发明名称 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.

主权项 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.
