Step S101, acquiring information of a wakeup mode of a wireless sound box, where the wakeup mode comprises: a speech wakeup mode and a non-speech wakeup mode;
In this embodiment, the wireless sound box may be a sound box adopting wireless connection to realize the signal transmission. The wireless sound box may comprise a Bluetooth wireless sound box, a Wi-Fi wireless sound box, an FM the wireless sound box, etc.
Optionally, the speech wakeup mode of the first embodiment of the present application may be collecting a speech signal and detecting whether the speech signal contains a speech wakeup information, if the speech wakeup information is contained, the wireless sound box is waken up.
Optionally, the non-speech wakeup mode of the first embodiment of the present application may comprise: a mode where wakeup is triggered by a button, and a mode where a wakeup function is turned off, of which, the mode where wakeup is triggered by the button may comprise collecting a button signal and detecting whether the button signal contains a preset button wakeup information, if the button signal contains the preset button wakeup information, the wireless sound box is waken up. Exemplarily, under the mode where the wakeup function is turned off, the wireless sound box may be used to display an audio, such as music.
Step S102, configuring an equalizer parameter of the wireless sound box according to the information of the wakeup mode, where said configuring an equalizer parameter of the wireless sound box according to the information of the wakeup mode comprises: configuring, under the speech wakeup mode, the equalizer parameter to be a first mode parameter for regulating a nonlinear distortion, and configuring, under the non-speech wakeup mode, the equalizer parameter into a second mode parameter for regulating an output sound effect.
In the first embodiment of the present application, the equalizer is a module configured for separately regulating an amplification of electrical signals of various frequency components in the wireless sound box, and compensating the defects of the speakers and the sound field and compensating and modifying various sound sources, etc. by regulating the electrical signals of different frequencies. In the first embodiment of the present application, the nonlinear distortion may be a nonlinear distortion produced by an output audio relative to an original audio. The nonlinear distortion may comprise a harmonic distortion, a clipping distortion, an intermodulation distortion, etc. When an original speech signal passes through an amplifier, in addition to an amplified input component, an output signal further includes a two-fold, three-fold, four-fold, or even much higher frequency components, which are called harmonic. While harmonic distortion refers to distortion caused by harmonic, which can be expressed by a ratio of the root mean square (rms) value of a target harmonic (second-order, third-order, etc.) to the rms value of an original frequency signal.
Optionally, in the first embodiment of the present application, the operation of configuring, under the speech wakeup mode, the equalizer parameter to be the first mode parameter for regulating the nonlinear distortion may comprise regulating a gain of a first preset frequency to a first predetermined value and/or lowering a low frequency output power to a second predetermined value under the speech wakeup mode, where the first preset frequency comprises at least one frequency band and/or at least one frequency, and the first predetermined value comprises a set of predetermined gain multiples corresponding to various frequency bands and/or various frequencies, respectively.
Exemplarily, the first preset frequency may be a continuous frequency band, for example, it may be a frequency band other than a low frequency, such as a frequency band above 150 Hz, in such case, the first predetermined value is a predetermined value of a gain multiple corresponding to the continuous frequency band. The first preset frequency band may also be a plurality of segmented frequency bands and/or single frequencies or a set of the plurality of segmented frequency bands and the single frequencies, in such case, the first predetermined value may be a set of predetermined gain multiples corresponding to the plurality of segmented frequency bands and/or single frequencies, respectively. By setting the gain values corresponding to different frequencies or frequency bands respectively, it is possible to regulate the gain of the frequency and the frequency band which are prone to nonlinear distortion, thereby reducing the nonlinear distortion. In addition, exemplarily, for a sound box equipped with a passive basin or an active woofer, the nonlinear output of the sound box can be reduced by lowering the low frequency output power to the second predetermined value, thereby alleviating vibration of the body of the wireless sound box caused by the relatively high low-frequency component, thereby reducing the interference of the speech signal and improving the recognition rate of the speech.
Optionally, in the first embodiment of the present application, the operation of configuring, under the non-speech wakeup mode, the equalizer parameter to be the second mode parameter for regulating the output sound effect may comprise regulating gains of various frequency signals to predetermined standard values and/or regulating output powers of the various frequency signals to rated output frequencies under the non-speech wakeup mode.
The standard values corresponding to the various frequency signals may be the same or different, the predetermined standard values may be a set of standard values corresponding to the various single frequency signals. By regulating the gains of the various frequency signals to the predetermined standard values and/or regulating the output powers of the various frequency signals to the rated output frequencies, the defects of the sound field of the speaker can be compensated by regulating the various different frequency signals, thereby realizing the enhancement and modification of various sound source and other particular purposes.

In the first embodiment of the present application, by configuring different equalizer parameters according to different wakeup modes of the wireless sound box, the accuracy of speech recognition can be improved while improving the sound quality of the wireless sound box, thereby being adapted to the needs of different application scenarios, and possessing relatively high practicality and usability.
Step S201, acquiring information of a wakeup mode of a wireless sound box, where the wakeup mode comprises: a speech wakeup mode and a non-speech wakeup mode;
Step S202, configuring an equalizer parameter of the wireless sound box according to the information of the wakeup mode, where said configuring an equalizer parameter of the wireless sound box according to the information of the wakeup mode comprises: configuring, under the speech wakeup mode, the equalizer parameter to be a first mode parameter for regulating a nonlinear distortion, and configuring, under the non-speech wakeup mode, the equalizer parameter into a second mode parameter for regulating an output sound effect.
The steps S201 and S202 in this embodiment are the same as steps S101 and S102.
Descriptions of steps S101 and S102 can be referred for details, thus would not be described herein again
