Description

Technical Field

[0001] The utility model of the present application relates to the technical field of Bluetooth speakers, and particularly relates to a waterproof portable Bluetooth speaker. Background Technique

[0002] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. The speaker is an extremely important part of the audio system; because it is responsible for the key task of converting electrical signals into sound signals for people's ears to directly listen to. It has to directly deal with people's sense of hearing, and people's sense of hearing is very sensitive and has a strong ability to distinguish the timbre of complex sounds. Since the subjective feeling of sound by the human ear is the most important criterion for evaluating the sound quality of an audio system, therefore, the sound and performance level of the speaker play a key role in the sound quality of an audio system.

[0003] In the actual use process, a very important reason affecting the sound and performance of the speaker is the waterproof function, so speakers all have waterproof requirements. Due to reasons such as the installation of the speaker, in the current assembly of speakers, generally, the upper shell and the bottom shell are fixed by buckles and screws. The waterproofing between the upper shell and the bottom shell is only carried out by waterproof glue or a waterproof rubber ring between the upper shell and the bottom shell of the speaker. For the waterproofing of screwing, generally, a soft gasket needs to be set before screwing. Since the soft gasket part is small, it is very easy to be displaced and the waterproof effect is not good. And when the speaker is disassembled for rework, when unscrewing the screws, the soft gasket will also be lifted together with the screws, but the soft gasket cannot be used for a second time, resulting in material waste and low overall assembly efficiency of the Bluetooth speaker. Summary of the Utility Model

The circuit board 11 and the battery 12 are located in the cavity. A speaker 40 is fixed on the middle frame 20. The face mask 30 is covered on the middle frame 20. A plurality of screw posts 101 are integrally formed and protruded on the bottom case 10. The screw posts 101 are hollow. A plurality of screw soft glue holes 201 corresponding to the screw posts 101 are integrally formed on the middle frame 20. When the middle frame 20 is covered on the bottom case 10, the screw posts 101 on the bottom case 10 pass through the screw soft glue holes 201, and the bottom case 10 and the middle frame 20 are fixed by a screw 50 passing through the hollow part of the screw post 101. A sealing groove 102 is arranged along the edge of the bottom case 10, and a sealing ring 103 is arranged in the sealing groove 102. All the screw posts 101 are arranged inside the sealing groove 102. In this way, when the bottom case 10 and the middle frame 20 are covered and fixed, the screw posts 101 arranged inside the sealing groove 102 can well seal and waterproof the cavity formed by the middle frame 20 and the bottom case 10 lid.

[0028] One end of the middle frame 20 is provided with a handle 21. The handle 21 includes a fixing part 211 and a movable buckle 212. One end of the fixing part 211 is fixed to the frame body of the middle frame 20. The movable buckle 212 includes an abutting end 2121 and a holding end 2122. The other end of the fixing part 211 abuts against the abutting end 2121 of the movable buckle 212. The holding end 2122 of the movable buckle 212 is rotatably fixed on the middle frame 20.

[0029] A circular fixing through hole (not shown in the figure) is arranged on the holding end 2122 of the movable buckle 212. A circular fixing groove (not shown in the figure) and an abutting groove (not labeled in the figure) are arranged on the middle frame 20.
