Description
Technical field
The present invention relates to the Radio Transmission Technology between the subwoofer of surround sound, left circulating loudspeaker, right circulating loudspeaker and the main system of audio.
Background technology
Press, general audiovisual surround sound equipment is dialled the audio of putting and is had more telepresenc in order to allow, mostly be to be provided with preposition left and right sound channels loud speaker, center loudspeaker in the place ahead that corresponding to of audio visual environment looked the hearer, be provided with left and right circulating loudspeaker corresponding to the rear of looking the hearer, and subwoofer is set in position, and constitute be commonly called as six sound channels (becoming five one sound channels) around audio.
Again, the erection mode of tradition surround sound is to see through the signal transmission that circuit constitutes each loud speaker and main system of audio, and general main system of audio is located at the anterior position place of looking the hearer more, so the circuit between preposition left and right sound channels loud speaker, center loudspeaker and the main system of audio can't cause obstruction to the moving-wire of audio visual environment; Only, it is located at the moving-wire that the circuit of looking between left and right circulating loudspeaker of having of hearer rear position and the main system of audio then might pass audio visual environment, and will cause obstruction to the personnel of turnover environment, severe patient is more likely because circuit suffers to collude improperly and pulls and cause the damage of stereo set.
So that, the room promptly has as shown in Figure 1, with a left side, right circulating loudspeaker 23,24 carry out the transmission of signal with Wireless transmission mode and main system of audio 10 respectively, by saving a left side, right circulating loudspeaker 23,24 and the line configuring of 10 of main systems of audio, its preposition left side, right channel loudspeaker 21,22, center loudspeaker 26, and subwoofer 2SRU is the transmission that sees through circuit 30 and main system of audio 10 formation signals equally, but its integral device must be at the inside of main system of audio 10 installing signal reflector (not indicating among the figure), and on a left side, right circulating loudspeaker 23,24 inside is provided with signal receiver 40 respectively, and will make the cost of whole stereo set too high, and its left side, right circulating loudspeaker 23,24 more can be because of being equiped with signal receiver 40, and make volume too huge.
Other has as shown in Figure 2, in the inside of right circulating loudspeaker 24 signal receiver 40 is set, constitute the stereo set of left and right circulating loudspeaker 23,24 signals transmission again with circuit 30, configuration by saving one group of signal receiver is in the hope of reducing, the cost of whole stereo set, but it has the uneven shortcoming of left and right circulating loudspeaker 23,24 volumes size; Moreover, as shown in Figure 3, for being equipped with a signal receiver 40 independently in addition, constitute the stereo set of signal receiver 40 and left and right circulating loudspeaker 23,24 signals transmission again by circuit 30, in the hope of solving the big or small uneven problem of left and right circulating loudspeaker 23,24 volumes; Curtain, so configuration mode not only can cause the increase of equipment component, and necessary equally between its subwoofer 25 and the main system of audio 10 by circuit 30 formation signals transmission, therefore still can cause obstruction because of 30 couples of personnel that pass in and out environment of circuit of subwoofer 25.
Summary of the invention
