摘要： A horn for use with a loudspeaker may include an entrance disposed at a first axial end of the horn and configured to receive a driver. A mouth may be disposed at a second axial end of the horn opposite the entrance. A contoured surface may extend between the entrance and the mouth. A cross sectional shape of a coverage pattern of audible sound emitted by the loudspeaker coupled with the horn may be independent of a shape of the entrance and a shape of the mouth.

摘要： A system that includes a talker, a listener, and a controller may communicate over an Ethernet Audio/Video Bridging network. The controller may communicate control messages to manage data streams between the talker and the listener through one or more application layer interfaces of the talker and the listener. Based on the control messages, the talker and the listener may communicate using a Stream Reservation Protocol to reserve connection for, or remove connection from, the data streams. The talker and listener may communicate the success of reserving or removing the connections to the controller through the application layer interfaces.

摘要： A system generates one or more media streams from time-stamped packets received over a network. The packets may include audio, video, or a combination of both, sampled at a rate determined by a master media clock at a transmitter of the time-stamped packets or at some other node on the network. Timestamps in the packets may be presentation times based on values of a remote real-time clock at the transmitter that is synchronized with a local real¬ time clock at a receiver. The system may generate the media streams from the media stream samples and present the sampled data according to the presentation times.

摘要： An automated audio tuning system may optimize an audio system for power efficiency when performing automated tuning of the audio system to optimize acoustic performance. The system may establish any number of different power efficiency weighting factors to provide a balance between acoustic performance and power efficiency during operation. The power efficiency weighting factors may range from representing optimizing power efficiency with constrained optimization of acoustic performance to optimized acoustic performance with minimized regard for power efficiency. For each of the efficiency weighting factors, the system may generate operational parameters, such as filter parameters, to achieve a target acoustic response while maintaining a determined level of power efficiency.

摘要： An amplifier (300) having improved distortion characteristics is set forth. The amplifier (300) includes an interleaved PWM amplifier that generates interleaved PWM pulses in response to a modified input signal (325) and one or more carrier signals (390). The interleaved PWM pulses of the amplifier (300) are used to drive a power stage (315), such as an opposed current power stage. The amplifier (300) also includes an interleaved PWM generator (370) that provides interleaved PWM pulses in response to the modified input signal (325) and one or more further carrier signals (390). The carrier signals used by the PWM generator (370) may differ in phase from the carrier signals used by the interleaved PWM amplifier (305) to generate its interleaved PWM pulses. One or more feedback circuits (350, 375) are employed in the generation of the modified input signal. (325) More particularly, the feedback circuit (s) generates the modified input signal (325) based on an input signal (360) that is to be amplified and the interleaved PWM pulses of the interleaved PWM generator (470).

摘要： A loudspeaker cone body made of plastic includes a base carrier material and a filler material. The base carrier material is selected to optimize overall flow, weight and stiffness. The filler material may be a nanomaterial that provides for adjustment of process and acoustic related characteristics in the loudspeaker cone body that become relevant when the loudspeaker cone body is operated in a loudspeaker. Acoustic related characteristics that may be adjusted include a stiffness to weight ratio and an acoustic damping of the loudspeaker cone body. A predetermined weight percent of the filler material may be combined with the base carrier material to obtain repeatable desired acoustic related characteristics. The acoustic related characteristics may be adjusted by changing the predetermined weight percent of the filler material.

摘要： Sound processing systems have been developed that create a surround effect without quality degradation experienced by known sound processing systems in non-optimum listening environments. The sound processing systems may include matrix decoding systems that manipulate input signals prior to converting them into a number of input signals. These sound processing systems may also alternately include a bass management system that from the input signals preserves the low frequency components of the input signals in separate channels. Both the matrix decoding systems and bass management systems may also produce additional signals. Further, the matrix decoding and bass management systems may be implemented separately or jointly in vehicular sound systems.

摘要： A method and system (100) are provided for generating one or more mix coefficients (ml, mr) for downmixing a multichannel input signal having a plurality of input channels (LI, CI, RI), to an output signal having a plurality of output channels (LO, RO). Mix coefficients may be generated responsive to a comparison of energy between the downmixed (output) signal and the input signal to the downmixer (100), such that energy and intended direction of the input signal are substantially preserved in the output signal. Further, the mix coefficient generation may preserve an intended direction of an input signal, for example, received at a surround input channel, in at least one output channel of the output signal. The mix coefficient values (ml', mr') may be generated in a test downmixter (104) environment. Additionally , one or more mix coefficients may be generated by retrieving predetermined mix coefficient values.
