Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
An embodiment of the present application provides a vibration sound-generating component, and specifically please refer to fig. 1 and fig. 2, where fig. 1 is a first structural schematic diagram of the vibration sound-generating component provided in the embodiment of the present application, and fig. 2 is a structural schematic diagram of a mounting component in the vibration sound-generating component shown in fig. 1 being separated. The vibratory sound assembly 200 includes a display screen 220, a vibratory sound device 240, a center frame 260, and a mount 280.
The display screen 220 includes a display surface 222 and a display back surface 224, which are oppositely disposed, the display surface 222 may be used for displaying contents such as images, and the display back surface 224 is a non-display surface of the display screen 220.
The vibration sounding device 240 is disposed on the display back 224 of the display screen 220, and the vibration sounding device 240 can drive the display screen 220 to vibrate and sound. The vibration sound generating device 240 serves as an actuator for driving the display screen 220 to vibrate, and the display screen 220 serves as a vibrating body for generating sound waves by means of vibration and then transmitting the sound waves to human ears. The vibration sound generating device 240 may be configured to drive the display screen 220 to generate sound in a vibration manner, and the specific implementation manner of the vibration sound generating device 240 is not limited herein. For example, the vibration-producing device 240 may be a piezo-ceramic unit actuator or a micro-vibration unit actuator or other actuator. The vibration sounder device 240 has a first mounting hole 242 on a side facing away from the display screen 220.
The middle frame 260 is disposed on a side of the vibration-sounder device 240 facing away from the display screen 220, and it is also understood that the vibration-sounder device 240 is disposed between the display screen 220 and the middle frame 260. The middle frame 260 has a second mounting hole 262 opposite the first mounting hole 242.
The mounting member 280 is at least partially disposed within the first and second mounting holes 242, 262 and fixedly couples the vibration-producing device 240 to the center frame 260. The first and second mounting holes 242 and 262 are oppositely disposed, and the mounting member 280 may pass through the first and second mounting holes 242 and 262, thereby fixedly coupling the vibration-generating device 240 to the center frame 260.
The vibration sound production device 240 is arranged on the display back 224 of the display screen 220, and the vibration sound production device 240 can directly drive the display screen 220 to produce sound in a vibration mode without being transmitted to the display screen 220 through structures such as the middle frame 260 and the like, so that better acoustic expressive force can be obtained. The vibration sounder 240 is fixedly connected to the middle frame 260 through the mounting member 280, the first mounting hole 242 and the second mounting hole 262, so that the firmness of the vibration sounder 240 can be enhanced, and the display screen 220 cannot be driven to vibrate well due to instability of the vibration sounder. It is also understood that the vibration effect is not weakened due to instability of the display screen, and the vibration sounding effect of the display screen 220 is reduced. In addition, the vibration sound-generating device 240 and the middle frame 260 are fixedly connected through the mounting part 280, when the middle frame 260 needs to be replaced, if the vibration sound-generating device 240 and the middle frame 260 are fixedly bonded, the vibration sound-generating device 240 and the middle frame 260 are difficult to separate, and the vibration sound-generating device 240 and the middle frame 260 are easy to damage during separation, and the vibration sound-generating device 240 and the middle frame 260 can be separated only by detaching the mounting part 280 through fixing through the mounting part 280, so that the middle frame 260 is convenient to replace, and the maintenance cost is reduced.
Specifically, please refer to fig. 3 and 4, fig. 3 is a second structural schematic diagram of the vibration sound-generating component provided in the embodiment of the present application, and fig. 4 is a structural schematic diagram of the vibration sound-generating component and the external component provided in the embodiment of the present application. The pickup through hole 264 is disposed opposite to the vibration generating device 240. No device is disposed in the pickup through hole 264 of the middle frame 260, and the pickup through hole 264 may be used for the external device 300 to pick up the vibration-generating device 240 through the pickup through hole 264. For example, when the vibration-producing device 240 and the middle frame 260 are fixedly connected by the mounting member 280, a force acting on the vibration-producing device 240 is generated, the force is directed toward the display screen 220, the external device 300 picks up the vibration-producing device 240 through the pick-up through hole 264, the external device 300 can provide a pick-up force directed toward the middle frame 260 to the vibration-producing device 240, the pick-up force and the force are opposite, and the pick-up force provided by the external device 300 can enable the mounting member 280 to be better fixedly connected with the middle frame 260.
It should be particularly noted that the display screen 220 is a very fragile device, the vibration sound-generating device 240 is directly disposed on the display back 224 of the display screen 220, if there is no other auxiliary device, the mounting component 280 conducts the acting force generated in the process of fixedly connecting the vibration sound-generating device 240 and the middle frame 260 to the display screen 220, and the acting force is non-uniform, i.e. conducted to a certain position (e.g. top end) of the display screen 220, if the acting force is not controlled well, the display screen 220 is easily broken when the acting force is too large, the acting force is too small, the vibration sound-generating device 240 and the middle frame 260 cannot be connected firmly, during the vibration process of the vibration sound-generating device 240 driving the display screen 220, a part of the vibration energy may be dispersed between the vibration sound-generating device 240 and the middle frame 260, the energy for the vibration sound-generating device 240 driving the display screen 220 to generate sound is insufficient, the, multiple vibrations may further reduce the strength of the connection between the vibration-producing device 240 and the center frame 260, which may also be understood as vibrating the mounting member 280 loose or even vibrating the mounting member 280 off. In this embodiment, the external device 300 picks up the vibration sound production device 240 through picking up the through hole 264, and the picking up force is opposite to the acting force direction, and the mounting member 280 can use great acting force in the installation process, ensures that the vibration sound production device 240 can be firmly connected with the center frame 260, and simultaneously, the picking up force provided by the external device 300 can make the acting force not or rarely conduct to the display screen 220, and the display screen 220 is well protected.
It will be appreciated that a resilient protector (e.g., sponge, foam, etc.) may be provided under the display screen 220 during the process of fixedly attaching the vibration generator device 240 to the bezel 260 by the mounting member 280 to ensure that the display screen 220 is not broken. The external device 300 provides a pick-up force opposite to the force direction through the pick-up through hole 264 without affecting the mounting of the mount 280.
The external device 300 can pick up the vibration generator device 240 by suction, or by other means, such as an adhesive pick-up device, a snap pick-up device, etc.
The number of the second mounting holes 262 on the middle frame 260 may be one or at least two, and when the number of the second mounting holes 262 on the middle frame 260 is at least two, the pick-up through hole 264 is located between at least two of the second mounting holes 262. The first mounting holes 242 of the vibration-sounder device 240 correspond to the second mounting holes 262 one-to-one, that is, the number of the vibration-sounder device 240 is also at least two, and is the same as the number of the second mounting holes 262. The pick-up through hole 264 is positioned between at least two of the second mounting holes 262 to better distribute the pick-up force and facilitate the mounting of the plurality of mounting members 280. It is understood that the pick-up through hole 264 may be located at a central position of at least two second mounting holes 262 for better even distribution of the pick-up force.
The number of the first mounting holes 242 may be two or more, and the following description will take the example where the number of the first mounting holes 242 of the vibration sound generating device 240 is two. The pick-up through hole 264 is located between the two second mounting holes 262 in the orthographic projection of the vibration-producing device so that the pick-up force is better distributed throughout the vibration-producing device 240. The two second mounting holes 262 may be symmetrically disposed with respect to a center line of the sound-emitting device, and the pickup through hole 264 is located between the two second mounting holes 262 in the orthographic projection of the sound-emitting device, so that the pickup force is better and uniformly distributed on the entire sound-emitting device 240. It is understood that the orthographic projection of the pickup through hole 264 on the vibration generating device may be located at the center of the plurality of second mounting holes 262. Illustratively, when the number of the first mounting holes 242 is three, the pickup through hole 264 is located at the center of the three second mounting holes 262 in the orthographic projection of the vibration-generating device. For example, the three second mounting holes 262 are located at three end points of an equilateral triangle, and the orthogonal projection of the pickup through hole 264 on the vibration-producing device is located at the center of the equilateral triangle.
The first mounting hole 242 may be a through hole or a blind hole. For better protection of the display screen 220, the first mounting hole 242 may be a blind hole, and the mounting member 280 cannot penetrate through the first mounting hole 242 to protect the display screen 220. Correspondingly, the second mounting hole 262 is a through hole, and the mounting member 280 passes through the second mounting hole 262 and then passes through the first mounting hole 242, thereby fixedly connecting the vibration-generating device 240 to the center frame 260.
It should be noted that, a screw hole may be provided in the first mounting hole, and the mounting member may be a screw, and the mounting member is fixed to the first mounting hole in a threaded manner after passing through the second mounting hole. The center is including the inner wall that forms the second mounting hole, and the inner wall can have the screw thread also can not have the screw thread, if the inner wall has the screw thread, and the installed part is fixed with the equal spiro union of second mounting hole and first mounting hole, can improve the joint strength between installed part and the center.
The mounting piece, the first mounting hole and the second mounting hole can also be fixedly connected in other modes. Such as by welded, bonded, fastened, etc.
The vibration-producing device 240 is fixedly connected to the display back 224 of the display screen 220, and may be fixed by adhesion, such as by glue or double-sided tape. It can be understood that the vibration sound generating device can be directly adhered and fixed with the display back of the display screen, and some components can be added for fixed connection. If bear the steel sheet, bear the steel sheet and set up between display screen and vibration sound production device, because the demonstration back of display screen is more fragile, when vibration sound production device vibrates, the demonstration back atress of display screen is inhomogeneous to cause the damage easily, can disperse vibration sound production device through bearing the steel sheet and exert the power at the demonstration back, the power that makes the demonstration back of display screen receive is general less, the very big condition of certain point atress can not appear, prevent that the demonstration back of display screen is broken. The area of the bearing steel sheet can be larger than that of the vibration part of the vibration sounding device according to the requirement, and the area of the bearing steel sheet is larger than that of the whole vibration sounding device.
The display screen 220 is attached to the vibration sound generating device 240, the vibration sound generating device 240 and the middle frame 260 are fixed by the mounting part 280, and the vibration sound generating device 240 drives the display screen 220 to vibrate and generate sound.
It can be understood that, since the vibration-sounder device 240 occupies the space of the middle frame 260, the reliability of the middle frame 260 is reduced, and therefore, the attachment of the vibration-sounder device 240 to the display screen 220 needs to be completed first, thereby saving the opening space of the middle frame 260. This results in a blind lock when the middle frame 260 is locked with the vibration sounding device 240, which can also be understood as a situation where there is no way to control or confirm the state of the locked object during the locking process. The vibration sound-generating device 240 is provided with a first mounting hole 242 (e.g., a screw hole), and the mounting member 280 (e.g., a screw) can be locked in, for this operation, an external component (e.g., a suction device) is added, and since the middle of the self-characteristic of the vibration sound-generating device 240 can be extended and retracted, the suction device is used to adsorb the vibration sound-generating device 240 on the middle frame 260 with a certain suction force, and the screw is locked from the middle frame 260 to the vibration sound-generating device 240. In order to ensure the tolerance, the middle frame 260 is positioned and mounted in a high-precision automatic assembly manner (i.e., the middle frame 260 is disposed on one side of the vibration-generating device 240), and the second mounting hole 262 is opened to ensure the margin. The problem of unstable blind lock can be solved. The opening area of the middle frame 260 can be reduced to a greater extent, and only the position of the air suction device needs to be reserved. Simultaneously when the blind lock, because getter device's adsorption affinity makes the holding screw's overdraft more stable, guarantees final locking effect to guarantee the volume production uniformity of the sound production effect of vibration sound production subassembly 200, improve the acoustics expression. If the pulling force for pulling the vibration-generating device 240 to the middle frame 260 is not provided by the suction device, the vibration-generating device 240 may rotate along with the mounting member 280 (e.g., a screw) during locking, which may cause the problems of damage to the vibration-generating device 240, damage to the display screen 220, or improper locking, and the like, and the quality of the product may not be controlled during mass production.
