PASSIVE RADIATOR STRUCTURE

摘要

A passive radiator structure includes an integrally formed diaphragm structure and a surround suspension. The diaphragm structure includes a diaphragm, a frame, and a web-like spider having a plurality of suspension arms integrally extended to between the diaphragm and the frame. The surround suspension has a radially inner gluing edge adhered to a radially inner location of the diaphragm structure around the diaphragm, and a radially outer gluing edge adhered to a radially outer location of the diaphragm structure around the frame. The surround suspension and the web-like spider of the diaphragm structure form two suspension elements for stably supporting the diaphragm, enabling minimized irregular shaking and reduced weight of the diaphragm, as well as reduced sound distortion, increased compliance and upgraded efficiency of the passive radiator structure.

主权项

1. A passive radiator structure, comprising:
a diaphragm; a frame externally located around the diaphragm; a web-like spider having a plurality of suspension arms extending between the diaphragm and the frame and circumferentially equally spaced from one another by a predetermined distance and connecting the frame to the diaphragm, such that a single, integral diaphragm structure is integrally formed of the web-like spider, the diaphragm and the frame; and a surround suspension glued over the single, integral diaphragm structure; whereby the diaphragm is supported by both of the web-like spider and the surround suspension.
