Problems solved by technology

When assembling the sound generator, it is necessary to use glue to bond and fix the pre-wound voice coil on the diaphragm or vibration plate. At the same time, it is not easy to position when bonding the voice coil, resulting in poor concentricity of the vibrating components after bonding. , poor consistency, which in turn affects the acoustic performance of the sounder

Embodiment 1

[0036] Such as figure 1 and figure 2 Commonly shown, a voice coil winding method, a protruding annular winding boss 12 is provided on one side of the vibrating plate 10, and the voice coil wire is wound on the winding boss 12 based on the winding boss 12 At the same time, the voice coil wire is heated to melt its adhesive layer and be directly bonded to the vibration plate 10, so that the voice coil after winding can be directly combined with the vibration plate 10, which can save both The bonding process. In this embodiment, heating is carried out by blowing hot air on the voice coil wire, and hot air is blown while winding the voice coil wire, so that the voice coil can be well fixed to the vibration plate 10 .

[0037] Such as figure 1 , figure 2 , Figure 7 and Figure 8 As shown together, if the height of the winding boss 12 is greater than that of the voice coil, the voice coil wire can be directly wound on the winding boss 12 without any tooling. If the height ...

Embodiment 2

[0042] Such as image 3 As shown, a vibrating assembly includes a combined diaphragm (not shown), a vibrating plate 10 and a voice coil 20a, and a downwardly protruding ring-shaped winding boss 12 is provided below the vibrating plate 10, The voice coil 20a is wound on the outer side of the winding boss 12, and the voice coil 20a is bonded together with the outer side of the winding boss 12 and the lower side of the corresponding part of the vibrating plate 10 through the adhesive layer on the voice coil wire itself.

[0043] Such as image 3 As shown, the height of the winding boss 12 in this embodiment is smaller than the height of the voice coil 20a, and the inner surface and the outer surface of the voice coil 20a are both planar structures, that is, the inner surface of the voice coil 20a and the winding boss 12 The outside surface is flush.

[0044] Such as image 3As shown, in this embodiment, the material of the vibrating plate 10 is preferably polymer plastic or li...

Embodiment 3

[0046] Such as Figure 4 As shown, this embodiment is basically the same as Embodiment 2, the difference is:

[0047] The outer surface of the voice coil 20b is a planar structure, and the inner surface is a stepped structure with concave up and convex down. Meanwhile, the inner surface of the voice coil 20b is flush with the inner surface of the winding boss 12 .

Abstract

Disclosed are a method for winding a voice coil (20a, 20b, 20c, 20d, 20e, 20f), and a vibration assembly and a sounder with the vibration assembly. The method for winding the voice coil (20a, 20b, 20c, 20d, 20e, 20f) comprises the following steps: arranging a protruding annular winding boss (12) at one side of a vibrating plate (10); winding the voice coil around an outer side of the annular winding boss (12); heating a voice coil wire, so that an adhesive layer of the voice coil wire is melted and directly bonded on the vibrating plate (10); and the wound voice coil (20a, 20b, 20c, 20d, 20e, 20f) directly being integrated with the vibrating plate (10) as a whole. The method for winding the voice coil (20a, 20b, 20c, 20d, 20e, 20f), and the vibration assembly and the sounder with the vibration assembly solve the technical problems in the prior art, such as the complicated assembly process of a sounder. The method for winding the voice coil (20a, 20b, 20c, 20d, 20e, 20f), and the vibration assembly and the sounder with the vibration assembly have a simple process of assembly and a high assembly efficiency, and the products thereof have a high concentricity, a good consistency, and a high acoustic performance.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a voice coil winding method, a vibrating component and a sound generator provided with the vibrating component. Background technique [0002] The sound generator is an important acoustic component of portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The sound generator usually includes a casing, a vibration component and a magnetic circuit component accommodated in the casing, and the vibration component usually includes a diaphragm, a vibration plate and a voice coil. At present, the voice coils are all made of voice coil wires, and the commonly used voice coil wires are enameled wires with a glue layer. When assembling the sound generator, it is necessary to use glue to bond and fix the pre-wound voice coil on the diaphragm or vibration plate. At the same ti...
