Description

Technical Field

[0001] The present disclosure relates to the field of electronic technology, and in particular to an electronic device. Background Art

[0002] With the rapid iteration of electronic devices, their functions are becoming more and more abundant, their performance is becoming more and more extreme, and people's performance requirements for electronic devices in multiple scenarios are also getting higher and higher. Take mobile phones as an example. In the era of mobile Internet, voice calls, videos, audio and video entertainment, and games have become people's daily use of mobile phones, so the requirements for mobile phone audio performance are also more extreme.

[0003] In related technologies, increasing the volume of the speaker's rear cavity can effectively enhance the low-frequency component and achieve a more shocking audio experience. However, it also means squeezing the stacking space of mobile phones, resulting in problems such as increased mobile phone thickness and reduced battery capacity, affecting the user experience of the mobile phone. Summary of the invention

[0004] In view of this, the present disclosure provides an electronic device that can improve the audio experience without increasing the space occupied by the stacking of the electronic device, thereby improving the user experience of the electronic device.

[0005] Specifically, the present disclosure is implemented through the following technical solutions.

[0006] According to a first aspect of an embodiment of the present disclosure, there is provided an electronic device, comprising a housing assembly, a transmission assembly, a speaker module and a drive coil. The housing assembly is provided with a housing cavity. The transmission assembly is arranged in the housing cavity, and the transmission assembly is transmission-connected to the housing assembly so that the transmission assembly can move in the housing cavity. The transmission assembly is provided with a first magnetic body. The speaker module is rotationally connected to the transmission assembly and moves in the housing cavity with the transmission assembly so as to have an initial state in which the speaker module is accommodated in the housing cavity and an extended state in which at least part of the speaker module extends out of the housing cavity. The speaker module comprises a second magnetic body. Among them, one of the first magnetic body and the second magnetic body is wound with a drive coil, and the other cooperates with the drive coil so that the first magnetic body rotates relative to the second magnetic body and drives the transmission assembly to move in the housing cavity, so that the speaker module can switch between the initial state and the extended state.

The transmission assembly is arranged in the accommodating cavity of the shell assembly, and is connected to the shell assembly in a transmission manner, so that the transmission assembly can move in the accommodating cavity. The speaker module is rotatably connected to the transmission assembly, so that when the transmission assembly moves in the accommodating cavity, the speaker module can also move in the accommodating cavity together. Thus, the speaker module has an initial state of being accommodated in the accommodating cavity and an extended state of at least partially extending out of the accommodating cavity. When it is necessary to improve the audio experience, the speaker module is in an extended state. At this time, at least part of the speaker module extends out of the accommodating cavity, so that the volume of the rear cavity of the speaker module is increased, thereby enhancing the low-frequency component of the speaker module to achieve a more shocking audio experience.

[0041] In order to make the purpose, technical solution and advantages of this application more clear, the following is a further detailed description of this application in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain this application and do not limit the scope of protection of this application.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0043] With the rapid iteration of electronic devices, the functions of electronic devices are becoming more and more abundant, and the performance is becoming more and more extreme. People's performance requirements for electronic devices in multiple scenarios are also getting higher and higher. In the era of mobile Internet, voice calls, videos, audio and video entertainment, and games have become daily use of electronic devices, so the audio performance requirements of electronic devices are also more extreme. At present, there are many types and brands of electronic devices, which means that there are many electronic devices for consumers to choose from. How to win the favor of consumers and improve product competitiveness has become an issue that electronic equipment manufacturers are paying more and more attention to.

[0044] In the related art, by increasing the volume of the speaker back cavity, the low-frequency component can be effectively improved to achieve a more shocking audio experience. However, it also means squeezing the stacking space inside the electronic device, which leads to problems such as increased thickness of the electronic device and reduced battery capacity, affecting the user experience of the electronic device.

[0045] Based on this, the present disclosure provides an electronic device 10, which can improve the audio experience without increasing the space occupied by the stacking of the electronic device 10, thereby improving the user experience of the electronic device 10. The electronic device 10 can be an electronic product with a housing and sound playback function, such as a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. The wearable device can be a smart bracelet, a smart watch, a smart head display, smart glasses, etc.

[0046] like Figures 1 to 6 As shown, an embodiment of the present disclosure provides an electronic device 10 including a transmission assembly 100, a housing assembly 200, a speaker module 300 and a driving coil 400. The housing assembly 200 is provided with a receiving cavity 210. The transmission assembly 100 is disposed in the receiving cavity 210, and the transmission assembly 100 is transmission-connected with the housing assembly 200 so that the transmission assembly 100 can move in the receiving cavity 210. The transmission assembly 100 is provided with a first magnetic body 110. The speaker module 300 is rotationally connected with the transmission assembly 100, and moves with the transmission assembly 100 in the receiving cavity 210, so as to have an initial state of being accommodated in the receiving cavity 210 and an extended state of at least a portion of the speaker module 300 extending out of the receiving cavity 210. The speaker module 300 includes a second magnetic body 310. Among them, one of the first magnetic body 110 and the second magnetic body 310 is wound with a driving coil 400, and the other is driven by the driving coil 400, so that the first magnetic body 110 rotates relative to the second magnetic body 310, and drives the transmission assembly 100 to rotate in the accommodating cavity 210, so that the speaker module 300 can switch between the initial state and the extended state.

[0047] In this way, the transmission assembly 100 is provided with a first magnetic body 110. The speaker module 300 includes a second magnetic body 310, and one of the first magnetic body 110 and the second magnetic body 310 is wound with a driving coil 400. When the driving coil 400 is energized, a magnetic field can be applied to the other, so that the other is driven by the driving coil 400. The transmission assembly 100 is arranged in the accommodating cavity 210 of the housing assembly 200, and is transmission-connected with the housing assembly 200, so that the transmission assembly 100 can move in the accommodating cavity 210. The speaker module 300 is rotationally connected with the transmission assembly 100, so that when the transmission assembly 100 moves in the accommodating cavity 210, the speaker module 300 can also move in the accommodating cavity 210 together. Thereby, the speaker module 300 has an initial state of being accommodated in the accommodating cavity 210 and an extended state of at least partially extending out of the accommodating cavity 210. When the audio experience needs to be improved, the speaker module 300 is in an extended state. At this time, at least part of the speaker module 300 extends out of the accommodating cavity 210, so that the volume of the rear cavity of the speaker module 300 is increased, thereby improving the low-frequency components of the speaker module 300 to achieve a more shocking audio experience without increasing the volume of the speaker rear cavity to occupy the internal space of the electronic device 10. In this way, the audio experience can be improved without increasing the occupied stacking space of the electronic device 10, thereby improving the use experience of the electronic device 10.

[0048] It should be noted that the specific implementation method of one of the first magnetic body 110 and the second magnetic body 310 being wound with the driving coil 400 and the other being driven by the driving coil 400 can be that the first magnetic body 110 is wound with the driving coil 400 and the second magnetic body 310 is driven by the driving coil 400. Alternatively, the second magnetic body 310 is wound with the driving coil 400 and the first magnetic body 110 is driven by the driving coil 400.

[0049] It should be noted that “the transmission assembly 100 can move in the accommodating cavity 210, and the speaker module 300 moves with the transmission assembly 100 in the accommodating cavity 210” should be understood in a broad sense. For example, the transmission assembly 100 rotates in the accommodating cavity 210, and Figure 3 As shown, the speaker module 300 performs telescopic movement along the X direction in the accommodating cavity 210. Alternatively, the transmission assembly 100 performs rotational movement in the accommodating cavity 210, and the speaker module 300 performs rotational movement in the accommodating cavity 210.

[0050] Specifically, Figure 2 as well as Figure 3As shown, the user can also customize the extension ratio (0%-100%) of the speaker module 300 according to different application scenarios. For example, in a scenario where the audio performance requirement is not high, the speaker module 300 is built into the housing of the electronic device 10, that is, it is in the initial state. In scenarios where the audio performance requirement is high, such as voice calls, videos, audio and video entertainment, and games, the speaker module 300 is pushed out by starting the transmission component 100 to increase the volume of the rear cavity and improve the audio performance.

[0051] According to the electromagnetic principle, when other conditions are constant, the greater the magnetic field strength passing through the energized coil, the greater the magnetic field force it generates. In the embodiment of the present disclosure, the magnetic field force is used as the driving force. In order to push the speaker module, the R&D personnel need to increase the magnetic field strength to increase the driving force, thereby making it easier to push the speaker module 300.

[0052] On the basis of the above-mentioned embodiments, in one embodiment, one of the first magnetic body 110 and the second magnetic body 310 is a soft magnetic body and is wound with a driving coil 400, and the other is a hard magnetic body. In this way, the hard magnetic body can generate a strong magnetic field, while the soft magnetic body can guide and concentrate the magnetic field. The driving coil 400 is wound on the soft magnetic body, and the cooperation between the soft magnetic body and the hard magnetic body can increase the magnetic field strength at the location of the driving coil 400. When the driving coil 400 is energized, the magnetic field to which the driving coil 400 is subjected will increase, thereby increasing the driving force, and making it easier to move the speaker module 300 in the accommodating cavity 210. In addition, the soft magnetic body also has the function of demagnetization. When it is not necessary to drive the speaker module 300 to move in the accommodating cavity 210, the soft magnetic body can be demagnetized, thereby reducing the electromagnetic interference to the electrical components in the electronic device 10.

[0053] Of course, in one embodiment, the first magnetic body and the second magnetic body may both be soft magnetic bodies, and a driving coil may be wound around one of them.

[0054] In another embodiment, the first magnetic body and the second magnetic body may both be hard magnets, and a driving coil may be wound around one of them.

[0055] It should be noted that the material of the soft magnetic body may include iron silicon alloy, ferrite, cast steel, cast iron, etc. The material of the hard magnetic body may include tungsten steel, carbon steel, aluminum nickel cobalt alloy, etc.

[0056] Further, in one embodiment, if Figure 4As shown, the first magnetic body 110 is a soft magnetic body and is wound with a driving coil 400. The second magnetic body 310 is a hard magnetic body. In this way, the driving coil 400 is energized and the second magnetic body 310 can generate a magnetic field for the first magnetic body 110, so that the first magnetic body 110 is magnetized, and the magnetic field is guided and concentrated. The magnetic field strength where the driving coil 400 is located is enhanced, thereby increasing the driving force of the driving coil 400 and the second magnetic body 310. It can be understood that such a setting can enable the magnetized first magnetic body 110 to generate a magnetic field force with the second magnetic body 310 in addition to the driving coil 400 being able to generate a driving force for the speaker module 300, so as to generate a driving force for the speaker module 300. Thereby improving the efficiency of switching the speaker module 300 between the initial state and the extended state. In addition, when it is not necessary to drive the speaker module 300 to move in the accommodating cavity 210, the first magnetic body 110 can be demagnetized, thereby avoiding electromagnetic interference to the electrical components in the electronic device 10. In addition, the second magnetic body 310 can provide a magnetic field for the speaker module 300 so that the speaker module 300 can make a sound, and can cooperate with the first magnetic body 110 and the driving coil 400 to enable the speaker module 300 to move in the accommodating cavity 210. Moreover, the second magnetic body 310 applies a magnetic field to the driving coil 400, which can enable the transmission assembly 100 to rotate in the accommodating cavity 210 without adding an additional magnetic body, thereby reducing the occupied space inside the electronic device 10.

[0057] Of course, in another embodiment, the first magnetic body 110 may be a hard magnetic body, and the second magnetic body 310 may be a soft magnetic body and be wound with a driving coil.

[0058] Based on any of the above embodiments, Figure 5 as well as Figure 6 As shown, in one embodiment, the driving coil 400 is wound around the first magnetic body 110. In this way, the driving coil 400 is disposed on the first magnetic body 110 of the transmission assembly 100, and compared with being disposed on the second magnetic body 310, the driving coil 400 is disposed away from the speaker module 300. When the driving coil 400 is energized, the magnetic field generated by it has less influence on the sound of the speaker module 300.

[0059] In one embodiment, the driving coil 400 is fixedly connected to the first magnetic body 110. In this way, the driving coil 400 is fixed on the first magnetic body 110 to improve the reliability of the transmission assembly 100.

[0060] In some embodiments, the driving coil 400 may be fixedly connected to the first magnetic body 110 by bonding.

[0061] In one embodiment, the transmission assembly 100 further includes an adhesive (not shown), and the drive coil 400 is wound around the first magnetic body 110, and then fixedly connected to the first magnetic body 110 through the adhesive. In this way, the drive coil 400 is firstly wound around the first magnetic body 110, so that the drive coil 400 can be initially fixed on the first magnetic body 110. Then, the drive coil 400 is bonded and fixed to the first magnetic body 110 through the adhesive, thereby further fixing the drive coil 400 to the first magnetic body 110. Thus, the reliability of the connection between the transmission assembly 100 and the drive coil 400 is ensured.

[0062] It should be noted that there are many specific implementation methods of the adhesive, including but not limited to glue, hot melt adhesive, etc. In this way, the above-mentioned adhesive has an insulating function, and by fixing the driving coil 400 and the first magnetic body 110, the coils can be insulated or the coil and the first magnetic body 110 can be insulated, thereby ensuring the safety of the electronic device 10.

[0063] It is understandable that there are many specific implementations of "the transmission assembly 100 can move in the accommodating cavity 210, and the speaker module 300 moves with the transmission assembly 100 in the accommodating cavity 210". For example, the transmission assembly 100 rotates in the accommodating cavity 210, and Figure 3 As shown, the speaker module 300 performs telescopic movement along the X direction in the accommodating cavity 210. Alternatively, the transmission assembly 100 performs rotational movement in the accommodating cavity 210, and the speaker module 300 performs rotational movement in the accommodating cavity 210. It is sufficient to realize the switching of the speaker module between the initial state and the extended state.

[0064] Based on any of the above embodiments, Figure 5 as well as Figure 6 As shown, in one embodiment, the transmission assembly 100 further includes a transmission member 120, which is respectively connected to the housing assembly 200 and the first magnetic body 110 in a transmission manner, so that the first magnetic body 110 can move in the accommodating cavity 210, and the speaker module 300 is connected to the first magnetic body 110 in a rotational manner, and moves in the accommodating cavity 210 with the first magnetic body 110. In this way, the first magnetic body 110 is connected to the transmission member 120 in a transmission manner, and the transmission member 120 is connected to the housing assembly 200 in a transmission manner, so that the first magnetic body 110 can move in the accommodating cavity 210. When the speaker module 300 switches between the initial state and the extended state, the driving coil 400 is energized to enable the first magnetic body 110 to rotate relative to the second magnetic body 310, and the speaker module 300 is connected to the first magnetic body 110 in a rotational manner, and moves in the accommodating cavity 210 with the first magnetic body 110. The speaker module 300 moves in the accommodating cavity 210, so that the speaker module 300 can switch between the initial state and the extended state.

[0065] Based on the above embodiments, Figure 5 As shown, in one embodiment, the transmission assembly further includes a matching piece, the first magnetic body is fixedly arranged on the matching piece, and is transmission-connected with the transmission piece through the matching piece, the speaker module 300 is rotationally connected with the matching piece 130, and moves in the accommodating cavity 210 with the matching piece 130. In this way, the matching piece 130 is transmission-connected with the transmission piece 120, and the transmission piece 120 is transmission-connected with the housing assembly 200, so that the matching piece 130 can move in the accommodating cavity 210. When the speaker module 300 switches from the initial state to the extended state, the driving coil 400 is energized to enable the first magnetic body 110 to rotate relative to the second magnetic body 310, and the first magnetic body 110 is arranged on the matching piece 130, that is, the matching piece 130 and the speaker module 300 rotate relative to each other, so that the speaker module 300 moves in the accommodating cavity 210, so that the speaker module 300 can switch between the initial state and the extended state.

[0066] Based on the above embodiments, Figure 6 As shown, in one embodiment, one end of the transmission member 120 is fixedly connected to the matching member 130, and the other end is slidably connected to the housing assembly 200. In this way, when the speaker module 300 switches between the initial state and the extended state, the driving coil 400 is energized to enable the matching member 130 and the speaker module 300 to rotate relative to each other. The matching member 130 is fixedly connected to one end of the transmission member 120 to transmit to the transmission member 120. The other end of the transmission member 120 is slidably connected to the housing assembly 200, so that the matching member 130 can rotate in the accommodating cavity 210. Thereby driving the speaker module 300 to switch between the initial state and the extended state.

[0067] It should be noted that there are many specific implementation methods for fixedly connecting the transmission component 120 and the matching component 130, including but not limited to integral molding, welding, etc.

[0068] Based on the above embodiments, Figure 6 As shown, in one embodiment, the fitting member 130 is slidably connected to the housing assembly 200. Thus, when the fitting member 130 moves in the accommodating cavity 210, the fitting member 130 is slidably connected to the housing assembly 200, which can reduce the friction force on the fitting member 130 in the accommodating cavity 210. In addition, the movement trajectory of the fitting member 130 in the accommodating cavity 210 can be accurately controlled, thereby controlling the movement trajectory of the speaker module 300 in the accommodating cavity 210.

[0069] In another embodiment, Figure 2 as well as Figure 3As shown, the speaker module 300 is slidably connected to the housing assembly 200. In this way, when the speaker module 300 switches between the initial state and the extended state, the speaker module 300 is slidably connected to the housing assembly 200, which can reduce the friction force on the speaker module 300 in the accommodating cavity 210 and control the movement trajectory of the speaker module 300 in the accommodating cavity 210. Thereby, the movement accuracy and positioning accuracy of the speaker module 300 when switching between the initial state and the extended state are improved.

[0070] Of course, the fitting member 130 and the housing assembly 200 may also be slidably connected, and the speaker module 300 may also be slidably connected to the housing assembly 200 .

[0071] Based on the above embodiments, Figure 6 As shown, in one embodiment, the housing assembly 200 is provided with a limiting groove 220, and the transmission member 120 is rotatably connected with a slider 230 adapted to the limiting groove 220, and the transmission member 120 is slidably connected with the housing assembly 200 through the slider 230. In this way, when the speaker module 300 switches between the initial state and the extended state, the driving coil 400 is energized to enable the matching member 130 and the speaker module 300 to rotate relative to each other. The matching member 130 is fixedly connected to one end of the transmission member 120 to transmit with the transmission member 120. The housing assembly 200 is provided with a limiting groove 220, and the other end of the transmission member 120 can only move along the limiting groove 220 through the slider 230, further controlling the movement trajectory of the speaker module 300 in the accommodating cavity 210.

[0072] Specifically, in one embodiment, Figure 6 As shown, the housing assembly 200 includes a middle frame 240, and the limiting groove 220 is provided in the middle frame 240. In this way, the middle frame 240 is provided with the limiting groove 220 so that the transmission assembly 100 can move at the position of the middle frame 240, thereby ensuring that the speaker module 300 switches between the initial state and the extended state at the position of the middle frame 240. The overall aesthetics of the electronic device 10 can be improved.

[0073] Based on the above embodiments, Figures 4 to 6As shown, in one embodiment, the transmission assembly 100 is provided with a through hole 140, and the speaker module 300 is rotatably arranged on the transmission assembly 100 through the through hole 140. The transmission assembly 100 can rotate around the through hole 140 so that the slider 230 can slide along the limiting groove 220. In this way, the speaker module 300 is rotatably arranged on the transmission assembly 100 through the through hole 140, and the movement trajectory of the speaker module 300 in the accommodating cavity 210 can be further controlled. When the speaker module 300 switches between the initial state switching and the extended state, the driving coil 400 is energized to make the transmission assembly 100 and the speaker module 300 rotate relative to each other, the transmission assembly 100 rotates around the through hole 140, and the transmission member 120 can only slide along the limiting groove 220 through the slider 230, so that the speaker module 300 switches between the initial state switching and the extended state.

[0074] On the basis of the above embodiment, in one embodiment, the transmission assembly 100 further includes a gear unit, and the first magnetic body 110 moves in the accommodating cavity 210 through the gear unit. In this way, when the speaker module 300 switches between the initial state and the extended state, the gear unit can drive the first magnetic body 110 to move in the accommodating cavity 210, and the first magnetic body 110 rotates relative to the second magnetic body 310, and drives the transmission assembly 100 to rotate in the accommodating cavity 210, so that the speaker module 300 can switch between the initial state and the extended state. The use of gear transmission can improve the control accuracy of the extension ratio of the speaker module 300.

[0075] Specifically, in one embodiment, Figure 7 As shown, the housing assembly 200 includes a rack 250 fixed to the side wall of the accommodating cavity 210, and the gear unit includes a first gear 150, the first gear 150 is rotatably connected to the speaker module 300, and is fixedly connected to the first magnetic body 110, and the first gear 150 is meshed with the rack 250. In this way, when the speaker module 300 switches between the initial state and the extended state, the drive coil 400 is energized, and the drive coil 400 cooperates with the second magnetic body 310, which can drive the first gear 150 to rotate, and the first gear 150 and the rack 250 are driven and matched, so that the first gear 150 is extended and retracted along the length direction of the rack 250, so that the speaker module 300 performs a telescopic movement in the accommodating cavity 210 along the arrow direction to switch between the initial state and the extended state. In addition, by using the transmission and matching of the gear rack, the movement of the speaker module 300 can be converted into a linear motion, so as to reduce the space occupied by the speaker module 300 during the movement process, thereby reducing the space occupied by the speaker module 300 inside the electronic device 10.

[0076] In another embodiment, if Figure 8As shown, the housing assembly 200 includes a fixed gear 260 fixed to the side wall of the accommodating cavity 210, and the gear unit includes a second gear 160, the second gear 160 is rotatably connected to the speaker module 300, and is fixedly connected to the first magnetic body 110, and the second gear 160 is meshed with the fixed gear 260. In this way, when the speaker module 300 switches between the initial state and the extended state, the driving coil 400 is energized, so that the second gear 160 and the fixed gear 260 are matched with each other, so that the transmission assembly 100 rotates in the accommodating cavity 210, and the speaker module 300 is rotatably connected to the transmission assembly 100, so that the speaker module 300 rotates in the accommodating cavity 210 along the direction of the arrow to switch between the initial state and the extended state.

[0077] It should be noted that the gear meshing mentioned above can be direct meshing or indirect meshing. When indirect meshing, it can be achieved by transmission through another gear. That is, the first gear 150, the second gear 160, the fixed gear 260, etc. can include one or more gears.

[0078] Based on any of the above embodiments, Figures 2 to 3 As shown, in one embodiment, the speaker module 300 is plugged into the accommodating cavity 210, and the electronic device 10 includes a sealing ring 500, which is sandwiched in the gap between the speaker module 300 and the accommodating cavity 210. In this way, the provision of the sealing ring 500 can make the interior of the electronic device 10 waterproof and dustproof after the speaker module 300 is plugged into the accommodating cavity 210, thereby improving the reliability of the electronic device 10.

[0079] It should be noted that there are many specific implementation methods for the sealing ring 500 to be sandwiched in the gap between the speaker module 300 and the accommodating chamber 210. For example, the speaker module 300 is provided with a first groove 360 ​​adapted to the sealing ring 500, and the sealing ring 500 is sleeved on the speaker module 300 through the first groove 360, and the speaker module 300 is then plugged and matched with the accommodating chamber 210. Alternatively, the inner side wall of the accommodating chamber 210 is provided with a second groove 370 adapted to the sealing ring 500, and the sealing ring 500 is installed in the accommodating chamber 210 through the second groove 370, and the speaker module 300 is then plugged and matched with the accommodating chamber 210. In this way, the first groove 360 ​​and the second groove 370 can make the sealing ring 500 more firmly sandwiched in the gap between the speaker module 300 and the accommodating chamber 210, so as to avoid the sealing ring 500 from being disconnected from the speaker module 300 and the accommodating chamber 210 when the speaker module 300 switches between the initial state and the extended state. Thereby, the reliability of the electronic device 10 is improved.

[0080] Based on any of the above embodiments, Figure 4As shown, in one embodiment, the speaker module 300 includes a diaphragm 320 and a voice coil 330. The voice coil 330 can generate electromagnetic induction with the second magnetic body 310 so that the voice coil 330 can move, and the diaphragm 320 is connected to the voice coil 330. In this way, when the speaker module 300 needs to make a sound, the voice coil 330 is energized to generate electromagnetic induction with the second magnetic body 310, so that the voice coil 330 will move. The diaphragm 320 is connected to the voice coil 330, so that the voice coil 330 drives the diaphragm 320 to vibrate, thereby making the speaker module 300 make a sound.

[0081] Based on the above embodiments, Figure 4 As shown, in one embodiment, the speaker module 300 further includes a magnetic base 340 and a core 350 disposed on the magnetic base 340, the second magnetic body 310 is annular and is disposed on the magnetic base 340, the second magnetic body 310 is sleeved on the outer side of the core 350, and the second magnetic body 310 and the outer side of the core 350 are spaced to form a first gap 380. The voice coil 330 is movably disposed in the first gap 380. In this way, the second magnetic body 310 is disposed on the magnetic base 340 and is annularly sleeved on the outer side of the core 350. The second magnetic body 310 can generate a magnetic field with the magnetic base 340. The voice coil 330 is disposed in the first gap 380 formed by the second magnetic body 310 and the outer side of the core 350. The voice coil 330 moves in the first gap 380 under the action of the magnetic field. The voice coil 330 is connected to the diaphragm 320, so that the diaphragm 320 vibrates, so that the speaker module 300 can make a sound. In addition, the magnetic base 340 can guide the direction of the magnetic field, thereby enhancing the magnetic field where the energized voice coil 330 is located, thereby improving the sound quality of the speaker module 300 .

[0082] On the basis of the above embodiments, in one embodiment, the core 350 is a magnet or a magnetic conductor. Thus, when the core 350 is a magnet, the core 350 can generate a magnetic field loop with the second magnetic body 310, and the voice coil 330 is arranged between the core 350 and the first gap 380 of the second magnetic body 310. The magnetic field where the voice coil 330 is located is enhanced, thereby improving the sound quality of the speaker module 300. When the core 350 is a magnetic conductor, the second magnetic body 310 can also generate a magnetic field loop with the core 350, and the magnetic conductor has no residual magnetism after the magnetic field disappears, thereby avoiding the influence of the magnetic field generated by it on the electrical components, thereby improving the reliability of the electronic device 10.
