Device for realizing steering wheel key control on vehicle-mounted loudspeaker

摘要: The invention relates to a device for realizing steering wheel key control on vehicle-mounted loudspeaker. comprises dashboard and wheel, wherein box is separately fixed the wheel; an upper positioning mechanism coaxially arranged below in sleeving manner; lower above conductive base mechanism; elastic sheets are at bottom end of paralleling tail ends can be closely collided with surface PCB mechanism, electrically connected PCB; when rotated, three slide along circular trace. Under condition not changing structure automobile loudspeaker adapt more models; furthermore, due design contact metal sheets, phenomenon wire twisting avoided even if reliable connection signal kept.
