| 摘要 |
<p>This invention is a direct hearing system (100) for providing an ultrasonic signal to a portion of the human ear. The direct drive hearing system (100) includes an ultrasonic direct device. The device includes a housing (110) with at least one coil (112) coupled to the housing (110). Inside the housing (110) is a magnet (116), which vibrates at an ultrasonic resonant frequency in direct response to an externally generated electric signal through the at least one coil (112). A biasing mechanism (118), which supports the magnet (116) within the housing (110), is also provided. The magnet (116) is free to move within the housing (110) subject to the retention provided by the biasing mechanism (118). The hearing system (100) is partially or totalling implanted.</p> |
