The vibrational structure includes being located on the voice coil 5 of the newel 11 and is connected to described 11 one end of newel
Sound film 6.
The utility model has the technical effect that relative to the prior art：The utility model is by the way that 1 newel 11 of T iron is set
To be round table-like, and the newel 11 is set with the socket of magnet 2, in the case where magnetic flux is identical, is reduced magnetic circuit gap, is led
Magnetic function is stronger, and magnetic induction intensity increase, the setting of first through hole 10 enhances heat dissipation, increases power of loudspeaker, improve
The sound quality of high pitch not only meets requirement of the consumers in general to high-power high sound press, also meets the requirement to sound quality.
Fig. 5 is please referred to, the cover 41 is preferably arranged to hemispherical, the inner cavity of the first through hole 10 of top central dip
Areflexia closed chamber is constituted with the bowl chamber with the cover 41, the height of the point centrum 42 is less than the T iron 1 and the cover
The sum of 41 axial height, the sound wave that this structure enables to sound film 6 to be radiated in first through hole 10 are guided and fade away,
It ensure that the pure tone-off dye of high pitch.Preferably, the cover is integrally formed with the sharp centrum.
T iron 1 is also electrician's iron, its quality is pure iron.In voice unit (VU), the main function of T iron 1 is exactly to be powered
In the case of magnetic conduction, but it does not have remanent magnetism.Magnetic field disappears after loud speaker power-off, its magnetism also disappears immediately.
Preferably, the magnet 2 is 2 oxysome of high-performance permanent, and when larger magnetic force big for loud speaker volume provides
Powerful driving force and control force effectively prevents the transient distortion that control force deficiency generates during Larger Dynamic.The magnet 2 is preferred
A diameter of 70mm is highly 15mm.
The first through hole 10 can be the consistent cylindrical hole in aperture, it is preferable that the aperture of the first through hole 10
Along the T heads 12 to the tapered setting in 11 direction of newel, it is more advantageous to further enhancing magnetic conduction function in this way, improves high pitch
Sound quality.
It please refers to Fig.1, Fig. 2 and Fig. 5, specifically, the vibrational structure further includes eqalizing cricuit 6, and the center of the sound film 6 is opened

50 are connected with the phase plug 71.The guided wave cone of the eqalizing cricuit 6 is bullet-headed, and the guided wave cone can help sound field natural
Diffusion overcomes the problem of traditional spheroidal guided wave cone high pitch is susceptible to distortion, focusing and sound wave reverse phase.The phase plug 71 is in
Starlike setting can not influence the transmission of sound while fixation eqalizing cricuit 6.
Fig. 5 is please referred to, specifically, the vibrational structure further includes the copper sheathing 51 for being located on the newel 11, the sound
Circle 5 is located on the copper sheathing 51.The copper sheathing 51 coordinates the newel 11 so that high frequency is smoother, and extension is broader.
It please refers to Fig.1 and Fig. 2, specifically, the voice coil 5 is equipped with spaced venthole, to balance interior outer gas
Pressure difference releases energy, and power is born so as to promote loud speaker.Preferably, the venthole for 9 and is set so that interior at equal intervals
Outer draught head is in optimum balance state.The voice coil 5 uses heat-resisting aluminum pipe and copper-clad aluminum conductor, and copper-clad aluminum conductor is than copper wire efficiency more
Height, quality is lighter, and 5 material of voice coil can be worth high frequency accordingly to increase, so as to increase the resonance cycle of high range.
It please refers to Fig.1 to Fig. 5, specifically, the sound film 6 is concentric circles double diaphragm, i.e., the vibrating diaphragm of concentric dual damascene shape, this
The sound film 6 of structure vibrates area bigger, treble audio and middle low frequency stereovision compared to top dome shape sound film 6 universal on the market
Stronger, sound is more mellow and fuller, and frequency response is broader.The sound film 6 is using foaming cloth material, and quality is lighter, and intensity is more preferable, sound-absorbing and every
Hot property enhances, and high pitch is clear and legible, realizes accurate distortionless high pitch effect, and the high pitch upper limit breaches the pole of common high pitch
Limit, reaches 40KHz.
Fig. 5 is please referred to, specifically, the loud speaker further includes to fix the branch that the sound film 6 is connected with the washer 3
Frame 8, the stent 8 offer third through-hole, and the sound film 6 is connected at the third through-hole, and the stent 8 includes opposite match
It closes the first support 81 being fixedly connected and second support 82, the washer 3 is fixed on the first support 81 and described second
Between frame 82.The stent 8 is plastic cement material, unlikely when fixing the sound film 6 with the washer 3 in this way to cause to wear.
It please refers to Fig.1, Fig. 2 and Fig. 5, specifically, the loud speaker further includes the panel 9 for being connected to the stent 8, described
Panel 9 offers the fourth hole 90 for exposing sound film 6.The panel 9 is used to that the loadspeaker structure to be protected not ground
It damages or collides with, and so that the loud speaker shape is more beautiful.
It please refers to Fig.1, Fig. 2 and Fig. 5, specifically, the panel 9 includes the fixed plate 92 being fixedly connected with the stent 8
And the lamina rara externa 91 with the fixed plate 92 clamping.The fixed plate 92 is connected by screw with the stent 8, the fixation
Plate 92 is equipped with snap ring towards 91 side of lamina rara externa, and the lamina rara externa 91 is equipped with and the card towards 92 side of fixed plate
The buckle of ring cooperation clamping, the screw in fixed plate 92 described in this way can be covered and hidden, appearance by the lamina rara externa 91
With more aesthetic feeling.
