For the stable operation of the phone, a waterproof structure needs to be installed on the outside. A waterproof structure is a design or construction that aims to prevent liquids from penetrating or entering a design feature of a building, equipment or product. It can be used in various occasions, such as buildings, vehicles, electronic equipment, furniture, etc., to protect them from water.

The utility model quickly locates the speaker through the positioning through hole and the guide cylinder. At this time, the sleeve is squeezed to move into the guide cylinder, and the sleeve drives the pressure plate to squeeze the spring. When the card slot is aligned with the sleeve, the sleeve is inserted into the card slot under the action of the spring elastic force to complete the fixing of the speaker, and the disassembly and assembly are more convenient and quick, and the operation is simple, which can reduce the difficulty of later maintenance.

[0004] The working principle of the above patent specification states that "under the action of the elastic force of the spring 33, the sleeve 32 is inserted into the slot 232 to fix the speaker 2. The installation is convenient and quick. When disassembly is required, the push block 361 is pushed to make the sliding rod 36 slide in the strip limiting hole 311. The sliding rod 36 is used to drive the sleeve 32 out of the slot 232 to complete the disassembly of the speaker 2. The operation is simple and can reduce the difficulty of later maintenance." This allows for the rapid disassembly and installation of the speaker 2. However, frequent installation and disassembly increases the probability of damage to the speaker and increases the probability of the speaker falling due to accidental human touch. Therefore, in response to the above-mentioned deficiencies, a new waterproof structure for a smart phone speaker is proposed. Utility Model Content
