Kind Code:
A1
Abstract:
Provided are: an exciter-equipped glass vibration plate in which an exciter can be mechanically fixed to the vibration plate without loss of low-sound reproducibility; and a vehicle vibration plate and a building vibration plate each comprising the same. An exciter-equipped glass vibration plate according to the present invention comprises: a glass vibration plate; an exciter that excites a mass body which is supported via a spring material, so as to generate vibrations; and a coupling part which mechanically couples the glass vibration plate and the exciter and transmits vibrations from the exciter to the glass vibration plate. The expression given here is satisfied, where k is a spring constant (N/m) between the glass vibration plate and the exciter, and m is the mass (kg) of a vibration unit of a mass body.
