Waterproof loudspeaker diaphragm and loudspeaker

Abstract

The invention discloses a waterproof loudspeaker diaphragm which comprises a diaphragm body (1) and is characterized in that the diaphragm body (1) is sequentially provided with a central part (2), a folding ring part (3) and a fixed part (4) from inside to outside, the central part (2) is provided with a vibrating plate (5) matched with the central part (2), and the top end of the folding ring part (3) is provided with a diaphragm carrying ring (6) arranged on the vibrating plate (5) in a sleeving mode. The top end of the fixed part (4) is provided with synthetic resin (7) connected with the diaphragm carrying ring (6). The invention has the beneficial effects that the cofferdam is formed at the edge of the folding ring part, the inner wall of the cofferdam is coated with glue, the inner wall of the cofferdam is attached to the outer edge of the front cover, and due to the flowability of the glue, the glue can be automatically converged downwards to prevent air holes, so the root of the inner wall of the cofferdam and the bottom of the outer edge of the front cover are reliably sealed.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a waterproof loudspeaker diaphragm and a loudspeaker. Background technique [0002] Loudspeaker is a very common electronic device in life, and is widely used in portable electronic devices such as MP3, mobile phone and tablet computer. In recent years, people's requirements for loudspeakers are not limited to having better acoustic performance, but also put forward higher requirements for the reliability of loudspeakers. [0003] The seal between the existing speaker front cover and the diaphragm is as follows: first, apply glue on the edge of the diaphragm; secondly, directly attach the front cover to the diaphragm; finally, after the glue is cured, a sealing layer is formed to seal the diaphragm and the front contact surface of the cover. The disadvantages are: the initial state of the glue is flowable, and the contact surface between the diaphragm and the front cover i...

AI Technical Summary

Problems solved by technology

The disadvantages are: the initial state of the glue is flowable, and the contact surface between the diaphragm and the front cover is flat, so it is difficult to control the trajectory of the glue, and the positioning of the diaphragm is difficult, and it is easy to stick crookedly; secondly, when After the glue is solidified, due to the fluidity of the glue, the solidified glue between the front cover and the diaphragm inevitably has pores or even uneven distribution of the glue. When encountering a humid environment, water vapor will enter the inside of the front cover through the pores. Then it is attached to the diaphragm, which affects the function of the diaphragm; the traditional speaker distribution method cannot meet the existing playback requirements. In order to meet the speaker requirements of different electronic devices, the method of increasing the playback volume of a single speaker seriously increases the The work burden of a single speaker reduces the service life of the speaker; in order to ensure the position stability of the speaker during installation, it is necessary to use multiple bolts to fix the surface of the speaker on the support structure, but the bottom of the speaker is not well fixed, and when in use The vibration feeling is strong, which affects the sound quality, and the number of combined speakers is large, the assembly and disassembly process is cumbersome, and the practicability is not good
