    Abstract: Provided is a vehicle approach notification device that can easily output a warning sound in which a discomfort feeling brought to an occupant is reduced while ensuring a necessary sound pressure. A vehicle approach notification device includes: a sound source; first and second amplifiers; a first speaker system including a first speaker and a second speaker that outputs a sound having an opposite phase to a sound output from the first speaker; and a second speaker system including a third speaker that outputs a sound having a same phase as the sound output from the first speaker and a fourth speaker that outputs a sound having an opposite phase to the sound output from the third speaker, wherein the first speaker system and the second speaker system are disposed so that the first speaker and the third speaker are located closer to a longitudinal center plane of the vehicle than the second speaker and the fourth speaker.

    Abstract: A proximity alarm device includes a control unit, an amplifying unit, an output terminal, a ground terminal, a detection unit, and a determining apparatus. The control unit receives an input of a referencing signal. An output of the control unit is electrically connected to the amplifying unit. An output of the amplifying unit is electrically connected to an output terminal. The ground terminal is electrically connected to a ground. The output of the amplifying unit is electrically connected to the detection unit. An output of the detection unit is electrically connected to the determining apparatus. Then, the determining apparatus compares a detection signal detected by the detection unit and a determination reference signal with each other.
