    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.

  • Publication number: 20190158970
    Abstract: Provided is a sound reproduction device that can accurately adjust a warning sound output from a loudspeaker. The sound reproduction device includes a loudspeaker unit including a loudspeaker and an identifier that identifies a characteristic of the loudspeaker and an amplifier unit that amplifies a signal corresponding to a sound output from the loudspeaker. The amplifier unit includes an amplifier that amplifies the signal input from a sound source and outputs the amplified signal to the loudspeaker, a determination unit, and an amplification degree adjuster. When the loudspeaker unit and the amplifier unit are connected to each other, the determination unit determines the characteristic of the loudspeaker from the identifier of the connected loudspeaker unit. The amplification degree adjuster adjusts the amplification degree of the signal output from the amplifier according to the characteristic of the loudspeaker determined by the determination unit.

  • Patent number: 9914391
    Abstract: A vehicle proximity notification apparatus has first and second loudspeakers which output warning sound notifying proximity of a vehicle to an outside, and an adjusting unit. The adjusting unit adjusts the sound output from the first loudspeaker so that a sound collecting signal, which is obtained when the second loudspeaker collects the sound output from the first loudspeaker, coincides with a reference signal, in a state in which the first loudspeaker functions as a sound outputting element and the second loudspeaker functions as a sound collecting element. In addition, the adjusting unit adjusts the sound output from the second loudspeaker so that a sound collecting signal, which is obtained when the first loudspeaker collects the sound output from the second loudspeaker, coincides with a reference signal, in a state in which the second loudspeaker functions as a sound outputting element and the first loudspeaker functions as the sound collecting element.

  • Patent number: 9860638
    Abstract: An inspection signal generator of an acoustic device outputs a first inspection signal. An amplifier receives a first reference signal, and outputs a second inspection signal according to the first inspection signal. A first detector is electrically connected to an output side of the amplifier, and outputs a first detection signal based on the second inspection signal. The first detector is electrically connected to the output side of the amplifier, and outputs the first detection signal based on the second inspection signal. A determiner compares a first detection signal output from the first detector with a preset determination reference signal so as to detect electrical abnormality between a ground terminal and an output terminal electrically connected to the output side of the amplifier.

  • Patent number: 9743186
    Abstract: Provided is a sound reproduction device including a loudspeaker and a superdirective speaker. The loudspeaker is configured so that a sound pressure of audible sound produced therefrom decreases as the sound travels farther away from the loudspeaker. The superdirective speaker is configured so that a sound pressure of audible sound produced therefrom has a peak at a predetermined distance from the superdirective speaker, and is configured to use an ultrasonic wave as a carrier wave. The loudspeaker and the superdirective speaker are positioned such that a loudspeaker sound field of the audible sound produced from the loudspeaker and a superdirective speaker sound field of the audible sound produced from the superdirective speaker overlap with each other at a position of a listener.
