Abstract
331,044. Fensky, C. May 10, 1929. Hearing - appliances. -A device of the kind described in Specification 225,438 for insertion into the ear contains one or more reeds or flexible members which under the influence of sound waves will vibrate and impart vibrations to the device. A hollow member 13, Fig. 2, has a tapering part 14 ending in a bead 15 for insertion into the ear, and a hollow projection 20 at right angles which may be arcuate and have an opening at the end or in the side wall. A reed 17, Fig. 3, is secured in an opening in the member 13, and projects either into the extension 20 or into the part 14. Alternatively the reed may be secured at the end 15 of the part 14. The projection 20 may be replaced by a short projection 33, Fig. 13, which may be partially closed by a plate or by bending over the side walls 34, 35, so that they overlap.
