    • An acoustic system includes a sound-electro converting device, a electro-wave converting device, and a sound wave generator. The electro-wave converting device is connected to the sound-electro converting device. The sound wave generator is spaced from the electro-wave converting device and includes a carbon nanotube structure. The sound-electro converting device converts a sound pressure to an electrical signal and transmits the electrical signal to the electro-wave converting device. The electro-wave converting device emits an electromagnetic signal corresponding to the electrical signal and transmits the electromagnetic signal to the carbon nanotube structure. The carbon nanotube structure converts the electromagnetic signal into heat, and the heat transfers to a medium causing a thermoacoustic effect.
    • 声学系统包括声电转换装置,电波转换装置和声波发生器。 电波转换装置连接到声电转换装置。 声波发生器与电波转换装置间隔开并且包括碳纳米管结构。 声电转换装置将声压转换为电信号,并将电信号发送到电波转换装置。 电波转换装置发射对应于电信号的电磁信号,并将电磁信号发送到碳纳米管结构。 碳纳米管结构将电磁信号转换为热,并将热量转移到导致热声效应的介质。
