Abstract
An earphone without impulse noise for protection against conductive hearing loss includes an earphone housing (40) and a loudspeaker (50) mounted in a sound chamber (43) therein. A front end of the earphone housing has an earplug (41) adapted to be hanged between the tragus and the antitragus of the external ear while a rear end thereof has a hood (42) with a hollow sound chamber (43). A
loudspeaker is supported in the hollow sound chamber of the hood around which a plurality of sound holes (44) are distributed, wherein a sound output end of the loudspeaker must be positioned facing to the hood and opposite to the earplug. A
conductive cord (60) is connected at the bottom end of the earphone housing for transmitting electric current to the loudspeaker.
