From the previous post,we learned about the impact of Improper design on the quality of sound.Today,we'll learn how the same could adversely affect our Ears.
This is the back side of the Fake chinese driver:
and,this one is the back side of Sony's Driver:
Okay,things you'll notice here,both these drivers have got the black surrounding.this is nothing but the filter that filters out unwanted frequencies..this...is a crucial segment in speaker design.
If there was'nt a filter,this would allow unwanted frequencies to pass throught our ears - Contrbuting a small part to the hearing Loss.
In addition to the side filters, Sony has also added a filter in the centre,which not only limits certain frequencies,but also limits the movement of the diaphragm (cone).In case of the chinese driver,there is sticky glue present in the centre as well as the sides,which results in uneven Sound distribution.
How does this affect my Health?
Well,since the filters present in the chinese drivers are of low quality,this may allow unwanted,especially higher frequencies that may cause damage to our ears.That also explains why the chinese drivers sound "not-so-clear".
