Description

FIELDOFTHEINVENTION

[0001]Thepresentinventionrelatestoaloudspeakersystemandmoreparticularlytoanewyokeconfigurationthatprovidesimprovedmagneticfieldstrengthaswellasahighersoundpressurelevel.

BACKGROUNDOFTHEINVENTION

[0002]ModernaudiovideoequipmentsuchasLCDTV,PlasmaTV,andwallmountedDVDplayersarebecomingincreasinglythinnerindimension.Thisinfluencesthedevelopmentofloudspeakersystemswiththeobjectivetobeasthinaspossibleorassmallaspossiblefortheenclosuresize,whileretaininghighqualitysound.

[0003]Toproduceagoodsoundqualityoftheloudspeakerdriver,appropriateloudspeakerparametersarerequired.Oneparameterisahighmagneticfieldstrength（B）atthemagneticgapofthedrivermotorsystem.Thebenefitofahighermagneticfieldstrength（B）ishighersoundpressurelevel（SPL）.

[0005]Byusingtheinventedintegratedmultiyokestructure,thesizeproblemmaybemitigated.Theintegratedmultiyokestructuremaybeusedinbi-polar,tri-polar,quadro-polar,penta-polarorhexa-polarloudspeakersystems.Theadvantageofthissystemisbothwidersounddispersionandhighermagneticfieldstrength（B）inasmallerloudspeakerenclosuresize.Thisinventionisapplicablefortelevisionloudspeakers,highfidelityloudspeakers,carloudspeakers,multimedialoudspeakers,ceilingloudspeakers,sub-woofers,conetype,dometype,andhorntypedriversamongothers.

SUMMARYOFTHEINVENTION

[0006]Oneobjectofoneembodimentofthepresentinventionistoprovidealoudspeakerdrivermotorsystemforcombininganddrivingtwoormoreloudspeakers,withanintegratedyokestructureforprovidingapathforthemagneticfieldofeachdriver.
