Three part membrane speaker

摘要

A speaker assembly membrane including a sound radiating surface (SRS) having a first material; a substantially planar SRS ring positioned concentrically outward from the SRS and having a second material; and a suspension member positioned concentrically outward from the SRS ring and having a third material. The second material is stiffer than the first material and the third material to locally stiffen an area surrounding the SRS and improve a breaking mode frequency of the membrane. In another embodiment, the speaker assembly membrane may include a diaphragm having a first material density; a substantially planar stiffening ring extending radially outward from an outer edge of the diaphragm and having a second material density; and a suspension member extending radially outward from an outer edge of the stiffening ring and having a third material density. The second material density is greater than the first material density and the third material density.

1. A speaker assembly membrane comprising:
a sound radiating surface (SRS) having a first material; a planar SRS ring positioned concentrically outward from an outer edge of the SRS and having a second material; and a suspension member positioned concentrically outward from an outer edge of the SRS ring and having a third material, and wherein the second material is stiffer than the first material and the third material so as to locally stiffen an area surrounding the SRS and improve a breaking mode frequency of the membrane.
