Example Embodiment

[0018] Example 1, see image 3 , A pressure-sensitive trigger type sound generator suitable for underwater use, comprising a sound generator 61, a controller 62, a No. 1 pressure sensor 63, a No. 2 pressure sensor 64 and a flexible liquid storage bag 65. The flexible liquid storage bag 65 is filled with liquid. The No. 1 pressure sensor 63 is arranged in the flexible liquid storage bag 66. The second pressure sensor 64 is arranged outside the flexible liquid storage bag 65. Both the sound generator 61 and the controller 62 are arranged in the flexible liquid storage bag 65. The first pressure sensor 63, the second pressure sensor 64, and the sounder 61 are electrically connected to the controller 62.

[0019] The sounder 61 includes a driving unit 611, a whistle 612, and a No. 1 fixed compression plate 613, a No. 1 airbag 614, a dynamic compression plate 615, a No. 2 airbag 616, and a No. 2 fixed compression plate 617 which are arranged in sequence. The driving unit 611 inclu...

Example Embodiment

[0022] The second embodiment is different from the first embodiment: if AB is greater than 0 for more than 30 seconds, it means that the force source that causes the pressure of the flexible storage bag 65 to increase cannot be driven away by sound, that is, it is not an animal such as a fish. As a result, the sounding drive will have no effect. At this time, the controller 62 stops the sounder 61 and modifies the preset value B to the pressure detected by the No. 1 pressure sensor at the time when the sounder stops sounding minus the pressure detected by the No. 2 sensor The difference A from the pressure. The above modification will cause the phenomenon that if the pressure increase in the flexible storage bag 65 is caused by a sudden impact, the preset value B will be greater than the instant value of the difference A after the external force disappears. The existence of this phenomenon will lead to The phenomenon that the fish cannot be detected when the protective shell 7 ...

Abstract

The invention relates to an underwater sounding device. A pressure induction triggered sounding device suitable for underwater includes a sounding device, a controller, a first pressure sensor, a second pressure sensor, and a flexible liquid storage bag. The flexible liquid storage bag is filled with liquid. The first pressure sensor is arranged in the flexible liquid storage bag. The second pressure sensor is used for detecting the water pressure outside the flexible liquid storage bag. When the difference obtained by subtracting the pressure detected by the second pressure sensor from the pressure detected by the first pressure sensor is greater than a preset value, the controller makes the sounding device make sound. The invention provides a pressure induction triggered sounding devicesuitable for underwater. The problem that the existing sounding device can be controlled only through direct action on the switch is solved.

Description

Technical field [0001] The invention relates to an underwater generator, in particular to a pressure-sensitive trigger type sound generator suitable for underwater. Background technique [0002] In production and life, sometimes it is necessary to set up a sounding device underwater to sound. However, the existing sound generating device such as a speaker realizes the control of the sound generator by directly acting on the switch, which has the disadvantage of inconvenient control when directly acting on the switch for control. Summary of the invention [0003] The invention provides a pressure-sensitive trigger type sound generator suitable for underwater, which solves the problem that the existing generator needs to directly act on the switch for control. [0004] The above technical problems are solved by the following technical solutions: a pressure-sensitive trigger type sound generator suitable for underwater, which is characterized by comprising a sound generator, a control...
