Headphones or a headset with a planar magnetic system

Abstract

The invention relates to the field of electrical communication, particularly to the design of headphones or headset which uses an acoustic radiator with a planar magnetic system that can be used to change ear cup cushion of headphones or headset. Headphones or the headset comprises of at least one housing with an acoustic radiator having a planar magnetic system placed therein, equipped with an ear cup cushion located on the outer surface of the radiator. The ear cup cushion and housing is performed in disconnected way. The ear cup cushion is rigidly connected to at least one acoustically transparent ferromagnetic screen connected to the housing by means of an interaction of the ferromagnetic screen with the magnetic field of the planar magnetic system on the outer surface of the radiator. The magnetic conductivity of the ferromagnetic screen is sufficient to increase the magnetic induction in a gap of the magnetic system of the radiator and to hold the ear cup cushion with a ferromagnetic shield on the housing. When the ear cup cushion is attached to the hosing, the ferromagnetic screen located on the outer surface of the radiator increases the magnetic conductivity of the outer portion of the magnetic core of the radiator and increases the magnetic induction in the gap of the magnetic system of the radiator and, accordingly, its sensitivity.
