| 摘要 |
The present invention provides a vibration detector device (1) suitable for use as a cochlear implant (12). The detector device (1) comprises a substrate (2) formed and arranged for supporting a plurality of resonator bars (4). The resonator bars (4) are of a uniform length and are supported at each end (6, 8) by the substrate material (2). Each of the resonator bars (4) has a distinct resonant frequency characteristic and is arranged with a piezoelectric generator to generate a signal in response to receiving a vibration which causes the resonator bar (4) to vibrate at its resonant frequency.
