ลำโพงสำหรับติดตั้งใต้น้ำ ยี่ห้อ EV Electro-Voice รุ่น UW30 a departure from conventional underwater sound source design. Utilizing the the water proof barrier as the sound source radiator provides more full range sound in one of the toughest acoustic environments. The UW30 represents a departure in the design of underwater sound sources. Its unique design U.S. Patent #3670299 utilizes the case’s structural enclosure as the sound transducer.
This development makes possible a speaker that has no metal parts exposed to the outside thus eliminating rust corrosion or other causes of short‐life expectancy.
The transducer principle and its strong construction allow the UW30 to operate at much greater depths than any prior type of underwater loudspeaker design. The 12.7‐ounce ceramic magnet and state‐of‐the‐art voice‐coil construction ensure full‐fidelity response with the lowest possible distortion throughout its power range.
The UW30 underwater loudspeaker is designed for permanent installation and completely submerged operation. All internal components are encapsulated with a “hot‑melt” (Polyamide Copolymer) process. The outer case is constructed of high impact ABS (Acrylonitrile butadiene styrene) plastic. Ideal for installation in both fresh and saltwater pools the UW30 can even be installed in ocean environments without adverse effect.
Underwater speakers are required equipment for many activities in commercial and luxury resort pools. As specified by the American Athletic Union underwater speakers are required for synchronized swimming events and instructions in Olympic pools. They are used for water ballets and similar water shows. When underwater speakers are installed in resort and private pools the effect of music played underwater is truly an enchanting experience.
