    • The invention relates to an oscillator in a liquid. The oscillator in the liquid includes an actuator element (1) oscillating in a reciprocating manner, and a sound-producing element (2) attached to the actuator element (1), whereby the actuator element (1) generates a motion in the sound-producing element (2) for producing a sound. The oscillator is made open, whereby the pressure of liquid acts both on a first surface (4) and on a second surface (5) of the wall of the sound-producing element while the sound source is in the liquid. The material and/or structure of the wall (3) of the sound-producing element is provided to be such that the distance between the first surface (4) and the second surface (5) of the wall varies as sound is produced.

    • Mouthpiece (1), and speaker assemblies (8) for underwater speech using SCUBA and snorkel equipment. Mouthpiece (1) is characterized by a molded rubber or plastic mouthpiece having a connector (5) for use with a regulator (12) or a snorkel (30), a lip cup (3), a pair of elongated, serpentine or curved teeth grips or bites (4) extending from the lip cup (3) for gripping by the jaw teeth of a SCUBA diver or snorkeler and facilitating movement of the lips to enable underwater speech. The mouthpiece (1) is designed for attachment directly to an underwater speaker (16), a snorkel (30), a snorkel and speaker combination (10), or to the mouthpiece of a conventional second stage regulator (12), and speaker combination. The underwater speaker (16) includes a pair of flexible membranes (22) connected at a common perimeter (23) designed to pulse, to flex responsive to the pressure pulses of a diver or snorkeler's breath, and voice.

    • A boxed loudspeaker having an isolation enclosure arranged to provide a variable volume of trapped air in the isolation enclosure. The variable volume of the isolation enclosure is provided by dividing the isolation enclosure into a wet volume and a dry volume where the wet and dry volumes are connected by a chimney. An opening is provided through the isolation enclosure to the wet volume. And the entrance to the chimney from the wet volume is configured to be arranged above the opening when installed. Advantageously, a fluid path is provided from the dry volume that surrounds the isolated side of the diaphragm to the external environment via the chimney and wet volume. When the loudspeaker is not submerged in water, the fluid path provides pressure equalisation between the sides of the diaphragm to reduce static force Fn,s. The wet volume acts to trap air in the isolation enclosure when the boxed loudspeaker is submerged into water above the opening. If a temperature drop occurs in the volume of trapped air in the isolation enclosure when submerged, the pressure in the trapped air also drops, which acts to suck in water into the wet volume. By sucking in water, the volume of the trapped air is reduced, therefore the pressure differential between the two sides of the diaphragm can also be minimised. With a minimal pressure differential the static force Fn,s is also minimised even when the boxed loudspeaker is submerged.
