しまう場合も起り得る。 However, since the above-mentioned device generates a sense of presence through the auditory sensation from the speaker and the bodily sensation from the vibrating body, consistency with the auditory sensation is important. For example, if different speakers have different reproduction frequency characteristics, the sense of presence will be It is also possible that the sensation becomes weaker. In particular, when the above-mentioned acoustic vibration transmission device is applied to a passenger car, etc., the characteristics of the speakers installed at the front and rear of the passenger compartment generally differ depending on various conditions, so the speakers at the front and rear of the passenger compartment can be switched and separately installed. If the reproducing characteristics of the vibrating body are the same during a reproducing operation, there may be a mismatch between the auditory sensation and the bodily sensation, resulting in a decrease in the sense of presence.
