A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

A sound management enclosure, production, and recapture device may include a generally symmetrical design and may be constructed and arranged to optionally internally mount components therein. The sound management device may be constructed and arranged to alter, focus, or dissipate sound waves within a predictable environment in order to enhance the associated effects. Sound capturing devices, such as microphones, may be placed within the sound management enclosure for transmission to an external system for recording or projection.

According to certain embodiments, an electronic device comprises: first housing; a first substrate disposed in the first housing; a second housing; a second substrate disposed in the second housing; a flexible printed circuit board (FPCB) connecting the first substrate and the second substrate; a hinge hingably connecting the first housing and the second housing; a hinge cover covering the hinge, the hinge cover having a microphone hole formed therein; at least one first microphone disposed in the first housing; a speaker disposed in the second housing; and at least one second microphone disposed in the hinge, and configured to collect external sound through the microphone hole formed in the hinge cover, and mounted on a portion extending from the FPCB.

An electronic device is provided. The electronic device includes a housing including a first housing and a second housing, a hinge configured to rotatably connect the first housing and the second housing, a flexible printed circuit board including a connection part disposed at the hinge, and configured to connect an electronic component disposed at the first housing and an electronic component disposed at the second housing, and a microphone module disposed at the connection part of the flexible printed circuit board.

This disclosure describes a ceiling tile microphone system that includes a plurality of microphones coupled together as a microphone array and used for beamforming processing, one or more separate processing devices that couple to the microphone array, where one or more separate processing devices further include beamforming, acoustic echo cancellation, and adaptive acoustic processing; a single ceiling tile with an outer surface on the front side of the ceiling tile where the outer surface is acoustically transparent, the microphone array combines with the ceiling tile as a single unit, the ceiling tile being mountable in a drop ceiling in place of a ceiling tile included in the drop ceiling; where the system is used in a drop ceiling mounting configuration; where the microphone array couples to the back side of the ceiling tile and all or part of the system is in the drop space of the drop ceiling.

The present disclosure is related to a mobile phone cover providing passive noise reduction of at least one microphone audio input signal, comprising a supporting frame (13). The supporting frame (13) is arranged with an extension element with a compartment (15) facing upwards with a partly open surface on a same side as a display surface of the mobile phone, the compartment (15) is adapted to support a porous body (17) providing the passive noise reduction.
