Embodiment 1
[0021] Such as figure 1 As shown, this embodiment takes three pairs of speakers as an example, and a two-channel audio source is placed in the room, and the two-channel audio source includes a signal source (such as a CD player) and a two-channel pre-amplifier. The two-channel audio source also includes 6 mono-channel post-stage power amplifiers with gain control connected after the two-channel pre-amplifier, or it can be 3 dual-channel post-stage power amplifiers or a 6-channel post power amplifier. Three pairs of speakers are placed in conjunction with the two-channel sound source, and the three pairs of speakers are respectively the first speaker, the second speaker, and the third speaker according to the distance from the listener. The two first speakers are placed symmetrically in front of the listener, the two third speakers are placed higher than the first speakers and the second speakers, and can be directly hung on the wall, and the second speakers are placed on the ...
Embodiment 2
[0025] Such as figure 2 shown. This embodiment takes 3 pairs of speakers as an example, which are similar in structure and connection to Embodiment 1. A two-channel sound source is placed in the room, and the two-channel sound source includes a signal source (such as a CD player) and a two-channel sound source. Preamplifier. The two-channel audio source also includes 6 mono-channel post-stage power amplifiers with gain control connected after the two-channel pre-amplifier (it can also be 3 dual-channel post-stage power amplifiers or a 6-channel Post-stage power amplifier) and cooperate with the two-channel sound source to place 3 pairs of speakers. The 3 pairs of speakers are respectively the first speaker, the second speaker and the third speaker according to the distance from the listener.
[0026] The difference between this embodiment and Embodiment 1 is that the wiring of the second speaker is opposite to that of Embodiment 1, and the orientation of the second speake...
Embodiment 3
[0029] Such as image 3 and Figure 4 As shown, the present embodiment takes 3 pairs of speakers as an example. It is to place a two-channel sound source in the room. The two-channel sound source includes a signal source (such as a CD player) and a two-channel power amplifier, and cooperates with the two Three pairs of speakers are placed on the sound source of the channel, and the three pairs of speakers are respectively the first speaker, the second speaker and the third speaker according to the distance from the listener.
[0030] Three pairs of speakers are connected in parallel with the same phase and then connected to the power amplifier. The three pairs of speakers should use high-impedance speakers (such as 16 ohms). The first speaker should use high-sensitivity speakers, and the second and third speakers should use low-sensitivity speakers. The placement of the speakers is similar to that of Embodiment 1 and Embodiment 2.
