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 designs the technical field of active noise reduction and communication, and specifically relates to a cloud service-based active noise reduction headset design system and method. Background technique [0002] When active noise reduction headphones are mass-produced, the noise reduction parameters of the headphones need to be adjusted. Because the acoustic characteristics of each earphone are different, if the same set of noise reduction parameters is used, the noise reduction performance of different headphones will be different, leading to mass production The noise-cancelling headphones of the company have the problem of poor noise-cancelling performance. The existing method to solve this problem is to adjust the gain under the premise of fixing other noise reduction parameters of the earphone to achieve the optimal noise reduction effect without howling. This on-line design method of active noise reduction headphones that only adjusts the ...
