Embodiment
A kind of ultra-thin panel speaker is made up of plate diaphragm 1, ring 2, framework 3, centring disk 4, plastic pallet 5, voice coil loudspeaker voice coil 6, last magnet 7, magnetic conductive splint 8, lower magnet 9,10 of bottom enclosure; Plate diaphragm 1, ring 2, centring disk 4, plastic pallet 5, voice coil loudspeaker voice coil 6 constitute the vibrational system of said loud speaker; Last magnet 7, magnetic conductive splint 8, lower magnet 9 constitute the magnetic circuit system of said loud speaker; Plate diaphragm 1 and ring 2 bond together through bonding agent, and the lower surface of ring 2 is bonded in through bonding agent on the outer surface of cupular part of framework 3, forms the vibrating mass of loud speaker jointly; The lower surface of the upper surface of plastic pallet 5 and plate diaphragm 1 bonds together through bonding agent, and the top inner surface of the sidewall surfaces of plastic pallet 5 and voice coil loudspeaker voice coil 6 bonds together through bonding agent; The inner edge of centring disk 4 is adhesively fixed on the sidewall of voice coil loudspeaker voice coil 6, and the outer rim lower surface bonds of centring disk 4 is fixed on the bottom outer surface of framework 3; The lower sidewalls surface of voice coil loudspeaker voice coil 6 is wound with voice coil line, and is suspended among the gap of magnetic conductive splint 8 and bottom enclosure 10 formation the electromagnetic field that is used to change; All be integral between last magnet 7, magnetic conductive splint 8, the lower magnet 9, and be adhesively fixed on the bottom enclosure 10 through bonding agent is bonding; Be in the same place with bottom enclosure 10 fixed bondings in the bottom of framework 3.
The working method of the utility model is: plate diaphragm 1, ring 2, the framework 3 common vibrating mass that form loud speaker; The lower surface bonds of plastic pallet 5, plate diaphragm 1, the top inner surface of the sidewall surfaces of plastic pallet 5 and voice coil loudspeaker voice coil 6 is bonding, is used for moving both vertically of voice coil loudspeaker voice coil is delivered to plate diaphragm 1 surface; The inner edge of centring disk 4 is adhesively fixed on the sidewall of voice coil loudspeaker voice coil 6, and the outer rim lower surface bonds of centring disk 4 is fixed on the bottom outer surface of framework 3, is used to the centering that guarantees that voice coil loudspeaker voice coil 6 moves both vertically; The lower sidewalls surface of voice coil loudspeaker voice coil 6 is wound with voice coil line, and is suspended among the gap of magnetic conductive splint 8 and bottom enclosure 10 formation the electromagnetic field that is used to change; All be integral between last magnet 7, magnetic conductive splint 8, the lower magnet 9, and be adhesively fixed on the bottom enclosure 10, be used to produce required permanent magnetic field through bonding agent is bonding; Being in the same place with bottom enclosure 10 fixed bondings in the bottom of framework 3, forms the monolithic case of loud speaker.
The diaphragm structure form of conventional loudspeakers is generally the taper basin, can improve the rigidity of structure of vibrating diaphragm.The material of vibrating diaphragm selects the paper stock of different densities usually.Plate diaphragm 1 is circular slab construction, can reduce the integral thickness of loud speaker significantly.
The composite material that plate diaphragm 1 adopts cross section to have the honeycomb characteristic is processed; On the cross section of plate diaphragm 1; Inside is equally distributed honeycomb cavernous structure; Upper and lower surfaces then adopts macromolecule resin material to cover monoblock vibrating diaphragm surface, and the composite material of plate diaphragm is made up of the poroid acrylic resin of honeycomb, glass fiber, nanometer grade silica inorganic filler; Acrylic resin accounts for raw material weight than 75% ~ 90%; Glass fiber accounts for raw material weight than 5% ~ 10%, and the nanometer grade silica inorganic filler accounts for raw material weight than 5% ~ 15%; Because the inside of vibrating diaphragm is the honeycomb cavernous structure, so the solid material of the same size of density greatly reduces, and rigidity significantly improves.
In order further to reduce the distortion distortion of tonequality, the diameter that loud speaker will promote the voice coil loudspeaker voice coil 6 of plate diaphragm 1 double vibrations is chosen as 0.5-0.8 times of diameter of plate diaphragm 1, and promptly the node of plate diaphragm 1 is justified 11 diameter.Described node is meant plate diaphragm 1 when resonance, and the amplitude of this position approaches 0 geometric point.Circle of the common formation of the set of these geometric points is node circle 11.The be adhesively fixed lower sidewalls surface of plastic pallet 5 of voice coil loudspeaker voice coil 6 one ends, the diameter of voice coil loudspeaker voice coil 6 equals the diameter of node circle 11, the node circular diameter of recommendation be the plate diaphragm diameter 0.5-0.8 doubly.When energized position is node, structure will can not produce resonance; Significantly reduced the distortion distortion degree of loud speaker.
