An example buckle assembly includes a body and a latch. The body includes an integral whistle portion. The latch is configured to snapably mate with the body.

A sound suppressor for use in firearms, internal combustion engines, and numerous other sound-generating devices includes a structure having a plurality of ports, openings, or orifices which function as whistles and which suppress sound from a source of the sound using destructive interference. A combination of varying distances between components is configured for delaying the wave from one port or whistle to the next, so that the whistles are partially out of phase with respect to time, and placing the orifices of the whistles a certain distance apart to compensate for the remaining phase difference in order to create the desired destructive interference.

The invention is a plush and fabric animal shaped toy with sections of rope that extend out from the body of the toy and are connected via surgical tubing inside the plush toy that pull apart two layers of hook and loop material causing a ripping sound similar to that of Velcro. When the rope is released the hook and loop halves are reconnected and ready for the animal to pull again. The plush animal has embroidered face detail and squeakers and cellophane material located in the head or limbs of the toy adding additional noises to emit from the toy when a pet is playing with it.

A vehicle has a high-voltage store, which is provided for storing electrical energy, wherein the high-voltage store has a high-voltage store housing, in which a plurality of electrical storage cells are arranged, and a device is provided in the high-voltage store housing through which the gas escaping from one or more of the storage cells into the interior of the high-voltage store housing can escape outwards from the high-voltage store housing into the environment. The device has a purely mechanical acoustic signal generator which is provided in order to generate an acoustic warning signal when gas flows through the device, wherein the warning signal is generated merely by the gas flowing through.

A musical instrument includes a hollow and compressible body made of a flexible and elastic material, delimiting an internal cavity divided into two chambers by an internal wall through which a musical insert is mounted. The body is closed in a sealed manner such that the two chambers are hermetic and communicate only via the musical insert. Said musical insert is designed to emit a sound when passed through by an air flow generated by a mechanical pressure exerted on said body at the level of one of the chambers, which pushes some of the air volume from this chamber into the other chamber through said musical insert. Thus, this musical instrument is said to be clean because it does not need to communicate with the external environment in order to generate a sound, and is perfectly safe.

An electronic whistle system pertains to an electronically activated handheld whistle with a transmitter and receiver modules, for use at various sports games, is disclosed. The transmitter module is configured to send a serialized pulse signal to the receiver module for regulating the start and stop of the game clock. The transmitter module comprises an optical sensor on the opposite side of a vane, which occludes an optical sensor beam when the whistle is blown. A microcontroller sends a serialized pulse signal from the transmitter module to the receiver module. The receiver module intercepts the received signal on the detection of correct serial number, the receiver module will send a STOP pulse to the game clock via a cable. The electronic whistle system is designed to dramatically reduce the errors in the timing aspect of various games.

A drinking container configurable between a drinking configuration and a whistling configuration. The drinking container comprise a main portion defining a liquid receiving cavity and a whistling portion positioned below the main portion and operatively connected thereto. The whistling portion comprises a whistle and is translatable relative to the main portion to configure the drinking container between the drinking configuration and the whistling configuration. When the drinking container is configured in the drinking configuration, a section of the liquid receiving cavity is sealed and prevents fluid communication between the liquid receiving cavity and the whistle while allowing the liquid receiving cavity to hold a liquid therein When the drinking container is configured in the whistling configuration, the section of the liquid receiving cavity is unsealed and allows fluid communication between the liquid receiving cavity and the whistle.
