Abstract
A component having an acoustically active material, whose acoustic constants can be at least partially altered. The acoustically active material is located at least partially at a phase transition point and/or in the vicinity of a phase transition point.
Claims10
Component having an acoustically active material (2) whose acoustic constants are modifiable at least in part, characterized in that
- the acoustically active material is located at least in part at a phase transition point and/or in the vicinity of a phase transition point.
Component according to at least one of the preceding claims, characterized in that
- one part of the acoustically active material (2) is situated in the one phase while another part of the acoustically active material (2) is situated in the other phase.
Component according to at least one of the preceding claims, characterized in that
- the component (1) contains means (3, 4, 5) for modifying the acoustic constants of the acoustically active material and/or connections for such means.
Component according to at least one of the preceding claims, characterized in that
- the component (1) is a surface acoustic wave component, a bulk acoustic wave component and/or a diaphragm resonator.
Component according to at least one of the preceding claims, characterized in that the component (1) is a filter.
Method for the operation of a component (1) having an acoustically active material (2), whereby
- the acoustic constants of the acoustically active material (2) are modified, and
- the acoustically active material (2) is operated at least in part at a phase transition point and/or in the vicinity of a phase transition point.
