A through channel passes the whole supporting portion for connecting the space with outside to transmit the sound produced by the loudspeaker. The ear cushion has a through hole passing through the whole ear cushion. A top of the through hole is enlarged to form a first receiving cavity for receiving a first damper. The first damper can seal against the outside region preventing the particles into the in-ear headphone and damaging the loudspeaker. Also, the first damper adjusts the sound effect of the in-ear headphone. Moreover, the first damper can be taken off the first receiving cavity easily and replaced by another one. So, the user can experience varies sound effect by changing the first damper.

Acoustic enclosure for loudspeakers

Номер: US20130105244A1

Автор: Ángel Julio Moretón Cesteros

Принадлежит: Individual

Acoustic enclosure for mounting loudspeakers ( 1 ) that contains a certain number of curved-profile guides ( 8 ) arranged radially beside one another at a specific distance and forming a ring ( 7 ), between which the sound from the loudspeaker is propagated from the central space ( 6 ) to the outer ring ( 9 ), which it enters obliquely as a result of the curvature of the guides. Since said ring ( 9 ) contains no elements against which the sound can be reflected back into the conduits, it works like a closed circuit or track that the sound passes through until it is exhausted, keeping the inner face of the membrane of the loudspeaker free of disturbances that, in conventional enclosures, are caused by the reflected sound when it hits the membrane during the lifetime of the sound, thereby eliminating the distortion and alterations of the natural response linearity of the loudspeaker from this source.

Provided is a technique for improving frequency characteristics by an acoustics-related method so that a sound is heard with natural frequency characteristics when a sound-isolating earphone is fitted in a human ear. A sound-isolating earphone is provided with two or more electroacoustic transducers, wherein independently generated sound waves are passed through isolated sound leading pipes and are mixed just before an entrance of an external auditory canal, and a sound wave of which is twice the difference between path lengths of the two sound leading pipes is attenuated. This serves to provide an easy-to-hear improved sound quality by suppressing the sound wave at around 6 kHz that is transmitted with characteristically high intensity in a sound-isolating earphone.

Systems, devices and methods for communication include an ear canal microphone configured for placement in the ear canal to detect high frequency sound localization cues. An external microphone positioned away from the ear canal can detect low frequency sound, such that feedback can be substantially reduced. The canal microphone and the external microphone are coupled to a transducer, such that the user perceives sound from the external microphone and the canal microphone with high frequency localization cues and decreased feedback. Wireless circuitry can be configured to connect to many devices with a wireless protocol, such that the user can receive and transmit audio signals. A bone conduction sensor can detect near-end speech of the user for transmission with the wireless circuitry in noisy environment. Noise cancellation of background sounds near the user can improve the user's hearing of desired sounds.
