Thanko has recently released a household speaker that is automatically activated when its sensor detects that someone is nearby. A micro SD card is inserted into the speaker so that any music files, educational content, alarm noise, etc. copied from your computer can be played.
Because of its motion detector, the speaker can be used in various situations and can be customized to meet your own needs.
For example, when placed on the kitchen wall, you can repeat after the phrases and words spoken in Japanese audio lessons when you’re doing the dishes.
The speaker is compact and can be attached anywhere using screws or tape, and works on batteries. Costs 3,180 yen (tax included).
