An outdoor tool with multiple functions may comprise a handle, a spring clip, a blade, a cover and a flint rod. When the blade is in a folded position, it is coupled with the spring clip, and an actuating segment of the spring clip can tightly clamp the blade. Furthermore, when blade is in a deployed position, a mounting piece of the blade is mounted on a mounting hole of the spring clip thereby improving the structural stableness. In addition to cutting objects, the outdoor tool also can be used for whistling, starting a fire, opening a bottle, scraping fish scale, sharpening a knife thereby improving the practicability.

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.

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.

An inhaler or add-on device for an inhaler for dispensing a medicament to be inhaled. The inhaler or add-on device has a housing (H) with an air inlet (A_I), and an air outlet (A_O) for outputting air to be inhaled by a user. The housing (H) defines a flow path (FP) between the air inlet (A_I) and air outlet (A_O), and a passive acoustic element (PAE) is arranged in this flow path (FP) inside the housing (H). The passive acoustic element (PAE) has a structure having one or more structured gaps arranged to be passed by an air flow and it is dimensioned such that air flow passing it will generate sound (S) with pre-determined characteristics depending on the air flow speed. This allows acoustic monitoring of air flow passing the first passive acoustic element (PAE) external to the housing (H) by capturing and processing sound generated.

There is disclosed a balloon holder for holding a balloon having a tail and a tapered self-closing bladder. The balloon holder comprises a main body having a tail locking mechanism, an elongated member protruding from a bottom extremity of the main body, a support element configured to slide over the elongated member and be positioned on the main body, and a position adjustment mechanism for adjusting the position of the support element on the main body. In use, the tail of the balloon is secured to the main body by the tail locking mechanism and the support element is slid over the elongated member and positioned on the main body using the position adjustment mechanism so as to support the balloon in an upright position.

A pet toy includes a core having interior portion and defining an elongate channel along a surface of the core, a channel-shaped insert received into the elongate channel and overlying the elongate channel, a cover attached to the channel-shaped insert, and overlying portions of the core that are not covered by the channel-shaped insert such that the core is enclosed cooperatively by the channel-shaped insert and the cover, and a noise making device disposed within the interior portion of the core.
