| Zusammenfassung: | The invention discloses an earth wire balancing device and an earth wire balancing method for an externally connected device. The earth wire balancing device is arranged on the externally connected device and balances an earth wire of the externally connected device and an earth wire of a host machine when the externally connected device is connected to the host machine to be used so that the performance of the externally connected device is more stable. The earth wire balancing device for the externally connected device comprises a first metal sheet and a matching circuit, wherein the first metal sheet is connected to an earth wire signal pin of the externally connected device to form an earth wire structure of the externally connected device; and a matching network is designed on the basis of the wireless transmission performance of an antenna of the externally connected device and is connected between a metal shell and the first metal sheet. |
