All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic flow chart of a parameter determination method according to an exemplary embodiment of the present application. In particular, the parameter determination method provided by the embodiment of the application is applied to the wireless headset comprising the headset local equalizer.

As shown in fig. 1, a parameter determination method provided in an embodiment of the present application includes the following steps.

And step S10, receiving the device-side equalization parameters sent by the electronic device connected with the wireless headset. The equipment end equalization parameters correspond to the audio files to be played.

In an embodiment of the application, the electronic device is a device such as a mobile phone or a tablet computer connected to the wireless headset, and the user sends the device-side equalization parameter corresponding to the audio file to be played by operating the mobile phone or the tablet computer, and the wireless headset acquires and receives the device-side equalization parameter.

In an embodiment of the present application, the device-side equalization parameters mentioned in the foregoing embodiments include default equalization parameters of the electronic device or custom equalization parameters set by a user.

Step S20, determining an equalization judgment parameter corresponding to the headphone local equalizer based on the first headphone-side equalization parameter and the device-side equalization parameter corresponding to the headphone local equalizer.

In an embodiment of the present application, the local equalizer of the headphone determines a first headphone end equalization parameter of an audio file to be played according to related information such as a genre of music, a style of music, a musician, an album, a single song, or even words and sentences in the single song of the audio file to be played, and then performs a spectrum equalization operation on the audio file to be played, so that the wireless headphone can play the equalized audio file after the spectrum equalization operation.

It should be noted that, if the frequency response of the audio file to be played does not conform to the target frequency response due to the reasons of the device-side equalization parameter, such as undertone, overshoot, mistone, and trip limit, the electronic device or the wireless headset may make a judgment on the situation, specifically, determine the equalization judgment parameter corresponding to the local equalizer of the headset based on the first headset-side equalization parameter corresponding to the local equalizer of the headset and the device-side equalization parameter, and prompt the user to perform further operations according to the equalization judgment parameter.

In an embodiment of the present application, the equalization parameter at the first earphone end is

The equalization parameter at the equipment end is EQ_a(f) The information of the loudspeaking path transfer function is G (f), and the frequency response of the audio file to be played is T (f), wherein the information of the loudspeaking path transfer function G (f) is the transfer function of the sound signal received by the wireless earphone. The product of the first headphone end equalization parameter corresponding to the headphone local equalizer and the device end equalization parameter is the equalization judgment parameter corresponding to the headphone local equalizer, that is, the following formula (1).

As shown in the above formula (1), the equalization judgment parameter is the frequency response t (f) of the audio file to be played.

In one embodiment of the present application, the frequency response is defined as the frequency response of the system through which the audio file to be played is converted by an electrical signal into an acoustic signal received by the tympanic membrane of the human ear.

In an embodiment of the present application, the first headphone-side equalization parameter is an initial value of a headphone local equalizer parameter.

And step S30, determining a second earphone end equalization parameter corresponding to the earphone local equalizer based on the equalization judgment parameter and the earphone target frequency response information corresponding to the audio file to be played.

In an embodiment of the present application, if the frequency response of the audio file to be played does not conform to the target frequency response, the user is prompted to "the wireless headset is not currently in the best tone quality" and the like, at this time, the user needs to confirm the information adjusted to the best tone quality or not adjusted to the best tone quality, and determine the second headset end equalization parameter corresponding to the local headset equalizer based on the target frequency response information of the headset corresponding to the audio file to be played.

In an embodiment of the present application, the second headphone-end equalization parameter is an equalization parameter of a headphone local equalizer corresponding to an audio file to be played after the user confirms that the audio file to be played is adjusted to the best tone quality or is not adjusted to the best tone quality. Specifically, if the wireless earphone receives the confirmation adjustment information sent by the user, the second earphone end equalization parameter is determined based on the equalization parameter and the earphone target frequency response information; and if the wireless earphone receives the confirmation non-adjustment information sent by the user, determining the first earphone end equalization parameter (namely the initial value of the earphone local equalizer) as the second earphone end equalization parameter.

That is, it can be understood that different audio files to be played have different headphone target frequency response information. For example, when the playing audio of the wireless headset is switched from the audio file a to the audio file B, the target frequency response information of the headset is also switched accordingly, and the target frequency response information of the headset corresponding to the audio file a is switched to the target frequency response information of the headset corresponding to the audio file B.

c. And the user performs switching operation of the audio file through the wireless earphone application program, the electronic equipment obtains the earphone target frequency response information corresponding to the audio file B, and determines the first earphone end equalization parameter according to the earphone target frequency response information corresponding to the audio file B, so that the first earphone end equalization parameter is sent to the wireless earphone to perform adjustment operation of the first earphone end equalization parameter locally.

In an embodiment of the present application, an audio file to be played is input to a target frequency response model (the target frequency response model is a deep learning network model) to determine target frequency response information of an earphone. The target frequency response model is obtained through model training. Specifically, an initial network model is established, an audio file sample to be played and earphone target frequency response information corresponding to the audio file sample to be played are determined to generate training data, then the initial network model is trained based on the generated training data, model parameters of the initial network model are adjusted, and finally the target frequency response model is generated.
