A smart bluetooth speaker

Abstract

The invention belongs to the technical field of sound boxes, and particularly relates to an intelligent Bluetooth sound box which comprises a fixed box body, a power generation module, a sand prevention module, a sound box module and an elastic telescopic air bag. A power generation module is mounted at the top of the fixed box body; Elastic telescopic air bags are installed on the top of the fixed box body and located on the two sides of the power generation module. Sand prevention modules are installed at the positions, corresponding to the two elastic telescopic air bags, in the fixed box body, a sound module is installed at the position, between the two sand prevention modules, in the fixed box body, and a dustproof module is arranged at the position, corresponding to the elastic telescopic air bags, of the top of the fixed box body. The power generation module comprises a generator, a storage battery, a rotating shaft and an impeller; The generator is arranged in the fixed box body, and a connecting base is installed at the bottom of the generator. Sand prevention and heat dissipation are carried out on the sound equipment module through the elastic sand-proof film, hot air inthe fixed box body is pumped out through the elastic telescopic air bag, the heat dissipation efficiency is improved, and the service life of the sound equipment module is prolonged.

Description

technical field [0001] The invention belongs to the technical field of sound boxes, in particular to an intelligent bluetooth sound box. Background technique [0002] The sound-generating part of the speaker is the speaker. The reason why the speaker exists in the box is mainly to prevent the sound wave signals from the front and back of the speaker diaphragm from directly forming a loop, so that only the high and medium frequency sounds with a small wavelength can be transmitted, while other The sound signal is superimposed and canceled out. In outdoor large-scale beach sports, outdoor speakers are often used for sound transmission. When using speakers on the beach, sand particles can easily enter the inside of the speakers and damage the speakers. The heat dissipation effect of the speaker is not good, which reduces the service life of the speaker. [0003] There are also some technical solutions for speakers in the prior art. For example, a Chinese patent with applicatio...

Problems solved by technology

However, this type of speaker cannot effectively prevent external dust from entering the inside of the speaker during heat dissipation, causing dust to accumulate inside the speaker, causing a short circuit and reducing the service life of the speaker. At the same time, the speaker is protected against dust and sand, which effectively improves the heat dissipation efficiency of the speaker and prolongs the service life
