[0002] Sound boxes are currently widely recognized as the next generation of human-computer interaction interfaces and are expanding into control terminals / interfaces for smart homes. Sound boxes with display screens increase the human-computer interaction experience, and their video call, teaching video watching, and other functions are favored by market consumers. Currently, mid-to-high-end sound boxes are developing towards high sound quality and high screen ratio, but in the actual design process, the display screen often blocks the high sound of the sound box.

[0048] Please refer to Figures 1 to 5 The present application provides a display module 10, which can be applied to a sound box. In an embodiment of the present application, the display module 10 comprises a display screen shell 11, a display screen 12 and a sound generating assembly 13. The display screen 12 is arranged in the display screen shell 11; the sound generating assembly 13 is arranged in the display screen shell 11, and the sound generating assembly 13 comprises an exciter 131 and a vibration amplification piece 135, the vibration amplification piece 135 is connected to the exciter 131 and drives the display screen 12 to vibrate when driven by the exciter 131.

[0049] In an embodiment of the present application, the display screen housing 11 can be used to mount the display screen 12 and the sound production assembly 13, so that the various components of the display module 10 can be assembled to form a whole. At the same time, the sound production assembly 13 is arranged in the display screen housing 11, which can also be isolated and protected by the display screen housing 11, thereby facilitating the extension of the service life of the sound production assembly 13. Moreover, such an arrangement can also make it more compact on the display screen housing 11, thereby facilitating the reduction of the overall volume of the display module 10. In addition, the display screen housing 11 can also be connected with the sound box body 30 of the sound box, at which time the connection structure can be easily arranged on the display screen housing 11. The display screen housing 11 can be generally cuboid in structure, so that its shape is relatively regular and facilitates the improvement of the convenience of its processing and molding, and also facilitates its adaptation 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 can also be square or have other shapes. The display screen 12 can display content for the user to view. At the same time, the display screen 12 can also be driven to vibrate by the sound production assembly 13, thereby realizing the sound production of the display screen 12. The display screen 12 can be embedded in the display screen housing 11 and exposed to the outside. At this time, it can be installed more compactly, thereby facilitating the further reduction of the overall volume of the display module 10. Of course, the present application is not limited thereto, and the display screen 12 can also be attached to the outer surface of the display screen housing 11. The shape of the display screen 12 can also be cuboid, so that it has a relatively large display area, thereby facilitating the improvement of the viewing effect for the user. Of course, the present application is not limited thereto, and in other embodiments, the display screen 12 can also be square or have other shapes. In addition, the display screen 12 is a flexible screen, so that it can better deform and be driven to produce sound. The exciter 131 of the sound production assembly 13 can be used to provide power to drive the vibration amplifier 135 to vibrate. The exciter 131 can be a piezoelectric ceramic structure or a micro-vibration structure. The exciter 131 can be fixed to the display screen 12 to drive the display screen 12 to vibrate through the vibration amplifier 135. Of course, the present application is not limited thereto, and in other embodiments, the exciter 131 can also 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 exciter 131, so that the subsequent driving of the display screen 12 to vibrate can clearly emit a relatively large sound, so as to be accurately heard by the user. Specifically, the volume of the exciter 131 is generally set to be relatively small, which limits the vibration area range.The volume of the vibration amplifier 135 can be set to be larger than that of the exciter 131. Thus, when the vibration signal of the exciter 131 is transmitted to the vibration amplifier 135, the vibration amplifier 135 can adjust the vibration signal with a relatively small vibration area to a vibration signal with a relatively large vibration area, so that the sound production assembly 13 has a relatively large vibration area to drive the display screen 12 to realize the vibration sound production of the display screen 12. The vibration amplifier 135 can be a plate-shaped structure, so that its thickness is relatively thin and the vibration of the exciter 131 can be efficiently transmitted to the display screen 12. The shape of the vibration amplifier 135 can be rectangular, so that it is relatively regular and easy to process and form, and the display screen 12 also has a certain vibration area. Of course, in other embodiments, the shape of the vibration amplifier 135 can be square or other shapes. When the vibration amplifier 135 has a relatively good vibration transmission effect, the vibration amplifier 135 can also be block-shaped, which can ensure that its vibration area is larger than that of the exciter 131. The material of the vibration amplifier 135 can be metal, so as to have a certain strength and better transmit the vibration signal. Of course, the material of the vibration amplifier 135 can also be plastic with a certain strength.

[0050] When the display module 10 of the technical solution of the present application is applied to a sound box, the electric signal can be converted into a vibration signal by the exciter 131 of the sound generating assembly 13 in the display module 10, and then the vibration amplifier 135 is driven to vibrate. The volume of the vibration amplifier 135 is greater than that of the exciter 131, so that the vibration signal of the exciter 131 can be amplified by the vibration amplifier 135, and the vibration area of the display screen 12 is relatively large. At this time, the display screen 12 is driven by the vibration amplifier 135 to vibrate relatively strongly, and high-frequency sound waves can be radiated outward, so that the display module 10 can bear high-frequency playback. Compared with the sound box in the prior art, the sound box bears high-frequency playback through the sound box body 30, so that the high-frequency sound is blocked by the display module 10, resulting in poor high-frequency experience. The display module 10 in the present solution enables the sound box to directly bear high-frequency playback through the display module 10, avoids the high-frequency sound being blocked by the display module 10, and causes poor high-frequency experience, so that the user can obtain better audio-visual synchronization experience. Of course, it should be noted that the display module 10 can also be used to bear medium-frequency playback through the sound generating assembly 13 when in use. At the same time, when the user uses the sound box for video call and close distance, the display module 10 can be switched to the only sound generating component in the call mode. In this way, when the user listens to the sound through the display module 10, he will not feel that the sound comes from behind the display module 10, thereby improving the voice clarity. Moreover, at this time, the user can hear the sound better without adjusting the volume too high, thereby avoiding affecting the surrounding people and improving the privacy of the call.

[0051] In addition, the sound generating of the display module 10 in the present solution is driven by the exciter 131 of the sound generating assembly 13 to drive the vibration amplifier 135 and drive the display screen 12 to vibrate, so that it is not necessary to increase too many opening structures or frame structures on the display screen 12. In this way, it is convenient to ensure that the display screen 12 has a relatively large screen ratio, thereby facilitating to improve the viewing effect of the user using the display module 10. Moreover, at this time, the appearance of the display module 10 is relatively beautiful, thereby facilitating to improve the competitiveness of the product in the market.

[0052] Please refer to Figure 4 and Figure 5 In an embodiment of the present application, the display module 10 has an up-down direction and a left-right direction perpendicular to the up-down direction, and the number of sound generating assemblies 13 is two, and the two sound generating assemblies 13 are respectively located on the left and right sides of the display screen 12.

[0053] In the embodiment, when the display module 10 is in the normal working state, the up-down direction and the left-right direction perpendicular to the up-down direction are defined. At this time, the two sound generating assemblies 13 are arranged 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 produce a stereo sound effect, so as to improve the playing effect of sound quality and improve the user's sense of presence. Of course, it should be noted that the present application is not limited to this, and in other embodiments, the number of sound generating assemblies 13 can also be one or other numbers.

[0054] Please refer to Figure 3 , Figure 4 and Figure 5 In an embodiment of the present application, the display screen housing 11 includes a screen front frame 111 and a screen middle plate 114, the display screen 12 is arranged in the screen front frame 111, the screen front frame 111 is provided with a light-transmitting part 112 at a position corresponding to the display screen 12; the screen middle plate 114 is connected to the screen front frame 111 and cooperates with the screen front frame 111 to clampingly fix the display screen 12, the vibration amplifying member 135 is attached to the inner surface of the display screen 12, and the exciter 131 is attached to the surface of the vibration amplifying member 135 away from the display screen 12.

[0055] In the embodiment, the display screen 12 is clampingly fixed by the cooperation of the screen front frame 111 and the screen middle plate 114, so that a connecting structure does not need to be arranged on the display screen 12 to install and fix it, thereby being beneficial to ensuring that the structure of the display screen 12 is not easily affected. In addition, after the screen front frame 111 and the screen middle plate 114 are connected, the installation and fixing among the three can be completed at one time, thereby being beneficial to improving the convenience of assembling the display module 10. The screen front frame 111 can be provided with a light-transmitting hole 113 to form the light-transmitting part 112, or the screen front frame 111 can be embedded with a transparent material to form the light-transmitting part 112. The screen middle plate 114 can be located in the screen front frame 111 and can be detachably connected to the screen front frame 111, so that it can be detached to improve the convenience of product maintenance and replacement. Specifically, the screen middle plate 114 and the screen front frame 111 can be buckle-connected, detachably fixed, or screw-connected, etc. 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 can be provided with a convex ring 115, which is arranged around the periphery of the screen middle plate 114 and can abut against the side periphery of the display screen 12.

[0056] Please refer to Figure 4 , Figure 5 and Figure 6In an embodiment of the present application, the surface of the screen middle plate 114 facing the screen front frame 111 is provided with a mounting space 116, and part of the vibration amplifier 135 and the exciter 131 are accommodated in the mounting space 116.

[0057] It can be understood that the screen middle plate 114 can be accommodated through the mounting space 116, and the installation between the screen middle plate 114 and the screen front frame 111 can be more compact, so as to facilitate reducing the overall volume of the display module 10. At the same time, the mounting space 116 can be matched with the vibration amplifier 135 and / or the exciter 131, so that the vibration amplifier 135 and / or the exciter 131 can be positioned through the mounting space 116, thereby improving the stability of the sound generating assembly 13, so as to stably drive the display screen 12 to vibrate. The mounting space 116 can be a groove structure recessed on the surface of the screen middle plate 114, or a hole structure penetrating through the two surfaces of the screen middle plate 114. When the sound generating assembly 13 is provided with two, the mounting space 116 can be correspondingly provided with two.

[0058] Please refer to Figures 6 to 9 In an embodiment of the present application, in the direction of the screen middle plate 114 facing the screen front frame 111, the mounting space 116 includes a mounting hole 117 and a mounting groove 119 connected in sequence, the exciter 131 is accommodated in the mounting hole 117, and part of the vibration amplifier 135 is accommodated in the mounting groove 119.

[0059] It can be understood that according to different sizes of the exciter 131 and the vibration amplifier 135, the mounting space 116 is adaptively set as the mounting hole 117 and the mounting groove 119 connected in sequence, so that the mounting space 116 can be positioned with the exciter 131 and the vibration amplifier 135 respectively. The mounting hole 117 can be set as a square corresponding to the exciter 131, and the mounting groove 119 can be set as a rectangle corresponding to the vibration amplifier 135. The part of the vibration amplifier 135 accommodated in the mounting groove 119 means that the part of the vibration amplifier 135 away from the display screen 12 is located in the mounting groove 119, and the part of the vibration amplifier 135 facing the display screen 12 protrudes from the slot 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 to this, and in other embodiments, the mounting space 116 can also be a groove matched with the shape of the vibration amplifier 135.

[0060] Please refer to Figure 7 , Figure 8 and Figure 9In an embodiment of the present application, the hole wall of the mounting hole 117 is provided with a limiting arm 118 at the end away from the mounting groove 119, the exciter 131 is provided with a limiting groove 133 on the surface away from the vibration amplifying member 135, the limiting arm 118 extends into the limiting groove 133 and is in interference fit with the limiting groove 133.

[0061] In the embodiment, the limiting arm 118 and the limiting groove 133 are in limiting fit, so that the exciter 131 can be more accurately installed at the preset mounting position, so as to accurately drive the corresponding local area of the display screen 12 to vibrate. At the same time, the limiting arm 118 abuts against the limiting groove 133 on the exciter 131, which can limit the movement of the exciter 131 in the direction of the side abutted by the limiting arm 188. For example, when the limiting groove 133 is provided on the upper side of the exciter 131 and the limiting arm 118 abuts against the limiting groove 133, the movement of the exciter 131 in the upward direction and the leftward and rightward directions can be limited, so that the exciter 131 moves as much as possible in the direction facing the display screen 12 and the direction away from the display screen 12. Therefore, in other words, the abutment and limiting of the limiting arm 118 and the limiting groove 133 can eliminate some vibrations of the exciter 131 in the upward and / or leftward and rightward directions, so that the exciter 131 basically vibrates in the direction facing the display screen 12 and the direction away from the display screen 12, which reduces the invalid vibration and facilitates effective driving of the display screen 12 to vibrate and make sound. In order to further improve the limiting effect of the limiting arm 118 on the exciter 131 in the upward and leftward and rightward directions, the number of the limiting arms 118 can be four, and the exciter 131 is provided with four limiting grooves 133 on the surface away from the vibration amplifying member 135, and the four limiting grooves 133 are respectively located at the four sides of the exciter 131. In this way, one limiting arm 118 and one limiting groove 133 are in limiting fit, which can better limit the exciter 131 in the upward and leftward and rightward directions at the same time, so that the exciter 131 only vibrates in the direction facing the display screen 12 and the direction away from the display screen 12. Of course, it should be noted that the present application is not limited to this, and in other embodiments, the number of the limiting arms 118 can also be one, two, three, five or more.

The screen back cover 18 covers the side of the screen middle plate 114 away from the display screen 12.

[0073] It can be understood that the screen middle plate 114 has a relatively large area, which can provide a relatively large mounting position for the main board 17, so that the main board 17 with a relatively large volume can be mounted on the screen middle plate 114. At the same time, in this way, the distance between the main board 17 and the exciter 131 is relatively close, which facilitates the connection between the main board 17 and the exciter 131, and can also make the line connecting the two relatively short. Further, after the screen rear shell 18 is covered on the screen middle plate 114, the main board 17 can be hiddenly mounted, reducing the possibility of being damaged by external objects. Further, the main board 17 and the screen middle plate 114, and the screen rear shell 18 and the screen middle plate 114 can be detachably connected, so that when a certain part of the display module 10 is damaged, it can be detached to improve the convenience of product maintenance.

[0074] For reference Figure 1 The present application also provides a sound box, which comprises a sound box body 30 and a display module 10. The specific structure of the display module 10 is referred to the above-mentioned embodiments. Since the sound box adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, the sound box body 30 comprises a sound box shell 31 and a bass speaker 331, the bass speaker 331 is arranged in the sound box shell 31, and the display module 10 is connected to the sound box shell 31. At this time, the bass speaker 331 can be used to undertake the playback of low-frequency sound, and the sound-producing component 13 in the display module 10 can be used to undertake the playback of high-frequency sound, which is equivalent to a tweeter. Further, in order to realize that the display module 10 can rotate following the movement of the user, so that it can better display and / or sound to the user in different directions, the display module 10 can be movably connected to the outside of the sound box shell 31. Specifically, the sound box shell 31 can comprise a fixed part and a rotating part, the rotating part is movably arranged in the fixed part around the up-down direction, and the display module 10 is connected to the rotating part. In this way, when the rotating part is driven to rotate relative to the fixed part, the display module 10 can be driven to rotate. Alternatively, the sound box shell 31 is fixedly arranged as a whole, and the display module is movably connected to the outside of the sound box shell 31, and then rotates relative to the sound box shell 31 around the up-down direction when being driven.

[0075] For reference Figure 10 In an embodiment of the present application, the sound box body 30 further comprises a midrange speaker 333, and the midrange speaker 333 is arranged in the sound box shell 31.

[0076] In the embodiment, the setting of the midrange speaker 333 makes the sound box body 30 capable of playing low frequency sound and midrange sound. The playing function of the sound box body 30 is enhanced, and the all-round playing of low and midrange sound is realized. In addition, based on the structure provided with the midrange speaker 333, the sound emitting component 13 on the display module 10 can be used only for playing high frequency sound, and does not need to play midrange sound. At this time, the midrange and high frequency sound are played by two different sound emitting components, which can facilitate the identification of each sound emitting component to sound frequency band and better emit sound of corresponding sound frequency band. Of course, it should be noted that when the midrange speaker 333 is not provided, the midrange sound can be directly played by the sound emitting component 13 in the display module 10.

[0077] For reference Figure 10 In an embodiment of the present application, the number of bass speakers 331 is one, the bass speaker 331 is arranged at the upper part of the sound box shell 31, and the diaphragm of the bass speaker 331 faces upward; the number of midrange speakers 333 is two, the two midrange speakers 333 are arranged at the lower part of the sound box shell 31 and are respectively located at the two sides of the bass speaker 331, and the diaphragms of the two midrange speakers 333 face the display module.

[0078] In the embodiment, the sound box shell 31 of the sound box body 30 can give a mounting position, so that the bass speaker 331 and the midrange speaker 333 can be better hiddenly mounted in the sound box shell 31 (the sound box shell 31 is correspondingly provided with a sound hole), and meanwhile, the high-frequency sound is not shielded by the display module 10 due to strong directivity. That is, the convenience and compactness of installation are improved under the condition of ensuring the playing effect of the bass speaker 331 and the midrange speaker 333. Moreover, the bass speaker 331 is arranged at the upper part of the sound box shell 31, and the two midrange speakers 333 are arranged at the lower part of the sound box shell 31 and are respectively located at the two sides of the bass speaker 331. The bass speaker 331 and the midrange speaker 333 can be further installed more compactly in the sound box shell 31, thereby facilitating the reduction of the overall volume of the sound box body 30. In addition, the bass speaker 331 of the sound box body 30 mainly focuses on bass playback and is arranged upward, so that the bass effect can be maximally diffused to all directions. The midrange speaker 333 of the sound box body 30 mainly focuses on mid-frequency sound effect playback and is arranged to face the display screen 12, so that the midrange speaker 333 can better sound toward the user during use and can avoid the problem of poor mid-frequency sound vibration characteristics heard by the user due to strong directivity as much as possible. The sound emitting assembly 13 of the display module 10 can mainly focus on high-frequency playback and can directly sound to the user with high quality without being shielded to cause partial high-frequency loss. Therefore, the playback scheme design is helpful to increase the sound field of the sound box, improve the clarity of the sound quality, enhance the richness of the high sound and the directivity, focus the sound on the center of the display screen 12 of the display module 10, and enable the user to enjoy better sound and picture effect.
