Audio listening device for the hearing impaired |
摘要 |
An audio listening device includes a circuit for amplifying sound source signals and a mechanism including a bone conduction vibrator transforming an output signal of the amplifying circuit into a vibration. A vibration source transforms the output of the amplifying circuit into a first magnetic field and vibration. A vibration generating unit generates a second magnetic field for the vibration source to vibrate upwards and downwards due to attraction and repulsion processes of the first and second magnetic fields. A damper is connected to the vibration source to arouse air conduction hearing due to the vibration of the vibration source. A vibration plate is connected to the vibration source to arouse a bone conduction hearing due to the vibration of the vibration source. A vibration transmission unit transmits the bone conduction hearing and air conduction hearing to the hearing impaired.
