Description

Technical Field

[0001] This application relates to the field of audio technology, and more particularly to a loudspeaker and electronic device. Background Technology

[0002] Miniature speakers are widely used in electronic devices such as headphones, glasses, and mobile phones. As electronic devices continue to evolve towards thinner and smaller designs, especially headphones which require comfortable wear, there are high demands on the slim and lightweight design of these products. Limited internal space necessitates that speakers have a small footprint.

[0003] However, the electrical connectors of existing loudspeakers occupy too much space in the circumferential direction of the loudspeaker, resulting in an increase in the size of the loudspeaker in the circumferential direction. This not only hinders the miniaturization of the loudspeaker, but also limits the size of the diaphragm. Summary of the Invention

[0004] This application provides a loudspeaker and an electronic device. The loudspeaker is small in size and has a simple structure. The electronic device including the loudspeaker is easy to assemble and is also small in size.

[0005] In a first aspect, embodiments of this application provide a loudspeaker. The loudspeaker includes a frame, a magnetic circuit assembly, a first diaphragm, a first voice coil, a first electrical connector, and a second electrical connector. The magnetic circuit assembly is fixedly connected to the frame, and the periphery of the first diaphragm is fixed to the frame and located on one side of the magnetic circuit assembly. The magnetic circuit assembly has a first magnetic gap. One end of the first voice coil is fixedly connected to the first diaphragm, and the other end is located in the first magnetic gap. The frame includes an outer side and an inner side facing away from each other. The first electrical connector is electrically connected to the first voice coil, and at least a portion of the first electrical connector is embedded in the frame, with a portion of the first electrical connector exposed relative to the outer side of the frame. At least a portion of the second electrical connector is located on the outer side of the frame away from the inner side of the frame. One end of the second electrical connector is fixedly connected to and electrically connected to the first electrical connector, and the other end of the second electrical connector extends beyond the edge of the first diaphragm to the side of the first diaphragm facing away from the frame.

[0006] It is understood that in the embodiments of this application, the first voice coil can be electrically connected to an external power source through a first electrical connector and a second electrical connector, so that the external power source can energize the first voice coil. After the first voice coil is energized, it can vibrate to drive the first diaphragm to vibrate, thereby realizing the sound production of the loudspeaker.

[0007] In this embodiment, the other end of the second electrical connector can be located on the side of the first diaphragm away from the frame, so that the other end of the second electrical connector will not occupy too much space in the circumferential direction of the speaker, which is beneficial to reducing the circumferential size of the speaker and thus to miniaturizing the speaker.

[0008] Furthermore, in this embodiment, by placing the second electrical connector on the outside of the basin frame, compared to the solution where the second electrical connector is embedded in the basin frame, the second electrical connector in this embodiment does not occupy the space inside the basin frame, allowing the diameter of the first diaphragm to be larger, thereby allowing the total area of ​​the first diaphragm to be larger.

[0009] It is understandable that the maximum low-frequency output capability of a loudspeaker depends on the maximum displacement volume (Vdmax) of the loudspeaker diaphragm in one direction. The maximum low-frequency output capability of a loudspeaker is positively correlated with the maximum displacement volume of the diaphragm; increasing the maximum displacement volume can improve the maximum low-frequency output capability of the loudspeaker, thereby improving the sound quality. From Vdmax = Sd * Xmax, it can be seen that the maximum displacement volume (Vdmax) of the loudspeaker diaphragm in one direction is related to the effective radiation area (Sd) and the maximum amplitude (Xmax) of the diaphragm. Increasing the effective radiation area or the maximum amplitude of the diaphragm can increase the maximum displacement volume of the diaphragm, thereby improving the maximum low-frequency output capability of the loudspeaker. In the embodiments of this application, the first diaphragm has a larger effective radiation area, which is beneficial for increasing the maximum displacement volume of the first diaphragm, enabling the loudspeaker to have a better maximum low-frequency output capability.

[0010] Secondly, by placing the second electrical connector on the outside of the basin frame, the second electrical connector can be indirectly fixed to the basin frame through the first electrical connector. Compared with the solution of embedding the second electrical connector in the basin frame, the assembly between the second electrical connector and the basin frame is simpler, which helps to simplify the assembly process of the second electrical connector. In addition, the structure and molding process of the basin frame are simpler, which helps to improve production efficiency and reduce costs.

[0011] In some embodiments, the loudspeaker also includes a housing that is fixedly connected to a frame, at least a portion of the first diaphragm being located between the housing and the frame; the other end of the second electrical connector also passes through the housing and protrudes relative to the housing.

[0012] In this embodiment, the housing can cover at least a portion of the first diaphragm to protect it. Furthermore, the second electrical connector can be securely connected to the frame via the fixing portion of the housing, thereby increasing the strength of the connection between the second electrical connector and the frame and reducing the risk of the second electrical connector detaching.

[0013] In some embodiments, the housing includes a shell portion and a fixing portion, the edge of the shell portion having a notch, at least a portion of the fixing portion being located at the notch and fixedly connected to the shell portion; a second electrical connector is disposed through the fixing portion and extends away from the basin frame relative to the fixing portion, the fixing portion being insulated from the first electrical connector.

[0014] In this embodiment, the first electrical connector can not only be fixedly connected to the basket frame through the fixing part of the housing, but also be insulated from the speaker or other components other than the speaker through the fixing part of the housing, thereby reducing the risk of short circuit when the first electrical connector is electrically connected to an external power source.

[0015] In some embodiments, the second electrical connector includes a first connecting portion and a second connecting portion, the second connecting portion being connected to the first connecting portion, at least a portion of the first connecting portion being located on the outer side of the outer surface and connected to the first electrical connector, and at least a portion of the second connecting portion being located on the side of the first diaphragm away from the frame; the second connecting portion is bent relative to the first connecting portion toward the frame.

[0016] It is understood that in this embodiment, by bending the second connecting portion of the second electrical connector relative to the first connecting portion, the first connecting portion can be located on the outer side of the outer side of the frame to connect the first electrical connector, while the second connecting portion can be located on the side of the first diaphragm away from the frame, so as to make reasonable use of the space on the side of the first diaphragm away from the frame. Thus, the second connecting portion will not occupy too much space in the circumferential direction of the speaker, which is conducive to reducing the circumferential size of the speaker and thus conducive to the miniaturization of the speaker.

[0017] In some embodiments, the second connecting portion includes a first segment and a second segment, the first segment being connected between the second segment and the first connecting portion, the first segment being bent toward the direction of the frame relative to the first connecting portion; the second segment being set at an angle to the first segment, the length extension direction of the second segment being parallel to the axial direction of the speaker.

[0018] In this embodiment, the second connection portion of the second electrical connector can be located entirely on the side of the first diaphragm away from the frame, without occupying the circumferential space of the speaker. Thus, when the speaker is installed in the internal space of the electronic device, the space on the outer periphery of the speaker can be used to house other components of the electronic device. In other words, the speaker can be used to avoid interference with other components located inside the electronic device.

[0019] It is understood that, in this application, the shape of the second connecting portion of the second electrical connector can be set according to the specific position of the speaker inside the electronic device and the arrangement requirements of the internal components of the electronic device, so as to avoid interference between the second electrical connector of the speaker and other internal components of the electronic device. The setting of the second electrical connector can be more flexible and has a wider range of applications.

[0020] In some embodiments, the loudspeaker further includes a housing, which is fixedly connected to a frame, with at least a portion of the first diaphragm located between the housing and the frame; the housing includes a shell portion and a fixing portion, the fixing portion being fixedly connected to the edge of the shell portion; the fixing portion includes a first surface and a second surface, the first surface and the second surface being disposed opposite to each other in the axial direction of the loudspeaker, the fixing portion having a first through hole, one end of the first through hole being open on the first surface and the other end being open on the second surface; a second electrical connector passes through the first through hole, and a second segment of the second electrical connector is exposed relative to the first surface.

[0021] In this embodiment, the first through hole can be curved. The length extension direction of the second segment can be parallel to the axial direction of the speaker. By providing the first through hole in the fixing part, the second electrical connector can be fixed to the housing through the first through hole, and the second segment of the second connecting part of the second electrical connector can be exposed through the first through hole to the first surface of the fixing part for electrical connection to an external power source.

[0022] It is understood that, in this application, the shape of the first through hole of the fixing part of the housing and the position of the opening can be adjusted according to the shape of the second connecting part of the second electrical connector to adapt to the shape of the second connecting part of the second electrical connector.

[0023] In some embodiments, the second connecting portion includes a first segment and a second segment, the first segment being connected between the second segment and the first connecting portion, the first segment being bent toward the direction of the frame relative to the first connecting portion; the second segment being set at an angle to the first segment, and the length extension direction of the second segment being set at an angle to the axis of the speaker.

[0024] In this embodiment, the second segment of the second connection portion of the second electrical connector can extend toward the outer periphery of the speaker, so that when the speaker is installed in the internal space of the electronic device, the space on the side of the first diaphragm away from the frame can be used to house other components of the electronic device. That is, the speaker can be used to avoid other components located in the internal space and avoid interference with other components inside the electronic device.

[0025] It is understood that, in this application, the shape of the second connecting portion of the second electrical connector can be set according to the specific position of the speaker inside the electronic device and the arrangement requirements of the internal components of the electronic device, so as to avoid interference between the second electrical connector of the speaker and other internal components of the electronic device. The setting of the second electrical connector can be more flexible and has a wider range of applications.

[0026] In some embodiments, the loudspeaker further includes a housing, which is fixedly connected to a frame, with at least a portion of the first diaphragm located between the housing and the frame; the housing includes a shell portion and a fixing portion, the fixing portion being fixedly connected to the edge of the shell portion; the fixing portion includes a first surface, a second surface, and a third surface, the first surface and the second surface being disposed opposite to each other in the axial direction of the loudspeaker, the third surface being disposed at an angle to the first surface, the fixing portion having a first through hole, one end of the first through hole being located on the third surface, and the other end being located on the second surface; a second electrical connector passes through the first through hole, and a second segment of the second electrical connector is exposed relative to the third surface.

[0027] In this embodiment, the first through hole can be curved. The length extension direction of the second segment can be set at an angle to the axial direction of the speaker. By providing the first through hole in the fixing part, the second electrical connector can be fixed to the housing through the first through hole, and the second segment of the second connecting part of the second electrical connector can be exposed through the first through hole to the third surface of the fixing part for electrical connection to an external power source.

[0028] It is understood that, in this application, the shape of the first through hole of the fixing part of the housing and the position of the opening can be adjusted according to the shape of the second connecting part of the second electrical connector to adapt to the shape of the second connecting part of the second electrical connector.

[0029] In some embodiments, the first electrical connector includes a first side and a second side facing away from each other. The first side of the first electrical connector faces the outer side of the speaker frame and connects to the second electrical connector. The distance between the second side of the first electrical connector and the outer side of the speaker frame is H1, where H1 ≤ 0.45 mm. This way, the second electrical connector does not occupy excessive space in the circumferential direction of the speaker, which helps to reduce the circumferential size of the speaker and thus facilitates miniaturization. In some examples, the distance between the second side of the first electrical connector and the outer side of the speaker frame can be less than or equal to 0.2 mm.

[0030] In some embodiments, the second electrical connector includes a first lead and a first solder pin; the first solder pin is located on the side of the first diaphragm facing away from the frame and is fixedly connected to the frame; one end of the first lead is connected to the first electrical connector, and the other end extends beyond the edge of the first diaphragm to the side of the first diaphragm facing away from the frame; the other end of the first lead is connected to the first solder pin.

[0031] It is understandable that the first lead is a flexible component and can deform. Using the lead to achieve the electrical connection between the first welding pin and the first electrical connector, compared to a solution using a rigid component, the positions of the first welding pin and the first electrical connector in this embodiment are less likely to be restricted by each other. That is, the positions of the first welding pin and the first electrical connector can be adjusted as needed, making their placement more flexible and thus broadening the applicability of the first electrical connection assembly.

[0032] In some implementations, the diameter of the first lead is less than or equal to 0.1 mm. This reduces the space occupied by the first lead in the circumferential direction of the speaker, which helps to reduce the circumferential size of the speaker and thus facilitates the miniaturization of the speaker.

[0033] In some implementations, the first lead includes a 3D-printed lead or a cable. In some examples, the first lead can be a 3D-printed lead, meaning it can be manufactured using 3D printing technology. It is understood that the first lead can be connected between the first electrical connector and the first welding pin via 3D printing, which helps to improve the strength and reliability of the connection between the first lead and the first electrical connector / welding pin.

[0034] In some embodiments, the loudspeaker further includes a second diaphragm, a second voice coil, a fifth electrical connector, and a sixth electrical connector. The periphery of the second diaphragm is fixed to the frame, the magnetic circuit assembly has a second magnetic gap, one end of the second voice coil is fixedly connected to the second diaphragm, and the other end is located in the second magnetic gap. The fifth electrical connector is electrically connected to the second voice coil, at least a portion of the fifth electrical connector is embedded in the frame, and a portion of the fifth electrical connector is exposed relative to the outer side of the frame. The fifth electrical connector is spaced apart from the first electrical connector. At least a portion of the sixth electrical connector is located on the outer side of the frame away from the inner side and is spaced apart from the second electrical connector. One end of the sixth electrical connector is fixedly connected to and electrically connected to the fifth electrical connector, and the other end of the sixth electrical connector extends beyond the edge of the first diaphragm to the side of the first diaphragm facing away from the frame.

[0035] Understandably, in this embodiment, the second voice coil can be electrically connected to an external power source via a fifth electrical connector and a sixth electrical connector, allowing the external power source to energize the first voice coil. When energized, the second voice coil vibrates, driving the second diaphragm to vibrate, thereby producing sound from the speaker. In some examples, the sound produced by the second diaphragm can be superimposed with the sound produced by the first diaphragm, thus improving the speaker's sound quality.

[0036] In this embodiment, the other end of the sixth electrical connector can be located on the side of the first diaphragm away from the frame, so that the other end of the sixth electrical connector will not occupy too much space in the circumferential direction of the speaker, which is beneficial to reducing the circumferential size of the speaker and thus facilitating the miniaturization of the speaker.

[0037] Furthermore, in this embodiment, by placing the sixth electrical connector on the outside of the basket, compared to the solution where the second electrical connector is embedded in the basket, the second electrical connector in this embodiment does not occupy the space inside the basket, allowing the diameter of the first diaphragm to be larger, thereby increasing the effective radiation area of ​​the first diaphragm and thus improving the maximum displacement volume of the first diaphragm, enabling the speaker to have better low-frequency maximum output capability.

[0038] Secondly, by placing the sixth electrical connector on the outside of the basin frame, the sixth electrical connector can be indirectly fixed to the basin frame through the fifth electrical connector. Compared with the solution of embedding the sixth electrical connector in the basin frame, the assembly between the sixth electrical connector and the basin frame is simpler, which helps to simplify the assembly process of the sixth electrical connector. In addition, the structure and molding process of the basin frame are simpler, which helps to improve production efficiency and reduce costs.

[0039] In some embodiments, the first electrical connector includes a first portion and a second portion, the second portion being connected to the first portion and bent relative to the first portion; at least a portion of the first portion is embedded in the basket frame, the first portion including a first connecting surface exposed relative to the outer side of the basket frame; at least a portion of the second portion is embedded in the basket frame, the second portion including a second connecting surface located on the inner side of the basket frame, the second connecting surface exposed relative to the basket frame, and electrically connected to the first voice coil.

[0040] In this embodiment, by bending the second part of the first electrical connector relative to the first part, the first connecting surface of the first electrical connector can have a larger exposed area relative to the outer side of the basin frame, which is beneficial to the firmness and reliability of the connection between the first electrical connector and the second electrical connector.

[0041] In some embodiments, the first electrical connector and the second electrical connector are fixedly connected by metal welding. This provides a strong connection and good electrical connection reliability between the second and first electrical connectors. It is understood that metal welding may include, but is not limited to, laser welding and soldering.

[0042] Secondly, embodiments of this application also provide an electronic device. The electronic device includes a housing and the aforementioned speaker, with the speaker mounted on the housing. The electronic device in this application embodiment is small in size and relatively easy to assemble.

[0043] In some embodiments, the housing is provided with a sound outlet that communicates with the space on the side of the first diaphragm near the frame; the electronic device also includes a first circuit board and a second circuit board, both of which are mounted on the housing. The first circuit board is located on the side of the speaker away from the sound outlet, and a portion of the second circuit board is located between the speaker and the first circuit board and is electrically connected to the first electrical connector and the first circuit board.

[0044] It is understood that in this embodiment, the inner diameter of the outer casing is larger, i.e., the space is larger, at the position away from the sound outlet. By placing the third part of the second circuit board on the side of the speaker away from the sound outlet, the connection position between the second circuit board and the first electrical connector of the speaker can be located on the side of the speaker away from the sound outlet. This allows for a larger assembly space between the second circuit board and the first electrical connector of the speaker, which helps to reduce the assembly difficulty of the speaker and the second circuit board.

[0045] Furthermore, in this embodiment, the third portion of the second circuit board can be located between the first circuit board and the speaker, and directly electrically connected to the first circuit board. This eliminates the need for additional electrical connection structures on the side of the speaker's first diaphragm away from the frame to achieve circuit connectivity between the second and first circuit boards. This reduces the stacking space of components along the speaker axis, thereby reducing the size of the electronic device along the speaker axis and promoting miniaturization.

[0102] It is understood that the specific embodiments described herein are merely illustrative of related embodiments and not intended to limit the scope of those embodiments. Furthermore, it should be noted that, for ease of description, only the parts relevant to the embodiments are shown in the accompanying drawings.

[0103] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0104] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0105] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the electronic device 100 provided in this application in some embodiments.

[0106] In some embodiments, the electronic device 100 may be a device with audio playback capabilities, such as headphones, mobile phone, tablet computer, multimedia player, speaker, laptop computer, in-vehicle device, foldable terminal device, or wearable device. Wearable devices may include smart bracelets, smartwatches, smart headsets, smart glasses, etc. This application does not strictly limit the type of electronic device 100.

[0107] Figure 1 The electronic device 100 shown is illustrated using headphones as an example. It is understood that the headphones can be wireless or wired. Wireless headphones can communicate with the terminal device using electromagnetic waves. Examples include Bluetooth headphones and infrared headphones. Wired headphones can communicate with the terminal device via a wire.

[0108] For example, the electronic device 100 may include a housing 10 and a speaker 20. The speaker 20 may be housed within the housing 10. The speaker 20 is used to convert electrical signals into sound signals, which can be transmitted through the housing 10 to the outside of the electronic device 100 to achieve sound playback. The housing 10 of the electronic device 100 is the earpiece of an earphone, which is the main structure of the earphone. The earphone may also include an ear stem 30 (also called an ear stick). The ear stem 30 is fixed to the housing 10. For example, the ear stem 30 may be fixed to the side or bottom of the housing 10. For example, the housing 10 of the electronic device 100 may be provided with a sound outlet 101. The sound emitted by the speaker 20 can be transmitted out of the electronic device 100 through the sound outlet 101 to be received by the user.

[0109] For example, the electronic device 100 may further include a first circuit board 40, a power supply 50 (i.e., a battery), and a microphone 60. The first circuit board 40 may be housed within the housing 10. The power supply 50 and the microphone 60 may be housed within the ear stem 30. The power supply 50 supplies power to the electronic device 100, and the microphone 60 converts sound signals into electrical signals to enable the electronic device 100 to pick up sound. In some embodiments, the microphone 60 may be located at the bottom of the ear stem 30, or at other locations on the ear stem 30 or within the housing 10. In some embodiments, the number of microphones 60 may be one or more. When there are multiple microphones 60, they may be arranged in different locations within the electronic device 100.

[0110] In some embodiments, the electronic device 100 can be a wireless headset.

The second diaphragm 241 and the second voice coil 242 can form a second vibration assembly, whereby the second voice coil 242 can be energized to vibrate and drive the second diaphragm 241 to vibrate, thereby enabling the loudspeaker 20 to produce sound.

[0114] Understandable, Figure 3 The accompanying drawings below only schematically illustrate some of the components included in the speaker 20; the actual shape, size, location, and construction of these components are not subject to change. Figure 3As defined in the accompanying drawings below. It will be understood that the speaker 20 may include more or fewer parts. In some other embodiments, the speaker 20 may include fewer components. For example, the speaker 20 may also exclude the second vibration assembly, the third electrical connection assembly 27, and the fourth electrical connection assembly 28. For example, the speaker 20 may also exclude the housing 29.

[0115] For example, the speaker 20 can be a circular speaker 20. The central axis A1-A1 of the speaker 20 can pass through the center of the frame 21, the magnetic circuit assembly 22, the first diaphragm 231, and the second diaphragm 241. It is understood that all references to "axial" below refer to the direction of extension of the central axis A1-A1, and "circumferential" refers to the direction perpendicular to the central axis. In other embodiments, the speaker 20 may also be square or other shapes, which are not strictly limited in this application.

For example, Figure 10A and Figure 10B The first connecting portion 2523 and the second connecting portion 2524 are schematically divided by dashed lines. For example, along the length extension direction of the first connecting portion 2523, the second connecting portion 2524 may be located on one side of the first connecting portion 2523.

[0134] In some embodiments, the second connection portion 2524 of the second electrical connector 252 may include a first segment 2525 and a second segment 2526.

For example, the angle between the second segment 2526 of the second electrical connector 252 and the first segment 2525 may be in the range of 0° to 180°. For example, the length extension direction of the second segment 2526 of the second connecting portion 2524 of the second electrical connector 252 is set at an angle to the length extension direction of the first connecting portion 2523.

[0137] In some embodiments, the first electrical connector 251 may include a first portion 2511 and a second portion 2512.

The first segment 2525a can be bent relative to the first connecting part 2523.

[0141] For example, the third segment 2526b may be bent relative to the first segment 2525a. For instance, the third segment 2526b and the first segment 2525a may be perpendicular. In some examples, the length extension direction of the third segment 2526b may be parallel to the length extension direction of the first connecting portion 2523.

In this case, the first connecting portion 2723 of the sixth electrical connector 272 and the first portion 2711 of the fifth electrical connector 271 may be located on opposite sides of the second portion 2712 of the fifth electrical connector 271. The second part 2712 of the fifth electrical connector 271 may be located on the side of the first part 2711 away from the second connection portion 2724 of the sixth electrical connector 272.

[0157] Please see Figure 3 In this embodiment, the fourth electrical connection assembly 28 may include a seventh electrical connector 281 and an eighth electrical connector 282. The eighth electrical connector 282 is fixedly connected to and electrically connected to the seventh electrical connector 281. For example, the eighth electrical connector 282 may be fixedly connected to and electrically connected to the seventh electrical connector 281 by metal welding. This provides a strong connection and reliable electrical connection between the eighth electrical connector 282 and the seventh electrical connector 281. It is understood that metal welding may include, but is not limited to, laser welding and soldering.

[0158] In this embodiment, the structure and materials of the fourth electrical connection component 28 can be the same as those of the third electrical connection component 27. The basic design of the component structure of the fourth electrical connection component 28, the design of the connection relationships between components, and the design of the connection relationships between components and other structures outside the component can all refer to the relevant schemes of the third electrical connection component 27. At the same time, slight differences in the detailed structure or positional arrangement of components are allowed between the fourth electrical connection component 28 and the third electrical connection component 27. Specific details will not be elaborated here. In other embodiments, the fourth electrical connection component 28 and the third electrical connection component 27 can also have similar structures, symmetrical or partially symmetrical structures, or different structures. This application does not impose strict limitations on these aspects.

[0159] Please refer to the following: Figures 13A to 14 , Figure 13A yes Figure 2 The diagram shown is a partial structural schematic of the speaker 20 in some embodiments. Figure 13B yes Figure 13A The diagram shows a partial structure of the speaker 20 from another angle. Figure 14 yes Figure 13B The diagram shows a partial cross-sectional view of the speaker 20 taken along point CC. For example, Figure 13A The diagram mainly shows the assembly structure of the basin frame 21, the first electrical connection assembly 25, the second electrical connection assembly 26, the third electrical connection assembly 27, and the fourth electrical connection assembly 28.

[0160] In some embodiments, the first electrical connection assembly 25 is fixedly connected to the basin frame 21.

[0161] For example, the first electrical connector 251 can be embedded in the basin stand 21. For instance, the first electrical connector 251 can be embedded in the upper basin stand 211. At least a portion of the first part 2511 of the first electrical connector 251 can be located in the first recess 2141. It is understood that the first part 2511 of the first electrical connector 251 can be exposed relative to the outer surface 2133 of the basin stand 21. The first part 2511 can be entirely located within the second receiving groove 2152, or it can be partially located within the second receiving groove 2152. For example, a portion of the first part 2511 can be located within the first recess 2141, and a portion can be located within the first through hole 2161.

[0162] Exemplarily, the first connecting surface 2513 of the first electrical connector 251 may be exposed relative to the first recess 2141. It is understood that the first connecting surface 2513 may be exposed relative to the outer side surface 2133 of the basin holder 21. In this case, the first connecting surface 2513 of the first electrical connector 251 may be positioned opposite to the inner side surface 2134 of the basin holder 21. In some examples, the first connecting surface 2513 of the first electrical connector 251 may be flush with the outer side surface 2133 of the basin holder 21. In other examples, the first connecting surface 2513 of the first electrical connector 251 may also be located within the first recess 2141. It is understood that the first connecting surface 2513 may be recessed relative to the outer side surface 2133 of the basin holder 21. This application does not impose strict limitations on this.

[0163] At least a portion of the second portion 2512 of the first electrical connector 251 may be located within the first receiving groove 2151. It is understood that the second portion 2512 of the first electrical connector 251 may be exposed relative to the first surface 2131 of the basin holder 21. The second portion 2512 of the first electrical connector 251 may be entirely located within the first receiving groove 2151, or it may be partially located within the first receiving groove 2151. For example, a portion of the second portion 2512 of the first electrical connector 251 may be located within the first receiving groove 2151, and a portion may be located within the first through hole 2161.

[0164] Exemplarily, the second connecting surface 2514 of the first electrical connector 251 may be exposed relative to the first receiving groove 2151. It is understood that the second connecting surface 2514 may be located inside the basin holder 21 and exposed relative to the first surface 2131 of the basin holder 21. In this case, the second connecting surface 2514 of the first electrical connector 251 may be positioned opposite to the second surface 2132 of the basin holder 21. In some examples, the second connecting surface 2514 may be flush with the surface of the first protrusion 215 of the basin holder 21. In other examples, the second connecting surface 2514 of the first electrical connector 251 may also protrude from the first receiving groove 2151. In still other examples, the second connecting surface 2514 may also be located within the first receiving groove 2151. This application does not impose strict limitations on these aspects.

[0165] In some embodiments, the second electrical connector 252 is fixedly connected to the first electrical connector 251 and is located on the outside of the basin stand 21. Exemplarily, one end of the second electrical connector 252 is fixedly connected to and electrically connected to the first electrical connector 251, and the other end extends beyond the edge of the basin stand 21 to the side of the first surface 2131 of the basin stand 21 away from the second surface 2132. For example, a portion of the first connecting portion 2523 of the second electrical connector 252 may be located outside the outer surface 2133, and a portion may extend across the edge of the basin stand 21 to the side of the first surface 2131 of the basin stand 21 away from the second surface 2132. It is understood that all descriptions of "the other end of the second electrical connector 252" below refer to the end of the second electrical connector 252 away from the first electrical connector 251.

[0166] For example, the first side 2521 of the first connecting portion 2523 of the second electrical connector 252 can be disposed opposite to the first groove 2141 of the basin holder 21 and connected to the first connecting surface 2513 of the first electrical connector 251. In this embodiment, by bending the second portion 2512 of the first electrical connector 251 relative to the first portion 2511, the first connecting surface 2513 of the first electrical connector 251 can have a larger exposed area relative to the outer side 2133 of the basin holder 21, thereby improving the firmness and reliability of the connection between the first electrical connector 251 and the second electrical connector 252.

[0167] For example, the second side 2522 of the second electrical connector 252 is disposed opposite to the outer side 2133 of the frame 21. The distance between the second side 2522 and the outer side 2133 is H1, where H1 ≤ 0.45 mm. For example, H1 ≤ 0.2 mm. In this way, the second electrical connector 252 does not occupy too much space in the circumferential direction of the speaker 20, which helps to reduce the circumferential size of the speaker 20, thereby facilitating the miniaturization of the speaker 20.

[0168] In some examples, the length extension direction of the first connecting portion 2523 of the second electrical connector 252 may be parallel to the axial direction of the speaker 20. In other examples, the length extension direction of the first connecting portion 2523 may also be set at an angle to the axial direction of the speaker 20; this application does not strictly specify this.

[0169] For example, at least a portion of the second connecting portion 2524 of the second electrical connector 252 may be located on the side of the first surface 2131 of the basin frame 21 away from the second surface 2132. It is understood that, in this embodiment, the second connecting portion 2524 of the second electrical connector 252 may be entirely located on the side of the first surface 2131 of the basin frame 21 away from the second surface 2132. In other embodiments, the second connecting portion 2524 of the second electrical connector 252 may also be partially located on the side of the first surface 2131 of the basin frame 21 away from the second surface 2132. The length extension direction of the first segment 2525 of the second connecting portion 2524 may be angled with the axial direction of the speaker 20, and the first segment 2525 may be bent relative to the first connecting portion 2523 towards the first surface 2131 of the basin frame 21. In this embodiment, the length extension direction of the second segment 2526 of the second connecting portion 2524 of the second electrical connector 252 may be at an angle to the axial direction of the speaker 20, and the second segment 2526 may extend away from the frame 21 relative to the first segment 2525. In some other examples, the length extension direction of the second segment 2526 may also be parallel to the axial direction of the speaker 20. This application does not impose strict limitations on this.

[0170] In this embodiment, by bending the second connecting portion 2524 of the second electrical connector 252 relative to the first connecting portion 2523, the first connecting portion 2523 can be located on the outer side 2133 of the frame 21 to connect to the first electrical connector 251, while the second connecting portion 2524 can be located on the side of the first diaphragm 231 away from the frame 21, so as to make reasonable use of the space on the side of the first diaphragm 231 away from the frame 21. Thus, the second connecting portion 2524 will not occupy too much space in the circumferential direction of the speaker 20, which is conducive to reducing the circumferential size of the speaker 20, and thus conducive to the miniaturization of the speaker 20.

It is understood that all descriptions of "the other end of the fourth electrical connector 262" below refer to the end of the fourth electrical connector 262 away from the third electrical connector 261.

It is understood that the first part 2711 of the fifth electrical connector 271 can be exposed relative to the outer surface 2133 of the basin holder 21. The first part 2711 can be entirely located within the third receiving groove 2171, or it can be partially located within the third receiving groove 2171. For example, a portion of the first part 2711 can be located within the third recess 2143, and a portion can be located within the third through hole 2181.

In some examples, the first connecting surface 2713 of the fifth electrical connector 271 may be flush with the outer side surface 2133 of the basin holder 21. In other examples, the first connecting surface 2713 of the fifth electrical connector 271 may also be located within the third recess 2143. It is understood that the first connecting surface 2713 may be recessed relative to the outer side surface 2133 of the basin holder 21. This application does not impose strict limitations on this.

[0180] At least a portion of the second portion 2712 of the fifth electrical connector 271 may be located within the third receiving groove 2171. It is understood that the second portion 2712 of the fifth electrical connector 271 may be exposed relative to the first surface 2131 of the basin holder 21. The second portion 2712 of the fifth electrical connector 271 may be entirely located within the third receiving groove 2171, or may be partially located within the third receiving groove 2171.

In other examples, the second connecting surface 2714 of the fifth electrical connector 271 may also protrude from the third receiving groove 2171. In still other examples, the second connecting surface 2714 may also be located within the third receiving groove 2171. This application does not impose strict limitations on these aspects.

[0182] In some embodiments, the sixth electrical connector 272 is fixedly connected to the fifth electrical connector 271 and is located on the outside of the basin stand 21. Exemplarily, one end of the sixth electrical connector 272 is fixedly connected to and electrically connected to the fifth electrical connector 271, and the other end extends beyond the edge of the basin stand 21 to the side of the first surface 2131 of the basin stand 21 away from the second surface 2132.

It is understood that all descriptions of "the other end of the sixth electrical connector 272" below refer to the end of the sixth electrical connector 272 away from the fifth electrical connector 271.

[0183] For example, the first side 2721 of the first connecting portion 2723 of the sixth electrical connector 272 can be disposed opposite to the third groove 2143 of the basin stand 21 and connected to the first connecting surface 2713 of the fifth electrical connector 271.

[0184] For example, the second side 2722 of the sixth electrical connector 272 is disposed opposite to the outer side 2133 of the frame 21. The distance between the second side 2722 and the outer side 2133 of the sixth electrical connector 272 is H2, where H2 ≤ 0.45 mm. For example, H2 ≤ 0.2 mm. In this way, the sixth electrical connector 272 does not occupy too much space in the circumferential direction of the speaker 20, which helps to reduce the circumferential size of the speaker 20, thereby facilitating the miniaturization of the speaker 20.

In other examples, the length extension direction of the first connecting portion 2723 may also be set at an angle to the axial direction of the speaker 20; this application does not strictly specify this.

[0186] For example, the second connecting portion 2724 of the sixth electrical connector 272 can be located on the side of the first surface 2131 of the frame 21 facing away from the second surface 2132.

[0194] In some embodiments, the first diaphragm 231 is fixedly connected to the frame 21. For example, the periphery of the first diaphragm 231 may be fixedly connected to the first surface 2131 of the frame 21.

[0195] For example, the first diaphragm 231 may include a vibrating part 2311, a folded ring part 2312, and a fixing part 2313.

The fixing part 2313 can be fixedly connected to the first surface 2131 of the speaker frame 21. The folded ring part 2312 may be deformable. For example, the folded ring part 2312 may be a ring structure with an overall arc surface. This arc-shaped ring structure is easy to deform and stretch so that the vibrating part 2311 can be displaced relative to the fixing part 2313 in the axial direction of the speaker 20.

[0196] In some embodiments, the second diaphragm 241 is fixedly connected to the basin frame 21. Exemplarily, the periphery of the second diaphragm 241 may be fixedly connected to the second surface 2132 of the basin frame 21. It is understood that the first diaphragm 231 and the second diaphragm 241 may be located on opposite sides of the basin frame 21.

[0197] For example, the second diaphragm 241 may have a first through-hole 2410. The first through-hole 2410 may be located in the middle of the second diaphragm 241. The first through-hole 2410 may connect the internal space of the speaker 20 to the outside of the speaker 20. In some examples, the periphery of the first through-hole 2410 may be fixedly connected to the magnetic circuit assembly 22. For example, the periphery of the first through-hole 2410 may be fixedly connected to the center magnet of the magnetic circuit assembly 22.

[0200] In some embodiments, the magnetic circuit assembly 22 may be located inside the frame 21 and fixedly connected to the frame 21. For example, in the axial direction of the speaker 20, the magnetic circuit assembly 22 may be located between the first diaphragm 231 and the second diaphragm 241, that is, the first diaphragm 231 and the second diaphragm 241 may be located on opposite sides of the magnetic circuit assembly 22.

[0201] In some embodiments, the magnetic circuit assembly 22 may include a central magnet 221 and side magnets 222. The side magnets 222 may be arranged around the central magnet 221. Exemplarily, the number of side magnets 222 may be two. The two side magnets 222 may be arc-shaped and arranged around the central magnet 221. In some other examples, the number of side magnets 222 may also be one. The side magnet 222 may be ring-shaped. Exemplarily, the gap between the side magnets 222 and the central magnet 221 forms a magnetic gap in the magnetic circuit assembly 22.

[0202] For example, the central magnet 221 may be generally annular. It is understood that the central magnet 221 may have a second through-hole 2211. The second through-hole 2211 may extend through the central magnet 221 along its axial direction. The second through-hole 2211 may connect to the first through-hole 2410 of the second diaphragm 241, thereby communicating with the outside of the speaker 20.

[0203] In some embodiments, the magnetic circuit assembly 22 may further include a magnetically conductive element 223. The magnetically conductive element 223 may be made of a magnetically conductive material. Exemplarily, the magnetically conductive element 223 may include a main body portion 2231, a peripheral portion 2232, and a connecting portion 2233. The connecting portion 2233 may connect between the main body portion 2231 and the peripheral portion 2232, and the connecting portion 2233 is bent relative to the main body portion 2231 and the peripheral portion 2232. Exemplarily, the connecting portion 2233 may surround the outer periphery of the main body portion 2231, and the peripheral portion 2232 may be connected to the outer periphery of the connecting portion 2233. Exemplarily, Figure 19 The main body 2231, peripheral part 2232, and connecting part 2233 are schematically divided by dashed lines. For example, the main body 2231 of the magnetic conductor 223 may be provided with a third through hole 2234.

[0204] For example, a portion of the side magnet 222 may be located within the mounting groove 219 of the basin holder 21 and fixedly connected to the basin holder 21. The peripheral portion 2232 of the magnetic conductor 223 may be located on the side of the side magnet 222 facing away from the first diaphragm 231 and fixedly connected to the side magnet 222 and the basin holder 21. The main body portion 2231 of the magnetic conductor 223 may be located on the side of the center magnet 221 facing away from the second diaphragm 241 and fixedly connected to the center magnet 221. The third through hole 2234 of the magnetic conductor 223 may communicate with the second through hole 2211 of the center magnet 221.

[0205] It is understood that in this embodiment, the central magnet can be indirectly connected to the basin stand 21 via the magnetic conductor 223. In some other embodiments, the magnetic circuit assembly 22 may not include the magnetic conductor 223. The central magnet 221 can be fixedly connected to the basin stand 21 via structural components such as a bracket.

[0206] For example, the connecting portion 2233 of the magnetic conductor 223 can be located between the central magnet 221 and the side magnet 222, separating the gap between the central magnet 221 and the side magnet 222 into a first gap and a second gap. The first gap can form a first magnetic gap 22a of the magnetic circuit assembly 22. The second gap can form a second magnetic gap 22b of the magnetic circuit assembly 22. It is understood that the first magnetic gap 22a and the second magnetic gap 22b can be spaced apart.

[0207] Please continue reading. Figure 18 and Figure 19 In some embodiments, one end of the first voice coil 232 is fixedly connected to the first diaphragm 231, for example, one end of the first voice coil 232 may be fixedly connected to the vibrating part of the first diaphragm 231. The other end of the first voice coil 232 (that is, the end of the first voice coil 232 away from the first diaphragm 231) may be located in the first magnetic gap 22a of the magnetic circuit assembly 22.

[0208] For example, the first voice coil 232 may include two terminals, namely the first terminal 2321 (see [link]). Figure 3 ) and second wiring section 2322 (see Figure 3Both the first wiring portion 2321 and the second wiring portion 2322 can be led out from the main body of the first voice coil 232 and are located outside the main body of the first voice coil 232. The first wiring portion 2321 can be electrically connected to the first electrical connector 251, thereby connecting the first wiring portion 2321 to an external power source through the first electrical connector 251 and the second electrical connector 252. For example, the first wiring portion 2321 can be electrically connected to the positive terminal of the external power source. The second wiring portion 2322 can be electrically connected to the third electrical connector 261, thereby connecting the second wiring portion 2322 to an external power source through the third electrical connector 261 and the fourth electrical connector 262. For example, the second wiring portion 2322 can be electrically connected to the negative terminal of the external power source. In this way, the external power source can supply power to the first voice coil 232. Current can form a circuit between the first electrical connection assembly 25, the first voice coil 232, and the second electrical connection assembly 26.

[0209] In this embodiment, when the first voice coil 232 is energized, it generates a force in the magnetic field of the magnetic circuit assembly 22, thereby driving the first diaphragm 231 to vibrate. The first diaphragm 231 then drives the air to vibrate, thus enabling the speaker 20 to produce sound. The first voice coil 232 can receive alternating signals and generate alternating forces in the magnetic field.

[0210] In this embodiment, the second connecting portion 2524 of the second electrical connector 252 is spaced apart from the first diaphragm 231. The other end of the second electrical connector 252 may extend beyond the edge of the first diaphragm 231 and reach the side of the first diaphragm 231 facing away from the frame 21. For example, a portion of the first connecting portion 2523 of the second electrical connector 252 may extend beyond the edge of the first diaphragm 231, and the second connecting portion 2524 may be located on the side of the first diaphragm 231 away from the frame 21.

[0211] The second connecting portion 2624 of the fourth electrical connector 262 is spaced apart from the first diaphragm 231. The other end of the fourth electrical connector 262 may extend beyond the edge of the first diaphragm 231 and extend to the side of the first diaphragm 231 facing away from the frame 21. For example, a portion of the first connecting portion 2623 of the fourth electrical connector 262 may extend beyond the edge of the first diaphragm 231, and at least a portion of the second connecting portion 2624 may be located on the side of the first diaphragm 231 away from the frame 21.

[0212] The second connecting portion 2624 of the sixth electrical connector 272 is spaced apart from the first diaphragm 231. The other end of the sixth electrical connector 272 may extend beyond the edge of the first diaphragm 231 and extend to the side of the first diaphragm 231 facing away from the frame 21. For example, a portion of the first connecting portion 2723 of the sixth electrical connector 272 may extend beyond the edge of the first diaphragm 231, and at least a portion of the second connecting portion 2724 may be located on the side of the first diaphragm 231 away from the frame 21.

[0213] The second connecting portion 2824 of the eighth electrical connector 282 is spaced apart from the first diaphragm 231. The other end of the eighth electrical connector 282 may extend beyond the edge of the first diaphragm 231 and extend to the side of the first diaphragm 231 facing away from the frame 21. For example, a portion of the first connecting portion 2823 of the eighth electrical connector 282 may extend beyond the edge of the first diaphragm 231, and at least a portion of the second connecting portion 2824 may be located on the side of the first diaphragm 231 away from the frame 21.

[0214] Understandably, the maximum low-frequency output capability of speaker 20 depends on the maximum displacement volume (Vdmax) of the speaker diaphragm in one direction. The maximum low-frequency output capability of speaker 20 is positively correlated with Vdmax; increasing Vdmax can improve the maximum low-frequency output capability of speaker 20, thereby improving the sound quality of speaker 20. Furthermore, as shown by Vdmax = Sd * Xmax, the maximum displacement volume (Vdmax) of the speaker diaphragm in one direction is related to the effective radiation area (Sd) and the maximum amplitude (Xmax) of the diaphragm. Increasing Sd or Xmax can increase Vdmax, thereby improving the maximum low-frequency output capability of speaker 20.

[0215] In this embodiment, by placing the second electrical connector 252 of the first electrical connection assembly 25 on the outside of the frame 21, compared to the scheme where the second electrical connector 252 is embedded in the frame 21, the second electrical connector 252 in this embodiment does not occupy the internal space of the frame 21, allowing the diameter of the first diaphragm 231 to be larger, thereby allowing the total area of ​​the first diaphragm 231 to be larger, i.e., a larger Sd, which in turn can increase the maximum displacement volume (Vdmax) of the first diaphragm 231, enabling the speaker 20 to have better low-frequency maximum output capability. Similarly, by placing the fourth electrical connector 262 of the second electrical connection assembly 26, the sixth electrical connector 272 of the third electrical connection assembly 27, and the eighth electrical connector 282 of the fourth electrical connection assembly 28 on the outside of the frame 21, without occupying the internal space of the frame 21, the diameter of the first diaphragm 231 can be larger, thereby allowing the total area of ​​the first diaphragm 231 to be larger, and thus enabling the speaker 20 to have better low-frequency maximum output capability.

[0216] Secondly, by placing the second electrical connector 252 of the first electrical connection assembly 25 on the outside of the basin frame 21, the second electrical connector 252 can be indirectly fixedly connected to the basin frame 21 through the first electrical connector 251. Compared to the scheme where the second electrical connector 252 is embedded in the basin frame 21, the assembly between the second electrical connector 252 and the basin frame 21 is simpler, which helps to simplify the assembly process of the second electrical connector 252. Furthermore, the structure and molding process of the basin frame 21 are simpler, which helps to improve production efficiency and reduce costs. Similarly, by placing the fourth electrical connector 262 of the second electrical connection assembly 26, the sixth electrical connector 272 of the third electrical connection assembly 27, and the eighth electrical connector 282 of the fourth electrical connection assembly 28 on the outside of the basin frame 21, the assembly between the fourth electrical connector 262, the sixth electrical connector 272, and the eighth electrical connector 282 and the basin frame 21 is simpler, and the structure and molding process of the basin frame 21 are simpler, which helps to improve production efficiency and reduce costs.

[0217] In this embodiment, by disposing at least a portion of the second connecting portion 2524 of the second electrical connector 252 on the side of the first diaphragm 231 away from the frame 21, the second connecting portion 2524 of the second electrical connector 252 does not occupy excessive space in the circumferential direction of the speaker 20, which helps to reduce the circumferential size of the speaker 20 and thus facilitates the miniaturization of the speaker 20. Similarly, by disposing at least a portion of the second connecting portion 2624 of the fourth electrical connector 262, the second connecting portion 2724 of the sixth electrical connector 272, and the second connecting portion 2824 of the eighth electrical connector 282 on the side of the first diaphragm 231 away from the frame 21, the ends of the fourth electrical connector 262, the sixth electrical connector 272, and the eighth electrical connector 282 do not occupy excessive space in the circumferential direction of the speaker 20, which helps to reduce the circumferential size of the speaker 20 and thus facilitates the miniaturization of the speaker 20.

[0218] In some embodiments, one end of the second voice coil 242 is fixedly connected to the second diaphragm 241, for example, one end of the second voice coil 242 may be fixedly connected to the vibrating part 2411 of the second diaphragm 241. The other end of the second voice coil 242 (that is, the end of the second voice coil 242 away from the second diaphragm 241) may be located in the second magnetic gap 22b of the magnetic circuit assembly 22.

[0219] For example, the second voice coil 242 may include two terminals, namely a third terminal 2421 (see [link]). Figure 3 ) and fourth wiring section 2422 (see Figure 3Both the third terminal 2421 and the fourth terminal 2422 can be led out from the main body of the second voice coil 242 and are located outside the main body of the second voice coil 242. The third terminal 2421 can be electrically connected to the fifth electrical connector 271, thereby connecting the third terminal 2421 to an external power source via the fifth and sixth electrical connectors 271 and 272. For example, the third terminal 2421 can be electrically connected to the positive terminal of the external power source. The fourth terminal 2422 can be electrically connected to the seventh electrical connector 281, thereby connecting the fourth terminal 2422 to an external power source via the seventh and eighth electrical connectors 281 and 282. For example, the fourth terminal 2422 can be electrically connected to the negative terminal of the external power source. In this way, the external power source can supply power to the second voice coil 242. Current can form a circuit between the third electrical connection assembly 27, the second voice coil 242, and the fourth electrical connection assembly 28.

[0220] In this embodiment, when the second voice coil 242 is energized, it generates a force in the magnetic field of the magnetic circuit assembly 22, thereby driving the second diaphragm 241 to vibrate. The second diaphragm 241 then vibrates the air, thus enabling the speaker 20 to produce sound. The second voice coil 242 can receive alternating signals and generate alternating forces in the magnetic field.

[0221] In this embodiment, the sound generated by the first diaphragm 231 can propagate through the third through-hole 2234 of the magnetic conductor 223 of the magnetic circuit assembly 22, the second through-hole 2211 of the central magnet 221, and the first through-hole 2410 of the second diaphragm 241 to the side of the second diaphragm 241 opposite to the first diaphragm 231. The sound generated by the second diaphragm 241 can also propagate to the side of the second diaphragm 241 opposite to the first diaphragm 231. It is understood that the sound generated by the first diaphragm 231 and the sound generated by the second diaphragm 241 can form a sound field superposition on the side of the second diaphragm 241 opposite to the first diaphragm 231, thereby improving the sound quality of the speaker 20.

[0222] It is understood that, in the embodiments of this application, the external power supply for powering the first voice coil 232 and the external power supply for powering the second voice coil 242 can be different power supplies. Thus, the first voice coil 232 and the second voice coil 242 can be controlled by different circuits, allowing them to operate independently, thereby driving the first diaphragm 231 and the second diaphragm 241 to vibrate independently, respectively. In some other embodiments, the external power supply for powering the first voice coil 232 and the external power supply for powering the second voice coil 242 can also be the same power supply; this application does not strictly limit this.

[0224] In some embodiments, the housing 29 may include a housing portion 291 and a fixing portion 292. The housing portion 291 is fixedly connected to the fixing portion 292.

Figure 23 yes Figure 22A The diagram shows a partial cross-sectional view of the fixing part 292 of the housing 29 cut along GG.

[0226] In some embodiments, the fixing portion 292 of the housing 29 may include a first surface 2923, a second surface 2924, and a third surface 2925. The first surface 2923 and the second surface 2924 may be disposed opposite to each other in the axial direction of the speaker 20. The third surface 2925 is connected to the first surface 2923 and spaced apart from the second surface 2924. It is understood that the third surface 2925 and the first surface 2923 may be disposed at an angle. For example, the angle between the third surface 2925 and the first surface 2923 may be an obtuse angle. In other embodiments, the third surface 2925 may also be connected between the first surface 2923 and the second surface 2924. This application does not impose strict limitations on this.

[0227] For example, the fixing portion 292 of the housing 29 may be provided with a first through hole 2926, a second through hole 2927, a third through hole 2928, and a fourth through hole 2929 spaced apart. One end of the first through hole 2926 may be located on the third surface 2925 of the housing 29, and the other end may be located on the second surface 2924 of the housing 29. For example, the first through hole 2926 may be curved. The other end of the first through hole 2926 may be located at the edge of the second surface 2924. Similarly, one end of the second through hole 2927 may be located on the third surface 2925 of the housing 29, and the other end may be located on the second surface 2924 of the housing 29. For example, the second through hole 2927 may be curved. The other end of the second through hole 2927 may be located at the edge of the second surface 2924. In this embodiment, the structure of the second through hole 2927 may be the same as or similar to the structure of the first through hole 2926. The third through hole 2928 has one opening located on the third surface 2925 of the housing 29 and the other opening located on the second surface 2924 of the housing 29. Exemplarily, the third through hole 2928 can be curved. The other opening of the third through hole 2928 can be located at the edge of the second surface 2924. In this embodiment, the structure of the third through hole 2928 can be the same as or similar to the structure of the first through hole 2926. Similarly, the fourth through hole 2929 has one opening located on the third surface 2925 of the housing 29 and the other opening located on the second surface 2924 of the housing 29. Exemplarily, the fourth through hole 2929 can be curved. The other opening of the fourth through hole 2929 can be located at the edge of the second surface 2924. In this embodiment, the structure of the fourth through hole 2929 can be the same as or similar to the structure of the first through hole 2926.

[0228] In some embodiments, the fixing portion 292 of the housing 29 can be made of insulating materials such as plastic or rubber. In some examples, the shell portion 291 of the housing 29 can be made of metal materials such as steel, thereby giving the shell portion 291 better structural strength. In other examples, the shell portion 291 of the housing 29 can also be made of plastic, thereby making the housing 29 lighter and less expensive.

[0229] Please refer to the following: Figure 23 and Figure 24 , Figure 24 yes Figure 2 The speaker 20 shown is a schematic diagram of a partial cross-sectional structure cut along HH in some embodiments.

[0230] In some embodiments, the housing 29 is fixedly connected to the basin stand 21. Exemplarily, at least a portion of the first diaphragm 231 may be located between the housing 29 and the basin stand 21. It is understood that the first diaphragm 231 may be partially or entirely located between the housing 29 and the basin stand 21. The housing 29 may cover at least a portion of the first diaphragm 231 for protection. Exemplarily, the periphery of the housing 29 may be fixedly connected to the fixing portion 292 of the first diaphragm 231. For example, the edge of the shell portion 291 of the housing 29 may be fixedly connected to the fixing portion 292 of the first diaphragm 231, and the second surface 2924 of the fixing portion 292 of the housing 29 may be fixedly connected to the fixing portion 292 of the first diaphragm 231. It is understood that the housing 29 may be indirectly connected to the basin stand 21 via the first diaphragm 231.

[0231] In some embodiments, the first electrical connection assembly 25 is fixedly connected to the housing 29. Exemplarily, the second electrical connector 252 of the first electrical connection assembly 25 may pass through the fixing portion 292 of the housing 29. Exemplarily, a portion of the second connecting portion 2524 of the second electrical connector 252 may be located within the first through hole 2926 of the fixing portion 292 of the housing 29. For example, the first segment 2525 of the second connecting portion 2524 of the second electrical connector 252 may be located within the first through hole 2926, and a portion of the second segment 2526 may be located within the first through hole 2926.

[0232] In this embodiment, the first electrical connection assembly 25 is insulated from the fixing portion 292 of the housing 29. It is understood that the first electrical connection assembly 25 can be insulated from the speaker 20 or other components besides the speaker 20 via the fixing portion 292 of the housing 29, thereby reducing the risk of short circuits when the first electrical connection assembly 25 is electrically connected to an external power source.

[0233] For example, the other end of the second electrical connector 252 may also pass through the housing 29 and protrude relative to the housing 29. For instance, the second electrical connector 252 may pass through the first through hole 2926 of the fixing portion 292 of the housing 29, and the second segment 2526 of the second connecting portion 2524 of the second electrical connector 252 may protrude relative to the third surface 2925 of the fixing portion 292 for electrical connection to an external power source. In this case, the length extension direction of the second segment 2526 of the second electrical connector 252 is set at an angle to the axial direction of the speaker 20.

[0234] In some embodiments, the second electrical connection assembly 26 is fixedly connected to the housing 29. Exemplarily, the fourth electrical connector 262 of the second electrical connection assembly 26 may pass through the fixing portion 292 of the housing 29. For example, a portion of the fourth electrical connector 262 may be located within the second through-hole 2927 of the fixing portion 292 of the housing 29. The other end of the fourth electrical connector 262 may also pass through the housing 29 and protrude relative to the housing 29. For example, the fourth electrical connector 262 may pass through the second through-hole 2927 of the fixing portion 292 of the housing 29, and the end of the other end of the fourth electrical connector 262 may protrude relative to the third surface 2925 of the fixing portion 292 for electrical connection to an external power source. The second electrical connection assembly 26 is insulated from the fixing portion 292 of the housing 29. It is understood that the second electrical connection assembly 26 can be insulated from the speaker 20 or other components other than the speaker 20 through the fixing portion 292 of the housing 29, thereby reducing the risk of short circuit when the second electrical connection assembly 26 is electrically connected to an external power source.

[0235] Please refer to the following: Figure 23 and Figure 25 , Figure 25 yes Figure 2 The speaker 20 shown is a schematic diagram of a partial cross-sectional structure cut along the JJ in some embodiments.

[0236] In some embodiments, the third electrical connection assembly 27 is fixedly connected to the housing 29. Exemplarily, the sixth electrical connector 272 of the third electrical connection assembly 27 may pass through the fixing portion 292 of the housing 29. Exemplarily, a portion of the second connecting portion 2724 of the sixth electrical connector 272 may be located within the third through hole 2928 of the fixing portion 292 of the housing 29. For example, a first segment 2725 of the second connecting portion 2724 of the sixth electrical connector 272 may be located within the third through hole 2928, and a portion of the second segment 2726 may be located within the third through hole 2928.

[0237] In this embodiment, the third electrical connection component 27 is insulated from the fixing portion 292 of the housing 29. It is understood that the third electrical connection component 27 can be insulated from the speaker 20 or other components other than the speaker 20 through the fixing portion 292 of the housing 29, thereby reducing the risk of short circuit when the third electrical connection component 27 is electrically connected to an external power source.

[0238] For example, the other end of the sixth electrical connector 272 may also pass through the housing 29 and protrude relative to the housing 29. For instance, the sixth electrical connector 272 may pass through the third through-hole 2928 of the fixing portion 292 of the housing 29, and the second segment 2726 of the second connecting portion 2724 of the sixth electrical connector 272 may protrude relative to the third surface 2925 of the fixing portion 292 for electrical connection to an external power source. In this case, the length extension direction of the second segment of the sixth electrical connector 272 is set at an angle to the axial direction of the speaker 20.

[0239] In some embodiments, the fourth electrical connection assembly 28 is fixedly connected to the housing 29. Exemplarily, the eighth electrical connector 282 of the fourth electrical connection assembly 28 may pass through the fixing portion 292 of the housing 29. For example, a portion of the eighth electrical connector 282 may be located within the fourth through-hole 2929 of the fixing portion 292 of the housing 29. The other end of the eighth electrical connector 282 may also pass through the housing 29 and protrude relative to the housing 29. For example, the eighth electrical connector 282 may pass through the fourth through-hole 2929 of the fixing portion 292 of the housing 29, and the end of the other end of the eighth electrical connector 282 may protrude relative to the third surface 2925 of the fixing portion 292 for electrical connection to an external power source. The fourth electrical connection assembly 28 is insulated from the fixing portion 292 of the housing 29. It is understood that the fourth electrical connection assembly 28 can be insulated from the speaker 20 or other components other than the speaker 20 through the fixing portion 292 of the housing 29, thereby reducing the risk of short circuit when the fourth electrical connection assembly 28 is electrically connected to an external power source.

[0240] It is understandable that the second electrical connector 252 of the first electrical connection assembly 25, the fourth electrical connector 262 of the second electrical connection assembly 26, the sixth electrical connector 272 of the third electrical connection assembly 27, and the eighth electrical connector 282 of the fourth electrical connection assembly 28 can all be fixedly connected to the basin stand 21 through the fixing part 292 of the housing 29. This strengthens the connection between the second electrical connector 252 and the basin stand 21 and reduces the risk of the second electrical connector 252 falling off.

[0241] Please see Figures 26A to 27 , Figure 26A yes Figure 1 The diagram shown is a structural schematic of the speaker 20 in some other embodiments. Figure 26B yes Figure 26A The diagram shown is a partial structural schematic of the electronic device 100 in some embodiments. Figure 27 yes Figure 26A The diagram shows a schematic representation of the first electrical connection assembly 25 of the speaker 20 in some embodiments. For example, Figure 26AThe speaker 20 in the illustrated embodiment may include most of the technical content of the previous embodiment. The following mainly describes the differences between the two, and the most common aspects of the two will not be repeated.

[0242] In this embodiment, the first electrical connection assembly 25 may include a second electrical connector 252 and a first electrical connector 251. The second electrical connector 252 is located on one side of the first electrical connector 251 and is fixedly connected to the first electrical connector 251. The structure, material, and arrangement of the first electrical connector 251 can be the same as those in the previous embodiment.

The first connecting portion 2523 is connected to the second connecting portion 2524. The first connecting portion 2523 is fixedly connected to and electrically connected to the first electrical connector 251. For example, Figure 27 The first connecting portion 2523 and the second connecting portion 2524 of the second electrical connector 252 are schematically divided by dashed lines. For example, the second connecting portion 2524 may be located on one side of the first connecting portion 2523 along the length extension direction of the first connecting portion 2523.

[0244] In this embodiment, the second connecting portion 2524 may include a first segment 2525 and a second segment 2526. For example, Figure 27 The first segment 2525 and the second segment 2526 of the second electrical connector 252 are schematically distinguished by dashed lines. The first segment 2525 of the second electrical connector 252 can be connected between the second segment 2526 and the first connecting part 2523.

[0245] For example, the first segment 2525 of the second electrical connector 252 can be bent relative to the first connecting portion 2523, that is, the first segment 2525 of the second electrical connector 252 and the first connecting portion 2523 can be arranged at an angle. For example, the angle between the first segment 2525 of the second electrical connector 252 and the first connecting portion 2523 can be in the range of 0° to 180°.

[0246] For example, along the length extension direction of the first connecting portion 2523, at least a portion of the second segment 2526 of the second electrical connector 252 may be located on the side of the first segment 2525 away from the first connecting portion 2523. The second segment 2526 of the second electrical connector 252 may be bent relative to the first segment 2525, that is, the second segment 2526 of the second electrical connector 252 is set at an angle to the first segment 2525.

The angle between the first segment 2725 and the first connecting portion 2723 can be in the range of 0° to 180°.

[0254] For example, along the length extension direction of the first connecting portion 2723, at least a portion of the second segment 2726 may be located on the side of the first segment 2725 away from the first connecting portion 2723. The second segment 2726 of the sixth electrical connector 272 may be bent relative to the first segment 2725, that is, the second segment 2726 and the first segment 2725 are arranged at an angle. The angle between the second segment 2726 and the first segment 2725 may be in the range of 0° to 180°. For example, the length extension direction of the second segment 2726 of the sixth electrical connector 272 may be parallel to the length extension direction of the first connecting portion 2723.

[0255] In this embodiment, at least a portion of the first connecting portion 2723 of the sixth electrical connector 272 may be located outside the outer side 2133 of the frame 21. The first segment 2725 of the second connecting portion 2724 may be bent relative to the first connecting portion 2723 toward the first surface 2131 of the frame 21, and at least a portion of the second segment 2726 may be located on the side of the first diaphragm 231 facing away from the frame 21. Exemplarily, the extension lengths of the first connecting portion 2723 of the sixth electrical connector 272 and the second segment 2726 of the second connecting portion 2724 may both be parallel to the axial direction of the speaker 20.

[0256] It is understood that, in this embodiment, the structure and arrangement of the fourth electrical connection component 28 can be the same as... Figure 28 The structure and arrangement of the third electrical connection component 27 in the illustrated embodiment are the same or similar. For the technical solution of the fourth electrical connection component 28, please refer to [reference needed].

For example, Figure 29 The diagram mainly shows the assembly structure of the speaker 20 housing 29, the second electrical connector 252, the fourth electrical connector 262, the sixth electrical connector 272, and the eighth electrical connector 282.

[0258] In this embodiment, the fixing portion 292 of the housing 29 may include a first surface 2923, a second surface 2924, and a third surface 2925. The first surface 2923 and the second surface 2924 are disposed facing away from each other. The third surface 2925 is connected to the first surface 2923 and spaced apart from the second surface 2924. It is understood that the third surface 2925 and the first surface 2923 may be disposed at an angle. For example, the angle between the third surface 2925 and the first surface 2923 may be an obtuse angle. In some other embodiments, the third surface 2925 may also be connected between the first surface 2923 and the second surface 2924. This application does not impose strict limitations on this.

[0259] For example, the fixing portion 292 of the housing 29 may be provided with a first through hole 2926, a second through hole 2927, a third through hole 2928, and a fourth through hole 2929 spaced apart. One end of the first through hole 2926 may be located on the first surface 2923 of the housing 29, and the other end may be located on the second surface 2924 of the housing 29. For example, the first through hole 2926 may be curved. The other end of the first through hole 2926 may be located at the edge of the second surface 2924 away from the housing portion 291. Similarly, one end of the second through hole 2927 may be located on the first surface 2923 of the housing 29, and the other end may be located on the second surface 2924 of the housing 29. For example, the second through hole 2927 may be curved. The other end of the second through hole 2927 may be located at the edge of the second surface 2924 away from the housing portion 291. It is understood that the structure of the second through hole 2927 may be the same as or similar to the structure of the first through hole 2926. The third through hole 2928 has one opening located on the first surface 2923 of the housing 29 and the other opening located on the second surface 2924 of the housing 29. Exemplarily, the third through hole 2928 can be curved. The other opening of the third through hole 2928 can be located at the edge of the second surface 2924 away from the housing portion 291. It is understood that the structure of the third through hole 2928 can be the same as or similar to the structure of the first through hole 2926. Similarly, the fourth through hole 2929 has one opening located on the first surface 2923 of the housing 29 and the other opening located on the second surface 2924 of the housing 29. Exemplarily, the fourth through hole 2929 can be curved. The other opening of the fourth through hole 2929 can be located at the edge of the second surface 2924 away from the housing portion 291. It is understood that the structure of the fourth through hole 2929 can be the same as or similar to the structure of the first through hole 2926.

[0260] Understandable, Figure 29 The fixing part 292 of the housing 29 shown above is the same as the above. Figure 22A The structure of the fixing part 292 of the housing 29 shown is similar, except that the opening positions of the first through hole 2926, the second through hole 2927, the third through hole 2928 and the fourth through hole 2929 are set differently.

[0261] In some embodiments, the first electrical connection assembly 25 is fixedly connected to the housing 29. A second electrical connection member 252 may pass through the fixing portion 292 of the housing 29. For example, a portion of the second electrical connection member 252 may be located within a first through-hole 2926 of the fixing portion 292 of the housing 29. The first electrical connection assembly 25 is insulated from the fixing portion 292 of the housing 29.

[0262] For example, the other end of the second electrical connector 252 may also pass through the housing 29 and protrude relative to the housing 29. For instance, the second electrical connector 252 may pass through the first through hole 2926 of the fixing portion 292 of the housing 29, and the second segment 2526 of the second electrical connector 252 may protrude relative to the first surface 2923 of the fixing portion 292 for electrical connection to an external power source. The length extension direction of the second segment 2526 of the second electrical connector 252 may be parallel to the axial direction of the speaker 20. It is understood that, in this embodiment, the shape and opening position of the first through hole 2926 of the fixing portion 292 of the housing 29 can be adjusted according to the shape of the second connecting portion 2524 of the second electrical connector 252 to adapt to the shape of the second connecting portion 2524 of the second electrical connector 252.

[0263] In some embodiments, the second electrical connection assembly 26 is fixedly connected to the housing 29. A fourth electrical connection member 262 may pass through the fixing portion 292 of the housing 29. For example, a portion of the fourth electrical connection member 262 may be located within the second through hole 2927 of the fixing portion 292 of the housing 29. The second electrical connection assembly 26 is insulated from the fixing portion 292 of the housing 29.

[0264] For example, the other end of the fourth electrical connector 262 may also pass through the housing 29 and protrude relative to the housing 29. For instance, the fourth electrical connector 262 may pass through the second through hole 2927 of the fixing portion 292 of the housing 29, and the second segment 2626 of the fourth electrical connector 262 may protrude relative to the first surface 2923 of the fixing portion 292 for electrical connection to an external power source. The length extension direction of the second segment 2626 of the fourth electrical connector 262 may be parallel to the axial direction of the speaker 20. It is understood that, in this embodiment, the shape and opening position of the second through hole 2927 of the fixing portion 292 of the housing 29 can be adjusted according to the shape of the second connecting portion 2624 of the fourth electrical connector 262 to adapt to the shape of the second connecting portion 2624 of the fourth electrical connector 262.

[0265] In some embodiments, the third electrical connection assembly 27 is fixedly connected to the housing 29. The sixth electrical connection member 272 may pass through the fixing portion 292 of the housing 29. For example, a portion of the sixth electrical connection member 272 may be located within the third through hole 2928 of the fixing portion 292 of the housing 29. The third electrical connection assembly 27 is insulated from the fixing portion 292 of the housing 29.

[0266] For example, the other end of the sixth electrical connector 272 may also pass through the housing 29 and protrude relative to the housing 29. For instance, the sixth electrical connector 272 may pass through the third through-hole 2928 of the fixing portion 292 of the housing 29, and the second segment 2726 of the sixth electrical connector 272 may protrude relative to the first surface 2923 of the fixing portion 292 for electrical connection to an external power source. The length extension direction of the second segment 2726 of the sixth electrical connector 272 may be parallel to the axial direction of the speaker 20. It is understood that, in this embodiment, the shape and opening position of the third through-hole 2928 of the fixing portion 292 of the housing 29 can be adjusted according to the shape of the second connecting portion 2724 of the sixth electrical connector 272 to adapt to the shape of the second connecting portion 2724 of the sixth electrical connector 272.

[0267] In some embodiments, the fourth electrical connection assembly 28 is fixedly connected to the housing 29. Exemplarily, the eighth electrical connector 282 of the fourth electrical connection assembly 28 may pass through the fixing portion 292 of the housing 29. For example, a portion of the eighth electrical connector 282 may be located within the fourth through hole 2929 of the fixing portion 292 of the housing 29. The fourth electrical connection assembly 28 is insulated from the fixing portion 292 of the housing 29.

[0268] For example, the other end of the eighth electrical connector 282 may also pass through the housing 29 and protrude relative to the housing 29. For instance, the eighth electrical connector 282 may pass through the fourth through hole 2929 of the fixing portion 292 of the housing 29, and the second segment 2826 of the eighth electrical connector 282 may protrude relative to the first surface 2923 of the fixing portion 292 for electrical connection to an external power source. The length extension direction of the second segment 2826 of the eighth electrical connector 282 may be parallel to the axial direction of the speaker 20. It is understood that, in this embodiment, the shape and opening position of the fourth through hole 2929 of the fixing portion 292 of the housing 29 can be adjusted according to the shape of the second connecting portion 2824 of the eighth electrical connector 282 to adapt to the shape of the second connecting portion 2824 of the eighth electrical connector 282.

[0269] In this embodiment, by placing the second connecting portion 2524 of the second electrical connector 252 on the side of the first diaphragm 231 away from the frame 21, the second connecting portion 2524 of the second electrical connector 252 does not occupy excessive space in the circumferential direction of the speaker 20, which helps to reduce the circumferential size of the speaker 20 and thus facilitates the miniaturization of the speaker 20. Similarly, by placing the second connecting portions 2624 of the fourth electrical connector 262, the second connecting portions 2724 of the sixth electrical connector 272, and the second connecting portions 2824 of the eighth electrical connector 282 on the side of the first diaphragm 231 away from the frame 21, the second connecting portions 2624 of the fourth electrical connector 262, the second connecting portions 2724 of the sixth electrical connector 272, and the second connecting portions 2824 of the eighth electrical connector 282 do not occupy excessive space in the circumferential direction of the speaker 20, which helps to reduce the circumferential size of the speaker 20 and thus facilitates the miniaturization of the speaker 20.

[0270] Please see Figure 30 and Figure 31 , Figure 30 yes Figure 1 The diagram shown is a structural schematic of the speaker 20 in some other embodiments. Figure 31 yes Figure 30 The diagram shows a schematic representation of the first electrical connection assembly 25 of the speaker 20 in some embodiments. For example, Figure 30 The speaker 20 in the illustrated embodiment may include most of the technical content of the previous embodiment. The following mainly describes the differences between the two, and the most common aspects of the two will not be repeated.

[0271] In this embodiment, the first electrical connection assembly 25 may include a second electrical connector 252 and a first electrical connector 251. The second electrical connector 252 is located on one side of the first electrical connector 251 and is fixedly connected to the first electrical connector 251. The structure, material, and arrangement of the first electrical connector 251 can be the same as those in the previous embodiment. The structure, material, and arrangement of the first electrical connector 251 in this embodiment can be found in the relevant solutions for the structure, material, and arrangement of the first electrical connector 251 in the previous embodiment. Specific details will not be elaborated here.

[0272] The second electrical connector 252 may include a first lead 2527 and a first solder pin 2528. The first solder pin 2528 may be located on the side of the first diaphragm 231 facing away from the frame 21 and is fixedly connected to the frame 21. In this embodiment, by placing the first solder pin 2528 of the second electrical connector 252 on the side of the first diaphragm 231 away from the frame 21, the first solder pin 2528 of the second electrical connector 252 does not occupy excessive space in the circumferential direction of the speaker 20, which helps to reduce the circumferential size of the speaker 20 and thus facilitates the miniaturization of the speaker 20.

[0273] In this embodiment, the structure and material of the first welding pin 2528 can be the same as those of the second segment 2526 of the second connecting portion 2524 of the second electrical connector 252. The basic design of the structure of the first welding pin 2528 and its connection relationship with other structures can be found in the relevant schemes for the second segment 2526 of the second connecting portion 2524 of the second electrical connector 252. At the same time, slight differences in the detailed structure or positional arrangement of the components are allowed between the first welding pin 2528 and the second segment 2526 of the second connecting portion 2524 of the second electrical connector 252. Specific details will not be elaborated here. In other embodiments, the first welding pin 2528 and the second segment 2526 of the second connecting portion 2524 of the second electrical connector 252 can also be similar, symmetrical, partially symmetrical, or different structures. This application does not impose strict limitations on these aspects.

[0274] At least a portion of the first lead 2527 can be located outside the outer surface 2133 of the basin frame 21. One end of the first lead 2527 can be fixedly connected to and electrically connected to the first welding pin 2528, and the other end can be fixedly connected to and electrically connected to the first electrical connector 251. It is understood that the first lead 2527 is a flexible component and can deform. Using a lead to achieve the electrical connection between the first welding pin 2528 and the first electrical connector 251, compared to a solution using a rigid component to connect the first welding pin 2528 and the first electrical connector 251, the positions of the first welding pin 2528 and the first electrical connector 251 in this embodiment are less likely to be restricted by each other. That is, the positions of the first welding pin 2528 and the first electrical connector 251 can be adjusted as needed, making the position settings of the first welding pin 2528 and the first electrical connector 251 more flexible, thus broadening the applicability of the first electrical connection assembly 25. For example, the material of the first lead can be conductive metals such as copper, silver, or gold.

[0275] In some examples, the first lead 2527 can be a three-dimensional (3D) printed lead, meaning it can be manufactured using 3D printing technology. Understandably, the first lead 2527 can be 3D printed to connect between the first electrical connector 251 and the first solder pin 2528, which improves the strength and reliability of the connection between the first lead 2527 and the first electrical connector 251 and the first solder pin 2528. In other examples, the first lead can also be a cable. In this case, the first lead 2527 can also be fixedly connected and electrically connected to the first connecting surface of the first electrical connector 251 by metal welding. Understandably, metal welding can include, but is not limited to, laser welding and soldering.

[0276] In some embodiments, the diameter of the first lead 2527 is less than or equal to 0.1 mm. In this way, the first lead 2527 occupies less space in the circumferential direction of the speaker 20, which is beneficial to reducing the circumferential size of the speaker 20, and thus to miniaturizing the speaker 20.

[0277] In this embodiment, the second electrical connection assembly 26 may include a third electrical connector 261 and a fourth electrical connector 262. The fourth electrical connector 262 may include a second lead 2627 and a second solder pin 2628. For example, the second solder pin 2628 may be located on the side of the first diaphragm 231 facing away from the frame 21 and fixedly connected to the frame 21. In this way, the second solder pin 2628 of the fourth electrical connector 262 will not occupy excessive space in the circumferential direction of the speaker 20, which is beneficial for reducing the circumferential size of the speaker 20 and thus facilitating the miniaturization of the speaker 20.

[0278] For example, at least a portion of the second lead 2627 may be located outside the outer surface 2133 of the basin frame 21. One end of the second lead 2627 may be fixedly connected to and electrically connected to the second solder pin 2628, and the other end may be fixedly connected to and electrically connected to the third electrical connector 261. In this way, the positions of the second solder pin 2628 and the third electrical connector 261 are no longer restricted by each other, making the positional arrangement of the second solder pin 2628 and the third electrical connector 261 more flexible, thereby broadening the applicability of the second electrical connection assembly 26.

[0279] It is understandable that the structure and materials of the second electrical connection assembly 26 can be the same as those of the second electrical connection assembly 26. Figure 30 and Figure 31 The first electrical connection assembly 25 shown has the same structure and materials. For the basic design of the component structure of the second electrical connection assembly 26, the design of the connection relationships between components, and the design of the connection relationships between components and other structures outside the assembly, please refer to [reference needed]. Figure 30 and Figure 31The diagram illustrates the relevant scheme for the first electrical connection assembly 25. It also allows for slight differences in the detailed structure or positional arrangement of the second electrical connection assembly 26 compared to the first electrical connection assembly 25. Specific details will not be elaborated here. In some other embodiments, the second electrical connection assembly 26 and... Figure 30 and Figure 31 The first electrical connection component 25 shown may also be a similar structure, a symmetrical or partially symmetrical structure, or a different structure. This application does not impose strict limitations on this.

[0280] In this embodiment, the third electrical connection assembly 27 may include a sixth electrical connector 272 and a fifth electrical connector 271. The sixth electrical connector 272 may include a third lead 2727 and a third solder pin 2728. For example, the third solder pin 2728 may be located on the side of the first diaphragm 231 facing away from the frame 21 and fixedly connected to the frame 21. In this way, the third solder pin 2728 of the sixth electrical connector 272 will not occupy excessive space in the circumferential direction of the speaker 20, which is beneficial for reducing the circumferential size of the speaker 20 and thus facilitating the miniaturization of the speaker 20.

[0281] For example, at least a portion of the third lead 2727 may be located outside the outer surface 2133 of the basin frame 21. One end of the third lead 2727 may be fixedly connected to and electrically connected to the third solder pin 2728, and the other end may be fixedly connected to and electrically connected to the fifth electrical connector 271. In this way, the positions of the third solder pin 2728 and the fifth electrical connector 271 are no longer restricted by each other, making the positional arrangement of the third solder pin 2728 and the fifth electrical connector 271 more flexible, thereby broadening the applicability of the third electrical connection assembly 27.

[0282] It is understandable that the structure and materials of the third electrical connection assembly 27 can be compatible with... Figure 30 and Figure 31 The first electrical connection assembly 25 shown has the same structure and materials. For the basic design of the component structure of the third electrical connection assembly 27, the design of the connection relationships between components, and the design of the connection relationships between components and other structures outside the assembly, please refer to [reference needed]. Figure 30 and Figure 31 The diagram illustrates the relevant scheme of the first electrical connection component 25. It also allows for slight differences in the detailed structure or positional arrangement of the third electrical connection component 27 compared to the first electrical connection component 25. Specific details will not be elaborated here. In some other embodiments, the third electrical connection component 27 and... Figure 30 and Figure 31 The first electrical connection component 25 shown may also be a similar structure, a symmetrical or partially symmetrical structure, or a different structure. This application does not impose strict limitations on this.

[0283] In this embodiment, the fourth electrical connection assembly 28 may include an eighth electrical connector 282 and a seventh electrical connector 281. The eighth electrical connector 282 may include a fourth lead 2827 and a fourth solder pin 2828. For example, the fourth solder pin 2828 may be located on the side of the first diaphragm 231 facing away from the frame 21 and fixedly connected to the frame 21. In this way, the fourth solder pin 2828 of the eighth electrical connector 282 will not occupy excessive space in the circumferential direction of the speaker 20, which is beneficial for reducing the circumferential size of the speaker 20 and thus facilitating the miniaturization of the speaker 20.

[0284] For example, at least a portion of the fourth lead 2827 may be located outside the outer surface 2133 of the frame 21. One end of the fourth lead 2827 may be fixedly connected to and electrically connected to the fourth solder pin 2828, and the other end may be fixedly connected to and electrically connected to the seventh electrical connector 281. In this way, the positions of the fourth solder pin 2828 and the seventh electrical connector 281 are no longer restricted by each other, making the positional arrangement of the fourth solder pin 2828 and the seventh electrical connector 281 more flexible, thereby broadening the applicability of the fourth electrical connection assembly 28.

Figure 34 yes Figure 32 The diagram shows a partial cross-sectional view of the electronic device 100 shown, taken along line LL in some embodiments. It is understood that... Figure 33 The electronic device 100 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 33 Limited by.

[0288] In some embodiments, the electronic device 100 may include a housing 10, a speaker 20, a first circuit board 40, and a second circuit board 80. The housing 10 may be the housing 10 described above. The first circuit board 40 may be the first circuit board 40 described above. In some examples, the first circuit board 40 may have a microcontroller unit (not shown). The second circuit board 80 may be a flexible circuit board.

[0289] In some embodiments, the housing 10 of the electronic device 100 may include a front housing 11 and a rear housing 12. The front housing 11 is fixedly connected to the rear housing 12, and the front housing 11 and the rear housing 12 can together enclose an internal space 13. For example, the sound outlet 101 of the electronic device 100 may be located on the front housing 11 and communicate with the internal space 13. For example, Figure 34 The diagram mainly shows a partial cross-sectional structural schematic of the outer shell 10.

[0290] For example, the rear housing 12 may include a mounting space 121. The mounting space 121 may be disposed opposite to the internal space 13 of the housing 10. For example, the rear housing 12 may be provided with a communication hole 122. The communication hole 122 may connect the mounting space 121 and the internal space 13. For example, the housing 10 may be provided with an opening 123. The opening 123 of the housing 10 may be located in the rear housing 12. The opening 123 may connect to the mounting space 121. It is understood that in some examples, the opening 123 of the housing 10 may face the earpiece 30 of the electronic device 100 and connect to the earpiece 30 (see [link to documentation]). Figure 1 The internal space of ).

[0291] Please refer to the following: Figures 33 to 35 , Figure 35 yes Figure 33 The diagram shows an assembly structure of the rear shell 12 and the first circuit board 40 in some embodiments.

[0292] In some embodiments, the first circuit board 40 may be fixedly connected to the housing 10. Exemplarily, the first circuit board 40 may be located in the mounting space 121 and fixedly connected to the rear housing 12. For example, the first circuit board 40 may be fixedly connected to the rear housing 12 by adhesive or by fasteners such as bolts or studs. Exemplarily, the first circuit board 40 may cover the communication hole 122 of the rear housing 12. It is understood that a portion of the first circuit board 40 may be exposed relative to the communication hole 122.

[0293] For example, the first circuit board 40 may be exposed relative to the opening 123 of the rear cover 12. It is understood that the first circuit board 40 may be connected to other components of the electronic device 100 through the opening 123 of the rear cover 12. For example, the first circuit board 40 may be electrically connected to the power supply 50 inside the ear stem 30 through the opening 123 of the rear cover 12.

[0294] Please refer to the following: Figure 33 and Figure 36 , Figure 36 yes Figure 33 The diagram shows the assembly structure of the front housing 11 and the second circuit board 80 in some embodiments.

[0295] In some embodiments, the second circuit board 80 may be mounted in the internal space 13. Exemplarily, the second circuit board 80 may be fixedly connected to the housing 10. For example, the second circuit board 80 may be fixedly connected to the front housing 11.

[0296] For example, the second circuit board 80 may include a first portion 81, a second portion 82, and a third portion 83 connected in sequence. For example, the first portion 81, the second portion 82, and the third portion 83 of the second circuit board 80 may together enclose a receiving space 84. For example, Figure 36 The diagram uses dashed lines to exemplarily divide the second circuit board 80 into a first part 81, a second part 82, and a third part 83. The first part 81 of the second circuit board 80 can be fixedly connected to the front shell 11 of the outer casing 10. The second part 82 of the second circuit board 80 can be approximately arc-shaped. The second part 82 of the second circuit board 80 can have a first connecting hole 821, a second connecting hole 822, a third connecting hole 823, and a fourth connecting hole 824 spaced apart. All four connecting holes 821, 822, 823, and 824 can penetrate the third part 83 of the second circuit board 80.

[0297] Please refer to the following: Figures 36 to 38 , Figure 37 yes Figure 33 The diagram shown illustrates the assembly structure of the front housing 11, speaker 20, and second circuit board 80 in some embodiments. Figure 38 yes Figure 32The diagram shows a partial cross-sectional view of the electronic device 100 shown in some embodiments, cut along the MM line.

[0298] In some embodiments, the speaker 20 may be installed in the internal space 13. Exemplarily, the speaker 20 may be fixedly connected to the housing 10. For example, the speaker 20 may be fixedly connected to the front housing 11. Exemplarily, the speaker 20 may be fixedly connected to the housing 10 by adhesive dispensing. The speaker 20 and the front housing 11 may together enclose a sound outlet chamber 14. The sound outlet chamber 14 may communicate with the sound outlet 101 of the electronic device 100.

[0299] For example, the second diaphragm 241 of the speaker 20 may face the sound outlet 101 of the housing 10. The sound outlet chamber 14 may communicate with the side of the first diaphragm 231 near the frame 21, so that the sound outlet 101 may communicate with the space of the side of the first diaphragm 231 near the frame 21. The sound generated by the first diaphragm 231 and the second diaphragm 241 of the speaker 20 may be propagated to the outside of the electronic device 100 through the sound outlet 101.

[0300] In some embodiments, at least a portion of the speaker 20 may be located within the receiving space 84 of the second circuit board 80. Exemplarily, a second portion 82 of the second circuit board 80 may surround the speaker 20. The first electrical connection assembly 25 of the speaker 20 may be fixedly connected to and electrically connected to the second circuit board 80. Exemplarily, a second electrical connector 252 of the first electrical connection assembly 25 may pass through a first connection hole 821 of the second circuit board 80 and extend from the side of the second circuit board 80 opposite to the mounting space 121. For example, a second segment of the second electrical connector 252 may pass through the first connection hole 821 of the second circuit board 80. In this case, the end of the second electrical connector 252 may face the first circuit board 40.

[0301] The second electrical connection assembly 26 of the speaker 20 can be fixedly connected to and electrically connected to the second circuit board 80. For example, the fourth electrical connector 262 of the second electrical connection assembly 26 can pass through the second connection hole 822 of the second circuit board 80 and extend from the side of the second circuit board 80 facing away from the mounting space 121. In this case, the end of the fourth electrical connector 262 can face the first circuit board 40.

[0302] The third electrical connection assembly 27 of the speaker 20 can be fixedly connected to and electrically connected to the second circuit board 80. For example, the sixth electrical connector 272 of the third electrical connection assembly 27 can pass through the third connection hole 823 of the second circuit board 80 and extend from the side of the second circuit board 80 facing away from the mounting space 121. In this case, the end of the sixth electrical connector 272 can face the first circuit board 40.

[0303] The fourth electrical connection assembly 28 of the speaker 20 can be fixedly connected to and electrically connected to the second circuit board 80. For example, the second electrical connector 252 of the fourth electrical connection assembly 28 can pass through the fourth connection hole 824 of the second circuit board 80 and extend from the side of the second circuit board 80 facing away from the mounting space 121. In this case, the end of the second electrical connector 252 can face the first circuit board 40.

[0304] For example, the third portion 83 of the second circuit board 80 may be located on the side of the first diaphragm 231 of the speaker 20 that is away from the second diaphragm 241. For instance, the third portion 83 of the second circuit board 80 may be located on the side of the housing 29 of the speaker 20 that is away from the first diaphragm 231. In this case, the third portion 83 of the second circuit board 80 may be located between the first circuit board 40 and the speaker 20.

[0305] For example, a third portion 83 of the second circuit board 80 may pass through the through hole 122, and a portion of the third portion 83 may be located in the mounting space 121. The third portion 83 of the second circuit board 80 may be fixedly connected to and electrically connected to the first circuit board 40.

[0306] In this embodiment, the first electrical connection component 25, the second electrical connection component 26, the third electrical connection component 27, and the fourth electrical connection component 28 of the speaker 20 can be electrically connected to the first circuit board 40 via the second circuit board 80, thereby enabling electrical connection to other components of the electronic device 100 via the first circuit board 40. For example, the speaker 20 can be connected to the power supply 50 (see [link to application]) via the second circuit board 80 and the first circuit board 40. Figure 1 The power supply 50 can supply power to the speaker 20 through an electrical connection. In addition, the microcontroller unit (not shown) on the first circuit board 40 can also be used to control the state of the current, thereby controlling the vibration frequency of the first diaphragm 231 and the second diaphragm 241.

[0307] It is understood that in this embodiment, the outer casing 10 has a larger inner diameter, i.e., a larger space, located away from the sound outlet 101. This embodiment places the third portion 83 of the second circuit board 80 on the side of the speaker 20 away from the sound outlet 101, allowing the connection points between the second circuit board 80 and the first electrical connection components 25, 26, 27, and 28 of the speaker 20 to be located on the side of the speaker 20 away from the sound outlet 101. This provides a larger assembly space for the second circuit board 80 and the first electrical connection components 25, 26, 27, and 28 of the speaker 20, reducing the assembly difficulty between the speaker 20 and the second circuit board 80.

[0308] Furthermore, in this embodiment, the third portion 83 of the second circuit board 80 can be located between the first circuit board 40 and the speaker 20, and directly electrically connected to the first circuit board 40. This eliminates the need for additional electrical connection structures on the side of the first diaphragm 231 of the speaker 20 away from the frame 21 to achieve circuit connectivity between the second circuit board 80 and the first circuit board 40. This reduces the stacking space of components along the speaker 20 axis of the electronic device 100, thereby reducing the axial size of the electronic device 100 and facilitating miniaturization.

[0309] It is understood that, in the embodiments of this application, the length extension directions of the second segment 2526 of the second electrical connector 252, the second segment 2626 of the fourth electrical connector 262, the second segment 2726 of the sixth electrical connector 272, and the second segment 2826 of the eighth electrical connector 282 can all extend toward the outer periphery of the speaker 20. Thus, the space on the side of the first diaphragm 231 (or housing 29) of the speaker 20 away from the frame 21 can be used to house other components of the electronic device 100. That is, the speaker 20 can be used to avoid other components located in the internal space 13 and avoid interference with other components inside the electronic device 100.

[0310] In some other embodiments, the length extension directions of the second segment 2526 of the second electrical connector 252, the second segment 2626 of the fourth electrical connector 262, the second segment 2726 of the sixth electrical connector 272, and the second segment 2826 of the eighth electrical connector 282 are all parallel to the axial direction of the speaker 20. For example, the electronic device 100 may include... Figure 26A The speaker 20 is shown. At this time, the second segment 2526 of the second electrical connector 252 can be located entirely on the side of the first diaphragm 231 (or housing 29) away from the frame 21, without occupying the circumferential space of the speaker 30. Thus, when the speaker 30 is installed in the internal space 13 of the electronic device 100, the space on the outer periphery of the speaker 20 can be used to install other components of the electronic device 100. That is, the speaker 20 can be used to avoid other components located in the internal space 13, and avoid interference with other components inside the electronic device 100.

[0311] It is understandable that the arrangement of the second segment 2526 of the second electrical connector 252, the second segment 2626 of the fourth electrical connector 262, the second segment 2726 of the sixth electrical connector 272, and the second segment 2826 of the eighth electrical connector 282 of the speaker 20 can be determined according to the specific location of the speaker 20 within the internal space 13 and the component layout requirements of the electronic device 100, so as to avoid interference with other components within the internal space 13.

[0312] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0313] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
