Abstract: A speaker system includes a cushion body with which a person comes into contact when sitting therein, and a speaker, a front of which is covered by the cushion body. The cushion body includes: a three-dimensional mesh-like elastic part that is formed by a three-dimensionally entangled fiber and bears a load of the person; and a cover member that covers surroundings of the three-dimensional mesh-like elastic part. The cover member includes a first cover member that covers the part of the surroundings of the three-dimensional mesh-like elastic part located at the front of the speaker, and a second cover member that is a remainder of the cover member excluding the first cover member. The first cover member has a higher acoustic transmissivity than the second cover member.

Abstract: A vehicle proximity notification device that notifies proximity of a vehicle by causing a speaker disposed outside a vehicle interior of the vehicle to output a warning sound. The vehicle proximity notification device includes: a controller that, when a sound pressure of a sound collected by a microphone disposed outside the vehicle interior exceeds a first threshold, sets a sound pressure of the warning sound output by the speaker to a level lower than the sound pressure of the warning sound output by the speaker when the sound pressure of the sound collected by the microphone is lower than or equal to the first threshold.

Abstract: A vehicle approach notification system includes a filter; a notification sound controller which generates a signal corresponding to a notification sound for notifying of approaching of a vehicle, based on a sound signal obtained from a notification-sound sound source; and a setter which obtains vehicle information of the vehicle, and sets, according to the vehicle information, at least one of the notification-sound sound source to be used in generation of the notification sound, a filter property to be applied to the filter, or a control parameter to be applied to the notification sound controller in generation of the notification sound. The notification sound controller outputs the signal generated, through the filter to an exterior loudspeaker provided to the vehicle.

Abstract: A signal processing device for reproducing a musical piece from one or more loudspeakers and one or more actuators that are provided in a seat includes: an obtainer that obtains data of the musical piece; and an outputter that outputs an acoustic signal of a first frequency band included in the data of the musical piece to the one or more actuators, and outputs an acoustic signal of a frequency band excluding the first frequency band to the one or more loudspeakers, the frequency band being included in the data of the musical piece. The first frequency band is a band including a resonance frequency of the one or more actuators.
