Description
Technical field
The present invention relates to loud speaker field, be specifically related to a kind of 360 ° of comprehensive sounding tweeters.
Background technology
In recent years, along with the development of electronics technology industry and material science, acoustic electronic product miscellaneous obtains the future development of high-fidelity sounding in the past, but be applied in such as various fever sound equipment, automobile audio, loud speaker on the electronic products such as television set, sounding propagation is carried out due to loud speaker and sound box are positioned over same plane, in order to provide high-quality sounding effect better, it will to acoustics phase place, loud speaker pendulum position, loudspeaker diaphragm materials, electronic device and power amplifier etc. carry out continuing research improvement, the development of the loud speaker of conventional acoustic principle, sound quality often improves little by little all incomparably difficult, 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.
The Haier doctor (OscarHeil) of the U.S. in 1973 has invented a kind of special loud speaker acoustic irradiation mode---AMT (AirMotionTransformer) pneumatic type transducer, i.e. Haier's formula loud speaker.Its operation principle is the insulation film having a slice special in the middle of two magnetic poles, film surface is covered with one deck by the wire coil necessarily moving towards to arrange, and the vibrating diaphragm assembly folded up as accordion, each adjacent face of folding diaphragm does relative motion in magnetic field, extrude from crimple or suck air, with the mode radiative acoustic wave sprayed.
The occurring mode of Haier's formula loud speaker is air is by spouting in the gap folded, just as with two finger extruding table tennis than the farther reason faster pushing away can run with a palm, energy Ratios vibrating diaphragm directly shakes will come stronger sooner in atmosphere.According to the measurement of doctor Heil, speed is approximately 5 times of common Dome loudspeaker.It is careful, solid, straightforward, limpid that excellent characteristic makes Haier's loud speaker have, and sweetly do not lose details again, and power of resolving is high, and precisely, dynamically greatly, the first-class performance that wink property is good is one of high pitch loudspeaker top-ranked unit of generally acknowledging.Such as: listen guitar, piano etc. to play happy spatial impression larger, violin can keep wood taste and tricklely to rustle, fizz wait overtone details, form real texture, the magnetic voice that people's acoustic energy real surface is existing careful, the performance particularly when large signal is superior especially.
But Haier's manufacture process of speaker is complicated, and price is high, is difficult to popularize.Traditional one side sounding simultaneously, even, sounding all has sound transmission dead angle, and propagate into the strong and weak difference that people's ear has sound wave, the air of driving is limited, distortion rate is higher, cannot improve further field of audio voice quality more truly, more natural, the technical merit that more shakes.
Summary of the invention
The object of this invention is to provide a kind of 360 ° of comprehensive sounding tweeters, realize loud speaker 360 ° of comprehensive sounding, and sounding effect is splendid, greatly increase vibrating diaphragm area, vibrating diaphragm amplitude is little, and vibration velocity is fast, and distortion is lower.
The object of the invention is to be achieved through the following technical solutions:
A kind of 360 ° of comprehensive sounding tweeters, comprise magnetic structure, described magnetic structure comprises the first annular magnetic conduction iron and overlaps the second annular magnetic conduction iron be installed in outside it, high energy magnet and annular diaphragm group is provided with between described first annular magnetic conduction iron and the second annular magnetic conduction iron, described high energy magnet is symmetricly set on the both sides up and down of described first annular magnetic conduction iron, and described annular diaphragm group is arranged between upper and lower two described high energy magnet.
Further, described annular diaphragm group comprises 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 suppresses one deck aluminium foil or Copper Foil by resistant to elevated temperatures insulation film sheet, then voice coil loudspeaker voice coil be flexed into many folding shapes and form in chemical etching.
Further, described first annular magnetic conduction iron, be all fixedly connected with by seccotine between high energy magnet with the second annular magnetic conduction iron.
Further, the outer lateral side of described second annular magnetic conduction iron 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, and make outside described magnetic structure is directly exposed to, increase aesthetics, the sound wave that described annular diaphragm group is sent directly is issued in space, ensures the quality of sound.
Beneficial effect of the present invention is:
1, the present invention realizes loudspeaker is sprayed in Haier being designed to 360 degree of comprehensive tunes, realize real playing effect really accomplish when image documentation equipment reduces direct projection, reflection, complexity and rich overtone sound restore really.
2, the present invention is by 360 ° of comprehensive sounding, and sounding effect is splendid, realize not needing deliberately putting position just can build a both wide and dark huge sound field, there is no the superpower audition impression of highly directive, the true effect that reproduction nature, music hall are heard, existing a large amount of direct projection sound, also very abundant reflected sound is had, can well obtain immenseer spatial impression, more real stage sense and knot image force, make it be more suitable for using in the listening environments that space is undesirable, it can provide true and detailed 3 D stereo acoustic imaging.
3, folding diaphragm is surrounded annular by the present invention, increases vibrating diaphragm area, increases air driven amount, realizes vibrating diaphragm amplitude little, and vibration velocity is fast, and sound transfer rate is faster.
4, impedance curve of the present invention is straight, and greatly and easily drive, and distortion is lower for power.
