<P>PROBLEM TO BE SOLVED: To provide a speaker device capable of properly controlling wireless reception field intensity. <P>SOLUTION: In the speaker device 3A, a reception antenna Aj receives wireless signals to be transmitted from a reproducing device 2, and an RF receiving section outputs an analog field intensity signal corresponding to the wireless reception field intensity to a light emission control means. Then, the light emission control means controls the operation state of an LED 32A as a state where changes are made continuously depending on the wireless reception field intensity on the basis of the analog field intensity signal. As described above, since the operation state of the LED 32A is continuously changed depending on the wireless reception field intensity, the LED 32A can be operated in a state corresponding to a small change in the reception field intensity, even if it is small, and a user can properly recognize the reception field intensity. <P>COPYRIGHT: (C)2008,JPO&INPIT |
