[background technology]
In recent years market occurs a kind ofly having overturned the resonance speaker of people to traditional sound equipment concept understanding, the sonification system of this resonance speaker itself does not have vibrating diaphragm, it utilizes the principle of resonance, audio signal is converted into audio frequency mechanical oscillation, export to any hard objects contacted with it, make this hard objects as sound production medium sounding, it is evenly gentle in voice, non-directive, in 360.Around sounding, and different tamber effects can be formed according to different sound production mediums.The volume of resonance speaker is little, can arbitrarily put, and its only needs to be connected with the audiogenic device such as computer, MP3, MP4, MD, CD, DVD player, mobile phone, and the hard objects such as desk, door, window, floor in daily life just can be allowed to become natural sound equipment.Existing resonance speaker mainly comprises shell, base, leads the support that shakes, magnet, giant magnetostrictive rod, coil, coil brace etc., shell is connected with base screw lock, lead the support that shakes and be fixed on base lower end, magnet, giant magnetostrictive rod, coil and coil brace are placed in shell, on the sheathed subcoil support of coil, giant magnetostrictive material is positioned over coil brace central authorities, magnet is placed in the two ends up and down of coil brace, and the two ends up and down of giant magnetostrictive material are pushed up mutually respectively by magnet and shell inner top surface and base inner surface.When coil has audio signal to input, coil produces alternating magnetic field, giant magnetostrictive rod is alternately flexible by magnetic field alternative frequency, the conduct vibrations of this flexible generation is shaken on support to leading of base, leading in plane that kinetic energy is delivered to the hard objects contacted with it by the support that shakes causes vibration two to sound, the unreasonable structure of existing resonance speaker, its base is a fixing entirety with leading the support that shakes, like this in the process of vibration, lead when the support that shakes moves up and down and will overcome larger resistance, therefore the conversion efficiency of electroacoustic is lower, sound is little, low frequency is not enough, in addition, easily noise is produced in the process of vibration, its integral sound effect is bad.
[summary of the invention]
The object of the present invention is to provide a kind of can effectively overcome above-mentioned deficiency, sound is high, low frequency is abundanter, disc type spring resonance sound generator that the conversion efficiency of electroacoustic is high.
Technical scheme of the present invention is achieved in that it comprises shell, base, magnet, wound coil, described shell is connected by securing member with base, magnet and wound coil are arranged at shell inner cavity, its improvement is: be provided with below described base one can move up and down relative to base first lead vibration body, enclosure be provided with one can move up and down relative to shell second lead vibration body, on base, center is provided with an opening, first leads vibration body and second leads vibration body and is connected through the securing member of opening by one, described first leads in vibration body and is connected with a loop sleeve, wound coil is arranged in loop sleeve, described magnet is installed in loop sleeve, magnet is arranged with magnetic conductor, in base, first leads between vibration body and base and base outer second is led between vibration body and base and is equipped with video disc spring,
In said structure, the opening part surrounding on described base is equidistantly provided with four card columns, and the described second video disc Spring Card of leading between vibration body and base is located in the region that four card columns surround;
In said structure, described second leads vibration body is provided with rubber cushion;
In said structure, described base is provided with acoustic hole;
In said structure, described shell is that metal material is made.
Compared to the resonance speaker in technology, beneficial effect of the present invention is: be provided with below one, resonance speaker base of the present invention one can move up and down relative to base first lead vibration body, enclosure be provided with one can move up and down relative to shell second lead vibration body, in base, first leads between vibration body and base and base outer second is led between vibration body and base and is equipped with video disc spring, so, reduce the resistance of vibration, be conducive to leading vibration body and move up and down, the transformation efficiency of electroacoustic is higher; Opening part surrounding two, on base is equidistantly provided with four card columns, the described second video disc Spring Card of leading between vibration body and base is located in the region that four card columns surround, when can make to lead vibration body up-down vibration, remain on vertical direction and be unlikely to depart from, meanwhile, the resistance of leading vibration body vibration is further reduced; Three, second lead vibration body and be provided with rubber cushion, this design effectively can prevent from leading the noise that vibration body vibration produces; The acoustic hole four, base arranged, can make the better effects if of sound equipment, sound is larger; In addition, its shell is the interference of metal shell, maskable external electromagnetic field, strengthens the effect of sound equipment.
[accompanying drawing explanation]
Fig. 1 is decomposing schematic representation of the present invention;
Fig. 2 is the structural representation of this practicality;
In figure: 1, shell 2, base 3, magnet 4, wound coil 5, first are led vibration body 6, second and led vibration body 7, opening 8, loop sleeve 9, magnetic conductor 10, video disc spring 11, card column 12, rubber cushion 13, acoustic hole.
[embodiment]
Below in conjunction with drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2, the present invention is a kind of disc type spring resonance sound generator, it comprises shell 1, base 2, magnet 3, wound coil 4, shell 1 is connected by securing member with base 2, magnet 3 and wound coil 4 are arranged at shell 1 inner chamber, be provided with below base 2 one can move up and down relative to base 2 first lead vibration body 5, shell 1 inside be provided with one can move up and down relative to shell 1 second lead vibration body 6, first leads axis and the magnet 3 that vibration body 5 and second leads vibration body 6, the dead in line of wound coil 4, on base 2, center is provided with an opening 7, first leads vibration body 5 and second leads vibration body 6 and is connected through the securing member of opening 7 by one, lead in vibration body 5 first and be connected with a loop sleeve 8, wound coil 4 is arranged in loop sleeve 8, magnet 3 is installed in loop sleeve 8, magnet 3 is arranged with magnetic conductor 9, to produce stronger magnetic field, in base 2, first leads between vibration body 5 and base 2 and base 2 outer second is led between vibration body 6 and base 2 and is equipped with video disc spring 10, be conducive to first and lead vibration body 5, second leads vibration body 6 moves up and down, larger amplitude and larger sound effect can be produced, opening 7 place surrounding on base 2 is equidistantly provided with four card columns 11, the second video disc spring 10 of leading between vibration body 6 and base 2 is arranged in the region that four card columns 11 surround, first can be made to lead vibration body 5, second when leading vibration body 6 up-down vibration, remain on vertical direction and be unlikely to depart from, further reduce the resistance of vibration.
