Provided is a vibration-frequency designing method based on music frequency. The method comprises the following steps: S1: presetting a set of quantization modules which comprises a personalized input quantization module, a music feature quantization module and a vibration effect quantization module; S2: inputting a user personalization parameter, and obtaining a specific quantization value of personalized input through the personalized input quantization module; S3: extracting a music feature of a music signal, and obtaining a specific quantization value of the music feature through the music feature quantization module; S4: carrying out quantization calculation, calculating same according to a formula, and obtaining a relative value of a vibration effect frequency; S5: mapping the relative value of the vibration effect frequency through the vibration effect quantization module to obtain an absolute value of the vibration effect frequency; and S6: broadcasting the vibration by a motor on the basis of the absolute value of the vibration effect frequency. The vibration-frequency designing method realizes perfect conversion from an audio music frequency to a tactile vibration frequency, and provides designers or users with an efficient and rich tactile experience.
