Abstract
The invention discloses a preparation method for a high-power-resistant great-resilience type damper. The method specifically comprises the steps of (1), weaving into a cloth body 1 by using copper wires as warps and Dacron as wefts; (2), proportionally adding phenolic resin and butyl etherified resin into a methanol solution, after adding, fully stirring to dissolve, and thus obtaining prepared liquid 2; (3) immersing the cloth body 1 into the prepared liquid 2, taking out the cloth body 1 and draining off the excess solution, and placing the cloth body 1 into a hot pressing die for hot pressing; and (4), immersing the cloth body 1 well processed in the step (3) into the dilute prepared liquid 2 again, placing the cloth body 1 into the hot pressing die for hot pressing after taking out from the solution and draining off the excess solution, and then sending into a vacuum oven for drying. The preparation method has the advantages that the copper wires and Dacron are used as substrates to form the cloth, the specially configured resin solution is used for fixing the shape, and the prepared damper has the advantages of being resistant to high power and great in resilience.
Description
Technical field
The present invention relates to domestic loudspeaker box accessory manufacturing technology field, the system of a kind of resistance to high power reply type by force bullet ripple
Preparation Method.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that audio frequency electric energy is converted into corresponding acoustic energy, and its spoke
It is mapped to space go.It is the extremely important ingredient of sound system, the signal of telecommunication can be transformed into acoustical signal.
Speaker of voice box is one of core component of audio amplifier, and the quality of its performance is bigger to audio amplifier performance impact.And play ripple
Being the important component part of speaker system, the tonequality of speaker is had a certain impact by the relevant vibrations coefficient playing ripple.Its tool
There is holding voice coil loudspeaker voice coil tram in magnetic gap, it is ensured that voice coil loudspeaker voice coil vibrational system when stress moves axially in reciprocal fashion, and vibration system
The voice coil loudspeaker voice coil of system, vibrating diaphragm together decide on the resonance efficiency of speaker, moreover it is possible to prevent dust from entering magnetic gap.But the bullet ripple being typically prepared
Resistance under audio amplifier high-power operation state is poor, and physical restoration is the most poor.
Summary of the invention
It is an object of the invention to, for solving the problems of the prior art, disclose a kind of resistance to high power reply type by force bullet ripple
Preparation method.
For achieving the above object, the invention discloses the preparation method of a kind of resistance to high power reply type by force bullet ripple, it is concrete
Step is:
(1) with the copper cash of diameter 1-3mm as warp, terylene is that parallel is woven into cloth body 1；
(2) phenolic resin and fourth etherified resin are joined in the methanol solution of 60% concentration according to the ratio of 5:1, two kinds of resins
Addition is the 20-40% of methanol solution quality, is sufficiently stirred for dissolving and within 10-15 minute, obtains preparing liquid 2 after addition；
(3) being immersed in by cloth body 1 in preparation liquid 2, the time of immersing continues 1-2 hour, drains redundant solution, insert hot pressing after taking-up
Mould carries out hot pressing, hot pressing temperature 140-160 DEG C, continues 1-2 hour；
(4) it is again dipped into being diluted in the preparation liquid 2 of 80% concentration by the cloth body 1 handled well in step (3), immerses time 2-3 little
Time, take out and after draining, insert hot pressing 20-30 minute in hot-die, hot pressing temperature 180 DEG C, send into afterwards in vacuum drying oven and dry 1-
2 hours, dry temperature 120-140 DEG C.
Advantages of the present invention and good effect be:
The inventive method copper cash and terylene are that ground becomes cloth, and with the resin solution curable type of particular arrangement, the bullet ripple prepared
There is resistance to high power, the advantage having strong reply type.
