Abstract
The present invention discloses a glass diaphragm having a functional layer which is selected from one of the following group or the combination thereof: explosion-proof layer, decorative layer, waterproof layer, and anti-reflection layer. The anti-explosion layer is made of PU, PVB, PC, PET or PMMA, the decorative layer contains ink materials, and the anti-reflection layer includes porous or raised structures formed by nanometer materials. The functional layer is formed by coating, spraying, pasting, ink jetting, coating.
Claims14
A glass diaphragm speaker having a functional layer comprising:
- magnets;
- planar voice coils formed adjacent to said magnets and on a non-display side surface of a planar display, wherein said magnets are formed in a Halbach Array configuration to enhance a magnetic field strength per unit, wherein a glass substrate of said planar display acts as a glass diaphragm, thereby forming said planar voice coils on said glass diaphragm by printing, coating or photolithography, and said magnets being placed under said glass diaphragm to create a magnetic field, said magnetic field at a top of said magnets being relatively strong, while said magnetic field at a bottom of said magnets being relatively weak, thereby gathering magnetic field lines between said magnets and said planar voice coils;
- wherein said functional layer formed on a surface of said glass diaphragm, wherein said functional layer is selected from one or the combination thereof:
- explosion-proof layer, decorative layer, waterproof layer, and anti-reflection layer, wherein said anti-reflection layer includes nano-meter material having porous or raised structures, wherein said decorative layer includes ink.
