Abstract
The present invention is voice coil made with epoxy resin cloth and through once formation. The voice coil has the advantages of smooth appearance, high strength, high insulating performance, easy installation, free vibration in loudspeaker and high elasticity and good acoustic effect.
Description
Technical field: what the present invention relates to is that epoxy resin cloth is used to make voice coil loudspeaker voice coil, and dominant circle product is made the field.
Background technology:
Publication number CN1172185A, title " a kind of production method for voice coil paper ", it comprises operations such as PUR is coated with, cuts, it is characterized in that before coating, earlier paper substrates being carried out supercalendering handles, increase the tightness and the elasticity of paper substrates, and paper substrates all is tubular or plate-like in each operation such as supercalendering, PUR are coated with, cut.The deficiency that exists: the one, intensity difference easily loses circle, and the 2nd, the modification of making moist easily influences the voice coil loudspeaker voice coil performance, and the 3rd, poor flexibility is installed trouble.
At present, the voice coil loudspeaker voice coil that sale and electroacoustic factory use on the market adopts plumbous thin mould circle to make shape, though this voice coil loudspeaker voice coil has overcome the deficiency in the CN1172185A technical scheme.But the difficult problem that can't overcome is in actual applications: electric leakage easily, easily lose circle, and difficulty is installed.
Summary of the invention:
Purpose of design of the present invention, avoid the weak point in the background technology, design and a kind ofly can fully satisfy under the prerequisite of voice coil loudspeaker voice coil intensity, not only voice coil loudspeaker voice coil makes moist and any distortion can not take place under the situation, and can fundamentally solve voice coil loudspeaker voice coil and easily leak electricity, easily lose circle, a difficult difficult problem of installing.In order to realize purpose of design of the present invention, the present invention selects at the material of voice coil loudspeaker voice coil, go through repetition test and the test of several years, find employing glass fabric and resin base material as voice coil loudspeaker voice coil, and through the prepared epoxy resin cloth coil of the hot setting once-forming demoulding, flat appearance not only, intensity is good, do not lose circle, and insulation property is excellent, easy for installation, solve the insurmountable difficult problem of background technology, and in loud speaker, vibrated freely good springiness, reduce the trouble of installation personnel, fundamentally remedied the deficiency on the voice coil loudspeaker voice coil for many years.Its technical scheme: 1. epoxy resin cloth coil, be tied with coil (1) on the voice coil loudspeaker voice coil (2), voice coil loudspeaker voice coil (2) is one-time formed epoxy resin cloth.2. the preparation method of epoxy resin cloth coil, at first on the voice coil loudspeaker voice coil mould, be coated with and wax, then glass fabric is entangled on the voice coil loudspeaker voice coil mould and coats resin, coat plastic film thereon again after, through 160 ℃～200 ℃ hot settings and the once-forming demoulding, promptly constitute epoxy resin cloth coil.Adopt the made epoxy resin cloth coil of technique scheme to compare with background technology, the one, flat appearance not only, intensity is good, does not lose circle, and insulation property are excellent, and is easy for installation, solved the insurmountable difficult problem of background technology; The 2nd, this voice coil loudspeaker voice coil vibrates freely in loud speaker, good springiness has reduced the trouble of installation personnel, and has fundamentally remedied the deficiency on the voice coil loudspeaker voice coil for many years, has obtained beyond thought acoustics.
Description of drawings:
Fig. 1 is the structural representation of epoxy resin cloth coil.
Fig. 2 is the preparation method's of epoxy resin cloth coil a block diagram.
Embodiment:
Embodiment 1: with reference to accompanying drawing 1.Epoxy resin cloth coil is tied with coil (1) on the voice coil loudspeaker voice coil (2), voice coil loudspeaker voice coil (2) is one-time formed epoxy resin cloth.
Embodiment 2: the preparation method of epoxy resin cloth coil, at first on the voice coil loudspeaker voice coil mould, be coated with and wax, then glass fabric is entangled on the voice coil loudspeaker voice coil mould and coats resin, after coating plastic film thereon again, through 160 ℃～200 ℃ hot settings and the once-forming demoulding, promptly constitute epoxy resin cloth coil.Scribble resin between glass fabric and glass fabric.
Claims (3)
1, a kind of epoxy resin cloth coil is tied with coil (1) on the voice coil loudspeaker voice coil (2), it is characterized in that: voice coil loudspeaker voice coil (2) is one-time formed epoxy resin cloth.
2, a kind of preparation method of epoxy resin cloth coil, it is characterized in that: at first on the voice coil loudspeaker voice coil mould, be coated with and wax, then glass fabric is entangled on the voice coil loudspeaker voice coil mould and coats resin, after coating plastic film thereon again, through 160 ℃～200 ℃ hot settings and the once-forming demoulding, promptly constitute epoxy resin cloth coil.
