Abstract: A sound reproduction device of the present disclosure includes a detection device that detects an object in a detecting area, and a superdirective speaker that can output a sound. In the superdirective speaker, directivity is set for the detecting area. When the detection device detects the object in the detecting area, the superdirective speaker outputs a sound to the detecting area.

Abstract: A speech output system includes a directional loudspeaker configured to produce a speech output directed to at least one audible area. The at least one audible area is defined by at least one of a presence area of a customer or a selling space as a unit in a premise in which a plurality of kinds of products are displayed. A control system is configured to control the speech output system. The control system is configured to cause the directional loudspeaker to produce a speech output of product information regarding a target product based on supply information, the supply information being information which is acquired from a supply status management system and which represents a supply status of the target product.

Abstract: An inertial force sensor has a first sensor element, a second sensor element, a first signal processor, a second signal processor, and a power controller. The first sensor element converts a first inertial force to an electric signal, and the second sensor element converts a second inertial force to an electric signal. The first signal processor is connected to the first sensor element, and outputs a first inertial force value. The second signal processor is connected to the second sensor element, and outputs a second inertial force value. The power controller is connected to the first signal processor and the second signal processor, and changes power supplied to the second signal processor based on the first inertial force value.

Abstract: A driver apparatus includes a vibrator and a drive circuit configured to input a drive signal to the vibrator to vibrate the vibrator. The drive circuit includes an output amplifier configured to output the drive signal to the vibrator based on a monitor signal, a power supply unit configured to supply a power supply voltage, and a power supply voltage controller configured to control the power supply voltage and to supply the controlled power supply voltage to the output amplifies. This driver apparatus can increase amplitude of the vibration of the vibrator, and can increase detection sensitivity to a physical quantity detection apparatus including the driver apparatus.
