| 发明名称 | Personal hands-free accessory for mobile device | ||
| 摘要 | A hands-free accessory for a mobile device may include a microphone element, and a telecoil coupled with the microphone element in parallel. The microphone element and the telecoil are coupled with an output terminal of the hands-free device. The hands-free accessory may further include a capacitor coupled with the telecoil in series. The hands-free accessory may further include an ear speaker. The hands-free accessory may further include a first switch between the microphone element and the telecoil. Alternatively, the mobile device may include a second switch configured to control operation of the microphone element. When the first switch or the second switch is turned off/closed, the microphone element is not operated, and a signal corresponding to an electric current induced in the telecoil is input/transmitted to the mobile device. | ||
