ABSTRACT:
A mass excited acoustic device (1100) includes a soundboard (1102), a pedestal (1104) and a transducer (300). The soundboard (1102) has a predetermined resonance frequency and couples motional energy to a device user. The pedestal (1104) includes a platform (1106) formed for mounting a transducer (300), and a foot (1108). The platform (1106) and foot have an axis extending centrally therethrough. The foot (1108) is contiguous to the platform (1106) and to the soundboard (1102), and is substantially smaller in size than the platform (1106) and separates the platform (1106) from the soundboard (1102). The transducer (300) is coupled to the platform (1106) about the axis and converts an electrical input signal into motional energy generated in a direction parallel to the axis. The motional energy is delivered to the soundboard (1102) through the foot (1108) without substantially modifying the resonance frequency of the soundboard (1102).
