Instead of being made on the face of the cone, it's made at literally billions of little independent points along this narrow column in the air, and so when I aim it towards you, what you hear is made right next to your ears.
コーンの面で作られるのではなく、 空気中に存在する何億と言うポイントが 柱状に伸びて音は作られていて、 耳に向けると 音は耳のすぐ側で作られています。
