The secret to a soft, deep sound

When listening to music on a smartphone, the sound coming from the speaker is scattered in all directions, making the volume low.

"KUMIKO" amplifies the volume of sound by focusing the sound in one direction and reverberating it inside the speaker, just like a megaphone can project a voice far and wide.

The secret lies in the internal structure of the speaker, which is similar to that of a back-loaded horn speaker. The internal space gradually expands, making it easier to amplify the sound.

Commitment to wood

"KUMIKO" is, The product is made from ash wood, and developer TATARA ACOUSTIC has utilized their knowledge and experience gained from building audio speaker boxes for Japanese manufacturers over many years .

The company's first product, "KUMIKO," was made from soft red pine, but they eventually decided on ash, which is harder than red pine, as the best material for producing good sound not only in front of the speaker but also to the sides and a wide range, even with a limited volume of the sound source.

Ash material has the following features:

  • The bass has a tight sound and doesn't become muddy.
  • The volume coming out of the speaker increases.
  • The clarity of each note of sounds such as piano is improved.
  • It becomes a gorgeous sound.
  • This makes the speaker suitable for a wide range of music genres.

When sound passes through "KUMIKO", the sound reverberates and amplifies in volume, reducing the high-pitched rustling sound that is typical of smartphones, and the characteristics of the ash material create this warm, deep sound.

"KUMIKO" development story

During the New Year holidays in 2019, the developer, TATARA ACOUSTIC's president, Mr. Sone, was spending time on a beach in Thailand. He was relaxing while listening to Japanese traditional music on his smartphone's speaker, and the image of a speaker box for smartphones came to mind. It suddenly crossed my mind.

"The sound coming from a smartphone is weak and harsh. Also, the crackling sound that is unique to smartphones is extremely irritating to the ears..."

From there, President Sone began to conduct repeated experiments, placing the smartphone in a vase or a wooden box. Remembering the speaker boxes he had made in the past, he repeatedly made prototypes and improved them in order to find the best possible sound quality for a smartphone.

"I've been making speaker boxes for a long time, so I have some idea of ​​what makes good sound. If I'm going to listen to sound, I want it to sound as good as possible. The sound that comes from wood is gentler and more soothing than the sound that comes from aluminum or plastic. Also, I want to cherish the warmth of the appearance of wood."

Finally, President Sone was satisfied with the sound reproduction, and the acoustic sound box, "KUMIKO," was completed with a hemp leaf pattern created using the traditional Japanese woodworking technique of "Kumiko."
