When there is represented a relative motion of a first component (lower traveling body 410, upper revolving body 420) and a second component (upper revolving body 420, bucket 445 (working unit)) that constitute working machine 40, based on a result of detecting an operation aspect of a remote operation device 20, control is performed on individual sound output aspects of a plurality of sound output devices 2220, 2221 and 2222, each arranged at different locations in a remote operation space for the operator who operates the remote operation device 20.

Disclosed herein is a system for facilitating stress adaption in a workstation. Accordingly, the system may include microphones disposed on the workstation. Further, the one or more microphones may be configured for generating first sound signals of first sounds associated with an environment of the workstation. Further, the system may include a processing device communicatively coupled with the microphones. Further, the processing device may be configured for analyzing the first sound signals, determining first sound characteristics of the first sounds, determining second sound characteristics of second sounds, and generating second sound signals for the one or more second sounds. Further, the system may include acoustic devices disposed on the workstation. Further, the acoustic devices may be communicatively coupled with the processing device. Further, the acoustic devices may be configured for emitting the second sounds based on the second sound signals. Further, the second sounds destructively interfere with the first sounds.

Disclosed is a massage device according to one embodiment of the present disclosure. The massage device comprises: a body structure for forming an area to accommodate at least one portion of the body of a user and defining the outer shape of the massage device; a massage module for supplying a massage function to the at least one portion of the body of the user accommodated in the area in the body structure; an input unit for receiving an input of an arbitrary form from the user of the massage device; a display for displaying massage mode screen information which can be selected by the user of the massage device; and a control unit for controlling one more operations of the massage device on the basis of at least a part of the input of an arbitrary form received by the input unit.

This application discloses a device to project sound to a specific person while keeping the sound away from others nearby. The device has various parametric speakers arranged in a pattern to project sounds in a narrow field while preventing dispersion of sounds to nearby areas. The device can be connected to other electronic equipment by wires or wirelessly, and can be removed and used in different settings. This device has particular application in delivering sounds to infants and toddlers to sooth them while the same sounds are not heard by adults nearby.

An auto-orienting loudspeaker assembly for a vehicle seat includes a housing arranged to be received within a rear side of the vehicle seat, an enclosure rotatably mounted to the housing, the enclosure having a nonuniform weight distribution, and a loudspeaker disposed within the enclosure and having an initial orientation. A change in an angular position of the vehicle seat results in a passive rotation of the enclosure with respect to the housing to substantially maintain the initial orientation of the loudspeaker as the angular position of the vehicle seat changes.
