扬声器是把音频电流转换为声音的电声器件。振动板(俗称纸盆)是扬声器的重要组成元件。纸盆,故名思义,过去多用纸浆制造。它的比模量小,易吸潮变形,往往引起失真。为了得到高保真度的声学性能,可用天然纤维或合成纤维的复合材料来制造,特别是用碳纤维增强塑料(CFRP)更能获得满意的音响效果。这与碳纤维兼备多种性能密切有关。
Speakers are electro-acoustic devices that convert audio current into sound. Vibrating plate (commonly known as cone) is an important component of the speaker. Paper basin, the name suggests, in the past with more pulp manufacturing. Its specific modulus is small, easy to absorb moisture deformation, often cause distortion. In order to obtain high fidelity acoustic performance, natural fiber or synthetic fiber composite materials can be used to manufacture, especially with carbon fiber reinforced plastics (CFRP) more satisfactory sound effects. This is closely related to the multiple properties of carbon fiber.
