| 摘要 |
The invention is an improved stethoscope head having a conical shell-like head for improved acoustic detection and transmission. In its preferred embodiment, a stethoscope head may be constructed from a sea shell having a relatively broad, generally circular aperture defining a sound chamber opening, said chamber having a naturally polished, sound reflecting, interior surface. The interior surface defines a conical acoustic chamber having a generally helical axis resulting in a deep, yet compact chamber which increases the effective sound power radiated along the axis as acoustic waves propagate thereby functioning as an acoustic transformer and enhancing the fidelity of the received signal while masking unwanted sounds produced by the anatomy.
