Oscillator in liquid |
摘要 |
A oscillator in a liquid includes an actuator element oscillating in a reciprocating manner, and a sound-producing element attached to the actuator element, whereby the actuator element generates a motion in the sound-producing element for producing a sound. The oscillator is made open, whereby the pressure of liquid acts both on a first surface and on a second surface of the wall of the sound-producing element while the sound source is in the liquid. The material and/or structure of the wall of the sound-producing element is provided to be such that the distance between the first surface and the second surface of the wall varies as sound is produced. |

1. An oscillator in a liquid comprising:
an actuator element oscillating in a reciprocating manner, whereby the distance between the ends of the actuator element varies, and a sound-producing element attached to the actuator element, whereby the actuator element generates a motion in the sound-producing element for producing a sound, the oscillator being provided open, whereby liquid pressure acts both on a first surface and on a second surface of the wall of the sound-producing element while the oscillator is in the liquid, wherein the sound-producing element is structurally configured to comprise a flexible layer in a manner such that the distance between the first surface and the second surface of the wall varies as sound is produced;wherein the sound-producing element is structurally configured in a manner such that the first surface and the second surface of the wall oscillate independently out of phase with each other as sound is produced. |
