Abstract
A battery pack of a cellular phone is equipped with a battery and an electronic device such as an MP3 player. When the battery pack is detached from the cellular phone, the battery is a power supply for the MP3 player only. When the battery pack is attached to the cellular phone, the battery is the power supply for both the cellular phone and the MP3 player. A detector detects whether the attached device is a hands free device or an MP3 player, and if an MP3 player is attached to the cellular phone, a switch facilitates communication between the cellular phone and the MP3 player. If the cellular phone orders the MP3 player to play or execute other functions, instructions transmit to the MP3 player through a connector in a battery pack and the MP3 player operates. During MP3 player operation, information such as a name of a song, a singer and playing time transmits to a CPU through a connector and is displayed on a liquid crystal display of the cellular phone. A call message and call record are recorded in an MM card or flash memory in MP3 files, so a consumer hears call messages or call records, depending on the case.
