Abstract
Disclosed is a mobile terminal comprising: a terminal body having a touch screen; an audio jack mounted to one side of the terminal body, and connected to an audio output device; and an antenna device detachably mounted to the audio jack, wherein the antenna device includes: an antenna body implemented in the form of a rod having a predetermined length; a connector formed atone end of the antenna body so as to be inserted into the audio jack, and including one or more feeding terminals; and a touch tip provided at an end of the connector, and configured to manipulate the touch screen.
Claims21
A mobile terminal, comprising:
- a terminal body having a touch screen;
- and
- an audio jack provided on the terminal body, the audio jack configured to connect with an audio output device or an antenna device when the audio output device or the antenna device is alternatively coupled to the audio jack;
- wherein the antenna device includes:
- an antenna body,
- a connector provided at one end of the antenna body being prepared for insertion into the audio jack, the connector including at least one feeding terminal to transmit or receive a radio signal, and
- a touch tip provided at the connector, and the touch tip configured to manipulate the touch screen, and
- wherein the audio jack includes:
- a signal terminal to transmit the radio signal to the audio output device or to receive the radio signal from the audio output device when the audio output device is coupled to the audio jack, and
- a ground terminal to transmit the radio signal to the antenna device or to receive the radio signal from the antenna device when the antenna device is coupled to the audio jack, and
- wherein the connector includes an insulator configured to insulate part of the connector for preventing an electrical connection to the signal terminal.

A mobile terminal comprising:
- a terminal body having a touch screen;
- an audio jack on the terminal body to electrically connect to an audio device, the audio jack including a plurality of terminals;
- an antenna device to wireless receive a broadcast signal, the antenna device including an antenna body, a plurality of telescopic rods to extend from the antenna body, a connector having a plurality of feeding terminals to electrically contact the audio jack when the antenna device is separately electrically connected to the audio jack, and a touch tip coupled to the connector to provide a user input via the touch screen when the antenna device is electrically disconnected from the audio jack;
- and
- a recognition device to determine whether the audio device is electrically connected to the audio jack and to determine whether the antenna device is electrically connected to the audio jack, wherein the audio jack provides an audio signal to the audio device when the audio device is electrically connected to the audio jack, and the audio jack to receive the broadcast signal from the antenna device when the antenna device is electrically connected to the audio jack,
- wherein the recognition device includes:
- a first comparator to output a first comparison value based on a comparison of a first preset voltage and a voltage at a first one of the terminals of the audio jack, and
- a second comparator to output a second comparison value based on a comparison of a second preset voltage and the voltage at the first one of the terminals of the audio jack, wherein the second preset voltage value is higher than the first preset voltage,
- wherein the recognition device determines whether the audio device is electrically connected to the audio jack and determines whether the antenna device is electrically connected to the audio jack based on the first comparison value and the second comparison value.
