Detailed ways

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described clearly and completely below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1, in a specific working process, the electronic device is equipped with an exciter 101, and the exciter 101 drives the display screen 102 to vibrate, thereby emitting sound. Since the screen sound technology does not need to set a sound device in the display area, it can increase the screen ratio of the electronic device.

In addition to the vibration of the screen sound, the electronic device also needs to vibrate when receiving messages or missed calls during the working process. Based on this, a vibration motor 104 is usually arranged inside the housing 103 of the electronic device, and the vibration motor 104 can generate relatively large vibrations during operation, so as to achieve the purpose of prompting the user. Current electronic equipment is usually equipped with an exciter 101 and a vibration motor 104 at the same time. The exciter 101 and the vibration motor 104 occupy a larger structural space, which makes it difficult to further integrate more functional devices inside the electronic equipment. Especially for 5G devices with more functional devices, because the structural layout space is relatively limited, the simultaneous arrangement of the exciter and the vibration motor increases the difficulty of the structural layout and is not conducive to reducing the cost of the device.

Please refer to FIG. 1 to FIG. 8. An embodiment of the present invention discloses an exciter, and the disclosed exciter can be applied to electronic devices. The disclosed exciter includes a first magnetic component 200 and a second magnetic component 300. The first magnetic component 200 and the second magnetic component 300 are disposed opposite to each other.

The first magnetic assembly 200 includes a bracket 210, a first magnetic member 220, a second magnetic member 230 and a vibrating body 240.

The bracket 210 is a basic component of the first magnetic assembly 200, and other components of the first magnetic assembly 200 can be directly or indirectly mounted on the bracket 210. The bracket 210 may generally be made of a material with higher strength. For example, the bracket 210 may be a metal bracket. In a specific embodiment, the bracket 210 may be a stainless steel bracket.

The vibrating body 240 is a vibrating member capable of vibrating during the working process of the exciter, and the vibrating body 240 is elastically connected to the bracket 210 through the elastic member 250. In order to achieve a better vibration effect, the vibrating body 240 is in a suspended state by the elastic support of the elastic member 250, thereby facilitating the reciprocating vibration described later. In a more preferred solution, the vibrating body 240 can be made of a denser metal, so as to increase the inertia of the vibration process and achieve the purpose of enhancing the vibration effect. In a specific embodiment, the vibrating body 240 may be a metal block, such as an iron block.

The elastic member 250 functions as an elastic connection. Specifically, one end of the elastic member 250 is connected to the bracket 210, and the other end of the elastic member 250 is connected to the vibrating body 240. The elastic member 250 can not only realize the installation of the vibrating body 240, but also the elastic member 250 can elastically restrain the vibrating body 240 during the vibration process of the vibrating body 240. There may be multiple types of the elastic member 250. For example, the elastic member 250 may be a spring, an elastic metal bending sheet, a rubber band, etc. The specific type of the elastic member 250 is not limited in the embodiment of the present invention.

The first magnetic member 220 is disposed on the bracket 210. Specifically, the first magnetic member 220 can be fixed on the bracket 210 to ensure the stability of installation. The second magnetic member 230 is disposed on the vibrating body 240, and the second magnetic member 230 can vibrate with the vibrating body 240. In the same way, the second magnetic member 230 can be fixed on the vibrating body 240.

In the embodiment of the present invention, the first magnetic member 220 and the second magnetic member 230 are both coils, that is to say, the first magnetic member 220 and the second magnetic member 230 can become magnetic structural members in the energized state. The first magnetic member 220 and the second magnetic member 230 are arranged oppositely, so that when the first magnetic member 220 and the second magnetic member 230 are both energized, the first magnetic member 220 and the second magnetic member 230 can interact Electromagnetic field. In this case, since the first magnetic member 220 is set on the bracket 210 and the second magnetic member 230 is set on the vibrating body 240, under the action of the magnetic field force, the vibrating body 240 reciprocates relative to the bracket 210, and the vibrating body 240 performs reciprocating motion, thereby realizing a state of vibration.

Specifically, the first magnetic member 220 may be supplied with an alternating current, so that the first magnetic member 220 generates a variable electromagnetic field, and the second magnetic member 230 will receive a changing magnetic field force in the changing electromagnetic field, and finally drive the vibrating body 240 Perform reciprocating motion.

Under the premise that the exciter disclosed in the embodiments of the present invention is applied to an electronic device, the first magnetic component 200 may be disposed in the housing 500 of the electronic device, and the entire electronic device can be vibrated during the vibration of the vibrating body 240. This vibration can serve as a reminder to the user. For example, when the electronic device receives an incoming call or short message, the vibration of the vibrating body 240 can prompt the user to answer the call or view the short message. Of course, this vibration can also play a role in enhancing the user's experience. For example, the user can vibrate according to different pictures or scenes in a game mode or a movie mode.

In the embodiment of the present invention, the second magnetic component 300 further includes a third magnetic member 310. When the first magnetic member 220 is energized and the second magnetic member 230 is powered off, the third magnetic member 310 and the first magnetic member 220 Cooperate to make the third magnetic member 310 perform reciprocating motion, thereby realizing another kind of vibration.

When the second magnetic member 230 is in the power-off state, the electromagnetic field generated by the second magnetic member 230 disappears. In this case, the first magnetic member 220 is in the energized state, which will not cause the second magnetic member 230 to interact with the first magnetic member 230. The components 220 interact with each other, and accordingly, the vibrating body 240 does not vibrate. Since the first magnetic element 220 is in the energized state, an electromagnetic field can be generated, and the first magnetic element 200 and the second magnetic element 300 are arranged opposite to each other. In this case, the third magnetic element 310 will move under the force of the electromagnetic field, thereby The reciprocating movement of the third magnetic member 310 is realized. In this case, the reciprocating movement of the third magnetic member 310 can generate vibration. Specifically, the first magnetic member 220 is supplied with an alternating current during the working process, thereby forming a changing electromagnetic field. Under the action of the changing electromagnetic field, the third magnetic member 310 is subjected to a changing magnetic field force, thereby achieving the purpose of reciprocating motion. .

The third magnetic member 310 may also be a coil. When the third magnetic member 310 and the first magnetic member 220 are both energized, the electromagnetic field generated by the first magnetic member 220 can act on the third magnetic member 310, thereby realizing the The three magnetic parts 310 generate reciprocating motion. Of course, the third magnetic member 310 may also be a permanent magnet, such as a magnet.

Under the premise that the exciter disclosed in the embodiment of the present invention is applied to an electronic device, the third magnetic member 310 may be connected to the housing 500 or the display screen 100 of the electronic device, and the reciprocating motion of the third magnetic member 310 will drive the housing 500 or the display screen. 100 vibrates, and finally the electronic device can emit sound through the housing 500 or the display screen 100.

The exciter disclosed in the embodiment of the present invention improves the structure of the existing exciter, so that the exciter includes a first magnetic component 200 and a second magnetic component 300 that are arranged oppositely. During operation, the first magnetic component 200 The first magnetic member 220 and the second magnetic member 230 are both in the energized state, so that the second magnetic member 230 drives the vibrating body 240 elastically connected to the bracket 210 to reciprocate to form a kind of vibration. When the first magnetic member 220 is energized, the first magnetic member 220 interacts with the third magnetic member 310 of the second magnetic assembly 300, so that the third magnetic member 310 reciprocates to form another kind of vibration. It can be seen that, compared with the current electronic equipment that needs to be equipped with an exciter and a vibration motor to generate vibrations separately, the exciter disclosed in the embodiment of the present invention can achieve two different situations of vibration. In this case, the electronic equipment does not need to be specially configured for vibration. The configuration of the vibration motor can undoubtedly reduce the occupation of the space in the housing of the electronic device, and at the same time can reduce the manufacturing cost of the electronic device.

In order to avoid electromagnetic interference to other components of the electronic device, in a more preferred solution, the first magnetic component 200 may further include a metal shield 260, a bracket 210, a first magnetic member 220, a second magnetic member 230, and a vibrating body 240. Both the elastic member 250 and the elastic member 250 can be arranged in the metal shield 260. Specifically, the metal shield 260 may be a stainless steel shield. Of course, the metal shield 260 may include an opening 261 facing the second magnetic component 300, so that the electromagnetic interaction between the first magnetic component 200 and the second magnetic component 300 is not affected. Of course, the metal shield 260 can also provide protection for other components arranged inside it.

In the embodiment of the present invention, the shape of the bracket 210 may be various. In a more preferred solution, the bracket 210 may be a ring-shaped structure, and the vibrating body 240 is arranged in the space surrounded by the bracket 210. The bracket 210 can protect the vibrating body 240. At the same time, the space formed by the bracket 210 is more conducive to The vibrating body 240 vibrates in a relatively regular path. In order to improve the effect of the elastic connection, in a more preferred solution, the vibrating body 240 may be elastically connected to the bracket 210 through at least two elastic members 250. The at least two elastic members 250 can improve the elasticity of the connection, thereby ensuring that the vibrating body 240 vibrates more stably. Specifically, the at least two elastic members 250 may be arranged at intervals to improve the balance of the elastic connection. In a specific embodiment, any two adjacent elastic members 250 may be arranged at intervals.

As described above, the first magnetic member 220 is disposed on the bracket 210, and there are many ways to dispose the first magnetic member 220 on the bracket 210. Since the first magnetic element 220 is a coil, in a specific implementation, the first magnetic element 220 may be wound around the outside of the bracket 210. In order to improve the stability of the connection, on the premise that the first magnetic member 220 is wound around the outside of the bracket 210, the first magnetic member 220 and the bracket 210 may be glued together. Of course, it is also possible that the bracket 210 may be provided with a groove, and the first magnetic member 220 may be arranged in the groove of the bracket 210, so as to realize a fixed assembly with the bracket 210. This method can improve the compactness of the assembly. On the premise that the bracket 210 is a ring-shaped structural member, the vibrating body 240 can be arranged in the space surrounded by the bracket 210, since the first magnetic member 220 is wound around the outer side of the bracket 210, and the second magnetic member 230 is provided on the vibrating body 240. Therefore, the second magnetic member 230 can receive a more balanced magnetic field force, so that the vibrating body 240 can achieve a more regular reciprocating motion, thereby improving the vibration effect.

Since the second magnetic member 230 is also a coil, the second magnetic member 230 can also be wound on the vibrating body 240 and located between the vibrating body 240 and the support 210 in the same way. In this manner, when the second magnetic member 230 receives the magnetic field force of the first magnetic member 220, it can drive the vibrating body 240 to vibrate in a more balanced manner. The second magnetic member 230 and the vibrating body 240 can also be connected by bonding, or: the vibrating body 240 can be provided with a groove, and the second magnetic member 230 can be arranged in the groove of the vibrating body 240. This way can Improve the compactness of the assembly.

In order to improve the stability of the elastic connection, in a more preferred solution, an elastic member 250 may be connected between the top end of the vibrating body 240 and the top end of the bracket 210, and the bottom end of the vibrating body 240 and the bottom end of the bracket 210. In this case, both ends of the vibrating body 240 can be elastically restrained by the elastic member 250, so that the stability of vibration can be improved.

In order to avoid electromagnetic interference to other functional devices, in an optional solution, the second magnetic assembly 300 may further include an electromagnetic isolation frame 320, and the third magnetic member 310 is disposed on the electromagnetic isolation frame 320. Specifically, the third magnetic member 310 may be fixed on the electromagnetic isolation frame 320 by bonding, clamping, or the like. Under the premise that the second magnetic assembly 300 is disposed in the housing 500 or the display screen 100 of the electronic device, the third magnetic member 310 can be connected to the housing 500 or the display screen 100 through the electromagnetic isolation frame 320.

The electromagnetic isolation frame 320 can have various structures. As described above, the metal shielding cover 260 may have an opening 261 facing the second magnetic component 300. The electromagnetic isolation frame 320 is connected to the metal shielding cover 260 and is connected to form a shielding space 400. The third magnetic member 310, the bracket 210, the first magnetic member 220, the second magnetic member 230, the vibrating body 240 and the elastic member 250 are all arranged in the shielding space 400, so as to achieve overall electromagnetic shielding.

In order to facilitate installation, in a more preferred solution, the electromagnetic isolation frame 320 and the metal shielding cover 260 may be an integral structure. Of course, the whole formed by the electromagnetic isolation frame 320 and the metal shield 260 is more convenient to install. As shown in FIG. 6, under the premise of being applied to electronic equipment, the above-mentioned exciter can be integrally installed in the inner side of the display screen 100 or in the housing 500 of the electronic equipment through the electromagnetic isolation frame 320 and the metal shielding cover 260.

Of course, in order to facilitate maintenance, in an optional solution, the electromagnetic isolating frame 320 and the metal shielding cover 260 can be detachably connected by means of clamping, screw connection, bonding, and the like. Such an assembly structure facilitates maintenance personnel to open the shielding space 400, and then perform maintenance on the components in the shielding space 400.

In this case, the third magnetic member 310 can drive the display screen 100 or the housing 500 to vibrate, achieving the effect of the display screen 100 or the housing 500 making sounds.

In the electronic device disclosed in the embodiment of the present invention, the exciter may be integrally arranged on the display screen 100, as shown in FIG. 6, or integrally arranged on the housing 500, which has the advantage of convenient installation.

The circuit board (usually the main board of an electronic device) in 500 is electrically connected, and the first magnetic component 200 can be electrically connected to the circuit board in the housing 500 through the first electrical connector 270. In this way, it is possible to prevent the exciter from generating a relatively concentrated force on the display screen 100 or the housing 500. Of course, the second magnetic assembly 300 can also be arranged on the housing 500 and other components to serve as a speaker.

The electronic devices disclosed in the embodiments of the present invention may be mobile phones, tablet computers, e-book readers, game consoles, car navigation systems, wearable devices and other devices.

S101. Receive vibration information.

S102: When the vibration information is the first vibration information, control both the first magnetic member 220 and the second magnetic member 230 to be energized.
