Factors affecting the resistance value (i.e., the voice coil impedance value) of the speaker in the environment include temperature and/or humidity, so that the current environment may include the current temperature, the current humidity, the current temperature and the current humidity.
The change of the environment changes the resistance value of the loudspeaker and the response of the loudspeaker, and the corresponding relation between the environment and the resistance value of the loudspeaker and the corresponding relation between the environment and the response of the loudspeaker can be determined before the step, so that the corresponding relation between the resistance value of the loudspeaker and the response of the loudspeaker is determined. In order to facilitate sound effect adjustment, a standard response is usually required to be set as a reference for adjustment, in this embodiment, a difference between a speaker response and the standard response may be calculated to obtain a speaker response difference, and then, a corresponding relationship between a speaker resistance value and a speaker response is obtained by combining a corresponding relationship between the speaker resistance value and the speaker response difference, and a corresponding relationship between the speaker response value and the speaker response difference may be obtained.
