摘要: A vehicle approach notifying device for notifying the approach of a vehicle by causing a loudspeaker to output a warning sound includes: a storage that stores a predetermined threshold of sound pressure; and a controller that: (i) causes a loudspeaker disposed outside a cabin of the vehicle to output the warning sound at a first sound pressure determined in accordance with a speed of the vehicle when a sound pressure of the warning sound acquired by a microphone disposed outside the vehicle is less than or equal to the predetermined threshold; and (ii) causes the loudspeaker to output the warning sound at a sound pressure lower than the first sound pressure when the sound pressure of the warning sound acquired by the microphone exceeds the predetermined threshold.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: A signal processing device includes: an obtainer that obtains sound data; a pitch controller that controls pitch of the sound data obtained to increase the pitch by a factor of n (a real number greater than 1); an extractor that extracts frequency components of at least 20 kHz which are included in the sound data whose pitch is controlled; an adder that adds the frequency components extracted to the sound data obtained; and an outputter that outputs sound data to which the frequency components extracted are added.
