Abstract

The invention relates to the technical fields of active noise reduction and communication, in particular to a cloud service-based active noise reduction earphone design system and method. According tothe cloud service-based active noise reduction earphone design system and method, local active noise reduction design systems and a cloud server are included, wherein each local active noise reduction design system comprises an earphone wearing device, a data acquisition device, a to-be-designed noise reduction earphone and a monitoring device. Compared with an existing active noise reduction on-line design system, the system and method have the advantages that parameters of the noise reduction system can be designed on line according to the vocal cavity characteristic of each to-be-designedactive noise reduction earphone, all the active noise reduction earphones designed by adopting the system can achieve an excellent noise reduction effect, and it can be guaranteed that the noise reduction performances of the designed active noise reduction earphones have the good consistency; and meanwhile, by adopting the cloud server to design the noise reduction parameters, the computing speedis increased, the computing performance is improved, the burden of a user side is reduced, the requirement of serving design of multiple noise reduction systems simultaneously is met.

Description

technical field [0001] The invention relates to the technical field of design active noise reduction and communication, and specifically relates to a cloud service-based active noise reduction earphone design system and method. Background technique [0002] During mass production of active noise-cancelling earphones, the noise-cancelling parameters of the earphones need to be adjusted. Due to the differences in the acoustic characteristics of each earphone, if the same set of noise-cancelling parameters is used, the noise-cancelling performance of different earphones will be different, resulting in mass production. The noise-canceling headphones of the company have the problem of poor consistency in noise-canceling performance. The existing method to solve this problem is to adjust the gain on the premise of fixing other noise reduction parameters of the earphone to achieve the optimal noise reduction effect without howling. This online design method of active noise reducti...
