Claims

[Scope of utility model registration request]

(1) The main body case 2 includes an amplification means 3 for amplifying a signal input from the outside, a power supply 4 for supplying power to the amplification means 3, and a speaker 5 for reproducing the signal amplified by the amplification means 3. This speaker device has a switching means 6 that controls the on/off of energization to the amplifying means 3 in conjunction with the movement of the speaker 5, and the speaker 5 can be freely stored and pulled out from the main body case 2, and the speaker device A speaker device in which a switching means 6 can be turned on in a state where a speaker 5 is exposed from at least a main body case 2 to a position where effective sound can be generated.

(2) The speaker device according to claim 1, wherein the switching means 6 is a reed switch 26 that is turned on and off by the approach and separation of the magnet 29 of the speaker 5.

(3) The speaker device according to claim 1, wherein the switching means 6 is an on/off switch that can be operated by pulling out the speaker 5 from the main body case 2.
