Theremin 是一世界上第一件電子樂器,不用接觸它都可以遙控它發出不同的音調,曾盛極一時,被用於演奏荷李活電影的配樂,旋律優美。ThinkGeek 推出的 Theremin Mini Kit 把這項神奇的樂器縮小了,它以 4 粒 AA 電池操作,尺寸大概為 3.15 x 3.15 x 4.72 吋,使它更可愛,更容易收納在家中,讓大家都更有機會感受一下它的神奇。
要製造音樂,只需在 Theremin 天線前位置揚手,天線附近的一個區域內會產生電磁波,一個位置的電磁波被不同的手勢中斷,波的頻率會被改變,從而改變可聽見的音調旋律,演奏出音樂。有一些 Theremin 會有第二條天線控制音量和速度,但 Theremin Mini Kit 就沒有做到。
Theremin Mini Kit 十分容易裝嵌,這裝置內有日文說明書,但有網上有英文說明書,只售 USD $39.99,不易操作的,但如果懂得演奏它的話,奏出的音樂會十分動人和特別。
