An entertainment system for a vehicle, the system including: a sound emitting module including multiple sound emitting units, wherein the sound emitting module is adapted to be arranged such that the multiple sound emitting units are distributed along the transverse extension of a windshield of the vehicle and to emit sound towards the windshield, and a display device arranged between the sound emitting module and an occupant seating position, wherein the display device is arranged to cover the sound emitting module as seen from the occupant seating position. The disclosed entertainment system provides the advantage of integrating a more advanced sound system in the form of a sound emitting module including multiple sound emitting units.

This application provides a speaker and a mobile terminal. The speaker includes a housing and a kernel located in the housing, where there is a front cavity and a rear cavity in the housing, the front cavity is in communication with the outside, and the rear cavity is an isolated cavity. In addition, to reduce a space area occupied by the entire speaker, the front cavity and the rear cavity are disposed in a stacked manner when being disposed. Specifically, the front cavity and the rear cavity are at least partially stacked along a thickness direction of the kernel. Therefore, the rear cavity is disposed in space of the entire speaker in the thickness direction of the kernel, to reduce an area occupied by the entire speaker in the mobile terminal on the premise that a size of the rear cavity meets a requirement.

A commercial lighting system, the system comprising, an integral housing adapted to be coupled to a ceiling of a building, a lighting unit mounted to the integral housing and a loudspeaker assembly mounted to the integral housing, the loudspeaker assembly comprising a low directivity index, and oriented to provide an acoustic sound signal from the integral housing to a listener in an area of the building comprising the ceiling.

A compact electronic device has a touch sensor and/or a microphone that are concealed within a housing at least partially wrapped by an acoustically porous cover. In some implementations, the touch sensor includes a sensing portion and a contact portion extending from the sensing portion. While the sensing portion is placed in proximity to an interior surface of the housing to detect a touch on the housing, the contact portion is bent to electrically couple the sensing portion to a circuit board via two distinct electrical paths. In some implementations, an exterior surface of the housing includes a sealing area surrounding an aperture on the housing, and the acoustically porous cover is affixed to the sealing area via an adhesive. The adhesive covers the sealing area and permeates a thickness of the acoustically porous cover, thereby enabling formation of a controlled sound path to access the microphone via the aperture.

The present disclosure relates to a pair of glasses. The pair of glasses may include a frame, one or more lenses, and one or more temples. The pair of glasses may further include at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, and a controller. The at least one low-frequency acoustic driver may be configured to output sounds from at least two first guiding holes. The at least one high-frequency acoustic driver may be configured to output sounds from at least two second guiding holes. The controller may be configured to direct the low-frequency acoustic driver to output the sounds in a first frequency range and direct the high-frequency acoustic driver to output the sounds in a second frequency range. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.

An open audio device includes an acoustic radiator that emits front-side acoustic radiation from its front side and emits rear-side acoustic radiation from its rear side, a front acoustic cavity that receives front-side acoustic radiation, and a rear acoustic cavity that receives rear-side acoustic radiation. At least one sound-emitting opening is acoustically coupled to the front acoustic cavity or the second acoustic cavity. The open audio device also includes a removable accessory that includes an acoustic transmission line that is acoustically coupled to the at least one sound-emitting opening when the removable accessory is attached to the open audio device.

The present invention describes a loudspeaker comprising a housing and a plurality of sound transducers arranged inside said housing, where the housing has two sides arranged on either side of a x-y plane with a mutual distance between said sides measured along a z-axis orthogonal to the x-y plane, and a front facing side and a rear facing side, and a top and a bottom, wherein a. A first sound transducer is arranged inside a first cavity inside said loudspeaker housing, where said first cavity has a narrow first slit in the y-direction provided in the rear facing side, where said first slit has a width z1 in the z-direction, and a length y1 in the y-direction where the length y1 in the y-direction is larger than the width z1 in the z-direction; b. A second sound transducer is arranged inside a second cavity inside said loudspeaker housing, separate from said first cavity, and where said second cavity is provided with a narrow second slit in the y-direction provided in the front facing side, where said second slit has a width z2 in the z-direction, and a length y2 in the y-direction, where the length y2 in the y-direction is larger than the width z2 in the z-direction.

Various implementations include seats and related loudspeaker assemblies. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly associated with the backrest portion. The loudspeaker assembly can have an acoustic directivity angled upward above a nominal ear position of an occupant.

A speaker apparatus includes a pair of left and right speaker blocks that respectively have acoustic output sections and that are arranged inside a backrest. The pair of speaker blocks are arranged horizontally side by side relative to a headrest located on a front surface side of the backrest, and at least part of the headrest is located within a range of a nominal directivity angle of acoustics output from the acoustic output sections. This ensures that, of the acoustics output from the acoustic output section of the speaker block on the left side, at least some acoustics that head for the right ear are blocked by the headrest and that, of the acoustics output from the acoustic output section of the speaker block on the right side, at least some acoustics that head for the left ear are blocked by the headrest.
