In this embodiment, the 1 st device, any one of the 2 nd devices, and the 3 rd device may be referred to as designated devices, for example, a user may determine in advance that one designated device is used to collect distance information between the 1 st device and each of the 2 nd devices, but not limited thereto, the multi-channel sound box system may automatically select the 1 st device or any one of the 2 nd devices as the designated device, and may also select the 3 rd device, for example, a cloud device, as the designated device.
In this embodiment, when the designated device is any one of the 2 nd devices, the 2 nd device may communicate with other 2 nd devices, but is not limited thereto, each of the 2 nd devices may also communicate with each other, for example, the 2 nd devices may be connected in a Wireless or wired manner, and for example, each of the 2 nd devices may communicate with other 2 nd devices in a Wireless manner such as Bluetooth (BT), Wireless Fidelity (WIFI), Microwave (Microwave), ZigBee (ZigBee), cellular mobile (cellular mobile), and the like.
In this embodiment, each 2 nd device may send the determined distance information to the designated device, and the designated device may determine the reference distance information according to all the received distance information, for example, the reference distance information may be a reference distance, for example, the designated device may select a distance between the 2 nd device closest to the 1 st device and the 1 st device as the reference distance, but is not limited thereto, for example, a distance between the 2 nd device farthest from the 1 st device and the 1 st device may also be selected as the reference distance, or a distance between any one of the 2 nd devices and the 1 st device may be selected as the reference distance, which is not limited by the present invention. The reference distance information may be other information related to the reference distance, for example, the reference distance information may be information related to the distance between each 2 nd device and the 1 st device, and for example, the difference between the distance between each 2 nd device and the 1 st device and the determined reference distance may be the reference distance information of the corresponding 2 nd device, but the present invention is not limited thereto, and for example, when the reference distance is the distance between the 1 st device and the 2 nd device which is farthest therefrom, the reference distance information corresponding to each 2 nd device may be the difference between the reference distance and the distance between the 2 nd device and the 2 nd device.

For example, the 1 st device may calculate the distance between the 1 st device and each 2 nd device in conjunction with the propagation velocity of the radio wave from the time when the 1 st device transmits the radio wave and the time when the reflected signal is received from the 2 nd device.
In this embodiment, in step 102, the 1 st device may determine the reference distance information according to the calculated distance information between the 1 st device and each 2 nd device, for example, the reference distance information may be the reference distance or the difference between the distance between each 2 nd device corresponding to each 2 nd device and the 1 st device and the reference distance, and the foregoing description may be referred to for the reference distance information. The reference distance information may include distance information and a reference distance. The invention is not so limited.

In this embodiment, when determining the delay parameter in step 103, each designated device may determine the delay parameter of each 2 nd device and send the delay parameter to each 2 nd device, but the present invention is not limited thereto, and each 2 nd device may also send the delay parameter to each 2 nd device according to the received signalThe received reference distance information determines respective delay parameters, for example, the 2 nd device and each designated device may calculate the delay parameter of each 2 nd device according to the following formula: (d)i-d)/λ, wherein di(i ═ 1, … … n) is the distance of each 2 nd device from the 1 st device, d is the reference distance, and λ is the wavelength of the reference audio signal, for example, the audio signal at 1K Hz may not be used as the reference audio signal, but the present invention is not limited to this, and other reference audio signals may be used at other frequencies, or when d is the distance between the 2 nd device farthest from the 1 st device and the 1 st device, the formula (d-d) may be followedi) The/λ calculates the delay parameter of each 2 nd device, but the invention is not limited thereto. In addition, when the reference distance information received by the 2 nd device is the difference D between the 2 nd device and the reference distancei(i-1, … … n), each 2 nd device may be according to formula DiAnd/lambda calculating the time delay parameter of each 2 nd device. After the delay parameters of each 2 nd device are calculated in the designated device, the designated device may send the delay parameters to the corresponding 2 nd devices, respectively, and the 2 nd device that receives the delay parameters adjusts the signal output according to the delay parameters.
