[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] In the prior art, the centering support plate and the voice coil are bonded together with high-strength glue. However, the glue will evaporate and produce odor, which can easily cause the sound-emitting device to fail in the reliability odor test. At the same time, the odor produced by the glue bonding not only affects the user experience, but also has an impact on the user's health and is not environmentally friendly.

[0045] In order to solve the above problems, the present invention provides a vibration component 1.

[0046] Please combine Figure 2 and Figure 3 ,in, Figure 2 A schematic diagram of the assembly of the vibration component of the sound-emitting unit provided by the present invention; Figure 3 The present invention provides a disassembled schematic diagram of a vibration assembly of a sound-emitting unit. In one embodiment of the present invention, the vibration assembly 1 includes a voice coil 11 and a centering support plate 12. The voice coil 11 is provided with a clamping structure 111 connected to the interior of the voice coil 11. The centering support plate 12 is arranged outside the voice coil 11. The centering support plate 12 is provided with a connecting assembly 121. The connecting assembly 121 includes a connecting plate 122 and a stop plate 123. The opposite ends of the connecting plate 122 are respectively a first end 1221 and a second end 1222. The first end 1221 of the connecting plate 122 is connected to the inner peripheral edge of the centering support plate 12, and the second end 1222 passes through the clamping structure 111 and extends into the interior of the voice coil 11 and is connected to the stop plate 123. The stop plate 123 abuts against the inner wall of the voice coil 11 to be limited in the voice coil 11.

[0047] The technical solution of the present invention is to provide a clamping structure 111 on the voice coil 11 that is connected to the inside of the voice coil 11, and then provide a connecting component 121 on the inner peripheral edge of the centering support plate 12, and a part of the connecting plate 122 of the connecting component 121 and the stop plate 123 are extended into the voice coil 11 through the clamping structure 111, so that the stop plate 123 is tightly fitted against the inner wall of the voice coil 11, thereby generating a limiting force on the voice coil 11 along the radial direction of the voice coil 11, and the connecting plate 122 is in contact with the side wall of the clamping structure 111, thereby generating a limiting force on the voice coil 11 along the axial direction of the voice coil 11. When the voice coil 11 is working, it repeatedly moves along its axial direction. The axial and radial limiting forces generated by the connecting component 121 can ensure that the voice coil 11 will not deviate during axial movement, and at the same time ensure that the centering support plate 12 and the voice coil 11 will not be separated. The present invention realizes the connection between the voice coil 11 and the centering support plate 12 through the cooperation of the connecting component 121 and the clamping structure 111, so that the voice coil 11 and the centering support plate 12 can be fixed without glue. Without glue bonding, no volatile odor will be generated, thereby improving the user experience, without affecting the user's health, and being more environmentally friendly.

[0048] Specifically, each snap-on structure 111 includes a first through hole 112 and a second through hole 113 arranged at intervals along the axial direction of the voice coil 11, the second end 1222 of the connecting plate 122 passes through the first through hole 112 and extends into the interior of the voice coil 11, the stop plate 123 includes a connecting section 1231 and a free section 1232 that are connected to each other, the end of the connecting section 1231 away from the free section 1232 is connected to the second end 1222 of the connecting plate 122, and the end of the free section 1232 away from the connecting section 1231 is inserted into the second through hole 113 and extends out of the voice coil 11. The second end 1222 of the connecting plate 122 passes through the first through hole 112, the free section 1232 passes through the second through hole 113, and the connecting section 1231 between the connecting plate 122 and the free section 1232 abuts against the inner wall of the voice coil 11, so that the connecting assembly 121 abuts against the voice coil 11 at multiple points, thereby improving the locking strength. The first through hole 112 and the second through hole 113 are arranged at intervals along the axial direction of the voice coil 11, so that the voice coil 11 is subjected to two limiting forces along its axial direction, and the free section 1232 reinforces the connecting section 1231. When the voice coil 11 is subjected to a tilting force, the free section 1232 can prevent the connecting section 1231 from being offset and causing the limiting failure of the voice coil 11, thereby preventing the voice coil 11 from tilting, and improving the stability of the voice coil 11 during movement. The setting of two through holes at the same time can effectively reduce the stress concentration phenomenon. The stress borne by the connecting plate 122 and the free section 1232 is dispersed, reducing the stress concentration at a single position, thereby reducing the risk of fatigue and damage of the connecting plate 122 and the free section 1232.

[0049] In one embodiment, an abutment block 124 is provided at one end of the free section 1232 away from the connection section 1231. The abutment block 124 is located outside the voice coil 11 and is used to abut against the outer wall of the voice coil 11 to be limited outside the voice coil 11. The abutment block 124 abuts against the outer wall of the voice coil 11, and again generates a limiting force on the voice coil 11 along its radial direction, further improving the limiting and fixing effect of the connection component 121 on the voice coil 11, improving the stability of the voice coil 11, and preventing the connection component 121 from being separated from the voice coil 11.

[0050] In one embodiment, the connecting plate 122 and the free section 1232 both extend in the radial direction of the voice coil 11 , and the connecting section 1231 and the abutting block 124 both extend in the axial direction of the voice coil 11 . The connecting plate 122 and the free section 1232 both extend in the radial direction of the voice coil 11, so that the connecting plate 122 and the free section 1232 are arranged perpendicular to the voice coil 11, and the limiting force provided by them for the voice coil 11 along its axial direction will not be dispersed due to the angle with the voice coil 11, ensuring that the limiting force generated by the abutment with the voice coil 11 can be completely used to limit the voice coil 11 along the axial direction, thereby improving the fixing effect of the voice coil 11; the connecting section 1231 and the abutment block 124 are similar, the connecting section 1231 and the abutment block 124 extend in the axial direction of the voice coil 11, so that the connecting section 1231 and the abutment block 124 are arranged parallel to the voice coil 11, and the limiting force provided by them for the voice coil 11 along its radial direction will not be dispersed due to the angle with the voice coil 11, ensuring that the limiting force generated by the abutment with the voice coil 11 can be completely used to limit the voice coil 11 along the radial direction, thereby improving the fixing effect of the voice coil 11

[0051] Furthermore, the free section 1232 is connected to the middle of the abutment block 124 , and the connecting section 1231 , the free section 1232 and the abutment block 124 form two clamping grooves 125 spaced apart along the axial direction of the voice coil 11 , and the side walls of the voice coil 11 extend into and are clamped in the two clamping grooves 125 . The free section 1232 is connected to the middle part of the abutment block 124, so that the free section 1232 can form a snap-in groove 125 with the abutment block 124 and the connecting section 1231 on both sides of the axial direction of the voice coil 11, so that the side walls of the voice coil 11 can be snap-fitted with the two snap-in grooves 125 respectively, thereby increasing the number of supporting points for the voice coil 11 and improving the stability of the voice coil 11. The two snap-in grooves 125 are respectively located on both sides of the second through hole 113 along the axial direction of the voice coil, that is, the two snap-in grooves 125 are symmetrically arranged, which can effectively reduce stress concentration. The stress borne by the abutment blocks 124 and the connecting section 1231 on both sides of the second through hole 113 is dispersed, reducing the stress concentration at a single position, thereby reducing the risk of fatigue and damage of the abutment blocks 124 and the connecting section 1231.

[0052] In one embodiment, the dimension of the first through hole 112 along the axial direction of the voice coil 11 is greater than the dimension of the connecting plate 122 along the axial direction of the voice coil 11, so that a first movable gap is formed between the connecting plate 122 and the hole wall of the first through hole 112; and / or, the dimension of the second through hole 113 along the axial direction of the voice coil 11 is greater than the dimension of the free section 1232 along the axial direction of the voice coil 11, so that a second movable gap is formed between the free section 1232 and the hole wall of the second through hole 113.

[0053] It can be understood that the voice coil 11 will repeatedly move along its axial direction during the vibration process, so that a first movable gap and a second movable gap are respectively formed between the connecting plate 122 and the hole wall of the first through hole 112 and between the free section 1232 and the hole wall of the second through hole 113, so that the voice coil 11 has a certain buffer during the movement, avoiding that the voice coil 11 and the centering support plate 12 are completely fixed, resulting in the centering support plate 12 and the voice coil 11 always being subject to the restraining force along their axial direction, which can reduce stress concentration and extend the service life of the voice coil 11 and the centering support plate 12.

[0054] Please combine Figure 2 and Figure 6 ,in, Figure 6 The present invention is a schematic diagram of the top view of the centering support of the sound unit provided by the present invention. In one embodiment, the centering support 12 includes a plurality of bodies 126 arranged at intervals along its circumference, and a connector 127 is connected between any two adjacent bodies 126. Each connector 127 is correspondingly provided with a connecting component 121, and a connecting plate 122 of the connecting component 121 is connected to the inner peripheral edge of the corresponding connecting body 127. A plurality of clip structures 111 are arranged at intervals on the outer periphery of the voice coil 11, and the number of the clip structures 111 is consistent with the number of the connecting components 121 and is arranged one-to-one; in each connecting component 121, the second end 1222 of the connecting plate 122 passes through the corresponding clip structure 111, extends into the interior of the voice coil 11, and is connected to the stop plate 123.

[0055] A connecting component 121 is provided on the inner edges of the multiple connecting bodies 127, and a snap-on structure 111 is provided on the voice coil 11 corresponding to each connecting component 121, so that the voice coil 11 and the centering support plate 12 are fixed by the cooperation of multiple groups of connecting components 121 and the snap-on structure 111, thereby improving the connection stability between the voice coil 11 and the centering support plate 12.

[0056] Furthermore, a plurality of snap-fit ​​structures 111 are evenly spaced along the outer periphery of the voice coil 11, and a plurality of connecting components 121 are evenly spaced along the inner periphery of the centering support 12. The evenly distributed snap-fit ​​structures 111 and connecting components 121 can evenly disperse the mechanical stress of the voice coil 11 during vibration, reduce fatigue damage caused by long-term stress on a single snap-fit ​​structure 111 or connecting component 121, and thus extend the service life of the voice coil 11 and the centering support 12.

[0057] In a specific embodiment, the outer periphery of the connector is connected to the basin frame by fasteners. Figure 1 , Figure 4 and Figure 5 ,in, Figure 4 A schematic diagram of the assembly of the connector of the sound unit and the basin frame provided by the present invention;

[0058] Figure 5 This is a schematic diagram of the disassembly of the connector and the basin frame of the sound unit provided by the present invention. In one embodiment, the outer side of the centering support plate 12 is connected to the basin frame 2, a positioning block 1271 is formed on the outer side of each connector 127, and the basin frame 2 is provided with a positioning hole 26 corresponding to each mounting block. The positioning hole 26 is adapted in shape to the positioning block 1271 and is plug-fitted thereto, and the outer peripheral edge of the connector 127 is fastened to the basin frame 2 by a fastener 27.

[0059] Specifically, the fastener 27 can be a fastener 27 such as a clamp, a bolt, a screw or a nail. A positioning block 1271 is set on the outside of the connecting body 127, and a positioning hole 26 is set on the basin frame 2, so that when the centering support plate 12 and the basin frame 2 are installed, they can be quickly positioned through the cooperation of the positioning hole 26 and the positioning block 1271, thereby improving the assembly efficiency.

[0060] In another specific embodiment, the outer periphery of the centering support piece is engaged with the slot on the basin frame. Figure 1 , Figure 7 and Figure 8 ,in, Figure 7 A schematic diagram of the assembly of the clamping end of the centering support piece of an embodiment of the sound-emitting unit provided by the present invention and the clamping groove of the basin frame 2; Figure 8 The present invention is a disassembly schematic diagram of the clamping end of the centering support piece of an embodiment of the sound-emitting unit provided by the present invention and the clamping groove of the basin frame 2. The present invention also proposes a sound-emitting unit 100, including the basin frame 2 and the above-mentioned vibration component 1, the inner wall of the basin frame 2 is provided with a clamping groove 21, and the notch of the clamping groove 21 is arranged inward; the outer peripheral edge of the centering support piece 12 of the vibration component 1 has a first clamping edge 13, the first clamping edge 13 forms a clamping end, the clamping end extends into the clamping groove 21 and is clamped with the clamping groove 21, a gap 22 is formed between the clamping end and the groove wall of the clamping groove 21, and an elastic buffer pad 3 is provided between the clamping end and the groove wall of the clamping groove 21, and the elastic buffer pad 3 fills the gap 22.

[0061] The technical solution of this embodiment is to provide a slot 21 with an inwardly facing notch on the side of the basin frame 2 facing the centering support piece 12, extend the clamping end formed by the outer peripheral edge of the centering support piece 12 into the slot 21 and engage with the slot 21, and then fill the gap 22 formed by the clamping end and the slot 21 with an elastic buffer pad 3, so that the folding ring and the basin frame 2 can be fixed on the shell without glue, and no volatilization and odor will be generated without glue bonding, thereby improving the user's use experience, without affecting the user's health, and being more environmentally friendly. At the same time, the gap 22 is filled with the elastic buffer pad 3, so that the clamping end of the centering support piece 12 is pressed against the elastic buffer pad 3, and the elastic buffer pad 3 can absorb and buffer the energy transmitted to the basin frame 2 by the centering support piece 12 during the vibration process, prevent the vibration of the centering support piece 12 from being directly transmitted to the basin frame 2, and reduce the distortion caused by resonance.

[0062] In one embodiment, the basin frame 2 is bent inwardly at a position corresponding to the centering support piece 12 to form a mounting platform 23 , and a limit plate 24 is provided on the inner wall of the basin frame 2 near the mounting platform 23 . The limit plate 24 , the mounting platform 23 and the basin frame 2 form a slot 21 .

[0063] The basin frame 2 is bent inward to form a mounting platform 23, and the mounting platform 23, the basin frame 2 and the limiting plate 24 form a card slot 21. It can be understood that the mounting platform 23 and the limiting plate 24 are mainly used to abut against the card-connecting end. The arrangement of the mounting platform 23 and the limiting plate 24 increases the contact area between the card-connecting end of the centering support piece 12 and the card slot 21, thereby improving the card-connection stability of the centering support piece 12 and the basin frame 2.

[0064] In one embodiment, the gap 22 includes a first gap 221, a second gap 222 and a third gap 223 which are connected in sequence, and the elastic buffer pad 3 includes a first buffer segment 31, a second buffer segment 32 and a third buffer segment 33. The first buffer segment 31, the second buffer segment 32 and the third buffer segment 33 are connected or abutted in sequence to form a U-shaped elastic buffer pad 3 with an opening facing inward, and the first buffer segment 31, the second buffer segment 32 and the third buffer segment 33 are filled in the first gap 221, the second gap 222 and the third gap 223 respectively and one by one.

[0065] Three gaps 22 connected in sequence form a U-shaped gap 22, and the three gaps 22 connected in sequence correspond to the three side wall surfaces of the clamping end for connecting with the clamping slot 21, and the first buffer segment 31, the second buffer segment 32 and the third buffer segment 33 of the elastic buffer pad 3 are respectively filled in the first gap 221, the second gap 222 and the third gap 223 one by one, so that each surface of the clamping end can be absorbed and alleviated by the elastic buffer pad 3, further reducing the transmission of mechanical vibration and preventing the noise caused by resonance or vibration of the basin frame 2.

[0066] In one embodiment, the outer wall of the first buffer section 31 and / or the outer wall of the second buffer section 32 and / or the outer wall of the third buffer section 33 is provided with a fastening member 34 , and the fastening member 34 is used to fasten against the slot wall of the corresponding slot 21 .

[0067] A fastening piece 34 is provided on the outer wall of at least one of the first buffer section 31, the second buffer section 32 and the third buffer section 33. The elastic buffer pad 3 is squeezed and limited in the gap 22 by the clamping end and the clamping slot 21, but it is not tightly fitted everywhere. Therefore, the fastening piece 34 is used to improve the abutment tightness between the elastic buffer pad 3 and the clamping slot 21 to prevent the elastic buffer pad 3 from deviating or falling out of the gap 22, thereby ensuring the buffering effect of the elastic buffer pad 3.

[0068] In one embodiment, an outer wall of the first buffer section 31 is provided with an abutting groove 341 to form a clamping member 34, and a slot wall of the slot 21 is formed with an abutting protrusion 25 that abuts against the abutting groove 341; and / or, an outer wall of the second buffer section 32 is provided with a second protrusion 342 to form a clamping member 34; and / or, an outer wall of the third buffer section 33 is provided with a third protrusion 343 to form a clamping member 34.

[0069] An abutment groove 341 is provided on the first buffer section 31, and an abutment protrusion 25 is provided on the groove wall of the card slot 21. On the one hand, the first buffer section 31 can be limited and fixed by the plug-in cooperation between the abutment groove 341 and the abutment protrusion 25, and on the other hand, it is convenient for positioning during the installation process to improve the assembly efficiency and assembly accuracy; a second protrusion 342 is provided on the second buffer section 32 to press the second buffer section 32 against the groove wall of the card slot 21, and a third protrusion 343 is provided on the third buffer section 33 to press the third buffer section 33 against the groove wall of the card slot 21, thereby improving the abutment tightness and preventing the elastic buffer pad 3 from being offset or falling off outside the gap 22, thereby ensuring the buffering effect of the elastic buffer pad 3.

[0070] It should be noted that not all the first buffer segment 31, the second buffer segment 32 and the third buffer segment 33 need to be provided with a clamping member 34. For the sake of convenience, the first buffer segment 31, the second buffer segment 32 and the third buffer segment 33 are all referred to as buffer segments. According to actual needs, a clamping member 34 can be provided in the buffer segment with insufficient abutment tightness. If the tightness of a buffer segment itself with the card slot 21 and the card connection end has reached the requirement, there is no need to provide a clamping member 34, so as to improve production efficiency and reduce production costs.

[0071] In a specific embodiment, the first buffer section 31, the second buffer section 32 and the third buffer section 33 are integrally formed flexible pads. The first buffer section 31, the second buffer section 32 and the third buffer section 33 are integrally formed U-shaped flexible pads. When installing, first put the elastic buffer pad 3 into the card slot 21, and then extend the clamping end into the opening formed by the elastic buffer pad 3, so that the three outer wall surfaces of the clamping end are respectively pressed against the first buffer section 31, the second buffer section 32 and the third buffer section 33, thereby improving the convenience of installation and assembly efficiency.

[0072] See also Fig. 9 , Fig. 9 The present invention is a schematic diagram of the assembly of the clamping end of the centering support piece of another embodiment of the sound unit provided by the present invention and the clamping groove of the basin frame. In another specific embodiment, the first buffer section 31 and the second buffer section 32 are flexible pads that are integrally formed, and the third buffer section 33 is a pressing block 35. The pressing block 35 is a hard pad, and the pressing block 35 abuts against one end of the second buffer section 32 away from the first buffer section 31, and flexible gaskets 351 are provided on opposite sides of the pressing block 35.

[0073] In the card slot 21 corresponding to the centering support piece 12, a flexible gasket 351 is provided on one side where the pressing block 35 abuts against the first card edge 13 and on one side where the pressing block 35 abuts against the slot wall of the card slot 21, respectively. In the card slot 21 corresponding to the second connecting portion, a flexible gasket 351 is provided between the pressing block 35 and the corresponding slot wall of the card slot 21 and between the pressing block 35 and the second connecting portion.

[0074] The hard pressing block 35 is abutted against the second connection part of the folding ring, and the second connection part is pressed against the clamping edge by the pressing block 35. Compared with the flexible pad, the hard pad can increase the connection strength and stability between the second connection part and the clamping slot 21, ensure the accurate positioning of the folding ring and the basin frame 2, and the accurate positioning between the centering support 12 and the basin frame 2, thereby avoiding looseness or displacement and maintaining the long-term stability of the sound unit 100. The hard pad can also ensure the tight fit between the clamping end and the clamping slot 21, improve the accuracy during the installation process, and avoid unstable connection caused by tolerance or installation error. A flexible pad 351 is padded between the pressing block 35 and the groove wall of the clamping slot 21 and between the pressing block 35 and the second connection part. The flexible pad 351 absorbs and alleviates the vibration from the folding ring, the basin frame 2 or the centering support 12, which helps to prevent the vibration from being transmitted to the housing or the basin frame 2, reduce the resonance of the housing and the basin frame 2, reduce distortion and noise, and thus improve the sound quality of the sound unit 100.
