Abstract
The utility model relates to a multi-layer compound panel vibration film for a loudspeaker, formed by bonding a plurality of layers of paper sheets with light materials. The utility model has the advantages that the multi-layer compound panel vibration film overcomes the shortcomings when adopting a cone vibration film, can eliminate front cavity effect, has wider directive property, obtains flat sound pressure frequency property, has good tone quality, small volume and light weight, meets the developing demand of loudspeaker to be thin, light and small, overcomes the shortcomings of the flat vibration film, decreases the cutting vibration of the vibration film, improves the middle-high frequency sound pressure frequency property, increases the frequency width and improves the tone quality.
Description
Technical field
The utility model relates to a kind of diaphragm of loudspeaker, particularly a kind of loud speaker MULTILAYER COMPOSITE plate diaphragm.
Background technology
The diaphragm of loudspeaker mainly adopts conical diaphragm and plate diaphragm at present, adopt conical diaphragm, the cup effects is big, directive property is narrower, volume is big, heavy, progress along with the epoch, loadspeaker structure trends towards approaching, light, little direction develops, and therefore the shortcoming that adopts conical diaphragm to exist will be eliminated by market; Adopt the deficiency of plate diaphragm to be: owing to cut apart vibration, the sound pressure frequency characteristic of medium-high frequency is relatively poor, and frequency range is narrower, and tonequality is also bad.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of loud speaker MULTILAYER COMPOSITE plate diaphragm.The utility model for achieving the above object, the technical scheme of being taked is: a kind of loud speaker MULTILAYER COMPOSITE plate diaphragm, comprise plate diaphragm, it is characterized in that: described plate diaphragm comprises several layers of page, the bonding formation of lightweight material.
The beneficial effects of the utility model: overcome the deficiency that adopts conical diaphragm, can eliminate the ante-chamber effect, directive property is wideer, obtains smooth sound pressure frequency characteristic, tonequality is good, the requirements of the times that little, in light weight, the suitable loud speaker of volume develops to thin, light, little direction; Overcome the deficiency that adopts plate diaphragm, this vibrating diaphragm has reduced cuts apart vibration, has improved the sound pressure frequency characteristic of medium-high frequency, has increased frequency range, has improved tonequality.
