Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of an electronic device 100 according to the present application; fig. 2 is a schematic structural diagram of an electronic device 200 according to another embodiment of the present disclosure. Specifically, the electronic apparatus 200 may be any of various types of computer system devices (only one modality is exemplarily shown in fig. 2) that are mobile or portable and perform wireless communication. Specifically, the electronic apparatus 200 may be a mobile phone or a smart phone (e.g., an iPhone (TM) based phone), a Portable game device (e.g., Nintendo DS (TM), PlayStation Portable (TM), game Advance (TM), iPhone (TM)), a laptop, a PDA, a Portable internet appliance, a music player, and a data storage device, other handheld devices, and a headset such as, for example, and the electronic apparatus 200 may also be other wearable devices that require charging (e.g., a Head Mounted Device (HMD) such as an electronic bracelet, an electronic necklace, an electronic device, or a smart watch).

The electronic apparatus 200 may also be any of a number of electronic devices including, but not limited to, a cellular telephone, a smart phone, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, a radio, a medical device, a vehicle transportation device, a computer, a programmable remote control, a pager, a laptop computer, a desktop computer, a printer, a netbook computer, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a moving picture experts group (MPEG-1 or MPEG-2) audio layer 3(MP3) player, a portable medical device, and a digital camera and combinations thereof.

If desired, the electronic apparatus 200 may be a device such as a cellular telephone, media player, other handheld device, wrist watch device, pendant device, earpiece device, or other compact portable device.

With continued reference to fig. 1, the electronic device 100 includes a vibration plate 10, an actuator 20 connected to the vibration plate 10, and a case 30 connected to the actuator 20.

To better explain the improvement point of the present application, first, the structure of the electronic device 100a before the structural improvement is explained. Referring to fig. 3, a schematic structural diagram of an electronic device 100a before structural improvement is shown, in the structure before structural improvement, first, a middle frame 10a is fixed to a vibrating plate 20a, and a gap 12a is formed in the middle frame 10a, then, an exciter 30a is placed in a hole 12a reserved in the middle frame 10a, the exciter 30a includes a stator end 34a and a stator end 36a, wherein the stator end is fixed to the vibrating plate 20a through glue 50a, and the stator end 34a of the exciter 30a is fixed to the middle frame 10a through a fixing lug 32a structure using a bolt 40 a. The stator end 34a and the rotor end 36a of the exciter 30a are of an integrated structure and are not detachable, and after the structure is assembled for the first time, the exciter 30a and the vibrating plate 10a are not easily detached after being cured by glue; disassembly for maintenance is performed if necessary, i.e., the bolt 40a is removed. However, even if the bolt 40a is removed, a part of the center frame 10a is sandwiched between the diaphragm 10a and the fixing lug 32a of the actuator 30a, and thus cannot be removed, and it is difficult to disassemble the center frame. The scheme provided by the application not only has a good fixing effect in structure, but also is convenient to disassemble.

Specifically, the vibration plate 10 may be a display screen or a battery cover, and is not particularly limited herein. The display screen 10 is a component of the electronic device 200 that displays pictures or videos, and the battery cover is sometimes also referred to as a back cover. The vibration plate 10 vibrates with the exciter 20 under the action of the exciter 20, and thus vibration sound emission is realized without opening a sound emission hole on the housing of the electronic device 100.

The exciter 20 serves as a power source for the vibratory sound of the entire electronic device 100. Specifically, a lug 22 is provided on a side of the actuator 20, a part of the lug 22 extends away from the diaphragm 10 to form a fixing member 24, and the fixing member 24 is located above the lug 22 and at a position offset from the center of the lug 22. The exciter 20 is fixedly connected with the vibrating plate 10, so that the exciter 20 vibrates to vibrate and drive the vibrating plate 10 to vibrate, and a sound effect without holes is achieved.

Optionally, in an embodiment, the actuator 20 includes a stator end 26 and a mover end 28, and the mover end 28 is fixedly connected to the vibrating plate 10, for example, fixed by an adhesive layer 29, or fixed by a mechanical structure, which is not limited in this respect. Further, stator end 26 and active cell end 28 set up relatively for stator end 26 and active cell end 28 can produce mutual effort, make active cell end 28 can be close to and keep away from the motion relative to stator end 26, and then make active cell end 28 can drive the vibration board 10 and vibrate relative to stator end 26, and then realize the sclausura sound production. Specifically, the mover end 28 is a magnetic member, and the stator end 26 is a member capable of generating magnetic variation, such as an electromagnetic member or a member including a coil, and currents flowing through the electromagnetic member or the coil in different directions generate magnetic forces corresponding to the mover end 28 and magnetic forces varying back and forth in the same direction and in the opposite direction, so that the mover end 28 can drive the vibration plate 10 to vibrate up and down under the action of the stator end 26.

Specifically, the stator end 26 is a fixed component relative to the housing 30 as long as a varying magnetic force can be generated. Optionally, in an embodiment, the stator end 26 and the mover end 28 form a whole, and the stator end 26 and the mover end 28 are connected through a flexible spring or a deformable adhesive, which provides a vibration space for the vibration of the mover end 28. When the mover end 28 is attracted by the magnetic force generated by the stator end 26 and moves closer to the stator end 26, the flexible spring or the deformable adhesive is compressed, and when the mover end 28 is repelled by the magnetic force generated by the stator end 26, the flexible spring or the deformable adhesive is extended when moving away from the stator end 26. In other embodiments, the stator end 26 and the mover end 28 may be separately disposed, and are not particularly limited herein.

In order to better fix the exciter 20, specifically, the side of the exciter 20 is provided with a lug 22 and a fixing piece 24, the lug 22 and the fixing piece 24 are matched with the shell 30 to realize fixed connection, and the lug 22 is fixed on the side of the stator end 26.

Specifically, the housing 30 is a middle frame, a through hole 32 is formed in the housing 30, the housing 30 is located on one side of the vibration plate 10 close to the exciter 20, and the fixing member 24 penetrates through the through hole 32 of the housing 30 to form a fixed connection with the housing 30, so that a vibration space 40 is formed between the housing 30 and the vibration plate 10. With the above structure, the driver end 28 of the exciter 20 can drive the vibrating plate 10 to vibrate in the vibrating space 40, thereby realizing sound without holes.

With the above structure, firstly, the exciter 20 is fixed to the vibration plate 10, secondly, the through hole 32 of the housing 30 passes through the fixing member 24 and is fixed to the lug 22, and the housing 30 is located on the lug 22. The above structure makes it possible to easily remove the exciter 20 by first loosely removing the case 30 and then performing maintenance on the exciter 20 or further removing the fixing structure between the exciter 20 and the vibration plate 10 if the exciter 20 needs to be removed. The technical problems that a part of the middle frame 10a is clamped between the vibrating plate 20a and the fixing lug of the exciter 30a in the disassembling process before the structure is improved, the middle frame cannot be disassembled and is difficult to disassemble are solved. It can be appreciated that if the exciter 20 is to be removed, the bottom of the exciter 20 needs to be released from the attachment of the vibration plate 10, and that since most of the volume of the exciter 20 is held down by the center frame, the center frame must first be removed to remove the exciter 20. However, in the structure before the structural improvement, the center frame 10a is interposed between the boss 32a of the vibration exciter 30a and the vibration plate 20a, and is difficult to remove. In the structure of the present application, the center frame is not located between the boss 22 of the exciter 20 and the diaphragm 10.

Optionally, in one embodiment, the lug 22, the retainer 24, and the stator end 26 are integrally formed. In other embodiments, other fixing means such as glue may be adopted, and is not limited herein.

Optionally, in one embodiment, the lug 22 includes a first connecting plate 222 and a second connecting plate 224 disposed at an angle to the first connecting plate 222, in one embodiment, at a right angle, as shown in fig. 1. In another embodiment, the angle between the first connecting plate 222 and the second connecting plate 224 may be an obtuse angle, as shown in fig. 4. Specifically, the first connection plate 222 is fixedly connected to the stator end 26. It is to be understood that the terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

For stability of the connection, optionally, in one embodiment, the number of the lugs 22 and the fixing pieces 24 is two, and the two lugs and the fixing pieces are respectively located on two sides of the exciter 20 and are symmetrically arranged relative to the center of the exciter 20. With the above structure, by the arrangement of the symmetrical structure, the firmness and stability of the connection of the exciter 20 and the housing 30 can be further enhanced. In another embodiment, the lugs 22 and the fixing members 24 on both sides of the exciter 20 may not be symmetrical with respect to the center of the exciter 20, and are not particularly limited herein.

Optionally, in an embodiment, the fastening device further includes a nut 50, the fastening device 24 is a threaded column, and the nut 50 is inserted through and locked on the fastening device 24, so as to lock the housing 30 and the lug 22, so that the housing 30 is fixed to the lug 22.

Optionally, to enable the exciter 20 to be more securely coupled to the housing 30, in one embodiment, the nut 50 includes a plurality of nuts 50, two nuts 50 being locked onto each threaded post, thereby further enhancing the security of the coupling. Or one of the threaded columns may lock one nut 50 and the other threaded column may lock two nuts 50, which is not limited herein.

In another embodiment, a glue (not shown) is included at the location where the nut 50 engages the fastener 24. That is, when the locking nut 50 is locked, some glue is infiltrated between the inner surface of the nut 50 and the outer surface of the threaded column, and finally, the glue is solidified to form a glue body, so that the firmness of connection is further enhanced.

It is understood that in other embodiments, the glue may be directly formed between the inner surface of the through hole 32 of the housing 30 and the outer surface of the fixing member 24, without the nut 50, which is not limited herein.

Specifically, the case 30 includes a substrate 34 and an expanded portion 36 extending from an end of the substrate 34 close to the actuator 20 in a direction away from the vibration plate 10, and a bonding portion 38 connected to the expanded portion 36 and extending in parallel to a planar direction in which the vibration plate 10 is located, that is, the substrate 34 is closer to the vibration plate 10 than the bonding portion 38. The via hole 32 is opened in the joint portion 38, the second connection plate 224 is attached to the joint portion 38, and the second connection plate 224 is located between the joint portion 38 and the diaphragm 10. It can be understood that the thickness of the exciter 20 is greater than that of the housing 30, and the second connecting plate 224 is located between the combining portion 38 and the vibrating plate 10, and the combining portion 38 is raised relatively, so that the second connecting plate 224 is disposed between the combining portion 38 and the vibrating plate 10, and the vibrating space 40 is not compressed and cut at the position where the second connecting plate 224 is disposed, thereby avoiding the influence on the vibration sound of the vibrating plate 10 and the mover end 38, and simultaneously ensuring the space above the substrate 34 for disposing other components of the electronic device 200, which provides an advantage for making the electronic device 200 thinner.

Alternatively, in an embodiment, the width of the vibration space between the substrate 34 and the vibration plate 10 is smaller than the width of the vibration space between the second connection plate 224 and the vibration plate 10. By adopting the structure, a plurality of spaces are reserved at the position connected with the second connecting plate 224, so that a larger assembly adjusting space is provided for the size and thickness of the second connecting plate 224, the expansion part 36 and the joint part 38, and the tolerance adaptability is better.

Alternatively, in other embodiments, after the second connecting plate 224 is connected to the joint portion 38, the plane of the second connecting plate 224 near the vibrating plate 10 is flush with the bottom surface of the substrate 34, or even slightly exceeds the bottom surface of the substrate 34, as long as the vibration of the vibrating plate 10 and the actuator end 28 in the actuator 20 is not affected, and is not particularly limited herein.

Alternatively, the vibrating plate 10 may be a display screen or a battery cover of the electronic device 100, and the display screen may be a hard or flexible screen as long as the driving force of the rotor end 28 of the actuator 20 is greater than the bending force of the display screen or the battery cover.

In another embodiment, the mover end may be bonded to a rigid plate, and then the rigid plate is bonded to the vibrating plate, wherein a projection area of the rigid plate on the vibrating plate is larger than a projection area of the actuator on the vibrating plate, thereby enhancing the firmness of the connection between the actuator and the vibrating plate. In other embodiments, the actuator and the vibrating plate may be fixed by a mechanical structure, and are not limited in particular.

Step 102: the housing is assembled to the vibration plate and the exciter such that the fixing member penetrates the hole.
