摘要： An electro acoustic transducer has a housing having an axial threaded bore. A transducer driver element is axially aligned in the bore and has a first end mounted on an electrically conductive holder that is axially displaceable by a conductive screw member. A hemisphere on the other end of the driver element contacts a diaphragm for radiating acoustic signals. An electrical connector has a conductive coil spring coupled to the screw member and is electrically connected to the first end of the driver element via the coil spring, screw member, holder, and mounting plug. Another electrical connector is connected to the other end of the driver element via a conductive front plate, diaphragm, and hemisphere in one embodiment or a flexible lead in another embodiment. In both embodiments, the electrical connectors couple electrical driving signals to the driver elements to cause the driver elements to mechanically vibrate.

摘要： A method of manufacturing multiple dimension transducer arrays of multiple layer elements from modules is provided. A plurality of multiple layer strips are formed. The strips are separate, such as an elongated strip corresponding in size to one row of elements. Connections between the electrodes of various layers or separate connections from the various electrodes to a bottom of the strip are formed on the separate multiple layer strips. The separate strips are then aligned within a frame and bonded together. The resulting sheet of multiple layer transducer material is then diced to form elements. Due to the previous interconnection of electrodes, each element includes electrical connections for each of the layer electrodes, avoiding the need for vias or high aspect ratio sputtering.

摘要： A method of forming an electrode pattern of a surface acoustic wave device easily and reliably prevents the occurrence of an abnormality in the shape of a resist pattern. In the electrode pattern forming method, a resist layer is formed on a top surface of a piezoelectric substrate, and then exposed to ultraviolet rays through a photomask provided above the top surface of the piezoelectric substrate to form a resist pattern on the surface of the piezoelectric substrate. Furthermore, a conductor film is formed on the top surface of the piezoelectric substrate, and the resist pattern is removed by a liftoff method to form an electrode pattern of the surface acoustic wave device. Exposure is performed using ultraviolet rays having a wavelength which is completely absorbed into the piezoelectric substrate without reaching the bottom surface of the piezoelectric substrate.

摘要： A microfabricated acoustic transducer with suppressed substrate modes includes a diaphragm containing an upper electrode suspended above a substrate containing a lower electrode; the substrate may or may not contain electronic circuits. The substrate modes are suppressed by either thinning the substrate such that a longitudinal ringing mode occurs outside of the frequency band of interest or applying a judiciously designed damping material that absorbs acoustic energy from the substrate on the backside of the transducer substrate, or by both thinning the substrate and applying the damping material. The damping material has an acoustic impedance that matches the acoustic impedance of the substrate and is lossy.
