    Abstract: An in-ear earphone housing has a speaker driver installed therein. The driver has a diaphragm with a front face and a rear face, and a motor to vibrate the diaphragm in accordance with an audio signal. A back volume chamber is positioned behind the driver within the earphone housing. The diaphragm is part of a wall of the back volume chamber. An acoustic mass loading membrane that is part of a wall of the back volume chamber, and that is to vibrate in response to acoustic waves produced by vibration of the diaphragm impinging on a front face of the membrane, is provided. Other embodiments are also described and claimed, including a polymer production process for an elastic material.

    Abstract: A first earphone of an earphone system includes a first magnet assembly and a first voice coil. A second earphone of the earphone system includes a second magnet assembly and a second voice coil. The second magnet assembly has a magnetic polarity that is opposite to the first magnet assembly. The current direction in the second voice coil is reversed relative to the current direction in the first voice coil. The first earphone and the second earphone attract each other because of the opposite magnetic polarity between the first magnet assembly and the second magnet assembly.

    Abstract: A first driver housing and a second driver housing are positioned inside an earbud cup. The first driver housing has a rear side, a front side, a top face a bottom face, and a sound output tube extending from the front side. The second driver housing has a top side, a bottom side, a front face, a rear face, and a sound output opening formed in the front face of the second housing with essentially no tube extending therefrom. The rear face of the second housing is disposed a) adjacent to the front side of the first housing, and b) behind an exit of the sound output tube of the first housing. Other embodiments are also described and claimed.

    Abstract: A media system and a method of using the media system to accommodate hearing loss of a user, are described. The method includes selecting a personal level-and-frequency dependent audio filter that corresponds to a hearing loss profile of the user. The personal level-and-frequency dependent audio filter can be one of several level-and-frequency-dependent audio filters having respective average gain levels and respective gain contours. An accommodative audio output signal can be generated by applying the personal level-and-frequency dependent audio filter to an audio input signal to enhance the audio input signal based on an input level and an input frequency of the audio input signal. The audio output signal can be played by an audio output device to deliver speech or music that the user perceives clearly, despite the hearing loss of the user. Other aspects are also described and claimed.
