A respiratory acoustic device is provided that is easy to operate and transport. The device delivers vibrations artificially to the lungs and airways to fluidize mucus adhering to the airways and promote its discharge. A respiratory acoustic deviceis provided with a housing, and a mouthpiecethat is in communication with the housing. The housinghas a reflecting endfor reflecting air that has been blown in from the mouthpieceand an open endthrough which air that has been blown in from the mouthpiececan escape. If a sudden exhalation such as a cough is blown into the housingthrough the mouthpiece, the device causes the noise due to said exhalation to resonate with the oral and lower airway cavities, and vibrate the user's lungs and airways with the low frequency acoustic shock waves generated therein.

Respiratory acoustic device

A vibration absorbed tire is provided which has a laminated structure that contains dilantant layer causing reaction rate differences in the cross-sectional direction and thus functions without impairing the motion characteristics of the tire even with only a single or a few very thin layers, whereby the tire is easy to manufacture and has reduced cost. The tire has the laminated structure, which includes the dilantant layer which is a layer where particles and a bonding material thereof are arranged to act as dilantant, and in which the particles are arranged so that the distribution density of the particles decreases toward the upper and the lower surface from the central part of the layer.

Vibration suppression tire

In an assembly of a pneumatic tire and a rim, in which a tire cavity is formed between the pneumatic tire and the rim by mounting the pneumatic tire on the rim, a noise suppressing body extending in a circumferential direction is disposed inside the tire cavity. The noise suppressing body includes a first sound absorbing material layer arranged apart from an inner surface of a tire tread part through a cavity and a second sound absorbing material layer disposed at the rim side of the first sound absorbing material layer and having lower air permeability than the first sound absorbing material layer.
