摘要 |
A telephone system is provided with a receiver equipped to enable a hearing-impair person to receive a telephone call through bone-conduction and air-conduction hearing. Such a receiver comprises a frame supporting a main vibration source including a cylindrical bobbin and a voice coil wound around the bobbin to convert a voice signal into a variation of a magnetic field; a vibration generator including a yoke arranged inside a lower portion of the bobbin, an electromagnet arranged on the yoke to create a gap with the bobbin, and an upper plate arranged on the electromagnet to support the electromagnet; an auxiliary vibration source including an air-conduction vibrator arousing air-conduction hearing and a bone-conduction vibrator arousing a bone-conduction hearing; and a vibration transmitter arranged to transmit vibrations from the main vibration source and the bone-conduction vibrator of the auxiliary vibration source to a transmission portion where a bone-conduction hearing transmission is selected for bone-conduction hearing. |
