Description

Technical Field

[0001] This utility model relates to the field of rural tourism technology, specifically to a loudspeaker. Background Technology

[0002] The loudspeakers used in rural tourism are portable amplification devices primarily used for guided tours, event announcements, and background music playback in rural scenic areas. These loudspeakers typically have strong amplification capabilities, covering a large area, facilitating real-time communication for staff and enhancing the visitor experience through cultural explanations.

[0003] A loudspeaker for rural tourism disclosed in Chinese Patent Publication No. CN214799803U is equipped with a rear cover and a cylindrical cover. When the loudspeaker is not in use, it can be sealed to protect it from rain and dust, thus extending its service life. However, the loudspeaker has low overall functionality. When used outdoors in rural areas for a long time, the loudspeaker's power will be consumed quickly, making it unable to continue to function effectively and affecting the stability of the loudspeaker's use.

[0006] Preferably, a handle is fixedly connected to one side of the bottom end of the speaker body, and a speaker is installed in the middle of one side of the speaker body.

[0007] Preferably, a generator is installed on one side of the top of the lithium battery, and a connecting groove for insertion with the generator is provided at the bottom of the fan.

[0008] Preferably, the limiting mechanism includes a slot on one side of the photovoltaic panel, an annular groove on the outside of the fan, a handle rotatably connected to the middle position of the top of the horn body, a rotating shaft fixedly connected to the bottom of the handle, and two fixedly connected to the two sides of the rotating shaft.

[0009] Preferably, a first movable block is fixedly connected to one side, a spring is fixedly connected to one side of the first movable block, and a positioning rod is fixedly connected to the side of the first movable block away from the spring.

[0010] Preferably, the connecting mechanism includes a rotating ring that is slidably connected to the outside of the connector, limit sliders that are evenly and uniformly fixed to both sides of the rotating ring, a pull rope that is evenly and uniformly fixed to the inside of the rotating ring, a second movable block that is slidably and uniformly connected to the pull rope on one side of the inside of the connector, a magnetic rod that is fixedly connected to one side of the second movable block, and positioning grooves that are magnetically attracted to the magnetic rod that are evenly and uniformly arranged on the outside of the loudspeaker cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This type of loudspeaker has photovoltaic panels and a heat exchanger fan installed on both sides of the top of the loudspeaker body. The photovoltaic panels can convert light energy into electrical energy and store it in a lithium battery. At the same time, the external natural wind blows the heat exchanger fan, which can rotate on top of the generator, thereby converting mechanical energy into electrical energy and storing it in the lithium battery. The lithium battery then effectively powers the loudspeaker body, improving the overall battery life of the loudspeaker in rural tourism. The limiting mechanism allows for quick and easy disassembly and replacement of the photovoltaic panels and heat exchanger fan, improving the overall flexibility of the loudspeaker's use.

[0013] 2. This type of loudspeaker features a speaker cover installed on one side of the connector. When the speaker cover is inserted into the connector, the magnetic force of the magnetic rod allows it to be inserted into the positioning slot on the speaker cover, enabling quick installation of the speaker cover on one side of the speaker body. When the rotating ring on the connector is rotated, the rotating ring can be pulled by a rope to move the second movable block, which in turn causes the magnetic rod to be pulled out of the positioning slot on the speaker cover. This allows for quick replacement and cleaning of the speaker cover. The modular design improves the portability of the loudspeaker and facilitates the replacement of various components, thus extending the overall service life of the loudspeaker.
