The multipack includes an antenna for receiving an over-the-air broadcast signal; A TV tuner or radio tuner for selecting a required frequency from the radio waves received at the antenna and amplifying the signal to convert the signal into a baseband signal; An NTSC decoder for converting a baseband signal output from the TV tuner to a television system; An audio amplifier for amplifying an audio signal output from the TV tuner and / or the radio tuner; An audio output unit configured to output the amplified audio signal; And a battery cell,

The main body includes a graphics controller for processing data according to the LCD screen structure of the output signal of the NTSC decoder; An LCD panel driven by a signal output from the graphic controller; A power supply unit supplying power through the battery cell; And a control unit controlling the tuner and the NTSC decoder.

The connector serves to electrically connect the main body and the multipack. That is, power is supplied from the multipack to the main body through the connector, an analog television broadcast signal, a radio broadcast signal, and the like are transmitted, and serves as an intermediary for transmitting and receiving a signal from the controller of the main body.

The multipack has a broadcast signal reception function added to a conventional battery pack.

The airwave broadcast signal refers to a television and radio (FM / AM) broadcast signal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the structure of a terminal according to the present invention, Figures 2 and 3 is a block diagram of a terminal according to an embodiment of the present invention.

As shown in FIG. 1, the terminal according to the present invention is composed of a main body 10 and a multipack 20 coupled to the main body 10.

The multipack includes a TV / FM reception circuit unit 21, a battery unit 23, a male connector 25, a speaker 24, and a TV / FM selection terminal 22.

In addition, the main body 10 includes a female connector 12 and an LCD panel 11.

The multipack 20 and the main body 10 are electrically coupled by coupling the male connector 25 of the multipack and the female connector 12 of the main body.

The TV / FM selection terminal 22 is used to select one of a TV broadcast signal and a radio broadcast signal.

The main body 10 and the multipack 20 of the terminal will be described in more detail with reference to FIGS. 2 and 3.
