Description

Outdoor audio device for physical and mental healing by playbacking emotion stimulative sound source}

The present invention relates to an outdoor audio device that is installed in a public area where the public is concentrated to reproduce sound sources, and more specifically, to regenerate sound sources such as poetry recitations, sayings, classical music, and nursery rhymes to replenish emotional purification as well as positive energy. It relates to an outdoor audio device that can contribute to enhancing the quality of life through the enjoyment of elegant culture and genuine relaxation and healing.

Typically, outdoor audio devices installed in public areas where the public is densely reproduced sound sources that achieve purposes such as public relations, guidance, education, and safety. Existing audio devices do not have a sensor that detects the human body, so they always play sound sources, or the public directly presses a button to play them.

In this case, since the sound source is reproduced even when no one is present, it causes noise pollution to the surrounding public, and there is a problem that the correct meaning cannot be delivered due to listening during playback.

And, since the button playback method does not promote interest to the public, as a result, the sound source cannot be played unless the button is pressed, and there is an inconvenient problem of having to manually play one by one with the embarrassment that someone among the public must appear even if they want to listen. .

Therefore, as a solution to this problem, Korean Patent Application Publication No. 10-2003-0020031, Korean Patent Application Publication No. 10-2009-0011630, Korean Patent Application Publication No. 10-2009-0092611, and Korean Patent Publication No. I have proposed No. 10-0993299.

According to the proposed literature, there is a difference in the application field and detailed method, but in common, it is improved so that the set sound source can be reproduced by automatically detecting the public approaching the area.

On the other hand, poetry can fully express a person's thoughts and emotions, and is an excellent tool to connect the mind, and through poetry, it is possible to create creative arts such as movies, dances, paintings, and music, and to shed light on the world. In addition to contributing to the preservation of linguistic diversity, it can contribute to the development and exchange of human culture around the world by helping people perceive and understand things and the world, cultivating character, and asking new questions.

In other words, we are living in the era of high-tech science and technology, in which today's reckless verbal abuse, inundation of various media and information media, political slogans that cannot understand meaning, are driven by the noise of product advertisements, are deceived and manipulated, and everything is controlled by computers and smartphones. Poetry is a milestone for everyday life, confirmation of self-existence, and a mirror of self-purification through language.

Therefore, sound sources such as poetry reciting, sayings, classical music, and nursery rhymes are reproduced in the public area to enhance the emotional pursuit of busy modern people, as well as recharge positive energy, enhance the quality of life through the enjoyment of a dignified culture and genuine rest and healing. We need a way to contribute.

Due to the descending of the flow table 82d, a plurality of folded ribs 82b are spread to collect rainwater by the waterproof tent 82c, and the collected rainwater is supplied to the washing tank 71. Here, when the storage of the washing tank 71 is completed or the rain stops, the saliva 82b is immediately folded to stop collection.

And the fog collecting unit 85 is a clamp (85a) to induce attachment to the upper end of the post (11), a connection plate (85b) that is horizontally fastened to one end of the clamp (85a), and one side of the connection plate (85b) It is composed of a plurality of collection panels 85c having a mesh for collecting fog, and a collection container 85d disposed at the lower end of the collection panel 85c to collect falling water droplets and transfer them to the washing tank 71.

That is, moisture saturated in the air such as dew or fog is condensed in the form of water droplets by colliding and entangled with the net provided on the collecting panel 85c, and the condensed water droplets fall on the collecting container 85d by their own weight. Water droplets falling on the collecting tank 85d are collected and supplied to the washing tank 71.

At this time, the fixed type rainwater collecting unit 81 and the mist collecting unit 85 do not have a separate stopping means even when the storage of the washing tank 71 is completed, so they are connected to the outside at the top of the washing tank 71 to adjust the water level. It is desirable to form a discharge passage.

The present invention is not limited to the disclosed embodiments, and it is obvious to those of ordinary skill in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such variations or modifications will have to belong to the claims of the present invention.
