Sound Fun has launched the lower-priced Mirai Speaker Mini. The patented curved diaphragm speaker design allows TV viewers who are hard of hearing to hear the dialogue clearly without turning up the sound.

Sound Fun has launched the lower-priced Mirai Speaker Mini in Japan. The speaker allows television viewers to hear dialogue better without needing to turn up the sound excessively.

Hearing becomes more difficult as people age, so they often turn up the TV volume. However, this annoys normal users with sound that is too loud. Alternatives include wearing earphones or hearing aids, but some dislike these cumbersome options.

The Mirai Speaker Mini uses a patented, curved diaphragm speaker to drive the air, so the sound produced by the Mirai remains audible at greater distances. Using this speaker, TV viewers with poor hearing do not need to increase the volume excessively.

The original 2015 Mirai Speaker was designed to enhance sound clarity in noisy areas such as banks and airports, and the first home model was launched in 2020. The latest Mirai Speaker Mini provides the same performance with an optimized design for a lower price and a simplified 2-step setup with most television sets.

The 15 watt speaker has a frequency range of 180 Hz to 20 kHz. The mono speaker measures 3.5 x 6.1 x 7.9 inches (90 x 154 x 200 mm) and weighs 1.3 pounds (0.6 kg). A 3.5 mm input jack accepts audio from TVs and other sources.

The Mirai Speaker Mini is priced at 19,800 yen (approx. $132) from Sound Fun’s Japan site. The US website does not list the Mini for sale, but Americans can still enjoy clearer TV dialogue with the Mirai Speaker Stereo (here at Amazon).

Mirai Speaker Mini Features

More affordable while maintaining the same clear sound

While evolving the curved diaphragm that produces audible sound, we have achieved pricing in the 10,000-yen range by simplifying the structure.

Simple design that does not over-emphasize the curved surface sound while respecting its originality

While maintaining the fan-shaped form typical of curved surface sound, the simple and stylish design looks like a black rectangle from the front that does not interfere with TV viewing.

Attention to user-friendliness based on customer feedback

The Mirai speaker can be easily connected in two steps, "anyone can install it without hesitation. In addition, we have made efforts to improve the usability of the product, such as a "packing box" with a device to prevent loss of accessories, an "instruction

" with illustrations for intuitive understanding, and a "longer cord" to accommodate larger televisions.

Hearing/Sound-related Problems in Daily Life, No. 1: "TV Sound

According to the results of our survey, the most common problem related to hearing/sound in daily life is "TV sound". Those in their 30s and 40s cited difficulty in hearing the TV sound mixed in with the sounds of daily life, those in their 50s cited problems caused by their parents watching TV too loudly, and those in their 60s and older cited difficulty in hearing TV dialogue. These results clearly indicate that there is a need for TV listening comprehension regardless of generation. Therefore, by keeping the price of "Mirai Speaker Mini" low, we hope to help make the daily lives of more people more comfortable.

Mirai Speaker official EC site

What is "Mirai Speaker®"'s unique "Curved Surface Sound", a new technology that transforms "sound" itself?

The diaphragm of a conventional speaker is a cone-shaped diaphragm, whereas the diaphragm of the "Mirai Speaker®" is a curved flat plate. The curved sound emitted from the curved diaphragm delivers clear sound over a wide distance, helping people who have trouble hearing.

Difference of "sound waves" from conventional speakers

Sound waves are difficult to visualize, but with the cooperation of Associate Professor Okubo of Tokyo Metropolitan University, we conducted a simulation analysis of the movement of the diaphragm to understand why sound waves unique to Mirai speakers are generated. It was confirmed that, unlike conventional speakers, the Mirai speaker creates a sound field that firmly delivers sound over a wide area in the high frequency range. We will continue our research on the "curved surface sound" that will change the history of speakers for the next 100 years.
