The utility model content:
The purpose of this utility model provide have that tonequality is good, sound is loud and clear, a kind of high-fidelity giant magnetostrictive transducer of characteristics such as dependable performance, simple in structure and prestressing force are conveniently adjusted.
Scheme of the present utility model is: steel ingot axially is shaped on through hole, the skeleton that is with coil is installed in the steel ingot through hole, be provided with super-magnetostrictive drive in the skeleton pipe, super-magnetostrictive drive is alternately connected with permanent magnet by many super mangneto rare earth rods and is constituted, and two ends are permanent magnet.
The super-magnetostrictive drive two ends respectively are with tapered cap, and upper conical cap is conflicted with the sounding base plate that is enclosed within the steel ingot upper end, and the screw of inferior pyramidal cap and steel ingot bottom is conflicted.Steel ingot is the bigger cylinder bloom of volume, and outer wall is provided with the heat radiation cover.The cross section of skeleton, coil, super mangneto rare earth rod and permanent magnet is square.
The utility model has the advantages that: adopt the giant magnetostrictive transducer of such scheme simple in structure, sound is loud and clear, and tonequality is better, good heat dissipation effect, dependable performance; Transducer prestressing force is regulated easy, can directly be placed on the vibrating body and use, and is very convenient.
Description of drawings:
Fig. 1 is the axial cutaway view of the utility model.
Fig. 2 is square skeleton 7 transverse sectional view.
Embodiment:
With reference to Fig. 1, steel splits 2 for cylinder, and outer wall is with heat radiation cover 9, axially is shaped on through hole, and the through hole bottom is provided with screwed hole, and screw 1 is installed on the screwed hole place.The skeleton 7 that is with coil 8 is installed in the above-mentioned through hole, is provided with super-magnetostrictive drive in the skeleton 7.This super-magnetostrictive drive is alternately connected by 6 and four permanent magnets of three super mangneto rare earth rods 5 and is constituted, permanent magnet 5 outsides at two ends all are with tapered cap 4, the inferior pyramidal cap is conflicted with the screw 1 that is installed on steel ingot 2 through hole bottoms, and upper conical cap is conflicted with the sounding base plate 3 that is placed in steel ingot 2 upper ends.The compound mode of super mangneto rare earth rod 6 and permanent magnet 5 has multiple, also can be two or three combinations or four or five combinations etc.
With reference to Fig. 2, the cross section of skeleton 7 is square, and the cross section of super mangneto rare earth rod 6, permanent magnet 5 and the coil 8 that matches all is arranged to square.Certainly, also can be arranged to other shapes such as circle, ellipse, rectangle, and square rare earth rod working (machining) efficiency is the highest.
Operation principle: the AC signal of a certain sound source output is through behind the amplifying circuit, flow into coil 8, produce alternating magnetic field, the variation that is positioned at the super-magnetostrictive drive response current signal of magnetic field center produces the vibration of high frequency ultra-magnetic telescopic, the high frequency of vibration by 4 pairs of sounding base plates 3 of tapered cap knocks and passes to sounding base plate 3 and sound, and sounding base plate 3 contacts further with planar vibrating bodies such as desktop or metopes sound is amplified.
Adopt the following advantage that the utlity model has of said structure:
1, the permanent magnet 5 of magnetostrictor and super mangneto rare earth rod 6 is carried out the alternately mode of arranged in series, strengthens the effect that the transducer electroacoustic transforms, thereby makes the Distribution of Magnetic Field in the whole ultra-magnetic telescopic drive system more even; Meanwhile, this kind arrangement mode makes super-magnetostrictive drive be greatly improved with respect to the sensitivity of changes of magnetic field, realizes the output of high-power Hi-Fi audio signal.
2, with steel ingot 2 ccontaining super-magnetostrictive drives, the screw of steel ingot 2 bottoms 1 compresses driver, thereby makes audio signal truly pass to the sounding parts efficiently by electromagnetic transducer.By to screw 1 prestressed adjusting, realize adjusting simultaneously, amplify and output effect to reach best audio frequency to the super-magnetostrictive drive Oscillation Amplitude.
3, the big Heavy Weight of steel ingot 2 volumes is applied on the sounding base plate 3 by self weight, and it is more tight that sounding base plate 3 is contacted with vibrating bodies such as desktop, metopes, thereby transmit mechanical oscillation more expeditiously, increases the effect that the transducer electroacoustic transforms.
4, adopt the tapered cap 4 of conical design, the high-frequency mechanical vibration of super-magnetostrictive drive can be accumulated on the very little point of area, high frequency by 4 pairs of sounding base plates 3 of tapered cap knocks then, amplifies Oscillation Amplitude, obtains audio signal output effect preferably.
5, in view of the lower characteristics of circular rare earth rod working (machining) efficiency, the rare earth rod 6 of this transducer is processed into square, and the permanent magnet 5 that matches with rare earth rod 6, coil 8, skeleton 7 all are set to square.The shape that coil 8 produced and passed the magnetic line of force intensity distributions of rare earth rod 6 also is similar square configuration, consistent with rare earth rod 6 shapes, the magnetic field intensity that is distributed on the rare earth rod 6 is even, makes rare earth rod 6 stressed comparatively even, changes the signal of telecommunication into rare earth rod high-frequency mechanical vibration uniformly.
6, be with the heat radiation cover 9 of annular at the outer wall of steel ingot 2, the area of heat radiation is improved significantly with respect to original steel ingot 2 surfaces; Like this, the heat that produces on the coil 8 just can not accumulate in above the steel ingot 2, can in time realize heat radiation by heat radiation cover 9, prolongs the useful life of transducer.
