External antenna device, antenna switch device and terminal equipment

Abstract

The invention discloses an external antenna device which comprises an external antenna and an audio plug, wherein the audio plug is connected with the external antenna and is used for controlling disconnection of an internal antenna and a receiver when an audio socket which is connected with the internal antenna and the receiver is plugged, so that the external antenna is connected with the receiver through match of the audio socket and the audio plug. The invention further discloses an antenna switch device which comprises the internal antenna and the receiver, and further comprises the audio socket, wherein the internal antenna is connected with the receiver through the audio socket. When the audio plug of the external antenna is plugged into the audio socket, the audio socket controls disconnection of the internal antenna and the receiver so that the external is connected with the receiver through the match of the audio socket and the audio plug. The invention further discloses terminal equipment comprising the antenna switch device. An electrical characteristic of the audio socket is utilized, and on condition of not increasing extra cost, physical switch of the internal antenna and the external antenna in the terminal equipment is achieved.

Description

technical field [0001] The invention relates to the technical fields of computer and communication, in particular to an external antenna device, an antenna switching device and terminal equipment. Background technique [0002] At present, with the development of communication technology and the popularization of smart phones, various mobile phones have increasingly rich functions. There are more and more mobile phones that implement CMMB (digital TV) functions in TD-SCDMA or WCDMA mobile phones, and because the frequency of CMMB is lower than that of TD-SCDMA or WCDMA, the external telescopic antenna is generally used as the antenna of CMMB, but Because of inconvenient use and new demands such as stylish appearance. Some mobile phones with CMMB built-in antennas have also begun to appear, but the built-in antennas still cannot achieve good performance. In places where the receiving signal is not good, users still hope to use the whip antenna to ensure the receiving performa...
