Abstract: A distance measurement apparatus executes transmitting and receiving a signal with another device; acquiring first and second phases when the other device receives signals of first and second frequencies from the distance measurement apparatus; measuring third and fourth phases when the signals of first and second frequencies are received from the other device; measuring a distance to the other device based on the acquired first and second phases, the first and second frequencies, and the measured third and fourth phases; and setting randomly a transmission order, and the first and second frequencies. The transmission order indicates an order of transmitting the signal of the first frequency by the other device, transmitting the signal of the first frequency by the distance measurement apparatus, transmitting the signal of the second frequency by the other device, and transmitting the signal of the second frequency by the distance measurement apparatus.

Abstract: With a vehicle-mounted acoustic device, a bass-reflex speaker system, composed of an enclosure, ducts, and a speaker unit, is accommodated in a head restraint. Each duct has a large ratio of the duct length to the area of the duct cross section to increase the load mass of air in the duct, so that the resonant frequency of the vibration unit in the speaker unit can be set in a frequency band lower than the resonant frequency of a Helmholtz resonator. Thus, sound pressure in a low-frequency band equal to or lower than the resonant frequency of the Helmholtz resonator can be emphasized and the emphasized sound pressure can be given to the ear.

Abstract: A vibration generating device includes a stationary body including a bottom surface, a movable body disposed in an upper space of the bottom surface, and an elastic support disposed between the stationary and movable bodies and configured to support the movable body to be vibratable forward and backward to the stationary body. The elastic support includes a fixed portion fixed to the bottom surface, an upright portion extending upward from the fixed portion, an elastically deformable portion extending from the upright portion leftward and rightward, and a movable-body-attaching portion that extends from the elastically deformable portion and to which the movable body is attached. The elastic support includes a projection extending from the upright portion leftward and rightward at a position different from a position at which the elastically deformable portion extends from the upright portion leftward and rightward. A buffer is included between the projection and the stationary body.

Abstract: A vibration generating device includes a fixed case; a movable body disposed inside the fixed case; a support member configured to support the movable body with respect to the fixed case such that the movable body is configured to vibrate along a first direction; and a coil attached to the fixed case. The movable body includes a magnetic field generator configured to generate a magnetic field along a second direction perpendicular to the first direction, and a movable case configured to accommodate the magnetic field generator. A plurality of magnetic members including a permanent magnet constitute the magnetic field generator. The plurality of magnetic members are accommodated in the movable case such that the plurality of magnetic members are stacked in the first direction and are not movable relative to each other. A plurality of movable case members separable in the first direction constitute the movable case.

Abstract: A current sensor has a chassis, a magnetism detection element, and a bus bar through which a current under measurement flows. The current sensor is mounted on a circuit board in a state in which the chassis is inserted into an opening formed in the circuit board with current paths provided on a mounting surface and the bus bar is connected to the current paths. The bus bar has an incorporation portion placed in the interior of the chassis as well as externally connected portions extending from both ends of the incorporation portion, one from each side, toward the outside of the chassis. The externally connected portions are positioned above the bottom surface of the chassis in the up-down direction. The incorporation portion has an underneath portion positioned below the externally connected portions in the up-down direction.

Abstract: A movement mechanism includes: a case; a moving portion movable with respect to the case; and a support member that links the case and moving portion together and supports the moving portion so as to be movable with respect to the case. The support member has a plurality of pairs of first support portions and a plurality of pairs of second support portions, each of which is elastically deformable, has a plate-like shape, and extends between the case and the moving portion. The first support portions and second support portions are respectively placed on a first side and a second side in a moving direction of the moving portion so as to be symmetric with respect to the moving portion in plan view.
