Abstract
The invention discloses a novel vibrating board for loudspeakers. The vibrating board is arranged in a basket of an audio device, consists of a thin board corresponding to caliber of a central basket, and is characterized in that the thin board consists of an inner circular ring which is arranged in the middle, an outer ring arranged outside and a plurality of connection ribs which connect the inner circular ring and the outer ring and are symmetrically arranged, and an inner edge of the inner circular ring is toothed. Thickness of the thin board is 1-5mm. Surface of the thin board is elliptical or circular, and made of textiles and matting by textile weaving such as NOMEX (meta-position aromatic polyamides), Aromatic polyamide (aramid fiber), polyester or cotton yarn and the like. The vibrating board has the advantages of simple structure, low production cost, good acoustic effect and the like.
Description
Technical field
The present invention relates to loudspeaker accessory field, more particularly relate to a kind of to there is simple, the effective diaphragm for speaker of structure.
Background technology
At present, the structure of loud speaker mainly comprises magnet base, voice coil loudspeaker voice coil, frame, drum paper, vibrational system, vibrational system is arranged between frame and cone, play the effects 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, by the oscillating plate between frame voice coil loudspeaker voice coil and outstanding limit Structure composing, existing oscillating plate is generally adopt wave-type vibration plate (namely playing ripple), its radial section undulate, employing fibrous cloth is made, as cotton yarn, the dimity, the materials such as nylon, and install in the limited product of sound space at TV etc., tonequality is wayward, in vibration, due to the wave structure of oscillating plate, and above bullet ripple, be often provided with two or more wire, it is occupied that ripple raises angle, Oscillation Amplitude is limited, cause on bass plentiful not soft, and the narrow limit of ellipse corrugated sheet both sides, audio frequency shake the effect of vibration of ripple uneven time also easily produce different sound.If application number is 200420008907.4, the applying date is on 03 29th, 2004, patent name is, the elastic wave sheet of loud speaker, this elastic wave sheet is that a level is installed in speaker frame, connect the pliability lamellar body of voice coil loudspeaker voice coil and oscillating plate, this elastic wave sheet have one outside coated with resin and form the wavy circular lamellar body of more than one concentric circles, its central authorities form the corresponding endoporus connecting voice coil loudspeaker voice coil and oscillating plate neck, the lamellar body of this bullet ripple plate is fitted with two wires, this two wire extends to endoporus from lamellar body outer radial, and bends along the wavy surface on lamellar body.This elastic wave sheet mainly makes two outer radial that its lamellar body fits extend to endoporus and the bending wire of fiber cloth wavy surface, wire one end is made to connect oscillating plate in loud speaker nearby, the other end is as the use of external signal connection, wire can be made to avoid pullling and coming off of vibrated plate violent oscillatory motion, thus be more suitable for practicality.This patent adopts wavelike structure face, just there are the problems referred to above.
Summary of the invention
Object of the present invention is exactly the deficiency in order to solve prior art, and a kind of structure provided is simple, the Novel vibrating board for loudspeaker that cost is low, acoustical quality is good.
The present invention adopts following technical solution to realize above-mentioned purpose:
This Novel vibrating board for loudspeaker, be arranged in the frame of sound equipment, be made up of the thin plate adapted with center basin bore, it is characterized in that: this thin plate by be arranged on annulus in centre, outside outer shroud and in connecting annulus and outer shroud and the some dowels be symmetrical set form, interior annulus inward flange is zigzag.
The thickness of described the thin plate is 1 ~ 5mm.
Described the thin plate surface is ellipse or circle, and its material is that NOMEX (a position Nomex) or Aromatic polyamide (aramid fiber) or the textile such as POLYESTER (polyester) or cotton yarn and material weave knitting.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, this Novel vibrating board for loudspeaker abandons existing ripple struction, adopt planarized structure, structure is very simple, in vibration processes, owing to adopting the texture structure of plane symmetry, do not have the ripple elevation angle suppressed, bass effect is plentiful soft, audio frequency shake the effect of vibration of ripple uneven time can not produce different sound, effectively adjust loudspeaker performance, vibration reliability is stronger, life-saving.
2, adopt plane texture structure, pericentral Oscillation Amplitude is larger, can break through the range demand that conventional loudspeakers does not reach.
3, the present invention can adopt the textile such as cotton yarn, aramid fiber and new material to make, and the convenient actual different needs that use adjust, and have good market value.
4, this speaker diaphragm neat appearance, thickness is thin, novel unique, produces assembling simply, can meet the demand of the ultra-thin market demand of available liquid crystal 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, be arranged in the frame 2 of sound equipment, be made up of the oval the thin plate 1 adapted with center basin bore, according to amplitude and acoustical design needs, this thin plate comprises interior annulus and outer toroid and symmetry two curve dowels being connected annulus therebetween of middle setting, in center, annulus inward flange is zigzag, oscillating plate is arranged on frame bosom recess, facilitates vibrating reed to fix.The thickness of described the thin plate 1 is 2mm, and its material is NOMEX (a position Nomex).The center circle of this slim oscillating plate and frame 2 centre bore concentric, oscillating plate is fixed in frame 2 by glue, can install the cone 3 adapted with frame 2 above oscillating plate.During use, when loud speaker passes into an audio electrical signal, voice coil loudspeaker voice coil will be subject to the size direction that is directly proportional to tone currents to be changed with tone currents and the power that changes, thus produces audio frequency vibration, drive the cone 3 in frame 2 to vibrate, make surrounding air send 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 embodiment 1 basis, two symmetrical dowels are increased in ring, namely the thin plate 1 comprises the interior annulus and peripheral elliptical ring and four symmetrical curve dowels therebetween that are arranged on centre, central circular inner edge is zigzag.
Embodiment 3
As shown in Figure 5, according to actual needs, Novel vibrating board for loudspeaker of the present invention, its thin plate 1 can also be designed to the structure of symmetrically arranged four dowels of equal circumference in outer shroud, plate body level is fixedly mounted in speaker frame.
Experiment proves, in the above-described embodiments, because inner circle edge have employed laciniation, convenient fixing oscillating plate, add that slab construction makes effect of vibration more balanced, the tonequality shown is more plentiful soft, and low tonequality performance is more outstanding.
Described slim oscillating plate plate can also be circular slab in addition, its material is that Aromaticpolyamide (aramid fiber) or the relevant textile such as POLYESTER (polyester) or cotton yarn and material are weaved knitting and be all included in scope, and oscillating plate material has some holes.
In above-described embodiment, oscillating plate annulus size and middle dowel lines can be arranged according to reality adjustment; Therefore, according to the equivalent variations that the present patent application the scope of the claims is done, under the prerequisite not departing from spirit of the present invention, the scope that the present invention is contained still is belonged to.
