Description

Technical Field

[0001] The present application belongs to the technical field of electronic devices, and specifically relates to an electronic device. Background Art

[0002] With the popularization and promotion of smart devices, users have higher and higher requirements for the functions and experience of mobile phones, and audio experience is one of the important dimensions that users pay attention to. In the related technology, the speaker includes a front cavity steel plate, a support, a waterproof breathable membrane and a speaker unit. The support is supported between the front cavity steel plate and the speaker unit, and the waterproof breathable membrane is arranged on the front cavity steel plate. Limited by the internal space of the mobile phone and due to the existence of the front cavity steel plate of the speaker, the speaker unit needs to be moved backwards. In this way, the volume of the rear cavity area of ​​the speaker is reduced, resulting in poor low-frequency performance of the speaker, which cannot meet the user's usage needs in scenarios such as gaming experience (such as stereo experience), greatly reducing the product's performance and market competitiveness. Utility Model Content

[0003] The present application aims to provide an electronic device that solves the problem of poor low-frequency performance of a speaker.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] An embodiment of the present application proposes an electronic device, comprising: a frame, the frame being provided with a through hole; a speaker, arranged in the frame, the speaker comprising: a shell, the shell being provided with an opening; a speaker unit, arranged in the shell, the speaker unit and the inner surface of the shell enclosing a front cavity and a rear cavity, the opening connecting the front cavity and the through hole; an elastic support member, the first end of the elastic support member is connected to one of the frame and the speaker unit, the second end of the elastic support member passes through the opening and is connected to the other of the frame and the speaker unit, and the elastic support member is used to support the speaker unit.

[0006] In an embodiment of the present application, the electronic device includes a frame and a speaker. The speaker includes a housing, a speaker unit and an elastic support member.

[0007] The frame is provided with a through hole, and the shell is provided with an opening. The speaker unit is arranged in the shell, and the speaker unit and the inner surface of the shell enclose a front cavity and a rear cavity, the front cavity is connected to the opening, and the opening is connected to the through hole. That is, the opening connects the front cavity and the through hole.

[0008] The elastic support is located at the opening of the shell, the first end of the elastic support is connected to one of the frame and the speaker unit, and the second end of the elastic support passes through the opening and is connected to the other of the frame and the speaker unit. In other words, the frame, as a mounting carrier of the elastic support, has the function of limiting and positioning the elastic support, and the elastic support is used to support the speaker unit. It can be seen that the frame replaces the front cavity steel plate of the speaker in the related art, effectively utilizing the existing structure of the frame, so that the frame forms a part of the speaker component.

[0009] It is understandable that the front cavity steel plate in the related art is eliminated, and the elastic support member is supported between the speaker unit and the frame. When the external dimensions of the electronic device remain unchanged, the speaker unit moves toward the through hole relative to the speaker unit in the related art, and the volume of the rear cavity enclosed by the speaker unit and the speaker shell increases accordingly, so that the electroacoustic performance of the speaker will also be improved, which can improve the low-frequency performance of the speaker, and is conducive to improving the product's performance and market competitiveness.

[0010] Similarly, since the speaker unit moves toward the through hole relative to the speaker unit in the related art, it is beneficial to reduce the thickness of the electronic device and realize the lightweight and thin product while the volume of the rear cavity of the speaker remains unchanged.

[0011] It can be understood that, since the frame replaces the front cavity steel plate in the related art, the components of the speaker are reduced, and the material input of the speaker is reduced, which is conducive to reducing the production cost of the product.

[0012] It is understandable that the elastic support member is supported between the speaker unit and the frame, and has the function of supporting and fixing the speaker unit, which can ensure the matching size of the speaker unit and the frame, and can ensure the matching position of the speaker unit, the opening and the through hole, and provides a reliable structural support for the effective operation of the speaker. In addition, the elastic support member is elastic, and when the electronic device falls, the elastic support member can reduce the force acting on the speaker unit and the frame, so as to protect the speaker unit while ensuring the matching size of the speaker unit and the frame, which is conducive to extending the service life of the electronic device.

[0013] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figures 1 to 6 An electronic device 10 provided in an embodiment of the present application is described.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, according to the present application, some electronic devices 10 include: a frame 100, the frame 100 is provided with a through hole 110; a speaker 200, which is arranged in the frame 100, and the speaker 200 includes: a shell 210, and the shell 210 is provided with an opening 212; a speaker unit 220, which is arranged in the shell 210, and the inner surface of the speaker unit 220 and the shell 210 encloses a front cavity 230 and a rear cavity 240, and the opening 212 connects the front cavity 230 and the through hole 110; an elastic support member 260, the first end 262 of the elastic support member is connected to one of the frame 100 and the speaker unit 220, the second end 264 of the elastic support member passes through the opening 212 and is connected to the other of the frame 100 and the speaker unit 220, and the elastic support member 260 is used to support the speaker unit 220.

[0030] In the embodiment of the present application, the electronic device 10 includes a frame 100 and a speaker 200. The speaker 200 includes a housing 210, a speaker unit 220 and an elastic support member 260.

[0031] The frame 100 is provided with a through hole 110, and the housing 210 is provided with an opening 212. The speaker unit 220 is provided in the housing 210, and the inner surface of the speaker unit 220 and the housing 210 encloses a front cavity 230 and a rear cavity 240, the front cavity 230 is connected to the opening 212, and the opening 212 is connected to the through hole 110. That is, the opening 212 is connected to the front cavity 230 and the through hole 110.

[0032] Among them, the elastic support member 260 is located at the opening 212 of the housing 210, the first end 262 of the elastic support member is connected to one of the frame 100 and the speaker unit 220, and the second end 264 of the elastic support member passes through the opening 212 and is connected to the other of the frame 100 and the speaker unit 220. In other words, the frame 100, as a mounting carrier of the elastic support member 260, has the function of limiting and positioning the elastic support member 260, and the elastic support member 260 is used to support the speaker unit 220. It can be seen from this that the frame 100 replaces the front cavity steel plate of the speaker in the related art, effectively utilizes the existing structure of the frame 100, so that the frame 100 forms a part of the component of the speaker 200.

[0033] It is understandable that the front cavity steel plate in the related art is eliminated, and the elastic support member 260 is supported between the speaker unit 220 and the frame 100. When the external dimensions of the electronic device 10 remain unchanged, the speaker unit 220 moves toward the through hole 110 relative to the speaker unit in the related art, and the volume of the rear cavity 240 enclosed by the speaker unit 220 and the housing 210 of the speaker 200 increases accordingly, so that the electroacoustic performance of the speaker 200 will also be improved, which can improve the low-frequency performance of the speaker 200, and is conducive to improving the product's performance and market competitiveness.

[0034] Similarly, since the speaker unit 220 moves toward the through hole 110 relative to the speaker unit 220 in the related art, when the volume of the rear cavity 240 of the speaker 200 remains unchanged, it is beneficial to reduce the thickness of the electronic device 10 and realize the lightweight and thin product.

[0035] It can be understood that, since the frame 100 replaces the front cavity steel plate in the related art, the components of the speaker 200 are reduced, and the material input of the speaker 200 is reduced, which is conducive to reducing the production cost of the product.

[0036] It is understandable that the elastic support member 260 is supported between the speaker unit 220 and the frame 100. The elastic support member 260 has the function of supporting and fixing the speaker unit 220, and can ensure the matching size of the speaker unit 220 and the frame 100, and can ensure the matching position of the speaker unit 220, the opening 212 and the through hole 110, and provides a reliable structural support for the effective operation of the speaker 200. In addition, the elastic support member 260 is elastic. When the electronic device 10 falls, the elastic support member 260 can reduce the force acting on the speaker unit 220 and the frame 100, so as to protect the speaker unit 220 while ensuring the matching size of the speaker unit 220 and the frame 100, which is conducive to extending the service life of the electronic device 10.

[0037] Optionally, along the thickness direction of the electronic device 10 , at least a portion of the rear cavity 240 is located between the speaker unit 220 and the front cavity 230 .

[0038] Optionally, the elastic support member 260 includes a silicone member, foam, etc., which are not listed here one by one.

[0039] Optionally, the electronic device 10 can be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop computer, a mobile computer, an augmented reality device (also known as an AR device), a virtual reality device (also known as a VR device), a handheld game console, etc.

[0040] In some embodiments, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the speaker 200 further includes a waterproof breathable membrane 250 , which is disposed on the frame 100 , and the waterproof breathable membrane 250 covers the through hole 110 .

[0041] In this embodiment, the structure of the speaker 200 is further defined.

[0042] Specifically, the speaker 200 further includes a waterproof breathable membrane 250 .

[0043] The waterproof breathable membrane 250 is disposed on the frame 100 and covers the through hole 110. That is, the frame 100 serves as a mounting carrier for the waterproof breathable membrane 250 and the elastic support member 260 and has the function of limiting and positioning the waterproof breathable membrane 250 and the elastic support member 260.

[0044] The waterproof breathable membrane 250 covers the through hole 110, so that water vapor, dirt, etc. in the environment cannot flow into the electronic device 10 through the through hole 110, and water vapor, dirt, etc. in the environment cannot flow into the speaker 200 through the through hole 110, which can ensure the cleanliness and dryness of the internal environment of the electronic device 10.

[0045] In some embodiments, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the speaker unit 220 has a magnetic member 222, a first sound membrane 224 and a second sound membrane 226. Along the thickness direction perpendicular to the electronic device 10, the magnetic member 222 is located between the first sound membrane 224 and the second sound membrane 226, and one of the first end 262 of the elastic support member and the second end 264 of the elastic support member is connected to the magnetic member 222.

[0046] In this embodiment, the matching structure of the speaker unit 220 and the elastic supporting member 260 is further defined.

[0047] The speaker unit 220 comprises a magnetic member 222 , a first sound membrane 224 and a second sound membrane 226 . In a direction perpendicular to the thickness of the electronic device 10 , the magnetic member 222 is located between the first sound membrane 224 and the second sound membrane 226 .

[0048] The elastic support member 260 has a first end and a second end, and the first end 262 of the elastic support member and the second end 264 of the elastic support member are disposed opposite to each other.

[0049] Specifically, one of the first end 262 of the elastic support member and the second end 264 of the elastic support member is connected to the magnetic member 222. That is, the first end 262 of the elastic support member is connected to the magnetic member 222, or the second end 264 of the elastic support member is connected to the magnetic member 222.

[0050] This configuration can satisfy the use requirement that the elastic support member 260 is supported between the speaker unit 220 and the frame 100 .

[0051] Since the elastic support member 260 is connected to the magnetic member 222, the elastic support member 260 not only ensures the matching size of the speaker unit 220 and the frame 100, but also supports the magnetic member 222 to prevent the magnetic member 222 from falling off. That is, the structure of the elastic support member 260 is reused, and the use function of the elastic support member 260 is enriched.

[0052] It can be understood that the elastic support member 260 is located between the first sound membrane 224 and the second sound membrane 226, and the elastic support member 260 is separately arranged from the first sound membrane 224 and the second sound membrane 226. In this way, it can not only meet the use requirement of the elastic support member 260 to support the speaker unit 220, but also avoid scratching the first sound membrane 224 and the second sound membrane 226.

[0053] In some embodiments, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the speaker 200 further includes: a bonding portion 270 , and one of the magnetic member 222 and the frame body 100 is connected to the first end 262 of the elastic support member through the bonding portion 270 .

[0054] In this embodiment, the speaker 200 further includes a bonding portion 270. The bonding portion 270 is located between the magnetic member 222 and the first end 262 of the elastic support member, and the magnetic member 222 and the first end 262 of the elastic support member are connected through the bonding portion 270. Alternatively, the bonding portion 270 is located between the frame 100 and the first end 262 of the elastic support member, and the frame 100 and the first end 262 of the elastic support member are bonded and connected through the bonding portion 270.

[0055] This arrangement is easy to operate and can not only define the matching structure of the magnetic member 222, the frame 100 and the elastic support member 260, but also has the advantage of a simple assembly process.

[0056] In some embodiments, Figure 2 As shown, a portion of the second end 264 of the elastic support member is raised to form a convex portion 2644 , and the other of the magnetic member 222 and the frame body 100 is in contact with the convex portion 2644 .

[0057] In this embodiment, the structure of the elastic support member 260 is further defined so that a portion of the second end 264 of the elastic support member is raised to form a convex portion 2644, and the convex portion 2644 is used to abut against the magnetic member 222, or the convex portion 2644 is used to abut against the frame 100.

[0058] This configuration can reduce the contact area between the elastic supporting member 260 and the other of the magnetic member 222 and the frame body 100 .

[0059] When the protrusion 2644 abuts against the magnetic part 222, the contact area between the elastic support part 260 and the speaker unit 220 can be reduced. In this way, while ensuring the effectiveness of supporting the speaker unit 220, scratches on the first sound membrane 224 and the second sound membrane 226 of the speaker unit 220 are avoided, thereby reducing the probability of damage to the speaker unit 220, which is beneficial to ensuring the performance of the speaker 200.

[0060] When the protrusion 2644 contacts the frame 100, the contact area between the elastic support member 260 and the frame 100 can be reduced, thus avoiding interference between the elastic support member 260 and other structures of the frame 100. The matching dimensions of the speaker unit 220 and the frame 100 can be ensured.

[0061] It can be understood that, specifically, one of the magnetic member 222 and the frame 100 is connected to the first end 262 of the elastic support member, and the other of the magnetic member 222 and the frame 100 is in contact with the second end 264 of the elastic support member. That is, the magnetic member 222 is connected to the first end 262 of the elastic support member, and the frame 100 is in contact with the second end 264 of the elastic support member. Alternatively, the frame 100 is connected to the first end 262 of the elastic support member, and the magnetic member 222 is in contact with the second end 264 of the elastic support member.

[0062] This arrangement can not only meet the use requirement of the elastic support member 260 supporting between the speaker unit 220 and the frame 100, but also simplify the difficulty of disassembling and assembling the electronic device 10, which is beneficial to reducing the processing accuracy requirements of the electronic device 10 and reducing the production cost of the electronic device 10.

[0063] In some embodiments, when the magnetic member 222 is connected to the first end 262 of the elastic support member, the second end 264 of the elastic support member abuts against the frame 100 through the waterproof breathable membrane 250 .

[0064] In this embodiment, the matching structure of the magnetic member 222 and the elastic supporting member 260 is further defined.

[0065] like Figure 3 As shown, when the magnetic member 222 is connected to the first end 262 of the elastic support member, the second end 264 of the elastic support member abuts against the frame 100 through the waterproof breathable membrane 250. That is, the waterproof breathable membrane 250 is located between the second end 264 of the elastic support member and the frame 100. In this way, the through hole 110 of the frame 100 does not need to be avoided, and the value of the width L1 of the through hole 110 can be ensured not to be reduced, which is conducive to improving the electroacoustic performance of the product.

[0066] In some embodiments, when the magnetic member 222 is connected to the first end 262 of the elastic support member, the second end 264 of the elastic support member is located on one side of the waterproof breathable membrane 250 along a direction perpendicular to the thickness of the electronic device 10 .

[0067] In this embodiment, the matching structure of the magnetic member 222 , the elastic supporting member 260 and the frame body 100 is further defined.

[0068] like Figure 6 As shown, when the magnetic member 222 is connected to the first end 262 of the elastic support member, the second end 264 of the elastic support member is located on one side of the waterproof breathable membrane 250 in a direction perpendicular to the thickness of the electronic device 10. That is, the waterproof breathable membrane 250 can avoid the second end 264 of the elastic support member.

[0069] In some embodiments, Figure 5 and Figure 6 As shown, when the frame 100 is connected to the first end 262 of the elastic support member, the first end 262 of the elastic support member is located on one side of the waterproof breathable membrane 250 along a direction perpendicular to the thickness of the electronic device 10 .

[0070] In this embodiment, the matching structure of the magnetic member 222 , the elastic supporting member 260 and the frame body 100 is further defined.

[0071] When the frame 100 is connected to the first end 262 of the elastic support member, the first end 262 of the elastic support member is located on one side of the waterproof breathable membrane 250 in a direction perpendicular to the thickness of the electronic device 10. That is, the waterproof breathable membrane 250 can avoid the first end 262 of the elastic support member. This avoids the waterproof breathable membrane 250 from being blocked due to adhesion with the elastic support member 260. The performance of the electronic device 10 can be guaranteed.

[0072] Optionally, the waterproof breathable membrane 250 is provided with an avoidance gap, and the avoidance gap is used to avoid the first end 262 of the elastic support member.

[0073] Optionally, the waterproof breathable membrane 250 is provided with an avoidance hole, and the avoidance hole is used to avoid the first end 262 of the elastic supporting member.

[0074] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, when the frame 100 is connected to the first end 262 of the elastic support member, the frame 100 is provided with a positioning protrusion 120 , and the positioning protrusion 120 is used to limit the elastic support member 260 .

[0075] In this embodiment, the matching structure of the frame 100 and the elastic supporting member 260 is further defined.

[0076] When the frame 100 is connected to the first end 262 of the elastic support member, the frame 100 is provided with a positioning protrusion 120, which has the function of indicating the assembly position of the elastic support member 260. The elastic support member 260 only needs to be assembled at the positioning protrusion 120 to ensure the matching structure of the elastic support member 260, the waterproof breathable membrane 250 and the through hole 110. The positioning protrusion 120 can simplify the difficulty of assembling the elastic support member 260, which is conducive to improving the disassembly and assembly efficiency of the product.

[0077] In some embodiments, the positioning protrusion 120 is located on the circumferential side of the elastic support member 260 , and the positioning protrusion 120 is an arc-shaped protrusion 2644 extending along the circumference of the elastic support member 260 .

[0078] In this embodiment, the matching structure of the frame 100 and the elastic supporting member 260 is further defined.

[0079] Specifically, the positioning protrusion 120 is located on the circumferential side of the elastic support member 260, and the positioning protrusion 120 is an arc-shaped protrusion 2644 extending along the circumference of the elastic support member 260. This arrangement increases the matching area and matching angle between the positioning protrusion 120 and the elastic support member 260, and can ensure the accuracy of the assembly position of the elastic support member 260.

[0080] In some other embodiments, there are multiple positioning protrusions 120 , and the multiple positioning protrusions 120 are arranged at intervals along the circumference of the elastic support member 260 .

[0081] In some embodiments, Figure 2 and Figure 5 As shown, the electronic device 10 further includes: a sealing member 300 , which is located between the housing 210 and the frame 100 , and is used to seal the connection between the housing 210 and the frame 100 .

[0082] In this embodiment, the structure of the electronic device 10 is further limited, so that the electronic device 10 further includes a seal 300, the seal 300 is located between the housing 210 and the frame 100, and the seal 300 is used to seal the connection between the housing 210 and the frame 100. The seal 300 has a waterproof effect, and prevents water vapor, dirt, etc. from entering the inside of the speaker 200 through the connection between the housing 210 and the frame 100, which is conducive to ensuring the performance of the speaker 200.

[0083] The speaker 200 of the present application eliminates the front cavity steel plate in the related art, and supports the magnet (i.e., magnetic member 222) on the frame 100 through a silicone member (i.e., elastic support member 260). This arrangement can reduce the impact of the front cavity steel plate on the electroacoustic performance and the thickness of the entire machine.

[0084] After the front cavity steel plate in the related art is eliminated, the present application supports the speaker unit 220 by using the silicone member in conjunction with the frame 100 to support the speaker unit 220. In this way, the speaker unit 220 can be moved downward, the volume of the rear cavity 240 of the speaker 200 will increase, and the electroacoustic performance will also be improved. At the same time, the powder filling space is increased, and the product performance is feasible to be further improved.

[0085] The present application ensures that the magnet of the speaker unit 220 will not fall off when the speaker unit 220 is in working state, and at the same time, improves the electroacoustic performance of the product and ensures the thickness of the whole device.

[0086] Alternatively, if Figure 2 and Figure 3 As shown, the elastic support member 260 is attached to the speaker unit 220 , and the speaker unit 220 is supported on the frame 100 by the elastic support member 260 .

[0087] Alternatively, if Figure 5 and Figure 6 As shown, the elastic support member 260 is attached to the frame 100 , and a positioning protrusion 120 may be designed on the frame 100 . After the speaker unit 220 is assembled, it contacts the elastic support member 260 to achieve a supporting effect.

[0088] Alternatively, if Figures 1 to 3 As shown, the electronic device 10 includes a frame 100 (a waterproof breathable membrane 250 is attached to the frame 100 through an adhesive layer 400), an upper shell 214, a lower shell 216 (the lower shell 216 is a plastic shell, and the lower shell 216 is not provided with a front cavity steel plate), a speaker unit 220, a silicone member (i.e., an elastic support member 260) and a waterproof silicone member (i.e., a sealing member 300), etc. The housing 210 of the speaker 200 includes an upper shell 214 and a lower shell 216. Compared with the lower shell 216 in the related art, this arrangement lacks a front cavity steel plate. The silicone member is located directly below the speaker unit 220, with the purpose of contacting with the frame 100 to achieve the purpose of supporting the magnet of the speaker unit 220.

[0089] The silicone member of the present application is attached to the speaker unit 220. Since the front cavity steel plate in the related art is eliminated, the waterproof breathable membrane 250 is transferred and attached to the frame 100. After the front cavity steel plate is eliminated, the silicone member is attached to the speaker unit 220, and the silicone member is attached to the magnet of the speaker unit 220 through the adhesive portion 270.

[0090] The process of assembling the electronic device 10 is as follows: first, fix the speaker unit 220 to the lower shell 216 by dispensing glue; then fix the lower shell 216 and the upper shell 214 together by ultrasonic welding; then stick the elastic support member 260 to the magnet of the speaker unit 220 by means of back glue (i.e., the adhesive portion 270); finally, fasten the speaker unit 220 to the frame 100 by screws.

[0091] like Figure 2 and Figure 3 As shown, after the front cavity steel plate is removed from the lower shell 216, the waterproof breathable membrane 250 is fixed to the frame 100 by means of adhesive, and the middle magnet contacts the frame 100 through the elastic support 260 to achieve the supporting effect. Since the front cavity steel plate is removed, the speaker unit 220 can move downward, that is, the distance relative to the upper shell 214 increases, and the height H of the rear cavity 240 increases. The increase in the height H of the rear cavity 240 can directly bring about the improvement of the electroacoustic performance.

[0092] The elastic support member 260 can directly rest on the waterproof breathable membrane 250 of the frame 100 , and the through hole 110 of the frame 100 does not need to be avoided, ensuring that the width L1 value of the through hole 110 is not reduced, which is beneficial to improving the electroacoustic performance.

[0093] Alternatively, if Figures 4 to 6 As shown, the electronic device 10 includes a frame 100 (a waterproof breathable membrane 250 and an elastic support member 260 are attached to the frame 100), an upper shell 214, a lower shell 216 (the lower shell 216 is a plastic shell, and the lower shell 216 is not provided with a front cavity steel plate), a speaker unit 220, and a waterproof silicone member (i.e., a sealing member 300), etc. Since the front cavity steel plate is eliminated, the waterproof breathable membrane 250 is attached to the frame 100. The supporting silicone member (i.e., the elastic support member 260) is attached to the frame 100, and the frame 100 needs to add a positioning protrusion 120 to locate the position of the supporting silicone member, and the through hole 110 is also located below the waterproof breathable membrane 250.

[0094] The process of assembling the electronic device 10 is as follows: first, fix the speaker unit 220 to the lower shell 216 by dispensing glue; then fix the lower shell 216 and the upper shell 214 together by ultrasonic welding; then, stick the supporting silicone and the waterproof breathable membrane 250 to the corresponding positions of the frame 100 by backing glue; finally, fasten the speaker unit 220 to the frame 100 by screws.

[0095] After the front cavity steel plate is removed from the lower shell 216, the waterproof breathable membrane 250 is fixed to the frame 100 by means of adhesive. At the same time, the supporting silica gel is also fixed to the corresponding position of the frame 100 by means of adhesive with the help of the positioning protrusion 120, and the magnet of the speaker unit 220 contacts the frame 100 through the supporting silica gel to achieve the supporting effect. Since the front cavity steel plate is removed, the speaker unit 220 can move downward, the height H of the rear cavity 240 increases, and the electroacoustic performance can be improved accordingly.

[0096] like Figures 4 to 6 As shown, the attachment of the supporting silicone is relatively easy, and no clamp is required. It is only necessary to design a positioning protrusion 120 on the frame 100, and the risk of scratching the sound membrane of the speaker unit 220 is relatively low.

[0097] The present application eliminates the front cavity steel plate and supports the magnet of the speaker unit 220 on the frame 100 through supporting silicone, thereby reducing the influence of the front cavity steel plate on the electroacoustic performance and the thickness of the whole machine.

[0098] After the front cavity steel plate is removed, the speaker unit 220 can be supported by supporting silica gel and the frame 100, so that the speaker unit 220 can be moved downward, the volume of the rear cavity 240 can be increased, and the electroacoustic low-frequency performance can be improved.

[0099] At the same time, in some projects where the thickness of the whole machine is a bottleneck, the electroacoustic performance needs to be further improved. In addition to increasing the thickness of the whole machine, powder filling can also be considered. The increase in the height of the rear cavity 240 means an increase in the powder filling space, which makes it feasible to further improve the performance of the speaker 200. In this way, while ensuring the thickness of the whole machine, the electroacoustic performance is also improved, which is more conducive to improving the user experience.

[0100] In summary, the front cavity steel plate can not only improve the electroacoustic performance, but also choose powder filling to further improve the electroacoustic performance (the prerequisite for powder filling is that a certain Z-direction height space is required), rather than improving the electroacoustic performance by increasing the thickness of the whole machine. Therefore, both the electroacoustic performance and the thickness of the whole machine can improve the user experience.
