  • 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.

  • Publication number: 20090052693
    Abstract: A sound reproducing apparatus is structured to use a first dividing circuit and a determining circuit to analyze a frequency characteristic of an inputted signal and to output a signal adjusted by a first adjusting circuit to have a prescribed frequency characteristic by a switching by a switch circuit. Thus, when signals having different frequency characteristics are inputted, frequency characteristics of the input signals can be automatically adjusted without using an external signal and channels having different frequency characteristics can be reproduced by a single system to provide good speaker-reproduced sound.
