Rather, the scope of the descriptions is to be accorded the broadest interpretation so as to encompass all similar technologies and alternatives based on the teachings herein.

[0042] Furthermore, described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the

[0043] The application is further described below with reference to the drawings and specific examples. It is to be understood that the specific examples described below are merely exemplary and are not intended to limit the scope of the application. The following examples are provided to further illustrate the application and are not intended to limit the scope of the application.

[0044] The present disclosure provides a pressing device configured to press a to-be-pressed region of a to-be-pressed piece.

[0045] In combination Figures 1 to 4 As shown in the figure, the pressing device can include a base 10 and a pressing mechanism. The base 10 can be configured to support the to-be-pressed piece 11. The pressing mechanism can include a driving assembly 12, a first pressing assembly 13a and a second pressing assembly 13b. The driving assembly 12 is connected with the first pressing assembly 13a and the second pressing assembly 13b, and the first pressing assembly 13a and the second pressing assembly 13b correspond to different regions of the base 10, so that after the to-be-pressed piece 11 is placed on the base 10, the first pressing assembly 13a and the second pressing assembly 13b can correspond to different regions of the to-be-pressed piece 11, that is, the pressing device of the present embodiment can be adapted to the to-be-pressed piece 11 which has at least two regions to be pressed.

[0046] For example, in the pressing mechanism, the number of pressing assemblies is not limited to two, but can also be three, four, etc., which can be determined according to the actual number of to-be-pressed regions required in the to-be-pressed piece 11, wherein each pressing assembly corresponds to a to-be-pressed region of the to-be-pressed piece 11.

[0047] In some embodiments, under the same driving of the driving assembly 12: the first pressing assembly 13a and the second pressing assembly 13b are configured to apply pressure to different regions of the to-be-pressed piece 11.

[0048] In the present embodiment, by using the same driving assembly 12, multiple pressing assemblies can be driven to press different regions of the to-be-pressed piece 11, that is, one operation can realize pressing multiple regions of the to-be-pressed piece 11, so compared with the scheme of performing multiple operations respectively to press different regions of the to-be-pressed piece 11, the number of operations is reduced, thus saving time and effort, and due to the reduction of the number of operations, the number of repeated positioning is reduced, the deviation of positioning in the pressing process is reduced, the failure in the pressing process is reduced, and thus the product production yield can be improved.

[0049] In some embodiments, the first pressing assembly 13a can include a first force transmission component 130a and a first pressing part 131a, the first pressing part 131a being connected with the driving assembly 12 through the first force transmission component 130a, the first force transmission component 130a being configured to apply a first target pressure to the first pressing part 131a under the driving of the driving assembly 12, the first pressing part 131a being configured to transmit the first target pressure to the piece to be pressed. The second pressing assembly 13b can include a second force transmission component 130b and a second pressing part 131b, the second pressing part 131b being connected with the driving assembly 12 through the second force transmission component 130b, the second force transmission component 130b being configured to apply a second target pressure to the second pressing part 131b under the driving of the driving assembly 12, the second pressing part 131b being configured to transmit the second target pressure to the piece to be pressed.

[0050] For example, during the pressing process, the driving assembly 12 can drive the first pressing assembly 13a and the second pressing assembly 13b as a whole to move towards the base 10, so that the first pressing part 131a and the second pressing part 131b are respectively in contact with different regions of the piece to be pressed.

[0051] It should be noted that after the first pressing part 131a is in contact with the piece to be pressed, if the driving assembly 12 continues to drive, the first force transmission component 130a will apply pressure to the first pressing part 131a under the driving of the driving assembly 12, and the first pressing part 131a will transmit the pressure it receives to the piece to be pressed, thereby achieving pressing. After the second pressing part 131b is in contact with the piece to be pressed, if the driving assembly 12 continues to drive, the second force transmission component 130b will apply pressure to the second pressing part 131b under the driving of the driving assembly 12, and the second pressing part 131b will transmit the pressure it receives to the piece to be pressed, thereby achieving pressing.

[0052] In some embodiments, during the pressing process, the first pressing part 131a and the second pressing part 131b can be directly connected with the piece to be pressed. Direct connection can be understood as that there is no other structure between the pressing part and the piece to be pressed, and the two are in direct contact. However, the first pressing part 131a and the second pressing part 131b can also be indirectly connected with the piece to be pressed. Indirect connection can be understood as that the pressing part can also be indirectly connected with the piece to be pressed through a pre-pressing part or other structure. Alternatively, one of the first pressing part 131a and the second pressing part 131b can be directly connected with the piece to be pressed, and the other can be indirectly connected with the piece to be pressed.

[0053] In some embodiments, with reference to Figures 1 to 4As shown, the driving assembly 12 can include a pushing element 120 and a driving element 121, the pushing element 120 is located on the side of the first and second pressing parts 131a and 131b away from the base 10 and is connected with the driving element 121.

[0054] For example, the driving element 121 and the pushing element 120 can be threadedly connected through a fastener such as a screw.

[0055] In some embodiments, the first force transmission component 130a can include a first elastic element 1301a connected between the first pressing part 131a and the pushing element 120; and the second force transmission component 130b can include a second elastic element 1301b connected between the second pressing part 131b and the pushing element 120. Wherein, the pushing element 120 is configured to perform a pressing stroke in the direction close to the first and second pressing parts 131a and 131b under the driving of the driving element 121, so as to press the first and second elastic elements 1301a and 1301b, the first elastic element 1301a will apply a rebound force to the first pressing part 131a during the pressing process, and the first pressing part 131a will apply the rebound force to the to-be-crimped member 11, the second elastic element 1301b will apply a rebound force to the second pressing part 131b during the pressing process, and the second pressing part 131b will apply the rebound force to the to-be-crimped member 11 to complete the crimping process.

[0056] It should be noted that the pressing stroke mentioned in the present embodiment is the stroke after the pressing part is in contact with the to-be-crimped member 11, that is, after the pressing part is in contact with the to-be-crimped member 11: the driving element 121 can continue to drive the pushing element 120 to move in the direction close to the base 10, since the pressing part has been in contact with the to-be-crimped member, the position of the pressing part relative to the base 10 is basically unchanged, at this time, since the pushing element 120 and the pressing part are connected through the elastic element, the pushing element 120 can continue to move relatively in the direction close to the pressing part under the driving of the driving element 121, in this case, the elastic element is in a compressed state.

[0057] In the present embodiment, the elastic element is used as the main part of the pressing assembly to apply elastic force to the to-be-crimped member 11, and the elastic force pressing can provide uniform distributed pressure on the to-be-crimped member 11, ensuring the crimping effect, in addition, the elastic force pressing can also reduce the damage to the to-be-crimped member 11 during the crimping process.

[0058] In some embodiments, the first and second pressing assemblies 13a and 13b can apply the same target pressure to the to-be-crimped member 11, or can apply different target pressures to the to-be-crimped member 11, which can be adjusted according to actual conditions.

[0059] In some embodiments, the first force transmission component 130a can be different from the second force transmission component 130b. In this way, only the pressing part needs to be replaced or adjusted according to the actual pressing requirements of the workpiece 11, and the entire pressing assembly does not need to be replaced, thereby reducing the adjustment cost of the pressing device while ensuring the universality of the pressing device.

[0060] For example, the first elastic member 1301a and the second elastic member 1301b can be designed differently.

[0061] For example, the first elastic member 1301a and the second elastic member 1301b can be designed differently.

[0062] In some embodiments, the first pressing part 131a has a first pressing surface 1310a on the side away from the pushing element 120, and the second pressing part 131b has a second pressing surface 1310b on the side away from the pushing element 120. During the pressing process, the first pressing surface 1310a can be in contact with the workpiece 11 to apply pressure to the workpiece 11, and the second pressing surface 1310b can be in contact with the workpiece 11 to apply pressure to the workpiece 11.

[0063] In some embodiments, the first pressing surface 1310a is configured to apply pressure to the workpiece 11 before the second pressing surface 1310b when the pushing element 120 performs a pressing stroke.

[0064] For example, in the working process, the driving element 121 can drive the pushing element 120 to move towards the base 10, so as to drive the first pressing assembly 13a and the second pressing assembly 13b to move towards the base 10; when the first pressing surface 1310a just contacts the to-be-pressed part 11, the second pressing surface 1310b is still spaced apart from the to-be-pressed part 11, in this case, the driving element 121 continues to drive the pushing element 120 to move towards the base 10, because the first pressing surface 1310a contacts the to-be-pressed part 11, the first pressing surface 1310a is basically stationary or has a small displacement amount relative to the to-be-pressed part 11, but the pushing element 120 still moves relative to the first pressing part 131a under the driving of the driving element 121, at this time, the first elastic element 1301a is in a compressed state; when the second pressing surface 1310b just contacts the to-be-pressed part 11, the first elastic element 1301a is in a compressed state, and the elastic force generated by the first elastic element 1301a can be applied to the to-be-pressed part 11 through the first pressing part 131a; then, the driving element 121 continues to drive the pushing element 120 to move towards the base 10, because the second pressing surface 1310b contacts the to-be-pressed part 11, the second pressing surface 1310b is basically stationary or has a small displacement amount relative to the to-be-pressed part 11, but the pushing element 120 still moves relative to the second pressing part 131b under the driving of the driving element 121, so that the second elastic element 1301b is in a compressed state, and the elastic force generated by the second elastic element 1301b can be applied to the to-be-pressed part 11 through the second pressing part 131b, at this time, the first elastic element 1301a is in a further compressed state.

[0065] In some embodiments, the first pressing surface 1310a can directly contact the to-be-pressed part 11.

[0066] In other embodiments, the first pressing surface 1310a can indirectly contact the to-be-pressed part 11.

[0067] For example, when the first pressing surface 1310a indirectly contacts the to-be-pressed part 11, as shown in FIGS. 1A and 1B, the pressing device can further include a pre-pressing part 16. Figures 1 to 4 and Figure 6 As shown in FIGS. 1A and 1B, the pressing device can further include a pre-pressing part 16.

[0068] The pre-pressing member 16 is configured to pre-press the to-be-pressed member 11 on the base 10 after the to-be-pressed member 11 is placed on the base 10 and before the pressing mechanism performs the pressing stroke, and the pre-pressing member 16 is opposite to the first pressing surface 1310a. The first pressing surface 1310a is configured to apply pressure to the first to-be-pressed area of the to-be-pressed member 11 through the pre-pressing member 16 when the pushing element 120 performs the pressing stroke, that is, the first pressing surface 1310a indirectly contacts the to-be-pressed member 11 through the pre-pressing member 16. The second pressing surface 1310b is configured to apply pressure to the second to-be-pressed area of the to-be-pressed member 11 after the first pressing surface 1310a applies pressure to the first to-be-pressed area through the pre-pressing member 16 and when the pushing element 120 continues to perform the pressing stroke.

[0069] In the embodiment, the pre-pressing member 16 is separately arranged, and the to-be-pressed member 11 is pre-pressed by the pre-pressing member 16 first. In this way, the pressing effect is ensured, and the pre-pressing member 16 meeting the requirements can be replaced according to the shape of the to-be-pressed member 11, so that the entire pressing mechanism does not need to be replaced, the cost is reduced, and the versatility of the pressing equipment is improved.

[0070] For example, in the process of pressing the to-be-pressed part 11 using the pressing device: the to-be-pressed part 11 can be placed on the base 10 first; then, the pre-pressing part 16 is placed on the base 10 in position to pre-press the to-be-pressed part 11 on the base 19, specifically, the first to-be-pressed area of the to-be-pressed part 11 is pre-pressed on the base 19 by the pre-pressing part 16; then, the driving element 121 is used to drive the pushing element 120 to move towards the base 10 to drive the first pressing assembly 13a and the second pressing assembly 13b to move towards the base 10; at this time, the first pressing surface 1310a has just contacted the pre-pressing part 16, and the second pressing surface 1310b is still spaced apart from the to-be-pressed part 11, in this case, the driving element 121 is used to continue to drive the pushing element 120 to move towards the base 10, and since the first pressing surface 1310a has contacted the pre-pressing part 16, the first pressing surface 1310a is basically stationary or has a small displacement amount relative to the pre-pressing part 16; but the pushing element 120 will still move relatively towards the first pressing part 131a under the driving of the driving element 121, at this time, the first elastic element 1301a is in a compressed state; when the second pressing surface 1310b just contacts the to-be-pressed part 11, the first elastic element 1301a is in a compressed state, and the elastic force generated by the first elastic element 1301a can be applied to the to-be-pressed part 11 through the first pressing part 131a; then, the driving element 121 is used to continue to drive the pushing element 120 to move towards the base 10, and since the second pressing surface 1310b has contacted the to-be-pressed part 11, the second pressing surface 1310b is basically stationary or has a small displacement amount relative to the to-be-pressed part 11, but the pushing element 120 will still move relatively towards the second pressing part 131b under the driving of the driving element 121, so that the second elastic element 1301b is in a compressed state, and the elastic force generated by the second elastic element 1301b can be applied to the to-be-pressed part 11 through the second pressing part 131b, at this time, the first elastic element 1301a is in a further compressed state.

[0071] In some embodiments, the first pressing surface 1310a is configured to completely cover the pre-pressing part 16 during the pressing stroke of the pressing mechanism, so that the first pressing surface 1310a can uniformly transmit the pressing force to the pre-pressing part 16 during the pressing process, so that the pre-pressing part 16 can uniformly transmit the pressing force to the first to-be-pressed area of the to-be-pressed part 11, to ensure the pressing effect.

[0072] In some embodiments, the first force transmission component 130a can further include a first fastener 1302a, one end of the first fastener 1302a can pass through the pushing element 120 and be connected with the first pressing part 131a, and the first elastic element 1301a is sleeved on the first fastener 1302a.

[0073] For example, the first fastener 1302a can be a bolt, one end of the bolt sequentially passes through the pushing element 120 and is connected with the first pressing part 131a, and the first elastic element 1301a can be a spring element, which can be sleeved on the bolt, that is, the first force transmission component 130a can be a first spring bolt.

[0074] In some embodiments, the second force transmission component 130b can further include a second fastener 1302b, one end of the second fastener 1302b can pass through the pushing element 120 and be connected with the connecting part 17, and the second elastic element 1301b is sleeved on the first fastener 1302b.

[0075] For example, the second fastener 1302b can be a bolt, one end of the bolt sequentially passes through the pushing element 120 and is connected with the connecting part 17, and the second elastic element 1301b can be a spring element, which can be sleeved on the bolt, that is, the second force transmission component 130b can be a first spring bolt.

[0076] Wherein, the pushing element is configured to slide along the first fastener 1302a and the second fastener 1302b towards the direction of approaching or away from the first pressing part 131a and the second pressing part 131b under the driving of the driving element.

[0077] In some embodiments, the value of the first target pressure is set by setting the stroke of the driving element 121 and the spring compression amount of the first spring bolt.

[0078] In some embodiments, the number of the first spring bolts can be set to be multiple, and be equal-height bolts. For example, the number of the first spring bolts can be four, as shown in FIG. Figure 1 The four first spring bolts are respectively arranged at four corner positions of the pushing element 120 and the first pressing part 131a, so that uniform distributed pressure can be provided on the to-be-pressed part 11 while ensuring the stability of the connection between the pushing element 120 and the first pressing part 131a, and the pressing effect is ensured.

[0079] It should be understood that the number of the first spring bolts is not limited to four, and can also be two, three, five, six, etc., depending on the specific circumstances, as long as uniform distributed pressure can be provided on the to-be-pressed part 11.

[0080] In some embodiments, the value of the second target pressure is set by setting the stroke of the driving element 121 and the spring compression amount of the second spring bolt.

[0081] In some embodiments, the number of the second spring bolts can be set to be multiple, and be equal-height bolts. For example, the number of the second spring bolts can be set to be Figure 5The four second spring bolts are arranged at the middle region of the pushing element 120 and at the four corners of the connecting part 17, so that the pushing element 120 and the connecting part 17 are stably connected, and uniform pressure can be provided on the to-be-crimped member 11, and the crimping effect is ensured.

[0082] It should be understood that the number of first spring bolts is not limited to four, and can be two, three, five, six, etc., depending on the specific circumstances, as long as uniform pressure can be provided on the to-be-crimped member 11.

[0083] In some embodiments, before the crimping device performs the crimping work, the pressure sensor can be used to test the crimping pressure of each pressing assembly 13 in the crimping device, so as to reduce the situation that the to-be-crimped member 11 is damaged due to excessive pressure, and to alleviate the situation that the crimping effect of the to-be-crimped member 11 is poor due to insufficient pressure.

[0084] In some embodiments, under the same driving of the driving assembly 12, the first elastic member 1301a can apply a first target pressure to the first pressing part 131a, and the second elastic member 1301b can apply a second target pressure to the second pressing part 131b.

[0085] In some embodiments, when the pressure applied by the second elastic member 1301b to the second pressing part 131b reaches the second target pressure, the pressure applied by the first elastic member 1301a to the first pressing part 131a can reach the first target pressure, that is, the first pressing assembly 13a and the second pressing assembly 13b can synchronously complete the application of corresponding target pressures to the to-be-crimped member 11, so that the crimping effect of the to-be-crimped member 11 is ensured, and the situation that part of the to-be-crimped member 11 is damaged due to excessive pressure is reduced.

[0086] In some embodiments, the first elastic member 1301a can be in a maximum compressed state when reaching the first target pressure, and the second elastic member 1301b can be in a maximum compressed state when reaching the second target pressure, so that even if the driving element 121 is used to drive the pushing element 120 to move in the direction of the base 10, the first elastic member 1301a and the second elastic member 1301b will not be compressed again, that is, the pushing element 120 has moved to the limit position, so that it is convenient to judge whether the pressures applied by the first pressing assembly 13a and the second pressing assembly 13b reach the required target value.

[0087] It should be noted that the first target pressure and the second target pressure can be the same or different, and can be set according to the actual crimping requirements of the to-be-crimped member 11.

[0088] In some implementations, the first clamping part 131a has a first mounting surface 1311a on the side near the pushing element 120, and the first mounting surface 1311a is connected to the first elastic member 1301a. The second clamping part 131b has a second mounting surface 1311b on the side near the pushing element 120, and the second mounting surface 1311b is connected to the second elastic member 1301b.

[0089] Since the first pressing surface 1310a is configured to apply pressure to the workpiece 11 to be pressed before the second pressing surface 1310b during the pressing stroke of the pushing element 120, the first elastic element 1301a and the second elastic element 1301b are compressed first. In order to ensure that the first elastic element 1301a and the second elastic element 1301b can smoothly apply the target pressure to the workpiece 11 to be pressed during the pressing stroke, the first mounting surface 1311a can be set further away from the pushing element 120 than the second mounting surface 1311b. In other words, the free length of the first elastic element 1301a can be longer than the free length of the second elastic element 1301b, so that the two can be compressed to apply elastic force.

[0090] In some embodiments, the first elastic member 1301a has a first compression amount corresponding to the first target pressure when the pushing element 120 performs the pressing stroke; the second elastic member 1301b has a second compression amount corresponding to the second target pressure when the pushing element 120 performs the pressing stroke.

[0091] It should be noted that the second compression amount can be different from or the same as the first compression amount, depending on the actual situation.

[0092] For example, when the elastic coefficients of the first elastic element 1301a and the second elastic element 1301b are the same, and the first target pressure and the second target pressure actually required by the component to be pressed 11 are different, the first compression amount and the second compression amount may be different. When the elastic coefficients of the first elastic element 1301a and the second elastic element 1301b are the same, and the first target pressure and the second target pressure actually required by the component to be pressed 11 are the same, the first compression amount and the second compression amount may be the same.

[0093] In some embodiments, reference Figure 4 and Figure 9 As shown, the first pressing part 131a has a through hole 1312, the pre-pressing part 16 has a through hole 162, and the second pressing part 131b is configured to apply pressure to the part to be pressed 11 through the through hole 1312 and the through hole 162. Such a pressing device is adapted to the part to be pressed 11 in which the two pressing areas are arranged in a ring.

[0094] It should be noted that the first pressing part 131a and the second pressing part 131b are not limited to Figures 1 to 4The sleeve relationship shown can also be arranged side by side, and the like, and can be determined according to the arrangement relationship of the to-be-pressed part 11.

[0095] In some embodiments, the second pressing part 131b is in clearance fit with the inner hole wall of the through hole 162 and the through hole 1312, so that the second pressing part 131b is not easy to jam during pressing, and can smoothly pass through the first pressing part 131a and the pre-pressing part 16.

[0096] For example, the gap between the second pressing part 131b and the through hole 1312 can be about 0.3 mm, which can ensure that the second pressing part 131b can smoothly pass through the through hole 1312, and can also reduce the risk of foreign matter falling into the gap between them.

[0097] In some embodiments, referring to Figures 1 to 4 As shown, the pressing device can include a base 14 and a mounting bracket 15 arranged on the base 14, and the base 10 is arranged on the base 14.

[0098] For example, the base 14 and the mounting bracket 15 can be connected together by pin positioning and bolt fixing, but are not limited thereto, and can also be fixed by magnetic attraction, depending on the specific circumstances.

[0099] In some embodiments, referring to Figure 2 As shown, the fixed end of the driving element 121 can be connected with the mounting bracket 15, the action end of the driving element 121 is connected with the pushing element 120, the mounting bracket 15 is provided with a guide rail 150 and first and second sliding blocks 151a and 151b slidingly arranged in the guide rail 150, the extension direction of the guide rail 150 can be the same as the driving direction of the driving element 121, the first pressing part 131a is connected with the first sliding block 151a, and the second pressing part 131b is connected with the second transmission component 130b through a connecting part 17, and the connecting part 17 is connected with the second sliding block 151b. This design can ensure the accuracy of the movement track of the first pressing assembly 13a and the second pressing assembly 13b during pressing, and ensure the pressing yield.

[0100] For example, the second pressing part 131b and the connecting part 17 can be connected together by screws or bolts and the like.

[0101] For example, the connection between the first pressing part 131a and the first sliding block 151a, and the connection between the connecting part 17 and the second sliding block 151b can be fixed by screws or bolts and the like.

[0102] In some embodiments, the drive element 121 may include a quick clamp and a linear bearing. The quick clamp is characterized by its small size, ease of operation, low cost, and manual pressure application. Specifically, by manually applying pressure to the quick clamp, the slider 151 is driven to slide along the guide rail 150 under the guidance of the linear bearing.

[0103] In some other embodiments, the quick clamp in the drive element 121 may be replaced with a cylinder to achieve pneumatic drive.

[0104] In some embodiments, reference Figures 1 to 4 As shown, the base 14 may be provided with a positioning groove 140, the base 10 is installed in the positioning groove 140, and the outer side of the base 10 is connected to the side wall of the positioning groove 140 to play a positioning role.

[0105] For example, the base 14 and the base 10 can be connected together by means of pin positioning and bolt fixing; but not limited to this, the base 14 and the base 10 can also be fixed by means of magnetic attraction.

[0106] In some embodiments, the component to be pressed 11 may be an earphone vibrator, which may include a vibration component and a magnetic component. The vibration component may include a diaphragm, a coil, a diaphragm support, and a pad (not shown) fixed on the diaphragm support.

[0107] In the process of assembling headphones, the vibration components need to be assembled with adhesive, and then the diaphragm, diaphragm support and coil are pressed together using a pressing device until the adhesive solidifies, thereby obtaining a reliable vibration component.

[0108] In some embodiments, reference Figure 7 As shown, the diaphragm may include a main body region 180 and a folded ring region 181 that surrounds the main body region 180 and protrudes from the periphery. The main body region 180 includes an inner body 1801 and an outer body edge 1802 surrounding the inner body 1801. The folded ring region 181 includes an inner folded ring edge 1810 surrounding the outer body edge 1802, a folded ring flange 1811 surrounding the inner folded ring edge 1810, and an outer folded ring edge 1812 surrounding the folded ring flange 1811.

[0109] The dispensing process is as follows: the outer edge 1802 of the main body is bonded to the coil, and the outer edge 1812 of the folded ring is bonded to the diaphragm support. In other words, the areas that need to be pressed by the pressing equipment may include a first pressing area and a second pressing area. The first pressing area is the area where the outer edge 1812 of the folded ring is connected to the diaphragm support, and the second pressing area is the area where the outer edge 1802 of the main body is connected to the coil. The first pressing area surrounds the second pressing area.

[0110] The pressing process is as follows: after the glue is applied, the pressing equipment presses the first and second areas to be pressed until the glue is solidified, so that a reliable vibration assembly is obtained.

[0111] In some embodiments, the first pressing assembly 13a of the pressing equipment can be configured to press the first area to be pressed, and the second pressing assembly 13b can be configured to press the second area to be pressed.

[0112] In some embodiments, under the same driving of the driving assembly 12, the first pressing assembly 13a can apply a first target pressure to the first area to be pressed, and the second pressing assembly 13b can apply a second target pressure to the second area to be pressed. In this embodiment, the first and second areas to be pressed can be pressed in one operation, which is more time-saving and labor-saving than pressing the first and second areas to be pressed twice respectively, and is less likely to make mistakes.

[0113] In some embodiments, in the initial state: the pre-pressing piece 16 is pressed on the first area to be pressed, and a gap of a certain height can be provided between the contact surface 1624 of the pre-pressing piece 16 and the groove bottom surface of the first groove body 1010 of the base 10, so as to transmit the target pressure to the pre-pressing piece 16 through the first pressing surface 1310a when the first pressing part 131a is pressed down, and then to the folded ring outer edge 1812 of the diaphragm through the pre-pressing piece 16, which facilitates the transmission of pressure in the subsequent pressing process. The gap between the contact surface 1624 of the pre-pressing piece 16 and the groove bottom surface of the first groove body 1010 of the base 10 can be set according to the stacking assembly tolerance of the diaphragm assembly (such as the thickness tolerance of the diaphragm assembly).

[0114] In some embodiments, in the initial state: a gap of a certain height can be provided between the pressing surface 1310 of the second pressing part 131b and the second area to be pressed, so as to transmit the target pressure to the main body outer edge 1802 of the diaphragm through the pressing surface 1310 of the second pressing part 131b when the second pressing part 131b is pressed down, which facilitates the transmission of pressure in the subsequent pressing process.

[0115] In some embodiments, in the initial state: a gap of a certain height can be provided between the pressing surface 1310 of the second pressing part 131b and the second area to be pressed, so as to transmit the target pressure to the main body outer edge 1802 of the diaphragm through the pressing surface 1310 of the second pressing part 131b when the second pressing part 131b is pressed down, which facilitates the transmission of pressure in the subsequent pressing process.

[0116] For example, the pressing surface 1310 of the second pressing part 131b can be provided as a flat surface, so that when it contacts the main body region 180 of the diaphragm, the pressure is uniformly applied, thereby improving the situation that the diaphragm is damaged due to uneven stress.

[0117] For example, since the second to-be-bonding area is the area where the outer edge 1802 of the main body of the diaphragm is connected to the coil, the size of the bonding surface 1310 of the second pressing part 131b is designed according to the size of the coil.

[0118] For example, the first pressing part 131a and the second pressing part 131b can be plastic or rubber parts, which are not easy to scratch the diaphragm, and when the force is too large, the pressing part 131 of the plastic / rubber part has a certain elasticity and is not easy to directly damage the diaphragm.

[0119] In some embodiments, since the diaphragm is easy to be damaged, the bonding equipment needs to be debugged to different target pressures before performing the bonding work to meet the bonding requirements of the diaphragm, so the bonding pressure of the diaphragm area should be adjustable.

[0120] For example, the required bonding pressure of the folded ring outer edge 1812 of the diaphragm can be 10 to 15 N, that is, the first target pressure can be 10 to 15 N, such as 10 N, 11 N, 12 N, 13 N, 14 N, 15 N, etc., depending on the specific circumstances.

[0121] For example, the required bonding pressure of the folded ring outer edge 1812 of the diaphragm can be 2 to 4 N, that is, the second target pressure can be 2 to 4 N, such as 2 N, 3 N, 4 N, etc., depending on the specific circumstances.

[0122] In some embodiments, the folded ring area 181 of the diaphragm has a small area and a curved surface structure, so in order to adapt to the diaphragm, the through hole 162 of the pre-pressing part can use a stepped structure to match the shape of the folded ring.

[0123] For example, in the bonding process, in order to protect the folded ring flange 1811 from being bonded, the through hole 162 of the pre-pressing part 16 can be arranged in a stepped manner to have a gap that avoids the folded ring flange 1811, that is, when the pre-pressing part 16 applies the first target pressure to the first to-be-bonding area and the second pressing part 131b applies the second target pressure to the second to-be-bonding area, the stepped surface opposite to the folded ring flange 1811 in the through hole 162 has a gap with the folded ring flange 1811.

[0124] In some embodiments, in combination with the Figure 8 and Figure 9 As shown, the through hole 162 of the pre-pressing part 16 can include a first hole segment 1620, a second hole segment 1621, a third hole segment 1622, and a fourth hole segment 1623 arranged in sequence in a direction away from the base 10, and the hole diameters of the first hole segment 1620, the second hole segment 1621, the third hole segment 1622, and the fourth hole segment 1623 decrease in sequence.

[0125] Among them, refer to Figure 6 and Figure 9As shown, the end surface of the first hole section 1620 away from the second hole section 1621 is configured as a contact surface 1624 in contact with the base 10; a press-fit step surface 1627 is formed between the first hole section 1620 and the second hole section 1621; a first step surface 1625 is formed between the second hole section 1621 and the third hole section 1622, and the first step surface 1625 is configured to avoid the folded ring flange 1811 of the vibrator when the press-fit step surface 1627 is in contact with the to-be-pressed part 11; a second step surface 1626 is formed between the third hole section 1622 and the fourth hole section 1623, and the second step surface 1626 is configured to form a gap between the second pressing part 131b and the inner hole surface of the third hole section 1622, so that the second pressing part 131b can be pressed without being stuck and can be smoothly moved up and down.

[0126] In some embodiments, the second pressing part 131b and the inner hole surface of the fourth hole section 1623 can also be gap-fitted, so that the second pressing part 131b can be pressed without being stuck and can be smoothly moved up and down.

[0127] In some embodiments, referring to Figure 10 As shown, the base 10 can be provided with a stepped placement groove 101, which has a first groove body 1010 and a second groove body 1011 formed on the groove bottom of the first groove body 1010, and the second groove body 1011 is provided with a positioning protrusion 102; the groove bottom surface of the first groove body 1010 is configured to be opposite to the contact surface 1624 of the first hole section 1620 away from the second hole section 1621. The second groove body 1011 is configured to accommodate the coil, and the positioning protrusion 102 is configured to be sleeved by the coil.

[0128] In the initial state: after the to-be-pressed part 11 is placed in the stepped placement groove 101, the first to-be-pressed area can be overlapped on the groove bottom surface of the first groove body 1010, and then the pre-pressing part 16 is pre-pressed on the first to-be-pressed area, at this time, the press-fit step surface 1627 of the pre-pressing part 16 is in contact with the first to-be-pressed area, and a gap is left between the contact surface 1624 of the pre-pressing part 16 and the groove bottom surface of the first groove body 1010. After the subsequent pressing process, the contact surface 1624 of the pre-pressing part 16 is in contact with the groove bottom surface of the first groove body 1010 to press the first to-be-pressed area.

[0129] For example, the outer hole surface of the first hole section 1620 can be in contact with the groove side surface of the first groove body 1010, so that the position of the pre-pressing part 16 can be limited by the first groove body 1010 to achieve aligned pressing, thereby improving the pressing effect.

[0130] In some embodiments, in order to adapt to the feature that the side wall of the diaphragm assembly has a curved surface structure, the wall surface of the base 10 in contact with the side wall of the diaphragm assembly can be designed as a profiling structure consistent with the side wall of the diaphragm assembly.

[0131] In some embodiments, referring to Figure 10 As shown in FIG. 10, the base 10 is further provided with at least one group of lead slot groups 103, each of which includes first lead slots 1031 and second lead slots 1032 arranged at intervals, and one end of each of the first lead slots 1031 and the second lead slots 1032 extends to the first slot body 1010 and the second slot body 1011, and the other end of each of the first lead slots 1031 and the second lead slots 1032 extends to the side of the base 10, and the first lead slots 1031 are configured to lead out the first end of the coil, and the second lead slots 1032 are configured to lead out the second end of the coil.

[0132] In the present embodiment, by arranging the first lead slots 1031 and the second lead slots 1032, the two ends of the coil can be led out, and the situation that the leading-out section of the coil is broken during the pressing process can be reduced.

[0133] For example, referring to Figure 10 As shown in FIG. 11, the base 10 can be provided with two groups of lead slot groups 103, and the two groups of lead slot groups 103 can be symmetrically arranged about the stepped placement slot 101, so that the limitation on the placement of the vibration assembly during the placement process can be reduced.

[0134] In some embodiments, the base 10 can have a placement area and a peripheral area located outside the placement area, and the placement area is configured to place the vibration assembly.

[0135] For example, referring to Figure 10 As shown in FIG. 12, the peripheral area of the base 10 can be provided with a first positioning part 104, and the pre-pressing part 16 is provided with a second positioning part 1612 opposite to the first positioning part 104, and the first positioning part 104 and the second positioning part 1612 are configured to be positioned and matched during the pressing process, so that the pressing alignment accuracy can be ensured, and thus the pressing effect can be ensured.

[0136] For example, one of the first positioning part 104 and the second positioning part 1612 can be a protrusion, and the other can be a groove for inserting the protrusion.

[0137] For example, the first positioning part 104 and the second positioning part 1612 can be pin holes, and the positioning and matching between the base 10 and the pre-pressing part 16 can be achieved by cooperating with the pins.

[0138] In some embodiments, the outer periphery of the base 10 may be provided with a first magnet (not shown in the figure), and the pre-pressing member 16 is provided with a second magnet (not shown in the figure) that is opposite to the first magnet and has opposite magnetic properties. The first magnet and the second magnet are configured to attract each other magnetically during the pressing process. This can fix the positional relationship between the base 10 and the pre-pressing member 16 during the pressing process. On the one hand, it can prevent the pre-pressing member 16 from deviating from the base 10, thereby ensuring the accuracy of the pressing alignment. On the other hand, it can also ensure the pressing force between the pre-pressing member 16 and the base 10, ensuring the pressing effect.

[0139] For example, refer to Figure 10 As shown, the outer periphery of the base 10 may be provided with a first magnetic step hole 105. The diameter of each hole segment in the first magnetic step hole 105 decreases sequentially from the direction away from the pre-compression member 16. The first magnet can be limited by the stepped surface in the hole segment of the first magnetic step hole 105 close to the pre-compression member 16.

[0140] The first magnetic step hole 105 can penetrate the base 10, which makes it convenient to push the first magnet out of the first magnetic step hole 105 from the side of the base 10 away from the pre-compression member 16.

[0141] For example, refer to Figure 8 As shown, the pre-compression member 16 may be provided with a second magnetic stepped hole 1613. The diameter of each hole segment in the second magnetic stepped hole 1613 decreases sequentially from the direction away from the base 10. The second magnet can be limited by the stepped surface in the hole segment of the second magnetic stepped hole 1613 near the base 10.

[0142] The second magnetic step hole 1613 can penetrate the pre-compression member 16, which makes it convenient to push the second magnet out of the second magnetic step hole 1613 from the side of the pre-compression member 16 away from the base 10.

[0143] In some embodiments, the placement area of ​​the base 10 may be provided with a third magnet (not shown in the figure), and the pre-pressing member 16 may be provided with a fourth magnet (not shown in the figure) that is opposite to the third magnet and has opposite magnetic properties. The third magnet and the fourth magnet are configured to attract each other magnetically during the pressing process. This can fix the vibration component between the pre-pressing member 16 and the base 10, and can prevent the vibration component from deviating from the base 10 and the pre-pressing member 16, thereby ensuring the accuracy of the pressing alignment.

[0144] For example, refer to Figure 10 As shown, the placement area of ​​the base 10 may be provided with a third magnetic step hole 106. The diameter of each hole segment in the third magnetic step hole 106 decreases sequentially from the direction away from the pre-compression member 16. The third magnet can be limited by the step surface in the hole segment of the third magnetic step hole 106 close to the pre-compression member 16.

[0145] The third magnetic attraction stepped hole 106 can pass through the base 10, so that the third magnet can be pushed out of the third magnetic attraction stepped hole 106 from the side of the base 10 away from the pre-pressing part 16.

[0146] For example, referring to Figure 8 The pre-pressing part 16 can be provided with a fourth magnetic attraction stepped hole 1614, the hole diameter of each hole section of the fourth magnetic attraction stepped hole 1614 decreases in turn from the direction away from the base 10, and the fourth magnet can be limited in the hole section of the fourth magnetic attraction stepped hole 1614 close to the base 10 by the stepped surface.

[0147] The fourth magnetic attraction stepped hole 1614 can pass through the pre-pressing part 16, so that the fourth magnet can be pushed out of the fourth magnetic attraction stepped hole 1614 from the side of the pre-pressing part 16 away from the base 10.
