Abstract: In a robot control system, the operation of a mobile robot that moves autonomously inside a facility is controlled based at least on an image captured by a photographing device that photographs a blind area located at a blind angle to the mobile robot. When entry of the mobile robot into a predetermined area corresponding to the blind area is detected, the amount of information obtainable from an image captured by the photographing device is increased.

Abstract: A robot control system according to the present embodiment is a robot control system that controls a plurality of transport robots that is travelable autonomously in a facility. The robot control system: acquires error information indicating that an error has occurred in a first transport robot; acquires transported object information related to a transported object of the first transport robot; determines a second transport robot able to transport the transported object of the first transport robot among the transport robots based on the transported object information and the error information; and moves the second transport robot to a transfer location of the transported object of the first transport robot.

Abstract: A mobile robot receives first transmission information transmitted from a server device to manage the mobile robot in a state where wireless communication with the server device is possible, directly executes wireless communication with another mobile robot among the mobile robots and executes a reception process of receiving the first transmission information transmitted from the server device to manage the mobile robot from the other mobile robot in a case where wireless communication with the server device is not possible.

Abstract: A speaker apparatus is configured such that a speaker unit including a single magnetic circuit system, a plurality of vibration systems and a case is housed inside a speaker box. In the speaker unit, magnetic gaps having a magnetic field of the same magnitude are defined by a magnet holder, a magnet and a yoke in each of the vibration systems. In one vibration system and the other vibration system, voice coils are wound around voice coil bobbins in directions reverse to each other. Consequently, the vibration systems are moved in directions opposite to each other by the same force by applying the same electric signal to the voice coil in each of the vibration systems from an amplifier. Therefore, acoustic waves are radiated in the directions opposite to each other.

Abstract: A loudspeaker comprises a frame, a magnetic circuit unit, a vibration unit and a snap fastening device. The frame has a recess. The magnetic circuit unit is received in the recess of the frame. The magnetic circuit unit includes a yoke. The vibration unit is received in the recess of the frame. The snap fastening device connects the yoke, which is inserted into the recess of the frame, to the frame.

Abstract: A speaker apparatus to be mounted on a vehicle includes a speaker unit and a mounting device. The speaker unit has a frame. The mounting device mounts the frame of the speaker unit on a panel member of a vehicle body. The mounting device includes insulators, which prevent vibration, which is caused by operation of the speaker unit in any direction, from being transmitted to the panel member in any direction.

Abstract: A loudspeaker apparatus is provided with a loudspeaker unit attached to an inner panel. The inner panel of the loudspeaker unit is provided with: an opening to which the loudspeaker unit is attached; a volume unit in which the loudspeaker unit is housed from the opening to form a closed space; and a groove passing through to the volume unit. The loudspeaker unit is housed in the volume unit, and a rear space of the loudspeaker unit in the volume unit is used as an acoustic volume unit of the loudspeaker unit.

Abstract: A speaker device which makes it possible to prevent the entry of foreign matter such as magnetic dust into a magnetic gap through the gap between a diffuser and a voice coil bobbin, to thereby improve the operational reliability and service life of the product. In a speaker device in which a diffuser that improves directional characteristics is provided on a front side of a center pole that makes up a magnetic circuit, the diffuser has a magnet portion which is provided in a ring shape making one round around its outer periphery and is magnetized in a radial direction. As foreign matter such as magnetic dust is attracted by the magnet portion of the diffuser, the entry of the foreign matter into a magnetic gap side is prevented.

Abstract: A speaker unit in which an open end of each of acoustic tubes is disposed on an upper surface of a casing is produced. The speaker unit is mounted inside a seat, for example, to an upper position of an inside of a backrest of the seat via a connecting member or the like. Thereby, the open ends of the acoustic tubes are disposed at a position near both ears of a seated person. Since low-frequency sound can be reproduced to an area near both the ears of the seated person, so much output sound pressure level of the drive speaker is not needed. Therefore, a drive speaker of a small bore diameter can be applied to the speaker unit, and the speaker unit itself can be made compact and light. The speaker unit is mounted inside the backrest of the seat, for example, and it is not necessary to take the trouble to ensure a place for placing the speaker unit around the seat.

Abstract: It is to consolidate the connecting structure of a vibration system of a speaker apparatus. A first diaphragm and a voice coil bobbin are connected by a connecting member. A second diaphragm attached to the first diaphragm is attached to the connecting member. Alternatively, reinforcing member is attached to the first diaphragm and the connecting member.

Abstract: A speaker unit is fitted to a speaker-unit mounting hole of a baffle plate provided with the speaker-unit mounting hole. The speaker unit is fitted to at least one of service holes provided in a door panel (inner panel) of a door apparatus for a vehicle.
