    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.

    摘要： The invention concerns digital processing of analog signals in a telephone set. A signal path runs between a telephone line and the handset of the telephone. A digital signal processor is interconnected within this signal path, together with appropriate analog-to-digital, and digital-to-analog, converters. This approach allows digital processing of the information carried by the signal path. The digital processing facilitates, for example, (1) a high degree of separation of the handset's microphone signal from the received signal, and (2) independent control of volumes of the received signal and sidetone.

    摘要： A personal computer (PC) incorporates a speaker/microphone peripheral, which includes a digital-signal-processor (DSP) based acoustic echo canceler and supports a plurality of modes of operation. One mode is a video/telecommunications mode. In this mode, the acoustic echo canceler is enabled and the speaker/microphone peripheral provides a monaural dual speaker and microphone for use in video, internet telephony, etc., communications. Another mode of operation is a multi-media, or wide-band stereo, mode. In this multi-media mode, the acoustic echo canceler is disabled and the stereo loudspeakers provides high fidelity stereo output signals. In addition, in this latter arrangement an optional sub-woofer may be additionally coupled to the stereo loudspeakers. The speaker/microphone peripheral switches between the operating modes by detecting a predefined sequence of dual-tone-multi-frequency (DTMF) digits. The DTMF sequences are played from wave-type files stored on the PC.
