    摘要： A monolithic second order gradient (SOG) microphone structure employs acoustic transmission lines wherein the acoustic phase delay along each of the acoustic transmission lines is in direct proportion to the length of each of the acoustic transmission lines and, where this is effected by the use of an acoustic impedance element placed within each acoustic transmission line that has an acoustic impedance related to the acoustic impedance of the associated acoustic transmission line. In one embodiment, the acoustic impedance element has a specific acoustic impedance substantially matched to the specific acoustic characteristic resistance of the acoustic transmission line. Various embodiments may utilize acoustic or electrical subtraction of the signals in the acoustic transmission lines to realize the desired directional sound pickup.

    摘要： An improved Broadside SOG microphone assembly is realized by employing a microphone assembly having at least three ports arranged in a non-colinear fashion with the at least three ports defining and being in a "gradient" plane and with both outer adjacent differential pair of ports aligned in a direction substantially toward a prospective talker's lips. Thus, the inner port(s) is always closer to the prospective talker's lips. Each outer differential pair of ports forms a dipole which yields a high spatial gradient and, hence, higher speech sensitivity since they are pointed substantially toward the prospective talker's lips. Just as important, as the prospective talker's lip position relative to the microphone varies, this alignment of each outer differential pair of ports will result in the least change in the dipole sensitivity and, therefore, the lowest Broadside SOG microphone position sensitivity. Another advantage of this arrangement is that it similarly has significantly reduced position sensitivity with angular departure from the nominal Broadside prospective talker's lip position, owing again to the orientation of the prospective talker's lips. In a preferred embodiment, a single FOG microphone element is employed which accepts four distinct acoustic signals from acoustic transmission lines from four distinct ports arranged in a non-colinear fashion. The four ports define and are in a "gradient" plane with both outer adjacent differential pair of ports aligned in a direction substantially toward the prospective talker's lips. Thus, the inner ports are always closer to the prospective talker's lips. Each outer differential pair of ports forms a dipole which yields a high spatial gradient and, hence, higher speech sensitivity since they are pointed in a direction substantially toward the prospective talker's lips. To this end, the outer ports are plus (+) ports and the inner ports are minus (-) ports, or vice versa, referring to each side of the FOG element's diaphragm.

    摘要： An electroacoustic transducer in accordance with the present invention comprises a perforated backplate having a plurality of upstanding parallel ribs between which conductive surfaces are situated. The conductive surfaces are electrically interconnected with one another and with a contact surface on a relieved shoulder at one end of the backplate. This shoulder is engaged by a bifurcated contact spring that (1) electrically connects the conductive surfaces to the input of an integrated preamplifier circuit deposited on a substrate and (2) holds the substrate in place on the underside of the backplate.An electret diaphragm having a metallized surface is tensioned across the ribs of the backplate with the metallized surface facing away from the backplate, and while so tensioned, the ends of the diaphragm are clamped against the backplate by a conductive intermediate member that makes electrical contact with the diaphragm. The intermediate member is held in place by a conductive spring member that wraps around the sides of the foregoing assembly and presses the intermediate member and the substrate toward one another. The spring member provides the clamping force necessary to retain the desired tension on the diaphragm and at the same time further secures the substrate in place. In addition, the spring member includes a terminal that is located in engagement with the ground lead of the preamplifier circuit and thus in combination with the intermediate member provides a conductive path to ground for the conductive surface of the diaphragm. Finally, the spring member serves to provide additional electrostatic shielding for the electret.

    摘要： A moving-armature transducer assembly suitable for use as an alerter in a portable telephone. The assembly includes a transducer housed in an enclosure including first and second acoustical chambers. A first sound emitted from a front hole on a front side of the transducer is propagated through the first acoustical chamber and emitted from a first port of the assembly. A second sound emitted from a rear hole on a rear side of the transducer is phase-shifted by the second acoustical chamber acting in combination with a second port or ports on the assembly to have a phase coinciding with the phase of the first sound. The second sound then combines with the first sound, reinforcing the first sound and producing a combined sound having an increased level and bandwidth.

    摘要： An omnidirectional electret condenser microphone element with improved low frequency background ambient acoustical noise rejection is provided. The omnidirectional electret condenser microphone element includes a plurality of passageways in acoustic series that couple at least one acoustic aperture of the microphone element to an acoustic cavity formed within the microphone element. At least one of said plurality of passageways is of a predefined size that is determined to provide the desired response roll-off within a predefined frequency range. In at least one preferred configuration, the roll-off resulting from the plurality of passageways is greater than 2.0 dB between 300 and 100 Hz. In at least one alternate preferred configuration, the roll-off resulting from the plurality of passageways is greater than 3.0 dB between 300 and 100 Hz.

    摘要： A direction finder arrangement advantageously employs a plurality of transducers to derive a plurality of predetermined polar directivity patterns each of which has a predetermined spatial orientation pointing in a predetermined fixed direction relative to each of the other polar directivity patterns. The polar directivity patterns detect a plurality of amplitude values of a propagating wave approaching at different angles relative to the plurality of spatially oriented polar directivity patterns. Then, the detected wave amplitude values are processed to determine an estimate of a direction toward the source of the arriving wave. More specifically, the detected amplitude values are processed to obtain an estimate of the directional orientation of a hypothetical polar directivity pattern pointing toward the source of the arriving wave.
