Abstract
The invention discloses a kind of passive radiant panel and preparation method thereof, passive radiant panel is made using the combination of the constant weight percentage of the dimethyl methyl ethylene (siloxanes and polysiloxanes) of ethenyl blocking, dimethyldimethoxysil,ne, Silica hydrogel and hydroxy-end capped dimethyl (siloxanes and polysiloxanes) in the passive radiant panel, and the present invention can solve the problems, such as that speaker bass effect is performed poor in the prior art.
Description
Technical field
The present invention is on speaker field, more particularly to a kind of passive radiant panel for speaker and preparation method thereof.
Background technology
For small speaker or mini speaker, due to the limitation of volume, the loudspeaker used can not possibly be too big, generally all makes
With 2 inches or less than 2 inches of loudspeaker, consequently, it is possible to since the bore of Loudspeaker diaphragm is too small, when it is vibrated every time, promotion
Air capacity is with regard to seldom, and the volume of air that amount of bass sense is promoted with loudspeaker has direct relation, and like this, the born of mini speaker lacks
Fall into the shortage for having led to its bass.
And passive radiant panel (also referred to as passive radiation film, passive vibrating diaphragm), then it can preferably solve the problems, such as this, it is real
On border, the structure of passive vibrating diaphragm and loudspeaker similarity in a measure, have the vibrating diaphragm for promoting air and allow vibrating diaphragm to recover normal position
Put required ring, but unlike, it is no driving mechanism in passive vibrating diaphragm, that is to say, that its own can not be sent out
Go out sound, then, how passive vibrating diaphragm worksSince passive vibrating diaphragm and loudspeaker unit are mounted in the babinet of sealing,
In this way, when loudspeaker work makes a sound, the movement of loudspeaker unit, can cause the air in babinet to be compressed and extended, in gas
Under the action of buckling, passive vibrating diaphragm produces vibration, promotes the air outside babinet, can thus make a sound and.Due to quilt
Dynamic vibrating diaphragm can be designed in the bottom of speaker or rear portion or front or Side Side, compared in this way, it vibrates area and can often be made
Greatly.In this way, promoting the volume of air to be consequently increased, this just greatly improves the amount sense of bass, meanwhile, the bore of passive vibrating diaphragm
Increase, additionally it is possible to reduce its resonant frequency, make speaker in sounding, obtain more preferable bass submerged depth.Like this, by compared with
Big passive vibrating diaphragm, even using toy trumpet, mini speaker, can also obtain preferable bass effect.And passive radiant panel
Material can but determine bass performance performance.
Currently used material is nitrile rubber (NBR) or butyl rubber (IIR) series rubber, but bass effect not very makes
People is satisfied with.
