Abstract
The utility model relates to a recoilless loudspeaker which comprises a basin stand, surface diaphragm, a voice coil frame, a voice coil and a centering support chip which are fixed with the voice coil, and a magnetic conductor which is arranged in the back part of the loudspeaker and is composed of a bottom magnetic conductive plate and a magnetic conductive post which is raised in the middle part of the magnetic conductive plate. Arced slotted holes are circumferentially arranged around the root part of the magnetic conductive post on the magnetic conductive plate of the magnetic conductor with intervals, and a loudspeaker sound vibration balance vibrating structure which is composed of the voice coil frame, the voice coil, the centering support chip and a vibrator is arranged under the magnetic conductor via the arced slotted holes. With adding a loudspeaker sound vibration balance vibrating structure on the basis of a traditional loudspeaker structure, the recoil generated when the loudspeaker vibrating and sounding can be counteracted, decreased even eliminated. The utility model has the advantages of reasonable and novel structure. The loudspeaker is fixed on a Loudspeaker panel, the utility model can effectively avoid sound box vibration caused by the recoil generated when the loudspeaker vibrating and sounding owing to no recoil, therefore, the utility model can increase the sound quality of the sound box.
Description
Technical field
The utility model relates to loud speaker, is specially a kind of recoilless loud speaker.
Background technology
Traditional loud speaker particularly woofer owing to directly be fixed on the Loudspeaker panel, in the time of its vibration sounding to audio amplifier particularly Loudspeaker panel produce kick (or claiming reaction force), make together vibration sounding of audio amplifier, thereby make audio amplifier sound become muddy, influence the particularly tonequality of high-quality speaker of audio amplifier.
Summary of the invention
The utility model solves existing loud speaker sounding, and kick is big and then influence the problem of audio amplifier tonequality simultaneously, and a kind of recoilless loud speaker is provided.
The utility model is to adopt following technical scheme to realize: recoilless loud speaker, comprise the basin frame, the surperficial vibrating diaphragm that is connected with the basin frame, with the fixing sound ring frame of vibrating diaphragm, with fixing voice coil loudspeaker voice coil and the centring disk of sound ring frame, be positioned at the magnetic conductor that the conducting magnetic column by bottom magnetic conductive board and magnetic conductive board middle part projection at loud speaker rear portion constitutes, with the fixing ringshaped magnet of magnetic conductor, the magnetic conduction sheet on ringshaped magnet top and the phase place awl of fixing with the conducting magnetic column on the magnetic conductor that is positioned at diaphragm of loudspeaker middle part, on the magnetic conductive board of magnetic conductor around the conducting magnetic column root circle spacing have an arc-shaped slot, below magnetic conductor, be provided with second sound ring frame, have on one end of second sound ring frame with magnetic conductive board on the corresponding groove in position, non-arc-shaped slot place of conducting magnetic column root circumference, one end of second sound ring frame passes the arc-shaped slot of being opened on the magnetic conductive board of magnetic conductor and be fixed with second voice coil loudspeaker voice coil on the other end, is fixed with second centring disk and balance vibrators at the end that has groove of second sound ring frame.The utility model is provided with the balance vibration structure of the loud speaker sounding vibration that is made of sound ring frame, voice coil loudspeaker voice coil, centring disk and oscillator on the architecture basics of conventional loudspeakers.The shared cover magnetic circuit of balance vibration structure and loud speaker vocal structure.The coiling number of turn of the original voice coil loudspeaker voice coil and second voice coil loudspeaker voice coil is identical, the electrical connection of two voice coil loudspeaker voice coils can guarantee that original vocal structure sends identical vibration simultaneously in the opposite direction with corresponding with it balance vibration structure during use, make the balance vibration structure offset the kick that the vibration of loud speaker sounding produces, weaken even eliminate the purpose of loud speaker the Loudspeaker panel kick thereby reach.
The utility model is by setting up the balance vibration structure of former sounding vibration on conventional loudspeakers, the kick to Loudspeaker panel that produces when making the loudspeaker vibration sounding is cancelled, thereby it is reduced even eliminates.It is rational in infrastructure, novel.This loud speaker is fixed in Loudspeaker panel, because it is recoilless, the audio amplifier that the kick in the time of can effectively avoiding because of the loudspeaker vibration sounding causes vibrates, thereby can improve the tonequality of audio amplifier.

Embodiment
Recoilless loud speaker, comprise basin frame 1, the surperficial vibrating diaphragm 2 that is connected with the basin frame, with the fixing sound ring frame 3 of vibrating diaphragm, with fixing voice coil loudspeaker voice coil 4 and the centring disk 5 of sound ring frame, be positioned at the magnetic conductor 6 that the conducting magnetic column by bottom magnetic conductive board and magnetic conductive board middle part projection at loud speaker rear portion constitutes, with the fixing ringshaped magnet 7 of magnetic conductor, the magnetic conduction sheet 8 on ringshaped magnet top and the phase place awl of fixing with the conducting magnetic column on the magnetic conductor 9 that is positioned at diaphragm of loudspeaker middle part, on the magnetic conductive board of magnetic conductor around the conducting magnetic column root circle spacing have an arc-shaped slot 10, below magnetic conductor, be provided with second sound ring frame 11, have on one end of second sound ring frame 11 with magnetic conductive board on the corresponding groove 12 in position, non-arc-shaped slot place of conducting magnetic column root circumference, one end of second sound ring frame 11 passes the arc-shaped slot of being opened on the magnetic conductive board of magnetic conductor, and on the other end, be fixed with second voice coil loudspeaker voice coil 13, be fixed with second centring disk 14 and balance vibrators 15 at the end that has groove of second sound ring frame.
The original sound ring frame and second sound ring frame all are placed on the conducting magnetic column, preferably that the opposed end of two sound ring frames is overlapping during assembling, and make two voice coil loudspeaker voice coils be fixed in identical horizontal level (being positioned at the identical position of magnetic circuit in other words), like this, the symmetry that helps loadspeaker structure helps eliminating more up hill and dale the kick that the vibration sounding of loud speaker produces.The structure of second centring disk and be connected and fixed identical with centring disk in the vocal structure.Oscillator quality in the balance vibration structure be complementary with the quality of vibration sounding structure (mainly being vibrating diaphragm, basin frame and the different mass discrepancies of bringing of two sound ring frame shapes).
