Problems solved by technology

Regrettably, at present, even the high-priced Hi-Fi audio system is difficult to produce ideal effects in residential rooms. use space internal structure
The actual situation is that most of the Hi-Fi audio systems are placed in rooms where the listening environment is not very good, which further increases the difficulty of restoring the sound with a high degree of authenticity, and it is unlikely to produce good sound

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.

Abstract

The invention relates to a method for restore field sound by using a two-channel sound source. In the method, sound boxes are placed in a three-dimensional way, so that micro-sound-field superposition of in-phase components and naturally-reflected heterogeneous components is realized, therefore a three-dimensional large-scale field effect is achieved. In the method, a two-channel sound source is placed in a room, and multiple pairs of sound boxes are placed in cooperation with the two-channel sound source; and the sound boxes are placed in front of listeners in a three-dimensional way, and are connected to a power amplifier in the two-channel sound source in a direct, parallel, serial or series-parallel way. According to the method disclosed by the invention, the defects of poor image false density feel and small scale caused by narrow diffusion of the pair of sound boxes, poor air feel and poor stage feel caused by low diffraction energy and insufficient reflection of a pair of sound boxes, and the like are overcome, the musical feeling of an HiFi (High Fidelity) sound box is improved greatly, and the requirement of a sound box system on a room is lowered greatly.

Description

technical field [0001] The invention relates to sound restoration, in particular to a method for highly authentically restoring live sound by using two-channel sound sources. Background technique [0002] The ultimate goal of the Hi-Fi sound system is to restore the sound of the scene with a high degree of realism, so that a set of sound system can produce a width, height, depth, and sense of position in the room to achieve a realistic sound effect. There are many factors required to achieve the above-mentioned sound effects, the most important of which is the cooperation between the room and the speakers. [0003] According to the current existing technology, although many expensive audio equipment have surprising indicators, their effect is much smaller than the effect produced by the cooperation of the room and the sound box. Regrettably, at present, even the high-priced Hi-Fi audio system is difficult to produce ideal effects in residential rooms. Make good use of ...
