The device is provided with n position detecting devices in turn around the sound outlet, and the device can be an independent audio device or an audio device. The terminal device of the device. As shown in FIG. 1, the method can include:

Step 101: Acquire n detection distances.

Here, the detection distance is a distance from the obstruction detected by the n position detecting devices, and n is a positive integer. The position detecting device divides the sound emission range of the sound outlet into n sound emitting regions, and each position detecting device corresponds to one sound emitting region. The position detecting device may include a distance sensor or other device capable of detecting a distance. As an embodiment, the position detecting device is a distance sensor.

Here, the number of occluded position detecting devices indicates the number of occluded sounding regions.

Specifically, it is assumed that there are four position detecting devices in the vicinity of the sound outlet, the first position detecting device is disposed on the left side in the longitudinal direction of the sound outlet, and the fourth position detecting device is disposed on the right side in the longitudinal direction of the sound outlet. The remaining position detecting device is disposed on one side of the length of the sound outlet. If only the detection distance detected by the first position detecting device or the fourth position detecting device is less than or equal to the preset threshold, it is determined that the number of occluded position detecting devices is 1; if only the first position detecting device And the detection distance detected by the second position detecting device is less than or equal to the preset threshold, determining that the number of occluded position detecting devices is 2; if only the fourth position detecting device and the third position detecting device detect If the detected distance is less than or equal to the preset threshold, it is determined that the number of occluded position detecting devices is 2; if only the first position detecting device, the second position detecting device, and the third position detecting device detect If the detection distance is less than or equal to the preset threshold, it is determined that the number of occluded position detecting devices is 3; if only the fourth position detecting device, the third position detecting device, and the second position detecting device detect If the detection distance is less than or equal to the preset threshold, it is determined that the number of the occluded position detecting devices is 3; if the detection distance detected by the four position detecting devices is less than or equal to the preset threshold , It is determined that the position detector is blocked The number of pieces is 4. It is to be noted that the above-described position detecting device for judging the number of blocked position detecting devices is required to include a position detecting device for detecting the longitudinal direction of the sound outlet and a position detecting device for the width direction of the sound outlet.

As an implementation manner, before the determining that the number of occluded position detecting devices is i, the method further includes: calculating a first average value of the obtained n detecting distances; if the first average value is less than or equal to The preset threshold is determined by a preset threshold.

Here, since the present embodiment writes a parameter adjustment method in the current detection period, the saved maximum detection distance is the maximum detection distance saved from the first detection period to the previous detection period; n acquired The maximum detection distance in the detection distance is the maximum detection distance saved in the current detection period.

Step 103: Adjust the currently used audio parameter to an audio parameter corresponding to i according to the correspondence between the number of occluded position detecting devices and the audio parameter.

Here, the corresponding relationship between the position detecting device and the audio parameter is as shown in Table 1, and may include: when the two position detecting devices are occluded, that is, when the sound emitting regions corresponding to the two position detecting devices are blocked, the currently used The audio parameter is adjusted to the second audio parameter; when the three position detecting devices are occluded, that is, the sound regions corresponding to the three position detecting devices are occluded, the currently used audio parameters are adjusted to the third audio parameter; when 4 positions are The detecting device is occluded, that is, when the sound-emitting area corresponding to the 4-position detecting device is occluded, the currently used audio parameter is adjusted to the fourth audio parameter; and so on, the m position detecting devices are occluded, that is, the entire sound-emitting range When occluded, adjust the currently used audio parameters to the mth audio parameter. Here, if only one position measuring device is occluded, the currently used audio parameters are adjusted to the initial audio parameters.

Here, the detection distance from the obstruction detected by the ABC is less than or equal to the preset threshold. Correspondingly, the detection distances of the obstructions detected by the remaining DE are greater than a preset threshold; the detection of the obstruction detected by the CDE The distances are all less than or equal to the preset threshold. Correspondingly, the detected distances from the obstructions detected by the remaining ABs are greater than a preset threshold.

Correspondingly, the detection distance from the obstruction detected by E is greater than a preset threshold; the detection distance of the obstruction detected by the BCDE is It is less than or equal to the preset threshold, and correspondingly, the detection distances of the remaining A detected from the obstruction are greater than a preset threshold.

Step 213: If the detection distances of the obstructions detected by the five distance sensors are less than or equal to the preset threshold, the processor determines that the number of occluded sensors is 5.

Step 214: The processor adjusts the currently used audio parameter to an audio parameter corresponding to the number of occluded sensors according to the correspondence between the occluded distance sensor and the audio parameter.
