Description

Super sound transmitter

Technical field

The present invention relates to microphone and dull and stereotyped loudspeaker techniques in the stereo set field, it is on the basis of ultra-magnetic telescopic audio-frequency transducer, the super sound conduction high-tech new product of developing that all can apply in a flexible way in numerous places such as office, commerce, study, amusements.

Background technology

Super sound transmitter be attached to desk, cupboard, furniture, and object such as building on a kind of the transducing transmitter of shaking, the almost penetrable any rigid objects of its sound conduction transmits sound in various spaces.The technical bottleneck that the Hz-KHz that this sound equipment pattern of utilizing solid-borne sound transmission has been broken traditional moving-coil type sound equipment pattern is narrow, directive property sharp-pointed and restriction loud speaker such as transient distortion further develops, create novel solid-borne noise conduction loud speaker, become the important breakthrough in loudspeaker techniques field.The development of solid-borne noise conduction loud speaker is closely bound up with the development of panel speaker energy-conversion technique.Be the NKT panel speaker of Britain Verity company the earliest, what it adopted is electromagnetic transduction, and the employing of NCT company is piezoelectric ceramic transducer, loud speaker is in light weight, sound equipment frequency band broad, tonequality height, the sound aphalangia to, stereomicrophone system does not need audio amplifier, has started the beginning of ultrathin panel speaker commodity on the contemporary market, and this has also opened up the pattern of innovation for the development of sound transmitter.

Now with the rareearth super magnetostrictive alloy as the audio frequency transductive material, the application on panel speaker is a quantum jump of loud speaker manufacturing technology, has remedied the drawback of conventional loudspeakers better.Utilize the rareearth super magnetostrictive alloy of our independent research for many years and the practice explanation of application thereof, the application of the outstanding characteristic of this transductive material in panel speaker harmony transmitter product has special advantages.With respect to piezoelectric ceramic is the panel speaker of driving element, the transductive material of making of the rareearth super magnetostrictive alloy is under the effect in tone currents magnetic field, its magnetostriction output variable surpasses the piezoelectric ceramic field and causes stroke more than 5 times, energy density is big, response speed to magnetic field is exceedingly fast, reach the microsecond level, and do not exist piezoelectric ceramic easily to lose extremely aging and high electrical breakdown phenomenon.The electromagnetic type panel speaker then easily produces nonlinear distortion, and frequency characteristic is relatively poor, and power is little.More demonstrated the outstanding characteristic of big magnetostriction panel speaker by contrast.It has, and the output energy is big, and response speed is fast, bandwidth, and fidelity is good, and particularly the power output of ultra-magnetic telescopic transductive material is big, can directly drive very large-area rigid objects aphalangia to vibration sounding.Therefore, utilize " super sound transmitter " new product that uses in various places of ultra-magnetic telescopic transductive material research and development, it is simple and compact for structure, volume is frivolous small and exquisite, and have outstanding acoustics, almost can in various spaces, implement the no barrier transmission of high-fidelity signal by any rigid objects.Make it reach omnibearing hearing effect, expanded the flexible Application of super sound transmitter in numerous places such as office, commerce, study, amusements.

Summary of the invention

The present invention utilizes the ultra-magnetic telescopic alloy to be transductive material, " super sound transmitter " new product that uses in various places of developing, its architectural feature as shown in Figure 1, form by bottom (7), body (9) control panel (11), body (9) is provided with interface (10), the control system of variety of way and purposes can be set on the control panel (11) as required, and rare-earth super-magnetic causes transductive material and is arranged in the interior magnetic conductor (8) of body (9), vibrates by bottom (7) output audio.According to the needs of different places, utilize modes such as gluing, sucker, clamp or screw thread with super sound transmitter attached to resonance sounding on the suitable object in various places, before having eliminated in unintelligible, the slack phenomenon of the speech exchange in various places.

Technique effect of the present invention: be to utilize the original rigid objects in various places as the pronunciation medium---for example the glass of bank's business window just can be directly as the pronunciation medium of super transmitter, just pronounce as same dynamic planar loudspeakers by solid conduction with large tracts of land pronunciation, form 360 degree aphalangias to sound producing pattern, has bandwidth, high-fidelity, the outstanding characteristic of stereo and superpower volume, thereby all can reach audibility on an equal basis clearly inside and outside making window, interchange in the window is not just as there being in-plant face-to-face exchange under the state of glass barrier, and it is unintelligible to have eliminated the inside and outside speech exchange of window, slack phenomenon.Because the miniaturization and the integrated good combination of built-in miniature MIC thereof of super sound transmitter, cause its compact conformation, volume is small and exquisite, exquisite, install, easy to use, this has fundamentally improved, and the existing a plurality of loud speakers that exist with cone loudspeaker intersect with line between the loud speaker, the inconvenient indecency part of occupy-place dispersion.Through the described all kinds of super sound transmitter of a large amount of evidence this patents, its transaudient and integrated combination of function of raising one's voice, simple and compact for structure, volume is small and exquisite.It is big that rare-earth super-magnetic causes transductive material power, the energy height, can drive very large-area rigid objects aphalangia to resonance sounding, it is used in commerce, finance, traffic, office, study, and numerous places such as outdoor media are just as superhuge dynamic planar loudspeakers has been arranged, and sound does not have hysteresis quality, the comprehensive pronunciation of 360 degree, response band is wide, the fidelity height, it is very clear no matter all can to enjoy in any orientation of pronunciation medium, soft sound effect, people have fundamentally been solved noisy, the aphthenxia that occurs when having places such as barrier and scope be bigger to exchange is clear, the undesirable condition of not smooth and transaudient inconvenience, the convenience that therefore super sound transmitter brings for various places, flexibly, be suitable for the outstanding effect that has just demonstrated fully after updating.
