Definitions
- the invention relates to a central or pe ⁇ phe ⁇ que suspension of the mobile assembly of an electrodynamic loudspeaker comprising a rigorous centering of the mobile parts 6,7, a reduction in the magnetic air gap 2 and a maximum clearance of the bitter from the membrane by removing the spider
- Figure 2 is an isolated view of the core of Figure 1
- Figure 3 provides an alternative placement of the suspension on the scattering warhead 1 in place of the core figure 2 but all the features are comparable
- Figures 8 and 9 are also the possibilities of location of the guides of the centering grooves 4. Items 1 1 and 12 must be reported to the loudspeaker frame, but the operation is similar.
- the material constituting the flexible element can be rubber, plastic, felt, etc.
