Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0046] It should be noted that if there are directional indications involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture. If the specific posture changes , then the directional indication changes accordingly.

[0047] In addition, if there are descriptions involving "first", "second" and so o...

Abstract

The invention discloses a sound production device, a calibration method of the sound production device and sound production units, the sound production device comprises two sound production units, each sound production unit comprises a cavity, a sound production single body and an adjusting device, the sound production single body is arranged in the cavity and divides 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 one 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. According to the sound production device, the position of the adjusting plate in one sound production unit is changed, so that the peak frequency of the sound production unit is correspondingly adjusted, the difference value between the frequency response parameters of the two sound production units is within the preset range, the consistency of the two sound production units is better, and the good far-field noise elimination effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sounding devices, in particular to a sounding device, a calibration method of the sounding device and a sounding unit. Background technique [0002] At present, there are more and more VR and AR products on the market, and people have higher and higher requirements for privacy on the basis of satisfying daily use. The products currently on the market already have the commonly used far-field noise cancellation scheme of a single sounding unit and the far-field noise cancellation scheme of a double sounding unit. The dual sound unit will gradually become the mainstream due to the flexibility of combination and the variety of functions that can be realized. But for dual sounding units, the difference of the sounding units is inevitable, and the consistency of the sounding units will directly affect the far-field noise cancellation. Contents of the invention [0003] The main purpose of the present invent...
