Description
Technical Field
[0001] The present application belongs to the field of acoustic equipment, and specifically relates to an acoustic module and electronic equipment. Background Art
[0002] Electronic devices are equipped with acoustic modules, which convert the electrical signals of the electronic devices into sound signals to make sounds. As the application scope of electronic devices becomes wider and wider, people's demand for the performance of electronic devices is also getting higher and higher. For example, the music, video, games, and calls of electronic devices all require the acoustic modules to have good sound performance to enhance the user experience. Therefore, the sound performance requirements of the acoustic modules are also increasing.
[0003] In an acoustic module, such as a speaker, receiver, or other acoustic module, a magnetic field is formed by a magnet, and a voice coil is located in the magnetic field. When an alternating current is passed through the voice coil, the voice coil reciprocates in the magnetic field, thereby driving the diaphragm to move, and then pushing the air to make a sound. The magnetic field formed by the magnet is stronger in the area close to the magnet and weaker in the area far from the magnet. During the reciprocating motion of the voice coil, when the voice coil moves to a position far from the magnet, the magnetic field is weak, resulting in insufficient magnetic force, thereby affecting the sound performance of the acoustic module. Summary of the invention
[0004] The purpose of the embodiments of the present application is to provide an acoustic module and an electronic device that can solve the problem of insufficient magnetic force and thus affecting the sound performance when the voice coil is away from the magnet during the reciprocating motion of the voice coil.

The side magnet is arranged on the outside of the central magnet. There is a first gap between the side magnet and the central magnet. The voice coil is opposite to the first gap and can reciprocate in and out of the first gap. The magnetic bowl, the central magnet and the side magnet cooperate to form a magnetic field. The voice coil is located in the magnetic field. When an alternating current is passed through the voice coil, the voice coil can reciprocate in the magnetic field, thereby driving the diaphragm connected to the voice coil to move, and then promoting the air to make sound. The magnetic conductive component is arranged on the voice coil. The magnetic conductive component includes a first magnetic conductive part and a second magnetic conductive part.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0029] The acoustic module provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.
[0030] like Figures 1 to 7 As shown, an embodiment of the present application provides an acoustic module, through which the electrical signal of an electronic device is converted into a sound signal to emit sound. The acoustic module includes a shell 920, a magnetic bowl 100, a center magnet 200, a side magnet 300, a voice coil 400, a diaphragm 700 and a magnetic conductive component.
[0031] Among them, the shell 920 is the main component of the acoustic module, and can provide an installation foundation and installation space for other structural parts of the acoustic module. The shell 920 can be a shell 920 of a steel sheet structure or a plastic structure. The shell 920 has a accommodating cavity, and other structural parts of the acoustic module are arranged in the accommodating cavity. For example, the magnetic bowl 100, the center magnet 200, the side magnet 300, the voice coil 400, and the diaphragm 700 are all arranged in the accommodating cavity of the shell 920.
[0032] The magnetic bowl 100 is disposed in the housing 920, and the central magnet 200 and the side magnet 300 are both disposed in the magnetic bowl 100. The magnetic bowl 100 can provide support for the central magnet 200 and the side magnet 300, and the magnetic bowl 100 can also promote the formation of a magnetic field between the central magnet 200 and the side magnet 300. The side magnet 300 is disposed outside the central magnet 200, and there is a first gap 600 between the side magnet 300 and the central magnet 200. The magnetic bowl 100, the central magnet 200, and the side magnet 300 cooperate to form a magnetic field in and near the first gap 600.
[0033] The diaphragm 700 is disposed in the housing 920, and the diaphragm 700 is connected to the housing 920. The diaphragm 700 and the housing 920 may be elastically connected, and when the diaphragm 700 vibrates in the accommodating cavity of the housing 920, the connection between the diaphragm 700 and the housing 920 will not be damaged. For example, the diaphragm 700 may be connected to the housing 920 via an elastic folding ring 710. Alternatively, the diaphragm 700 may be connected to the bracket 910 via an elastic folding ring 710, and the bracket 910 is connected to the housing 920, or the bracket 910 is a part of the housing 920.
[0034] The voice coil 400 is arranged on the diaphragm 700. The voice coil 400 is opposite to the first gap 600 and can reciprocate in and out of the first gap 600. The central magnet 200 and the side magnet 300 cooperate to form a magnetic field in the first gap 600 and near the first gap 600. The voice coil 400 is located in the magnetic field. When an alternating current is passed through the voice coil 400, the voice coil 400 can reciprocate in the magnetic field, thereby reciprocating in and out of the first gap 600, and can drive the diaphragm 700 connected to the voice coil 400 to move, thereby promoting the air between the diaphragm 700 and the shell 920 to vibrate, so as to produce sound, and transmit it to the outside of the shell 920 through the sound outlet 930.
[0035] The magnetic conductive component is disposed on the voice coil 400, and includes a first magnetic conductive part 530 and a second magnetic conductive part 540. The first magnetic conductive part 530 is at least partially located on a side of the voice coil 400 close to the center magnet 200, and the second magnetic conductive part 540 is at least partially located on a side of the voice coil 400 close to the side magnet 300. The first magnetic conductive part 530 and the second magnetic conductive part 540 of the magnetic conductive component can guide the magnetic field to gather near the voice coil 400, increase the magnetic field strength in the area where the voice coil 400 is located, and thus increase the magnetic force. Therefore, even if the voice coil 400 moves to an area with a weak magnetic field, under the action of the magnetic conductive component, the magnetic field around the voice coil 400 can be gathered near the voice coil 400, thereby increasing the magnetic force, thereby increasing the volume, improving the sound quality, and improving the sound performance of the acoustic module.
[0036] In the embodiment of the present application, the voice coil 400 has a first end and a second end, the first end is opposite to the magnetic bowl 100, and the second end is away from the magnetic bowl 100, and the first magnetic conductive member 530 and the second magnetic conductive member 540 are both arranged at the first end. The first end is the end of the voice coil 400 closest to the magnetic bowl 100. When the voice coil 400 moves away from the magnetic bowl 100, the first end of the voice coil 400 also gradually moves away from the magnetic bowl 100, thereby gradually moving away from the magnetic field formed by the center magnet 200 and the side magnet 300. When the first end moves to an area with a weaker magnetic field, the magnetic field strength passing through the voice coil 400 is weak, and the magnetic force on the voice coil 400 is small at this time. The first magnetic conductive member 530 and the second magnetic conductive member 540 are both arranged at the first end, which can guide the magnetic field to gather near the first end of the voice coil 400, thereby increasing the magnetic field strength in the area where the first end of the voice coil 400 is located, thereby increasing the magnetic force. Therefore, even if the voice coil 400 moves to an area with a weaker magnetic field, the magnetic field around the voice coil 400 can be gathered near the voice coil 400 under the action of the magnetic conductive component, thereby enhancing the magnetic force, thereby increasing the volume, improving the sound quality, and improving the sound performance of the acoustic module.
[0037] Specifically, the first magnetic conductive component 530 may include a first side magnetic conductive portion 531 and a first end magnetic conductive portion 532 connected to each other, and the second magnetic conductive component 540 may include a second side magnetic conductive portion 541 and a second end magnetic conductive portion 542 connected to each other, the first side magnetic conductive portion 531 is located on the side of the voice coil 400 close to the center magnet 200, the second side magnetic conductive portion 541 is located on the side of the voice coil 400 close to the side magnet 300, the first end magnetic conductive portion 532 and the second end magnetic conductive portion 542 are both located between the side of the first end facing the magnetic bowl 100 and the magnetic bowl 100, and a second gap 550 is provided between the first end magnetic conductive portion 532 and the second end magnetic conductive portion 542.
[0038] The first side magnetic conductive part 531 and the second side magnetic conductive part 541 cooperate to guide the magnetic field to gather near the voice coil 400 and pass through the voice coil 400, thereby increasing the magnetic field strength in the area where the voice coil 400 is located, thereby increasing the magnetic force. The first end magnetic conductive part 532 and the second end magnetic conductive part 542 can increase the contact area between the first magnetic conductive part 530 and the second magnetic conductive part 540 and the voice coil 400, so that the first magnetic conductive part 530 and the second magnetic conductive part 540 are more firmly connected to the voice coil 400, and it is also convenient to install the first magnetic conductive part 530 and the second magnetic conductive part 540 to the voice coil 400. At the same time, the first end magnetic conductive portion 532 and the second end magnetic conductive portion 542 are connected to the voice coil 400 at the ends of the voice coil 400, so as to prevent the first side magnetic conductive portion 531 and the second side magnetic conductive portion 541 from moving relative to the voice coil 400 along the movement direction of the voice coil 400 during the reciprocating motion of the voice coil 400, that is, to prevent the first side magnetic conductive portion 531 and the second side magnetic conductive portion 541 from sliding relative to the voice coil 400 due to inertia.
[0039] In addition, there is a second gap 550 between the first end magnetic conductive portion 532 and the second end magnetic conductive portion 542, which can avoid the first end magnetic conductive portion 532 and the second end magnetic conductive portion 542 from being connected. The magnetic field cannot directly pass through the first end magnetic conductive portion 532 and the second end magnetic conductive portion 542, but needs to pass through the voice coil 400, thereby concentrating the magnetic field near the voice coil 400 and improving the magnetic field strength in the area where the voice coil 400 is located.
[0040] In the embodiment of the present application, the magnetic conductive component also includes a third magnetic conductive component 510 and a fourth magnetic conductive component 520, the third magnetic conductive component 510 is at least partially located on the side of the voice coil 400 close to the center magnet 200, the fourth magnetic conductive component 520 is at least partially located on the side of the voice coil 400 close to the side magnet 300, and the third magnetic conductive component 510 and the fourth magnetic conductive component 520 are both arranged at the second end.
[0041] The second end is the end of the voice coil 400 farthest from the magnetic bowl 100. When the voice coil 400 moves away from the magnetic bowl 100, the second end of the voice coil 400 also gradually moves away from the magnetic bowl 100, thereby gradually moving away from the magnetic field formed by the center magnet 200 and the side magnet 300, and the second end first moves to the area with a weaker magnetic field. The third magnetic conductive component 510 and the fourth magnetic conductive component 520 are both arranged at the second end, which can guide the magnetic field to gather near the second end of the voice coil 400, increase the magnetic field strength in the area where the second end of the voice coil 400 is located, and thus increase the magnetic force. Therefore, even if the voice coil 400 moves to an area with a weaker magnetic field, under the action of the magnetic conductive component, the magnetic field around the voice coil 400 can be gathered near the voice coil 400, thereby increasing the magnetic force, thereby increasing the volume, improving the sound quality, and improving the sound performance of the acoustic module.
[0042] In the embodiment of the present application, a first magnetic conductive component 530 and a second magnetic conductive component 540 can be set at the first end, and a third magnetic conductive component 510 and a fourth magnetic conductive component 520 can be set at the second end. Magnetic conductive components are set at both ends of the voice coil 400. The magnetic field around the voice coil 400 can be gathered as much as possible near the voice coil 400, thereby enhancing the magnetic force, thereby increasing the volume, improving the sound quality, and improving the sound performance of the acoustic module.
[0043] Specifically, the third magnetic conductive component 510 includes a third side magnetic conductive portion 511 and a third end magnetic conductive portion 512 connected to each other, and the fourth magnetic conductive component 520 includes a fourth side magnetic conductive portion 521 and a fourth end magnetic conductive portion 522 connected to each other, the third side magnetic conductive portion 511 is located on a side of the voice coil 400 close to the center magnet 200, the fourth side magnetic conductive portion 521 is located on a side of the voice coil 400 close to the side magnet 300, the third end magnetic conductive portion 512 and the fourth end magnetic conductive portion 522 are both located on the side of the second end away from the magnetic bowl 100, and a third gap 560 is provided between the third end magnetic conductive portion 512 and the fourth end magnetic conductive portion 522.
[0044] The third side magnetic conductive part 511 and the fourth side magnetic conductive part 521 cooperate to guide the magnetic field to gather near the voice coil 400 and pass through the voice coil 400, thereby increasing the magnetic field strength in the area where the voice coil 400 is located, thereby increasing the magnetic force. The third end magnetic conductive part 512 and the fourth end magnetic conductive part 522 can increase the contact area between the third magnetic conductive part 510 and the fourth magnetic conductive part 520 and the voice coil 400, so that the third magnetic conductive part 510 and the fourth magnetic conductive part 520 are more firmly connected to the voice coil 400, and it is also convenient to install the third magnetic conductive part 510 and the fourth magnetic conductive part 520 to the voice coil 400. At the same time, the third end magnetic conductive portion 512 and the fourth end magnetic conductive portion 522 are connected to the voice coil 400 at the ends of the voice coil 400, so as to prevent the third side magnetic conductive portion 511 and the fourth side magnetic conductive portion 521 from moving relative to the voice coil 400 along the movement direction of the voice coil 400 during the reciprocating motion of the voice coil 400, that is, to prevent the third side magnetic conductive portion 511 and the fourth side magnetic conductive portion 521 from sliding relative to the voice coil 400 due to inertia.
[0045] In addition, there is a third gap 560 between the third end magnetic conductive portion 512 and the fourth end magnetic conductive portion 522, which can avoid the third end magnetic conductive portion 512 and the fourth end magnetic conductive portion 522 from being connected. The magnetic field cannot directly pass through the third end magnetic conductive portion 512 and the fourth end magnetic conductive portion 522, but needs to pass through the voice coil 400, thereby concentrating the magnetic field near the voice coil 400 and improving the magnetic field strength in the area where the voice coil 400 is located.
[0046] The voice coil 400 can be directly connected to the diaphragm 700. The voice coil 400 moves in the magnetic field, driving the diaphragm 700 to vibrate. In the embodiment of the present application, the voice coil 400 is connected to the diaphragm 700 through the third magnetic conductive member 510 and the fourth magnetic conductive member 520. Therefore, the third magnetic conductive member 510 and the fourth magnetic conductive member 520 can not only gather the magnetic field near the voice coil 400 and improve the magnetic field strength in the area where the voice coil 400 is located, but also connect the voice coil 400 and the diaphragm 700. In addition, the third magnetic conductive member 510 and the fourth magnetic conductive member 520 are connected to the voice coil 400 on one side and to the diaphragm 700 on the other side, which further improves the connection reliability of the third magnetic conductive member 510 and the fourth magnetic conductive member 520 on the voice coil 400.
[0047] In the embodiment of the present application, the first magnetic conductive member 530 and the second magnetic conductive member 540 are both annular components, and the first magnetic conductive member 530 and the second magnetic conductive member 540 are both arranged around the voice coil 400. The entire annular periphery of the voice coil 400 has magnetic conductive components to gather the magnetic field near the voice coil 400, thereby increasing the magnetic field strength in the area where the voice coil 400 is located. At the same time, the first magnetic conductive member 530 and the second magnetic conductive member 540 are directly sleeved outside or inside the voice coil 400, which facilitates the installation of the first magnetic conductive member 530 and the second magnetic conductive member 540.
[0048] Optionally, the first magnetic conductive member 530 and the second magnetic conductive member 540 may be bonded to the voice coil 400 by glue or the like.
[0049] The third magnetic conductive member 510 and the fourth magnetic conductive member 520 are both annular components, and are disposed around the voice coil 400. The entire annular periphery of the voice coil 400 has magnetic conductive components to gather the magnetic field near the voice coil 400, thereby increasing the magnetic field strength in the area where the voice coil 400 is located. At the same time, the third magnetic conductive member 510 and the fourth magnetic conductive member 520 are directly sleeved outside or inside the voice coil 400, which facilitates the installation of the third magnetic conductive member 510 and the fourth magnetic conductive member 520.
[0050] Optionally, the third magnetic conductive member 510 and the fourth magnetic conductive member 520 may be bonded to the voice coil 400 by glue or the like.
[0051] In the embodiment of the present application, the acoustic module further includes a magnetic conductive sheet 800, which is disposed on the central magnet 200 and the side magnet 300, and the magnetic conductive sheet 800 is located on the side of the central magnet 200 and the side magnet 300 away from the magnetic bowl 100. The magnetic conductive sheet 800 has good magnetic conductivity and can guide the magnetic field formed between the central magnet and the side magnet 300 to pass through the voice coil 400 to a large extent. In addition, the magnetic conductive sheet 800, the central magnet 200, the side magnet 300 and the magnetic bowl 100 can promote the formation of a closed magnetic field.
[0052] The acoustic module in the embodiment of the present application may be a speaker, a receiver, etc., and of course may also be other acoustic modules.
[0053] The embodiment of the present application also provides an electronic device, which includes the above-mentioned acoustic module. The acoustic module is characterized in that it includes a shell 920, a magnetic bowl 100, a central magnet 200, a side magnet 300, a voice coil 400, a diaphragm 700 and a magnetic conductive component; the magnetic bowl 100 is arranged in the shell 920, the central magnet 200 and the side magnet 300 are both arranged in the magnetic bowl 100, and the side magnet 300 is arranged on the outside of the central magnet 200, and there is a first gap 600 between the side magnet 300 and the central magnet 200, and the diaphragm 700 is arranged in the shell 920, The diaphragm 700 is connected to the shell 920, and the voice coil 400 is arranged on the diaphragm 700. The voice coil 400 is opposite to the first gap 600 and can reciprocate in and out of the first gap 600; the magnetic conductive component is arranged on the voice coil 400, and the magnetic conductive component includes a first magnetic conductive part 530 and a second magnetic conductive part 540.

[0054] The magnetic bowl 100, the center magnet 200 and the side magnet 300 cooperate to form a magnetic field. The voice coil 400 is located in the magnetic field. When an alternating current is passed through the voice coil 400, the voice coil 400 can reciprocate in the magnetic field, thereby driving the diaphragm 700 connected to the voice coil 400 to move, thereby pushing the air to make sounds. The magnetic conductive component is arranged on the voice coil 400. The first magnetic conductive part 530 and the second magnetic conductive part 540 of the magnetic conductive component can guide the magnetic field to gather near the voice coil 400, increase the magnetic field strength in the area where the voice coil 400 is located, and thus increase the magnetic force. Therefore, even if the voice coil 400 moves to an area with a weaker magnetic field, under the action of the magnetic conductive component, the magnetic field around the voice coil 400 can be gathered near the voice coil 400, thereby increasing the magnetic force, thereby increasing the volume, improving the sound quality, and improving the sound performance of the acoustic module.
