Abstract
A radio module detachably connects to a cellular telephone. The cellular telephone has a casing, a control circuit installed within the casing, a keypad electrically connected to the control circuit, and an external interface. The control circuit controls the operations of the cellular telephone. The keypad enables a user to direct the control circuit. The external interface has first contacts and an external connector with the first contacts electrically connected to the control circuit. The external connector detachably connects to a corresponding device. The radio module has a housing, a radio circuit installed within the housing, and a port. The port has a plurality of second contacts and a cellphone connector. The second contacts are electrically connected to the radio circuit. The cellphone connector detachably connects to the external connector of the cellular telephone. When the external connector of the cellular telephone is connected to the cellphone connector of the radio module, the first contacts are electrically connected to the second contacts, enabling the control circuit to send control signals to the radio circuit to control operations of the radio circuit. The user uses the keypad to direct the control circuit to generate the control signals, and the radio module enables the user to listen to broadcast radio programs according to the control signals.
