Abstract
The utility model discloses a little gravity voice coil loudspeaker voice coil, including speech coil framework, hydrogen bag, pure iron core, insulating layer, coil, the hydrogen bag sets up the centre at speech coil framework, the pure iron core sets up the centre at the hydrogen bag, the insulating layer sets up the surface at speech coil framework, the coil winding sets up the surface at the insulating layer. This voice coil loudspeaker voice coil simple structure easily realizes, aluminium alloy material's speech coil framework, the rigidity is strong, light in weight and non -deformable, setting up of pure iron core can increase intensity of overflow tank, the hydrogen bag set up the weight that can alleviate whole device, make vibration effect better, it is more perfect to pronounce.
Description
Technical field
The utility model belongs to voice coil loudspeaker voice coil technical field, is specifically related to a kind of little gravity voice coil loudspeaker voice coil.
Background technology
Voice coil loudspeaker voice coil is the coil by tone currents, is 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.
When be in loud speaker magnetic field intensity be voice coil loudspeaker voice coil in the magnetic gap of B pass to electric current I time, voice coil loudspeaker voice coil can be subject to an electric power F=BLI (L is voice coil loudspeaker voice coil length), and Impact direction is by left hand rule.
After stressed generation, when the vibrational system comprising voice coil loudspeaker voice coil is vibrated with speed V, can produce induced voltage BLV in voice coil loudspeaker voice coil inside again, its direction meets the right-hand rule, props up mutually with the original sense of current.At this moment voice coil loudspeaker voice coil is the initiation person that damping produces, and is again the recipient of damping.
Voice coil loudspeaker voice coil in the past, owing to being subject to the restriction of gravity factor, can not be wound around too many coil, and cause magnetic force to produce not enough, thus cause the vibrations of voice coil loudspeaker voice coil undesirable, tone color, the volume of generation are of poor quality.
Utility model content
The purpose of this utility model is to provide a kind of little gravity voice coil loudspeaker voice coil, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of little gravity voice coil loudspeaker voice coil, comprise speech coil framework, hydrogen capsule, pure iron core, insulating barrier, coil, described hydrogen capsule is arranged on the centre of speech coil framework, described pure iron core is arranged on the centre of hydrogen capsule, described insulating barrier is arranged on the surface of speech coil framework, and described coil winding is arranged on the surface of insulating barrier.
Preferably, described speech coil framework is set to the skeleton of the one-body molded casting of aluminum alloy materials.
Preferably, hydrogen is filled with in described hydrogen capsule.
Preferably, described insulating barrier is set to ultralight insulator.
Preferably, winding that described coil is seamless is arranged on the surface of insulating barrier, and is wound around two-layer.
Technique effect of the present utility model and advantage: this voice coil structure is simple, be easy to realize, the speech coil framework of aluminum alloy materials, rigidity is strong, lightweight and not yielding, arranging of pure iron core can increase magnetic flux density, hydrogen capsule the weight that can alleviate whole device is set, make vibrating effect better, pronounce more perfect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, speech coil framework; 2, hydrogen capsule; 3, pure iron core; 4, insulating barrier; 5, coil.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides the little gravity voice coil loudspeaker voice coil of one as shown in Figure 1, comprise speech coil framework 1, hydrogen capsule 2, pure iron core 3, insulating barrier 4, coil 5, described hydrogen capsule 2 is arranged on the centre of speech coil framework 1, hydrogen is filled with in described hydrogen capsule 2, described speech coil framework 1 is set to the skeleton of the one-body molded casting of aluminum alloy materials, described pure iron core 3 is arranged on the centre of hydrogen capsule 2, described insulating barrier 4 is arranged on the surface of speech coil framework 1, described insulating barrier 4 is set to ultralight insulator, described coil 5 is wound around the surface being arranged on insulating barrier 4, the seamless winding of described coil 5 is arranged on the surface of insulating barrier 4, and be wound around two-layer.
Operation principle: the coil 5 of voice coil loudspeaker voice coil produces magnetic after passing into electric current, magnetic moves and drives the vibration of sound film to produce sound in magnetic field, insulating barrier 4 plays insulating effect, prevent electric current from outflowing and affect use, the speech coil framework 1 of aluminum alloy materials, rigidity is strong, lightweight and not yielding, arranging of pure iron core 3 can increase magnetic flux density, hydrogen capsule 2 the weight that can alleviate whole device is set, make vibrating effect better, pronounce more perfect, whole device is in increase structure, when increasing magnetic flux density, weight does not but increase, and voice effect is more good.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
