Description

Exciter, electronic equipment and control method and device thereof

Technical Field

The present invention relates to the field of communications devices, and in particular, to an exciter, an electronic device, and a method and an apparatus for controlling the same.

Background

With the development of electronic devices, the screen occupation ratio of more and more electronic devices is larger and larger. The larger screen ratio can not only improve the appearance performance of the electronic equipment, but also improve the display performance of the electronic equipment.

The present electronic device usually needs to emit sound during operation, and may be implemented by a sound-emitting device (e.g. a receiver). However, the sound production device occupies a display area of the electronic device, thereby causing the screen occupancy of the electronic device to be affected. Based on this, screen sounding technology is produced. Referring to fig. 1, in a specific operation, the electronic device is provided with an exciter 101, and the exciter 101 drives a display screen 102 to vibrate, thereby emitting sound. The screen sounding technology does not need to arrange sounding devices in the display area, so that the screen occupation ratio of the electronic equipment can be improved.

Besides the vibration required for the screen sound production, the electronic equipment also needs to vibrate when receiving a message, a missed call and the like in the working process. Therefore, the vibration motor 104 is usually disposed inside the housing 103 of the electronic device, and the vibration motor 104 can generate large vibration during operation, thereby achieving the purpose of prompting the user. The current electronic device is usually configured with both the exciter 101 and the vibration motor 104, and the exciter 101 and the vibration motor 104 occupy a larger structural space, thereby making it difficult to further integrate more functional devices inside the electronic device. Especially for 5G equipment with more functional devices, the space of the structural layout is limited, so that the exciter and the vibration motor are arranged at the same time, the difficulty of the structural layout is increased, and the cost of the equipment is not reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

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

Referring to fig. 1-8, an actuator is disclosed in an embodiment of the present invention, and the disclosed actuator can be applied to an electronic device. The disclosed actuator includes a first magnetic assembly 200 and a second magnetic assembly 300. The first magnetic element 200 is disposed opposite to the second magnetic element 300.

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

Wherein the bracket 210 is a basic member 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 be generally made of a material with high strength, for example, the bracket 210 may be a metal bracket, and in a specific embodiment, the bracket 210 may be a stainless steel bracket.

The vibration body 240 is a vibration member capable of generating vibration during the operation of the actuator, and the vibration body 240 is elastically connected to the holder 210 by an elastic member 250. In order to achieve a more excellent vibration effect, the vibration 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 preferred embodiment, the vibrating body 240 may be made of a metal with a relatively high density, so as to increase the inertia of the vibrating process and achieve the purpose of enhancing the vibrating effect. In one specific embodiment, the vibrating body 240 may be a metal block, such as an iron block.

The elastic member 250 plays a role of elastic connection, and 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 vibration body 240. The elastic member 250 not only enables the installation of the vibration body 240, but also the elastic member 250 plays a role of elastically restraining the vibration body 240 during the vibration of the vibration body 240. The elastic member 250 may be various types, for example, the elastic member 250 may be a spring, an elastic metal bending piece, a rubber band, or the like, and the embodiment of the present invention does not limit the specific type of the elastic member 250.

The first magnetic member 220 is disposed on the bracket 210, and specifically, the first magnetic member 220 may be fixed on the bracket 210 to ensure stability of installation. The second magnetic member 230 is disposed on the oscillating body 240, and the second magnetic member 230 can oscillate along with the oscillating body 240. Similarly, the second magnetic member 230 may be fixed to the vibration 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, the first magnetic member 220 and the second magnetic member 230 can become magnetic structures in an energized state. The first magnetic member 220 and the second magnetic member 230 are disposed opposite to each other, so that the first magnetic member 220 and the second magnetic member 230 can generate an electromagnetic field interacting with each other when the first magnetic member 220 and the second magnetic member 230 are both energized, in this case, since the first magnetic member 220 is disposed on the bracket 210 and the second magnetic member 230 is disposed on the vibrating body 240, the vibrating body 240 reciprocates relative to the bracket 210 under the action of the magnetic field force, and the vibrating body 240 reciprocates, thereby realizing vibration in one state.

Specifically, the first magnetic member 220 may be energized with an alternating current, so that the first magnetic member 220 generates a variable electromagnetic field, and the second magnetic member 230 receives a variable magnetic field force in the variable electromagnetic field, and finally drives the vibrating body 240 to reciprocate.

On the premise that the exciter disclosed in the embodiment 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 vibration of the whole electronic device can be realized in the vibration process of the vibration body 240, and the vibration can play a role in reminding a user. For example, when the electronic device receives an incoming call or a short message, the vibration of the vibrating body 240 can prompt the user to answer the call or view the short message. Of course, the vibration can also play a role in enhancing the user 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 assembly 300 further includes a third magnetic member 310, and in a case where the first magnetic member 220 is powered on and the second magnetic member 230 is powered off, the third magnetic member 310 cooperates with the first magnetic member 220 to reciprocate the third magnetic member 310, thereby implementing another vibration.

In the power-off state of the second magnetic member 230, the electromagnetic field generated by the second magnetic member 230 disappears, and in this case, the first magnetic member 220 is in the power-on state, and the second magnetic member 230 does not act on the first magnetic member 220, and accordingly, the vibration body 240 does not vibrate. Since the first magnetic member 220 is in the energized state and can generate an electromagnetic field, and the first magnetic assembly 200 and the second magnetic assembly 300 are disposed opposite to each other, in this case, the third magnetic member 310 moves under the action of the magnetic field force of the electromagnetic field, so as to realize the reciprocating motion of the third magnetic member 310, in this case, the reciprocating motion of the third magnetic member 310 can generate vibration. Specifically, the first magnetic member 220 is energized with an alternating current during operation to form a varying electromagnetic field, and the third magnetic member 310 is subjected to a varying magnetic field force under the action of the varying electromagnetic field to achieve the purpose of reciprocating motion.

The third magnetic member 310 may also be a coil, and when the third magnetic member 310 and the first magnetic member 220 are both in an energized state, the electromagnetic field generated by the first magnetic member 220 may act on the third magnetic member 310, so as to achieve the reciprocating motion of the third magnetic member 310. Of course, the third magnetic member 310 may also be a permanent magnet, such as a magnet.

On 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 third magnetic member 310 reciprocates to drive the housing 500 or the display screen 100 to vibrate, so that the electronic device can finally generate sound through the housing 500 or the display screen 100.

According to the exciter disclosed by the embodiment of the invention, the structure of the existing exciter is improved, so that the exciter comprises the first magnetic component 200 and the second magnetic component 300 which are oppositely arranged, in the working process, the first magnetic component 220 and the second magnetic component 230 in the first magnetic component 200 are both in the energized state, so that the second magnetic component 230 drives the vibrating body 240 elastically connected to the bracket 210 to reciprocate to form vibration, and in the de-energized state of the second magnetic component 230 and the energized state of the first magnetic component 220, the first magnetic component 220 and the third magnetic component 310 of the second magnetic component 300 act, so that the third magnetic component 310 reciprocates to form another vibration. Compared with the conventional electronic equipment which needs to be provided with an exciter and a vibration motor to respectively generate vibration, the exciter disclosed by the embodiment of the invention can realize vibration under two different conditions, and in this condition, the electronic equipment does not need to be provided with the vibration motor specially, so that the occupation of the space in the shell of the electronic equipment can be reduced undoubtedly, and meanwhile, the manufacturing cost of the electronic equipment can be reduced.

In order to avoid electromagnetic interference to other components of the electronic device, in a preferred embodiment, the first magnetic assembly 200 may further include a metal shielding case 260, and the bracket 210, the first magnetic element 220, the second magnetic element 230, the vibration body 240 and the elastic element 250 may be disposed inside the metal shielding case 260. Specifically, the metal shield 260 may be a stainless steel shield. Of course, the metal shield 260 may comprise an opening 261 towards the second magnetic assembly 300 such that electromagnetic interaction between the first magnetic assembly 200 and the second magnetic assembly 300 is not affected. Of course, the metal shield 260 may also provide protection for other components disposed within it.

In embodiments of the present invention, the shape of the stent 210 may be varied. In a preferable embodiment, the support 210 may be an annular structure, the vibration body 240 is disposed in a space surrounded by the support 210, the support 210 can function as a shield for the vibration body 240, and the space formed by the support 210 is more favorable for the vibration body 240 to vibrate along a regular path. In order to improve the effect of the elastic connection, in a preferred embodiment, the vibration body 240 may be elastically connected to the bracket 210 by at least two elastic members 250. The at least two elastic members 250 can increase the elasticity of the connection, thereby ensuring more stable vibration of the vibration body 240. Specifically, the at least two elastic members 250 may be spaced apart from each other, so as to improve the balance of the elastic connection. In a specific embodiment, any two adjacent elastic members 250 may be spaced apart.

As described above, the first magnetic member 220 is disposed on the bracket 210, and the first magnetic member 220 may be disposed on the bracket 210 in various ways. Since the first magnetic member 220 is a coil, in one embodiment, the first magnetic member 220 can be wound around the outer side of the bracket 210. In order to improve the stability of the connection, the first magnetic member 220 may be adhered to the bracket 210 by glue while being wound around the outer side of the bracket 210. Of course, it may also be: the bracket 210 may be provided with a groove, and the first magnetic member 220 may be disposed in the groove of the bracket 210, so as to achieve a fixed assembly with the bracket 210, which can improve the compactness of the assembly. On the premise that the bracket 210 is an annular structural member, the vibrating body 240 may be disposed in a space surrounded by the bracket 210, and since the first magnetic member 220 is disposed around the outer side of the bracket 210 and the second magnetic member 230 is disposed on the vibrating body 240, the second magnetic member 230 may receive a more balanced magnetic field force, so that the vibrating body 240 may perform a more regular reciprocating motion, thereby improving a vibrating effect.

Since the second magnetic member 230 is also a coil, similarly, the second magnetic member 230 can also be wound on the vibrating body 240 and located between the vibrating body 240 and the bracket 210. In this way, the vibrator 240 can be driven to vibrate in a relatively uniform manner when the second magnetic member 230 receives the magnetic force of the first magnetic member 220. The second magnetic member 230 and the vibrator 240 may be bonded to each other, and may be: the vibrator 240 may be provided with a recess, and the second magnetic member 230 may be disposed in the recess of the vibrator 240, in such a manner as to improve the compactness of the assembly.

In order to improve the stability of the elastic connection, in a preferred embodiment, elastic members 250 may be connected between the top end of the vibration body 240 and the top end of the holder 210 and between the bottom end of the vibration body 240 and the bottom end of the holder 210, in which case, both ends of the vibration body 240 may be elastically restrained by the elastic members 250, so that the stability of the vibration may be improved.

In order to avoid electromagnetic interference to other functional devices, in an alternative scheme, 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. On 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 may be connected to the housing 500 or the display screen 100 through the electromagnetic isolation frame 320.

The structure of the electromagnetic isolation frame 320 may be various, as described above, the metal shielding cover 260 may have an opening 261 facing the second magnetic assembly 300, the electromagnetic isolation frame 320 is connected to the metal shielding cover 260 and butted to form the shielding space 400, and the third magnetic member 310, the bracket 210, the first magnetic member 220, the second magnetic member 230, the vibration body 240 and the elastic member 250 are disposed in the shielding space 400, so as to achieve the overall electromagnetic shielding.

For convenience of installation, in a preferred embodiment, the electromagnetic isolation frame 320 and the metal shielding case 260 may be an integral structural member. Of course, the integral body formed by the electromagnetic isolation frame 320 and the metal shielding case 260 is more convenient to install. As shown in fig. 6, in the case of application to an electronic device, the exciter may be mounted inside the display screen 100 or inside the housing 500 of the electronic device through the whole body formed by the electromagnetic isolation frame 320 and the metal shielding case 260.

Of course, in order to facilitate maintenance, in an alternative scheme, the electromagnetic isolation frame 320 and the metal shielding case 260 may be detachably connected by clamping, connecting by a threaded connector, adhering, or the like. This kind of assembly structure makes things convenient for the maintainer to open shielded space 400, and then overhauls the part in shielded space 400.

Based on the exciter disclosed by the embodiment of the invention, the embodiment of the invention discloses electronic equipment, and the disclosed electronic equipment comprises the exciter disclosed by the embodiment.

The electronic device disclosed by the embodiment of the invention may include a housing 500 and a display screen 100 disposed on the housing 500, and the third magnetic member 310 may be disposed on the display screen 100 or a side of the housing 500 facing the first magnetic assembly 200. In this case, the third magnetic member 310 may drive the display screen 100 or the casing 500 to vibrate, so as to achieve the effect of generating sound by the display screen 100 or the casing 500.

In the electronic device disclosed in the embodiment of the present invention, the exciter may be integrally disposed on the display screen 100, as shown in fig. 6, or may be integrally disposed on the housing 500, which has an advantage of convenient installation. Of course, it may also be: the first magnetic assembly 200 is disposed on the housing 500, the second magnetic assembly 300 is disposed on the display screen 100, the second magnetic assembly 300 can be electrically connected to a circuit board (typically, a main board of an electronic device) in the housing 500 of the electronic device through the second electrical connector 330, and the first magnetic assembly 200 can be electrically connected to the circuit board in the housing 500 through the first electrical connector 270. This prevents the actuator from generating concentrated forces on the display screen 100 or the housing 500. Of course, the second magnetic assembly 300 may also be disposed on the housing 500 and other components to act as a speaker.

The electronic device disclosed by the embodiment of the invention can be a mobile phone, a tablet computer, an electronic book reader, a game machine, a vehicle-mounted navigator, a wearable device and the like, of course, the electronic device can be of other types, and the embodiment of the invention does not limit the specific type of the electronic device.

Based on the electronic equipment disclosed by the embodiment of the invention, the embodiment of the invention discloses a control method of the electronic equipment, and the disclosed control method comprises the following steps:

s101, receiving vibration information.

And S102, controlling the first magnetic piece 220 and the second magnetic piece 230 to be electrified under the condition that the vibration information is the first vibration information.

In this step, a central processing unit of the electronic device generally controls the energization of the first magnetic member 220 and the second magnetic member 230. The first vibration information can be information such as incoming calls, short messages and the like.

S103, if the vibration information is the second vibration information, controlling the first magnetic member 220 to be powered on and controlling the second magnetic member 230 to be powered off.

In this step, the second vibration information may be sound emission control information or the like.

In the method for controlling an electronic device according to the embodiment of the present invention, there are various vibration modes of the vibrator 240 and the third magnetic member 310, and the vibration parameters of the vibrator 240 and the third magnetic member may be the same or different. In a specific design process, the vibrating body 240 and the third magnetic member 310 may be designed to generate different vibrations, so as to meet the requirements of some special scenarios.

In an optional scheme, S102 may specifically include: in the case where the vibration information is the first vibration information, both the first magnetic member 220 and the second magnetic member 230 are controlled to be energized, and the vibrator 240 is controlled to vibrate at the first vibration frequency. S103 may specifically include: when the vibration information is the second vibration information, controlling the first magnetic member 220 to be powered on and the second magnetic member 230 to be powered off, and controlling the third magnetic member 310 to vibrate at the second vibration frequency; wherein the first vibration frequency is greater than the second vibration frequency. In a specific operation process, the frequency of the vibrating body 240 is higher than the frequency of the third magnetic member 310, so that the vibrating body 240 vibrates more frequently, in which case, the vibration of the vibrating body 240 may be used as a vibration message for the electronic device to remind the user. The vibration of the third magnetic member 310 may serve as a trigger source for the sound emission of the display screen 100 or the sound emission of the housing 500.

On the premise of the above alternatives, in a further aspect, controlling the vibration body 240 to vibrate according to the first vibration frequency may further include: controlling the vibration body 240 to vibrate within a first amplitude range at a first vibration frequency; meanwhile, the above step of controlling the third magnetic member 310 to vibrate according to the second vibration frequency further includes: controlling the third magnetic member 310 to vibrate within a second amplitude range at a second vibration frequency; wherein the maximum value of the second amplitude range is smaller than the minimum value of the first amplitude range. In a specific working process, the frequency of the vibrating body 240 during vibration is greater than the vibration frequency of the third magnetic member 310, and the amplitude of the vibrating body 240 during vibration is greater than the amplitude of the third magnetic member 310 during vibration, in this case, the vibration of the vibrating body 240 is more obvious and is more suitable for reminding a user of vibration information, and the vibration amplitude generated by the reciprocating motion of the third magnetic member 310 is smaller, so that a large influence on the display screen 100 or the housing 500 can be avoided.

As described above, in a preferred embodiment, the vibration of the vibrating body 240 is suitable as a relatively obvious vibration feedback, and the vibration of the third magnetic member 310 is suitable for a scene in which the vibration is relatively insignificant.

Based on the control method disclosed by the embodiment of the invention, the embodiment of the invention discloses a control device of electronic equipment, and the disclosed vibration device comprises:

and the receiving module is used for receiving the vibration information.

The first control module is used for controlling the first magnetic piece 220 and the second magnetic piece 230 to be electrified under the condition that the vibration information is first vibration information;

and the second control module is used for controlling the first magnetic member 220 to be electrified and controlling the second magnetic member 230 to be powered off under the condition that the vibration information is the second vibration information.

In an alternative scheme, the first control module may control both the first magnetic member 220 and the second magnetic member 230 to be powered on and control the vibrating body 240 to vibrate at a first vibration frequency in the case that the vibration information is the first vibration information; the second control module may control the first magnetic member 220 to be powered on and the second magnetic member 230 to be powered off, and control the third magnetic member 310 to vibrate at a second vibration frequency, when the vibration information is the second vibration information; wherein the first vibration frequency is greater than the second vibration frequency. In a specific operation process, the frequency of the vibrating body 240 is higher than the frequency of the third magnetic member 310, so that the vibrating body 240 vibrates more frequently, in which case, the vibration of the vibrating body 240 is more suitable for being used as vibration information for reminding a user of the electronic device or vibration information for simulating a scene (for example, a game scene). The vibration of the third magnetic member 310 can be used as a trigger source for the display screen to sound or the shell to sound, and is more suitable for a scene with no obvious vibration.

On the premise of the above alternatives, in a further aspect, the first control module may be further configured to control the vibration body 240 to vibrate within a first amplitude range according to a first vibration frequency; the second control module may be further configured to control the third magnetic member 310 to vibrate within a second amplitude range according to a second vibration frequency; wherein the maximum value of the second amplitude range is greater than the minimum value of the second amplitude range. In this case, the vibration of the vibration body 240 is more suitable for an application scenario in which the vibration is significant, and the vibration of the third magnetic member 310 is more suitable for an application scenario in which the vibration is relatively insignificant.
