Embodiment Construction

[0018] In a first aspect, there is provided an in-ear earphone 20 with a variable degree of noise isolation, such as image 3 Shown is a cross-sectional view of the first embodiment shown in use in the user's ear 18 . The earphone 20 includes a housing 22 with a serpentine duct 24 capable of housing at least one transducer 26 in a body 28 of the housing 22 . In the exemplary embodiment only one transducer 26 is shown. Earphone 20 may include a cushion 30 that contacts the wall of a user's ear canal 32 . Gasket 30 may be mounted to serpentine duct 24 of housing 22 . At least one opening in the housing 22 or the cushion 30 may cause a leak, which allows ambient noise to enter the user's ear canal 33 . The at least one opening will be described in more detail in the following paragraphs of this section. The size of each of the at least one opening may vary. Allowing ambient noise to enter the user's ear canal can help improve the user's safety while the user is exercising ou...

Abstract

There is provided an insert ear bud earphone with variable noise isolation. The earphone includes a housing with a serpentine channel which is able to contain at least one transducer in a main body of the housing; and a cushion which contacts a user's ear canal wall, the cushion being mounted on the serpentine channel. There is preferably at least one opening in either the housing or the cushion which causes leakage and allows ambient noise to enter the user's ear canal. There is also provided a cushion for an insert ear bud earphone. Finally, there is provided a method to enable variable noise isolation in an insert ear bud earphone comprising an inclusion of at least one opening in either a housing of the earphone or a cushion mounted on the earphone which causes leakage and allows ambient noise to enter a user's ear canal.

Description

technical field [0001] The present invention relates to in-ear earphones capable of varying the degree of noise isolation and pads for use with the earphones. The invention also relates to a corresponding method for varying the degree of noise isolation. Background technique [0002] Ear bud earphones, which are inserted into the user's ear canal during use, are becoming increasingly popular for use with portable media devices and mobile phones. One reason these headphones are popular is because of their ability to isolate external noise that can adversely affect the sound emanating from the headphones. [0003] However, for this reason, the use of such headphones can be dangerous for the user in certain situations. This kind of headphones can usually isolate the noise in a specific band by more than 20dB. When the user is using such earphones while jogging or cycling outdoors, this isolation may adversely reduce the user's attention to the surrounding environment / circums...
