Abstract: An ear-worn hearing device includes a speaker disposed in a housing comprising a portion configured for wear over, on, or at least partially in a canal of a user's ear. Microphones are integrated with the housing, and a digital signal processing chain is coupled to and located between the microphones and the speaker. The digital signal processing chain includes active noise cancellation (ANC) circuitry configured to generate an anti-noise signal, and speaker-performance-enhancement circuitry coupled to the ANC circuitry and configured to generate a signal based on the anti-noise signal for the speaker. The digital signal processing chain is configured to communicate audio signals between the ANC circuitry and the speaker-performance-enhancement circuitry without changing a format of the audio signals.

Abstract: A micro-speaker for use in hearing and other body worn devices is disclosed, including an acoustic conduit defining an acoustic path between first and second air spaces. A first acoustic transducer is located between the acoustic conduit and the first air space and a second acoustic transducer located between the acoustic conduit and the second air space. The second acoustic transducer is operable to more or less obstruct an acoustic aperture between the acoustic conduit and the second air space, wherein concurrent operation of the first and second acoustic transducers generates an acoustic audio signal that propagates between the first and second air spaces. An acoustic vent between the acoustic conduit and the second air space has an acoustic impedance that is independent of the operation of the second acoustic transducer.

Abstract: A method includes receiving, at a bitline-mux driver circuit, a subarray activation (SUBA) signal and a delay signal. The bitline-mux driver circuit includes a header circuit operable to output a driver voltage to a plurality of driver circuits. The driver voltage is boosted through a voltage divider with diode header circuit based on the SUBA signal to set the driver voltage to a value above a standard supply voltage (VDD) and between a voltage bitline high (VBLH) level and a high voltage (VPP) level. The VPP level exceeds a maximum allowed voltage (VMAX) level of the driver circuits. A master wordline output of the driver circuits is driven to select a bitline mux of a computer memory module based on an address input signal, the delay signal, and the driver voltage.

Abstract: A method for providing file-based media on hold (MOH) services in a Voice over Internet Protocol (VoIP) system includes selecting an MOH file and streaming digital content of the MOH file to a communication device while a call is on hold. If the call is removed from hold and placed back on hold a second time, the digital content of the MOH file is streamed to the communication device while the call is on hold the second time. The digital content is streamed from substantially a beginning of the MOH file to a first stopping point while the call is on hold the first time, and from substantially the first stopping point to a second stopping point while the call is on hold the second time.
