The invention relates to an ultrasonic transducer for underwater distance measurement, which comprises a shell, an inner cavity is arranged in the shell, a circuit board and a plurality of transduction sheets are arranged in the inner cavity, and the circuit board is connected with the transduction sheets; the transduction pieces are fixedly connected with the inner cavity, the multiple transduction pieces are arranged in an inclined mode, and included angles are formed between the inclined transduction pieces. The ultrasonic transducer for underwater distance measurement is provided with a plurality of transduction sheets, and the transduction sheets are obliquely arranged, so that the detection angle of the ultrasonic transducer for underwater distance measurement is increased, the ultrasonic transducer for underwater distance measurement can meet short-distance and long-distance detection, and the detection precision is high. According to the system of the ultrasonic transducer for underwater distance measurement, the detection angle is increased under the conditions that the working frequency is not reduced and the size of the probe is not greatly increased through circuit design and cooperation among the circuit modules.

    本申请是关于一种水下测距的超声波换能器,包括:壳体,所述壳体内设有内腔,所述内腔内设有电路板、多个换能片,所述电路板与所述换能片连接;所述换能片与所述内腔固定连接,多个所述换能片倾斜设置,倾斜的所述换能片之间形成夹角。该水下测距的超声波换能器上设有多个换能片,所述换能片倾斜设置,增大该水下测距的超声波换能器的探测角度,使得该水下测距的超声波换能器满足近距离以及远距离的探测,探测精度高。该种水下测距的超声波换能器的系统,通过电路设计及各电路模块之间的配合在不降低工作频率及不大幅增大探头尺寸的情况下实现探测角度的增大。
