Description
Technical field
This utility model relates to speaker field, is specifically related to a kind of 360 ° of comprehensive sounding tweeters.
Background technology
In recent years, development along with electronics technology industry and material science, acoustic electronic product miscellaneous obtains the direction of conventional high-fidelity sounding to be developed, but it is applied in such as various fever sound equipments, automobile audio, speaker on the electronic products such as television set, sounding propagation is carried out owing to speaker and sound box are positioned over same plane, in order to provide high-quality sounding effect better, it will to acoustics phase place, speaker pendulum position, loudspeaker diaphragm materials, electronic device and power amplifier etc. continue to study improvement, the development of the speaker of conventional acoustic principle, sound quality often improve little by little all difficult incomparably, run into unprecedented Sound Development bottleneck, thus more pleasing to the ear audible device sound of having reset cannot be allowed to carry out technological innovation.
Haier doctor (OscarHeil) utility model of the U.S. in 1973 a kind of special speaker acoustic irradiation mode---AMT (AirMotionTransformer) pneumatic type transducer, i.e. Haier's formula speaker.Its operation principle is to have a piece of special insulation film in the middle of two magnetic poles, film surface is covered with one layer by the wire coil necessarily moving towards arrangement, and the vibrating diaphragm assembly folded up as accordion, each adjacent face of folding diaphragm does relative motion in magnetic field, from crimple extrusion or suction air, radiative acoustic wave in the way of injection.
The occurring mode of Haier's formula speaker is air is by spouting in the gap folded, just as extruding tablees tennis push away, than with one palm, the farther reason faster that can run with two fingers, energy than vibrating diaphragm direct shake in atmosphere faster higher.According to the measurement of doctor Heil, speed is about 5 times of common Dome loudspeaker.It is careful that excellent characteristic makes Haier's speaker have, solid, straightforward, limpid, sweet details of not losing again, resolves power high, and precisely, dynamically greatly, the first-class performance that wink property is good, for one of generally acknowledged high pitch loudspeaker top-ranked unit.Such as: listen guitar, piano etc. to play happy spatial impression bigger, violin can keep wood taste and trickle rustle, fizz wait overtone details, constitute real texture, the magnetic voice that people's acoustic energy real surface is existing careful, particularly the performance when big signal is superior especially.
But Haier's manufacture process of speaker is complicated, and price is high, it is difficult to universal.Tradition one side sounding simultaneously, before and after even, sounding is respectively provided with sound transmission dead angle, propagates the strong and weak difference having sound wave to human ear, and the air of driving is limited, distortion rate is higher, it is impossible to improve further field of audio voice quality more truly, more natural, the technical merit that more shakes.

The purpose of this utility model is to be achieved through the following technical solutions:
A kind of 360 ° of comprehensive sounding tweeters, including magnetic structure, described magnetic structure includes first annular magnetic conduction ferrum and is installed in the second annular magnetic conduction ferrum outside it with set, it is provided with high energy Magnet and annular diaphragm group between described first annular magnetic conduction ferrum and the second annular magnetic conduction ferrum, described high energy Magnet is symmetricly set on the both sides up and down of described first annular magnetic conduction ferrum, and described annular diaphragm group is arranged between upper and lower two described high energy Magnet.
Further, described annular diaphragm group includes folding diaphragm and annular diaphragm frame, described folding diaphragm is fixed on the outside of described annular diaphragm frame, and described annular diaphragm frame is annular solid, and its outside side wall is provided with the projection matched with the gully on described folding diaphragm.
Further, described folding diaphragm is by suppressing one layer of aluminium foil or Copper Foil on resistant to elevated temperatures insulation film sheet, is then passed through in chemical etching voice coil loudspeaker voice coil and is flexed into many folding shapes forming.
Further, connect each through seccotine is fixing between described first annular magnetic conduction ferrum, high energy Magnet and the second annular magnetic conduction ferrum.
Further, the outer lateral side of described second annular magnetic conduction ferrum is provided with some strip through-holes, for radiative acoustic wave, has effect attractive in appearance simultaneously.
Further, the top and bottom of described magnetic structure is respectively equipped with upper cover and underframe, outside making described magnetic structure be directly exposed to, increases aesthetics, makes the sound wave that described annular diaphragm group sends directly be issued in space, it is ensured that the quality of sound.
The beneficial effects of the utility model are:
1, this utility model realizes Haier is sprayed loudspeaker being designed to 360 degree of comprehensive tunes, it is achieved real playing effect be truly realized when image documentation equipment reduce direct projection, reflection, complexity and richness overtone sound restore really.
2, this utility model passes through 360 ° of comprehensive sounding, and sounding effect is splendid, it is implemented without deliberately putting position and just can build a both wide and deep huge sound field, the superpower audition not having highly directive is experienced, the true effect that reproduction nature, music hall are heard, existing substantial amounts of direct projection sound, also there is very abundant reflected sound, can well obtain immenseer spatial impression, more real stage sense and knot image force, making it be more suitable in the listening environments that space is undesirable to use, it is provided that true and detailed 3 D stereo acoustic imaging.
3, folding diaphragm is surrounded annular by this utility model, increases vibrating diaphragm area, increases air drive volume, it is achieved vibrating diaphragm amplitude is little, and vibration velocity is fast, and sound transfer rate is faster.
4, this utility model impedance curve is straight, and power drives greatly and easily, and distortion is lower.
