Firstly, the structure size of the transducer\u2019s sensitive component was designed by using ANSYS simulation software. Secondly, the piezoelectric composite ring-shaped sensitive component was fabricated by the piezoelectric composite curved-surface forming process, and the matching layer was coated on the periphery of the ring-shaped piezoelectric composite material. Finally, it was encapsulated and the electrodes were drawn out to make a high-frequency broadband horizontal omnidirectional water acoustic transducer prototype. After testing, the working frequency range of the transducer was 230\u2013380 kHz, and the maximum transmission voltage response was 168 dB in the water.<\/jats:p>","DOI":"10.3390\/s18072347","type":"journal-article","created":{"date-parts":[[2018,7,20]],"date-time":"2018-07-20T02:10:11Z","timestamp":1532052611000},"page":"2347","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Research and Fabrication of High-Frequency Broadband and Omnidirectional Transmitting Transducer"],"prefix":"10.3390","volume":"18","author":[{"given":"Shaohua","family":"Hao","sequence":"first","affiliation":[{"name":"School of Science, Beijing Information Science and Technology University, Beijing 100192, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongwei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Science, Beijing Information Science and Technology University, Beijing 100192, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Zhong","sequence":"additional","affiliation":[{"name":"Sensing Technology Research Center, Beijing Information Science and Technology University, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Likun","family":"Wang","sequence":"additional","affiliation":[{"name":"Sensing Technology Research Center, Beijing Information Science and Technology University, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Science, Beijing Information Science and Technology University, Beijing 100192, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,19]]},"reference":[{"key":"ref_1","unstructured":"Cochran, S., Parker, M., and Marin-Franch, P.
