Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Referring to fig. 1 and fig. 2 together, fig. 1 is a top view of an actuator according to a first embodiment of the present invention; FIG. 2 is a cross-sectional view taken along line I-I of FIG. 1 according to an embodiment. The actuator 100 includes a support member 111, a transparent diaphragm 112, a magnetic member 113, and a coil 114. The transparent diaphragm 112 is fixed to the support member 111. The magnetic member 113 is fixed to the transparent diaphragm 112. The coil 114 is disposed corresponding to the magnetic member 113, and the coil 114 is configured to receive an audio electrical signal, and when the audio electrical signal changes, the transparent diaphragm 112 vibrates. Specifically, the coil 114 receives a varying electrical audio signal and generates a varying magnetic field according to the electrical audio signal, and the magnetic member 113 vibrates under the action of the magnetic field to drive the transparent diaphragm 112 to vibrate.

Specifically, the supporting member 111 is used for supporting the transparent diaphragm 112. The material of the supporting member 111 may be, but is not limited to, an opaque material, such as an opaque resin material, and it is understood that the material of the supporting member 111 may also be, but is not limited to, a transparent material. The supporting member 111 supports the transparent diaphragm 112, and the transparent diaphragm 112 may be, but not limited to, fixed on the supporting member 111 by additionally providing a fixing member, so as to support the transparent diaphragm 112 by the supporting member 111. The fixing part can be but is not limited to optical glue, a fixing hook and the like. The support member 111 supports the transparent diaphragm 112 such that vibratable spaces exist on opposite sides of the diaphragm 112. In other words, the transparent diaphragm 112 and the supporting member 111 together form two sound cavities 10a, and the two sound cavities 10a are respectively located at two sides of the transparent diaphragm 112.

In a possible embodiment, when the material of the support 111 may be, but is not limited to, an opaque material, and an orthographic projection of the support 111 on a plane of the coil 114 at least partially overlaps an orthographic projection of the coil 114 on the plane. When the exciter 100 is applied to a display screen, the phenomenon of poor display quality or display error of the display screen caused by the reflection of light by the coil 114 in the display process of the display screen can be prevented.

Specifically, the transparent diaphragm 112 may be, but not limited to, transparent or translucent, and for example, the material of the transparent diaphragm 112 may be, but not limited to, a thin-film resin material. The transparent diaphragm 112 is transparent or translucent, so the transparent diaphragm 112 has good light transmittance, when the exciter 100 is applied to a display screen, the exciter 100 can be disposed corresponding to a display area of the display screen, and compared with the exciter corresponding to a non-display area of the display screen, the exciter 100 of the present application can increase a screen area ratio of the display screen to which the exciter 100 is applied. Alternatively, the transparent diaphragm 112 may be, but is not limited to, a rectangular film or a circular film.

Specifically, the material of the magnetic member 113 may be, but is not limited to, a material with magnetism, such as metal. The magnetic member 113 may be fixed to the transparent diaphragm 112 by a fixing member. Wherein, the fixing member may be, but is not limited to, an optical glue. The magnetic member 113 is located within the magnetic field generated by the coil 114. In one embodiment, the magnetic member 113 is fixed on a side of the transparent diaphragm 112 facing away from the coil 114. In another embodiment, the magnetic member 113 is embedded in the transparent diaphragm 112, and opposite ends of the magnetic member 113 are respectively exposed on opposite surfaces of the transparent diaphragm 112. In another embodiment, the magnetic element 113 may be fixed on a side of the transparent diaphragm 112 adjacent to the coil 114. When the magnetic member 113 is fixed to the side of the transparent diaphragm 112 adjacent to the coil 114, there are fewer components between the magnetic member 113 and the coil 114, and therefore, the magnetic field generated by the coil 114 is attenuated less to the magnetic member 113, thereby improving the sensitivity of the actuator 100. The following describes a specific manner of fixing the magnetic member 113 to the transparent diaphragm 112.

Referring to fig. 3, fig. 3 is a cross-sectional view taken along line I-I of fig. 1 according to another embodiment. In this embodiment, the actuator 100 further includes a transparent gel 115, and the magnetic element 113 is bonded to the transparent diaphragm 112 through the transparent gel 115. Since the transparent colloid 115 has good light transmittance, the magnetic member 113 in this embodiment is bonded to the transparent diaphragm 112 through the transparent colloid 115, so as to reduce the shielding of the light passing through the transparent diaphragm 112. In this embodiment, the example that the magnetic element 113 is bonded to the side of the transparent diaphragm 112 adjacent to the coil 114 through the transparent colloid 115 is taken as an example, and it can be understood that in other embodiments, the magnetic element 113 is bonded to the side of the transparent diaphragm 112 away from the coil 114 through the transparent colloid 115.

Referring to fig. 4, fig. 4 is a cross-sectional view taken along line I-I of fig. 1 according to another embodiment. In this embodiment, the transparent diaphragm 112 includes a first surface 1121 and a second surface 1122 that are oppositely disposed. In the present embodiment, the first surface 1121 is away from the coil 114 as compared to the second surface 1122. In other embodiments, the first surface 1121 is adjacent to the coil 114 as compared to the second surface 1122. The transparent diaphragm 112 has a through hole 1123 penetrating through the first surface 1121 and the second surface 1122, and the magnetic element 113 is at least partially accommodated in the through hole 1123. Under the condition that the size of the magnetic member 113 is fixed, the magnetic member 113 is at least partially accommodated in the through hole 1123, so that the thickness of the actuator 100 can be reduced, and the screen assembly 10 to which the actuator 100 is applied can be thinned. In the schematic view of the present embodiment, the magnetic member 113 is completely received in the through hole 1123, and two opposite surfaces of the magnetic member 113 are flush with the first surface 1121 and the second surface 1122, respectively. It is understood that in other embodiments, the magnetic member 113 is received in the through hole 1123, one end of the magnetic member 113 protrudes from the first surface 1121, and the other surface of the magnetic member 113 protrudes from the second surface 1122. In other embodiments, the magnetic member 113 is received in the through hole 1123 and partially recessed into the first surface 1121 or the second surface 1122. In this embodiment, the magnetic member 113 is adhered to the side wall of the transparent diaphragm 112 where the through hole 1123 is formed by a transparent adhesive 115.

In this embodiment, the transparent diaphragm 112 includes a first surface 1121 and a second surface 1122 that are oppositely disposed. In the present embodiment, the first surface 1121 is away from the coil 114 as compared to the second surface 1122. In other embodiments, the first surface 1121 is adjacent to the coil 114 as compared to the second surface 1122. The transparent diaphragm 112 has a through hole 1123 penetrating the first surface 1121 and the second surface 1122. The magnetic member 113 includes a body 1131 and a first extension 1132. The body 1131 is partially received in the through hole 1123, the body 1131 partially protrudes from the first surface 1121, and the first extension 1132 is connected to a peripheral edge of a portion of the body 1131 protruding from the first surface 1121. Under the condition that the size of the magnetic member 113 is fixed, the body 1131 of the magnetic member 113 is partially received in the through hole 1123, which can reduce the thickness of the actuator 100, thereby facilitating the reduction of the size of the screen assembly 10 to which the actuator 100 is applied. Further, the first extension portion 1132 is connected to a peripheral edge of a portion of the body 1131 protruding the first surface 1121, so that the magnetic member 113 has a larger volume, and further, the sensitivity of the magnetic member 113 when vibrating under the action of a magnetic field is higher, which is beneficial to improving the sound emitting effect of the exciter 100.

Further, the body 1131 is connected to the sidewall of the transparent diaphragm 112 forming the through hole 1123 by glue, and the first extension 1132 is adhered to the first surface 1121 by glue. Alternatively, the colloid may be a transparent colloid 115. In this embodiment, the bonding area between the magnetic member 113 and the transparent diaphragm 112 is relatively large, which is beneficial to improving the firmness of the bonding between the magnetic member 113 and the transparent diaphragm 112.

Referring to fig. 6, fig. 6 is a cross-sectional view taken along line I-I of fig. 1 according to yet another embodiment. In this embodiment, the transparent diaphragm 112 includes a first surface 1121 and a second surface 1122 that are oppositely disposed. In the present embodiment, the first surface 1121 is away from the coil 114 as compared to the second surface 1122. In other embodiments, the first surface 1121 is adjacent to the coil 114 as compared to the second surface 1122. The transparent diaphragm 112 has a through hole 1123 penetrating the first surface 1121 and the second surface 1122. The magnetic member 113 includes a body 1131 and a first extension 1132. The body 1131 is partially received in the through hole 1123, the body 1131 partially protrudes from the first surface 1121, and the first extension 1132 is connected to a peripheral edge of a portion of the body 1131 protruding from the first surface 1121. Under the condition that the size of the magnetic member 113 is fixed, the body 1131 of the magnetic member 113 is partially received in the through hole 1123, which can reduce the thickness of the actuator 100, thereby facilitating the reduction of the size of the screen assembly 10 to which the actuator 100 is applied. Further, the first extension portion 1132 is connected to a peripheral edge of a portion of the body 1131 protruding the first surface 1121, so that the magnetic member 113 has a larger volume, and further, the sensitivity of the magnetic member 113 when vibrating under the action of a magnetic field is higher, which is beneficial to improving the sound emitting effect of the exciter 100.

Further, the body 1131 is connected to the sidewall of the transparent diaphragm 112 forming the through hole 1123 by glue, and the first extension 1132 is adhered to the first surface 1121 by glue. Alternatively, the colloid may be a transparent colloid 115. In this embodiment, the bonding area between the magnetic member 113 and the transparent diaphragm 112 is large, which is beneficial to improving the firmness of the bonding between the magnetic member 113 and the transparent diaphragm 112.

Further, the body 1131 partially protrudes from the second surface 1122, and the magnetic element 113 further includes a second extension 1133. The second extension portion 1133 is disposed opposite to the first extension portion 1132, and the second extension portion 1133 is connected to the periphery of the portion of the body 1131 protruding from the second surface 1122.

Optionally, the second extension 1133 is adhered to the second surface 1122 by glue. Optionally, the colloid is a transparent colloid 115. In this embodiment, the bonding area between the magnetic member 113 and the transparent diaphragm 112 is large, which is beneficial to improving the firmness of the bonding between the magnetic member 113 and the transparent diaphragm 112.

Referring to FIG. 7, FIG. 7 is a cross-sectional view taken along line I-I of FIG. 1 according to yet another embodiment. In this embodiment, a groove 1124 is formed on the surface of the transparent diaphragm 112, and the magnetic member 113 is disposed in the groove 1124. The transparent diaphragm 112 includes a first surface 1121 and a second surface 1122 which are oppositely disposed. In the present embodiment, the first surface 1121 is away from the coil 114 as compared to the second surface 1122. In other embodiments, the first surface 1121 is adjacent to the coil 114 as compared to the second surface 1122. The groove 1124 may be formed on the first surface 1121 or on the second surface 1122. In the illustration of the present embodiment, the groove 1124 is opened on the second surface 1122. Optionally, the magnetic member 113 is bonded in the groove 1124 by a transparent glue 115. Compared to the transparent diaphragm 112 without the groove 1124, in the present embodiment, the surface of the transparent diaphragm 112 is provided with the groove 1124, the magnetic member 113 is disposed in the groove 124, and under the condition that the size of the magnetic member 113 is fixed, the body 1131 of the magnetic member 113 is partially accommodated in the through hole 1123, so as to reduce the thickness of the exciter 100, thereby facilitating the reduction of the size of the screen assembly 10 applied by the exciter 100.

Referring to fig. 8, fig. 8 is a cross-sectional view taken along line I-I of fig. 1 according to still another embodiment. In the present embodiment, the transparent diaphragms 112 of the plurality of actuators 100 are integrally connected. In this embodiment, the transparent diaphragms 112 are integrally connected, so that the number of manufacturing processes for manufacturing the actuators 100 can be reduced. In the schematic diagram of the present embodiment, the transparent diaphragms 112 of the two actuators 100 are integrally connected as an example. It is to be understood that when the transparent diaphragms 112 of the plurality of actuators 100 are integrally connected, a part of the support member 111 may be shared between adjacent actuators 100. For example, the second support 1112 of one actuator 100 may be the first support 1111 of another actuator 100. In the schematic diagram of this embodiment, the connection relationship between the transparent diaphragms 112 and the magnetic members 113 is illustrated in fig. 7 and the related description thereof, and it can be understood that, when the transparent diaphragms 112 of the multiple actuators 100 are integrally connected, the relationship between the transparent diaphragms 1112 and the magnetic members 113 may be as in any of the previous embodiments. The connection relationship between the transparent diaphragm 112 and the magnetic member 113 in different actuators 100 may be the same or different.

The fixing manner of the magnetic member 113 to the transparent diaphragm 112 is not limited in the present application, as long as the magnetic member 113 is fixed to the transparent diaphragm 112 and the magnetic member 113 is located in the range of the magnetic field generated by the coil 114. In the schematic diagram of the present embodiment, the magnetic member 113 is fixed on a side of the transparent diaphragm 112 adjacent to the coil 114 for illustration.

In a possible manner, referring to fig. 2, 9 and 16, an orthogonal projection of the magnetic member 113 on the plane of the coil 114 falls within an orthogonal projection range of the coil 114 on the plane, and the magnetic member 113 can vibrate within an influence range of a magnetic field generated by the coil 114.

In a possible way, the orthographic projection of the magnetic member 113 on the coil 114 on the plane of the coil 113 falls in the center of the orthographic projection of the coil 114 on the plane. When the orthographic projection of the magnetic member 113 on the plane of the coil 114 on which the coil 113 is located at the center of the orthographic projection of the coil 114 on the plane, the magnetic member 113 is located at the center of the magnetic field of the coil 113, so that the vibration of the magnetic member 113 generated along with the change of the magnetic field generated by the coil 113 is obvious, and the sensitivity of the exciter 100 can be improved.

The specific structure of the supporting member 111 is described in detail below. In one embodiment, the supporting member 111 includes a first supporting body 1111 and a second supporting body 1112. The first supporting body 1111 and the second supporting body 1112 are disposed at an interval, and two opposite ends of the transparent diaphragm 112 are fixed to the first supporting body 1111 and the second supporting body 1112, respectively.

Specifically, the first supporting body 1111 and the second supporting body 1112 are disposed at an interval to form an accommodating space, the transparent diaphragm 112 is located in the accommodating space, and the transparent diaphragm 112 is fixed to the first supporting body 1111 and the second supporting body 1112.

The transparent diaphragm 112 and the support member 111 together form two sound cavities 10a, and the two sound cavities 10a are respectively located at two sides of the transparent diaphragm 112. In a possible implementation manner, the distance from the transparent diaphragm 112 to the two opposite ends of the first supporting body 1111 is not equal to zero, and the distance from the transparent diaphragm 112 to the two opposite ends of the second supporting body 1112 is not equal to zero.

Specifically, the distance from one end of the transparent diaphragm 112 fixed to the first supporting body 1111 to the two opposite ends of the first supporting body 1111 is a first distance and a second distance, respectively, where the first distance is not equal to zero, and the second distance is not equal to zero. The distances from one end of the transparent diaphragm 112 fixed to the second supporting body 1112 to the two opposite ends of the first supporting body 1111 are a third distance and a fourth distance, respectively, where the third distance is not equal to zero, and the fourth distance is not equal to zero. In other words, the position where the transparent diaphragm 112 is fixed to the first support 1111 is not located at the end of the first support 1111, and the position where the transparent diaphragm 112 is fixed to the second support 1112 is not located at the end of the second support 1112.

For the transparent diaphragm 112 disposed at least one end of the first supporting body 1111 and the second supporting body 1112, two opposite sides of the transparent diaphragm 112 in this embodiment may form a vibration space, and when the magnetic member 113 in the exciter 100 drives the transparent diaphragm 112 to vibrate, the transparent diaphragm 112 has enough space to vibrate, so as to improve the sound effect of the exciter 100.

In a possible embodiment, the two sound chambers 10a are equal in space. Specifically, in the case of the transparent film 112 in this embodiment, the distances from one end of the transparent diaphragm 112 fixed to the first support 1111 to the opposite ends of the first support 1111 are equal; the transparent diaphragms 112 are fixed to one end of the second support 1112 and have equal distances from the opposite ends of the second support 1112. It is understood that, for the transparent diaphragm 112 with other structures, the distance from one end of the transparent diaphragm 112 fixed to the first supporting body 1111 to the two opposite ends of the first supporting body 1111 may also be unequal; the distances from one end of the transparent diaphragm 112 fixed to the second support 1112 to the two opposite ends of the second support 1112 may also be equal, as long as the spaces of the two sound cavities 10a are equal.

In other words, the transparent diaphragm 112 is fixed to the middle of the first supporting body 1111, and the transparent diaphragm 112 is fixed to the middle of the second supporting body 1112. The transparent diaphragm 112 in this embodiment is disposed in such a way that the vibration spaces (i.e., the sound cavities 10a) formed on the two opposite sides of the transparent diaphragm 112 are equal, and when the transparent diaphragm 112 vibrates, the sound-generating effect of the exciter 100 can be further improved.

Referring to fig. 9, fig. 9 is a schematic cross-sectional view taken along line I-I of fig. 1 according to yet another embodiment. As shown in the schematic view of the present embodiment, each of the first supporting body 1111 and the second supporting body 1112 includes a first supporting portion 111a and a second supporting portion 111 b. One end of the transparent diaphragm 112 is fixed to a second support portion 111b of the first support body 1111 by a first support portion 111a of the first support body 1111 through an optical glue. The other end of the transparent diaphragm 112 is fixed to a second supporting portion 111b of the second supporting body 1112 through an optical adhesive by a first supporting portion 111a of the second supporting body 1112.

The process of fixing the transparent diaphragm 112 to the first support 1111 and the second support 1112 in the manufacturing method of the actuator 100 will be described in detail below with reference to the actuator 100 described above. Referring to fig. 10 to 13, fig. 10 to 13 are schematic structural diagrams of the transparent diaphragm according to the embodiment of the present invention when the transparent diaphragm is fixed to the first supporting body and the second supporting body. Specifically, the method comprises the following steps.

Step 111, providing two first supporting parts 111a, and arranging the two first supporting parts 111a at intervals, as shown in fig. 10.

Step 121, filling the optical glue 140 on the same side surface of the two first supporting parts 111a, as shown in fig. 11.

Step 131, the transparent diaphragm 112 with the fixed magnetic member 113 is placed on the surface of the side filled with the optical glue 140, as shown in fig. 12.

Step 141, placing two second supporting portions 111b on the surface of the side filled with the optical glue 140 respectively for fixing the transparent diaphragm 112, wherein a first supporting portion 11a and a second supporting portion 111b that are mutually matched and fixed at the same end of the transparent diaphragm 112 form a first supporting member 1111, and a first supporting portion 11a and a second supporting portion 111b that are mutually matched and fixed at the other end of the transparent diaphragm 112 form a second supporting member 1112, as shown in fig. 13.

It is understood that the step of fixing the magnetic member 113 to the transparent diaphragm 112 may be performed before step 131, for example, before step 111, simultaneously with step 111, or after step 111 and before step 121.

Referring to fig. 14, fig. 14 is a schematic structural diagram of an exciter according to a second embodiment of the present application.

In a possible implementation manner, the transparent diaphragm 112 is fixed to the first supporting body 1111 at an equal distance from one end of the first supporting body 1111 to the opposite ends of the first supporting body 1111.

Referring to fig. 15, fig. 15 is a schematic structural diagram of an exciter according to a third embodiment of the present application. The actuator 100 of the present embodiment is substantially the same as the actuator 100 of the first embodiment, except that in the present embodiment, the support 111 includes a first support 1111, a second support 1112, a third support 1113, and a fourth support 1114. The first supporting body 1111 and the second supporting body 1112 are disposed opposite to each other at an interval, the third supporting body 1113 is connected to one end of the first supporting body 1111 and one end of the second supporting body 1112, and the fourth supporting body 1114 is connected to the other end of the first supporting body 1111 and the other end of the second supporting body 1112. In other words, the first support 1111, the third support 1113, the second support 1112, and the fourth support 1114 are sequentially connected to form a hollow frame. Two opposite ends of the transparent diaphragm 112 are respectively fixed to the first supporting body 1111 and the second supporting body 1112. Further, the transparent diaphragm 112 may also be fixed to the third support 1113 and the fourth support 1114.

In this embodiment, the third support 1113 and the fourth support 1114 are further provided between the first support 1111 and the second support 1112, for example, and it is understood that only one third support 1113 for connecting the first support 1111 and the second support 1112 may be provided between the first support 1111 and the second support 1112 in another embodiment.

It is understood that the supporting member 111 in the actuator 100 is not limited to the specific structure of the supporting member 111 described in the above embodiments, as long as it functions to fix the transparent diaphragm 112.

The relationship between the magnetic member 113 and the coil 114 in the actuator 100 will be described below with reference to the actuator 100 provided in each of the foregoing embodiments. Referring to fig. 16, fig. 16 is a bottom view of an actuator according to a third embodiment of the present application. As shown in the schematic diagram of the present embodiment, the orthographic projection of the magnetic member 113 in the plane of the coil 114 falls within the range of the orthographic projection of the coil 114 in the plane. In other words, the magnetic member 113 is located at the very center of the magnetic field generated by the coil 114. When the magnetic member 113 is located at the very center of the magnetic field generated by the coil 114, the magnetic member 113 is sensitive to the magnetic field variation, so that the sensitivity of the actuator 100 can be improved.

Further, an orthographic projection of the support 111 on a plane of the coil 114 at least partially overlaps an orthographic projection of the coil 114 on the plane.

Specifically, the circuit of the coil 114 is a loop structure, the coil 114 receives an audio electrical signal, and the coil 114 generates a magnetic field according to the audio electrical signal. The strength of the magnetic field is related to the magnitude of the audio electric signal, and the changing frequency of the magnetic field is related to the change of the audio electric signal.

In this embodiment, the projection of the single magnetic member 113 on the plane of the coil 114 is located at the center of the projection of the coil 114 on the plane, so as to achieve higher sound volume and sound quality.

Alternatively, the number of the magnetic members 113 on a single transparent diaphragm 112 may be plural without affecting the normal operation of the actuator 100; the magnetic member 113 may be fixed to any position of the transparent diaphragm 112.

The operation of the actuator 100 is explained in detail below. The coil 114 receives the audio electrical signal and generates a magnetic field according to the audio electrical signal, and the magnetic member 113 vibrates under the action of the magnetic field, so as to drive the transparent diaphragm 112 to vibrate. The transparent diaphragm 112 vibrates and the exciter 100 sounds. In a possible embodiment, when the actuator 100 is applied to an electronic device 1, the electronic device 1 includes a processor, and the coil 114 is electrically connected to the processor to receive an audio electrical signal output by the processor. The audio electrical signal is generated by the processor after the audio data (e.g., songs stored in the memory of the electronic device 1) to be played is acquired by the processor.

The present embodiment also provides a screen assembly 10, and the screen assembly 10 provided in the present embodiment is described below with reference to the exciter 100 of the above embodiments. Referring to fig. 17 and 18 together, fig. 17 is a schematic structural diagram of a screen assembly according to an embodiment of the present application; FIG. 18 is a schematic cross-sectional view taken along line II-II of FIG. 17 in accordance with one embodiment. The screen assembly 10 includes a display screen 200 and a plurality of actuators 100, the display screen 200 has a display area 200a, and the plurality of actuators 100 are disposed corresponding to the display area 200 a. The actuator 100 includes a transparent diaphragm 112 and a magnetic member 113. For convenience of illustration, only the screen assembly corresponding to the display area 200a is illustrated in the cross-sectional view of the present embodiment, and the structure of the non-display area portion is not illustrated. The coil 114 receives the variable audio electrical signal and generates a variable magnetic field according to the audio electrical signal, and the magnetic member 113 vibrates under the action of the magnetic field to drive the transparent diaphragm 112 to vibrate. When the transparent diaphragm 113 vibrates, the display screen 200 vibrates to make a sound.

The display area 200a is an area where the display screen 200 displays an image, a video, and the like. The plurality of actuators 100 are disposed corresponding to the display area 200 a. The exciter 100 may be disposed corresponding to the display area 200a of the display screen 200, and may increase a screen ratio of the display screen 200 to which the exciter 100 is applied.

The display screen 200 includes a display body 210 and a cover plate 230, the display body 210 and the cover plate 230 are stacked at intervals, an accommodating space is formed between the display body 210 and the cover plate 230, and at least a part or all of the exciter 100 is disposed in the accommodating space.

Specifically, the material of the cover plate 230 may be, but is not limited to, glass, and on one hand, due to the toughness of glass, the cover plate 230 can protect the display body 210 and the actuator 100 from damage caused by human, external force or force-ineffectiveness; on the other hand, since the glass has good light transmittance, it does not cause poor display quality or erroneous display on the display body 210.

Specifically, the accommodating space is formed between the display body 210 and the cover plate 230, and is used for arranging at least part or all of the structure of the actuator 100, which is easy to implement in terms of production and preparation due to the hierarchy of the structure.

Optionally, the display body 210 further includes a polarizer, and for convenience of description, the polarizer is named as a first polarizer 211. The first polarizer 211 and the cover plate 230 are stacked and spaced, the supporting member 111, the transparent diaphragm 112, and the magnetic member 113 are located between the cover plate 230 and the first polarizer 211, and in this embodiment, the coil 114 is located on a side of the supporting member 111 away from the cover plate 230.

Optionally, the display body 210 further includes a color filter substrate 212, the color filter substrate 212 is disposed on a side of the first polarizer 211 away from the cover plate 230, the color filter substrate 212 and the first polarizer 211 are disposed at an interval, and the coil 114 is disposed on a side of the color filter substrate 212 adjacent to the first polarizer 211.

Specifically, since the magnetic field intensity changes with the change of the distance from the center of the magnetic field under the same magnetic field, the farther the distance from the center of the magnetic field is, the weaker the magnetic field intensity is, the coil 114 is disposed on the side of the color film substrate 212 adjacent to the first polarizer 211, so that the distance from the coil 114 to the magnetic member 113 is shorter, and the purpose that the magnetic member 113 falls within the range of the magnetic field generated by the coil 114 is achieved, and the thickness of the screen assembly 10 applied to the actuator 100 is thinner because the distance from the coil 114 to the magnetic member 113 is shorter.

Optionally, the color filter substrate 212 includes a substrate and a black matrix 2122 distributed in an array. For convenience of distinguishing from the subsequent substrates in the tft array substrate, the substrate in the color filter substrate 212 is named as a first substrate 2121. The black matrix 2122 is disposed on a side of the first substrate 2121 facing away from the cover plate 230, and a projection of the support 111 on the first substrate 2121 at least partially falls within a projection range of the black matrix 2122 on the first substrate 2121.

The display screen 200 needs a backlight module to provide light when operating. When light of the backlight module is emitted to the cover plate 230 through the color film substrate 212, because at least a part of the projection of the support 111 on the first substrate 2121 falls within the projection range of the black matrix 2122 on the first substrate 2121, the support 111 shields the emitted light less or not at all, and therefore, the screen assembly 10 according to the embodiment of the present application can reduce or avoid the reduction of the light transmittance of the display screen 200 caused by the arrangement of the support 111.

The color film substrate 212 further includes a plurality of color resistors 2123 distributed in an array, the black matrix 2122 is disposed between two adjacent color resistors 2123, and an area range of a forward projection of a single transparent diaphragm 112 on the first substrate 2121 covers a forward projection of at least one color resistor 2123 on the first substrate 2121.

Further, the orthographic projection of the black matrix 2122 in the plane of the coil 114 at least partially covers the range of the orthographic projection of the coil 114 in the plane.

When light of the backlight module exits to the cover plate 230 through the color resistors 2123 of the color film substrate 212, since the orthographic projection of the black matrix 2122 in the plane of the coil 114 at least partially covers the orthographic projection range of the coil 114 in the plane, and at least part of the coil 114 is covered by the black matrix 2122, the shielding of the coil 114 on the exiting light is small, even completely, and therefore, the screen assembly 10 according to the embodiment of the present application can reduce or avoid the reduction of the light transmittance of the display screen caused by the arrangement of the coil 114.

Alternatively, as shown in fig. 18, the transparent diaphragms 112 arranged adjacently share at least part of the supporting member 111. It can be understood that, in the manufacturing process, the transparent diaphragm 112 disposed adjacently shares at least part of the supporting member 111, which reduces the waste of raw materials and realizes more efficient production. Of course, the transparent diaphragms 112 adjacently disposed may not share the supporting member 111, which is not limited and required in the embodiments of the present application.

Further, the display body 210 further includes a thin film transistor array substrate 213, a liquid crystal layer 214, and a second polarizer 215. The thin film transistor array substrate 213 is opposite to the color film substrate 212 and is arranged at an interval, and the liquid crystal layer 214 is sandwiched between the thin film transistor array substrate 213 and the color film substrate 212. The second polarizer 215 is disposed on a side of the thin film transistor array substrate 213 facing away from the liquid crystal layer 214. The tft array substrate 213 includes a second substrate 2131 and pixel circuit lines 2132. The pixel circuit lines 2132 are disposed on a surface of the second substrate 2131 adjacent to the liquid crystal layer 214.
