First Claim
1. An electronic apparatus comprising:
- a main body;
a speaker unit detachably connected to said main body, said speaker unit having a speaker, a first wireless communication unit, and a D/A converter;
a second wireless communication unit which transmits an audio digital signal to the first wireless communication unit over a wireless cannel;
a detector which detects whether or not said speaker unit is installed in said main body; and
a controller which actuates said second wireless communication unit to transmit the audio digital signal to the first wireless communication unit when said detector detects that said speaker unit is not installed in said main body, wherein the D/A converter converts the audio digital signal received by the first communication unit to an audio analog signal, and the speaker outputs sound on the basis of the audio analog signal.

Abstract
An electronic apparatus has a main body, and a speaker unit detachably mounted to the main body. The speaker unit includes a speaker, a first wireless communication unit, and a D/A converter. The electronic apparatus also has a second wireless communication unit which transmits an audio digital signal to the first communication unit over a wireless cannel, a detector which detects whether or not the speaker unit is installed in said main body, and a controller which actuates the second wireless communication for transmitting the audio digital signal to the first communication unit when the detector detects that said speaker unit is not installed in said main body. The D/A converter converts the audio digital signal received by the first communication unit to an audio analog signal, and the speaker outputs sound on the basis of the audio analog signal.
