Abstract
The present invention provides a location supporting plate of the loudspeaker, also named as a center suspension or an elasticity wave, in particular a thin loudspeaker location supporting plate structure. According to the design of the invention, the section of the location supporting plate shows a wave shape, a center hole is mounted in the center of the location supporting plate, each wave comprises a wave trough and a peak respectively, and the height of the peak is higher than the height of the wave; a projecting platform is composed of one peak, or two more peaks having similar or same heights; the projecting platform at least has two; and height of the projecting platform near the center is higher than the heights of the rest projecting platforms. The location supporting plate of the loudspeaker employs a multiple projecting platforms structure, especially fit for audio pattern design of plate video devices such as LCD, PDP and the like. The invention improves the compliance of the location supporting plate or the whole loudspeaker vibration system, thereby effectively reducing the resonant frequency of the loudspeaker, improving the low frequency response.
Description
Technical field
The present invention relates to loudspeaker positioning support chip, be centring disk again or play ripple, specifically a kind of orientation sheet-supporting structure of thin type speaker that is applicable to that high-power full frequency band loud speaker is used.
Background technology
Be applied to the high-power full frequency band loud speaker of plate video equipments such as LCD, PDP now,, generally can adopt more flat speaker frame and sound basin in order to make whole loudspeaker unit structure thinner.But traditional locating branch slice connects basin frame and sound basin, owing in speaker operation, can cause the edge of sound basin and locating branch slice to collide to a certain degree down in that the sound basin is flat, and the normal sounding of obstruction loud speaker.Therefore, have only a kind of novel orientation sheet-supporting structure of design, it is big with the power of loud speaker just to meet dull and stereotyped video equipment, the requirement that structure is thin.
Summary of the invention
The object of the present invention is to provide a kind of slim high-power full frequency band loud speaker locating branch slice, this loudspeaker positioning support chip adopts many boss structures, is specially adapted to the audio scheme design of plate video equipments such as LCD, PDP.Owing to improved the locating branch slice compliance of whole speaker vibration system in other words, thereby reduced the resonance frequency of loud speaker effectively, improved LF-response.
According to design provided by the present invention, the section of locating branch slice is wavy, at the center of locating branch slice centre bore is set, and each wave comprises a trough and a crest respectively, and the height of described crest is higher than the height of wave; A crest, or highly close or equal two or more crests constitute a boss; Described boss has two at least; And the height of the boss at close center is higher than the height of all the other boss.
The height of described crest is meant the distance of the bottom surface of locating branch slice to the upper surface of crest; The height of described boss is meant the distance of the bottom surface of locating branch slice to the upper surface of corresponding crest.
Described locating branch slice is rounded, and described centre bore is positioned at the central authorities of circular locating branch slice.The height of the crest of the central authorities of close locating branch slice is higher than the height near the crest at the edge of locating branch slice.The edge of described locating branch slice is an annular plate.
Described crest has n, positioned adjacent to prop up the primary peak at edge of sheet and the height of secondary peak equates that the first corresponding trough and the height of second trough also equate; N the crest of contiguous centre bore and the height of n-1 crest equate; And, n crest, or the height of n crest and n-1 crest is higher than the height of all the other crests respectively, and the height of n-1 trough also is higher than the height of all the other troughs.The height of described trough refers to from the bottom surface of locating branch slice to the distance of the lower surface of trough.
Use the loud speaker of the locating branch slice of boss structure more than this kind, in the time of can avoiding the sound basin to make anti-phase motion downwards effectively, sound basin bottom part and locating branch slice collide.Simultaneously, owing to increased a plurality of boss, make the shift length of locating branch slice increase, greatly improved locating branch slice, the compliance of whole speaker vibration system has in other words reduced the resonance frequency of loud speaker effectively, improves LF-response.This is to extremely helpful with slim high-power full frequency band speaker design.
Description of drawings
Fig. 1 is a sectional schematic diagram of the present invention.
Fig. 1 is a section three-dimensional map of the present invention.
Embodiment
Shown in Figure 1 is a kind of 4 crests that have only, and forms the structure of two boss, can also be designed to the structure greater than two boss certainly as requested.
As shown in the figure: it is wavy locating branch slice 9 that a section is arranged, ring plate 7 based on the edge, the upper surface of ring plate 7 is inclined upwardly to extend and arches upward, form primary peak 3, the diagonally extending that faces down of primary peak 3 forms first trough 4, the face of first trough 4 extends upward and forms secondary peak 3 ' again, secondary peak 3 ' downward-sloping second trough 4 ' that extends to form; So repeatedly, can form several crests and trough.What primary peak 3 and secondary peak 3 ' formed first boss, 1, the second trough 4 ' extends projection towards tilting, and forms facing down of the 3rd crest 5, the three crests 5 and extends to form the 3rd trough 6, the three troughs 6 and be inclined upwardly to extend and form the 4th crest 5 ' again; So repeatedly, can form several new crest and troughs.The 3rd crest 5 and the 4th crest 5 ' form the downward-sloping slightly extension of second boss, 2, the four crests 5 ', form a slightly a bit summit of the locating branch slice 9 of depression, and the central authorities on the summit offer centre bore 8.
The shape of described crest and trough and quantity can design voluntarily according to the performance of loud speaker.But, bottom surface with edge 7 is a benchmark, boss 2 must be higher than boss 1, therefore, formed the 3rd crest 5 and the 4th crest 5 ' and the 3rd trough 6 on boss 2 must be higher than formed primary peak 3 and secondary peak 3 ' and first trough 4 and second trough 4 ' on boss 1, have only boss 2 to be higher than boss 1, when could guarantee speaker operation, the sound basin can not collide locating branch slice 9, particularly collides the primary peak 3 and secondary peak 3 ' of boss 1 and formation boss 1.In addition, the shape of boss and quantity also can design voluntarily according to the performance of loud speaker, but must guarantee the ring plate 7 from the edge, and the closer to centre bore 8, the height of boss is high more.
The height of described trough refers to that from the bottom surface of locating branch slice 9 to the distance of the lower surface of trough, the height of described crest is meant the distance of the bottom surface of locating branch slice 9 to the upper surface of crest.The height of described boss is meant the distance of the bottom surface of locating branch slice 9 to the upper surface of corresponding crest.Described close height is meant that when actual production is made that can not do both height truly equates, always therefore some difference be referred to as this situation about there are differences close.
