Problems solved by technology

However, the sound quality may not be optimal for the user as sound may leak from the earphones and not reach the ear canal
Also, due to differences in ear shape and size, different volumes of sound leak through, thus resulting in inconsistent acoustic performance between users

Abstract

The disclosure relates to an earphone having an acoustic tuning mechanism. The earphone comprises an earphone housing having a body portion acoustically coupled to a tube portion extending from the body portion, the body portion having an acoustic output opening to output sound from a driver positioned therein into an ear canal of a wearer; and an acoustic tuning member positioned within the body portion for acoustically coupling the driver to the tube portion, the acoustic tuning member defining a back volume chamber for the driver and forming an acoustic pathway for outputting sound from the back volume chamber of the driver to the tube portion, so as to improve acoustic performance of the earphone.

Description

technical field [0001] An embodiment of the invention relates to an earphone assembly with an acoustic tuning mechanism. Other embodiments are also described and claimed. Background technique [0002] Whether listening to an MP3 player while traveling or listening to a hi-fi stereo system at home, consumers are increasingly opting for in-canal and in-the-ear headphones for their listening pleasure. These two types of electro-acoustic transducing devices have a small form factor housing that houses the receiver or driver (ear speaker). The small profile housing offers wearing convenience while also delivering very good sound quality. [0003] In-canal earphones are generally designed to fit within and seal against the user's ear canal. Thus, in-canal earphones have an acoustic output tube portion extending from the housing. The open end of the delivery tube is insertable into the wearer's ear canal. The tube portion is generally formed or fitted with a flexible elastic t...
