摘要: In various embodiments, vibro-acoustic transducer arrangements in accordance herewith are optimized for sensing and transducing acoustic phenomena occurring within a patient's body, and manifesting themselves at the skin surface with frequencies ranging from 0.001 Hz to 10 kHz. Strategies for effectively coupling to the skin include judicious mismatching of mechanical impedance, the use of impedance-matching gels or liquids, a shaped (e.g., domed) pickup, material selection, and/or a peripheral leaf-spring arrangement permitting relative movement between inner and peripheral diaphragm portions. The spring stiffness or spring compliance of the leaf springs may be selectively chosen to optimize the frequency response of the sensor.

摘要: A motor is disclosed. The motor includes a stator with a stator coil to generate a periodic unidirectional field current flowing through the stator coil and a rotor. An air gap is disposed between the stator and the rotor. The rotor has at least one rotor ring, a portion of the rotor ring is disposed in the air gap. Due to the unidirectional magnetic field, a periodic electric current is induced in the rotor ring. The electric current flowing through the portion of the rotor ring disposed in the air gap flows in a first direction to rotate the rotor relative to the stator.

摘要: An electromagnetic voice coil actuator comprises a pot core magnet structure having a magnetic flux conductive core, a field coil within the pot core magnet structure for generating magnetic field through the magnetic flux conductive core and across an air gap, a voice coil disposed within the air gap. The voice coil and the field coil are each driven by an amplified signal derived from the audio input signal to create an actuation force, wherein the pot core magnet structure uses a soft magnet core.
