Title:
EARMUFF FOR EARPHONE AND EARPHONE PROVIDED WITH EARMUFF
Document Type and Number:
WIPO Patent Application WO/2018/045498
Kind Code:
A1
Abstract:
An earmuff (1) for an earphone and the earphone provided with the earmuff (1). The earmuff (1) for an earphone consists of an elastic annular sponge and a fabric cladding outside the annular sponge, and multiple air discharging through holes (3) are formed in the fabric. By forming holes in the surface of the fabric of the earmuff (1) for an earphone, frequency responses of the earphone on a middle frequency and a low frequency are effectively adjusted. At the moment that the earphone is worn, part of the air pressure in an ear canal and part of the air pressure in an earphone cavity are offloaded from the holes of the earmuff, so that a diaphragm of the earphone is protected, and the diaphragm of the earphone is prevented from being deformed due to the excessively high instantaneous air pressure, and accordingly silence, worse distortion and other undesirable phenomena of a loudspeaker caused at the moment that the earphone is worn are decreased.
