Abstract: To make a notification to the driver so that the driver can distinguish or recognize the notification. A vehicle notification device (1a) inputs a first sweep signal whose frequency is changed in a predetermined frequency range, to a vibrator (4), calculates frequency characteristics of a vibration in the vehicle interior, detects a frequency range in which the signal level of vehicle-travel-time frequency characteristics is higher than the signal level of vehicle-stop-time frequency characteristics by a predetermined level amount or more, generates a second sweep signal whose frequency is changed in a range obtained by excluding the detected frequency range from the predetermined frequency range of the first sweep signal, and outputs the second sweep signal from the vibrator (4).

Abstract: A sound field measuring device (1) obtains frequency characteristics by collecting output sound outputted from a pair of speakers (101a, 101b) installed at a narrow interval. A low-pass filter (22a) extracts low-range components of a first measurement signal. A high-pass filter (22b) extracts mid/high-range components of a second measurement signal different from the first measurement signal. A combined signal generation unit (22c) generates a combined signal by combining the low-range components of the first measurement signal and the mid/high-range components of the second measurement signal. An external output unit (6) outputs the first measurement signal to an audio system (102). A microphone (7) collects the first measurement signal and the combined signal simultaneously outputted from the pair of speakers. A Fourier transform unit (13) obtains the frequency characteristics of a sound field by Fourier transforming the signals collected.

Abstract: The present invention provides a vibration audio system for transmitting an audio signal outputted from a sound source to a listener in the form of vibration while reducing output level of the signal and power consumption. The system includes an envelope detection unit (204) for detecting an envelope signal of the audio signal outputted from a sound source, a vibration transmission member for allowing the listener to perceive vibration of a low-frequency sound outputted from a low-frequency output speaker that outputs audio signals, and a frequency conversion unit (205) for generating an audio signal frequency-converted on the basis of resonant frequencies by multiplying the envelope signal by sine waves having the same frequencies as resonance frequencies obtained from an impulse response of the low-frequency output speaker disposed in the vibration transmission member. The audio signal frequency-converted by the frequency conversion unit (205) is outputted from the low-frequency output speaker.
