DEFINITION

Classification: 369/155

Mechanical conversion to or from sound:

(under subclass 127) Subject matter wherein the storage medium sensing or modulating element is mechanically coupled to a sound transmitting or responsive solid element (e.g., diaphragm), so as to directly couple the elements.

(1) Note. The sensing or modulating element is usually in physical contact with the storage element.

(2) Note. The term "mechanical" includes a fluidic coupling.

(3) Note. Such devices with sound boxes or acoustical tone arms are classified here, however, the subcombination limited thereto are classified in the indented subclasses 157-169.
