Problems solved by technology

[0004] However, the rear cavity of the speaker box in the related art can be expanded. Under different rear cavity volumes, different audio parameter settings are required. If only fixed audio parameter settings are used, then under certain expanded rear cavity volumes , the quality of the sound will deteriorate, and even the speaker box will be irreversibly damaged

Embodiment 1

[0044] see figure 1 As shown, the present invention provides an audio parameter adaptive adjustment method, which is applied to an audio system with a speaker box, and the speaker box has a variable-volume rear cavity.

[0045] The audio parameter adaptive adjustment method includes the following steps:

[0046] Step S1, acquiring volume data of the rear cavity.

[0047] The variable volume of the rear chamber can cause a volume change through a structural change of the rear chamber, thereby changing the acoustic performance of the speaker box. The rear cavity is used to improve the low-frequency acoustic performance of the speaker box. Of course, it is not limited thereto, and the audio parameter adaptive adjustment method of the present invention may also be applied to the variable-volume front cavity of the speaker box.

[0048] The speaker cabinet includes a sensor through which the audio system obtains the volume data. In this embodiment, the sensor is installed in th...

Embodiment 2

[0059] see Figure 4 as shown, Figure 4 It is a flow chart of the audio parameter adaptive adjustment method according to Embodiment 2 of the present invention. The difference between the audio parameter adaptive adjustment method in Embodiment 2 and the audio parameter adaptive adjustment method in Embodiment 1 is that the acquisition of the volume data of the rear cavity in the step S1 adopts a microphone method.

[0060] In the implementation manner of the second embodiment, the audio system further includes a microphone and a processor electrically connected to the microphone. For example, the audio system is a mobile phone, and the mobile phone is equipped with a microphone.

[0061] The audio parameter adaptive adjustment method includes the following steps:

[0062] Step S01 , before the speaker box plays the audio, play a test audio with a fixed frequency and a fixed sound amplitude.

[0063] Step S1, acquiring volume data of the rear cavity. Wherein, the step S1...

Abstract

The invention discloses an audio parameter adaptive adjustment method which is applied to an audio system with a loudspeaker box, the loudspeaker box is provided with a rear cavity with a variable volume, and the method comprises the following steps: S1, acquiring volume data of the rear cavity; S2, adjusting audio configuration parameters of the audio system according to the acquired volume data,so that the audio configuration parameters are matched with the acquired volume; and S3, processing audio data according to the adjusted audio configuration parameters, and sounding the processed audio data through the loudspeaker box. The invention further discloses an audio system applying the audio parameter adaptive adjustment method. Compared with the prior art, the audio parameter adaptiveadjustment method and the audio system are good in acoustic performance.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to an audio parameter self-adaptive adjustment method and an audio system applied to electronic sound box products. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, speaker boxes for playing sound are widely used in current smart mobile devices. [0003] The speaker box in the related art includes a variable-volume rear cavity, and the rear cavity of the speaker box can be expanded, so that the acoustic performance of the speaker box is flexible, adaptable to various application scenarios, and provides a good user experience. [0004] However, the re...
