Abstract
The present invention relates to a process for preparing material used for making a sound enclosure. Wood is mainly used for preparing the sound enclosure in the sound enclosure industry at present, and ceramic material is a little used for preparing the sound enclosure, which has the defects of large processing difficulty, poor sound effect, stiff appearance, no artistic attraction, high cost and market limitation. The present invention provides sound enclosure material which uses Magnesium chloride and Magnesium oxide as the main raw material for making the sound enclosure. The sound enclosure which is made of the material has advantages of simple technology, sound effect, good appearance, low cost, etc., and is formed one time. The material made is basically characterized in that the weight ratio of MgCl2: MgO equal to 1 to 99: 1 to 99 is proportionally mixed, which is formed by shaping and drying. The auxiliary materials of filling material, reinforcing ribs, etc. are added according to the design requirement of the sound enclosure, so the range of the material for making the sound enclosure is widened, and the market of the sound enclosure is greatly expanded.
Description
Technology neck city
The present invention relates to a kind of new material of making sound appliances, a kind of new material of making audio amplifier of definitely saying so.
Background technology
Make audio amplifier at present and mainly adopt sheet material in the sound equipment industry, with the most use is timber, makes the special casing of body by the acoustics requirement, the industrial processes manufacture difficulty is very big, generally all makes the regular square casing of shape, and acoustics is relatively poor, and the casing outward appearance is stiff, does not have artistic attraction; Some audio amplifier ceramic material, casing is because be ceramic material, and sound-absorbing effect is poor, and psycho-acoustical quality is bad, and the easily broken inconvenience transportation of pottery, and with the audio amplifier equipment cost height that this class material is made, market is limited to.
Summary of the invention
The objective of the invention is to: the new material that a kind of production technology making audio amplifier simple, with low cost is provided for the sound equipment industry; Can produce the senior audio amplifier equipment of outward appearance U.S., artistic value height, different shape that cost is low by the acoustics requirement with this kind material.
The objective of the invention is to realize by the enforcement following technical proposals:
A kind of new material of making audio amplifier, it is characterized in that: mainly form by magnesium chloride and two kinds of major ingredients of magnesium oxide and an amount of inserts and mixing water, wherein the weight proportion between major ingredient magnesium chloride and magnesium oxide was formed up to 99: 1 ratio in 1: 99, and an amount of inserts that adds can be saw chaff, stone flour, resin, each material of perlite;
Additional technical feature is: in the composition of this kind new material reinforcement can also be arranged, reinforcement can be bamboo bar, bamboo fibre, plastics, each material of glass fibre.
The present invention makes the new material of audio amplifier, by the requirement of audio amplifier design to material, mixes on the basis at major ingredient magnesium chloride and magnesium oxide, doses inserts such as saw chaff, stone flour, perlite, resin, forms through the moulding of water mix; Can also increase reinforcements such as filling out bamboo fibre, glass, plastics silk according to designing requirement.What major ingredient was mixed with is the production material of audio amplifier material; The adding of inserts mainly is to transfer heavy, reduction material cost, and reinforcement is mainly regulated material structure intensity.
The invention has the advantages that: raw material is easy to get, the preparation method is simple, can mold production, cost of manufacture is low, not only can produce audio amplifier sheet material, can also widen market by the high-grade artistic audio amplifier of die production abnormity.
Embodiment
Embodiment 1: the making of the audio amplifier assembly unit material of no reinforcement
The major ingredient magnesium chloride mixes by 1: 1 weight ratio with magnesium oxide, adds an amount of saw chaff again, and blunge is even, is not rare not thick pasty state production material, will produce and expect to place to shakeout drying and moulding on the flat board, and this kind sheet material can be used as the assembly unit sheet material of square audio amplifier.Also can expect that pouring the one-shot forming of audio amplifier mould into makes sound box with producing.
Embodiment 2: the making of the audio amplifier assembly unit material of reinforcement is arranged
The major ingredient magnesium chloride mixes by 1: 1 weight ratio with magnesium oxide, add an amount of saw chaff again, blunge is even, be not rare not thick pasty state production material, place dull and stereotyped going up to shakeout to certain thickness by designing requirement in this material, glass fabric again tiles, spread one deck production material by designing requirement again above the glass fabric, produce on the material and arrange bamboo bar or bamboo fibre at a certain distance, material is produced in tiling on request again, and drying and moulding is a sheet material.This kind sheet material can be used as the assembly unit sheet material of large-scale audio amplifier more than 0.5 cubic metre or the Speaker panel of special-shaped audio amplifier.Also can directly reinforcements such as glass fibre be inserted to reinject in the mould and produce the material one-shot forming.
Embodiment 3: a kind of making of high magnesia content audio amplifier material
The major ingredient magnesium chloride mixes with the weight proportion of magnesium oxide by 1: 99, adds an amount of resin and water and mixes the production material, expects to pour into to be pressed into required sheet material of audio amplifier or profile shapes in the mould with producing, and is assembled into square or special-shaped audio amplifier then.
Embodiment 4: a kind of making of high content of magnesium chloride audio amplifier material
The major ingredient magnesium chloride mixes with the weight proportion of magnesium oxide by 99: 1, adds an amount of stone flour and water and stirs into the production material, makes moulding.
Embodiment 5: the making of spherical sound material
Above any one produced material puts into the dome-type mould, putting into before according to the mould size decision add reinforcement how much, compression moulding or air dry moulding again is integrally combined two hemisphere after the moulding again, promptly becomes sound box.
Embodiment 6: a kind of high-quality audio amplifier material with one deck reinforcement
This material is made of internal layer and skin, internal layer adds inserts saw chaff by major ingredient magnesium chloride and magnesium oxide and mixes and form, outer add the inserts stone flour by major ingredient magnesium chloride and magnesium oxide and mix and form, the ectonexine intersection is the reinforced layer structure of being made up of glass fabric and bamboo bar.
Embodiment 7: a kind of high-quality audio amplifier material with multilayer reinforcement
This material is made of inside and outside layer, internal layer mixes and forms for added inserts saw chaff by major ingredient magnesium chloride and magnesium oxide, the internal layer intermediate reach is furnished with several layers of glass cloth and bamboo bar reinforcement, outer add the inserts stone flour by major ingredient magnesium chloride and magnesium oxide and mix and form, outer intermediate reach is furnished with several layers of glass cloth and bamboo bar reinforcement.
Claims (2)
1, a kind of new material of making audio amplifier, it is characterized in that: mainly form by magnesium chloride and two kinds of major ingredients of magnesium oxide and an amount of inserts and mixing water, wherein the weight proportion between major ingredient magnesium chloride and magnesium oxide was formed up to 99: 1 ratio in 1: 99, and an amount of inserts that adds can be saw chaff, stone flour, resin, each material of perlite
