A mysterious exhibition to appreciate the clear sound of the full-digital speaker OVO

From August 11 - 18, a mysterious exhibition was held at the Sendai-Forus, department store in Sendai. It is an exhibition to appreciate the "sound".

This event was held by JDSound, who develops audio equipment such as full-digital speaker OVO. They were established after the Great East Japan Earthquake, with the intention of helping boost the economy of Tohoku by making electronic products in the area. OVO is their main product, and it play clear sound via USB instead of Bluetooth. Advantages include better sound quality, no delayed output, no setting up procedure and no need for battery charging. You simply plug it into whatever device you want to amp up the audio on. Its full-digital logic system can handle audio signals and output digital ones using less power than an analog system. It left and right sound channels for a stereo effect and boosts sudden or loud sounds by drawing extra energy to the speaker when needed.

At this exhibition, we were able to enjoy various ASMR(Autonomous Sensory Meridian Response) sounds played by OVO.

This is how the venue is. It was an exhibition to appreciate the sound, so of course there were no paintings or photos, just black canvases on an inorganic concrete wall.

The title of this work is "not in time and the madness". As I listened to the canvas to appreciate the sound, I heard a quick touch typing sound in it, so I understood the meaning of the title. What impressed me was that, despite the noisy venue, I was able to hear a clear and realistic sound by bringing my ears closer to the canvas. Why was there an event to enjoy sound at a department store with a lot of noise? This was their challenge.

When I looked at the back of the canvas, OVO was directly taped there! A very simple setting :)
However, it is a good technique to get people who are not familiar with sound and gadgets to understand the performance of OVO. Moreover, it is easy to remain in people's memories because it involves an active action of listening to the sound by bringing the ear close to the canvas.

Sounds that seemed to have a relaxing effect such as bonfire sounds, water sounds, people whispering, and sound of cutting vegetables were on display.
It attracted many people's attention and about 3000 people visited here. This is a staggering figure at a local event.

Currently, they are actively working to release OVO in collaboration with local professional baseball teams and virtual Youtuber, and to release a version of OVO that can customize the exterior. Initially, they raised development funds through crowd funding, but raised more than 90 million yen in only in Japan. Now, OVO is also sold on Amazon.
