Wireless energy and information transmission device based on sound waves

Abstract

The invention relates to a wireless energy and information transmission device based on sound waves. The invention includes a transmitting end and a receiving end; the transmitting end and the receiving end are equipped with transducers respectively, and the transducers are arranged in their respective half-cavities; when working, the two half-cavities are docked to form a closed cavity, and the transmitting end The transducer converts electrical energy and electrical signals into sound waves, and the sound waves propagate to the receiving end transducer directly or after one or more reflections in the cavity; the receiving end transducer converts the received sound waves into electrical energy and electrical signals. Signal; through this process, energy and signal are transmitted from the transmitting end to the receiving end through sound wave transmission. The invention realizes the sound concentration effect through the cavity formed by the docking of the transmitting end and the receiving end, and this effect can increase the intensity of the sound wave received by the transducer at the receiving end, thereby improving the transmission efficiency.

[0003] In the underwater environment, power and signal transmission interface devices are often needed. Now the commonly used interface device is the underwater wet plug interface. The wet plug interface technology is relatively mature, but there are inherent shortcomings: the water around the working environment is conductive, Any very small amount of water leakage may cause a short circuit or even cause an accident; wet plug connectors must pass tens of kilograms of plugging force to achieve normal plugging and unplugging operations, which is a big challenge for automatic working electromechanical equipment; The wet-plug interface requires frequent extrusion and plug-in operations, and the wear caused by the huge plug-in force seriously reduces the service life, and frequent maintenance is required to ensure safety; wet-plug interfaces are generally expensive, and for some simple devices, The cost of wet plugging interface even exceeds the cost of the device itself
