Description

[0002] With the progress and development of science and technology, more and more media playback electronic products are developing towards multifunctionality, miniaturization, lightness and industrialization, which makes the mass production requirements of speakers higher. The core components of existing speakers include annular centering frame, voice coil sleeve and vibration cone. Therefore, it is necessary to first install the annular centering frame inside the speaker shell, and then connect the voice coil sleeve around the inner side of the annular centering frame. In this way, the vibration stability of the voice coil sleeve is ensured by the annular centering frame. Finally, it is necessary to connect the vibration cone on the outer side of the upper end of the voice coil sleeve, and then elastically fix the outer end of the vibration cone to the outer end of the speaker shell, so as to achieve a series of connections. Generally, the annular centering frame, voice coil sleeve, vibration cone, etc. are all bonded by glue, which makes the connection more complicated. If the annular centering frame, voice coil sleeve and vibration cone can be integrated in advance and then quickly assembled with the speaker shell, the production efficiency will be greatly improved.
