摘要： A transmitter includes a monitoring circuit for monitoring phase transitions of in-phase and quadrature components of an input phase modulated signal. A filter is downstream from the monitoring circuit for generating a filtered phase modulated signal within an allocated bandwidth. A transmit gain controller is downstream from the filter for adjusting an amplitude of the filtered phase modulated signal based on a dynamic reference envelope control signal. A control circuit cooperates with the monitoring circuit and the transmit gain controller for generating the dynamic reference envelope control signal so that phase transitions are suppressed in the filtered phase modulated signal and so that the filtered phase modulated signal remains within the allocated bandwidth.

摘要： A method (100) for matching characteristics of two or more transducer systems (202, 208). The method involving: receiving input signals from a set of said transducer systems; determining if the input signals contain a pre-defined portion of a common signal which is the same at all of said transducer systems; and balancing the characteristics of the transducer systems when it is determined that the input signals contain the pre-determined portion of the common signal.

摘要： Systems and methods for cancelling a near-field noise signal. The methods generally involve: receiving (604), from a first acoustic sensing device (120), a first signal (214) comprising a near-field noise signal (206); synthesizing (320, 420, 520, 606) a replica signal (322, 422, 522) which replicates the near-field noise signal; and communicating (608) the replica signal and the first signal to a far-field noise cancellation process (150). Prior to communicating the replica signal to the far-field noise cancellation process, at least one characteristic of the replica signal is controlled (606) so that the far-field noise cancellation process will identify the near-field noise signal as far-field noise. The far-field noise cancellation process cancels (610) the near-field noise signal and generates (612) an output signal (360, 460, 560) in which the near-field noise signal is reduced in amplitude.

摘要： Modern electronic devices are becoming smaller while the need to critically locate acoustic sensors or transducers, e.g., microphones, is increasing in order to provide improved intelligibility in adverse environments. The acoustic transducers can be used in arrays with their outputs processed in beam forming and noise cancellation algorithms. The use and creation of features on the surface of a small package to deal with the problem of achieving high performance solutions in a limited space are disclosed herein. For example, embodiments of electronic communication devices (10) include acoustic transducers (26) integrated with other features such as a volume control (34, 50), an antenna (87, 260, 280), an adapter (300) which can be coupled to an input/output jack (90) and an accessory connector, or a projection (98).

摘要： A system is provided to protect a loudspeaker (144) by controlling a level of an applied audio signal. A control signal is generated by applying an input audio signal (115) to the collective operations of a gain control system (100). The gain control system (100) uses the input audio signal (115) in conjunction with at least one parameter to derive an estimated stress associated with the loudspeaker (144). The estimated stress is compared with a protection threshold stress (127). If the protection threshold stress is exceeded, a gain applied by a gain component (134) is selectively adjusted to modify the input audio signal (115). The resulting gain-controlled audio signal (116) is employed to drive the loudspeaker (144).
