AI Technical Summary

Technical Problem

The existing speakers are insufficient moisture-proof in humid environments, resulting in short-circuiting of internal electronic components and line connection ports, and insufficient safety.

Method used

A MEMS speaker with high moisture resistance is designed, using technical means such as moisture-proof cotton plates and dust-proof nets to prevent moisture from the inner cavity of the shell through moisture-proof cotton plates, and a dust-proof net is used to intercept external dust to ensure that the electronic components are not affected by moisture and dust.

Benefits of technology

It improves the service cycle and safety of the electronic components in the inner cavity of the speaker, ensures that the speaker can still work normally in humid environments, and the convenience of replacing the moisture-proof cotton board is improved.

Abstract

The utility model discloses an MEMS horn with high moisture resistance, which belongs to the technical field of horns and comprises a shell, two sound production covers are fixedly assembled at the top of the shell, a cover plate is fixedly mounted on one side, far away from the sound production covers, of the shell through screws, and a plurality of heat dissipation grooves are uniformly formed in the inner wall of the cover plate. A positioning strip is fixedly assembled on the inner wall of the shell, and the inner wall of the positioning strip is fixedly connected with one end of a spring; the moistureproof operation is performed on the inner cavity of the shell through the moistureproof cotton plate, when the moistureproof cotton plate needs to be replaced, the pressing plate can be pulled to move upwards, a new moistureproof cotton plate is placed between the pressing plate and the positioning strip, and then the moistureproof cotton plate is stably positioned between the positioning strip and the pressing plate by means of resetting of the acting force of the spring. The replacement convenience is improved, so that the problem of insufficient safety caused by easy short circuit of internal electronic elements and line connection ports in a humid environment due to insufficient moisture resistance is avoided.
