Specific implementation mode
In order to illustrate more clearly of the present invention, the present invention is done further with reference to preferred embodiments and drawings
It is bright.Similar component is indicated with identical reference numeral in attached drawing.It will be appreciated by those skilled in the art that institute is specific below
The content of description is illustrative and be not restrictive, and should not be limited the scope of the invention with this.
As shown in Figure 1, the vibrational system 300 of one embodiment of the present of invention, which includes vibrating diaphragm 10 and combination, is fixed on vibrating diaphragm
The voice coil 20 on 10 surfaces, vibrating diaphragm 10 include the vibrating diaphragm reinforcement part that 11 surface of vibrating diaphragm body part is fixed in vibrating diaphragm body part 11 and combination
12, voice coil 20 includes the voice coil ontology 21 of annular and the lead 22 from the extraction of the same side of voice coil ontology 21, and lead 22 is outstanding
A pair of sky setting.Voice coil ontology 21 include positioned at 22 extraction location of lead outlet side 23 and it is opposite with outlet side 23 from
By side 24, since outlet side 23 and the quality of free side 24 are not completely equivalent, the amplitude of the larger outlet side 23 of quality is smaller, matter
The amplitude for measuring smaller free side 24 is larger, and the imbalance of amplitude can make vibrational system polarization problem occur.Therefore the present invention
The area that vibrating diaphragm reinforcement part 12 corresponds to the part of outlet side is less than the area for corresponding to free side, i.e. vibrating diaphragm reinforcement part 12 corresponds to
It is less than the quality corresponding to free side in the quality of outlet side 23, the barycenter of vibrational system is adjusted by vibrating diaphragm reinforcement part 12, is made
The barycenter of vibrational system is deviated to the centre of oscillation, can be reduced and be polarized caused by the Mass Distribution of vibrational system is unbalanced
Phenomenon, so as to improve the acoustic mass of loud speaker.
In the present embodiment, vibrating diaphragm reinforcement part 12 is set as from outlet side 23 to the gradual increased shape of the area of free side 24
Shape.Specifically, vibrating diaphragm reinforcement part 12 is set as trapezoidal shape, trapezoidal short side corresponds to outlet side 23, and trapezoidal long side corresponds to
In free side 24, two trapezoidal waists are set as being recessed inwardly arc-shaped.Using the vibrating diaphragm reinforcement part 12 of above-mentioned shape so that shaking
Film 10 corresponds to quality of the quality less than free side 24 of outlet side 23, balances the quality of lead 22, finally so that vibration system
The barycenter of system is deviated to the centre of oscillation, reduces the polarization phenomena caused by Mass Distribution unevenness.The shape of vibrating diaphragm reinforcement part 12
Can be trapezoidal can also be triangle, and those skilled in the art can according to actual needs become trapezoidal or triangle
Shape makes the barycenter of vibrational system be overlapped as possible with the centre of oscillation, and reduction polarizes caused by mass unbalance.
Further, vibrating diaphragm body part 11 includes sequentially connected central part 13, ring portion 14 and fixed part from inside to outside
15,20 secure bond of voice coil is in the lower surface of central part 13, and 12 secure bond of vibrating diaphragm reinforcement part is in the upper surface of central part 13.
Central part 13, which is located on the outer surface of vibrating diaphragm reinforcement part 12, is provided with reinforcing rib 16.In capable of being improved due to vibrating diaphragm reinforcement part 12
The rigidity of center portion 13, not by the region (position for mainly corresponding to outlet side) that vibrating diaphragm reinforcement part 12 is covered, by setting
Reinforcing rib 16 is set to improve rigidity.Specifically, reinforcing rib 16 is arranged on the outside of two waists of the vibrating diaphragm reinforcement part 12 of trapezoidal shape, often
3 reinforcing ribs are arranged in side, and the reinforcing rib per side dissipates towards trapezoidal center and is arranged.Reinforcing rib 16 from 13 surface of central part to
Upper bending protrusion or recess formation downwards in actual production can be when suppressing vibrating diaphragm, while suppressing and adding on central part 13
Strengthening tendons 16.The reinforcing rib 16 of present embodiment is upwardly away from voice coil direction and convexes to form, and the cross sectional shape of reinforcing rib 16 can be
Rectangle, triangle or semicircle.
Based on above-mentioned design, the present invention also provides a kind of loud speaker, one embodiment as shown in Figure 2, the loud speaker packet
Include vibrational system 300 and magnetic circuit system 400.Magnetic circuit system includes conductive magnetic yoke 43, secure bond in the magnetic of 43 upper surface of conductive magnetic yoke
Iron 42 and the washer 41 for being incorporated into magnet upper surface, form magnetic field, specifically between conductive magnetic yoke 43, magnet 42 and washer 41
, form magnetic gap between the side wall and magnet 42 of conductive magnetic yoke 43.Voice coil 20 is suspended in the magnetic gap, and voice coil 20, which is equipped with, to be drawn
Line 22, lead 22 are a pair being vacantly arranged.Wherein, on lead 22 can with connection terminal, by terminal voice coil 20 can with it is outer
Portion's circuit connection.When the audio signal of external circuit is by voice coil 20, the voice coil 20 of energization is in magnetic field internal vibration, the sound of vibration
