Abstract
Description
Speaker modules and electronic equipment
[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 5, 2023, with application number: 202311656786.8 and application name: "Speaker Module and Electronic Device", all contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the technical field of loudspeakers, and in particular to a loudspeaker module and an electronic device. Background Art
[0003] As the wearing scenarios of wearable electronic devices become more diverse, the requirements for their waterproofness are becoming increasingly stringent. For example, watches require a higher level of waterproofness for daily wear, as well as for use in water-related scenarios such as bathing and diving. Speaker waterproofing is an important part of this. The speaker's sound cavity needs to be connected to the outside of the electronic device to ensure sound quality, so a sound guide channel is usually opened in the housing of the electronic device to ensure the quality of sound transmission. However, in water-related scenarios, water often flows into the electronic device through the sound guide channel, causing damage to the internal parts of the electronic device.
[0004] The speaker is installed in the housing of an electronic device and includes components such as a fixed bracket, a vibrating member, a cover, and a driving assembly. The vibrating member is fixed to the fixed bracket, and the driving assembly drives the vibrating member to vibrate and produce sound. The cover is used to clamp the vibrating member to the fixed bracket, and the cover can enhance the structural strength of the connection between the vibrating member and the fixed bracket. In traditional electronic devices, speaker waterproofing includes two key waterproof interfaces (key waterproof interfaces refer to interfaces where there is a gap between components and water may enter). The first key waterproof interface is located between the speaker and the housing of the electronic device, such as between the housing of the electronic device and the fixed bracket of the speaker. The second key waterproof interface is located inside the speaker, such as between the fixed bracket and the cover. In the prior art, in order to prevent water from entering the interior of the electronic device, a rubber ring is provided between the housing of the electronic device and the fixed bracket to fill the gap between the two. The waterproofing of the interior of the speaker is achieved by bonding the various components. However, the waterproof performance of the rubber ring is limited and it is easy to shift or fall off under the impact of large water flow. There is still a risk of water entering between the housing of the electronic device and the speaker. It can be seen that its reliability is low and its waterproof performance is poor.
[0005] Therefore, the waterproof structure of the speaker of the electronic device in the prior art has low reliability and poor waterproof performance.
[0006] Summary of the Invention
[0007] The speaker module and electronic device provided in the embodiments of the present application solve the problems of low reliability and poor waterproof performance of the speaker waterproof structure of electronic devices in the prior art.
[0008] An embodiment of the present application provides a speaker module, including a structural shell and a speaker installed in the structural shell, wherein the speaker includes a vibrating member and an annular structure.
[0009] The annular structure is connected to the first part of the structural shell, and the annular structure and the first part are configured as an integrated structure, and the outer peripheral edge of the vibration component is sealed and connected to the annular structure.
[0010] The speaker module provided in the embodiment of the present application includes an annular structure, which is connected to the first part of the structural shell and is configured as an integrated structure with the first part of the structural shell, so that there is no gap between the annular structure and the first part of the structural shell. In a wading scenario, water cannot enter the electronic device through the path between the structural shell and the cover.
[0011] Or it can be understood that the annular structure is regarded as the outer shell of the speaker. For example, a part of the fixing bracket or cover of the speaker can be set as an annular structure. The annular structure and the first part of the structural shell are designed as an integrated structure, that is, the outer shell of the speaker and at least the first part of the structural shell are designed as an integrated structure, thereby eliminating the key waterproof interface between the speaker and the structural shell. Using the structural shell as a part of the shell of the electronic device eliminates the key waterproof interface between the shell of the electronic device and the speaker, thereby reducing the risk of water ingress to the electronic device. In addition, the annular structure and the structural shell do not rely on external waterproof components such as rubber rings to achieve waterproofing, but directly eliminate the gap between the components, so that they can withstand stronger water flow impact, have higher reliability, and have stronger waterproof performance.
[0012] Therefore, the speaker module waterproof structure provided in the embodiment of the present application has high reliability and good waterproof performance.
[0013] In some embodiments, the speaker further comprises a fixing bracket and a cover body disposed on both sides of the vibrating element, wherein the cover body comprises an annular structure, or the fixing bracket comprises an annular structure.
[0014] With this solution, the mounting bracket, vibrator, and cover are stacked sequentially along the thickness of the speaker. The mounting bracket is the speaker's skeletal structure, supporting, securing, and protecting its components, while the cover clamps the vibrator to the mounting bracket, ensuring a secure fit.
[0015] In some embodiments, the annular structure is connected to the first portion of the structural shell along its circumference, and there is no gap between the annular structure and the structural shell along its circumference, completely eliminating the waterproof interface between the structural shell and the speaker, thereby achieving optimal waterproof performance.
[0016] In some embodiments, the first portion of the structural shell is provided with a receiving groove, and the annular structure protrudes from the first portion of the structural shell toward the inner side of the receiving groove. The speaker is located in the receiving groove of the structural shell, and the groove wall of the receiving groove is connected to the annular structure to form an integrated structure.
[0017] In some embodiments, the vibrating member includes a diaphragm, and the outer peripheral edge of the vibrating member is sealed and connected to the annular structure. Specifically, the outer peripheral edge of the diaphragm is sealed and connected to the surface of the annular structure facing each other.
[0018] This solution seals the outer edge of the diaphragm to the annular structure, effectively sealing it off from the annular structure. This prevents water from entering the speaker through the annular structure and the diaphragm, as well as the speaker's interior. The structural shell, annular structure, and diaphragm are joined together in a plane perpendicular to the speaker's thickness, sealing the entire housing and effectively preventing water from entering the electronic device.
[0019] In some embodiments, the outer periphery of the diaphragm is sealed to the annular structure using waterproof glue or injection molding. Injection molding can minimize the gap between the diaphragm and the annular structure, improve the sealing and bonding strength between the diaphragm and the annular structure, and provide better waterproof performance.
[0020] In some embodiments, the entire structural shell and the annular structure are configured as an integrated structure to simplify the production process.
[0021] In some embodiments, the structural shell includes a shell body and a sound-emitting structure, wherein the sound-emitting structure is fixedly and detachably connected to the shell body, and the sound-emitting structure has a sound guide channel that connects the sound cavity of the speaker to the exterior of the structural shell. The shell body includes a first portion.
[0022] By adopting the above solution, the part of the structural shell where the sound guide channel is provided is set as a detachable independent component, and the sound-emitting structure can be disassembled to facilitate cleaning of the sound guide channel and reduce the maintenance cost of the electronic equipment.
[0023] In some embodiments, the sound emitting structure and the speaker are arranged facing each other.
[0024] In some embodiments, the sound-emitting structure is detachably connected to the shell body by any one or more of snapping, bonding, and magnetic attraction.
[0025] In some embodiments, the speaker module further includes a dustproof net, which is disposed on the sound-emitting structure and between the sound-emitting structure and the speaker.
[0026] The dust screen prevents debris from entering the speaker module's sound cavity, effectively blocking foreign matter and dust in water-related scenarios, making it highly practical. Furthermore, the dust screen is located between the sound-emitting structure and the vibrating element, making it easy to clean and replace the dust screen after removing the sound-emitting structure.
[0027] An embodiment of the present application further provides an electronic device, wherein the structural shell of the speaker module constitutes at least a portion of the housing of the electronic device.
[0028] The electronic device provided in the embodiment of the present application uses the structural shell of the speaker module as part or all of the electronic device housing. That is, at least a part of the housing of the electronic device and the annular structure of the speaker are configured as an integrated structure, and the waterproof structure has high reliability and good waterproof performance.
[0029] In some embodiments, the electronic device's housing includes a middle frame and a back cover, with the speaker module's structural housing forming the middle frame or back cover. Using the speaker module's structural housing directly as the middle frame or back cover simplifies the overall structure and manufacturing process, and eliminates the need for an additional waterproof structure between the structural housing and the overall housing, resulting in higher waterproof reliability for the entire device.
[0030] In some embodiments, when the speaker module includes a sound-emitting structure, the surface of the sound-emitting structure away from the speaker comprises: a portion of the outer surface of the middle frame or a portion of the outer surface of the back cover. The sound-emitting structure is exposed outside the middle frame or the back cover to facilitate removal of the sound-emitting structure.
[0031] In some embodiments, the electronic device is a watch or a bracelet. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.
[0084] As the wearing scenarios of wearable electronic devices become more diverse, the requirements for their waterproofness are becoming increasingly stringent. For example, watches require a higher level of waterproofness for daily wear, as well as for use in water-related scenarios such as bathing and diving. Speaker waterproofing is an important part of this. The speaker's sound cavity needs to be connected to the outside of the electronic device to ensure sound quality, so a sound guide channel is usually opened in the housing of the electronic device to ensure the quality of sound transmission. However, in water-related scenarios, water often flows into the electronic device through the sound guide channel, causing damage to the internal parts of the electronic device.
[0085] Please refer to FIG1 , which is a schematic structural diagram of an electronic device.
[0086] As shown in Figure 1, the electronic device 200' includes a screen 2' and a shell 3', and the speaker 100' is installed in the shell 3' of the electronic device 200' and is located in the installation cavity formed by the screen 2' and the shell 3'. The shell 3' includes a middle frame 31' and a back cover 32', and the speaker 100' is installed on the back cover 32'. The speaker 100' includes a fixed bracket 11', a vibrator 12' and a cover 13', and also includes components such as a driving assembly (not shown in the figure). The vibrator 12' is fixed on the fixed bracket 11', and the driving assembly drives the vibrator 12' to vibrate and make sound, while the cover 13' is used to clamp the vibrator 12' on the fixed bracket 11' and enhance the structural strength of the position where the vibrator 12' and the fixed bracket 11' are connected. Furthermore, a sound guide channel 321' is provided on the back cover 32'. The sound guide channel 321' connects the sound cavity of the speaker 100' with the outside of the electronic device 200', ensuring that the sound emitted by the speaker 100' is smoothly transmitted out of the electronic device 200'. In a water-related scenario, water will also flow into the electronic device 200' through the sound guide channel 321'.
[0087] As shown in Figure 1, the waterproof structure of the speaker 100' of the electronic device 200' includes two key waterproof interfaces (key waterproof interfaces refer to interfaces where there are gaps between components and water may enter). The first key waterproof interface is located between the fixing bracket 11' of the speaker 100' and the back cover 32' of the electronic device 200'. The second key waterproof interface is located inside the speaker 100', that is, between the fixing bracket 11' and the cover 13'. In order to prevent water from entering the interior of the electronic device 200' and damaging other electronic components, a rubber ring 4' is provided between the back cover 32' of the electronic device 200' and the fixing bracket 11' to fill the gap between the two. The waterproofing inside the speaker 100' is achieved by bonding the various components together. For example, a waterproof adhesive layer is provided between the vibrating element 12' and the fixing bracket 11' or the cover 13' to achieve a sealed connection and block the water inlet path between the fixing bracket 11' and the cover 13'. However, the waterproof performance of the rubber ring 4' is limited and it is easy to shift or fall off under the impact of a large water flow. There is still a risk of water entering between the housing 3' of the electronic device 200' and the speaker 100'. It can be seen that its reliability is low and its waterproof performance is poor.
[0088] Therefore, the waterproof structure of the speaker of the electronic device in the prior art has low reliability and poor waterproof performance.
[0089] To address the above issues, embodiments of the present application provide a speaker module and electronic device. Through structural improvements, these devices reduce critical waterproof interfaces, mitigate the risk of water ingress, and enhance the reliability of the speaker's waterproof structure. The following describes the basic structure of the electronic device provided by embodiments of the present application, in conjunction with the accompanying drawings, to better illustrate the application scenarios of the speaker module provided by embodiments of the present application.
[0090] The electronic devices provided in this application include but are not limited to wearable electronic devices such as smart watches, bracelets, headphones, glasses, or terminals with audio output functions such as mobile phones, tablets, speakers, and televisions. The following is an illustrative description of the structure of the electronic device using a smart watch as an example.
[0091] Please refer to Figures 2 to 5. Figures 2-3 are schematic diagrams of the three-dimensional structure of the electronic device according to the embodiment of the present application; Figure 4 is a schematic diagram of the assembly structure of the speaker and the shell in the electronic device according to the embodiment of the present application; and Figure 5 is a schematic diagram of the principle structure of the electronic device according to the embodiment of the present application.
[0092] As shown in Figures 2 to 5, the electronic device 200 includes a housing 7, a screen 6 and a speaker 1. The screen 6 is mounted on the housing 7. The screen 6 and the housing 7 surround and form a mounting cavity 70, and the speaker 1 is located in the mounting cavity 70. The screen 6 can be used to display images, and the user can perform human-computer interaction through the screen 6. It should be noted that the screen 6 can be a liquid crystal display (LCD), an organic light emitting diode (OLEO) display, etc., and this application does not limit this. The housing 7 is used to support the display screen, as well as to accommodate and install the speaker 1 and other various electronic components of the electronic device 200. Other electronic components may include circuit boards, batteries, cameras, etc., and this application does not limit this.
[0093] It should be noted that Figures 2 to 5 illustrate the dial of the smart watch, that is, the main functional part of the smart watch. In addition to the dial, the electronic device 200 may also include wearable components such as a strap to facilitate wearing by the user, and this application does not limit this. It will be understood by those skilled in the art that in the scenarios illustrated in Figures 2 to 5, the dial is circular as a whole, that is, the projection of the screen 6 and the housing 7 in a plane perpendicular to the thickness direction Y of the electronic device is circular. In other alternative embodiments, the dial as a whole may also be rectangular, square, oval, etc., and this application does not limit this.
[0094] Those skilled in the art will appreciate that the specific structure of the shell 7 is not limited. In one embodiment, the shell 7 includes a middle frame 71 and a back cover 72, wherein, exemplarily, the middle frame 71 is a frame structure, and the back cover 72 can be a battery cover of the electronic device 200. The back cover 72 and the screen 6 are respectively arranged on both sides of the middle frame 71 along the thickness direction Y of the electronic device, so that the screen 6, the middle frame 71 and the back cover 72 are together surrounded to form an installation cavity 70.
[0095] Among them, the middle frame 71 provides support and protection for the electronic device 200 as a whole, and its material can be stainless steel, ceramic, titanium alloy, and other hard materials, which is not limited in this application. The back cover 72 covers the lower end of the middle frame 71 and contacts the user's wrist when worn. Optionally, the back cover 72 can be a stainless steel back cover, a titanium alloy back cover, etc., which is not limited in this application. Optionally, the back cover 72 can be covered on the middle frame 71 by screwing, snapping, etc., and a waterproof structure such as a sealing ring can be provided between the back cover 72 and the middle frame 71 to improve the waterproof sealing performance of the electronic device 200. In some embodiments, the back cover 72 and the middle frame 71 can also be set as an integrated structure to further enhance the waterproof effect of the entire electronic device 200, which is not limited in this application.
[0096] It should be noted that the speaker 1 can be installed on either the back cover 72 or the middle frame 71 (for example, the scenario shown in Figures 14a to 15, which will be further expanded upon later). This application does not limit this. When the speaker 1 is installed on the back cover 72, the speaker 1 and the back cover 72 can form a speaker module 100. When the speaker 1 is installed on the middle frame 71, the speaker 1 and the middle frame 71 can form a speaker module 100.
[0097] As shown in Figures 3 to 5, in one embodiment, the speaker 1 is installed on the back cover of the electronic device. Accordingly, a sound guide channel is provided on the back cover. The sound guide channel connects the sound cavity in the speaker with the outside of the electronic device, so that the sound emitted by the speaker can be better transmitted out of the electronic device, avoiding the sound emitted by the vibrating part from being blocked by structural parts on the path of propagation to the outside of the electronic device, which is beneficial to improving the quality and loudness of the audio of the electronic device.
[0098] Among them, the number of sound guide channels is not limited, and there can be 1, 2, 3, 4, etc., and only a few are drawn in the figure for illustration. It is understandable that when the electronic device is a smart watch, the installation position of the speaker and the position of the sound guide channel on the back cover are not limited. For example, when the user wears a smart watch, the sound guide channel can be located on the inside of the user's wrist (9 o'clock direction), the outside of the wrist (3 o'clock direction), the upper side of the wrist (12 o'clock direction) or the lower side of the wrist (6 o'clock direction), etc. The drawings in this application do not make a clear distinction between them.
[0099] It can be understood that the sound guide channel 23 serves as a channel connecting the sound cavity of the speaker 1 and the outside of the electronic device 200. When the user wears the smart watch in water-related scenarios such as bathing and swimming, the sound guide channel 23 will also form a water inlet channel, and water can easily enter the interior of the electronic device 200 from the sound guide channel 23. The present application improves the waterproof structure of the speaker 1 based on this water inlet path. The structure of the speaker module 100 is explained below with reference to the accompanying drawings.
[0100] Please refer to Figures 6-7. Figure 6 is a schematic diagram of the principle structure of the first embodiment of the speaker module of the embodiment of the present application; Figure 7 is a schematic diagram of the principle structure of the second embodiment of the speaker module of the embodiment of the present application.
[0101] As shown in Figures 5 to 7, the speaker module 100 includes a structural shell 2 and a speaker 1 mounted on the structural shell 2. The speaker 1 is a sound-generating device, and the structural shell 2 is used to install and fix the speaker 1 in the electronic device 200.
[0102] It will be understood by those skilled in the art that the structural shell can be formed in the shell 7 of the electronic device 200 as part or all of the shell 7 of the electronic device 200. For example, the entire or a part of the middle frame 71 of the electronic device 200 can be used as the structural shell 2, so that the entire or a part of the middle frame 71 and the speaker 1 together constitute the speaker module 100. Alternatively, the entire or a part of the back cover 72 of the electronic device 200 can be used as the structural shell 2, so that the entire or a part of the back cover 72 and the speaker 1 together constitute the speaker module 100. Alternatively, the middle frame 71 and the back cover 72 of the electronic device 200 can be designed as an integrated structure. In this case, the entire or a part of the entire shell 7 of the electronic device 200 can be used as the structural shell 2, so that the entire or a part of the shell 7 and the speaker 1 together constitute the speaker module 100. This application is not limited to this. Several situations will be further explained later, which will not be expanded here.
[0103] Those skilled in the art will appreciate that the structure of the speaker 1 is not limited. In one embodiment, the speaker 1 includes a vibrating member 12, and fixed brackets 11 and a cover 13 disposed on either side of the vibrating member 12. Alternatively, the fixed brackets 11, vibrating member 12, and cover 13 are stacked in sequence along the thickness direction X of the speaker.
[0104] The fixing bracket 11 is the skeleton structure of the speaker 1, used to support, fix and protect the various components of the speaker 1, while the cover 13 clamps the vibrator 12 to the fixing bracket 11, improving the secure installation of the vibrator 12. The specific shape and structure of the fixing bracket 11 and the cover 13 are not limited in this application, and will be described in detail below with reference to several scenarios.
[0105] Among them, the vibrating member 12 is the main sound-producing device of the loudspeaker 1. The loudspeaker 1 is also provided with a driving assembly. Specifically, the driving assembly may include a voice coil 14 (refer to Figure 8a) and a magnetic circuit assembly 15 (refer to Figure 8a). Among them, the magnetic circuit assembly 15 can be composed of an electromagnet or a permanent magnet and form a stable magnetic field. The voice coil 14 can be configured as an electromagnet wound with a coil. The voice coil 14 is located in the magnetic field formed by the magnetic circuit assembly 15. When the electrical signal of the sound passes through the coil in the voice coil 14, the voice coil 14 can form a magnetic field that repel or attract the magnetic circuit assembly 15, thereby vibrating in the magnetic field formed by the magnetic circuit assembly 15 to convert the electrical signal into a sound signal. The voice coil 14 drives the vibrating member 12 to vibrate and produce sound. The vibration direction of the vibrating member 12 is the thickness direction X of the loudspeaker. It will be understood by those skilled in the art that the structure of the vibrating member 12 is not limited. In one embodiment, the vibrating member 12 includes a diaphragm 121. The diaphragm 121 is a thin film structure, with its outer periphery mounted between the fixed bracket 11 and the cover 13, while its central portion vibrates driven by the voice coil 14. In some embodiments, the vibrating element 12 may further include a dome, which is fixed to the diaphragm 121 and vibrates along with it. The dome can be understood as a mass that increases the weight of the vibrating element 12 and adjusts the frequency of the sound emitted by the vibrating element 12.
[0106] As shown in Figures 5 to 7, the loudspeaker 1 also includes an annular structure 10, which is connected to the first part of the structural shell 2, and the annular structure 10 and the first part are configured as an integral structure, and the outer peripheral edge of the vibration member 12 is sealed and connected to the annular structure 10. The first part is a part of the structural shell 2 that is connected to the annular structure 10, which can be the entirety or a part of the structural shell 2, and the present application does not limit this. In one embodiment, the structural shell 2 as a whole is the first part, that is, the structural shell 2 as a whole is connected to the annular structure 10. In an alternative embodiment, the structural shell 2 is configured as a split structure, for example, it can include an outer shell and an inner shell that are nested, and part or the entirety of the inner shell is the first part of the structural shell 2, and only the inner shell is connected to the annular structure 10. The specific shape of the annular structure 10 is not limited, and can be a circular ring, an elliptical ring, a rectangular ring, etc., and the present application does not limit this.
[0107] The speaker module 100 provided in the embodiment of the present application, the speaker 1 includes an annular structure 10, the annular structure 10 is connected to the first part of the structural shell 2, and is configured as an integrated structure with the first part of the structural shell 2, so that there is no gap between the annular structure 10 and the first part of the structural shell 2. In a wading scenario, water cannot enter the electronic device 200 through the path between the structural shell 2 and the cover 13.
[0108] Or it can be understood that the annular structure 10 is regarded as the outer shell of the speaker 1. For example, a part of the fixing bracket 11 or the cover 13 of the speaker 1 can be set as the annular structure 10. The annular structure 10 and the first part of the structural shell 2 are designed as an integral structure, that is, the outer shell of the speaker 1 and at least the first part of the structural shell 2 are designed as an integral structure, thereby eliminating the key waterproof interface between the speaker 1 and the structural shell 2. Using the structural shell 2 as a part of the shell 7 of the electronic device 200 eliminates the key waterproof interface between the shell 7 of the electronic device 200 and the speaker 1, thereby reducing the risk of water ingress to the electronic device 200. In addition, the annular structure 10 and the structural shell 2 do not rely on external waterproof components such as rubber rings to achieve waterproofing, but directly eliminate the gap between the components, so that they can withstand stronger water flow impact, have higher reliability, and have stronger waterproof performance.
[0109] Therefore, the waterproof structure of the speaker module 100 provided in the embodiment of the present application has high reliability and good waterproof performance.
[0110] In one embodiment, the annular structure 10 is connected to the first portion of the structural shell 2 along its circumference. Thus, there is no gap between the annular structure 10 and the structural shell 2 along its circumference, completely eliminating the waterproof interface between the structural shell 2 and the loudspeaker 1, thereby achieving optimal waterproof performance. It should be noted that the annular structure 10 can be a separate component, a part of other components in the loudspeaker 1, or the other components can be used as the annular structure 10 as a whole. For example, the annular structure 10 can be a part of the fixed bracket 11 or a part of the cover 13, or the fixed bracket 11 or the cover 13 can be used as the annular structure 10 as a whole. Several examples are provided below with reference to the accompanying drawings.

[0112] As shown in Figures 5-9b , in one embodiment, the fixing bracket 11 of the loudspeaker 1 comprises an annular structure 10. Alternatively, it can be understood that the entire fixing bracket 11 or a portion thereof is formed as an annular structure 10 and connected to the first portion of the structural shell 2. As shown in Figures 5-9b , in one embodiment, the fixing bracket 11 is entirely formed as an annular structure 10, and the entire circumference of the fixing bracket 11 is connected to the first portion of the structural shell 2, forming an integral structure with the first portion.

[0114] As shown in Figures 11-13b, in one embodiment, the cover 13 of the speaker 1 includes an annular structure 10, or it can be understood that the entire cover 13 or a portion thereof serves as the annular structure 10, which is connected to the first portion of the structural shell 2. In one embodiment, the fixing bracket 11 is an annular structure 10 as a whole, and the entire circumference of the fixing bracket 11 is connected to the first portion of the structural shell 2 and is configured as an integral structure with the first portion.
[0115] As shown in Figures 4-13b, in one embodiment, the structural shell 2 of the speaker module 100 constitutes the back cover 72 of the electronic device 200. That is, the entire back cover 72 of the electronic device 200 serves as the structural shell 2. In this case, the thickness direction X of the speaker is parallel to the thickness direction Y of the electronic device. Furthermore, the entire back cover 72 of the electronic device 200 constitutes the first portion, and the entire back cover 72 and the annular structure 10 are integrally formed. In other alternative embodiments, only a portion of the back cover 72 may be integrally formed with the annular structure 10, and this application is not limited thereto.
[0116] As shown in Figures 5 to 13b, in one embodiment, the first portion of the structural shell 2 is provided with a receiving groove 20, and the annular structure 10 protrudes from the first portion of the structural shell 2 toward the inner side of the receiving groove 20. Alternatively, it can be understood that the speaker 1 is located in the receiving groove 20 of the structural shell 2, and the groove wall of the receiving groove 20 is connected to the annular structure 10 and is provided as an integrated structure. The specific structure and formation method of the receiving groove 20 are not limited. In one embodiment, the back cover 72 of the electronic device 200 has an annular boss 73 protruding toward the interior of the electronic device 200 (or it can be understood that the annular boss 73 is part of the back cover 72). The annular boss 73 constitutes the groove wall of the receiving groove 20, and the receiving groove 20 is formed inside the annular boss 73. It will be understood by those skilled in the art that the specific shape and structure of the annular boss 73 are not limited, and can be a circular ring, an elliptical ring, a rectangular ring, etc., and this application does not limit this. Furthermore, the shapes of the annular boss 73 and the annular structure 10 may be the same or different, as long as the annular boss 73 can enclose the speaker 1 in the receiving groove 20 . This application does not impose any limitation on this.
[0117] As shown in Figures 5-6 and 10a-10b, in the thickness direction X of the speaker, the annular structure 10 has a first surface 101 facing the screen 6, and the annular boss 73 also has a first surface 731 facing the screen 6. In one embodiment, the first surface 731 of the annular boss 73 is located on the side of the first surface 101 of the annular structure 10 that is closer to the screen 6. As shown in Figure 7, in one embodiment, the first surface 731 of the annular boss 73 can also be located on the side of the first surface 101 of the annular structure 10 that is farther away from the screen 6. As shown in Figure 11, in one embodiment, the first surface 731 of the annular boss 73 can also be located in the same horizontal plane as the first surface 101 of the annular structure 10, which is not limited in this application.
[0118] Please refer to Figures 14a-15, Figure 14a is a schematic diagram of the principle structure of the fifth embodiment of the speaker module of the embodiment of the present application; Figure 14b is a schematic diagram of the principle structure of the sixth embodiment of the speaker module of the embodiment of the present application; Figure 15 is a schematic diagram of the principle structure of the seventh embodiment of the speaker module of the embodiment of the present application.
[0119] As shown in Figures 14a to 15, in one embodiment, the structural shell 2 of the speaker module 100 constitutes the middle frame 71 of the electronic device 200, that is, the middle frame 71 of the electronic device 200 as a whole serves as the structural shell 2. At this time, the thickness direction X of the speaker is perpendicular to the thickness direction Y of the electronic device. As shown in Figure 14a, in one embodiment, the middle frame 71 of the electronic device 200 as a whole is the first part of the structural shell 2, that is, the entire middle frame 71 and the annular structure 10 are an integrated structure. As shown in Figures 14b to 15, in an alternative embodiment, the structural shell 2 includes a shell body 21 and a sound-emitting structure 22 (the sound-emitting structure 22 will be further described later), wherein the shell body 21 is the first part of the structural shell 2, and the part of the middle frame 71 that only constitutes the shell body 21 is an integrated structure with the annular structure 10. This application does not impose any restrictions on this.
[0120] Similarly, when the structural shell 2 of the speaker module 100 constitutes the middle frame 71 of the electronic device 200, the fixing bracket 11 can be used as the annular structure 10 (as shown in Figures 14a-14b) or the cover 13 can be used as the annular structure 10 (as shown in Figure 15), and this application does not limit this. The middle frame 71 can have an annular boss 73 (or it can be understood that the annular boss 73 is part of the middle frame 71), and the annular boss 73 forms a receiving groove 20 for accommodating the speaker 1. This application does not limit this.
[0121] It will be understood by those skilled in the art that, in addition to the need for waterproofing between the structural shell 2 and the speaker 1, there is also a water inlet path inside the speaker 1, which also needs to be waterproof. As shown in Figures 5 to 8b, Figures 10a to 12b, and Figures 14a to 15, in one embodiment, the outer peripheral edge of the vibrating member 12 is sealedly connected to the annular structure 10. Specifically, the outer peripheral edge of the diaphragm 121 is sealedly connected to the surface facing the annular structure 10. For example, as shown in Figures 5 to 8b, when the fixing bracket 11 as a whole serves as the annular structure 10, the outer peripheral edge of the diaphragm 121 is sealedly connected to the surface facing the fixing bracket 11. As shown in Figures 10a to 12b, when the cover body 13 as a whole serves as the annular structure 10, the outer peripheral edge of the diaphragm 121 is sealedly connected to the surface facing the cover body 13. The outer periphery of the diaphragm 121 is sealed to the annular structure 10, effectively sealing the annular structure 10 with the diaphragm 121. This blocks the water ingress path between the annular structure 10 and the diaphragm 121, and also blocks the water ingress path within the speaker 1 (i.e., the water ingress path between the fixing bracket 11 and the cover 13). The structural shell 2, the annular structure 10, and the diaphragm 121 are integrally connected in a plane perpendicular to the thickness direction X of the speaker, sealing the entire receiving groove 20 of the structural shell 2 and effectively preventing water from entering the electronic device 200.
[0122] It will be understood by those skilled in the art that there is no limit to the manner of sealing connection between the diaphragm 121 and the annular structure 10. In one embodiment, the outer peripheral edge portion of the diaphragm 121 and the annular structure 10 are sealed and bonded by waterproof adhesive. Among them, the waterproof adhesive can be butyl rubber, acrylic adhesive, polyurethane waterproof adhesive, silicone sealant, etc., and the present application does not limit the material and type of the waterproof adhesive. In an alternative embodiment, the outer peripheral edge portion of the diaphragm 121 and the annular structure 10 can also be integrally formed by an injection molding process. This structure can minimize the gap between the diaphragm 121 and the annular structure 10, improve the sealing and bonding firmness between the diaphragm 121 and the annular structure 10, and have better waterproof performance.
[0123] Please refer to FIG. 16 , which is a schematic diagram of the principle structure of the eighth embodiment of the speaker module according to the embodiment of the present application.
[0124] As shown in Figures 7 to 8a, 9a, 10a to 12a, and 14b to 16, in one embodiment, the structural shell 2 includes a shell body 21 and a sound-emitting structure 22, and the shell body 21 includes a first part. The sound-emitting structure 22 is fixedly and detachably connected to the shell body 21, and the sound-emitting structure 22 has a sound guide channel 23. Or it can be understood that the part of the structural shell 2 where the sound guide channel 23 is provided is set as a detachable independent component, and the sound-emitting structure 22 can be disassembled to facilitate cleaning of the sound guide channel 23 and reduce the maintenance cost of the electronic device 200. Among them, the sound-emitting structure 22 is detachably connected to the shell body 21 by any one or more methods of snapping, bonding, and magnetic attraction, and this application does not impose any restrictions on this.
[0125] It should be noted that when the sound-emitting structure 22 of the structural shell 2 is fixed and detachably connected to the shell body 21, the annular structure 10 can be set as an integrated structure with the first part of the structural shell 2 (as shown in Figures 7-8a, 9a, 10a-12a, 14b-15), or it can be a split structure (as shown in Figure 16), and this application does not impose any restrictions on this.
[0126] As shown in Figures 14b to 15, in one embodiment, the surface of the sound-emitting structure 22 away from the speaker 1 constitutes part of the outer surface of the middle frame 71. As shown in Figure 16, in one embodiment, the surface of the sound-emitting structure 22 away from the speaker 1 constitutes part of the outer surface of the back cover 72. The sound-emitting structure 22 is exposed outside the middle frame 71, which facilitates the disassembly of the sound-emitting structure 22. It should be noted that the surface of the sound-emitting structure 22 away from the speaker 1 can be exposed outside the structural shell 2. It can protrude from the surface of the shell body 21 on the side away from the speaker 1, be recessed into the surface of the shell body 21 on the side away from the speaker 1, or be flush with the surface of the shell body 21 on the side away from the speaker 1. This application does not impose any restrictions on this.
[0127] As shown in Figures 7-8a, 10a-12a, and 14a-16, the structural shell 2, the cover 13, and the surface of the vibrator 12 facing the cover 13 form a first sound cavity 31, and the inner wall surface of the fixed bracket 11 and the surface of the vibrator 12 facing the fixed bracket 11 form a second sound cavity 32. In one embodiment, the sound-emitting structure 22 is arranged opposite to the speaker 1, or it can be understood that the sound-emitting structure 22 and the diaphragm 121 are arranged opposite to each other in the thickness direction X of the speaker, and the extension direction of the sound guide channel 23 is parallel to the thickness direction X of the speaker. One end of the sound guide channel 23 is connected to the first sound cavity 31, and the other end extends to the outside of the structural shell 2, so as to connect the first sound cavity 31 with the outside of the structural shell 2 through the sound guide channel 23, and further connect the first sound cavity 31 with the outside of the electronic device 200.
[0128] Please refer to Figures 17a-17b. Figure 17a is a schematic diagram of the principle structure of the ninth embodiment of the speaker module of the embodiment of the present application; Figure 17b is a schematic diagram of the principle structure of the tenth embodiment of the speaker module of the embodiment of the present application.
[0129] As shown in Figures 17a and 17b, in an alternative embodiment, the sound-emitting structure 22 and the speaker 1 may also be arranged not facing each other, and the sound guide channel 23 and the first sound cavity 31 may be indirectly connected through other structures. Specifically, the structural shell 2 constitutes the back cover 72 of the electronic device 200, the thickness direction X of the speaker is parallel to the thickness direction Y of the electronic device, and the extension direction of the sound guide channel 23 is not parallel to the thickness direction X of the speaker. For example, in the scenario illustrated in Figures 17a and 17b, the extension direction of the sound guide channel 23 is perpendicular to the thickness direction X of the speaker. A connecting channel 24 is also provided in the shell body 21 of the structural shell 2. The connecting channel 24 is an L-shaped structure, one end of which is connected to the first sound cavity 31, and the other end is connected to the sound guide channel 23 on the sound-emitting structure 22. The first sound cavity 31 is connected to the outside of the structural shell 2 through the connecting channel 24 and the sound guide channel 23 in sequence. It should be noted that the specific shape of the connecting channel 24 is not limited, and can also be a curve shape, an arc shape, etc., as long as it can connect the first sound cavity 31 with the sound guide channel 23.
[0130] Those skilled in the art will understand that, in addition to the above-mentioned exemplified structures, the sound cavity of the speaker 1 can also be connected to the outside of the structural shell 2 in other ways, such as connecting the second sound cavity 32 to the outside of the structural shell 2, etc., and this application does not impose any restrictions on this.
[0131] As shown in Figures 7-8b, 10a-12b, and 14a-17a, in one embodiment, the speaker module 100 further includes a dustproof net 4, which can prevent debris from entering the sound cavity of the speaker module 100. In wading scenarios, it can effectively block some foreign matter, dust, etc., and is highly practical. In one embodiment, the dustproof net 4 is provided on the sound-emitting structure 22 so that the dustproof net 4 and the sound-emitting structure 22 can be disassembled together. In addition, the dustproof net 4 is located between the sound-emitting structure 22 and the speaker 1. After the sound-emitting structure 22 is disassembled, it is convenient to clean the debris in the sound cavity.
[0132] It should be noted that the dust-proof net 4 is provided between the sound-emitting structure 22 and the vibration member 12, which can be understood as the dust-proof net 4 is provided on the sound-emitting path between the vibration member 12 and the sound-emitting structure 22, and it can be located at any position between the vibration member 12 and the sound-emitting structure 22. As shown in Figure 8b and Figure 12b, in one embodiment, the dust-proof net 4 is provided on both the cover body 13 and the sound-emitting structure 22. Specifically, the outer peripheral edge portion of the dust-proof net 4 is bonded to the cover body 13 and the sound-emitting structure 22 on both sides of the thickness direction X of the speaker through the first adhesive portion 161 and the second adhesive portion 162 respectively. Among them, the material and type of the first adhesive portion 161 and the second adhesive portion 162 are not limited. In one embodiment, the first adhesive portion 161 and the second adhesive portion 162 are both waterproof glue to prevent the dust-proof net 4 from falling off in a water-related environment. As shown in Figures 17a and 17b, in one embodiment, the dust screen 4 can also be disposed between the sound-emitting structure 22 and the housing body 21, at the junction of the sound-emitting channel and the sound-guiding channel 23. Similarly, the dust screen 4 can be bonded between the sound-emitting structure 22 and the housing body 21 using a waterproof adhesive or other structure. In other alternative embodiments, the dust screen 4 can be installed in other locations, which is not limited by this application.
[0133] As shown in Figures 4-8a, 10a-12a, and 14a-17b, in one embodiment, the speaker module 100 further includes a pressure-bearing member 5, which is fixedly connected to the structural shell 2. The pressure-bearing member 5 may be made of a material such as stainless steel, which is not limited in this application. The pressure-bearing member 5 is fixed to the structural shell 2 and can withstand water pressure when the speaker 1 is impacted by water flow, making the installation of the speaker 1 more secure and reliable. Furthermore, the pressure-bearing member 5 can also be used to mount components such as the magnetic circuit assembly 15 of the speaker 1.
[0134] As shown in Figures 8a and 12a, in one embodiment, the magnetic circuit assembly 15 of the loudspeaker 1 includes a center magnet 152, edge magnets 153, and a first magnetic conductive plate 151, which are spaced apart. The first magnetic conductive plate 151 is fixed to the pressure member 5 and guides the direction of the magnetic field. The center magnet 152 is fixed to the first magnetic conductive plate 151, while the edge magnets 153 are arranged around the periphery of the axis magnet, with a gap between them and the center magnet 152. The voice coil 14 is annular and moves within the gap between the center and edge magnetic circuits. In one embodiment, the edge magnets 153 can be disposed on the fixed bracket 11, for example, by mounting the edge magnets 153 on the fixed bracket 11, or by directly forming the fixed bracket 11 from a magnetic material to form the edge magnets 153, thereby reducing the space occupied by the loudspeaker 1. In one embodiment, the magnetic circuit assembly 15 may also include a second magnetic conductive plate 154, which is disposed on the side of the center magnet 152 away from the first magnetic conductive plate 151. Those skilled in the art will appreciate that the arrangement of the magnets and magnetic conductive plates in the magnetic circuit assembly 15 should be specifically designed based on the desired magnetic field, and this application does not impose any restrictions thereto. In other alternative embodiments, the voice coil 14, magnetic circuit assembly 15, and pressure member 5 may also be configured in other configurations, and this application does not impose any restrictions thereto.
