Title:
SOUND PRODUCTION DEVICE, CALIBRATION METHOD FOR SOUND PRODUCTION DEVICE, AND SOUND PRODUCTION MODULE
Document Type and Number:
WIPO Patent Application WO/2023/082721
Kind Code:
A1
Abstract:
Disclosed are a sound production device, a calibration method for a sound production device, and a sound production module. The sound production device comprises two sound production modules; each sound production module comprises a cavity, a sound production unit, and an adjusting device; the sound production unit is arranged in the cavity and partitions the cavity into a front cavity and a rear cavity; the adjusting device comprises an adjusting plate and a driving part; one end of the adjusting plate is rotatably mounted on an inner wall of the rear cavity; and the driving part drives the adjusting plate to move so as to adjust the effective volume of the rear cavity. In the sound production device of the present invention, the peak frequency of one of the sound production modules can be adjusted correspondingly by changing the position of the adjusting plate in the sound production module, so as to cause a difference between frequency response parameters of the two sound production modules to be within a preset range, such that the two sound production modules are more consistent, thereby achieving a good far-field sound elimination effect.
