A loudspeaker system includes a subwoofer. The subwoofer includes a housing having a plurality of walls which together define an acoustic cavity. The plurality of walls includes a front wall, a rear wall, a top wall, a bottom wall, and a plurality of sidewalls extending between the top and bottom walls and between the front and rear walls. A first transducer mounted to the front wall of the housing. The first transducer includes a diaphragm having a major axis and a minor axis. The major axis has a fist end proximate the bottom wall and an opposite, second end proximate the top wall, such that the major axis is arranged vertical, relative to ground when the subwoofer is rested on its bottom wall. The top wall has a handle such that the loudspeaker can be carried with the major axis arranged vertical to ground.

A monitor speaker assembly for includes a drum shell. A plurality of first lugs is each of the first lugs is coupled to the drum shell. A mesh screen is attachable to the drum shell and the mesh screen is comprised of a fluid permeable material to pass sound through the mesh screen. A speaker is disposed within the drum shell to emit audible sounds outwardly from the drum shell. A receiver is coupled to the drum shell and a tripod is insertable into the receiver on the drum shell thereby facilitating the drum shell to elevated. In this way the drum shell can direct the speaker toward a drummer thereby facilitating the drummer to hear audible sounds emitted by the speaker.

A MEMS microphone includes a substrate, a diaphragm disposed over the substrate to cover the cavity, the diaphragm defining an air gap together with the back plate, and the diaphragm being spaced apart from the substrate, a back plate disposed over the diaphragm and in the vibration area, an upper insulation layer to cover the back plate, a plurality of chamber portions provided in the supporting area, a lower insulation layer provided under the upper insulation layer and on the substrate, and an intermediate insulation layer provided between the lower insulation layer and the upper insulation layer and disposed further from the vibration area than the chamber portions.

The present disclosure provides an acoustic output apparatus including one or more status sensors, at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, at least two first sound guiding holes, and at least two second sound guiding holes. The status sensors may detect status information of a user. The low-frequency acoustic driver may generate at least one first sound, a frequency of which is within a first frequency range. The high-frequency acoustic driver may generate at least one second sound, a frequency of which is within a second frequency range including at least one frequency exceeding the first frequency range. The first and second sound guiding holes may output the first and second spatial sound, respectively. The first and second sound may be generated based on the status information, and may simulate a target sound coming from at least one virtual direction with respect to the user.

An apparatus includes a vibration member and a first cover disposed at a rear surface of the vibration member. The apparatus also includes a first vibration apparatus disposed at a rear surface of the first cover and configured to vibrate the vibration member. The apparatus includes a first enclosure member disposed at the rear surface of the first cover and at the rear surface of the vibration member. The apparatus also includes a first rear vibration member disposed at the first enclosure member.

A communications device is described that may include a system housing, a microphone array, a loudspeaker, and a loudspeaker housing. The loudspeaker housing is configured to minimize acoustic coupling between the loudspeaker and the microphone array, and at least a portion of the loudspeaker housing is positioned outside of the system housing. The loudspeaker housing may include a plurality of loudspeaker housing mounts. The loudspeaker housing may include first and second halves which may have a gasket between them. The gasket between the first half and the second half of the loudspeaker housing may be configured to dampen vibrations.

An acoustic device includes a main body case, a vibrating body provided inside of the main body case, a magnetic circuit unit disposed in front of the vibrating body in a sound emitting direction of the vibrating body, a coil located inside of a magnetic gap of the magnetic circuit unit, a bobbin configured to support the coil and vibrate along with the vibrating body, and a damper configured to connect the main body case to the bobbin. The damper is disposed in the rear of the vibrating body, and a damper regulation unit is provided in the rear of the damper at a position facing the damper.

One or more sensors are configured to contextualize a series of user generated movements to control one or more electronic devices. For example, a set of earphones comprises one or more sensors for sensing a location of the earphones. The one or more sensors enable earphones such as a pair of bluetooth or earphones wirelessly coupled to a bluetooth enabled electronic device, the capability to understand the configuration of use of the earphones. Based on a location and use or non-use of the earphones, one or more contextual responses is able to be applied for a given action. In addition, a garment comprises one or more sensors for sensing a motion of a user as the garment is being used. The one or more sensors allow the user to control one or more electronic devices through a series of user generated movements.

An equipment part for a vehicle, including a wing device having at least one wing. The wing is pivotably about a pivot axis between a first pivot position and a second pivot position. The wing has a base part and an extension part that is supported movably relative to the base part in a translatory manner between a base position and an extended position. An adjusting device has at least one motor drive and a transmission for executing the pivoting movement as well as the translatory movement of the wing. By way of the transmission, a conversion takes place of a rotary movement of the drive to a translatory movement of the extension part, wherein a torque about the axis of rotation is produced in the base part, with which torque the wing is pivotable between the first pivot position and the second pivot position.

A voice-controlled electronic device that includes a device housing having a longitudinal axis bisecting opposing top and bottom surfaces and a side surface extending between the top and bottom surfaces. The device can further include one or more microphones disposed within the device housing and distributed radially around the longitudinal axis; a processor configured to execute computer instructions stored in a computer-readable memory for interacting with a user and processing voice commands received by the one or more microphones and first transducer and second transducers configured to generate sound waves within different frequency ranges.
