| 发明名称 | Bone conduction transducer with improved high frequency response | ||
| 摘要 | A bone conduction transducer comprising a first seismic mass and a second mass connected to each other by a first spring suspension, and where the first mass and the first spring suspension creates a first mechanical resonance f1 in the low frequency range, and that a second mechanical resonance f2 is created in the high frequency range by interaction between the second mass and a second spring compliance that is introduced between the second mass and the skull. | ||

| 主权项 | 1. A bone conduction transducer device comprising a first seismic mass and a second mass connected to each other by a first spring suspension with compliance, where a coil and magnetic circuits are integrated into the two masses and generate dynamic forces in air gaps formed between the first and second masses when a current is supplied to the coil, and where the first mass and the first spring suspension creates a first mechanical resonance in a low frequency range, wherein a second mechanical resonance is created in a high frequency range by interaction between the second mass and a second spring suspension with compliance that is introduced between the second mass and a load. | ||
