Fountain underwater acoustic device

Abstract

The invention discloses a fountain underwater acoustic device, includes an audio body and a washer, A loudspeaker is arrange inside that acoustic main body, and the outer surface of the loudspeaker isfixedly provided with a water-proof sandwich layer, the loudspeaker is provided with an LED light band above the loudspeaker, the outer surface of the acoustic main body is provided with a power supply interface, and the bottom end of the acoustic body is provided with a fixing frame, the loudspeaker is provided with a waterproof sound film inside, and the waterproof sound film is fixedly connected with the lead coil through a gasket, A magnetic pole is arrange at that bottom end of the lead coil, and the bottom end of the magnetic pole is provided with a basin frame, A magnetic core is arrange at that bottom end of the basin frame, and a magnetic cylinder is fixedly installed at the bottom end of the magnetic core, The invention discloses a fountain underwater acoustic device, a loudspeaker and a power supply interface, which can effectively block the infiltration of the fountain water to the internal structure, so that the acoustic body can work normally on the underwater, and can realize charging on the underwater, which is convenient and practical, suitable for different working conditions, and has a better use prospect.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a fountain underwater sound device. Background technique [0002] Refers to sounds other than human language and music, including sounds from the natural environment, animals, machines and tools, and various sounds from human actions. Audio probably includes power amplifiers, peripheral equipment (including compressors, effects, equalizers, VCD, DVD, etc.), speakers (speakers, speakers), mixers, microphones, display devices, etc. add up to a set. Speakers are sound output devices, speakers, and subwoofers. A speaker includes high, low, and medium speakers, three but not necessarily three. The existing fountain underwater audio devices have certain disadvantages in use. The waterproof performance is not good enough, and short circuits are prone to occur during use. Underwater charging cannot be realized, and there is no good viewing effect due to lack of good light when used ...

AI Technical Summary

Problems solved by technology

A speaker includes high, low, and medium speakers, three but not necessarily three. The existing fountain underwater audio devices have certain disadvantages in use. The waterproof performance is not good enough, and short circuits are prone to occur during use. Underwater charging cannot be realized, and there is no good viewing effect due to lack of good light when used at night. Therefore, we propose a fountain underwater audio device
