Description
Technical field
The present invention relates to a kind of panel speaker, particularly a kind of double folding ring panel speaker.
Background technology
Along with the development of panel TV sets such as LCD, PDP and popularize, supporting with it loud speaker must update, conventional loudspeakers is generally band centring disk structure at present, centring disk and voice coil loudspeaker voice coil are bonding, the dull and stereotyped sound basin of voice coil loudspeaker voice coil and single ring is bonding, centring disk makes 2 centering of voice coil loudspeaker voice coil with ring as two springs, does not swing during vibration; Or the dull and stereotyped sound basin of single ring adds magnetic liquid structure with magnetic circuit, and ring makes centering of voice coil loudspeaker voice coil, adds magnetic liquid in the magnetic circuit, makes the voice coil loudspeaker voice coil other end centering of inserting belt coil in the magnetic circuit, and voice coil loudspeaker voice coil does not swing when vibrating.The structure of band centring disk must be reserved the space that a sheet swings up and down, and this has caused the loud speaker height to increase, and can't accomplish ultra-thin purpose; The structure of band magnetic liquid, because magnetic fluidity energy temperature influence is very big, voice coil temperature can raise during speaker operation, causes the magnetic fluidity to lose efficacy or to reduce easily, causes the instability of speaker operation.Now required loud speaker should have that thickness is ultra-thin, can reset good bass and middle pitch, can reach the requirement of full range band, and this is the structural design of needs breakthrough conventional loudspeakers just.
Summary of the invention
In view of the deficiency that prior art exists, the present invention brings acoustical quality poor for solving present like product because of the attenuation of loud speaker thickness, and stability is not high, and power bears low problem, designs a kind of double folding ring panel speaker especially.By having adopted the vibrational system design of double folding ring plate diaphragm; Adopt not with the design of centring disk or magnetic liquid, reached ultra-thin structure, acoustical quality is good, the effect that stability is high.
The present invention for achieving the above object, the technical scheme of being taked is: a kind of double folding ring panel speaker, comprise plate diaphragm, ring, voice coil loudspeaker voice coil, cast the basin frame that is connected together and rivets the wiring skeleton with magnetic conductor bowl, also comprise the magnet that is bonded in successively in the magnetic conductor bowl from bottom to top, washer, it is characterized in that: also comprise ring washer, described ring is by last ring, following ring constitutes, the described bulge loop of ring down faces down, the upper surface of the interior plane of a loop of following ring and the lower surface bonds of plate diaphragm are fixed, the lower surface of the outer plane of a loop of following ring and basin frame upper surface are adhesively fixed, the upper end of described voice coil loudspeaker voice coil and the lower surface bonds of plate diaphragm are fixed, the following anchor ring of described ring washer is adhesively fixed with the outer shroud planar upper surface of following ring, the described bulge loop of going up ring faces down, the lower surface of the interior plane of a loop of last ring and the upper surface of plate diaphragm are adhesively fixed, and the lower surface of the outer plane of a loop of last ring and the upper ring surface of ring washer are adhesively fixed.
The beneficial effect that the present invention produced is: the design reduces the loud speaker height, and power bearing ability is big, and the low frequency dive is dark, stablizing effect is good, in like product, it is good to have a bass effect, characteristics such as technology difficulty is little, in light weight, thin thickness, gamut tonequality are good.Particularly full range tonequality playback is preferably arranged for ultrathin type.These series of products suit to be placed on the radiation forward or backward of TV both sides and use, and the audio amplifier that can use separately or arrange in pairs or groups uses to realize the gamut playback, can be used for ultrathin colour TVs such as LCD, PDP.Thereby satisfy the market demand high-quality to loud speaker.

Embodiment
As Fig. 1, shown in 2, the double folding ring panel speaker, comprise magnetic circuit system, vibrational system and auxiliary system, vibrational system comprises plate diaphragm 1, last ring 2, ring washer 3, following ring 4 and voice coil loudspeaker voice coil 5, magnetic circuit system comprises magnet 7, washer 8 magnetic conductor bowls 9, auxiliary system comprises basin frame 10 and patch bay 6, magnetic conductor bowl 9 casts from the basin frame 10, wiring skeleton 6 is riveted on basin frame 10 bottom surfaces, bonded magnet 7 successively from bottom to top in magnetic conductor bowl 9, washer 8, magnet 7 is bonded in the center in the magnetic conductor bowl 9, voice coil loudspeaker voice coil 5 is adhered to vibrating diaphragm 1 lower surface center, the bulge loop face 4-of following ring 4) down, the lower surface bonds of the upper surface of the interior plane of a loop of following ring 4 and plate diaphragm 1 is fixed, the lower surface of the outer plane of a loop of following ring 4 and basin frame 10 upper surfaces are adhesively fixed, the lower surface bonds of the upper end of voice coil loudspeaker voice coil 5 and plate diaphragm 1 is fixed, the following anchor ring of ring washer 3 is adhesively fixed with the outer shroud planar upper surface of following ring 4, the bulge loop face 2-of last ring 2) down, the upper surface of the lower surface of the interior plane of a loop of last ring 2 and plate diaphragm 1 is adhesively fixed, the upper ring surface of the lower surface of the outer plane of a loop of last ring 2 and ring washer 3 is adhesively fixed, and voice coil loudspeaker voice coil 5 is suspended in the magnetic circuit system by the support of last ring 2 and following ring 4.
