SinoTD-6 Communication Transducer

A broadband high-power communication transducer with low mechanical quality factor (Low QM)

Product details

1

Product introduction

SinoTD-6 transducer is a broadband high-power communication transducer with low mechanical quality factor (Low QM), designed specifically for underwater analog and digital communication. This transducer has circular directionality and is particularly suitable for communication in underwater voice and message channels on a horizontal plane. Its center frequency is 6kHz, with a wide operating frequency range, supporting underwater communication from medium to short distances to long distances, ensuring stable signal transmission.

The SinoTD-6 transducer can achieve long-distance information transmission under low frequency conditions, and can transmit information within a range of up to 10 kilometers. Its design is not only suitable for underwater communication, but can also be combined into linear, planar, or curved arrays through multiple transducers to generate higher sound pressure levels or achieve specific directional responses. The transducer also combines durability and low self noise design, making it suitable for long-term deployment in environments such as oceans, rivers, or lakes, providing strong support for bioacoustic research, target detection, and sound field generation.

Overall, SinoTD-6 transducers have become an ideal choice for various underwater applications due to their broadband performance, low mechanical quality factor, and strong signal transmission capabilities.

Main application scenarios

(1) Underwater communication: SinoTD-6 is highly suitable for underwater communication over medium to long distances, especially in the 6kHz frequency band, which provides moderate penetration and signal propagation distance, making it suitable for signal transmission between underwater platforms, submersibles, and fixed installations.

(2) Target detection and positioning: In underwater detection and echolocation applications, SinoTD-6 can provide precise sound wave transmission and reception functions, suitable for tasks such as underwater target detection, object positioning, and underwater navigation.

(3) Bioacoustic research: The 6kHz frequency band of SinoTD-6 is suitable for detecting the sound and behavior of marine mammals and fish. It can be used to record and analyze low-frequency sound waves emitted by underwater organisms, supporting bioacoustic analysis.

(4) Environmental noise monitoring: This transducer is also suitable for underwater noise measurement and monitoring, helping researchers analyze the environmental noise levels and sources of oceans, rivers, or lakes.
