Abstract
The utility model relates to a twin hull frequency speaker, which comprises a pot frame, a surface diaphragm, a speaker coil frame, a speaker coil and a centering support chip fixed with the speaker coil frame and a magnetizer comprising a concentrating flux plate at the bottom and a magnetic column which is convex at the centre of the concentrating flux plate at the back of the speaker, a plurality of arc-shaped slot holes are arranged in a space on the root circumference circling the magnetic column on the concentrating flux plate of the magnetizer, a second vocalism structure with same construct and connecting structure is positioned below the magnetizer. The two speakers are combined in a whole essentially, and the two speakers share with a magnetic circuit. The two sets of the vocalism structure produce vocalism vibration in the reverse direction, the forces produced by vibration is counteracted mutually, and the counterforce produced by the speaker is almost voided to the supporting object for the speaker. When the speaker is used in the mega woofer with three chambers and a mouth, the counterforce from the speaker to the sound box is nearly zero, then avoiding the sound box vibration which is caused by the counterforce from the speaker to the sound box to make the low sound more natural.
Description
Technical field
The utility model relates to loud speaker, is specially a kind of binary audio tweeter.
Background technology
When existing ordinary audio loud speaker is used for three chamber single radial cut sub-woofer, two ordinary audio loud speaker reversal of vibrations sounding in the audio amplifier.Each loud speaker puts on reaction force on the sound box in sounding, make sound box particularly fixedly the dividing plate of loud speaker also participate in vibration sounding, make the bass dulling of audio amplifier.Therefore, the structure of existing audio tweeter is not suitable for three chamber single radial cut sub-woofer especially.At present, solve the method for three chamber single radial cut sub-woofer bass dullings, be that the structure of sound box is improved, as between the dividing plate of fixing loud speaker, adding support, reduce the particularly vibration of casing internal partition of sound box as much as possible with this, like this, certainly will cause the loudspeaker box structure complexity.
Summary of the invention
The utility model solves the existing bigger problem of audio frequency loudhailer reaction force in vibration sounding, provides a kind of reaction force little even do not have a binary audio tweeter of reaction force.
The utility model is to adopt following technical scheme to realize: the binary audio tweeter, 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, be provided with below the magnetic conductor with magnetic conductor above the symmetry, also by the basin frame, the surperficial vibrating diaphragm that is connected with the basin frame, with the fixing sound ring frame of vibrating diaphragm, second vocal structure that constitutes with fixing voice coil loudspeaker voice coil of sound ring frame and centring disk, have on one end of the sound ring frame in second vocal structure with magnetic conductive board on the corresponding groove in position, non-arc-shaped slot place of conducting magnetic column root circumference, the end that sound ring frame in second vocal structure has groove passes the arc-shaped slot of being opened on the magnetic conductive board of magnetic conductor, and the voice coil loudspeaker voice coil in second vocal structure is fixed on the other end of sound ring frame.
The utility model comes down to set up a cover and constitutes the vocal structure (in other words exactly two loud speakers united two into one) all identical with syndeton on the basis of existing audio tweeter, the shared magnetic circuit system of two cover vocal structures (two loud speakers in other words).Two cover vocal structures produce the opposite sounding vibration of directions, and the active force that vibration produces is cancelled out each other, make loud speaker substantially not to support or fixedly the object of loud speaker produce reaction force.When this loud speaker is used for above-mentioned three chamber single radial cut sub-woofer, loud speaker is almost nil to the reaction force of audio amplifier, thereby avoid because of loud speaker to the casing vibration that the reaction force of audio amplifier causes, reduce or avoid casing to send extra sounds, make the bass of audio amplifier more solid, nature.The utility model novel structure, reasonable is specially adapted to three chamber single radial cut sub-woofer.

Embodiment
The binary audio tweeter, 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 6 around the conducting magnetic column root circle spacing have an arc-shaped slot 10, be provided with below the magnetic conductor with magnetic conductor above the symmetry, also by basin frame 11, with the fixing surperficial vibrating diaphragm 12 of basin frame, with the fixing sound ring frame 13 of vibrating diaphragm, second vocal structure that constitutes with fixing voice coil loudspeaker voice coil 14 of sound ring frame 13 and centring disk 15, have on one end of the sound ring frame 13 in second vocal structure with magnetic conductive board on the corresponding groove 16 in position, non-arc-shaped slot place of conducting magnetic column root circumference, the end that sound ring frame 13 in second vocal structure has groove passes the arc-shaped slot of being opened on the magnetic conductive board of magnetic conductor, and the voice coil loudspeaker voice coil 14 in second vocal structure is fixed on the other end of sound ring frame 13.Basin frame 1 is fixing with the magnetic conduction sheet 8 on magnet top, and the inwall of the other end of centring disk 5 and basin frame is fixed.Voice coil loudspeaker voice coil in the two cover vocal structures feeds electric signal simultaneously, behind excitation two voice coil loudspeaker voice coils (being coated within the magnetic field), can produce simultaneously according to music or sound rhythm toward the sound ring frame, centring disk and the vibrating diaphragm that cover motion and drive separately and produce vibration, the vibration by vibrating diaphragm sends out sound wave in the opposite direction.
Sound ring frame in two vocal structures all is placed on the conducting magnetic column, preferably that the opposed end of two sound ring frames is overlapping during assembling, and make voice coil loudspeaker voice coil be fixed in identical horizontal level (being positioned at the identical position of magnetic circuit in other words), like this, the symmetry that helps two cover vocal structures, the whole stress equalization of loud speaker.The voice coil loudspeaker voice coil coiling number of turn in the two cover vocal structures is identical, makes two vocal structures produce identical vibration, and in use makes the electric connection mode of two voice coil loudspeaker voice coils can guarantee that two vocal structures send vibration in the opposite direction.
Second vocal structure vibrating diaphragm middle part cementation has dust cover 17.
