Ultrasonic - 來自歐洲，專注於超聲波（指向性喇叭）發聲技術的音訊大廠
與普通喇叭相異的是，為了製造能夠集中的高頻率，指向性喇叭必須用另一種方式來產生波形，在目前所廣用的技術中，最常使用由石英等晶體製作的能量發射器，這種以晶體接收電流所製成的發射器能夠產生超過人類聽覺範圍的頻率，也就是超越 20 kHz 的 “超聲波 Ultrasound” 。在同一時間使用由眾多這種晶體所製成的發射器，形成陣列後，便可增強其單一微弱的能量，使其真正成為一個 “聲音束 Sound Beam” 。
此聲音束藉由空氣傳輸，在打到物體時，能夠立即調變成人耳可聽到的頻率範圍，國外已有諸多博物館、車站、美術館以及藝廊等等場所使用指向性喇叭技術。
高度控制聲音的來源及走向，即便是在公開場域，只播放給特定區域也不再是不可能的事。
背後的原理以及技術相當複雜，不過， Ultrasonic 為我們提供了最為簡易且負擔得起的方式使用這項技術 - Ultrasonic Acouspade Classic™ 指向性喇叭！
