super-directional-speaker
v9 v10 7 7 Super directional ultrasonic speaker sends the sound only straight out, meaning you can hear the audio only if you are right in front of the speaker. To feel this effect clearly, I made the remote controlled base so that the speaker can face different directions.[[BR]] 8 8 9 10 11 12 9 [[Image(s-SDspeaker.jpg)]] 13 10 14 筐体はSDプリンタで出力しました。使用したフィラメント素材はABSです。 11 Arduino Esplora is used as console.[[BR]] 12 13 I used 3D printer to make the base to hold the speaker kit in place.[[BR]] 15 14 16 15 使用した部品のリストです。(スイッチサイエンスで入手可能なものにはリンクがあります。)
