静电石墨烯扬声器

Electrostatic Graphene Loudspeaker

Qin Zhou, A. Zettl

摘要:

石墨烯具有极低的质量密度和高机械强度,这是高效宽频率响应静电音频扬声器设计的关键品质。低质量确保良好的高频响应,而高强度允许有效的低频响应所需的相对较大的独立振膜。在这里,我们报告的小型化石墨烯为基础的静电音频换能器的建设和测试。扬声器/耳机在设计和操作上都很简单,在整个音频频率范围(20 HZ-20 kHz)内具有出色的频率响应,性能与市售音频耳机相当或超过市售音频耳机。

英文摘要:

Graphene has extremely low mass density and high mechanical strength, key qualities for efficient wide-frequency-response electrostatic audio speaker design. Low mass ensures good high frequency response, while high strength allows for relatively large free-standing diaphragms necessary for effective low frequency response. Here we report on construction and testing of a miniaturized graphene-based electrostatic audio transducer. The speaker/earphone is straightforward in design and operation and has excellent frequency response across the entire audio frequency range (20HZ - 20kHz), with performance matching or surpassing commercially available audio earphones.
