Traditional deep sea acoustic release transponder has many problems, such as large volume, heavy weight, high cost and difficult dynamic sealing of the driving mechanism. The new acoustic release device program is expected to solve these problems. By contrast, this article determines to use the no-sealing electromagnet to provide the driving force during the release process. A control circuit and mechanical structure were designed. Using the electromagnetic solenoid's inductance change during the release process, throughout a series of transformation of the control circuit, it can recycle the feedback information and realizes the multiplex function of the electromagnet control wires. Though the intermodulation test, the feasibility of the whole scheme is verified. Compared with the existing acoustic releaser, the device has more advantages such as smaller volume and weight, lower cost and other advantages. Meanwhile, the structure is more ingenious and easy to control and deserves further research, and will also provide a useful reference for overall packaging and design of acoustic release transponder.
