摘要： A speech aid apparatus for laryngectomees includes a first housing having disposed therein, a sound head with a hard diaphragm held therein, an electrodynamic oscillator connected to the sound head and including a magnet system with an oscillator coil, a plunger connected thereto and a soft diaphragm vibrationally connected to the first housing through the plunger whereby the soft diaphragm sets the hard diaphragm into vibration. The apparatus also includes a second housing for a power supply and an operating switch and the two housings are releasably mechanically and electrically connected by a bayonet joint. The magnet system includes a pot type magnetic arrangement with an axially polarized very thin annular permanent magnet held between two pole rings made of a soft magnetic material and having rotational symmetry. The upper pole ring is pot shaped with a downwardly open annular gap concentric with the central opening of the magnet arrangement and the oscillator coil projects into the annular gap. The plunger is connected to the oscillator coil and extends freely through the central opening of the magnet arrangement.

摘要： Motor vehicle wheel including a wheel rim and a tire having a tire interior enclosed by the wheel rim and the tire. The tire is mounted on the wheel rim, and the wheel also includes an insert composed of a ring-shaped sound-absorbing material that is positioned within the tire interior. The wheel further includes an acoustically transparent support element having tensile strength, at least in a circumferential direction of the tire, that is coupled to the insert.
