Description
Technical field
The present invention relates to loudspeaker accessory field, has simple in construction, effect is good to raise more particularly to a kind of
Sound device oscillating plate.
Background technology
At present, the structure of loudspeaker mainly includes magnet base, voice coil loudspeaker voice coil, frame, drum paper, vibrational system, and vibrational system is set
Put between frame and cone, play the effect such as traction drum paper directional vibration, express drum paper self character tonequality, also allow voice coil loudspeaker voice coil not
Have and wave phenomenon, keep ordinary life, be made up of the oscillating plate between frame voice coil loudspeaker voice coil and outstanding side structure, existing oscillating plate one
As be to use wave-type vibration plate (playing ripple), its radial direction section undulate, be made of fibrous cloth, such as cotton yarn, the dimity, Buddhist nun
The materials such as dragon, and in the limited product of the installation sound space such as TV, tonequality is difficult to control, in vibration, due to oscillating plate
Wave structure, and play and be often provided with two or more wire above ripple, ripple raises that angle is occupied, and Oscillation Amplitude is limited,
Not plentiful soft enough on bass, and the narrow side of ellipse corrugated sheet both sides is caused, in the effect of vibration inequality of audio vibration wave
It is also easy to produce abnormal sound.Such as Application No. 200420008907.4, the applying date is on 03 29th, 2004, and patent name is loudspeaker
Elastic wave sheet, the elastic wave sheet is that a level is installed in speaker frame, connects the pliability lamellar body of voice coil loudspeaker voice coil and oscillating plate, the bullet
Wave plate has an outside coated with resin and forms the more than one wavy circular lamellar body of concentric circles, and its center forms corresponding connect
The endoporus of voice coil loudspeaker voice coil and oscillating plate neck is connect, two wires are fitted with the lamellar body of the bullet ripple plate, two wire is from the outside of lamellar body
Endoporus is extended radially to, and is bent along the wavy surface on lamellar body.The elastic wave sheet mainly makes the outside of fitting two on its lamellar body
Endoporus and the wire of fiber cloth wavy surface bending are extended radially to, wire one end is connected the vibration in loudspeaker nearby
Plate, the other end are used as external signal connection, and wire can be made to avoid pullling and coming off for vibrated plate violent oscillatory motion, from
And it is more suitable for practicality.This patent uses wavelike structure face, there is above mentioned problem.
The content of the invention
The purpose of the present invention is exactly in order to solve the deficiency of prior art, and offer is a kind of simple in construction, and cost is low, sound
The good novel vibrating board for loudspeaker of matter effect.
The present invention is to realize above-mentioned purpose using following technical solution：
This novel vibrating board for loudspeaker, it is arranged in the frame of sound equipment, is made up of the thin plate being adapted with center basin bore,
It is characterized in that：The thin plate by be arranged on centre interior annular, outside outer shroud and connection interior annular and outer shroud and be in
Symmetrically arranged some dowel compositions, interior annular inward flange is zigzag.
The thickness of the thin plate is 1~5mm.
The slim plate surface is ellipse or circle, and its material is NOMEX (meta Nomex) or Aromatic
The textile such as polyamide (aramid fiber) or POLYESTER (polyester) or cotton yarn and material weaving knitting.
The beneficial effect that the present invention can be reached using above-mentioned technical solution is：
1st, this novel vibrating board for loudspeaker abandons existing ripple struction, and using planarized structure, structure is very simple, shakes
During dynamic, due to using the symmetrical texture structure of plane, it is suppressed without the ripple elevation angle, bass effect is plentiful soft, in audio
Abnormal sound will not be produced during the effect of vibration inequality of vibration wave, effectively adjusts loudspeaker performance, vibration reliability is stronger, extends the longevity
Life.
2nd, using plane texture structure, pericentral Oscillation Amplitude is bigger, can break through conventional loudspeakers and not reached
Range demand.
3rd, the present invention can use the textiles such as cotton yarn, aramid fiber and new material to be made, and convenient actual different use needs
It is adjusted, there is good market value.
4th, this speaker diaphragm neat appearance, thickness of thin, novel and unique, production assembling is simple, can meet available liquid crystal
The demand of the ultra-thin market demand of TV or Related product.

Description of reference numerals：The thin plate 1, frame 2, cone 3.
Embodiment
Embodiment 1 as shown in Figure 1, Figure 2, Figure 3 shows, novel vibrating board for loudspeaker of the present invention, is arranged on the frame 2 of sound equipment
It is interior, it is made up of the oval the thin plate 1 being adapted with center basin bore, according to amplitude and acoustical design needs, in the thin plate
Connect including the middle interior annular set and outer toroid and therebetween symmetrical two curve dowels of annulus, center interior annular
Inward flange is zigzag, and oscillating plate is arranged on frame bosom recess, facilitates vibrating reed to fix.The thickness of the thin plate 1
It is NOMEX (meta Nomex) to spend for 2mm, its material.The center circle of the slim oscillating plate and the centre bore concentric of frame 2,
Oscillating plate is fixed in frame 2 by glue, and the cone 3 being adapted with frame 2 can be installed above oscillating plate.In use,
When loudspeaker is passed through an audio electrical signal, voice coil loudspeaker voice coil will be by size direction directly proportional to tone currents with audio-frequency electric
Rheology and the power changed, so as to produce audio frequency vibration, drive the cone 3 in frame 2 to vibrate, surrounding air is sent sound wave.
Embodiment 2
As shown in figure 4, novel vibrating board for loudspeaker of the present invention, according to amplitude and acoustical design needs, on the basis of embodiment 1
On, increase by two symmetrical dowels in ring, i.e., include interior annular and peripheral elliptical ring and two for being arranged on centre in the thin plate 1
Four symmetrical curve dowels between person, central circular inner edge are zigzag.
Embodiment 3
As shown in figure 5, according to being actually needed, novel vibrating board for loudspeaker of the present invention, it is also designed in its thin plate 1 outer
The structure of symmetrically arranged four dowels of equal circumference, plate body level are fixedly mounted in speaker frame in ring.
It is demonstrated experimentally that in the above-described embodiments, it is convenient to fix oscillating plate because inner circle edge employs laciniation,
Make effect of vibration more balanced plus slab construction, the tonequality shown is more plentiful soft, and bass matter performance is more prominent.
The other slim oscillating plate plate can also be circular slab, its material for Aromaticpolyamide (aramid fiber) or
Related textile and material the weaving knitting such as person POLYESTER (polyester) or cotton yarn vibrates sheet material in the range of being all contained in
There are some holes in matter.
Oscillating plate annulus size and middle dowel lines can be set according to actual adjustment in above-described embodiment；Therefore according to this
The equivalent variations that patent application the scope of the claims is made, without departing from the spirit of the invention, still belonging to what the present invention was covered
Scope.
