings are sealed, thus achieving all-round sealing of the channel 300a.

[0059] After the filling and encapsulation processes of the sound-absorbing particles 400 are completed, the sound-absorbing structural component 300 is baked or left to stand to prevent the glue used in the subsequent installation process to the speaker housing 100 from evaporating and entering the sound-absorbing particles 400, thereby preventing the sound-absorbing particles 400 from failing.

[0060] Finally, the sound-absorbing structural component 300 is installed into the speaker housing 100 to complete the installation process.

[0061] Based on the speaker module disclosed in this application, this application also discloses an electronic device, which includes a device housing and the speaker module in the above embodiments, wherein the speaker module is disposed in the device housing.

[0062] Optionally, in addition to the device housing and speaker module, the electronic device may also include functional modules such as battery module and sensors, which are located inside the device housing.

[0063] In this embodiment, the speaker module of the electronic device is equipped with a sound-absorbing structure 300. Multiple channels 300a of the sound-absorbing structure are used to fill the sound-absorbing particles 400, which support and limit the sound-absorbing particles 400. This allows the sound-absorbing particles 400 to be distributed in various positions within the speaker housing 100, resulting in a more uniform distribution of the sound-absorbing particles 400. This improves the uniformity of the distribution of the sound-absorbing particles 400 and thus enhances the acoustic performance of the electronic device.

[0064] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices, video game consoles, etc. This application does not limit the specific types of electronic devices.

[0065] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
