This exceptional breakthrough in energy saving technology (previously only sold in Japan)

The highest quality of underwater speaker is here in Phuket. Tone is beautiful, apart from normal sound. The combination of the types of underwater speakers varies according to the use. It might be for swimming competition or for school pool. In other cases, it is used for means of communications in scuba diving or exchange of communications in large-scale water tank at aquarium. We hereby introduce some examples of combination that will be used for the synchronized swimming.
What is an underwater speaker?

UTX-30 - Luxury Hospitality Management The underwater speaker is a special speaker that conveys human voice or sound under water in the sea and the pool. This complete waterproof speaker is widely used for synchronized swimming, scuba diving, salvage, rescue, (lifesaving and maritime security) and in the nature such as culture fishery. To begin with, the difference between general speaker and underwater speaker is a method of conveying sound. In the air, we feel the air vibration through the eardrum and perceive it as sound. But in water, the eardrum does not function well. Instead, we perceive the sound through our “bone conduction” in which skull directly feels the vibration. This “bone conduction” is a mechanism of giving vibration to the bone (skull) to convey it directly to auditory nerve. Our underwater speaker has achieved to convey music and human voice by making the most of this bone conduction.

UETAX enjoys a lion's share of underwater speaker market

UETAX Corporation occupies the highest market share in production and sales of underwater acoustic equipment in Japan. UETAX underwater speakers have been playing an active role in the World Swimming Championship held in Fukuoka in 2001 and FINA Synchronised Swimming World Cup in 2005. They are also used in Tokyo Tatsumi International Swimming Center and Yokohama International Swimming Pool, which is the typical stage for synchronized swimming. They are also used in producing movies that involve the scene of sea such as “Umizaru” and “Water Boys” as well as the TV dramas. Thus, UETAX underwater speaker is now becoming essential at the site of producing such movies and dramas. Furthermore, the Self-Defense Force and the Police in administrative divisions also adopt the equipment.

UETAX underwater speakers are also adopted at daily drive-in fishery and culture fishery throughout Japan.
