Digital power link audio distribution system and components thereof

An audio distribution system in one embodiment includes a master device, a powered speaker unit, and an expander device. The master device has an output port for receiving a cable carrying an electrical power signal along with a digital audio signal. The speaker unit includes a first port for receiving the electrical power signal and the digital audio power signal, and a second port for sending the signals. A digital-to-analog converter in the speaker unit converts the digital audio signal to an analog audio signal, and a speaker driver uses the signal to produce sound. The expander device is electrically connectable to the second port of the speaker unit for providing electrical power to one or more further speaker units. In another embodiment, the invention provides a master mixer device and a speaker unit. The master mixer device includes a digital signal processor for receiving and separately processing a speech channel having digital audio containing speech content and a music channel having digital audio containing music content. In an embodiment a powered speaker unit employing a class D amplifier for reproducing sound is further disclosed. A digital power link in port is provided in the powered speaker for receiving a cable carrying a digital audio signal and electrical power.

Method for controlling multichannel sound distributing and switching of vehicle-mounted terminal

InactiveCN103686546ASolve the problem of playing different voices at the same time and interacting with each otherIn line with the development directionStereophonic circuit arrangementsHDMISound mixer
The invention discloses a method for controlling multichannel sound distributing and switching of a vehicle-mounted terminal. A software sound mixer comprising a six-path input sound channel and a four-path output sound channel is arranged in the vehicle-mounted terminal; after audio signals of input video accompanying sounds, terminal station reporting sounds and terminal local prompting sounds are mixed through the software sound mixer, the video accompanying sounds and the terminal station reporting sounds are implanted on a left sound channel and a right sound channel of an HDMI signal and played through an audio/video playing device; the terminal local prompting sounds are output to a terminal local power amplifier via another two sound channels, and voice distribution on the vehicle-mounted terminal is achieved; when one video accompanying sound or terminal station reporting sound is played, volume of other audio signals decreases by controlling the software sound mixer and the implantation of and the HDMI or implantation is stopped and recovers the original state after the video accompanying sound or terminal station reporting sound is played, and switching control is achieved. By means of the method, one device can have the function of playing various sounds, and a sound system in the vehicle can be controlled to play various paths of different sounds.
