Abstract
The utility model discloses a voice coil loudspeaker voice coil structure based on glass fiber pipe uses, including the main structure body, the main structure body includes speech coil framework, speech coil framework is glass fiber pipe, glass fiber pipe is prepared from glass fiber cloth, speech coil framework is equipped with the enameled wire outward, the enameled wire connection sets up the pin. The tone quality effect is better, adopts glass fiber pipe preparation speech coil framework, and is high temperature resistant, under 300 DEG C high temperature environment, even the burning of copper line can not affect the voice coil loudspeaker voice coil main part, effectively avoids the whole trouble of the whole voice coil loudspeaker voice coil of high temperature burning initiation, has avoided the potential safety hazard.
Description
Technical field
The utility model relates to voice coil designs field, particularly relates to a kind of voice coil structure based on fiberglass pipe application.
Background technology
Voice coil loudspeaker voice coil (VoiceCoil) directly definition is the coil by tone currents, and being the important component part of dynamic speaker vibrational system, is alternatively the heart of loud speaker.The performance of voice coil loudspeaker voice coil can affect the sound pressure frequency characteristic of loud speaker, sound pressure level, impedance curve, distortion, transient response, loudspeaker parameters, tonequality etc., particularly relation loud speaker bear power and life-span.The lethal factor of erect image heart disease is the same, and the damage of loud speaker is often from voice coil loudspeaker voice coil.
The important component part of voice coil loudspeaker voice coil is the enamelled wire of metal structure, such as copper cash, but voice coil loudspeaker voice coil in use, this structure is easy to because the problems such as fault cause high-temp combustion, the materials such as traditional speech coil framework many employings brown paper are prepared from, cannot be high temperature resistant, easily cause burning of whole voice coil structure, be easy to cause the accident.
Summary of the invention
The purpose of this utility model is to provide a kind of voice coil structure based on fiberglass pipe application, effectively solves the problem.
For effectively solving the problems of the technologies described above, the technical scheme that the utility model is taked is as follows:
Based on the voice coil structure of fiberglass pipe application, comprise main structure body, described main structure body comprises speech coil framework, described speech coil framework is fiberglass pipe, described fiberglass pipe is prepared from by glass fabric, is provided with enamelled wire outside described speech coil framework, and described enamelled wire connection arranges pin.
Especially, described speech coil framework is cylindrical structural, and described enamelled wire and described speech coil framework wrap up covering and realize fixing.
Especially, described enamelled wire is by certainly melting enamelled wire, is made up of enamel-cover oxygen-free copper-wire, one of copper-clad aluminum conductor or fine aluminium.
Especially, described enamelled wire and be provided with reinforcement paper between described pin and described pin and achieve a fixed connection.
Especially, described main structure body also comprises the outer cover be made up of bright and beautiful silk thread.
Especially, described bright and beautiful silk thread is formed by gummed braiding after the winding of one or more sheet metal.
The beneficial effects of the utility model are: the voice coil structure based on fiberglass pipe application that the utility model provides, acoustical quality is better, fiberglass pipe is adopted to prepare speech coil framework, high temperature resistant, under the hot environment of 300 DEG C, even if copper cash burning, voice coil loudspeaker voice coil main body can not be fed through to, effectively avoid high-temp combustion to cause the overall failure of whole voice coil loudspeaker voice coil, avoid potential safety hazard.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 be in the utility model based on the composition structure chart of voice coil structure of fiberglass pipe application;
Wherein:
1 main structure body, 2 speech coil frameworks, 3 enamelled wires, 4 pins, 5 reinforcement paper.
Embodiment
Embodiment 1:
As shown in Figure 1, the disclosed voice coil structure based on fiberglass pipe application of the present embodiment, comprise main structure body 1, described main structure body 1 comprises speech coil framework 2, described speech coil framework 2 is fiberglass pipe, described fiberglass pipe is prepared from by glass fabric, is provided with enamelled wire 3 outside described speech coil framework 2, and described enamelled wire 3 connection arranges pin 4.
Described speech coil framework 2 is cylindrical structural, and described enamelled wire 3 and described speech coil framework 2 wrap up covering and realize fixing.Described enamelled wire 3 is by certainly melting enamelled wire, is made up of enamel-cover oxygen-free copper-wire, one of copper-clad aluminum conductor or fine aluminium.Described enamelled wire 3 and be provided with reinforcement paper 5 between described pin 4 and described pin 4 and achieve a fixed connection.Described main structure body 1 also comprises the outer cover be made up of bright and beautiful silk thread.After described bright and beautiful silk thread is wound around by one or more sheet metal, gummed braiding forms.
Know-why is as follows:
Overall structure acoustical quality is better, adopts fiberglass pipe to prepare speech coil framework, high temperature resistant, under the hot environment of 300 DEG C, even if copper cash burning, voice coil loudspeaker voice coil main body can not be fed through to, effectively avoid high-temp combustion to cause the overall failure of whole voice coil loudspeaker voice coil, avoid potential safety hazard.
Glass fibre is the non-conductive material that rigidity is very strong, and heat resistance is fine, and selected high-quality glass fibre is speech coil framework, and appearance coats resistant to elevated temperatures SV glue, is manufacture
hi-Fiwith the outstanding material of Hi-end loud speaker.The advantage of glass fibre is: be (1) non-conductor, without the harmful effect of electrically dropping down stream, (2) heat resistance is good, (3) good rigidly.Specific as follows:
For non-conductor, the harmful effect without electrically dropping down stream: the weak point of conductor speech coil framework be when voice coil loudspeaker voice coil have ac signal by time can produce magnetic field electrically drop down stream (votex) in metallic framework, cause energy loss, and can magnetic circuit system be affected.Glass fibre is not conductor, does not have the impact that stream (votex) is electrically dropped down in magnetic field, can the effective frequency range of broadening loud speaker.
Heat resistance is good: glass fibre is heat proof material, and glass fibre speech coil framework scribbles resistant to elevated temperatures SV glue in appearance, can not burn out glue in high-power situation, also can not be out of shape because of heating, and heat resistance is very outstanding.
Rigidity is large: glass fibre speech coil framework rigidity is very large, and surface not easily produces scar and folding line, also can not grain raising, and voice coil loudspeaker voice coil can be made forever to keep smooth, bright and clean, and use glass fibre voice coil loudspeaker voice coil that loud speaker can be made to assemble more convenient, efficiency is higher, and the quality of loud speaker is best.
The utility model is not limited to above-mentioned execution mode, and all employings and the utility model analog structure and method thereof realize all execution modes of the utility model object all within the utility model protection range.
