In this embodiment, in step 102, setting the equalizer parameters of each loudspeaker box according to the acoustic characteristic parameters of each loudspeaker box includes: the method comprises the steps of comparing characteristic parameters of all the sound boxes, and determining frequency bands where all the sound boxes are played relatively or absolutely best according to comparison results, so that equalizer parameters of all the sound boxes are set, wherein an Equalizer (EQ) can be used for adjusting gain (db) of signals of all the frequency bands, the EQ parameters in the sound boxes can be represented in a graph or numerical form, namely the equalizer can divide output of the sound boxes into a plurality of frequency bands, and output gain of each frequency band is set respectively.
In this embodiment, in step 102, when it is determined that the performance of one loudspeaker box in the predetermined frequency band is higher than the threshold or higher than the performance of other loudspeaker boxes in the predetermined frequency band according to the acoustic characteristic parameters, the equalizer parameter of the one loudspeaker box is set to enhance the signal in the predetermined frequency band, and suppress the signals in other frequency bands except for the predetermined frequency band, where the threshold and the predetermined frequency band may be set as needed, for example, the predetermined frequency band includes a low frequency, an intermediate frequency, a high frequency, or an ultra-low frequency, a sub-low frequency, an intermediate frequency, a sub-high frequency, an ultra-high frequency, and the like, and the frequency range of each frequency band may refer to the specification of the prior art.
In this embodiment, it may be determined that the performance of the sound box in the predetermined frequency band is higher than the threshold or higher than the performance of other sound boxes in the predetermined frequency band by calculating the frequency attenuation of the signal in the predetermined frequency band, and when the attenuation is smaller than a certain value, it indicates that the performance of the predetermined frequency band is higher than the threshold, that is, the smaller the attenuation value is, the better the performance of the frequency band is, and by inputting the same test audio signal with flat frequency characteristics to each sound box, acquiring the audio signal sent by each sound box in a mute room, to obtain a frequency-amplitude curve (acoustic characteristic parameter) of each sound box, and determining that the attenuation of one sound box in the predetermined frequency band is smaller than the certain value or smaller than the attenuation of other sound.

For example, it is determined that the performance of the sound box a at low frequency is higher than the threshold value for the acoustic characteristic parameters of the sound boxes a, B, and C, optionally, when the performance of the sound box a at low frequency is better than the performance of the sound box B or the sound box C at low frequency (that is, for the same section of test audio signal, the attenuation of the sound box a at low frequency is less than the attenuation of the sound boxes B and C at low frequency), that is, the sound box a is good at playing low frequency signals, the EQ parameter of the sound box a may be set to enhance the low frequency and suppress signals at other frequencies; determining that the performance of the sound box B at high frequency is higher than the threshold, optionally, when the performance of the sound box B at high frequency is better than that of the sound box a or the sound box C at high frequency (that is, for the same section of test audio signal, the attenuation of the sound box B at high frequency is smaller than that of the sound boxes a and C at high frequency), that is, the sound box B is good at playing high frequency signals, and the EQ parameter of the sound box B can be set to enhance the high frequency to suppress signals of other frequencies; it is determined that the performance of the sound box C at the intermediate frequency is higher than the threshold, optionally, when the performance of the sound box C at the intermediate frequency is better than that of the sound box a or the sound box B at the intermediate frequency (that is, for the same section of test audio signal, the attenuation of the sound box C at the intermediate frequency is smaller than that of the sound boxes a and B at the intermediate frequency), that is, the sound box C is good at playing the intermediate frequency signal, and the EQ parameter of the sound box C may be set to enhance the intermediate frequency to suppress signals of other frequencies.
Fig. 2A to 2C are schematic diagrams of EQ parameters set for speakers a, B, and C, respectively, and as shown in fig. 2A to 2C, the EQ parameters are represented by curves, from left to right, the frequency represented by the abscissa increases, the ordinate represents the gain, and the EQ parameters of the speaker a are curves for enhancing the low frequency and suppressing other frequencies; the EQ parameter of the sound box B is a curve for enhancing high frequency and inhibiting other frequencies; the EQ parameters of the sound box C are curves for enhancing the intermediate frequency and suppressing other frequencies, and each sound box a, B, C can synchronously play the same audio frequency according to its own EQ curve, that is, the sound box a mainly plays the low frequency signal in the audio frequency, the sound box B mainly plays the high frequency signal in the audio frequency, and the sound box C mainly plays the intermediate frequency signal in the audio frequency.
In this embodiment, in step 102, optionally, for each loudspeaker box, one or more sets of equalizer parameters may be set according to the acoustic characteristic parameters, for example, when it is determined that the performance of the loudspeaker box in the predetermined frequency band is higher than the threshold value according to the acoustic characteristic parameters, multiple sets of equalizer parameters are set, each set of equalizer parameters is set to enhance the signal in the predetermined frequency band, and suppress the signals in other frequency bands except the predetermined frequency band, but the gain for enhancing or suppressing each set of equalizer parameters is different.

In this embodiment, optionally, each sound box may embed one or more sets of equalizer parameters in each sound box in advance, and when playing audio, directly process the audio to be played according to one set of equalizer parameters, and play the audio synchronously with other sound boxes; however, this embodiment is not limited to this, for example, the equalizer parameters may not be pre-built, that is, each loudspeaker box may also play audio synchronously according to the equalizer parameters set by negotiation via the network, or other loudspeaker boxes, or electronic devices.
According to the embodiment, the acoustic characteristic parameters of each sound box in the plurality of sound boxes are respectively obtained; the equalizer parameters of each sound box are set according to the acoustic characteristic parameters of each sound box, so that when a plurality of sound boxes synchronously play audio, each sound box plays a frequency band signal which is good at, the playing tone quality is optimized, the optimal combined sound effect is obtained, and the listening experience is improved.
