DETAILED DESCRIPTION
[0010] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

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.
[0012] like Figure 1-Figure 6 As shown, the embodiment of the present application discloses a speaker which has both sound generation and vibration functions. Figure 2As shown, the speaker includes a frame 110, a base 120, a diaphragm 210, a voice coil 220, a first magnet 310, a second magnet 320, a first electromagnet 410, a second electromagnet 420, a first vibration module 510 and a second vibration module 520. Of course, the speaker can also generally include a circuit board 140 and other devices so that the speaker can directly or indirectly form an electrical connection relationship with the battery in the electronic device to ensure that the speaker can make a sound and vibrate when powered on. Of course, the speaker can also perform sound work alone, and accordingly, the speaker can also perform vibration work alone. As mentioned above, in the speaker disclosed in the embodiment of the present application, the first vibration module 510 and the second vibration module 520 are included. For this reason, in the embodiment of the present application, the first vibration module 510 and the second vibration module 520 in the speaker can also be independently wired to have the ability to vibrate alone.
[0013] The frame 110 and the base 120 are both external structures of the speaker, and the two are fixedly connected and can serve as the outer shell of the speaker, so that other devices in the speaker can be directly or indirectly installed in the structure formed by the frame 110 and the base 120. To this end, in the embodiment of the present application, the diaphragm 210, the first magnet 310, the second magnet 320, the first vibration module 510 and the second vibration module 520 are all installed in the frame 110. The first magnet 310 and the second magnet 320 can both be permanent magnets to reduce the cost of the entire speaker and the control difficulty of the speaker. The first electromagnet 410 and the second electromagnet 420 both include coils. In detail, the edge of the diaphragm 210 is fixedly connected to the frame 110, the first magnet 310 and the second magnet 320 are relatively fixed to the frame 110, and the first vibration module 510 and the second vibration module 520 are assembled to the frame 110 in a movable connection, so as to ensure that the first vibration module 510 and the second vibration module 520 can reciprocate in the thickness direction of the diaphragm 210 and the first direction relative to the frame 110 under the drive of the corresponding device to produce a vibration effect. It should be noted that the first direction is a direction perpendicular to the thickness direction of the diaphragm 210.
[0014] More specifically, the frame 110 and the base 120 can be formed of hard materials such as plastic or metal, and the specific shapes of the two can be flexibly selected according to actual needs, which is not limited in this article. Usually, the speaker is generally a cubic structure. For this reason, in the embodiment of the present application, the frame 110 can be generally a rectangular closed ring structure, and the base 120 can be generally a rectangular plate structure. The circuit board 140 can be installed on the base 120, so that the device installed on the inner side of the frame 110 can form an electrical connection relationship with the circuit board 140, and then be connected to the battery or mainboard and other devices outside the speaker through the circuit board 140.
[0015] In more detail, the base 120 can be mounted on one end of the frame 110 by means of a screw or other connector, or by means of bonding or clamping or other connectors, and the diaphragm 210 can be mounted on the other end of the frame 110 by means of bonding or other connectors, so as to ensure that the diaphragm 210 can vibrate to emit a sound signal. Of course, in order to ensure that the diaphragm 210 can vibrate, the diaphragm 210 needs to form a corresponding matching relationship with the voice coil 220 and the first magnet 310.
[0016] To this end, in the embodiment of the present application, the diaphragm 210 and the voice coil 220 can be fixedly connected by bonding or other means, and then when the voice coil 220 moves relative to the frame 110, the voice coil 220 can drive the diaphragm 210 to move relative to the frame 110. Specifically, the voice coil 220 is a coil that can be energized, that is, the voice coil 220 is essentially an electromagnet, and then, in the embodiment of the present application, by making the voice coil 220 cooperate with the first magnet 310, and when the current with alternating directions is passed through the voice coil 220, the voice coil 220 can drive the diaphragm 210 to vibrate along the thickness direction of the diaphragm 210 itself, and the frequency and amplitude of the vibration are related to the parameters of the current passed through the voice coil 220, which is not limited herein.
[0017] More specifically, the first magnet 310 can be fixedly installed in the frame 110, for example, the outer surface of the first magnet 310 can be fixedly connected to the inner surface of the frame 110 by bonding; in another embodiment of the present application, a mounting seat 130 can also be provided, the mounting seat 130 is fixedly connected to the frame 110, and the first magnet 310 can be installed on the mounting seat 130. Further, the voice coil 220 and the first electromagnet 410 can be respectively located on opposite sides of the mounting seat 130, so as to make the isolation between the components of the speaker that realize multiple functions better as much as possible. In this case, the mounting seat 130 can be provided with a through hole, and the first magnet 310 can be embedded in the through hole, so that a part of the first magnet 310 can be located on the side of the mounting seat 130 facing the diaphragm 210, and the other part of the first magnet 310 can be located on the side of the mounting seat 130 away from the diaphragm 210, so as to ensure that the magnetic matching effect between the voice coil 220 and the first electromagnet 410 and the first magnet 310 is relatively good.
[0018] In addition, in order to improve the sound effect of the diaphragm 210, in the embodiment of the present application, the first magnet 310 can be a component structure, that is, the first magnet 310 includes a plurality of independent magnets, and the magnetic fields between the plurality of magnets cooperate with each other to ensure that the effect of the total magnetic field formed is relatively better.
[0019] The voice coil 220 and the first magnet 310 are distributed along the thickness direction of the diaphragm 210 as a whole, or in other words, the magnetic poles of the voice coil 220 and the first magnet 310 are distributed in the same direction, so that when an alternating current is passed through the voice coil 220, the first magnet 310 can drive the voice coil 220 to move alternately in a direction away from the base 120 and a direction close to the base 120, thereby allowing the diaphragm 210 to vibrate along its own thickness direction.
[0020] In the embodiment of the present application, in order to enable the speaker to vibrate in the thickness direction of the diaphragm 210, the first electromagnet 410 is connected to the first vibration module 510, and the first electromagnet 410 also cooperates with the first magnet 310, so that when the current with alternating directions is passed into the first electromagnet 410, the first electromagnet 410 can drive the first vibration module to vibrate in the thickness direction of the diaphragm 210. Accordingly, in the process of arranging the first vibration module and the first electromagnet 410, it is necessary to make the magnetic pole distribution direction of the first electromagnet 410 the same as the magnetic pole distribution direction of the first magnet 310, so as to ensure that when the current with alternating directions is passed into the first electromagnet 410, the first vibration module can be driven to change back and forth between the direction approaching the base 120 and the direction away from the base 120 under the action of the first magnet 310. More specifically, the magnetic pole distribution direction of the first electromagnet 410 and the magnetic pole distribution direction of the first magnet 310 are both the thickness direction of the diaphragm 210 . Accordingly, the magnetic pole distribution direction of the voice coil 220 is also the thickness direction of the diaphragm 210 .
[0021] At the same time, in the embodiment of the present application, in order to enable the speaker to also have the ability to vibrate in the first direction, the second electromagnet 420 is connected to the second vibration module 520, and the second electromagnet 420 is also coordinated with the second magnet 320, so that when the current with alternating directions is passed into the second electromagnet 420, the second electromagnet 420 can drive the second vibration module to vibrate in the thickness direction of the diaphragm 210. Accordingly, in the process of arranging the second vibration module and the second electromagnet 420, it is necessary to make the magnetic pole distribution direction of the second electromagnet 420 the same as the magnetic pole distribution direction of the second magnet 320, so as to ensure that when the current with alternating directions is passed into the second electromagnet 420, the second vibration module can be driven to change back and forth between the direction approaching the base 120 and the direction away from the base 120 under the action of the second magnet 320. More specifically, the magnetic pole distribution direction of the second electromagnet 420 and the magnetic pole distribution direction of the second magnet 320 are both the first direction.
[0022] The speaker disclosed in the embodiment of the present application has a base 120 fixedly connected to the frame 110, and the diaphragm 210, the first magnet 310, the second magnet 320, the first vibration module 510 and the second vibration module 520 are all installed on the frame 110. By fixing the diaphragm 210 and the voice coil 220, and making the voice coil 220 cooperate with the first magnet 310, the voice coil 220 can drive the diaphragm 210 to vibrate along the thickness direction of the diaphragm 210, thereby achieving the purpose of sound generation.
[0023] Furthermore, in the speaker disclosed in the embodiment of the present application, the first electromagnet 410 is connected to the first vibration module 510, and the first electromagnet 410 cooperates with the first magnet 310, so that the first electromagnet 410 can drive the first vibration module 510 to vibrate in the thickness direction of the diaphragm 210; at the same time, the second electromagnet 420 is connected to the second vibration module 520, and the second electromagnet 420 cooperates with the second magnet 320, so that the second electromagnet 420 can drive the second vibration module 520 to vibrate in the first direction, and the first direction is perpendicular to the thickness direction of the diaphragm 210, so that the speaker has the ability to provide vibration in two directions, and the vibration processes in the two directions are independent of each other, and the vibration experience is relatively good.
[0024] As described above, in the loudspeaker disclosed in the embodiment of the present application, on the one hand, the first electromagnet 410 and the voice coil 220 share the first magnet 310, thereby achieving the purpose of reusing the original magnetic circuit space in the loudspeaker. At the same time, the device with sound-generating ability in the loudspeaker, and the device that provides vibration functions in two different directions respectively share the same base 120 and frame 110 of the outer shell structure, so that the overall space occupied by the loudspeaker with both sound-generating ability and multi-directional vibration ability can be relatively small.
[0025] In addition, the loudspeaker disclosed in the embodiment of the present application can be applied to electronic devices such as mobile phones. In this case, the correspondence between the thickness direction of the diaphragm and the first direction and the three-dimensional direction of the electronic device can be flexibly determined according to actual needs. In a specific embodiment of the present application, the thickness direction of the diaphragm can be made to correspond to the thickness direction of the electronic device, that is, the two are parallel to each other, and the first direction is made parallel to the width direction of the electronic device, which enables the electronic device to have the ability to vibrate in the conventional X and Z directions, and as mentioned above, the vibration processes between the two directions are independent of each other, thereby improving the vibration effect of the electronic device.
[0026] In a specific embodiment of the present application, the first vibration module 510 may include a first vibrator 511, the second vibration module 520 may include a second vibrator 521, and the second vibrator 521 may be arranged between the first magnet 310 and the base 120, so that the coverage area of the second vibrator 521 in a plane perpendicular to the thickness direction of the vibration membrane 210 can be relatively large, thereby making the vibration effect of the second vibration module 520 relatively good.
[0027] In order to further save installation space, more specifically, the second vibrator 521 is provided with a mounting hole 5211, and the mounting hole 5211 penetrates the second vibrator 521 along the thickness direction of the diaphragm 210. By installing at least a portion of the first vibrator 511 in the mounting hole 5211, the first vibrator 511 and the second vibrator 521 can share part of the space in the frame 110, thereby achieving the purpose of further saving installation space. Of course, in order to ensure that the vibration performance of the first vibrator 511 is still relatively good, in the embodiment of the present application, the first electromagnet 410 is located on the side of the second vibrator 521 away from the base 120, and the first vibrator 511 is fixedly connected to the first electromagnet 410, so that the first electromagnet 410 and the first magnet 310 are both located on the same side of the second vibrator 521, ensuring that the magnetic matching effect between the first electromagnet 410 and the first magnet 310 is still relatively good, thereby ensuring that the vibration effect of the second vibrator 521 is also relatively good.
[0028] Specifically, when the frame 110 is a rectangular closed ring structure, the second vibrator 521 as a whole can be a cubic structure, and the shape of its mounting hole 5211 can be a rectangular hole. In another embodiment of the present application, in order to reduce the difficulty of assembling the first vibrator 511 and the second vibrator 521, and reduce the difficulty of processing the mounting hole 5211, the mounting hole 5211 can be a cylindrical hole. Correspondingly, the first vibrator 511 can be a cylindrical structure, or in other words, the partial structure of the first vibrator 511 installed in the mounting hole 5211 can be a cylindrical structure.
[0029] In addition, in order to ensure that the vibration processes of the first vibrator 511 and the second vibrator 521 do not interfere with each other, in the embodiment of the present application, in the first direction, it is necessary to make the sum of the double value of the amplitude A of the second vibrator 521 and the size d of the first vibrator 511 in the first direction smaller than the size D of the mounting hole 5211, that is, 2A+d<D, wherein the amplitude A of the second vibrator 521 is the maximum distance that the second vibrator 521 moves along the first direction from the initial position. In this case, by centrally installing the first vibrator 511 in the mounting hole 5211, it can be ensured that the second vibrator 521 will not collide or contact with the first vibrator 511 during the vibration process, thereby ensuring the independence of the vibration of the first vibrator 511 and the second vibrator 521 on the one hand, and preventing the first vibrator 511 and the second vibrator 521 from colliding with each other and adversely affecting the vibration effects of the two on the other hand.
[0030] As described above, the first vibration module and the second vibration module are both movably mounted on the frame 110. Specifically, the first vibration module may include a first vibrator 511 and a first elastic reset member 512, and correspondingly, the second vibration module may include a second vibrator 521 and a second elastic reset member 522. Both the first elastic reset member 512 and the second elastic reset member 522 may be compression springs to ensure that both have good elasticity and relatively low cost.
[0031] As described above, the second vibrator 521 can be clamped between the base 120 and the first magnet 310, and the second vibrator 521 is provided with a mounting hole 5211, and the first vibrator 511 can be at least partially installed in the mounting hole 5211. In this case, specifically, one end of the first elastic return member 512 can be fixedly connected to the base 120, and the other end of the first elastic return member 512 can be fixedly connected to the first vibrator 511, and the first electromagnet 410 can be fixedly connected to the first vibrator 511 by bonding or the like, and then when the first electromagnet 410 drives the first vibrator 511 to move in a direction close to the base 120, the aforementioned first elastic return member 512 is compressed, and conversely, when the first electromagnet 410 drives the first vibrator 511 to move in a direction away from the base 120, the aforementioned first elastic return member 512 is stretched and the first vibrator 511 is restricted from being separated from the base 120. Similarly, the second vibrator 521 in the second vibration module 520 can also be assembled with the frame 110 in a similar manner.
[0032] In another embodiment of the present application, in order to further reduce the difficulty of installing the first vibrator 511 and improve the assembly reliability of the first vibrator 511, a first elastic reset member 512 is provided between the first vibrator 511 and the base 120, and between the first vibrator 511 and the first magnet 310. In this case, when the first electromagnet 410 drives the first vibrator 511 to move toward the base 120, the first elastic reset member 512 between the first vibrator 511 and the base 120 can be compressed. Conversely, when the first electromagnet 410 drives the first vibrator 511 to move away from the base 120, the first elastic reset member 512 between the first vibrator 511 and the first magnet 310 can be compressed. Moreover, in the embodiment of the present application, each first elastic return member 512 can be only clamped between the corresponding two devices, without forming a fixed connection relationship with the corresponding two devices, that is, the first elastic return member 512 between the first vibrator 511 and the base 120 can only form an abutting fit relationship with the first vibrator 511 and the base 120, and accordingly, the first elastic return member 512 between the first vibrator 511 and the first magnet 310 can also only form an abutting fit relationship with the first vibrator 511 and the first magnet 310.
[0033] Correspondingly, in the second vibration module 520, in the first direction, any of the two opposite ends of the second vibrator 521 may be provided with a second electromagnet 420, a second magnet 320, and a second elastic reset member 522 that cooperate with each other. In this case, by using the second elastic reset members 522 provided at the two opposite ends of the second vibrator 521, a relatively stable assembly relationship can be formed between the second vibrator 521 and the frame 110.
[0034] It should be noted that, among the above-mentioned second electromagnet 420, second magnet 320 and second elastic reset member 522 that cooperate with each other, the second electromagnet 420 and the second magnet 320 can cooperate with each other, and when an electric current with alternating direction is passed through the second electromagnet 420, the second magnet 320 and the second electromagnet 420 can be driven to reciprocate towards and away from each other, and as for the second elastic reset member 522, it is used to provide buffering and reset effects for the second vibrator 521.
[0035] Taking one of the two opposite ends of the second vibrator 521 as an example, a specific implementation is that the second magnet 320 is fixedly mounted on the frame 110, and the second electromagnet 420 can be fixedly mounted on the end surface of the second vibrator 521, and the second electromagnet 420 and the second magnet 320 are arranged opposite to each other. At the same time, in this case, the second elastic reset member 522 can be sandwiched between the second magnet 320 and the second electromagnet 420, and by making the second elastic reset member 522 always in a compressed state, it can be ensured that the second elastic reset member 522 can be relatively stably installed between the second magnet 320 and the second electromagnet 420. Alternatively, one of the two opposite ends of the second elastic reset member 522 can also be fixedly connected to the second magnet 320 or the second electromagnet 420, which can also ensure that the second elastic reset member 522 can stably form an assembly relationship with the second vibrator 521.
[0036] In order to improve the assembly stability of the second vibration module 520, in another embodiment of the present application, at least one end of the opposite ends of the second vibrator 521 is provided with a second elastic return member 522 abutting against the frame 110, the second electromagnet 420 is installed on the frame 110, and the coil of the second electromagnet 420 is arranged outside the corresponding second elastic return member 522, and correspondingly, the second magnet 320 is installed on the second vibrator 521.
[0037] In this case, the distance between the second electromagnet 420 and the second magnet 320 disposed at the aforementioned end of the second vibrator 521 is relatively small, and no other devices and structures are sandwiched between the two, and the installation stability of the second elastic reset member 522 can be further improved. Of course, in this case, the second magnet 320 can be located between the second vibrator 521 and the corresponding second elastic reset member 522. In this case, the other end of the second elastic reset member 522 can be abutted against the side surface of the second magnet 320 away from the second vibrator 521. In a further embodiment of the present application, the second elastic reset member 522 disposed at either end of the second vibrator 521 can be abutted against the frame 110, and the corresponding second electromagnet 420 can be installed on the frame 110, and accordingly, the second magnet 320 can be installed on the second vibrator 521.
[0038] As described above, the second elastic reset member 522 may be a compression spring, and considering that the material of the compression spring is usually steel or iron, in order to prevent the second magnet 320 from having an adverse effect on the elastic reset effect of the second elastic reset member 522, in another embodiment of the present application, the second vibrator 521 may be provided with a first receiving groove 5212 and a second receiving groove 5213, and the second magnet 320 may be installed in both the first receiving groove 5212 and the second receiving groove 5213. In this case, since the second magnet 320 is located inside the second vibrator 521, the magnetic effect of the second magnet 320 on the second elastic reset member 522 is relatively weak, so as to ensure that the elastic effect of the second elastic reset member 522 is relatively good. Correspondingly, in this case, the ends of the second elastic reset members 522 facing away from the frame 110 can all be in contact with the second vibrator 521, so that only the second elastic reset member 522 is sandwiched between the second vibrator 521 and the frame 110, so that when the second vibrator 521 is driven by the second electromagnet 420 to vibrate relative to the frame 110, the vibration stability of the second vibrator 521 is relatively higher. Of course, in this embodiment, the second elastic reset member 522 can also be kept in a compressed state all the time, so that the movement stability of the second vibrator 521 relative to the frame 110 is relatively higher.
[0039] As described above, a first elastic return member 512 may be provided between the first vibrator 511 and the base 120 , and between the first vibrator 511 and the first magnet 310 , thereby utilizing the first electromagnet 410 and the at least two groups of first elastic return members 512 to provide a limiting effect on the vibration direction of the first vibrator 511 .
[0040] In order to further improve the accuracy of the vibration direction of the first vibrator 511, optionally, the loudspeaker disclosed in the embodiment of the present application further includes a first slide rail and a first slider, and the first slide rail and the first slider are slidably matched in the thickness direction of the diaphragm 210, that is, the first slide rail extends along the thickness direction of the diaphragm 210, and at least a portion of the first slider extends into the first slide rail, so that both are limitedly matched in the direction perpendicular to the thickness direction of the diaphragm 210. In this case, by setting one of the first slide rail and the first slider on the base 120 and the other on the first vibrator 511, a relatively stable active matching relationship can be formed between the first vibrator 511 and the base 120 in the thickness direction of the diaphragm 210. More specifically, the number of each of the first slide rail and the first slider is multiple, and they are matched one by one. At the same time, the multiple first slide rails can be evenly and spacedly distributed along the direction around the thickness direction of the diaphragm 210, which can further improve the matching stability between the first vibrator 511 and the base 120.
[0041] In a specific embodiment of the present application, the slider can be installed on the base 120. In this case, the length of the slide rail needs to be relatively large, and during the vibration of the first vibrator 511, the slide rail will extend to the side of the base 120 away from the diaphragm 210, that is, the slide rail extends outside the speaker, which is not conducive to the assembly of the speaker.
[0042] To this end, in another embodiment of the present application, the first slide rail can be fixedly mounted on the base 120, and the first slider can be fixedly mounted on the periphery of the first vibrator 511. As described above, in the embodiment of the present application, at least a portion of the first vibrator 511 is disposed in the mounting hole 5211 of the second vibrator 521. In this case, the first slide rail is suspended as a whole. Even if one end of the first slide rail is fixedly connected to the base 120, and the other end of the first slide rail is fixedly connected to the first magnet 310, it is not possible to provide the first slide rail with relatively high assembly stability.
[0043] Based on the above situation, in a further embodiment of the present application, the base 120 of the speaker can include a base 121 and a sleeve 122. In the process of self-assembling the speaker, the base 121 can be installed on one end of the frame 110. At the same time, the sleeve 122 is a closed annular structure, and one end of the sleeve 122 is fixedly connected to the base 120. By making a part of the sleeve 122 extend into the mounting hole 5211, and making a part of the first vibrator 511 extend into the sleeve 122, the sleeve 122 and the first vibrator 511 have a relatively large overlap size in the thickness direction of the diaphragm 210. Then, the first slider or the first slide rail can be set on the inner wall of the sleeve 122. Accordingly, the first slide rail or the first slider is set on the outer wall of the first vibrator 511, so that the assembly stability of the first slide rail and the first slider is relatively high, and the matching effect between the first slide rail and the first slider is also relatively good.
[0044] More specifically, in the embodiment of the present application, the first slider can be fixedly installed on the inner wall of the sleeve 122 at one end away from the seat body 121, that is, the distance between the first slider and the seat body 121 is relatively large. Correspondingly, by forming or fixing the first slide rail on the outer surface of the first vibrator 511, the sliding fit size between the first slider and the first slide rail can be made relatively large.
[0045] Correspondingly, in order to improve the vibration stability of the second vibration module 520, in a further embodiment of the present application, the speaker further includes a second slide rail 611 and a second slider, and the second slide rail 611 and the second slider are slidably matched in the first direction, that is, the second slide rail 611 extends along the first direction, and at least a portion of the second slider extends into the second slide rail 611, so that both are limitedly matched in a direction perpendicular to the first direction. In this case, by setting one of the second slide rail 611 and the second slider on the frame 110 and the other on the second vibration module 520, a relatively stable active matching relationship can be formed between the second vibration module 520 and the base 120 in the thickness direction of the diaphragm 210.
[0046] More specifically, in a direction perpendicular to the first direction and the above-mentioned thickness direction (referred to as the second direction), second slide rails 611 and second sliders can be provided on both sides of the second vibration module 520. Of course, for any of the two sides of the second vibration module 520, multiple second slide rails 611 and second sliders can also be provided to ensure that the matching reliability between the second vibration module 520 and the frame 110 is relatively higher.
[0047] In the embodiment of the present application, as described above, the speaker is generally a cubic structure, and for this purpose, both the second slider and the second slide rail 611 can be provided on the frame 110. Furthermore, the speaker is a rectangular structure, and in this case, the first direction can be the direction of the long side of the speaker to enhance the vibration effect of the second vibration module 520.
[0048] Based on the speaker disclosed in any of the above embodiments, the present application also discloses an electronic device, which includes any of the above speakers. Of course, the electronic device can also generally include other components such as a display screen, a battery, and a camera module. Considering the simplicity of the text, this article will not introduce this in detail.
