FIELD: medical equipment. ^ SUBSTANCE: hearing aid contains piezoelectric transformer (44) and connecting means (54) for connection of transformer with user auricle, transformer being intended for exciting vibrations in auricle in order to induce it to transmit acoustic signal from transformer (44) into user internal ear. Transformer is built into envelope (42) from relatively soft material, envelope is attached to case (34) from relatively hard material in such way that between envelope (42) and case (34) cavity (48) is formed. Additionally claimed is method of hearing aid manufacturing. ^ EFFECT: increasing convenience of using. ^ 18 cl, 8 dwg |
