Embodiment Construction

[0126] Figures 1a-1c Various types of prior art earphones are shown. Each type of earphone is characterized by the size and / or the manner in which the earphone is secured to the ear of the user of the earphone.

[0127] Figure 1a A prior art full-cover earphone device 12 is shown. Full-circle headphone devices are also commonly referred to as full-size headphones, circumaural headphones, or over-ear headphones. Earphones of this type are generally substantially larger than the pinna 72 of the user wearing the earphone. The pinna may be understood as the visible part of the outer ear 70 and may also be referred to as the auricle. The full-cover earphone device 12 is typically secured to the user's head 73 by the use of straps 14 that connect the two full-cover earphone devices 12 (one for each ear) as a single device and in the direction of the ear canal 71 Apply pressure to the user's head to keep the full-coverage headset in place. Therefore, the fixation of the full-c...

Abstract

The present invention relates to an in-ear headphone device comprising a microphone and a loudspeaker having a loudspeaker diaphragm, wherein the device is arranged to provide a noise cancelling audio signal to the loudspeaker. The speaker and microphone are acoustically coupled within the device housing, and the device includes a sound tube that couples the device to the user's ear canal. The sound tube is associated with a sound tube axis that defines a projection plane perpendicular to the sound tube axis. The loudspeaker and the microphone are arranged such that the projection area of ​​the speaker diaphragm on the projection plane does not intersect the projection area of ​​the microphone on the projection plane. The present invention also relates to a set of in-ear earphone devices, comprising a first in-ear earphone device and a second in-ear earphone device.

Description

technical field [0001] The present invention relates to an in-ear headphone device with active noise control. Background technique [0002] There are various types of earphones used to reproduce sound, such as over-ear earphones, on-ear earphones, and in-ear earphones, such as in-ear earphones that extend into the area where the earphones are worn. in the user's ear canal. [0003] Some earphones of the above earphone type may further comprise a microphone arranged to record sounds, eg sounds external to the earphones, or sounds existing within an enclosed / hidden volume in front of the ear canal of the user wearing the earphones. Such sound recordings can be used for telephony purposes or for active noise control. [0004] Implementing active noise control in in-ear headphone devices remains a challenge, where size constraints of headphone components, quality of components, and headphone stability must be carefully balanced to provide a superior sound and user experience t...
