Title:
ELIMINATING DEVICE OF DISTURBING SIGNAL
Document Type and Number:
Japanese Patent JPS59204307
Kind Code:
A
Abstract:

PURPOSE: To secure the ability to exclude an external disturbing signal without exerting any evil influence upon the original performance of an acoustic equipment, by forming part of a signal transmission line of a magnetic body.

CONSTITUTION: The 1st and the 2nd conductive patterns 11 and 12 which transmit sound signals are fixed to an insulating substrate 10. Those 1st and the 2nd conductive patterns 11 and 12 are cut partially and their cut parts are connected electrically to a speaker terminal 15 directly or through lead wires 13 and 14. This terminal 15 is connected to a speaker or another acoustic equipment through a connection cord. Further, the lead wires 13 and 14 are inserted by a cylindrical magnetic body 16. Thus, the ability to exclude external disturbing signals is secured without exerting any evil influence upon the original performance of the acoustic equipment.
