Title: LOW-LOSS/HIGH-FIDELITY VIBRATION WAVE OUTPUT AND RECEIVING DEVICE IN HIGH/LOW PRESSURE ENVIRONMENT
Abstract:
A low-loss/high-fidelity vibration wave output and receiving device in high/low pressure environment, comprising but not limited to: a soft gas bag (1), a vibrating body (2) and an audio conversion unit. The rigidity of the soft gas bag (1) is less than that of the vibrating body (2), such that the soft gas bag (1) is deformed earlier than the vibrating body (2) under the effect of the environmental pressure; the soft gas bag (1) and the vibrating body (2) are in closed connection to form a closed air space; the audio conversion unit is provided inside the closed air space in such manner that the audio conversion unit can receive the vibration of the vibrating body (2), convert the vibration into other signals and output the signals to the space outside the closed air space, and/or can convert the other signals received from the space outside the closed air space into signals that can drive the vibrating body (2) to vibrate; under the effects of underwater pressures of different depths, the soft gas bag (1) is compressed by different degrees, such that the pressure inside the closed air space is always consistent with the outside water pressure.
