Beschreibung
Zusammenfassung:	A device is provided that comprises a membrane that includes one or more layers of an electrically resistive material. The device also comprises a film disposed along a surface of the membrane to form a coil. The film includes one or more layers of an electrically conductive material. The device also comprises a support structure coupled to a periphery of the membrane. The device also comprises a magnet arranged to provide a magnetic field that is substantially parallel to the surface of the membrane. The device also comprises a signal conditioner configured to provide an electrical signal to the coil to generate an electrical current flowing through the coil. The electrical current interacts with the magnetic field to cause a vibration of the membrane. Characteristics of the vibration are based on at least the electrical signal provided by the signal conditioner.
