Description

Technical Field

[0001] This utility model relates to a welding fixture suitable for moving iron unit springs. Background Technology

[0002] As an electroacoustic product, the loudspeaker is an essential sound-generating component in communication products. The balanced armature driver in headphones primarily uses two sound conduction methods: one is through compressed air, where air pressure drives the inner eardrum to the cochlea; the other is through direct vibration of the skull to the ossicles and finally to the cochlea.

[0003] Vibrating speakers, a type of bone conduction speaker with a balanced armature driver, directly convert electronic signals into mechanical signals. They are used in wearable audio devices to meet specific sound needs. They transmit sound through vibration rather than applying pressure to the surrounding air, resulting in very clear audio signal transmission. However, existing vibrating speakers use glue to bond internal parts, leading to poor mechanical stability and a tendency to deform and loosen.

[0004] A search revealed a patent: a loudspeaker with an integrated injection-molded vibrating reed and welding spring (CN202210777916.2), comprising a magnetic circuit and a vibrating part connected by rivets. The magnetic circuit includes a magnetic cup and magnets and pole plates stacked sequentially within the cup. The vibrating part includes a welding spring, a vibrating reed, a voice coil, plastic parts, and plastic. While the rivet connection provides a relatively fixed connection, its stability is still poor.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of welding fixture suitable for moving iron unit springs, so as to make it more industrially valuable. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] Example

[0026] like Figure 1 , Figure 2 and Figure 3As shown, a welding fixture suitable for moving iron unit springs includes a fixed base 1, a placement platform 2 for placing products connected to the side of the fixed base 1, a pad 3 connected to the fixed base 1, a right positioning fixing block 4 for positioning and fixing products connected to the right side of the pad 3, a sliding groove 5 on the left side of the pad 3, a left positioning fixing block 6 slidably connected in the sliding groove 5, a fixing plate 7 connected to the pad 3, and a recess 8 on the fixing plate 7 opposite to the placement platform 2, on which a positioning and fixing block 6 is connected. The product is fixed by a rear positioning block 9. A fixing base 10 is connected to the fixing base 1 located outside the placement platform. A guide groove 11 is provided in the fixing base 10. A sliding block 12 is slidably connected in the guide groove 11. A front fixing block 13 for fixing the front end of the product is connected to the sliding block 12. A locking rod 14 is passed through the fixing base 10. One end of the locking rod 14 is connected to the sliding block 12. A pressing column 15 is connected to the fixing plate 7. A pressing connecting block 16 for pressing the top of the product is connected to the pressing column 15.

[0027] The clamping connecting block 16 is movably connected to the clamping column via a connecting sliding sleeve, and the connecting sliding sleeve is fixed to the clamping column by snap-fit.

[0028] The locking rod 14 described in this utility model is screwed onto the fixed base 10.

[0029] In this utility model, the notch 8 is connected to a slot, and the rear positioning and fixing block 9 is engaged in the slot.

[0030] In this utility model, a locking block 17 is connected to the pad 3, and a left locking rod is passed through the locking block 17. The left locking rod passes through the locking block and is connected to the left positioning and fixing block 6. The left locking rod is threadedly connected to the locking block 17.

[0031] In this invention, a height-limiting block 18 is connected to the fixing plate 7 to limit the height of the connecting block 16, ensuring the spring is bent.

[0032] In this utility model, a limiting groove 19 is provided on the fixed base 1, and a limiting slide plate 20 for limiting the position of the left positioning fixing block 6 is slidably connected on the limiting groove 19. A sliding hole 21 is provided on the fixed base 1 located in the limiting groove, and a limiting push rod 22 is slidably connected in the sliding hole 21. The limiting push rod 22 is connected to the limiting slide plate 20 by a connecting bolt.

[0033] In this invention, the side of the limiting slide plate 20 that contacts the left positioning fixing block 6 is provided with an inclined structure. As the limiting slide plate moves closer to the placement platform, the limiting distance of the left positioning fixing block becomes narrower.

[0034] The working principle of this utility model is as follows:

[0035] In actual operation, the product is placed on the placement table under the positioning of the right positioning fixing block and the rear positioning fixing block. Then, the front end and left end of the product are fixed again by the locking rod and the left locking rod. When fixing the left side of the product, the limiting slide plate first moves to the designated position (that is, the corresponding position is determined according to the product size), so that the left positioning fixing block can fix the product without damaging it. Finally, the pressing connecting block presses the spring to the designated curvature and then welds the spring to the product.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0039] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
