Referring to fig. 1 to 5, the present invention provides a display module 10, which can be applied to a speaker. In an embodiment of the present invention, the display module 10 includes a display housing 11, a display 12 and a sound generating component 13. The display screen 12 is arranged on the display screen shell 11; the sounding component 13 is disposed in the display screen housing 11, the sounding component 13 includes an exciter 131 and a vibration amplifier 135, and the vibration amplifier 135 is connected to the exciter 131 and drives the display screen 12 to vibrate when driven by the exciter 131.

In an embodiment of the present invention, the display housing 11 may be used to mount the display 12 and the sound generating module 13, so that the components of the display module 10 may be assembled into a whole. Meanwhile, the sounding assembly 13 is arranged in the display screen shell 11, and a certain isolation protection effect can be achieved on the sounding assembly through the display screen shell 11, so that the service life of the sounding assembly 13 is prolonged. Moreover, the arrangement can make the installation of the display screen shell 11 more compact, thereby being beneficial to reducing the whole volume of the display module 10. In addition, the display screen housing 11 can also be connected to the sound box body 30 of the sound box, and at this time, a connection structure can be easily arranged on the display screen housing 11. The display screen housing 11 may be a substantially rectangular parallelepiped structure, so that the shape thereof is relatively regular to facilitate the processing and forming thereof, and meanwhile, the display screen housing is adapted to the shape of the display screen 12. Of course, the present application is not limited thereto, and in other embodiments, the display screen housing 11 may also be a square structure or other shape structures. The display screen 12 may display content for viewing by a user. Meanwhile, the display screen 12 can also be driven by the sounding component 13 to vibrate, so that the display screen 12 can sound. The display screen 12 may be embedded in the display screen housing 11 and exposed to the outside. The installation can be made more compact, which is beneficial to further reducing the whole volume of the display module 10. Of course, the present application is not limited thereto, and the display screen 12 may be attached to the outer surface of the display screen housing 11. The display screen 12 may be a rectangular parallelepiped, so that it has a relatively large display area, which is beneficial to improve the light-viewing effect of the user. Of course, the present application is not limited thereto, and in other embodiments, the display screen 12 may be disposed in a square or other shape. In addition, the display screen 12 is a flexible screen so that it can be deformed well to generate sound, and the exciter 131 of the sound generating assembly 13 can be used to provide power to drive the vibration amplifier 135 to vibrate. The actuator 131 may be a piezoelectric ceramic structure or a micro-vibration structure. The exciter 131 may be fixed on the display screen 12 to vibrate the display screen 12 through the vibration amplifier 135. Of course, the present application is not limited thereto, and in other embodiments, the actuator 131 may be fixed to the inner wall of the display screen housing 11. The vibration amplifier 135 can be used to amplify the vibration signal of the actuator 131, so that a relatively loud sound can be clearly generated by the subsequent vibration of the display screen 12 for the user to hear accurately. Specifically, the volume of the actuator 131 is generally set relatively small, resulting in a limited range of its vibration area. The volume of the vibration amplifier 135 may be larger than the volume of the exciter 131, so that when the vibration signal of the exciter 131 is transmitted to the vibration amplifier 135, the vibration amplifier 135 may adjust the vibration signal with a relatively smaller vibration area to a vibration signal with a relatively larger vibration area, so that the sound generating component 13 has a relatively larger vibration area to drive the display screen 12 to generate the vibration sound of the display screen 12. The vibration amplifier 135 may be a plate structure, so that the vibration of the exciter 131 can be efficiently transmitted to the display screen 12 due to its relatively thin thickness. The shape of the vibration amplifier 135 may be rectangular, so that it is relatively regular and easy to machine, and the display screen 12 has a certain vibration area. Of course, in other embodiments, the shape of the vibration amplifier 135 may be square or other shapes. When the vibration amplifier 135 has a relatively good vibration transmission effect, the vibration amplifier 135 may also be a block, so as to ensure that the vibration area thereof is larger than the vibration area of the exciter 131. The vibration amplifier 135 may be made of metal to have a certain strength and to transmit the vibration signal better. Of course, the present application is not limited thereto, and the material of the vibration amplifier 135 may also be plastic with certain strength.

When the display module 10 of the present invention is applied to a sound box, the exciter 131 of the sound generating component 13 in the display module 10 can convert the electrical signal into a vibration signal, and then drive the vibration amplifier 135 to vibrate. The vibration amplifier 135 is larger than the exciter 131 due to its volume, so that the vibration signal of the exciter 131 can be amplified by the vibration amplifier 135 and has a relatively large vibration area with respect to the display screen 12. At this time, the vibration amplifier 135 drives the display screen 12 to vibrate relatively strongly, so that high-frequency sound waves can be radiated outward, and the display module 10 can play high-pitched sound. So compare the audio amplifier in prior art and undertake the playback of high pitch through audio amplifier body 30 for high frequency section sound is sheltered from and is experienced the difference by the high frequency that causes by display module 10. Display module assembly 10 in this scheme makes the audio amplifier can directly undertake the high pitch playback through display module assembly 10, avoids high frequency section sound to be sheltered from by display module assembly 10 and the high frequency that causes experiences poorly to the user obtains better sound and picture and experiences in step. Of course, it should be noted that the display module 10 can also be used to play the middle voice through the sound component 13 when in use. Meanwhile, when the user is in a video call and uses the speaker in a close range, the display module 10 can be switched to the only sounding part in the call mode. Therefore, when a user listens to the sound through the display module 10, the user does not feel that the sound is transmitted from the back of the display module 10, and therefore the speech definition is improved. Moreover, the user can listen to the voice without adjusting the volume to be higher, so that influence on surrounding people is avoided, and the privacy of conversation is improved.

In addition, the sound of the display module 10 in this scheme is generated by driving the vibration amplifier 135 and driving the display screen 12 to vibrate through the exciter 131 of the sound generating assembly 13, so that an excessive opening structure or frame structure does not need to be added on the display screen 12. This is convenient to ensure that the display screen 12 has a relatively large screen ratio, thereby being beneficial to improving the viewing effect of the user using the display module 10. Moreover, the appearance of the display module 10 is relatively beautiful, thereby being beneficial to improving the competitiveness of the product in the market.

Referring to fig. 4 and 5, in an embodiment of the invention, the display module 10 has an up-down direction and a left-right direction perpendicular to the up-down direction, the number of the sound emitting assemblies 13 is two, and the two sound emitting assemblies 13 are respectively located at the left and right sides of the display screen 12.

In this embodiment, when the display module 10 is placed in a normal operation state, it is defined to have a vertical direction and a horizontal direction perpendicular to the vertical direction. At this time, the two sounding assemblies 13 are respectively disposed on the left and right sides of the display screen 12, so that the display screen 12 can be driven to vibrate on the left and right sides to realize that the display module 10 has left and right sound channels. Then, the display module 10 can play different sounds through the left and right sound channels to generate a stereo effect, so as to improve the playing effect of the sound quality and improve the presence of the user. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, one or other numbers of the sound emitting assemblies 13 may be provided.

Please refer to fig. 3, fig. 4 and fig. 5 in an embodiment of the present invention, the display housing 11 includes a front frame 111 and a middle frame 114, the display screen 12 is disposed in the front frame 111, and the front frame 111 is disposed with a light-transmitting portion 112 at a position corresponding to the display screen 12; the screen middle plate 114 is connected to the screen front frame 111 and is matched with the screen front frame 111 to clamp and fix the display screen 12, the vibration amplifier 135 is attached to the inner surface of the display screen 12, and the exciter 131 is attached to the surface of the vibration amplifier 135, which is away from the display screen 12.

In this embodiment, the display screen 12 is clamped and fixed by the front frame 111 and the middle plate 114, so that it is not necessary to provide a connecting structure on the display screen 12 to fix the display screen, which is beneficial to ensuring that the structure of the display screen 12 is not easily affected. In addition, with such an arrangement, after the front frame 111 of the screen and the middle plate 114 of the screen are connected, the three can be installed and fixed at a time, so that the convenience of assembling the display module 10 is improved. The front frame 111 may be provided with a light hole 113 to form a light-transmitting portion 112, or the front frame 111 may be embedded with a transparent material to form the light-transmitting portion 112. And the panel in screen 114 may be located in the front frame 111 of the screen and may be detachably connected to the front frame 111 of the screen. So that it can be disassembled to improve the convenience of product maintenance and replacement. Specifically, the screen middle plate 114 and the screen front frame 111 may be a snap connection, a detachable fixation, a screw connection, or the like. In addition, in order to improve the stability and accuracy of the installation of the display screen 12 between the screen front frame 111 and the screen middle plate 114, the surface of the screen middle plate 114 facing the screen front frame 111 may be provided with a convex ring 115, and the convex ring 115 is arranged around the periphery of the screen middle plate 114 and may abut against the side circumference of the display screen 12.

Referring to fig. 4, 5 and 6 in combination, in an embodiment of the present invention, a surface of the screen middle plate 114 facing the screen front frame 111 is provided with a mounting space 116, and a portion of the vibration amplifying member 135 and the exciter 131 are accommodated in the mounting space 116.

It can be understood that the panel 114 can be accommodated in the mounting space 116, so that the mounting between the panels can be more compact, thereby being beneficial to reduce the overall size of the display module 10. Meanwhile, the installation space 116 may be adapted to the vibration amplifier 135 and/or the exciter 131, so that the installation space 116 may play a certain positioning role thereon, thereby improving the stability of the installation of the sound generating assembly 13, and stably driving the display screen 12 to vibrate. The whole structure of the installation space 116 may be a groove structure recessed on the surface of the screen middle plate 114, or may be a hole structure penetrating through two opposite surfaces of the screen middle plate 114. And when the sounding module 13 is provided with two, the installation space 116 may be correspondingly provided with two.

Referring to fig. 6 to 9 in combination, in an embodiment of the present invention, in a direction in which the panel 114 faces the front frame 111 of the screen, the installation space 116 includes an installation hole 117 and an installation groove 119 which are sequentially communicated, the exciter 131 is accommodated in the installation hole 117, and a portion of the vibration amplifying member 135 is accommodated in the installation groove 119.

It will be appreciated that the mounting space 116 is adapted to be the mounting hole 117 and the mounting groove 119 which are communicated with each other according to different sizes of the exciter 131 and the vibration amplifying member 135, so that the mounting space 116 can be more positioned for the exciter 131 and the vibration amplifying member 135, respectively. Wherein the mounting hole 117 may be provided in a square shape corresponding to the exciter 131, and the mounting groove 119 may be provided in a rectangular shape with respect to the vibration amplifying member 135. The vibration amplifier 135 is partially received in the mounting groove 119, which means that the part of the vibration amplifier 135 facing away from the display screen 12 is located in the mounting groove 119, and the part of the vibration amplifier 135 facing towards the display screen 12 protrudes out of the notch of the mounting groove 119 so as to be attached to the display screen 12. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the installation space 116 may also be a groove body adapted to the shape of the vibration amplifying element 135.

Referring to fig. 7, 8 and 9, in an embodiment of the invention, a limiting arm 118 is disposed at an end of the hole wall of the mounting hole 117 away from the mounting groove 119, a limiting groove 133 is disposed on a surface of the exciter 131 away from the vibration amplifying element 135, and the limiting arm 118 extends into the limiting groove 133 and is in interference fit with the limiting groove 133.

In this embodiment, the limiting arm 118 is in limiting fit with the limiting groove 133, so that the exciter 131 can be more accurately installed at the preset installation position, so as to accurately drive the local area corresponding to the display screen 12 to vibrate. At the same time, the actuator 131 can be restricted from moving in the direction of the side abutted by the stopper arm 188 by the stopper arm 118 abutting against the stopper groove 133 on the actuator 131. For example: a stopper groove 133 is provided on the upper side of the actuator 131, and when the stopper arm 118 abuts against the stopper groove 133, the actuator 131 can be restricted from moving in the upward direction and the leftward and rightward direction, so that the actuator can move only in the direction facing the display screen 12 and in the direction away from the display screen 12 as much as possible. Therefore, in other words, the abutting limit of the limit arm 118 and the limit groove 133 can eliminate some vibration of the exciter 131 in the up-down direction and/or the left-right direction, so that the exciter 131 vibrates substantially in the direction facing the display screen 12 and in the direction away from the display screen 12, thereby reducing the generation of ineffective vibration and facilitating the effective driving of the display screen 12 to vibrate and sound. Wherein, in order to further enhance the limit effect of the limit arm 118 on the actuator 131 in the up-down and left-right directions. The number of the limiting arms 118 may be four, and at this time, the surface of the exciter 131 facing away from the vibration amplifying part 135 is provided with four limiting grooves 133, and the four limiting grooves 133 are respectively located around the exciter 131. By thus engaging a limiting arm 118 with a limiting groove 133, the actuator 131 can be better limited in both the up-down and left-right directions so that it vibrates only in the direction facing the display screen 12 and in the direction away from the display screen. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the number of the limiting arms 118 may be one, two, three, five or more, and the like.

In an embodiment of the present invention, the vibration amplifier 135 is adhesively attached to the display screen 12.

In an embodiment, the vibration amplifier 135 is fixed to the display screen 12 by bonding, so that the vibration amplifier 135 or the display screen 12 does not need to be provided with a corresponding connecting structure to be connected and fixed, and it is favorable for ensuring that the self structures of the vibration amplifier 135 and the display screen 12 are not easily affected. Moreover, so set up and also make vibration amplification piece 135 and display screen 12 have relatively great area of connection, can improve the stability that both connect to be favorable to vibration amplification piece 135 to carry out stable drive to display screen 12. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the vibration amplifier 135 and the display screen 12 may be connected by a snap or fixed in other manners.

In one embodiment of the present invention, the exciter 131 is adhesively secured to the vibration amplifier 135.

In an embodiment, the exciter 131 and the vibration amplifying member 135 are adhesively fixed, so that there is no need to provide a corresponding connecting structure on the exciter 131 or the vibration amplifying member 135 to connect and fix the exciter 131 and the vibration amplifying member 135, thereby being beneficial to ensuring that the structures of the exciter 131 and the vibration amplifying member 135 are not easily affected. Meanwhile, the arrangement enables the exciter 131 and the vibration amplifier 135 to have a relatively large connection area, so that the connection stability of the exciter 131 and the vibration amplifier 135 can be improved, and the driving effect of the exciter 131 on the vibration amplifier 135 is facilitated. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the exciter 131 and the vibration amplifier 135 may be fastened or fixed in other manners by a snap connection.

Referring to fig. 3, fig. 4 and fig. 5, in an embodiment of the invention, the display module 10 further includes a first vibration damping pad 14, and the first vibration damping pad 14 is disposed between the front frame 111 and the display screen 12.

In the present embodiment, the first vibration-damping pad 14 can damp vibration between the display screen 12 and the front frame 111, so as to prevent the vibration on the display screen 12 from being further transmitted to the front frame 111, thereby preventing the front frame 111 from vibrating and interfering with the vibration sound of the display screen 12. Meanwhile, by the arrangement, the display screen 12 can be prevented from being excessively abutted by the screen front frame 111 to be damaged, so that the safety of the display screen 12 in the installation process is improved.
