Embodiment 1

[0103] figure 1 The implementation flow of the sound effect adjustment method provided by the embodiment of the present invention is shown, and the details are as follows:

[0104] In step S101, the number of connected speakers, the orientation angle of the speakers and the distance between the speakers and the listener are detected.

[0105] Specifically, according to the needs of the site conditions or the fault of the line, the number of speakers actually working is sometimes different from the number of speakers connected to the speaker system. In this case, it is necessary to detect the number of speakers connected to the speaker adaptation device . Can be used as follows figure 2 The way shown:

[0106] In step S201, audio analog signals are output on all speaker interfaces.

[0107] Specifically, N speaker interfaces are provided on the speaker adaptation device, and an audio analog signal is output from each speaker interface, that is, a corresponding level signal...

Embodiment 2

[0141] like Figure 8 Shown is a schematic flowchart of the sound effect adjustment provided by the second embodiment of the present invention, and the details are as follows:

[0142] In step S801, the number of connected speakers, the orientation angle of the speakers and the distance between the speakers and the listener are detected.

[0143] In step S802, a corresponding sound field model is selected according to the number of connected speakers.

[0144] In step S803, the sound field transfer function is adjusted according to the distance of the listener and the orientation angle of the speaker according to the sound field model.

[0145] In step S804, the digital audio signal is adjusted according to the sound field transfer function, and the adjusted digital audio signal is output.

[0146] Steps S801-S804 are the same as steps S101-S104 in Embodiment 1, and will not be repeated here.

[0147] In step S805, the reverberation time of the environment space is detected...

Embodiment 3

[0166] Figure 9 The structural diagram of the sound effect adjustment method applied to the audio conference provided by the third embodiment of the present invention is described in detail as follows:

[0167] exist Figure 9 The conference room shown has multiple microphones for speaking, multiple members participating in the conference, and multiple speakers. On the basis of Embodiment 1, the embodiment of the present invention also includes the following steps:

[0168] In step 901, an audio signal inputted by a microphone provided with position information is received.

[0169] The location information of the microphone can be stored in the speaker adaptation device by adding corresponding label information when the microphone is connected.

[0170] In step 902, the location information of the sound box is acquired.

[0171] The position information of the speakers can be input by the user according to the connection situation of the speakers on site in advance, or a ...

Abstract

A sound effect adjusting method and apparatus. The method comprises: detecting the number of connected sound boxes, an orientation angle of a sound box, and a distance between the sound box and an audience (S801); selecting a corresponding sound field model according to the number of connected sound boxes (S802); loading the distance of the audience and the orientation angle of the sound box according to the sound field model, to adjust a sound field transmission function (S803); and adjusting a digital audio signal according to the sound field transmission function, and outputting the adjusted digital audio signal (S804).

Description

technical field [0001] The invention belongs to the field of sound boxes, and in particular relates to a sound effect adjustment method, device and equipment. Background technique [0002] The conventional sound playback device mainly includes a speaker and a speaker adapter device, the speaker is connected to the speaker adapter device, the source sound data or signal is input into the speaker adapter device, and after digital signal processing, the digital audio signal is finally converted into an analog audio signal and sent to the speaker adapter device. The speaker output realizes the conversion of electrical signal to sound signal. [0003] The important indicators for measuring the sound effect of the sound playback device include three-dimensional sense, sense of positioning, sense of space, degree of distortion, subwoofer and treble, etc. Among them, stereo sound refers to the sound with stereoscopic effect. If the whole system can restore the original sense of spa...
