(4)在对发声单体20和盖板10之间的防水胶水进行的保压工作完成后，根据实际需要，在三角槽50中进行第二次打胶，防水胶水溢向间隙40以对凸墙12的朝向发声单体20的侧壁面12a与发声单体20的外壁面20a之间的间隙40进行补胶。
该方法包括了打胶压合、保压以及补胶等一系列步骤，在打胶压合的过程中，环形凹槽111、环形凹槽111的第一槽壁端部1111以及间隙40等结构的相互配合，保证了防水胶水可以足量以对盖板10和发声单体20进行稳定的胶合，也保证了防水胶水不会溢向音膜，对音膜造成污染。同时，三角槽50和间隙40连通，方便了后续的补胶工作，进一步确保盖板10和发声单体20之间胶合的稳定性。
本发明通过在第二固定部11开设环形凹槽111以容纳足量的液态防水胶水，凸墙12的靠近环形凹槽111的侧壁面12a与环形凹槽111的第二槽壁表面平行设置且平整相连，并与发声单体20的外壁面20a形成间隙40，间隙40用来收容余量的防水胶水；环形凹槽111的远离凸墙12的第一槽壁端部1111顶在第一固定部22上以防止液态防水胶水溢向音膜。在间隙40与环形凹槽111的第一槽壁端部1111配合下，既保证了发声单体20与盖板10之间的胶合力度，也确保了防水胶水不会溢向音膜。同时，三角槽50的形成使得后续的补胶工作可以快速进行。运用本技术方案，同时确保了音膜的质量以及发声单体20和盖板10之间的胶合质量。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
