Embodiment Construction

[0031] 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.

[0032] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a sound production device. The sound production device comprises an outer shell, and a vibration system and a magnetic circuit system connected with the outer shell, wherein the magnetic circuit system comprises a magnetic conductive yoke, the magnetic conductive yoke is provided with a magnetic conductive body and a connecting flange, the magnetic conductive body faces a vibrating diaphragm of the vibrating system, the connecting flange is formed by bending the magnetic conductive body towards one side where the vibrating diaphragm is located, and a plurality of air holes are formed in the connecting flange; and a leakage opening is formed between the outer shell and the magnetic conductive body, and the connecting flange completely covers the leakage opening. According to the sound production device, the reject ratio of products can be reduced.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a sound generating device. Background technique [0002] In order to realize the full-filling technology of the rear acoustic cavity of the sound-generating device in the related art, a mesh cloth is generally arranged at the leakage port of the sound-generating device, and the mesh cloth and the shell of the sound-generating device are integrally injection-molded or fixed by bonding. [0003] However, because the shape of the mesh itself is difficult to maintain, it is easy to cause misalignment between the mesh and the leakage port during integral injection molding or bonding, which increases the defective rate of the product. Contents of the invention [0004] The main purpose of the present invention is to provide a sound generating device, aiming at reducing the defective rate of products. [0005] In order to achieve the above object, the sound generating...
