摘要： An economical and compact dual-chamber loudspeaker includes a small driver received within a partition extending between, and in acoustical and pneumatic communication with, both a front and a back chamber, each of which has a relatively small volume. An elongated vent is in acoustical and pneumatic communication between the front and back chamber at a substantially planar opening in the partition. The drone cone is in acoustical and pneumatic communication between the front chamber and the outside environment at a substantially planar opening in the housing. The two openings are spaced apart and generally parallel to each other. In a preferred embodiment, the volume of the chambers is minimized by securing an elongated concentric vent around the vent extending between the front and back chambers. In an alternative preferred embodiment, there are at least two elongated vents in acoustical and pneumatic communication with the front and back chambers, and each vent is spaced equal distance from the driver and from each other such that they distribute the pneumatic loads between the front and back chambers evenly, thereby preventing pneumatic forces emanating from the vents from applying asymmetric force to the drone cone.

摘要： A speaker that includes a pair of spaced-apart, in-plane mounted drivers connected in series to a network for applying the appropriate frequency component of the electrical input drive signal to each of the drivers is disclosed. A frequency dependent shunting network, such as a low pass filter, is applied to one of the drivers so as to gradually mute the one driver as a desired frequency is approached. The result is an aesthetically pleasing speaker that has dual in-plane drivers and that produces superior sound quality throughout the entire frequency range of the speaker, including those ranges in which dual, in plane, drivers tend to acoustically interfere with each other.

摘要： A multimedia computer speaker system includes a pair of amplifiers that provide amplified right and left audio signals to a pair of wide-band speakers. The amplifiers are configured to provide the amplified right and left audio signals that are out of phase with each other. The amplified right and left audio signals are applied to opposite terminals of the two wide-band speakers. These reversed terminal couplings to the wide-band speakers of the phase-reversed signals provide phase-aligned right and left audio playback at the speakers. A subwoofer and a low pass filter are connected as a bridge-tied load to receive the amplified right and left audio signals. The phase of one amplified audio signal is in effect reversed by applying it to the negative terminal of the subwoofer. As a result, low frequency components of a phase reversed amplified audio signal are summed by the subwoofer with low frequency components of the other amplified audio signal to provide a low frequency audio playback.

摘要： A subscriber unit (100) determines that there is information to transmit, and requests an amount of bandwidth. Upon receipt of the request for bandwidth from the subscriber unit, the fixed network equipment (FNE; 102) determines whether the requested bandwidth is available. If yes, the FNE dynamically determines at least a first timer value to be used by the subscriber unit to detect a loss of granted bandwidth, and transmits a reservation grant to the subscriber unit granting the request. The reservation grant comprises the at least first timer value. Upon receipt of the reservation grant, the subscriber unit extracts the at least first timer value from the reservation grant and uses the at least first timer value to detect loss of granted bandwidth.
