description of the invention, conventionally as a speaker dynamic plate, any paper-like molding,
polymer foam, polymer film, etc. as pulp. . Metal foils have been used, but they have long and
short lengths, respectively, which are sufficiently satisfactory as dynamic plates. That is, fiber 1 II
WI dynamic plates are S mechanical due to friction between fibers. It happens to the steep
greetings because there is an internal loss, but it is a ratio! It has a low modulus and is
susceptible to humidity, which has its disadvantages, and normal metal foils have a high specific
modulus of elasticity 1fr #, but they have a small loss due to their small area P , It is easy to catch
a steep greeting, and there is a defect such as non-linear operation at the time of large scale w1
and distortion I due to movement. General <egos compounds, high value i high modulus
containing high hardness to i value elastic modulus, but these tjl1 bodies are used as a multiacting plate-ゐ #: r #): always difficult. X invention d1 specific gravity is! A small titanium foil and
a large titanium foil! As a core material t) @ @ @ @ 化 物 値 debit, there is a-coexistence layer?
Disappointing-"by-"-core material OII machined mounting capacity Jl processability of oxide,
