Speaker Ring low price and thin margin
China has become the largest producer of ring magnets in the world.
*China produced about 123,000 ton of speaker ring magnets in 2001.
China can meet almost all reasonable quality requirements of ring magnets
Price drop has never stopped at the bottom predicted from time to time.since mid 2000.
For big rings(OD over 100mm) about 30% less
For small rings even over 5% less
The effect of the thin margin
Less input into quality improvement
Less requirements on ?luxury?quality
*many applications do not really need ?high quality?/p>
*Acceptance threshold has been lowered quietly
?Chicken rib?won?t have promising future
